Abstract
This Working Paper should not be reported as representing the views of the IMF.
The views expressed in this Working Paper are those of the author(s) and do not necessarily represent
those of the IMF or IMF policy. Working Papers describe research in progress by the author(s) and are
published to elicit comments and to further debate.

In today’s financial system, complex financial institutions are connected through an opaque
network of financial exposures. These connections contribute to financial deepening andgreater savings allocation efficiency, but are also unstable channels of contagion. Basel III
and Solvency II should improve the stability of these connections, but could have unintended
consequences for cost of capital, funding patterns, interconnectedness, and risk migration.

I. INTRODUCTION
1.
Efforts to strengthen the quality of capital for banks and insurers throughBasel III and Solvency II are well advanced. On the one hand, the Basel Committee on
Banking Supervision (BCBS), the organization responsible for developing international
standards for banking supervision, adopted the Basel II framework in 20041 and, in responseto the financial crisis, has taken steps to strengthen it in an incremental fashion to form what
is now known the Basel III framework (BCBS 2009, 2011a, 2011b, and 2011c). On the other
hand, the European Commission (EC) is leading the Solvency II project, in close cooperation
with the European Insurance and Occupational Pensions Authority (EIOPA), to develop
harmonized standards for insurance supervision within the European Union. A directive wasadopted in 2009, and work—which included a series of quantitative impact studies2—hasbeen underway to develop supporting rules.3
2.
The regional scope of application of the two accords varies. Basel is an“accord”/agreement with no legal force but potentially global applicability, whereas
Solvency II is a legal instrument that will be binding in 30 European Economic Area (EEA)
countries4 (27 European Union (EU) states plus Iceland, Liechtenstein, and Norway).
However, Solvency II has also implications beyond Europe through, for example, its
influence on the international standards being developed by the International Association of
Insurance Supervisors (IAIS), and because external insurance groups will be more easily able
to operate in the EU if their home supervisory regimes are considered equivalent.
3.
Although these standards have much in common, differences do exist. Both take arisk-based approach to minimum capital requirements and supervision and promote theintegrated use of models by institutions in managing risks and assessing solvency. However,their objectives overlap only partially. In particular, Basel III attempts to increase the overall
quantum of capital and its quality as a means of protecting against bank failures, including
improved quantification of risks that were poorly catered for under Basel II. However,
Solvency II attempts to strengthen the quality of capital and tailor the quantity of capitalrequired more closely to the risks of each insurer, without necessarily increasing the quantity

The latest version of the Basel II framework is given by BCBS (2006) which includes the updates andrevisions.

Commonly referred to as Level 2 and Level 3 rules in the EU implementation process.

For this reason, the introduced would differentiate between “accord” for Basel and “Directive” for Solvency
II. Taxonomy becomes complicated also because the “Basel Accord” is often referred to as the “Solvency
Accord.” At the risk of sacrificing formal precision in favor of simplicity, we will call them either “accords,” or“standards” or “frameworks” interchangeably.

within the sector as a whole. Finally, the two accords have been tailored to the businesscharacteristics of the respective sectors, often as a result of bilateral negotiations, and shapedby the views of those involved in their development in a piecemeal manner. Accordingly,
they have generated long and complex documents which define the same concepts indifferent ways and often deal differently with the same or similar issues.
4.
This paper has two key objectives: (i) to present similarities and differences among
Pillar 1 requirements of the two accords; and (ii) to discuss possible unintended
consequences of their implementation. In order to ensure focus in the analysis, this paper isintentionally limited to aspects related to Pillar 1 (minimum capital requirement) in the twocapital accords. The paper acknowledges that there can be significant overlap in the businessactivities of banks and insurers. For example, consumers save with banks through deposits
and with life insurers through annuity with savings products. In addition, banks and insurers
invest in many of the same types of assets and they compete with one another in raising
capital, both in the capital markets and within the financial conglomerates of which many are
members. Due to this overlap, differences in the two accords can generate unintended
consequences in the area of cost of capital, funding patterns, and interconnectedness, andpromote risk/product migration across or away from the two sectors. These unintended
consequences are summarized in the conclusions together with policy considerations. Finally,
the paper acknowledges that other sources of arbitrage not analyzed in this paper, likedifferences in Pillar 2 (supervisory approach) and Pillar 3 (market discipline), as well as
differences in accounting (partially discussed here) and tax treatments, could reinforce oroffset the impact of differences in the capital regulatory frameworks.
5.
The remainder of the paper is structured as follows: Section II discusses
differences and similarities between the insurance and banking business models, thevaluation and accounting of assets and liabilities, as well as the ability of the two types offinancial intermediaries to change the risk profiles of their balance sheets. Section III
provides a succinct overview of the two accords. Section IV discusses differences andsimilarities in the capital components provided for under the two accords. Section V
discusses differences and similarities in the required capital under the two accords. The
possible implications of these differences are discussed within each section, while Section VI
reflects on the overall picture. Finally, Section VII concludes and draws policy
considerations.
II. BANKS AND INSURERS ASSETS AND LIABILITIES
6.
While different, business activities of banks and insurers often overlap. The
business differences affect the nature of their assets and liabilities, the manner in which these
entities are funded, and the overall structure of their balance sheets. Accounting rules, which
affect the valuation of assets and liabilities—and the resulting level of capital—also differ insome respects by sector. At the same time, banks and insurers compete on both investment
and protection products. In summary, while the banking and insurance businesses are7fundamentally different, substantial overlap exists in key areas. This section discusses
similarities and differences in business models, accounting standards, ability to modify therisk profile of assets and liabilities, and product competition between the two sectors.
A. Differences in Business Model
7.
Banks’ business is asset-driven and often supported by leveraged balance sheets.
Banks provide a large set of fee-based services, such as payment and settlement processing,and financial services. Commercial/retail banks provide mainly loans to borrowers, typicallyfunded by pooling the savings of depositors; i.e., the business is based on maturity
transformation and the loan books represent the largest component of their assets while
deposits represent the largest components of their liabilities. However, if deposits are
insufficient to support the growth of the loan book, banks leverage their balance sheet byseeking additional funding by issuing commercial paper or bonds, borrowing from otherbanks or the central bank, or engaging in securities repurchase transactions (repos).
Investment banks provide a large set of financial services to clients and engage in securities
trading activity for both their customers’ accounts and their own account. The funding
needed to support trading activities and their associated risks typically comes fromshareholders or wholesale sources. Finally, universal banks combine both commercial andinvestment banking activities. Accordingly, their assets, liabilities, and funding sources sharecharacteristics with both commercial and investment banks.
8.
Different activities subject banks to different risks. The loan book subjects a bankto credit risk, should borrowers default on the obligation to repay their loans, but such credit
risk is capped by the value of the loans. The loan book (in combination with short term
funding) also subjects a bank to liquidity risk. Indeed, the duration of deposit liabilities istypically shorter than the duration of loan assets. This maturity transformation usually serves
to enhance the spread, but it can subject a bank to significant liquidity risk which, in turn,contributes to the need to protect depositors with safety nets. In addition, since there is no
direct link between the liabilities and the assets,5 if there is a run on the bank, where
customers withdraw their deposits and other banks refuse to provide interbank loans, the loan
assets might not be readily realizable. Investment, and universal and commercial banks arealso exposed to market, counterparty, and operational risk through their trading books.
Finally, fee-based services subject banks to operational risk and, in some cases, tocounterparty credit risk.
9.
Banks’ profits arise from the spread between the income earned on assets andthe cost of liabilities. Fee-based services generate fee income. The loan book produces
interest income and the trading book produces investment income. On the liability side, costs
5This stems from the “asset” driven business model of banks as opposed to the “liability” driven model of
insurers as will become clearer later.

8of funding are represented by the interest paid on deposits and/or the costs of alternative
sources of funding.
10.
Insurers typically provide a narrower range of services that are mainly liability
driven (Geneva Association, 2010). The core activity of nonlife insurers is limited to riskpooling arrangements to protect policyholders from adverse future events. The life businessincludes products that can serve as investment vehicles for policyholders. Such products
often combine the investment aspect with insurance protection—against mortality or
longevity risk—and can be very long in duration.
11.
Insurance activities generate mainly underwriting, credit, and market risk. The
policyholder protection activity exposes both life and nonlife companies to underwriting risk,
market risk, and perhaps (depending on the guarantees provided by the policy) credit risk.
Life products (especially when combined with savings components) can also create liquidity
risk, although many include restrictions or penalties intended to mitigate this risk. For someclasses of nonlife insurance business, such as credit insurance and financial surety, theunderwriting risk is similar to the credit risk borne by a bank. Finally, insurers typically seek
to invest the premiums in assets that are suitable to the nature of the corresponding insurance
liabilities. Mostly, there is a close and direct link between the value of the insurance liability
and the value of the related assets. However, when adequate assets are not available, theduration of an insurer’s liabilities is often longer than the duration of its assets. Any interest
rate duration mismatch creates market risk for the insurer in the form of interest rate risk, butsome investment types (i.e., asset-backed securities) can also create credit spread duration
risk.
12.
Insurers are less leveraged and therefore, less exposed to liquidity risk thanbanks. Insurers are largely funded by policyholders with technical provisions6 representing
the largest component of insurers’ balance sheets and they are less reliant on debt and otherexternal funding than are banks (Figure 1).7 However, some life insurance products generate
losses (under current methods of calculating liability values) during the first years of thepolicy8 and insurers sometimes purchase reinsurance or use own capital to help meet this new
6

Technical provisions represent the amount set aside on the balance sheet to meet liabilities arising out of
insurance contracts, including claims provision (whether reported or not), provision for unearned premiums,
provision for unexpired risks, life assurance provision and other liabilities related to life insurance contracts(i.e., premium deposits, savings accumulated over the term of with-profit policies). Other commonly used terms
are “technical liabilities” and “reserves.”

7

For example, the aggregate balance sheet of a group of European banks consists on average of a significant
portion of instantaneous callable or short-term funding, which is much shorter than the average duration offunding of a sample of European insurance companies ranging between 8 to 10 years.

For instance, competitive pricing implies that the individual life business is capital-intensive in the first yearsof development with capital being recuperated though profits only over time.

9business strain. Insurers are less exposed to the risk of mass lapses of policies than are banks
to runs on deposits because of the locked-in nature of much of their funding. The ability of
insurers to anticipate future profits under Solvency II could increase the exposure to mass
lapses, because it means that some might not have sufficient readily-available capital to repay
all policyholders in the event of a run. However, the mass lapse stress component in thesolvency capital requirement (SCR) helps to mitigate this risk.9

13.
Insurance profits arise from the difference between income earned and the costsof providing insurance benefits. The relative importance of the different income andexpense items varies by business line, but, in general, the largest source of income istypically represented by policyholders’ premiums followed by the investment income that
accumulated premiums generate prior to the payment of insurance benefits. The largest
component of expenses is typically constituted by claims payments to which underwriting,reinsurance, investment, and administrative expenses need to be added.
14.
Insurance liabilities have more loss-absorption capacity than bank liabilities.
Insurance liabilities, particularly those in respect of life insurance policies with profit
participation, provide some risk-absorption capacity. If experience is adverse and there is
profit participation in place, some of the adverse impact would reduce policyholder
liabilities, thereby mitigating the impact on capital. Although the same partial pass-through9

There is a limit to the extent with which insurers can take credit for future profits as this depends on uncertain
policyholder behavior. The scope for this may reduce with Solvency II if the ‘best estimate’ computation of theliability fully takes into account expected policyholder behavior in such circumstances

can also arise in banking (for example, with a derivative contract, if defined in an appropriatemanner), such contract terms are much less common than in insurance.

15.
These differences in business models translate into differences in both levels andquality of capital (Figure 2). The largest 50 European banks have on average 6 percent total
capital over total assets, of which only 67 percent is represented by high-quality Core Tier 1
capital. Large insurers world-wide have on average 8 percent of total capital over total assets,of which 84 percent is represented by high-quality equity capital. Finally, large global
reinsurers10 have on average more capital (with total capital amounting to 15 percent of total

assets) but are also more leveraged (with high quality equity capital amounting to 73 percent
of total capital).11
B. Key Differences in Accounting Standards
16.
Banks and insurers use different accounting standards.12 In many jurisdictions,the financial statements of banks are prepared in accordance with International Financial
Reporting Standards (IFRS) or similar accounting rules. The rules are a mixture of fair-value
accounting (for trading activities and available-for-sale banking assets) and historical costaccounting (for other banking assets). The accounting standard was not designed specificallyfor banking regulatory purposes, so various adjustments and deductions are made in movingfrom the financial statements to the determination of capital adequacy. Solvency II uses
instead a “total-balance-sheet approach” based on the fair values of both assets and liabilities.
The Solvency II balance sheet must be prepared independently of any general-purpose
financial reporting requirements. Although some assets and liabilities will be valued in thesame manner as under IFRS, others will be valued differently.13 Given the different
underlying accounting bases, it is unsurprising that the prudential adjustments under
Solvency II differ from those under Basel III (as we will see in Section IV.B).
17.
Bank assets are typically valued at amortized book value or fair value. Bankloans, under IFRS, fall under financial instruments and are accounted for by using IAS 39.
Under IAS 39, financial assets are categorized as either (i) loans and receivables;(ii) financial assets at fair value through profit or loss; (iii) available for sale; or (iv) held tomaturity. Other financial assets are initially measured at fair value plus, if not valued at fairvalue through profit or loss, transaction costs that are directly attributable to the acquisition.
Financial assets at fair value and assets available for sale are subsequently carried at fairvalue, while loans and receivables and held-to-maturity assets are carried at amortized cost.
All derivatives, whether held for trading or for hedging, are carried at fair value. IFRS 9,which will apply from January 2013, proposes that all financial assets will either bemeasured at amortized cost or fair value.

11

The information reported is (strictly speaking) not comparable as capital levels and quality should be risk
adjusted. Ideally, comparison should be made in terms of VaR at the same confidence level and time horizon.
12

Both banks and insurers use a variety of accounting approaches, the description of which is beyond the scopeof this paper. Here we limit the analysis to key differences related to the stability of valuations and therefore,
capital.
13

It is important to highlight that all assets and liabilities will be valued according to the same framework
irrespective of whether this is in the same manner as IFRS or not.

12
18.
In addition, loan provisions are only “retrospective.” Banks are not permitted tomake provisions for expected future loan losses, no matter how likely they are to arise.14
IAS 36 “Impairment of Assets” requires a case-by-case assessment of the facts andcircumstances surrounding the recoverability and timing of future cash flows relating to acredit exposure. Should there be an expectation that all contractual cash flows would not berecovered (or recovered without full future interest payments), an exposure would beclassified as impaired. The extent of impairment would be measured on a present-value basis
using the effective interest rate of the exposure as the discount rate. For groups of loans thatshare homogenous characteristics (such as mortgage and credit card receivables), impairment
can be assessed on a collective basis. The aim of an individual or collective assessment is tocapture the incurred loss for a specified portfolio. General provisions are permissible only tothe extent that they relate to a specified risk that can be measured reliably and for incurred
losses. For investments, a similar analysis is conducted, the key difference being that the fairvalue of the investment is also considered as an input.
19.
However, the assets of insurers are valued at fair value under Solvency II andprovisions are prospective. IFRS is used as a proxy for fair value, except for some specificinstances when IFRS is not equivalent to fair value. Provisions for expected losses on theassets of insurers would thus be inherently reflected in the valuation.
20.
Bank liabilities are also valued at amortized book value or fair value. Bank
deposits are typically valued at book value or amortized book value. A retrospective
methodology is used, reflecting the amount that would be paid upon exit. Other financial
liabilities of banks are initially measured at fair value plus, if not valued at fair value throughprofit or loss, transaction costs that are directly attributable to the acquisition. After initialrecognition, financial liabilities can be carried either at amortized cost using the effective
interest method or at fair value through profit or loss. A new accounting standard, IFRS 9,
will apply from January 2013 and will require companies choosing to measure a liability atfair value to present the portion of the change in its fair value due to changes in the entity’s
own credit risk in the other comprehensive income section of the income statement, rather
than within the profit and loss.
21.
However, insurance liabilities under Solvency II are valued at the amount for
which they could be transferred or settled between knowledgeable willing parties in anarm’s-length transaction. The values can be calculated using one of two methods: best
14

Provisions are created following an “incurred loss” approach. The push towards the “incurred loss” approach
was built on the fact that in the past there had been abuses of provisioning for “expected losses” which had
become “cookie jars” so that banks could “smooth” profits over time. Related to this is the limited recognitionof banks provisions within the capital base (while insurers can fully recognize excess provisions in the capitalbase. In other words, the Basel accord discourages banks (relative to insurers) to be overly cautious inprovisioning.

13
estimate plus risk margin; or as a whole. The first methodology involves projecting theprobability-weighted future cash flows and required capital associated with the insurer’s
obligations and discounting the results back to the valuation date. The risk margin is included
to ensure that the value is equivalent to the amount that another insurer would likely requirein order to take over the insurance obligations. The cost-of-capital rate most recently tested
was 6 percent. The best estimate liability may be negative. The second methodology uses themarket value of a portfolio of replicating assets, which implicitly results in a prospective
valuation. This method is appropriate if the future cash flows associated with the insurance
obligations can be replicated reliably, using financial instruments for which a reliable market
value is observable, such as the obligations in respect of unit-linked products.
22.
Another difference relates to the effect of an entity’s own credit standing in thevaluation of its liabilities. Under IAS 39, a bank’s financial liabilities can be adjusted forchanges in its own credit standing. This allows a bank, the position of which is weakening, tobook profits based on its theoretical ability to buy back debt at a reduced cost. Insurers will
not have this option under Solvency II, which does not permit any adjustment to take accountof the own credit standing of the insurer. However, this accounting difference does notprovide an advantage to banks in the calculation of regulatory capital, because Basel III
requires that common equity Tier 1 capital (CET) be adjusted by cumulative gains and losses
due to changes in own credit risk on fair-valued financial liabilities.
23.
These differences in accounting standards for banks and insurers suggest thefollowing:Banks have greater flexibility than insurers regarding the valuation of financial
liabilities. Banks can value liabilities using either amortized cost or at fair value
through the profit and loss—although a bank cannot freely switch valuation bases,
while insurers will be required to value them at fair value under Solvency II. The
reported values of financial liabilities that are valued at amortized cost are morestable than those valued at fair value, which will move in response to changes ininterest rates.



The retrospective valuation of bank balance sheet items generates greater stability inthe reported values. Banks have the ability to classify financial assets as loans or held
to maturity, which enables them to value the assets using amortized cost. The assets
of insurers change in value as interest rates move or credit spreads change, whereasbank assets that are valued using amortized cost will not. Even the new approach
proposed by the International Accounting Standards Board (IASB) would still differ
from a fair-value approach because, for example, movements in credit spreads will
not automatically result in any change to the valuation of the asset. It is not until aloss event occurs that the bank would move the asset from the good book to the badbook and recognize the likely cost of default.

14

The relative prudence of the different valuation methods in provisioning of banks andinsurers depends upon the profitability of the business written. If a contract is
expected to have positive future profitability, then the retrospective approach is more
prudent, because the liability will be valued at book value and will not recognize thefuture profit that the company expects to earn on the contract. Under Solvency II, theinsurer will be able to recognize this expected future profit upon writing the contract.
However, if a contract is expected to produce future losses, then the prospective
approach is more prudent, because those losses would be recognized upfront rather
than spread over the remaining life of the contract as with the retrospective
approach.15 Another factor that affects the level of prudence is that insurers are
required to include a margin in the liabilities in respect of the cost of capital, whereasbanks do not include such a margin in their retrospective valuation of liabilities or inits loan provisioning.

24.
Finally, important changes are underway at the IASB, which will affect theaccounting of banks and insurers. In addition to the aforementioned IFRS 9, they include
changes regarding the definition (IAS 32) and classification of financial instruments(IAS 39), and the recently-issued Exposure Draft on Insurance Contracts (IFRS 4). In
addition, the IASB is currently consulting on a requirement for balance sheet loans to bear an
expected loss provision throughout their life. In November 2009, the Board issued an
exposure draft proposing the adoption of an expected loss model for recognizing credit
losses. The IASB has also agreed to incorporate an incurred loss model on top of the
expected loss model, often referred to as a good book (expected loss model)/bad book(incurred loss model) approach. The BCBS supports the use of more forward-looking
provisions. The effects of these changes are unclear.
C. Differences in the Ability to Change Assets and Liabilities
25.
Banks and insurers manage differently the risk profile of their assets andliabilities. They typically do so to reduce overexposure to particular risks or to free up
capacity to take on more business. The ways in which this is accomplished can differ
significantly by sector.
26.
Banks commonly securitize loan assets and sell them into the capital markets.
Securitization can reduce exposure to a particular type of loan, type of borrower, or
geographic area. By removing assets from the balance sheet, it may also release regulatory
capital, which can then be used to support additional loans. However, a securitization must
be of sufficient size to make the transaction economically viable. Sometimes, as in

15

Notice that there is still a significant debate ongoing regarding the classification of Expected Profits in Future
Premiums, which could substantially affect the significance of the ability to recognize profits upfront.

collateralized debt obligations (CDOs), securitizations are repackaged into anothersecuritization.16
27.
Insurers commonly use reinsurance and, less frequently, capital market
instruments to transfer risk. Reinsurance can be used to cover individual risks (i) to sharethe underwriting risk on a particular portfolio; (ii) to prevent the absolute scale of any loss
exceeding a particular amount; (iii) to stabilize experience; (iv) to provide capital support;(v) to release future profits; and (vi) to protect against catastrophes. It offers significant
flexibility to insurers to alter the nature of the risk that they hold on their balance sheet andallows them to tailor the exact form of underwriting risk that they wish to take, and it canalso be structured to transfer credit risk or market risk. Many types of reinsurance enable aninsurer to reduce the insurance liabilities held on its balance sheet. However, because an
insurer remains liable to its policyholders in respect of the benefits that have been reinsured,
reinsurance essentially transforms underwriting risk into counterparty credit risk. Thiscounterparty risk can be protected against using methods such as depositing assets back with
the insurer or providing collateral. Much less frequently, insurers limit their exposure to
extreme nonfinancial underwriting risks to others through the capital markets, using
insurance-linked securities (ILSs). Similarly to reinsurance, ILSs limit the risk exposure, butthey do not take the liability off an insurer’s balance sheet. For many insurance liabilities
there is simply no secondary market, which impacts on an insurer’s ability to offload risk andalso on the ability to value insurance liabilities.
28.
Finally, both banks and insurers use derivatives to manage risks, but generallywith different purposes. Banks use derivatives mainly to hedge exposures arising from theirtrading activities, as well as credit default swaps (CDSs) to limit risks associated with theirlending activities.17 Life insurers use derivatives to hedge exposures to market risk as part oftheir asset-liability management (ALM) programs.18
D. Different Treatment of Similar Products
29.
Banks and insurers compete both on products that are predominantly
investments in nature and those that predominantly provide protection. Examples ofinvestment products that are written by both banks and insurers include investment bonds,
term deposits offered by banks, and term-certain annuities offered by insurers. Examples ofprotection products include: (i) investment guarantees and options written by investment
16

The use of securitization and especially CDOs has drastically diminished after the 2008 crisis.

17

Later in the paper we also discuss guarantees, collateral and netting as credit risk mitigation techniques
commonly used by banks.

18

Banks use ALM programs too but less extensively than insurers as reflected by their maturity transformation
exposures.

16banks and variable annuities with investment guarantees written by insurers; (ii) CDSs
written by both banks and insurers; and (iii) trade finance offered by banks and surety bonds
offered by nonlife insurers.19
30.
Different tax and capital treatments of such products can generate opportunities
for product and capital arbitrages. Although these products offer similar economic
benefits to customers and expose financial institutions to similar economic risks, differencesin the manner in which they are taxed—with respect to either the financial institution or the
consumer—can affect the related assets or liabilities. For example, in some jurisdictions
savings products offered by life insurers provide for the deferral of tax on related investment
income until the policy benefits are paid, while the income on bank deposits is taxedannually. This may discourage withdrawals from the insurance policies, subjecting an insurer
to less liquidity risk than a bank that offers a similar savings product (unless the tax regimechanges in a way that creates an incentive for the insurance policyholder to withdraw). In
addition, differences in their capital treatment under the two accords can generate
opportunity for arbitrage across sectors as discussed in Section VI.
E. Implications
31.
The aforementioned differences between banks and insurers reflect thefundamentally different roles played by these intermediaries in the financial system.
Banks are a reflection of money serving as a means of payment in exchange. Their
comparative advantage is to screen projects and finance them over the short term. This shortterm maturity transformation calls for the existence of safety nets to protect depositors
against liquidity shocks. Insurers, instead, (especially life insurers), are a reflection of money
serving as a store of value, permitting deferred consumption and smoothing. Their
comparative advantage (strictly as investors) is to invest in long-term securities and benefit
from their illiquidity premium. The different types of intermediation of banks and insurers
already suggests capital needs to protect entities against unexpected shocks should be
different across sectors.
32.
The aforementioned differences can have a range of implications. For instance,
the assets and liabilities of insurers are more often linked to one another (due to the liabilitydriven business model of insurers and strict matching requirements of ALM programs) thanare those of banks (where links exist mainly through a network of financial exposures). This
reduces their liquidity risk and need for external funding. Also, due to liquidity risk, the needfor funding, and the effects on loan defaults, banks have more short-term exposure tochanging economic conditions than insurers. For banks, the credit risk can be transferredthrough securitization, but the liquidity and funding risks are more difficult to deal with. 20
19Naturally, the extent to which this competition is distorted by regulation is a matter of empirical investigation.

20

The recent crisis showed how banks could not escape the liquidity risk associated with many structures.

17
For insurers, reinsurance represents an additional tool—unavailable to banks—that can alter
the nature of their balance sheet. This, as discussed in Section VI, could provide insurers withadditional degrees of freedom to reduce their cost of capital. Furthermore, there is a muchgreater degree of interconnectivity among banks, especially through the interbank market,
than there is among insurers. Therefore, there is generally a much greater risk that the failureof a single bank could have systemic implications (Geneva Association, 2010). However, if
an insurer is significantly involved in activities—such as providing protection against credit
exposures—which are closely linked to the broader financial sector—then its failure could
likewise have systemic implications. Finally, insurers—especially life insurers—have more
long-term exposure to changing economic and other conditions than banks because of thenature of their liabilities. ALM can be used to help deal with the economic risks. However,
without effective ALM, the prospective nature of liability valuation can accentuate theeffects of economic changes on the balance sheet.
33.
More importantly, the aforementioned differences justify many but not all thedifferences in the respective capital accords. In particular, Basel III reflects the general
realization that capital has failed (because deemed ex post insufficient and of poor quality)
during the recent crisis to protect banks and tax payers from unexpected losses. This issue
does not primarily guide Solvency II, as insurers have proved to be more resilient to the same
shocks. Notwithstanding this observation, several differences in the two accords (as we will
see in the next sections) are not supported by differences in the nature of capital needed in
the two sectors, potentially generating unintended consequences.
III. OVERVIEW OF THE TWO ACCORDS
34.
Basel III and Solvency II aim to ensure sufficient regulatory capital is held bybanks and insurers. Basel III aims to increase the quality and level of capital (and to
reinforce banks’ liquidity risk management) in an incremental fashion to the existing regime.
Solvency II does not have the same objective: it aims to increase the protection ofpolicyholders by creating incentives for good risk management and ensuring that thequantity/quality of capital required is calibrated to risks that insurers’ are exposed to.
35.
Basel III and Solvency II have had completely different and independent
development processes. These two international accords have different histories: Basel III
has been developed over the last two years in reaction to the recent financial crisis, while
Solvency II is the first attempt to develop a fully risk-based solvency standard for theEuropean insurance industry, and has had a much longer gestation. The differences in thenature of the respective standard setters, their objectives, and their largely independent
development processes have affected the accords and their scope of application. Finally, atthe time of writing, the two accords are yet to be finalized.

18
A. Key Elements of Basel III
36.
Basel III has been developed by the BCBS in reaction to the recent financial
crisis. The BCBS consists of senior representatives of bank supervisory authorities andcentral banks from and central banks from the major financial centers, including all G20
jurisdictions.21 It is intended to apply to internationally-active banks, on a fully-consolidated
basis. Basel III evolved from the Basel II framework, and now includes liquidity
requirements and gives increased attention to dealing with system-wide issues, such as theinteraction of prudential requirements and economic conditions.
37.
In order to implement Basel III in a particular jurisdiction, its requirements
generally must be transposed into local legislation. For example, in the EU this requires a
directive as well as, possibly, regulations, which need in turn to be transposed into legislationin the member countries. Many jurisdictions that are not members of the BCBS also seek toimplement the Basel accords because of the international character of the banking business.
Furthermore, some jurisdictions apply the Basel accord, although sometimes withsimplifications, even to banks that are not internationally active.
38.
Although the basic framework of Basel II has been retained in Basel III, many of
its elements have been strengthened, including the following:22


Early reforms to Basel II were agreed in July 2009, which will raise capitalrequirements for the trading book, complex securitization exposures, andsecuritizations in both the banking and the trading books. The reforms immediately
raised the standards of the Pillar 2 supervisory review process, and the capitalrequirements and related disclosures are to be implemented by the end of 2011.

Basel III requires that Tier 1 capital must be of higher quality—focusing on common
equity; harmonizes Tier 2 capital instruments; and eliminates Tier 3 capital
instruments, which had been available to cover market risks. All elements of capitalwill be required to be disclosed, along with a detailed reconciliation to the reported
accounts. A leverage ratio will also be applied to provide an extra layer of protection
against model risk and measurement error.



It includes measures to strengthen the capital requirements for counterparty credit
exposures arising from derivatives, repo, and securities financing activities. The

Russia, Saudi Arabia, Singapore, South Africa, Spain, Sweden, Switzerland, Turkey, the United Kingdom andthe United States.
22

See BCBS (2011b) for details.

19changes were designed not only to increase capital requirements, but also to reduceprocyclicality and to provide incentives to move derivative contracts to central
counterparties.


It introduces a framework designed to promote the conservation of capital and thebuild-up of buffers that can be drawn down in periods of stress. The capital buffer
range can be adjusted in response to signs that credit has grown to an excessive level.

39.
Basel III also introduces internationally-harmonized liquidity standards.23 The
Liquidity Coverage Ratio (LCR) is designed to measure whether a bank has sufficient highquality liquid resources to survive an acute stress scenario lasting for one month, while the
Net Stable Funding Ratio (NSFR) has a time horizon of one year and helps to determine
whether there is a sustainable maturity structure of assets and liabilities.
40.
A long transition period is foreseen for the implementation of Basel III. Although
Basel III is effective from January 1, 2013, some items are subject to phase-in arrangements;for example:

The Leverage Ratio must be disclosed beginning in 2015 and becomes a Pillar 1
requirement in 2018;

The Minimum Common Equity Capital Ratio reaches its ultimate level in 2015;



Various deductions from common equity are phased in between 2014 and 2018;

The Minimum Tier 1 Capital requirement reaches its maximum in 2015;

The Capital Conservation Buffer is introduced in 2016 and reaches its ultimate levelin 2019;

Capital instruments that no longer qualify as noncore Tier 1 or Tier 2 capital arephased out over a 10-year horizon beginning in 2013; andMinimum standards will be introduced for the LCR in 2015 and the NSFR in 2018.

41.
Finally, additional reforms are also being considered. Looking to the future, theBCBS is promoting stronger provisioning practices by advocating a change in the accounting
standards toward an expected loss approach, updating supervisory guidance, and providing

23

See BCBS (2011b) for details.

20
incentives in the regulatory capital framework. It is also conducting fundamental reviews of
the trading book and the securitization framework.24
B. Key Elements of Solvency II
42.
By contrast, Solvency II originated from the European Commission and notfrom the IAIS, the insurance equivalent of the BCBS. Solvency II applies to almost all
insurers operating in the European Community. This includes small, local insurers, except for
those with gross premium income below EUR 5 million. Its requirements are also relevant toreinsurers or groups based outside the European Community but operating therein, which canbe treated more like local insurers with respect to reinsurance, group solvency, and groupsupervision if their home supervisory regimes are assessed as equivalent by EIOPA.
43.
Solvency II is broader in scope than Basel III. It attempts to create acomprehensive, principles-based system of regulation and supervision. In addition toestablishing risk-based capital adequacy requirements, it consolidates 14 existing insurance
directives and deals with such topics as the valuation of assets and liabilities, groupsupervision, and the winding up of insurers.25
44.
Several levels of legislation must be in place for Solvency II before it takes effecton January 1, 2013. The Level 1 directive was approved by the Council of Ministers and theEuropean Parliament in 2009. Various consultations and quantitative impact studies havesince taken place, including the recent QIS5. A proposed revision to the Level 1 directive
was published by the Council of the European Union on June 7, 2011 and is not expected tobe finalized until early 2012. Level 2 implementing measures are currently expected to be
published in Quarter 1 2012. EIOPA is expected to submit draft binding technical standards
to the European Commission in Quarter 2 of 2012 and to publish Level 3 guidelines in
Quarter 3 of 2012.
45.
Finally, there is a wide range of issues on which decisions remain to be taken inarriving at the final requirements and guidelines, including the following:Assessment of the adequacy of the calibration of quantitative requirements;

Determination of the risk-free interest rate curve used for discounting technicalprovisions and the use of transitional measures;24
25

See Appendix I for additional details on Basel III proposals and BCBS (2011b).

This also stems from what discussed in footnote 4. Solvency II is a directive while Basel III is a risk/capitalframework also part of directive (the Capital Requirement Directive (CRD)) which, in turn, covers a range ofother issues including some (but not all) those covered by the Solvency II directive.

Development of guidelines to allow insurers to apply for the use of an internal model;Transitional periods for a number of items;

Development of guidelines on own-risk and solvency assessment (ORSA); andDevelopment of guidelines on the supervisory review process.
C. Implications

46.
The implications of the different situations described above are somewhat
uncertain. In general, since Solvency II does not have the same explicit objective to increase
capital as Basel III, capital costs for the two sectors could rise asymmetrically, possibly
promoting inappropriate risk migration from banks to insurers. However, under both accords,
there are still aspects of the requirements that are yet to be finalized and which could result in
additional unintended consequences. Some of these, such as the calibration of quantitativerequirements, could affect the opportunities for cross-sectoral arbitrage. Within the European
Community, the overall legal and regulatory framework should produce relatively consistent
implementation of both Basel III and Solvency II from one jurisdiction to another. However,among other jurisdictions, only peer pressure will limit the variations in Basel III
implementation. The influence of Solvency II outside the European Community will be evenless certain, depending on such factors as the results of the equivalence assessments, IAIS
deliberations, and the outcome of its implementation within the European Community. In
particular, the confined geographical application of the Solvency II framework could
generate opportunities for insurers to reduce the cost of capital through the use of reinsurance
in non-equivalent jurisdictions with weaker solvency and supervisory standards, if the capitalcharges required against the credit risks introduced by such reinsurance contracts are not set
appropriately.

22
IV. PILLAR 1: COMPONENTS OF CAPITAL
47.
Pillar 1 requirements of both Basel III and Solvency II deal with two
fundamental issues: the amount of capital that is needed to support an entity’s business andits components (or types of resources) that are considered to be capital available to meetthose needs. The former is discussed in Section V of this paper, while this section deals withthe components of capital.
48.
In both accords, the primary role of capital is to absorb unexpected losses andthus enable an entity to meet its obligations. Under both accords, an entity should haveenough capital to absorb losses and support its continuation as a going concern. But at thevery least, an entity should have sufficient capital to meet its existing obligations if it were tocease carrying on business. Consequently, there are two general types of capital on thebalance sheet: (i) capital that absorbs losses on a going-concern basis; and (ii) subordinatedliabilities that absorb losses on a gone-concern basis. Subordinated liabilities help to ensurethat depositors, policyholders, and senior creditors can be repaid in the event an entity iswound up. Solvency II also recognizes certain off-balance sheet instruments as Ancillary
Own Funds (AOF): capital that can be used to meet the going-concern Solvency Capital
Requirement (SCR), but not the gone-concern Minimum Capital Requirement (MCR). In
both sectors, supervisors seek to ensure that capital will be sufficient, even under stressful
conditions, on both going-concern and gone-concern bases.
49.
Both accords follow a similar process to determine capital. General-purpose
financial statements report the assets and liabilities of an entity on a going-concern basis,
with capital being simply the excess of assets over liabilities. However, some assets might besubject to restrictions that would limit their ability to absorb losses or might lose considerable
value under stressful conditions. Accordingly, not all capital is of equal quality. In both
sectors, the determination of required capital is based on a three-step process: calculating theamount of required capital; classifying the capital into various categories; and assessing theeligibility of instruments for each category.

23
50.
Also, both accords provide for a system of capital tiers that, however, are quite
different from one another. The use of explicit capital-tiering rules has not been as
prevalent or long-standing in the insurance sector as in banking. Insurers have traditionally
had simpler, equity-focused capital structures. They have also been able to use reinsurance tostrengthen their capital positions rather than having to issue lower-quality capital
instruments. Nonetheless, although both accords define various categories of capital, they are
not consistent with one another in terms of the categories, the terminology used to describe
the categories, or the criteria applied to determine what goes into a similar category. The
categories are shown in Table 1.
51.
Some of the inconsistencies in the tiers can be explained by differences in thebusiness models. All capital recognized under Basel III is on the balance sheet, while the
AOF under Solvency II are not. The inclusion of such instruments, which can be called upon
to absorb losses in the capital available to meet the Solvency Capital Requirement (SCR)—
but not the Minimum Capital Requirement (MCR)—may be economically justified because
the insurance business is less subject to the risk of runs.
52.
However, some of the inconsistencies have no basis in business or valuationdifferences. Examples include differences related to regulatory adjustments to capital, suchas intangibles other than goodwill, deferred tax assets, and excess assets related to employee
pension benefits. For instance, the tightened requirements under Basel III to avoid doublegearing stemming from equity participation in subsidiaries still allow for exceptions thatprovide some scope for double-gearing, even if more stringent risk weighting is used tocompensate in such situations.26
53.
Basel III has reformed the treatment of market risk and eliminated Tier 3
capital. Although Basel II provided for three tiers of capital, the classification structure
under Basel III has been simplified into two tiers: Tier 1 is going-concern capital; and Tier 2
is gone-concern capital. Basel III includes a series of classification criteria, which relate topermanence, loss absorbency, and flexibility of payments. Within Tier 1, the common equity
component (CET) has been specifically identified because a minimum portion of the required
capital must be met using common equity. Tier 3 instruments, which can be used under
Basel II to cover market risk, large exposures in the trading book, and fixed overhead
requirements, are not eligible capital under Basel III.

26

Regulatory adjustments to capital are discussed in detail later in this section.

24
Box 1. Basel III Bail-in Capital Proposals
Bail-in refers to a scenario where non-equity claims are converted into equity to facilitate resolution of
institutions. Upon a trigger event (which need not be the point of non-viability), senior creditors’ and regulatory
capital providers’ claims are reduced to create equity and allow a bank to continue as a going concern. Bail-in
instruments can be contractual when the trigger is pre-determined in the contractual provisions between theissuer and the investor (as in the case of convertible bonds and contingent capital), or statutory when the trigger
is determined by the relevant authority.27
The key objectives of bail-in features are to increase the loss-absorption capacity of capital while containing thecosts of raising it. In addition, they are thought to reduce the funding advantage (moral hazard) of systemicallyimportant institutions by providing an additional statutory mechanism to the relevant supervisory authority to
impose losses on unsecured creditors before the point of non-viability and, hence, to stem financial contagion.
As such, they aim at eliminating one of the market imperfections invalidating the Modigliani-Miller theorem
that artificially reduces banks’ cost of funding and capital relative to insurers.
Key feasibility issues still need to be resolved if these objectives are to be achieved. To name a few: (i) the bailin regime could apply to only capital instruments or all non-equity liabilities, depending on the tradeoffs
between market discipline and cost of capital; (ii) the design of the conversion trigger is crucial in many
respects, since too high (low) a level trigger increases (reduces) market discipline but increases (reduces) cost ofcapital; (iii) so far, it is unclear whether a sufficiently high trigger would actually prevent contagion, especiallygiven the difficulty of accounting for cross-border problems and mobility of capital within a financial group;(iv) the investor base for bail-in instruments is undetermined, as it needs to be ex post fit and proper and able toabsorb the risk transfer without further fiscal or financial spillovers; (v) the pricing of these instruments isdifficult, especially in the neighborhood of the statutory non-viability determination, where an obvious
discontinuity is introduced; (vi) statutory bail-in features raise legal concerns regarding rights of claimants28 aswell as their hierarchy after the trigger is hit; (vii) accounting and tax treatment of bail-in instruments needs tobe defined; and (viii) finally, even if feasibility concerns are overcome, it is unclear that bail-in instruments
under Basel III would constitute any meaningful, practical advancement relative to the unsuccessful experienceof subordinated debt under Basel II.
Bail-in proposals for banks could have an ambiguous impact on potential regulatory arbitrage with insurers.
Their successful design and adoption are likely to, everything else being equal, strengthen market discipline,
improve resolvability and, hence, eliminate the capital and funding advantage of systemically-important banks
relative to insurers. In other words, bail-in instruments would increase the average cost of capital for banks andencourage risk to migrate from banks to insurers. Alternatively, if they prove as successful as subordinated debt
in imposing losses on unsecured creditors, then the cost of capital for banks could actually decrease relative toinsurers (see Section VI on unintended consequences).

27

Bail-in proposals are being discussed by the FSB Bail-in Group. They build on the contingent capital
initiatives and interests of countries like Canada, The Netherlands, United Kingdom, and the United States ofAmerica.
28

These in turn depend on the conversion rates determining the burden sharing between equity and non-equity
holders.

25
54.
Finally, Basel III is also considering bail-in capital proposals, the discussion ofwhich is less advanced in the context of Solvency II. The recent financial crisis has createda concern that governments were bailing out not only consumers but also investors, as they
assisted banks financially in order to avoid systemic failure. The use of contingent capitaland other hybrid instruments has been suggested as one way to help deal with such situationsin the future (Box 1). They can take a variety of forms, but are essentially debt instrumentsthat convert to capital under stressful conditions. They do not provide new funds in a stresssituation but only change the nature of the financial claim and its regulatory treatment. Theircomplexity could undermine the comparability of capital across sectors and potentially
impact risk taking by the entities, while their acceptance by investors is still uncertain.
Discussions regarding the possible use of contingent capital under Solvency II are lessdeveloped, perhaps as a consequence of the absence of agreement on the systemic relevanceof insurance entities (Geneva Association 2010 and CEA 2010) or perhaps because
reinsurance arrangements achieve already similar effects.
A. Loss-Absorption Capacity
55.
Under both accords, different tiers have different loss-absorption capacities. For
both Basel III and Solvency II, Tier 1 consists of capital that is fully loss-absorbent on agoing-concern basis and Tier 2 is capital that absorbs losses on a winding-up basis. However,
Solvency II also provides for a Tier 3, which consists of own funds other than Tier 1 andTier 2. The classification criteria under Solvency II include subordination, loss-absorbency,
permanence, perpetuity, and absence of servicing costs. Ancillary items that would convert toTier 1 capital, when called, are classified as Tier 2 AOF, while those that would convert toTier 2 capital are classified as Tier 3 AOF.
Common Equity Tier 1
56.
In both sectors, items of highest quality are eligible without limit toward meetingthe capital requirements. Basel III specifically identifies common equity as the highestquality subset of Tier 1 capital. Although the Solvency II Directive does not make a
distinction within Tier 1, the QIS5 technical specifications provide a list of items that cancount without limit in Tier 1. Basel III sets out 14 criteria that must be met in order for an
instrument to be included in CET, while Solvency II sets out only 5. The Basel III criteria are
more detailed than, but do not contradict, either the Solvency II Directive or the QIS5
technical specifications.
Additional Tier 1 Capital
57.
Under Basel III, additional Tier 1 capital refers to instruments that combine
both equity and debt characteristics. They can be included in Tier 1 in a certain proportionand under certain conditions. Basel III sets out another 14 criteria that must be met in order
for an instrument to be included in additional Tier 1 capital. For instance, instruments mustbe sufficiently loss-absorbent on a going-concern basis, which means that, among other26things, they need to be subordinated, have fully discretionary noncumulative dividends or
coupons, and have neither a maturity date nor an incentive to redeem. The innovative anddated hybrid instruments that were allowed under Basel II, are not allowed under Basel III.
58.
Under Solvency II, similar provisions apply. Under QIS5 technical specifications,
up to 20 percent of total Tier 1 capital can consist of paid-in capital instruments other thancommon equity. These instruments include preference shares, subordinated liabilities, andsubordinated mutual member accounts that meet specific criteria.
59.
Beyond these broad similarities, there are many differences in the detailed
criteria applied under the two accords. Some of the most significant differences relate topermanence, flexibility of payment, and loss absorption, as follows:Basel III does not allow dated instruments in Tier 1, while Solvency II allows 10-year
dated instruments. This difference could be justified by the matching of assets andliabilities in the insurance sector. Solvency II requires that the duration of the item becompared to the duration of the insurance and reinsurance obligations; and that any
redemption or repayment be subject to supervisory approval and be automaticallysuspended when there is a breach of the SCR.

Basel III prohibits a bank from exercising a call unless it either: replaces the
instrument with capital of the same or better quality at conditions that are sustainable
for the income capacity of the bank; or demonstrates that its capital position is well
above the minimum after the call is exercised. Solvency II does not impose a similar
requirement.



The Alternative Coupon Settlement Mechanism (ACSM, whereby a coupon is paid inshares if it cannot be paid in cash) is no longer allowed under Basel III, but is stillallowed under Solvency II.

Solvency II requires that coupons must be cancelled when there is a breach of the
SCR. Basel III does not explicitly require such cancellation.

Basel III requires that instruments accounted for as liabilities must have a lossabsorption mechanism, such as a write-down or conversion of principal, but
Solvency II does not.



Solvency II is more explicit than Basel III with respect to the mechanics ofconversion, for example, requiring that an item must convert automatically into
ordinary shares.



Solvency II specifies the trigger point as a significant breach of the SCR, while
Basel III does not specify the level of the trigger.

27
60.
Also, several insurance-specific items are included in Tier 1 capital under
Solvency II, but are not recognized as capital under Basel III. In certain jurisdictions,either law or an insurer’s by-laws may require that reserves be established, which can only be
used for prescribed purposes. Reserves of this nature are only eligible for inclusion in capitalin relation to the risks they cover. Also, surplus funds are deemed to be accumulated profits
which have not been made available for distribution to policyholders and beneficiaries.
Unless otherwise provided by law, surplus funds are not to be considered as insurance
liabilities and they would therefore be classified as Tier 1 capital.
61.
The most significant insurance-related item is the expected profits included infuture insurance premiums under in-force insurance policies. Under Solvency II,available capital reflects the difference between the market value of the assets and the market
value of the liabilities. The value of liabilities takes into account expected future insurance
premiums,29 even if the policyholder is not contractually committed to making the premium
payments, and therefore includes the future profits inherent in those premiums. This portionof the liabilities provides some loss-absorption capacity, which might be recognized ascapital.
62.
However, expected profits included in future insurance premiums are not always
fully recognized as capital. For example, both Solvency I and some individual jurisdictions,such as the United Kingdom, currently limit the extent to which future profits on insurance
policies that have guaranteed surrender values can offset losses on insurance policies. The
treatment of expected profits included in future insurance premiums under Solvency IIremains uncertain. EIOPA has expressed the view that expected profits included in futurepremiums should be classified in Tier 3, because this item does not possess thecharacteristics necessary to be considered as Tier 1 or Tier 2 capital. However, the EC
decided to classify this item as Tier 1 for QIS5 purposes. The amount of expected profits
included in future premiums has been tested under QIS5 and the classification is expected tobe revised.
63.
Banks also recognize the expected profits included in future cash flows ascapital, but only if such cash flows are contractually committed. The treatment of
expected profits for insurance policies in force is similar to, but goes beyond, the manner inwhich contracts with expected future cash flows are dealt with under Basel II and Basel III.
For example, trading in market instruments such as interest rate swaps is accounted for at fair29

For example, with a regular premium endowment insurance policy, the policyholder might be committed to
paying future premiums, but might be able to surrender the policy or make it paid up (in other words, stop
paying further premiums, with insurance coverage continued at a lower amount). In other types of policies, thepolicyholder might not be contractually committed to make further premium payments, but might have a regular
history of doing so, and might therefore reasonably be expected to do so at least for a while going forward.

28
value, thus recognizing the future profits inherent in such contracts. However, in the banking
sector, all such future cash flows are contractually committed.
64.
Finally, the bases used to calculate the limits on additional Tier 1 capital differ
by sector. Under Basel III, limits are based on the amount of CET, which means that if CETdecreases when losses occur, the eligible amount of additional Tier 1 capital also decreases.
Under Solvency II, limits are based on the amount of the SCR. However, in both cases any
capital in excess of the limits is not counted within any part of regulatory capital.
Tier 2 and Tier 3 Capital
65.
The main differences with respect to Tier 2 capital are in the criteria related topermanence. Basel III does not allow any incentives to redeem, such as step-ups, while
Solvency II allows incentives to redeem after five years. However, Solvency II would deem a
step-up associated with a call to be equivalent to a maturity date. Under Basel III, recognitionin eligible Tier 2 will be “amortized” on a straight-line basis during the final five years tomaturity, while Solvency II does not require amortization. However, under Solvency II thelock-in clause would prevent repayment if this would lead to breach of the SCR.
66.
Again, many insurance-specific capital items are not recognized under Basel III.
As is the case for Tier 1, several items that are included in Tier 2 or Tier 3 capital under
Solvency II, are not recognized as capital under Basel III. They consist of the following
items:


Called-up but unpaid capital is included in Tier 2 basic own funds (BOF), which isjustified by the long time horizon of the insurance business;Unpaid capital and not called-up share capital are included as part of AOF;



Any future claims that mutual or mutual-type associations with variable contributions
may have against their members, by way of a call for supplementary contributions
within the following 12 months, are included in Tier 2 AOF;



Any future claims that mutual or mutual-type associations of ship owners withvariable contributions solely insuring risks to ships (sea, lake, and river and canalvessels), liability for ships (sea, lake, and river and canal vessels), and the legal
expenses and costs of litigation may have against their members, by way of a call for
supplementary contributions within the next 12 months, are included in Tier 2 AOF;
and



Letters of credit (LOC) and guarantees that are provided by authorized credit
institutions and held in trust for the benefit of insurance creditors by an independent
trustee, and are currently being used to meet solvency requirements under Solvency I,

29
and included in Tier 2. Other LOC that generate capital once called up can be
included subject to prior supervisory approval.


The treatment of the provisions included by Basel II in Tier 2 under the standardized
and internal ratings-based approaches to credit risk, including the treatment of the cap(in other words, the 1.25 percent and 0.6 percent of credit risk-weighted assets under
the SA and IRB approaches, respectively) is still to be considered.
B. Regulatory Adjustments to Capital

67.
Substantial differences exist in the regulatory adjustments to capital allowed
under both accords (Table 2). Basel III strengthens the standards for regulatory adjustments
relative to Basel II. Under Basel III, deductions and prudential filters (“regulatory
adjustments” or “capital deductions”) are mainly applied at the level of CET or sometimes atthe level of other tiers. Solvency II also considers regulatory adjustments to Tier 1 or Tier 2
depending on the instrument.
68.
Some of the differences arise from differences in the underlying valuation
principles rather than real differences in what is considered capital (Table 2). If an item
is given no value under the fair-value approach required by Solvency II, it has the same
effect as deducting its value under Basel III. For instance, investments in own shares are notdeducted under Solvency II because common equity is only included on a net basis to begin
with. Also, it is not necessary to deduct goodwill under Solvency II, because it is notconsidered an identifiable and separable asset, so it is assigned no value. Finally, own credit
risk is not considered when valuing financial liabilities under Solvency II, so changes in own
credit risk do not create gains or losses.
69.
However, seemingly inconsistent differences do exist in the treatment of several
items (Table 2).30 For instance, the deduction of intangible assets other than goodwill, suchas software, under Basel III recognizes that in periods of stress those assets are likely to havelittle value. Under Solvency II, although this risk should be recognized by a risk surcharge
when calculating the SCR, there is no requirement that this portion of the SCR be covered bya specific type of capital. Similarly, under Basel III, deferred tax assets resulting from tax
loss carried forward are fully deducted, while DTA resulting from timing differences are
deducted above a certain threshold. Under the Solvency II QIS5 technical specifications, nosuch differentiation is made and the net DTA are deducted from Tier 1, but classified as
30

In the Basel agreement, regulatory adjustments were bitterly fought out as, globally, there is considerable
variation in terms of composition of capital and reliance on capital elements that can be unique to a region.
Even within the EU strong differences emerge. For instance, pension liabilities are an important item for UK
banks, while participation in insurance subsidiaries is critical for French banks. Finally, different tax regimes
have guided many of the regulatory adjustments in the Basel accord (and presumably, in the Solvency II
framework.)

30
Tier 3 BOF. Also, employee-defined benefit pension fund assets and liabilities are excluded
when calculating capital under Basel III, but not under Solvency II. Solvency II in effectassumes that an excess of assets over liabilities would be available to meet other obligations,while Basel III in effect assumes that the rights of employees might prevent this.31 In
addition, Basel III requires that the premium attached to any shares excluded from CET also
be excluded from CET, and instead be included in the same Tier as the shares to which they
relate. Solvency II does not indicate such treatment. Finally, the treatment of equity
investment in financial entities and the methods used to apply regulatory adjustments aredifferent under the two accords. 32
70.
Finally, Basel III and Solvency II use different methods to apply regulatory
adjustments to capital at a group level. In the banking sector, deductions are appliedfollowing the “corresponding deduction approach.” In other words, a deduction would beapplied to the same component of capital for which the capital would qualify if it was issued
by the bank itself. In the insurance sector, deductions are applied following the “deduction
and aggregation” method. In other words, after the participation is deducted from theparticipating entity’s own funds, capital requirements and own funds of the participatedentity are added proportionally to the ones of the participating entity. The method used in thebanking results in a smaller transfer of resources from the participated to the participating
entity. Hence, it is more prudent when the participated entity is in surplus, but it is lessprudent when the participated entity is in deficit.

31

Since surpluses are recognized as assets, Solvency II requires capital in their respect because the total balance
sheet is shocked.
32

Admittedly, standards under Basel III are more stringent than under Basel II. Under Basel II, the generalprinciple that double gearing was to be avoided appeared weakly enforced. Provisions for investment ininsurance subsidiaries required (a) full deduction of participations when this was less than 50 percent of theinsurance subsidiary capital; or (b) full deduction of participation only up to the minimum capital requirementof the subsidiary when participation is above 50 percent of the insurance subsidiary capital (i.e., surplus capitalcan be recognized and risk weighted as an equity investment). In any case, ample discretion was left to theauthorities to apply alternative group-wide approaches suggesting that, in practice, deductions were low. A
different treatment applied to participations in banks. The more stringent Basel III standards prompted many
European banks with important participation in insurance subsidiaries to lobby fiercely for a more favorable
interpretation of rules by the EC. More on this point in Section VI, where we discuss unintended consequences
related to the cost of capital.

32
C. Implications
71.
The difference in criteria used to determine capital eligibility of instruments
impacts on the relative cost of capital. Both sectors have access to the same capital markets
for raising funds, so differences in the criteria used to determine the eligibility of an
instrument as regulatory capital might lead to differences in the cost of capital and regulatory
arbitrage across sectors. In addition, the treatment of various types of claims, such as those of
consumers and providers of various forms of capital—including reinsurers, under winding-up
legislation—could affect the availability and cost of capital.
72.
Also, the differences in regulatory adjustments to capital and their methods ofapplication impact on the relative cost of capital. The higher threshold for defining
significant participations (20 percent under Solvency II and 10 percent under Basel III)
appears to suggest a larger scope for double gearing under Solvency II than Basel III.33 In
addition, the method used under Solvency II can result in a higher variance of the solvency
position of the participating entity. If this translates into a higher risk-adjusted expected
profitability, then the cost of capital should be lower than for the banking sector (other things
being equal).
V. PILLAR 1: REQUIRED CAPITAL
73.
Both Basel III and Solvency II prescribe risk-based approaches for determining
the amount of capital that is needed to support an entity’s business. The details of eachaccord are complex and include various alternatives, such as the use of standardized
approaches or internal models. This section examines key aspects of the determination ofrequired capital, focusing on differences between the standardized approaches of the two
accords.
A. Overall Methodology
Basel III74.
Basel III continues the same overall methodology as Basel II for determining
required capital. The aggregate level of risk of a bank is expressed in terms of an equivalentamount of risk-weighted assets, with required capital being expressed as a percentage of thetotal risk-weighted assets. The calculations of risk-weighted assets are performed separately
for each of the three main areas of risk: credit risk, market risk, and operational risk. The

33

More specifically: (i) a holding between 10 percent and 20 percent is deducted when the holder is a bank andnot deducted when the holder is an insurer; and (ii) a holding in an insurer of less than 10 percent with nosignificant influence but representing more than 10 percent of the participating entity’s common equity is
deducted when the holder is a bank but not deducted when the holder is an insurer.

33
results are added together, without adjustment for possible correlations, to arrive at the totalrequirement.
75.
Standards for defining minimum capital requirements are also maintained, but
considerably strengthened. Basel III continues not to explicitly specify a supervisory
control level of capital in probabilistic terms like Solvency II. However, as mentioned in
Section IV, it does establish requirements for the minimum levels of both CET and total
capital, and it introduces a capital conservation buffer. These requirements serve similar
purposes to the “probability of ruin” for insurers in differentiating the level of capitalrequired of a going concern from that of a gone concern and providing a basis for earlysupervisory intervention. Important modifications include a more stringent minimum
common equity capital ratio and the introduction of a capital conservation buffer, acountercyclical buffer, a nonrisk-based leverage ratio, and additional requirements for
systematically-important banks:The required ratio of CET to risk-weighted assets will increase from 2 percent to
4.5 percent by January 1, 2015, and will also incorporate stricter regulatory
adjustments.



The required Tier 1 capital ratio, which includes common equity and other qualifying
financial instruments, will increase from 4 percent to 6 percent over the same period.
The minimum ratio of total Tier 1 and Tier 2 capital to risk-weighted assets willremain at 8 percent.

A capital conservation buffer of 2.5 percent, which will be phased in between 2016
and 2019, is to be met with common equity.

A counter-cyclical capital buffer, within a range of zero percent to 2.5 percent ofcommon equity or other fully-absorbing capital, will also be required if national
circumstances show excess credit growth and system-wide risk.

76.
Banks can use either standardized approaches or internal models fordetermining minimum required capital. The standardized approach34 produces riskweighted assets in a standardized and predefined manner, supported by external credit
assessments.35 The internal ratings-based approach (IRB) can be used with prior supervisory34

For operational risk, banks are also allowed to use the simpler (than the standardized approach) basic
indicator approach where the capital requirement is simply a multiple (15 percent) of the average of theprevious 3 years of annual gross income.
35

In determining the risk weights under the standardized approach, banks may use assessments by external
credit assessment institutions recognized as eligible for capital purposes by national supervisors in accordancewith predefined criteria.

34
authorization and it is based on either only internal models or partially internal models andsupervisory-provided risk factors. For market risk, banks must compute exposures based on
the value at risk (VaR) model with a 99 percent (one tailed) confidence interval over a
10-day holding period on the basis of historical observations of a minimum one year. For
credit risk, computation of exposures (both systematic and idiosyncratic) is based on theasymptotic single-risk factor (ASRF) model with a 99.9 percent confident interval andexpected losses forecasted over a one-year horizon. For operational risk, the advanced
measurement approach36 (AMA) sets the regulatory capital in line with the results of thebank’s own operational risk-measurement system on the basis of a VaR model with a
99.9 percent confidence interval over a one-year horizon.37
77.
While discretion exists to require higher risk weights, the IRB approach has
resulted in lower risk weights. Supervisors can require higher risk weights under Pillar 2than those provided for by the standard setter under Pillar 1, but this has seldom been done.
Instead, the fundamental choice of Basel II was to promote the adoption of the IRB approach,which was designed to provide, on average, lower risk weights than those provided for under
the standardized approach, as a way to promote risk-management capacity among banks.
78.
Basel III also introduces new requirements to contain leverage and liquidity
risk. The leverage ratio compares capital to non risk-weighted assets.38 It was set at 3 percent
in July 2010 and the BCBS agreed to test that minimum during a parallel-run period startingin 2013. Based on the results, any final adjustments will be carried out in the first half of2017, with a view to moving to full Pillar 1 treatment on January 1, 2018. The net stable
funding ratio (NSFR) measures how much stable funding a bank has to endure during a yearlong liquidity crisis. It complements the shorter-term liquidity coverage ratio (LCR).
79.
Basel III strengthens the computations of market risk for extreme value events.
For extreme value events, banks will now have to calculate a stressed VaR based on a
10-day, one sided 99 percent confidence interval. The stressed VaR needs to be calibrated toa period of significant and relevant financial stress that entails many degrees of freedom incalibration for the bank. The maximum of the stressed VaR and its average of the preceding
60 days (multiplied by 3) is to be added to the general capital charge. Additionally, thecurrent specific risk charge (which will be subject to updates) continues to be required.
36

This is the IRB equivalent allowed for credit risk.

37

See Kemp (2009) and Appendix I and II for details on calculations and capital requirements for different
types of risk.
38

For off-balance sheet items, uniform credit conversion factors will be applicable. Derivative exposures will becalculated by applying existing Basel II netting rules, along with a simple measure of potential future exposure
based on the standardized factors of the current exposure method. The leverage ratio will be calculated as anaverage over a quarter.

35
80.
Finally, Basel III requires additional charges for systemically importantfinancial institutions (SIFIs). In June 2011, the BCBS, together with the G20 and the FSB,
agreed that larger banks would be subject to a capital surcharge ranging from 1 percent to
2.5 percent to be met through common equity and not through hybrid instruments. Such arequirement will be complemented with enhanced supervision. The purpose of introducing
these additional measures would be to mitigate the risk that SIFIs pose to the local and global
financial systems.
Solvency II
81.
Solvency II uses both absolute and risk-based minimum capital requirements.
As a start, there are different minimum absolute capital requirements depending on the natureof an insurer’s business: EUR 1 million for a captive insurer; EUR 2.2 million to
EUR 3.2 million for a nonlife insurer, depending on the classes of business written; andEUR 3.2 million for a life insurer or a reinsurer. There are then two risk-based levels ofcapital requirements: the MCR, representing the level of capital below which an insurer
would be considered a gone concern, and the SRC, the level of capital required of an insurer
to be considered a viable going concern, both introduced in Section IV.
82.
The MCR and SCR are closely related and calibrated over a one-year horizon.
The risk measure used under Solvency II to calibrate these requirements is value at risk
(VaR) with the MCR calibrated at 85 percent VaR over one year, while the SCR is calibrated
at 99.5 percent VaR over one year. Further work will be done on the calibration of risk
parameters in areas such as nonlife underwriting risk and catastrophe risk in response to theresults of QIS5. The SCR should always be higher than the MCR, but because they arecalculated differently, this might not be the result. To deal with this possibility and to allow
the SCR to serve as a control capital requirement, Solvency II caps the MCR at 45 percent of
the SCR; it also establishes a floor for the MCR of 25 percent of the SCR. However, the
MCR is subject to the aforementioned minimum absolute amounts, which, for a small
insurer, might even be higher than 45 percent (or even 100 percent) of the SCR, thus
overriding the cap. Finally, the MCR must be met by the eligible BOF of the insurer, while
the SCR can be met by all eligible capital, including AOF.
83.
Insurers can use either a standardized approach or internal models to calculate
the SCR. The use of internal models follows a principles-based approach. Full internal
models can be used or partial internal models can be used in combination with the standard
formula. In either case, their use is subject to supervisory approval. Supervisors can impose
capital add-ons to the SCR if they consider the risk profile of an insurer to be higher than that
contemplated in the standard formula or if the internal model is not fully adequate.
84.
Also, calculation methodologies vary by type of capital requirement. On the one
hand, MCR calculations are not done on a per-risk basis, although such capital is intended tocover all risks to which an insurer is subject. Instead, risk factors are applied to various

36
components of an insurer’s premiums and liabilities. The calculations are linear and therefore
do not take account of diversification effects or risk interdependencies. On the other hand,
the SCR is calculated on a per-risk basis covering nonlife underwriting risk, life underwriting
risk, health underwriting risk, market risk, counterparty default risk, and operational risk.39
Scenarios are mostly used under the standard formula (for which they are required) and theinternal models (for which, however, they are not required) to determine the required capitalby assessing the effects that adverse future experience would have on the financial positionof the insurer. In addition, calculations are prospective, as they include not only the existing
portfolio of business, but also the new business an insurer expects to write during the next
12 months (although there is some uncertainty about how the new business requirement is tobe applied). Finally, calculations are not linear, as they also take account of diversificationand interdependencies.
85.
Finally, capital requirements are recalculated frequently and insurers are
subject to stress tests to ensure solvency. The MCR must be calculated quarterly. The SCR
must be calculated yearly, although recalculation is also required whenever the risk profile ofan insurer changes significantly. The period of historical data required to support thecalculations is not specified, but the models should be recalibrated when Own Risk andSolvency Assessments (ORSAs) are performed. ORSAs serve several purposes, such as
assessing overall solvency needs, comparing the risk profile to that underlying the SCR
standard formula, and testing the ability to meet the SCR. However, the results of ORSAs are
not themselves used to calculate the SCR.40
B. Risk Aggregation and Dependencies
86.
Despite the modifications to the Basel accord, risk weights under Pillar 1 still
depend on portfolio invariance. This does not reflect the importance of diversification as an
influence on portfolio risk, nor does it adequately penalize concentrations in the portfolio by
requiring additional capital, which can instead be imposed by the supervisor under Pillar 2.
87.
However, credit risk mitigation (CRM) techniques are recognized when
determining required capital under Basel III. They include the use of (i) collateral;(ii) guarantees; (iii) credit derivatives; and (iv) claims netting.41
88.
Collateral posted by a counterparty or by a third party can hedge credit
exposures, either fully or partially. Banks can choose between two approaches: the simple
39

Details on capital requirements for these types of risks are discussed in Appendix II.

40

In other words, ORSAs assist in making sure the models are working properly and that the SCR will be
sufficient under stress. However, the SCR is calculated independently of the ORSA.
41

Credit risk mitigation techniques are also recognized under the IRB approach of Basel III.

37
approach or the comprehensive approach. Under the simple approach, banks can substitutethe risk weight of the collateral for the risk weight of the counterparty, subject to a 20 percent
floor. Under the comprehensive approach, they can reduce the risk weight of the counterpartby the risk weight ascribed to the collateral. In doing so, they are required to adjust both theamount of the exposure to the counterparty and the value of any collateral, using haircuts,and to take account of future fluctuations in either.
89.
Third-party guarantees or credit derivatives can be used to reduce credit
exposure when they are direct, explicit, irrevocable, and unconditional. Supervisors mustalso be satisfied that banks fulfill certain minimum operational conditions relating to riskmanagement processes and the guarantors must be recognized by the supervisor. In suchcases, the hedged portion of the exposure is assigned the risk weight of the guarantor orprotection provider.
90.
Credit risk mitigation (CRM) techniques can give rise to maturity mismatches.
Where there is a maturity mismatch and the CRM has an original maturity of less than one
year, the CRM is not recognized for capital purposes. In other cases, where there is amaturity mismatch, partial recognition is given to the CRM for regulatory capital purposes.
91.
On-balance sheet netting can be allowed if risk-management processes meetcertain operational conditions. In particular, a bank needs to be able at any time todetermine those assets and liabilities with the same counterparty that is subject to the netting
agreement. In such cases, assets (loans) are treated as exposure and liabilities (deposits) as
collateral. The haircuts will be zero except when a currency mismatch exists.
92.
Under Solvency II, diversification effects and risk interdependencies arereflected in the standard formula for SCR using correlation matrices. Adjustments areapplied at various levels: within the same risk class and business line; within a risk class andacross business lines; across risk classes; and at a group level. For example, the correlations
across risk classes are based on the matrix shown in Table 3. The application of correlations
can reduce the requirements significantly, compared to a linear combination.

93.
Concentrations affect the calculation of required capital in several risk modules
or sub-modules. Underwriting risk concentrations are recognized in the nonlife catastropherisk and life catastrophe risk sub-modules. Additional risks to an insurer stemming either
from lack of diversification in the asset portfolio or from large exposure to default risk by asingle issuer of securities or a group of related issuers are recognized in the market risk
concentrations sub-module. The counterparty default-risk module takes account of theoverall counterparty risk exposure of the insurer to that counterparty, irrespective of the legal
form of its contractual obligations to the insurer.
94.
All types of risk-mitigation contracts are recognized under Solvency II. They
include reinsurance, securitizations, and derivatives. The counterparty default risk module
takes account of the related risk that arises from such contracts.
C. Scope for Consolidation
95.
Basel III is applied to either the solo entity or the consolidated group up to theholding company. The scope of application has not changed from Basel II and includes:(i) any holding company on a fully consolidated basis within a banking, or a predominantly
banking, group; (ii) all internationally-active banks at every tier within a banking group, also
on a fully-consolidated basis. For bank conglomerates (i.e., groups with prevalently abanking activity but also containing other financial entities), the holding company bears thefull entrepreneurial risk of the subsidiary, which is recognized at the group level andsupervisors assess the appropriateness of recognizing the participation. In general, when notconsolidated, full deduction is required.42 Finally, the same methodology to calculate capitalrequirements is applied to either the solo or group level.
96.
Group-level calculations of required capital under Solvency II focus on thegroup SCR. Although an approximation of “group MCR” is calculated by summing up the
MCRs of the separate legal entities; the purpose of this calculation is just to establish a floor
for the group SCR. Solvency II describes two basic methods for calculating the group SCR.
Method 1, which is the default, is accounting consolidation. The standard formula for
calculating the SCR is applied to the consolidated assets and liabilities of the group.
Method 2, which is an alternative, is deduction and aggregation. The solo SCR and solo
capital for the insurers in the group are combined, using a proportional basis for insurers thatare not wholly owned. Where the exclusive application of Method 1 would not be
42

Under Basel II, it was appropriate to deduct banks’ equity and other regulatory capital investments ininsurance subsidiaries as well minority investment in insurance entities. With Basel III, the treatment ofparticipation in insurance subsidiaries within the group has been aligned with the treatment of other financial
enmities (see previous section on capital deduction). However, risk aggregation is still subject to alternative
approaches with some countries retaining their existing risk weighting treatment and on a consistent basis tothat applied by insurance supervisors for insurance firms with banking subsidiaries.

39
appropriate, groups can apply a combination of Methods 1 and 2. Internal models can also be
used to calculate group SCR. Diversification of risks across entities within a group isreflected in the calculations, except under Method 2.
97.
Generally, Solvency II rules must be applied when making calculations in
respect of insurers that are based outside the EEA. However, if the solvency regime of a
non-EEA jurisdiction is assessed as equivalent to Solvency II, then the solo SCR and solo
capital of insurers based in such jurisdictions, determined under local rules, can be used in
the group calculations when method 2 is used.
98.
Where members of a group are other types of regulated financial institutions,the relevant sectoral requirements are applied under either Method 1 or Method 2.
D. Supervisory Responses to Breaches of the Capital Requirements
99.
An important role of capital requirements is to serve as a trigger for supervisory43
action. The imposition of minimum required capital and other control measures by theinternational standard setters and national authorities raises the need for supervisors to adopt
structured systems for responding to breaches of such requirements.
100. In the banking sector, such systems take various names. They include Prompt
Corrective Action (PCA, used in the United States) and Structured Early Intervention and
Resolution (SEIR, used in some Asian and European countries). In general, these systems
seek recovery or orderly resolution of institutions and to minimize deposit insurance losses inrespect of those that do fail. For example, the PCA classifies banks under five categories andidentifies appropriate supervisory responses for each. The five categories are: wellcapitalized, adequately capitalized, undercapitalized, significantly undercapitalized, andcritically undercapitalized. The last category includes those banks with tangible equity capital
below 2 percent of total assets. Under PCA, supervisory actions can be summarized asfollows:

Undercapitalized banks must have permission from the supervisory authority in orderto pay dividends or make stock repurchases.



Undercapitalized banks must submit a capital restoration plan, which must be
approved by the bank’s supervisor.



Significantly undercapitalized banks must limit bonuses and salary increases to the
management.

43This approach is common in insurance supervision but less so in banking.

40

Critically undercapitalized banks must be placed in receivership within 90 days if noother option is available.

Supervisors can also take additional actions to help prevent further losses, such aschanging management.

101. Basel III and the European Capital Requirements Directive (CRD) bothemphasize the need for timely supervisory intervention when banks fail to meet capitalrequirements. Both require a review and examination of banks’ risk profiles andmanagement systems and demand prompt application of prudential measures. However,supervisory intervention is not detailed as under the PCA of the United States. Also,supervisory powers and compliance differ from country to country. For instance, limited
information and limited legal powers to intervene may hinder supervisors in some countries.
102. Under Solvency II, breaches or expected breaches of the capital requirements
must be notified to supervisors. An insurer must notify its supervisor as soon as it observes
that the SCR has been breached. Within the next two months, the insurer must submit a plan
for achieving compliance within a period of six months. The period for achieving compliancecan be extended by three months—or longer in the event of a significant fall in the financial
markets. Similarly, an insurer must notify its supervisor as soon as it observes that the MCR
has been breached or where a breach is likely within the next three months. In this case,however, the timeline for remediation is shorter. The insurer has one month to submit a planand three months in which to achieve compliance, either by obtaining additional capital or
reducing its risk profile. During the period of noncompliance, the insurer may be restricted inor prohibited from disposing of assets.
103. Finally, insurers are required to disclose breaches of the capital requirements.
Information on SCR coverage is required to be publicly disclosed by insurers and that they
announce publicly if their SCR coverage falls below 100 percent, along with the reasons why
this happened and any remedial actions taken. Furthermore, for capital instruments to qualify
as Tier 2 or better under Solvency II, they must permit deferral of payments if SCR coverage
falls below 100 percent. It is therefore likely that insurers will seek to maintain sufficient
capital to minimize the risk of breaching the SCR.
E. Implications
104. It is very difficult to compare capital requirements under the two accords. The
methodologies and risk categories differ, so comparisons made at the level of a transaction orbusiness portfolio might not be valid in the context of the entity as a whole. For example, therequirements under Solvency II reflect correlations among the main risk areas while therequirements under Basel III treat each main risk area separately. As another example, a bankand an insurer might each hold the same type of loan asset in support of their respective
liabilities. Therefore, the capital required in respect of the credit risk associated with that41
asset can be compared. If the bank is holding the loan in its banking book, no additional
capital is required in respect of the related deposit liability. However, an insurer would also
be required to hold capital in respect of the insurance risk on the related policies.
105. It is very likely that some similar risks have different capital charges under thetwo accords. The different natures of the basic approaches to calculate capital requirements,
the differences in credit-mitigation techniques (aggregation and dependencies), as well as theinherently ad hoc nature with which capital standards have been negotiated, are likely44 toresult in different capital requirements for similar risks.
106. Finally, the promotion of internal models under Solvency II requires carefulconsiderations. Similarly to Basel II, the promotion of internal models under Solvency IIaims at strengthening risk-management capacity among insurers. However, with Basel II, theIRB approach was calibrated to produce on average lower risk charges than those provided
for by the standard approach. International experience has shown that the ratio of RWA overtotal assets has, on average, decreased for a large set of European banks (Yogarajah, 2011).
In other words, either banks have progressively found innovative ways to inflate their capital
adequacy ratios or supervisors have progressively relaxed, maybe unintentionally, validation
standards. The experience with internal models under Basel II should provide importantlessons for insurance supervisors and promote close collaboration in this area between
regulators in both sectors.45
VI. UNINTENDED CONSEQUENCES OF THE TWO ACCORDS
107. The joint implementation of the two accords could lead to unintended
consequences. The largely independent development processes of the two accords anddifferences in their content could lead to unintended consequences. In this section, we focus
on (i) cost of capital; (ii) funding patterns and interconnectedness; (iii) product and/or risk
migration; and (iv) other potential sources of arbitrage.46

44

Clearly, this would require empirical confirmation which, to our knowledge, is yet to be produced.

45

The definition of the internal model framework, test and standards under Solvency II, is already set out in the
Solvency II Directive and has been based on large extent on the experience of banking models under Basel II.
Further collaboration will be needed in the supervisory assessment of the models.
46

As we will, the extent with which these are source of concern is a matter of empirical investigation that isbeyond the scope of this paper.

42
A. Cost of Capital
108. It is unclear whether, and if so, to what extent the cost of capital for banks isgoing to increase compared to the cost of capital for insurers.47 The natural framework toconceptually assess the impact of the new accords on total cost of capital is the ModiglianiMiller theorem. However, not in terms of its overall validity but in terms of the market
imperfections which invalidate it, especially in the short run. These are debt interest
deductibility, moral hazard, asymmetric information, safety nets, bankruptcy costs, and debt
overhang (Jaffee and Walden, 2010). Since these imperfections are not necessarily equallyimportant for banks as they are for insurers (as explained later), Basel III and Solvency II
will have a different impact on the relative costs of capital. In addition, there are accord- andsector- specific arguments (many reviewed in the previous sections) for why the total cost ofcapital could increase more for one set of intermediaries than for the other more than what isrequired by their different risk profiles.
109. A first set of arguments in support of higher costs for banks relates to the
Modigliani-Miller theorem. For instance, banks benefit more from debt interest
deductibility to reduce their total cost of capital simply because they are more leveraged.
Hence, the debt-equity swap (i.e., deleveraging of banks) that Basel III tries to achieve, willraise the marginal cost of capital for banks more than for insurers. Regarding moral hazard,
the same difference in leverage suggests that a debt-equity swap will increase the total cost ofcapital for banks more than for insurers as there is now less debt that can be used as amonitoring device for bank managers.48 Along the same lines, a reduction of the too-big-tofail (TBTF) funding benefit enjoyed on average more by banks than by insurers could lead tohigher average cost of capital for banks. Regarding information asymmetries, Solvency II
and Basel III are different information events. The former possibly signals insufficient capitallevels (in addition to quality) in relation to the recent shocks, while the latter signals only
inadequate quality (rather than levels, and not necessarily in relation to recent shocks).
Hence, higher total capital costs could result for banks than for insurers.49 Finally, regarding
safety nets, these are often subsidized guarantees, the value of which depends on thelikelihood of bankruptcies. To the extent that Basel III reduces the relative likelihood of

47

Notice that the concern is not about the higher capital requirements (and costs) for banks. Indeed, this is oneof the intended consequences of Basel III. The concern is more about the change in the cost of capital for banks
relative to insurers in excess of the full recognition of risks as this could yield unintended risk transfers acrossthe two sectors.
48

The corporate finance literature suggests that debt holders monitor the behavior of managers as, contrary toequity holders, cannot bet on the residual value f the firm. There is a debate on the importance of debt as amonitoring device.
49

The opposite can be argued of course as seen later.

43bankruptcy for banks (i.e., more than what Solvency II does for insurers)50 the relative benefit
from these subsidized guarantees is also reduced more for banks.51
110. A second set of arguments in support of higher costs for banks relates to specificdifferences in the two accords or sectors.
For instance, the larger scope for risk-mitigation techniques allowed for under
Solvency II (including the use of reinsurance) could result (other things being equal)
in a lower cost of capital for insurers than for banks.

Similarly, the retrospective valuation methodology of banks could decrease (increase)the cost of capital for banks in the high (low) part of the cycle relative to insurers,
which use a more prospective (and potentially volatile) methodology.



In addition, capital deductions appear more stringent under Basel III than Solvency II.
A case in point are intangible assets (other than goodwill), which are deducted under
Basel III, but not under Solvency II. In particular, investments in software, which aremeant to comply with regulations and gain efficiency.

Also, banks’ capital costs for hedging since insurance companies will be encouraged
to take long-dated swaps contract to hedge their risks under Solvency II, but Basel III
will require banks to hold more capital (and collateral) against these positions. Thissuggests that hedging will become more expensive for banks and they will be lesswilling to hold long-term interest rate swaps that insurance companies find so useful.

The more restricted geographical application of Solvency II could result in serious
leakage problems, with insurers “lowering” their capital charges by using reinsurers
in jurisdictions with solvency standards deemed equivalent by the EC but thatde facto are non-equivalent (more lenient).52And again, bank regulators are likely to agree on additional step-up capital surcharges
for systemically-important banks, as a function of their size, interconnectedness, and

50

Whether Basel III reduces the likelihood of bankruptcy for banks more than Solvency II for insurers (i.e.,with a probability lower than 1 in a 200 year stress) is naturally a matter of empirical investigation.
51
52

In addition, safety nets cover on average a larger portion of banks’ liabilities than of insurers’.

There is a debate regarding the extent to which leakages could be a problem. It all depends on the way inwhich reinsurance receivables are valued and on the capital that insurers would be required to hold to protect
against the risk of the reinsurers defaulting on their promises. Hence, this problem could be obviated by a
responsible determination of equivalent jurisdictions by the EC and/or by requiring higher counterparty capitalcharges for exposures in non-equivalent jurisdictions. The issue, while discussed, has yet to be resolved within
Solvency II.

44substitutability, which would conceptually be difficult to apply to large insurers.
Indeed, given the nature of the insurance business, size is associated with increased
risk diversification and a priori not warranting higher capital charges.
Along similar lines, insurance liabilities are more loss absorbing than banks and this
could reduce, other things being equal, insurers’ cost to raise additional capital.



Solvency II is explicitly promoting the use of internal models, which are expected toprovide 30–40 percent capital requirement reductions relative to the standardized
model.53 This provides the sector with ample scope to reduce cost of capital relative
to banks in a period when regulators are instead discovering that bank RWA havebeen progressively eroded relative to total assets (Yogarajah, 2011).

Finally, there is great uncertainty on the impact of capital levels for insurers
stemming from the yet-to-be-defined treatment of the illiquidity premium in valuing
liabilities.54

111. On the other hand, there are arguments in support of a higher cost of capital for
insurers.


In general, the move to a more risk-based approach is likely to increase the cost ofcapital for the riskier insurers, as investors use the additional information to seek out
higher quality insurers.

Regarding information asymmetries, the adoption of Solvency II (relative to
Solvency I) could be perceived by the markets as a more fundamental change than the
adoption of the Basel III proposals (which are merely incremental, relative to theBasel II accord).55

In addition, if insurers also try to achieve higher capital levels by reducing
liabilities,56 they are likely to do so at higher costs than for banks. Indeed, andcontrary to banks, there are no markets for many insurance liabilities (think of the53

In addition to this point, there is a need to factor likely changes to the correlation matrix used for QIS5.

54

The premium is likely to be substituted by a countercyclical premium that will be zero in normal market
conditions and only positive in stressed market conditions determined and calculated by EIOPA. Hence,
providing limited scope for reducing capital requirement for insurers relative to banks.
55

Following this argument, and the same terminology used in this sub-section, Solvency II would be an eventwith more “informational content” than Basel III.
56

For some jurisdictions, QIS5 results suggest an important reduction in technical provisions and the need toraise additional capital.

45
difficulty of hedging longevity risk, for instance) making the Modigliani-Miller
theorem less applicable to insurers than to banks.
Along the same lines, deleveraging of banks as a consequence of Basel III would
reduce bankruptcy costs more than for insurers and, therefore, reduce their cost ofcapital.



Regarding debt overhang, deleveraging will reduce the amount of investment returns
that accrue to debt holders and, therefore, reduce the total cost of capital (as the sumof the remuneration of debt and equity holders).

Finally, contingent capital and other bail-in instruments proposed under Basel III may
not succeed in eliminating the TBTF advantage enjoyed by banks. In this case, theywould translate in an additional cheap source of capital for banks but not for insurers,
for which discussions about such instruments are less advanced.

112. But, in general, we have seen how Pillar 1 requirements across the two sectors
are too different to argue conclusively in either direction. In particular, the two accords
may have the impact of increasing the incentive to issue equity by insurers and banks atsimilar times. The joint implementation of the two accords may thus result in higher cost of
new equity for both sectors relative to a staggered implementation. It is therefore possiblethat the joint implementation of the two accords will generate relatively stronger incentives
for risk to migrate away from the two sectors57 than from one sector to the other. The key
policy question then becomes which part of the financial system (a priori less supervised andregulated) is likely to attract such risk.
B. Funding Patterns and Interconnectedness
113. Basel III and Solvency II could have unintended consequences on funding
patterns of banks. There is concern among policy makers and market participants alike thatthe two accords could jointly reduce the demand for banks’ long-term instruments whenbanks most need to issue them.
114. On the one hand, the demand for debt instruments is likely to change under
Solvency II. In general, insurers using the standardized approach for the SCR will becharged capital requirements through the credit spread risk module proportional to the rating
and duration of instruments held on balance sheet.58 This automatically makes longer-dated
57

Possibly through increased reliance on securitization by both sectors for funding purposes.

58

The charge factor in the spread SCR calculation penalizes insurers for investing in low-rated debt instruments
while the duration multiplier penalizes longer maturities (especially above 20 years) (Bourdeau (2009)). At thetime of writing, the capital charge for spread risk of bonds had been revisited and the proposal was pending
decision by the EC. It is likely that in the final Level 2 proposal the capital charge for long dated bonds would(continued…)

46
and or lower-rated private sector instruments (relatively) less attractive. In addition, EEA
sovereign bonds, bonds guaranteed by EEA states and supra-national agency anddevelopment bank bonds—as it stands now—carry a zero risk weight in the standardized
approach, irrespective of rating. Also, distortions exist between banks and real sector
corporate, since bank-covered bonds receive preferential treatment with lower charges.59,60
Finally, the increased issuance of covered bonds could have a negative impact on banks’ability to issue unsecured debt. This is because, with covered bonds, the amount of
unencumbered quality assets available in case of bank resolution for unsecured creditors
decreases. In summary, the duration multiplier penalizes long-term maturities in general,
potentially increasing the likelihood that insurance companies be mismatched and bear
reinvestment risk, and result in a preference for sovereign debt and short-dated and higherrated bank debt (especially covered bonds), relative to other corporates, and could reduce theability of banks to issue unsecured debt.
115. On the other hand, Basel III will affect the banks’ demand for and supply ofcertain types of debt. Under Basel III, banks’ senior unsecured bonds do not qualify for the
LCR while they qualify for the NSFR.61 Covered bonds and sovereign debt qualify for boththe LCR and NSFR.62 Hence, it is likely that banks’ demand for unsecured debt will decrease
while the demand for covered bonds and sovereign debt will increase. For similar reasons, it
is likely that banks’ supply of covered bonds will generally increase while the supply of
unsecured debt will increase only at longer maturities to meet the NSFR requirements. In
other words, Basel III liquidity provisions could promote a partial swap on banks’ balance
sheets between senior unsecured and covered bonds for funding purposes, as well as anincrease in issuance of senior debt toward longer maturities (5 to 10 years).
be reduced in comparison with short term bonds, since the relationship between capital charge-duration is nottotally linear. In other words the factor F will decrease with the time.
59

For this to happen, covered bonds need to meet the requirements defined in Article 22(4) of the Undertakings
for Collective Investments in Transferable Securities (UCITS) directive 85/611/EC; that is (i) the covered bondissuer must be a credit institution; (ii) covered bond issuance has to be governed by a special legal framework;(iii) issuing institutions must be subject to special prudential public supervision; (iv) the set of eligible coverassets must be defined by law; (v) the cover asset pool must provide sufficient collateral to cover bondholder
claims throughout the whole term of the covered bond; and (vi) bondholders must have priority claim on the
cover asset pool in case of default of the issuer.
60

The charge factor for AAA and AA bank-covered bonds is 0.6 and 1.1, respectively, and it compares
favorably with the charge factor of other credit securities. Notwithstanding this observation, there is a strong
lobby to reduce the charge factor for AA covered bonds to 0.6 on the basis of their lower volatility relative toother AA credit securities. This would also be in line with the Basel III standardized approach, where credit risk
and market risk charges for AAA and AA securities are the same (see Appendix I).
61

Notice that the NSFR will still be subject to a long observation period and probably to important changes.

62

Although, the two asset classes do not qualify to the same degree.

47116. However, there are also arguments that could make unintended consequences onfunding patterns less of a concern.


For instance, it is unclear if and to what extent the demand from insurers for longterm maturity instruments will actually decrease. The tradeoff between maturity
mismatches, capital charges, and the impact of the duration multiplier will likely be
different across entities with different structures of liabilities.



In addition, the preferential treatment of banks’ covered bonds under the standardized
approach of Solvency II suggests that rather than a decrease in demand for banks’funding instruments we might instead see only a change in the funding patterns ofbanks (less senior debt and more covered bonds).



Also, the “long term” for banks is different from the “long term” for insurers. A
decrease in the demand of insurers for long-term instruments (if this takes place at all)is likely to occur in very long-term maturities63 that banks do not have incentives toissue (20 plus years versus the 5–10 year range needed for banks to satisfy the LCR
and NSFR requirements).



In any case, any decrease in the demand from insurers for banks’ funding instruments
is only likely if the demand for insurance products supported by such assets
decreases.64 Again, the insurance business is liability driven and the demand for assets
depends on the liability structure of the balance sheet. In the end, whether Solvency IIreally represents a funding risk for banks is an empirical issue: it will depend on theelasticities of demand and supply across various insurance business lines, as anincreased cost of capital will be passed through to margins where the demand is leastsensitive to prices.65

Finally, senior unsecured and covered bonds are not placed mainly with insurers. The
largest purchaser of senior unsecured bank bonds is the real money funds sector while
the largest purchaser of bank-covered bonds is the same banking sector. Insurers
represent only 10 percent of total demand for the two instruments (Figure 3).66

63

And this really depends on the extent to which insurers would choose to expose themselves torefinancing/reinvestment risk which is, in turn, not constant but varying over the cycle.
64

The demand for long-term investment and insurance products is often subsidized or mandatory and, therefore,highly inelastic to prices.
65

A similar argument has been made to diffuse the concern that banks’ credit will collapse with theimplementation of Basel III.
66

This of course varies by jurisdiction. In Germany, insurers hold approximately 35 percent of domestic issuesof bank debt.

48
117. More of a concern could be the increased interconnectedness between banks andinsurers. Solvency II and Basel III could indeed result in increased demand for sovereign
debt by both sectors. In other words, exposure to sovereign risk could increase and the typeof interconnectedness between the two sectors could change and could be strengthened
through the balance sheet of the sovereign. In principle, this concern could be diffused by theuse of insurance internal models (which would capture the heterogeneity in credit risk across
EU sovereigns), but their standards are yet to be defined.67 Clearly, strong collaboration
between the regulators of the two sectors would be required to minimize risks of arbitrage
between the use of internal models so that for both banks and insurers appropriate risk
weighted capital is held and that the risk is properly recognized and accounted for.

C. Risk/Product Transfers118. Risk/product transfer across the two sectors could take place in business lines inwhich banks and insurers compete directly. For instance, in some jurisdictions, thetreatment of certain life insurers’ savings products, like term certain annuities, attracts higher

67

The general standards for internal models are already defined in the Solvency II Directive and are to be
developed by Level 2 and Level 3 rules (mainly explaining how these requirements apply). These standards do
not specify in detail how to treat specific risk exposures with an internal model.

49
capital requirements than (say) term deposit.68 The new liquidity requirements proposed
under Basel III should decrease the extent of regulatory arbitrage in the commercialization ofthese similar products. In other jurisdictions, equity investment attracts higher capitalrequirements for banks than for nonlife insurers, and the strengthening of capital treatment ofmarket risk under Basel III could further increase incentives for conglomerates to carryequity investments in a nonlife insurer subsidiary versus a bank subsidiary. Potential for risk
transfer exists in products providing credit default protection, such as CDSs, which can beissued by both banks and insurers, between mortgage lenders and mortgage insurance, and in
trade finance.69 However, establishing clear patterns is difficult, as these will depend on thetreatment of specific risk exposures in the internal models under Solvency II. Close
collaboration between the regulators of banks and insurers will be required in the definitionof such standards so as to minimize the opportunity of model arbitrage and, consequently, thelikelihood that risk migrates inappropriately70 between the two sectors.
119. Risk could also be passed onto customers through risk sharing products in a
non-socially optimal manner. Increased cost of funding and capital could result in different
product mixes offered by banks and insurers. For example, unit-linked life insurers offer
products where most or all of the market risk is borne by the policyholder, many pension
annuity products now provide for periodical re-pricing as a function of mortality experience
as a way to share longevity risk between the provider and the annuitant, and other risk passthrough mechanisms are in principle feasible in other insurance and banking fields. There isalready a strong debate whether consumers are exposed to excessive risk in pension products.
Basel III and Solvency II may exacerbate the problem in Europe as many pension products
are offered by insurers and because of the possibility (being discussed) to extend theSolvency II framework to pension funds.71
120. Risk could finally migrate away from both sectors through the use of
securitization, reinsurance and shadow banking. The joint implementation of Basel III
and Solvency II could lead to increased use of securitization by banks and insurers alike.72
68

In Basel, the capital requirements are on the asset side; there are no capital requirements on the liability side.

69

Basel III considers import/export financings like all other credits or simply like a classic loan without any
security. However, in trade finance, goods constitute a guarantee or collateral for the bank.
70

Some migration might be appropriate, for example, if existing requirements unduly penalize certain risks andcause institutions in one of the sectors to avoid them. An effective modeling of such risks might enable theinstitutions in that sector to compete more successfully in areas where such risks arise. Indeed, if information
reported in Figure 2 did actually reflect differences in capitalization level per unit of risk, adjustments that leadto convergence (and not divergence) should be welcome.

71

Commentators also refer to the possibility of disintermediation. Whether this is a concern depends on theelasticity of the demand and supply of the different products.
72

I.e., increased use of collateralized funding and derivative usage.

50
When the NSFR requirements become binding, securitization has the benefit of removing
long-term assets (like mortgages) from the bank’s balance sheet and thus relieving banksfrom any related Basel III requirement.73 For insurers, an option for offsetting the cost ofcapital under Solvency II, is to use reinsurance and ILS. As witnessed under Basel II, thetendency to move exposure off balance sheets because it reduced regulatory requirements
ultimately led to utilization of the origination and transfer business model, widespread use of
conduits and overconcentration of exposures in less regulated areas of the financial system.
An increased use of these risk-transfer mechanisms could result in more interconnectedfinancial systems with opaque distribution of risks, possibly migrating toward less-regulated
and supervised areas of the financial system. Hence, it is safe to say that the two newaccords: (i) increase the need for regulators/supervisors to improve transparency andstrengthen the oversight of these contagion channels; and (ii) call for a careful definition ofequivalent jurisdictions under Solvency II.
D. Other Potential Sources of Distortion
121. For instance, tax considerations are likely to be a more important source ofarbitrage than current regulatory reforms. Heterogeneous tax treatment of capital items
and similar products/instruments might well dwarf the aforementioned Pillar 1
considerations. In other words, tax-minimization strategies are likely to dominate cost ofcapital minimization strategies for both banks and insurers. For instance, current regulatory
reforms do nothing to reduce the tax incentive to fund financial institutions through debt andtherefore, to discourage leverage. Interest deductibility is perhaps the most important taxrelated distortion, which promotes the design of opaque financial products that add little
economic value but creates leverage and complexity, increasing vulnerabilities in thefinancial system and making them more difficult to monitor.
122. Heterogeneity in supervisory approaches could also be a source, albeit lessimportant, of arbitrage. The insurance market has traditionally (with due exceptions) beenless intrusively supervised than the banking sector. Similarly, due to the only partial
transferability of insurance products, market discipline is likely to be less effective in this
sector than in the banking sector. In other words, Pillar 2 (supervisory approach) and Pillar 3(market discipline) requirements should be considered when assessing potential unintended
consequences of the joint implementation of the new banking and insurance capital accords.
However, we do not think that heterogeneity in supervisory approaches and market discipline
would represent a more important source of arbitrage than the regulatory capital requirements
discussed in this paper, at least in Europe.

73

Given the importance of mortgage credit for many retail banks in continental Europe we expect that the
NSFR will be revised due to calibration needs during the observation period.

51123. Finally, the two accords have not been finalized. There are still too many moving
parts, so potential sources of arbitrage can only be more clearly identified once the details of
the two accords have been finalized.
VII. CONCLUSIONS
124. The nature of capital needed by banks and insurers is naturally different. Banksand insurers have different business models. Banks are asset driven, leveraged, with a large
range of activities only partially overlapping with those of insurers. They have liabilities
providing little (if any) loss absorption and, therefore, are exposed to different risks,
especially liquidity risk. Insurers are liability driven, much less leveraged than banks, funded
mainly through policyholder premiums, with liabilities providing more loss absorption and,
therefore, less exposed to liquidity risk than banks. Also, banks’ asset and liability valuation
and accounting are in part retrospective while both will be more prospective for insurers
under Solvency II, suggesting greater stability in the reported values for banks than for
insurers. Finally, entities in the two sectors have different ways to change the risk profile oftheir balance sheets, with reinsurance not being directly available to banks. Given thesefundamental differences, we expect that the composition, level, and quality of capital will bedifferent across the two sectors.
125. Basel III and Solvency II both attempt to increase the quality of capital in theirrespective sectors, but often have different provisions for similar issues. Their objectives
only partially overlap: Basel III attempts to strengthen the quantity and quality of capital in
an incremental fashion after the recent crisis while Solvency II attempts to strengthen
policyholders’ protection by tailoring the quantity and quality of regulatory capital required
more closely to the risks of each insurer, without necessarily increasing the quantity within
the sector as a whole.74 Indeed, Solvency II represents a complete overhaul of the Solvency I
framework by adopting a market consistent approach to create a realistic balance sheet fromwhich capital requirements are derived. In addition, both accords have had a largely
independent development process subject to inevitable piecemeal negotiations with different
stakeholders. Indeed, while some of the Pillar 1 differences discussed in this paper can be
attributed to the different natures of the capital in the two sectors, many cannot be explained.
126. Provisions that cannot be related to the intrinsic differences between the two
sectors can result in unintended consequences. For instance, it is unclear whether and, if
so, to what extent the cost of capital for banks is going to increase compared to the cost of74

Presumably, enthusiasm by governments for increased capital requirements to apply to banks under Basel III
reflects the desire on their part not to have to incur bail-out costs in the future akin to those they incurred in the
recent credit crisis. Maybe, the apparently reduced emphasis on increased capital requirements under
Solvency II reflects a belief by governments that they are less likely to incur material costs in bailing out
insurers.

52
capital for insurers. On the one hand (i) the lack of an explicit objective to increase capitallevels under Solvency II; (ii) the more restricted geographical application of Solvency II;(iii) the less persuasive need for capital systemic risk surcharges for insurers; and (iv) the yet
to be defined standards for internal models for insurers suggest that cost of capital may
increase more for banks than for insurers. On the other hand, arguments in support of higher
cost of capital for insurers can also be made. But in general, Pillar 1 requirements across thetwo sectors are too different to argue conclusively in either direction. In addition, the newliquidity standards for banks and the new credit risk charges for insurers could affect thefunding patterns of banks and increase the interconnectedness of the two sectors through thesovereign balance sheet. Finally, the two accords may result in an increased use of
securitization for funding purposes by both banks and insurers. Hence, these unintended
consequences could translate into risk migration between or away from the two sectors.
127.

Several policy considerations stem from the aforementioned analysis:Basel III and Solvency II suggest a need for insurance regulators to communicate
with their banking counterparts to understand the combined implications of the
behavioral incentives that the two regimes may provide. This could significantly
reduce the risk of unintended consequences associated with seemingly inconsistenttreatment of same risks under the respective accords. This would also avoid
unintentional arbitrage between internal models and the standardized approach under
Solvency II, as has happened under Basel II.



In addition, while group supervision has been strengthened, concerns about leakages
still remain. This is especially a concern under Solvency II, due to its restricted
geographical application and the potential use of non-equivalent jurisdictions forreinsurance. A key challenge for all groups remains what will be the approach by the
EC to equivalence.

Also, the adequacy of safety nets may need to be reviewed in the future. The likely
increased use of covered bonds by banks for funding purposes would ring-fence
assets so that they are unavailable to depositors and unsecured creditors in case ofresolution.

Basel III and Solvency II could further increase the need to expand the perimeter ofregulation. As both Basel III and Solvency II push banks and insurers toward shorter
duration and less risky business, non-regulated entities and market-based risk transfer
mechanisms might evolve to fill any gap in market capacity that emerges. In addition,
the likely increased use of securitization by banks and insures alike requires astrengthening in transparency and oversight of these contagion channels including
securities lending-related cash collateral reinvestment programs, implementing
macro-prudential measures (such as counter-cyclical margin requirements) related to53
securitization, repos and securities lending where appropriate, and improving market
infrastructure for secured funding markets.
Basel III and Solvency II may lead to excessive risk transfer to consumers andtherefore, may require strengthening consumer protection. To the extent that the newaccords increase capital and funding costs, the product mix offered by banks andinsurers may change and entail additional risks for consumers. For example,
excessive risk transfers could be a concern in the area of pension benefits where
consumers already bear significant investment and longevity risk. Additional risk
transfers to consumers may not be socially desirable from the pension policy point of
view.



Finally, there appears to be a need for empirical investigation about the magnitude of
the impact of unintended consequences. There is no universally agreed set of
unintended consequences and this paper is the first attempt (that we know of) togenerate a set and relate it to the specifics of the Basel III and Solvency II accords. In
addition, there is a general absence of empirical studies on the extent of the impact ofpossible unintended consequences.

APPENDIX I. AN OVERVIEW OF THE BASEL III AND SOLVENCY II ACCORDS
1.
The Basel III and Solvency II accords are coming into effect within the next few
years. Basel III, evolving from Basel II, requires more equity capital and additional long-term
funding. On the other hand, Solvency II establishes a new risk-based capital framework,
replacing Solvency I, where required capital was only a simple proportion of liabilities or
premiums. The following sections give briefings on some significant features of the two
accords and the major shifts that they will introduce.
Basel III2.
A number of enhancements have been proposed to strengthen the Basel accord. New
capital, leverage, and liquidity requirements have been proposed by the BCBS to strengthen
the regulation, supervision, and risk management of the banking sector. Basel III, themodified accord, strengthens the three pillars of Basel II, particularly Pillar 1 with enhanced
minimum capital and liquidity requirements (Figure 4).
Figure 4. Overall Modifications of the Basel II Accord

3.
The modified capital standards and the new capital buffers will require banks to holdmore capital and higher quality of capital. Moreover, the new leverage and liquidity ratios
propose a non risk-based measure to supplement the risk-based minimum capitalrequirements to ensure that adequate funding is maintained during stress periods.
Additionally, the capital required in respect of counterparty credit risk and market risk in the
trading book portfolio has been strengthened, including new capital requirements for Credit
Value Adjustment (CVA), Wrong Way Risk (WWR), Stress Value at Risk, and Incremental
Risk (IR)75 (Figure 5).

75

For extreme value events banks will now have to calculate a stressed VaR based on a 10 day, one side
99 percent confidence interval. The stressed VaR needs to be calibrated to a period of significant and relevant(continued…)

57
4.
The main focus of the Basel accord modifications is to improve the loss-absorption
capacity of banking institutions through stronger capital. Funding and liquidity requirements
are intended to further enhance the short- and long-term stability of the financial system.
Figure 5. Basel III Framework

Basel III new capital regulations
5.
To enhance the capital quality of banks, the modified rules require that common
equity form a larger core component of bank’s capital. The minimum ratio of common equity
to risk-weighted assets will go up to 4.5 percent in 2015 from the currently requirement of
2 percent (Figure 6). The qualifying elements within Tier 1 capital are the common shares,
minority interests, and retained earnings and, from January 2013, other instruments notmeeting the criteria for inclusion in common equity will be excluded and will be phased out
over a 10-year horizon.
financial stress that entails many degrees of freedom in calibration for the bank. The maximum of the stressed
VaR and its average of the preceding 60 days (multiplied by 3) is to be added to the general capital charge.
Additionally, the current specific risk charge (which will be subject to updates) continues to be required.

58
6.
Two types of capital buffers will be required under Basel III: the Capital
Conservation Buffer and the Countercyclical Capital Buffer. Both will be added on top ofcommon equity requirements. Capital Conservation Buffer will be phased in, starting at
0.6 percent of RWAs in 2016 and reaching 2.5 percent of RWAs in 2019. It will need to be
met entirely with common equity. The purpose of this additional capital is to avoid breaching
the minimum capital requirements, particularly in periods of stress. Local supervisors will
decide whether and, if so, for how long local institutions can operate within the buffer range.
Similarly, the countercyclical capital buffer will be added on top of the common equity
requirements. However, it can be met with both common equity and other fully-absorbing
capital (Figure 6). It could be as low as zero, but it could reach up to 2.5 percent of RWAs inperiods of excessive growth. Together with the capital conservation buffer, the required
amount of fully-absorbing capital could reach up to 9.5 percent of RWAs.
Figure 6. Basel III Capital Requirements (percentage of RWA)

Source: BCBS (2010) and Bhimalingam & Burns (2011).

7.
Additional Tier 1 capital of 1.5 percent of RWAs and Tier 2 capital of 2 percent of
RWAs are required under Basel III, which increase the total capital requirements to10.5 percent by 2019. Both of these requirements can be met using either common equity or
financial instruments with loss-absorption features and without any incentive to redeem.
However, under Basel III minimum requirements, capital instruments that do not meet therequirements for inclusion in Tier 1 common equity capital will be excluded as fromJanuary 1, 2013, unless certain conditions are met, in which case they are proposed to bephased out over the following 10 years. Only instruments issued before 12 September 2010

59
would qualify for the proposed transition arrangements. Other existing public sector capital
injections would be grandfathered until January 1, 2018.76
Leverage ratio
8.
Under Basel III, a leverage ratio will be reported to supervisors starting in 2013, withdisclosure after 2015 and with an objective of making it part of Pillar 1 capital requirements
in 2018. It is calculated as the ratio of Tier 1 capital to the total unweighted assets, including
some off-balance sheet assets. Banks would be required to maintain a leverage ratio of
3 percent or more. The unweighted assets include provisions, loans, off-balance sheet itemswith full conversion, and all derivatives. The main purpose of this ratio is to constrain
leverage in the banking sector, while also helping to safeguard against model risk andmeasurement errors.
Liquidity requirements
9.
In order to reduce liquidity risk, Basel III rules introduce two new measures, which
are the Liquidity Coverage Ratio (LCR) and the Net Stable Funding Ratio (NSFR). They aredefined and calculated as follows:

LCR is designed to measure whether a bank has sufficient high-quality liquid
resources to survive an acute stress scenario lasting for one month (30 days); i.e.,
LCR = High quality liquidity assets / Net cash outflow over 30 days;
This ratio has to be greater than 100 percent, subject to a further requirement on thequality of liquid assets. Level 1 assets are included without limits and are held atmarket value, with no haircuts unless required by the home supervisor. Lower-quality
Level 2 assets can only be up to 40 percent of the required asset pool; they have aminimum haircut of 15 percent of market value and they should be diversified.



NSFR has a time horizon of one year and helps to determine whether the maturity
structure of assets and liabilities is sustainable. This ratio can be calculated asfollows:
NSFR = Available Stable Funding / Required Stable Funding;This ratio also has to be greater than 100 percent.

76

The hybrid instruments or the “Innovative” is a mix of instruments having debt as well as equity-like features.
In general, they must be unsecured, subordinated, nonredeemable, and fully paid up. “Grandfathering” meansthat old rules can apply temporarily for a set period of time to smooth the transition phase.

60
10.
Basel III also provides four additional ratios for monitoring liquidity, which are: LCR
by Significant Currency, Contractual Maturity Mismatch, Concentration of Funding, andAvailable Unencumbered Assets.
Solvency II
11.
The Solvency II accord calculates required capital using a total balance sheet
approach, taking into account the actual risk on the balance sheet and any offsetting effects(Figure 7).77 It is scheduled to be implemented in January 2013 and applies to all except thevery smallest insurers and reinsurers in Europe as well as the non-European ones operating inthat region. Like Basel III, Solvency II includes three pillars. Pillar 1 specifies quantitativerequirements related to technical provisions and capital, including both going-concern
Solvency Capital Requirements (SCR) and gone-concern Minimum Capital Requirements(MCR). Pillar 2 contains provisions regarding governance and risk management. Pillar 3
contains guidelines on supervisory reporting and transparency requirements.
Figure 7. Overall Modifications of the Solvency I Accord

77

Solvency I, however, is based on simple ratios of the liabilities or premiums without taking into account thetypes of risks or business.

61
Box 2. Solvency II SCR & MCR Estimation
The SCR:

The overall SCR ratio can be calculated based on the following standard formula:
SCR = BSCR+SCRop-Adj
Where BSCR is the basic SCR, SCRop is the capital charge for operational risk, and Adj is
the adjustment for the risk absorbing effect of future profit sharing and deferred taxes. The
VaR measure reflected in the calculation of this ratio is targeted to a confidence level of
99.5 percent over a one-year time horizon. Moreover, the BSCR is computed before any
adjustments and combines capital charges for market risk, counterparty risk, life and nonlife
underwriting risks, and health underwriting risk.78
The MCR:
The MCR ratio is calculated as follows:
MCR = Max{MCRcombined, AMCR}
Where AMCR is the absolute floor of the MCR, and the MCRcombined is estimated as:
MCRcombined = {Min[Max(MCRlinear; 0.25xSCR); 0.45xSCR]; i.e., the MCRcombined can becalculated by applying the cap and the floor (45 percent and 25 percent of the SCR,
respectively) to the linear MCR. The MCRlinear is the sum of the linear MCRs for each type ofbusiness undertaken by participant, before applying any cap or floor.
78

There is also a module in respect of intangible assets risk.

62
12.
Two control levels of capital are established, which are represented by the SCR andMCR ratios. The SCR aims to cover against 1 in 200 years event while the MCR is theabsolute minimum required capital, which is estimated as a smaller proportion of the SCR.
Breaching of the MCR level of capital requirements leads to immediate supervisory action,
which can trigger the withdrawal of supervisory authorization. The key component of the
SCR is the Basic SCR, which is computed before any adjustments and combines capitalcharges for five types of major risks. On the other hand, the calculation of the MCR is basedon a linear approach, with the result being restricted to a range of between 25 percent and45 percent of the SCR, but not less than an absolute monetary floor. For supervisory
purposes, the difference between the SCR and the MCR can be considered as an intervention
window to reduce the risk that the MCR will be breached. Box 2 illustrates how both SCR
and MCR ratios are estimated.

63
APPENDIX II. CAPITAL REQUIRED FOR VARIOUS RISKS UNDER BASEL III ANDSOLVENCY II
1.
The risk areas considered under Pillar 1 of the two accords differ from one another.
Basel III deals with credit risk, market risk, and operational risk. Solvency II deals withnonlife underwriting risk, life underwriting risk, health underwriting risk, market risk,
counterparty default risk, and operational risk.79
2.
Under Pillar 1 of the Basel III accord, three major classes of risks are considered:credit risk, market risk, and operational risk. Credit risk originates mainly in the banking
book, with the exception of credit counterparty risk through Securities Financing
Transactions (SFT) and OTC derivatives, which originates in the trading book and was aspecific object of the Basel III revisions. Market risk (interest, equity, FX, and commoditiesrisk) originates mainly in the trading book.80 Operational risk is the risk of losses resulting
from inadequate or failed internal processes, people and systems.
3.
Pillar 1 of Solvency II considers these same classes of risk, as well as underwriting
risk, which is unique to the insurance sector. Underwriting risk is the risk of loss associatedwith both the perils covered by insurance policies and the processes followed in the conductof the insurance business, such as risk selection and claims settlement.
4.
This appendix focuses on the treatment of credit and market risks for capitalrequirement purposes under the standardized approaches of the Basel III and Solvency II
accords. However, it does not discuss operational or underwriting risks, or the internal
models approaches to credit and market risks.
Credit Risk
5.
Basel III did not materially change the Basel II provisions for treatment of credit riskin the banking book. The only discussion taking place relates to the intention of decreasing
the dependency of capital charges on external ratings under the various approaches and to
reduce the procyclicality of capital charges stemming from the mechanics of internal models
used under the internal ratings-based approach.81 Regarding both issues, no concrete
amendments to the solvency accord had been formulated at the time of writing.

79

See also Appendix I for a graphical representation of these risk components under both accords.

80

A bank’s trading book holds typically instruments such as credit derivatives, securitizations, and leveragedloans, which are marked-to-market and held for shorter terms. The banking book holds traditional loans andassets, which are valued at cost and held for longer terms.
81

See CEBS (2009) Position paper on a countercyclical capital buffer.

64
6.
Minimum credit risk weights under the standardized approach are reported inTable A1. Claims on sovereigns and their central banks are risk weighted between
zero percent and 100 percent, depending on their ratings. Claims on noncentral government
public sector entities (PSE) receive the same risk weights as banks, without preferential
treatment of short term claims, but supervisors have the discretion to assign same rating as
sovereigns when these entities have revenue raising powers. Claims on multilateraldevelopment banks (MDB) are risk weighted following option 2 for banks without
preferential treatment of short-term claims.82
7.
Two options are available for determining the requirement in respect of claims onbanks and securities firms in a given jurisdiction. Under option 1, banks have no externalratings and claims receive a one-less-favorable rating category than the sovereign ofincorporation.83 Under option 2, banks receive their own ratings and unrated banks receive
50 percent risk weight. In addition, under this option, the supervisor can treat short-term
claims84 preferentially by granting a one-more-favorable rating category. Finally, claims on
securities firms receive the same ratings as claims on banks if they fall under comparable
regulatory and supervisory arrangements (risk-based capital), otherwise they are treated asclaims on corporates.
8.
Claims on corporates, including insurers, receive a similar treatment to claims onbanks, with the exception of higher risk weights for corporate rated B+ to B-. In addition,
supervisory authorities may authorize banks to risk weight all corporate claims at 100 percent
without regard to external ratings.
9.
Retail loans and residential mortgages are by definition unrated and receive risk
weights of 70 percent and 35 percent, respectively. Claims secured by commercial real estateshould receive a 100 percent risk weight, but for well-developed and long-establishedmarkets, lower risk weights are possible. Finally, the unsecured portion of nonperforming
loans (NPLs) with less than 20 percent provisions receives a 150 percent risk weight, reduced
to 100 percent when provisions are more than 20 percent, and with discretion to reduce therisk weight to 50 percent when provisions are more than 50 percent of the outstanding
amount of the loan.

82

Claims on BIS, IMF, BCE and EC can receive a zero weight. So can highly rated MDBs such as: the CDB,CEDB, IBRD, IFC, ADB, AfDB, EBRD, EIB, EIF, IADB, IDB, and NIB.

83
84

Capped at 100 percent for unrated sovereigns.

Claims: (i) with contractual maturity of less than three months, and (ii) which the supervisor is satisfied are
not going to be rolled over.

65
10.
Higher risk claims receive a default weight of 150 percent, while other assets receivea default risk weight of 100 percent. Again, under Pillar II, the supervisory authority may
increase such weights.
11.
Off balance sheet items are risk weighted through the use of credit conversion factors(CCF). These vary according to the transaction. For instance, repos, reverse repos, longpositions in forward markets, and securities lending all receive a CCF of 100 percent.
Commitments with an original maturity of more than one year or contingent claims
associated with performance bonds, warranties and letters of credit receive a CCF of
50 percent. Finally, commitments with an original maturity of less than one year receive a
CCF of 20 percent, or 0 percent the commitment can be canceled unilaterally by the bank.

12.
Under Solvency II, credit risk is dealt with in two risk modules. The spread risk submodule of market risk covers, among other things, the credit risk associated with investments
in bonds. The counterparty default risk module covers, among other things, the credit risk
associated with derivatives.
13.
The capital required under the spread risk sub-module depends on both the rating
category of an asset and its duration. The market value of an asset is multiplied by a ratingdependent stress factor, as well as by its duration, which is subject to floors and caps.
Accordingly, long duration assets are subject to much higher capital requirements than shortduration assets of the same rating category. The stress factors and duration limitations forsome key types of assets held by insurers are shown in Table A2.

Notes: 1/ Exposures to non-EEA governments and central banks denominated and funded in thedomestic currency.

14.
Some assets receive special treatment under the spread risk sub-module. There is no
capital requirement for borrowings by or demonstrably guaranteed by the national
government of an EEA state, issued in the currency of the government, or issued by aspecified multilateral development bank or international organization. Mortgage coveredbonds and public sector covered bonds are also treated differently. If they meet certain
requirements and are rated AAA, they are subject to a stress factor of 0.6 percent and a
duration cap of 53 years.
Market Risk
15.
Market risk is defined as the risk of losses in on- and off-balance sheet positions
arising from changes in market prices. Under Basel III, market risk includes interest rate andequity risk related to instruments in the trading book and foreign exchange and commodity
risk throughout the bank. The treatments of various types of market risk under the two
accords are contrasted below.
16.
Basel III modifies the standardized measurement method for market risk by adding
the concept of correlation trading. The correlation trading portfolio incorporates
securitization exposure and nth-to-default credit derivatives with certain criteria. A minimum
capital charge of 8 percent was introduced for exposures in correlation trading portfolios,
while a transition period until end of 2013 was given for capital charges for noncorrelation
trading portfolios.
17.
Basel III provides alternative approaches to measure the price risk of options,depending on the significance of a bank’s trading portfolio. If a bank is engaged in limited
options-buying activities, then it is allowed to adopt a simplified approach. On the other67
hand, if it both writes and purchases options, then it is expected to use intermediateapproaches85 or internal models.
Interest Rate Risk
18.
Basel III does not impose a capital charge for interest rate risk in the banking book. It
instead deals with the risks associated with maturity mismatches through the liquidity
requirements (LCR) and the net stable funding ratio (NSFR).

19.
However, capital is required for interest rate risk in the trading book. Capital risk
charges apply to both specific and general market risk. Under the specific risk category, there
are four types of rules for determining the capital charge on certain debt or similar
instruments, dealing respectively with issuer risk, unrated debt, non-qualifying issuers, andpositions hedged by credit derivatives. The capital charges for government and other85

The intermediate approaches include the “Delta-Plus” method and the “scenario” approach.

68
categories are shown in Table A3.86 The qualifying category includes those securities issued
by the public sector as well as those rated as investment grade, which are subject tosupervisory approval. Also, the qualifying category might include unrated securities if they
can be rated equivalent to investment grade and listed in the stock exchange. On the other
hand, instruments issued by non-qualifying issuers are weighted as non-investment grade andthe supervisory authorities can apply higher charges.
20.
Basel III did not change the capital charges for general market risk, which is the riskof loss arising from changes in market interest rates. The risk can be measured using either
the maturity or duration methods. The capital charge is calculated as the sum of: the net shortor long position in the trading book, the small and large proportion of matched positions, andthe net charge for positions in options. Interest rate derivatives, off-balance sheet
instruments, and swaps in the trading book that react to changes in the interest rate must be
accounted for whenever possible.
21.
Under Solvency II, capital is required for interest rate risk for all assets and liabilities
for which the net asset value is sensitive to changes in the term structure of interest rates orinterest rate volatility. Assets sensitive to interest rate movements will include fixed-income
investments, policy loans, and interest rate derivatives. Insurance liabilities, which are basedon the discounted value of future cash-flows, are sensitive to changes in the rates at whichthose cash-flows are discounted. The more significant the mismatch between the term
structures of assets and liabilities, the higher the capital that will be required for interest rate
risk.
22.
The capital requirement for interest rate risk is determined using two pre-defined
scenarios, involving instantaneous upward or downward shifts in the term structure. The
relative changes under the two scenarios are shown in Table A4, for selected maturities.
Irrespective of the stress factors, the absolute change of interest rates in the downward
scenario should at least be one percentage point, except that the shocked rate cannot be
negative. The changes in the net value of assets and liabilities due to re-valuing all interest
rate sensitive items using the altered term structures are calculated, with the capitalrequirement being the greater of the two absolute results.

86

The instruments under the government category include bonds, treasury bills, and other short-term
instruments.

Equity Risk
23.
As with interest rate risk, equity risk has also two charges under Basel III, for specificand general market risk.87 Basel III modifications no longer allow national authorities to grantlower capital specific risk charges for liquid and well-diversified equity portfolios. For both
specific and general market risk the capital charge is now 8 percent.
24.
The remainder of the accord on equity risk remains unchanged from Basel II. Banks
are still required to include equity derivatives in the measurement system and convert
exposures into exposures in the relevant underlying. Matched long and short positions in an
identical equity in each market can be fully offset. In relation to equity index exposures, afurther capital charge of 2 percent will apply to the net long or short position to cover factors
such as execution risk.
25.
The capital required for equity risk under Solvency II is determined by applying
immediate shocks to the values of equities. The shocks are reductions of 39 percent on global
equities88 and 49 percent on other equities and commodities, except that no shock is applied
to participations in financial and credit institutions and a shock of 22 percent is applied toother strategic participations. Correlation of 0.75 between the global and other categories isassumed. Solvency II also intends to incorporate a counter-cyclical symmetric adjustment
into the equity shock applied. For example, a 30 percent global equity shock was applied in
QIS5 instead of the base 39 percent shock.

87

Specific risk is defined as the bank’s gross equity positions (i.e., the sum of all long equity positions and of all
short equity positions) and general market risk as the difference between the sum of the longs and the sum of

Commodities Risk
26.
Basel III remains unchanged in respect of commodities risk.89 To measurecommodities risk and applicable capital charges, banks can adopt (under the standardized
approach) either a maturity ladder method or a simplified method. The capital charge fordirectional risk is equal to 15 percent of the net position, long or short, in each commodity
and an additional 3 percent capital charge of the bank’s gross positions, for protection against
other types of risks.
27.
Under Solvency II, commodities risk is treated as equity risk. The capital requirement
is based on a 49 percent shock in the value of the commodity position.
Foreign Exchange Risk
28.
Capital required for foreign exchange risk remains unchanged under Basel III. Banks
are required to calculate their net open positions in different currencies and gold. Then auniform 8 percent capital charge is applied to the higher of the net long currency position or
the net short positions (across currencies and gold). A bank doing negligible business in FX
or not taking FX positions with its own funds can be exempted from the capital charges.
29.
Under Solvency II, required capital is determined in respect of each of an insurer’s
individual currency positions. The insurer’s investment policy is to be taken into account,which could include hedging arrangements and gearing. For each currency, the contribution
to the capital requirement is determined as the maximum of the results of a 25 percent rise ora 25 percent fall in the value of the currency in relation to the local currency. The mostsignificant impact of this requirement is likely to be at the group level, for insurers withequity investments in foreign subsidiaries.
