Mark Carney: 7th Bundesbank Lecture 2010 - the economic
consequences of the reforms
Remarks by Mr Mark Carney, Governor of the Bank of Canada, at the 7th Bundesbank
Lecture 2010, Berlin, 14 September 2010.

"The power to become habituated to his surroundings is a marked characteristic
of mankind... We assume some of the most peculiar and temporary of our late
advantages as natural, permanent, and to be depended on, and we lay our plans
accordingly. On this sandy and false foundation we scheme for social
improvement and dress our political platforms."
- J. M. Keynes, The Economic Consequences of the Peace
Introduction
Keynes wrote prophetically of the economic consequences of the Treaty of Versailles. Could
the same be said of current financial reforms? Are policy-makers taking for granted the
essential role performed by finance in a vain pursuit of its risk-proofing? Do we assume that
our "late advantage" of an open, global capital market and trade environment is a "natural,
permanent" feature of the economic landscape?
Or is the other extreme possible? Are we being too timid? Consider the jaded attitudes of the
bank CEO who recounted: "My daughter called me from school one day, and said, 'Dad,
what's a financial crisis?' And, without trying to be funny, I said, 'This type of thing happens
every five to seven years.'"1
Should we be content with a dreary cycle of upheaval?
Such resignation would be costly. Even after heroic efforts to limit its impact on the real
economy, the global financial crisis left a legacy of foregone output, lost jobs, and enormous
fiscal deficits. As is typically the case, much of the cost has been borne by countries,
businesses, and individuals who did not directly contribute to the fiasco.
If what's past is prologue, growth will be lower and unemployment higher for years to come.
The Bank of Canada forecasts that, as a result of the crisis, cumulative foregone economic
output from 2009 to 2012 will be 16 per cent of GDP in Europe and 9 per cent of GDP in
Canada (see Appendix, Chart 1). Over the longer term, we estimate that these shortfalls
could grow to about 40 per cent and 30 per cent of respective GDP. Given the synchronous
nature of this global crisis, there are reasons to fear such severe outcomes.
Surely, and contrary to what some in the industry would have you believe, there is some
price worth paying to reduce such tail risks in the future. This past weekend's historic
Basel III agreement strikes exactly the right balance.
In my remarks today, I will focus on the costs and benefits of financial sector reform. I will
argue that the economic case is compelling and the basic stakes enormous. Financial crises
are normally followed by financial repression; economic downturns, by increased
protectionism. Without credible, coordinated financial reforms, we risk losing the open trading
and financial system that has underpinned the economic miracle of recent times.
The role of the financial sector
Before analysing the impact of the reforms, allow me to discuss briefly the role of the
financial sector and how it failed during the crisis.
By translating savings into productive investment, finance is central to economic growth. It
has three core functions. First, through the payments system, it facilitates decentralized
exchange, which is fundamental to the functioning of a market economy.
Second, finance transforms the maturities of assets and liabilities, taking short-term liabilities,
such as deposits, and transforming them into long-term assets, such as mortgages or
corporate loans. Households and businesses can therefore do the reverse, holding
shortterm assets and longer-term liabilities. This helps them to plan for the future and to manage
risks arising from uncertainties over their cash flows. The social value of maturity
transformation is unquestioned, but its performance creates fundamental risks, which
requires public intervention.2
Third, the financial system intermediates credit, channelling funds from savers to investors.
This allows savers to diversify their risk and everyone to smooth consumption over time and
across states of the world. Young families can borrow to buy a house; students can pay for
university. People can invest for their retirements and businesses can finance working capital
and investment. However, if risk is persistently mispriced, these savings and investments will
be misallocated and economic welfare reduced.
The crisis
Financial services are supplied by a combination of banks and markets. In recent years,
markets grew to the point that they became important alternatives to banks for corporate and
household finance. More and more of the traditional functions of banks - including maturity
transformation and credit intermediation - were conducted through a broader range of
intermediaries and investment vehicles, which have been collectively referred to as the
"shadow banking" system.3 All countries participated in these trends, to varying degrees.
From a financial system perspective, the deepening of markets is generally welcome
because it makes the system more robust and increases competition. However, while
markets expand the choices and lower the prices available to financial consumers, they
function differently from banks. Unlike banks, markets rely more completely on confidence for
liquidity. To maintain that confidence, markets need clear rules and robust infrastructure.
In response to the increased competitive pressure from markets, banks employed three
strategies: increasing leverage, greater use of securitization, and the writing of deep
out-of-the-money options. Though not recognised at the time, each increased risk in the
system.
By borrowing in short-term wholesale markets to fund asset growth, banks became more
dependent on continuous access to liquidity in money and capital markets.
By using securitization to diversify the funding sources and reduce credit risks, banks created
new exposures. The severing of the relationship between originator and risk holder lowered
underwriting and monitoring standards. In addition, the transfer of risk itself was frequently
incomplete, with banks retaining large quantities of supposedly risk-free leveraged super
senior tranches of structured products.
These exposures were compounded by the rapid expansion of banks into over-the-counter
derivative products. In essence, banks wrote a series of large out-of-the-money options in
markets such as those for credit default swaps.4 As credit standards deteriorated, the tail
risks embedded in these strategies became fatter. With pricing and risk management lagging
reality, there was a widespread misallocation of capital.
The magnitude of these developments was remarkable. In the final years of the boom, when
complacency about liquidity reached its zenith, the scale of shadow banking activity
exploded. The value of structured investment vehicles, for example, tripled in the three years
to 2007. Credit default swaps grew sixfold.
Financial institutions, including many banks, came to rely on high levels of liquidity in
markets. Short-term money markets were the predominant source of financing for the
one-third increase in the gross leverage of U.S. investment banks, U.K. banks, and
European banks. The system's exposure to market confidence was enormous.
Through all of this, a mirage formed of relentlessly expanding profitability in the financial
sector. In the United States, between 2000 and 2006, corporate profits in the sector
averaged over 36 per cent of total profits. It appeared briefly that finance was the ruler, rather
than a servant of, the real economy. The large losses and costly bailouts required to repair
balance sheets shattered this illusion.5
The shortcomings of regulation were similarly exposed. The shadow banking system was not
supported, regulated, or monitored in the same fashion as the conventional banking system,
despite the fact they were of equal size on the eve of the crisis.6
There were also major flaws in the regulation and supervision of banks themselves. Basel II
fed procyclicalities, underestimated risks, and permitted excess leverage. Gallingly, on the
day before each went under, every bank that failed (or was saved by the state) reported
capital that exceeded the Basel II standard by a wide margin.
Most fundamentally, the global financial crisis revealed the fallacy of composition that strong
individual financial institutions collectively ensure the safety and soundness of the system as
a whole. Even the most vigilant, microprudential regulatory regime can be overwhelmed by
systemic risks. As a consequence, policy-makers now recognise that systemic risk is the
product of the resiliency of financial institutions, the robustness of systemically important
markets, and the interconnectedness between institutions and markets.
The G-20 reform agenda
The G-20 has initiated an extensive program of reform designed to improve the safety and
robustness of the global financial system. The measures are mutually reinforcing, and all are
necessary.
Building robust markets
The first strategy is to build robust financial markets by improving infrastructure and
transparency.
In particular, keeping markets continuously open requires policies and infrastructure that
reinforce the private generation of liquidity in normal times and facilitate central bank support
in times of crisis. The cornerstone is clearing and settlement processes with risk-reducing
elements, particularly central clearing counterparties or "CCPs" for repos and OTC
derivatives. Properly risk-proofed CCPs act as firewalls against the propagation of default
shocks across major market participants. Through centralised clearing, authorities can also
require the use of through-the-cycle margins, which would reduce liquidity spirals and their
contribution to boom-bust cycles.7
Reducing the interconnectedness between institutions and markets
The second G-20 imperative is to create a system that can withstand the failure of any single
financial institution. From Bear Stearns to Hypo Real Estate to Lehman Brothers, markets
failed that test.
Today, after a series of extraordinary, but necessary, measures to keep the system
functioning, we are awash in moral hazard. If left unchecked, this will distort private
behaviour and inflate public costs.
As a consequence, there is a firm conviction among policy-makers that losses incurred in
future crises must be borne by the institutions themselves. This means management,
shareholders, and creditors, rather than taxpayers.
Measures to expose fully firms to the ultimate sanction of the market will also reduce the
interconnectedness between institutions. In addition to changes to market infrastructure,
priorities include: staged-intervention regulatory regimes, "living wills" for banks, and better
cross-border resolution regimes.
Another promising avenue is to embed contingent capital features into debt and preferred
shares issued by financial institutions. Contingent capital is a security that converts to capital
when a financial institution is in serious trouble, thereby replenishing capital without the use
of taxpayer funds. Contingent conversions could be embedded in all future new issues of
senior unsecured debt and subordinated securities to create a broader bail-in approach. Its
presence would also discipline management, since common shareholders would be incented
to act prudently to avoid having their stakes diluted by conversion. Overall, the Bank of
Canada believes that contingent capital can reduce moral hazard and increase the efficiency
of bank capital structures. We correspondingly welcome the Basel Committee's recent public
consultation paper on this topic.
Improving the resiliency of financial institutions
The third priority is to improve the resiliency of financial institutions themselves. Creating
more resilient institutions requires more and better capital, improved balance sheet liquidity,
and enhanced risk management.8 This past weekend's Basel III agreement delivers on these
objectives by:

Creating global standards for liquidity.

Raising substantially the quantity, quality, consistency, and transparency of the
Tier 1 capital base.

Introducing a leverage ratio as a complement to the Basel II risk-based framework.
The leverage ratio is, in effect, a safety harness that is designed to protect against
risks that regulators think are low but which, in fact, are not.

Introducing a capital conservation buffer above the minimum capital requirement to
ensure that banks and supervisors take prompt corrective action and that banks can
absorb losses during periods of financial and economic stress. This conservation
buffer is to be complemented by a countercyclical buffer, which would vary over
time. It should be at its maximum in periods when credit is growing rapidly and
system-wide risks are rising. In times of stress, the buffer would be reduced to
ensure that the flow of credit is not undermined by regulatory constraints.
The goal is to make financial systems less vulnerable to booms and busts so that crises are
less frequent and less severe. Through evidence-based analysis, policy-makers can
determine the package of reforms that will maximise these net economic benefits.
It is to this issue that I will now turn.
The benefits of reform
The potential economic benefits of stronger capital and liquidity standards are significant.
These benefits emerge from a variety of sources:

Higher capital and liquidity standards will contribute to a lower incidence of financial
crises.

The severity of financial crises could also be reduced.

The economy should benefit from smoother economic cycles.

Higher standards should help to reduce the risk that resources are misallocated.
To put the magnitude of potential gains into context, consider more closely the costs of
financial crises.
In the 10 years following a financial crisis, the median output growth rate decreases by 1 per
cent, and the unemployment rate increases by 5 percentage points.9 Experience suggests
that costs build well into the future. In studies released last month, the Basel Committee
found that the median cumulative loss of past financial crises was 63 per cent of national
GDP.
Given the scale of potential losses, there are clearly large benefits to reducing the frequency
of crises (Chart 2). The extensive analysis of the Basel Committee suggests that higher
capital and liquidity standards would do just that. In particular, the combination of
strengthened liquidity standards and a 2-percentage-point increase in bank capital ratios
would raise the annual expected level of GDP by 1.8 per cent relative to trend.
Because this improved performance accrues over time, it is a gift that keeps on giving. Using
a conservative real discount rate of 5 per cent, the cumulative present value of this better
performance is equivalent to more than 35 per cent of GDP, or €0.9 trillion for Germany.10
Some in Canada argue that our sound financial system implies that the potential gains are
small for our country and the G-20 reforms are, therefore, unimportant. This is misguided. In
open economies such as ours and Germany's, reducing the incidence of foreign crises is
even more important than domestic benefits. Today's reality is one of deep interconnectedness,
where financial problems in other regions spill rapidly into our own. In an increasingly
multipolar economy, we simply cannot afford to lurch from crisis to crisis every five years. To
reduce this frequency, we need a strong, universally applied framework. The Basel III rules,
combined with the FSB and IMF's review processes, have the potential to be just that.
Costs of reform
Despite the clear benefits, stronger prudential standards also impose costs.
Banks can follow several strategies to meet regulatory demands for higher capital
requirements. Most obviously, they could raise additional capital in public markets. If given
sufficient time, they could generate capital internally through retained earnings. In addition,
they could pass on some of the costs of the higher standards to their customers through
higher interest spreads or increased fee income. Finally, they could shed, or slow the growth,
of assets.
Past experience suggests that banks will use a combination of all these methods.11 However,
to be conservative, the Basel report assumes that banks would recoup the cost of higher
capital and liquidity requirements entirely through higher lending spreads. The long-term
estimate of the increase in lending spreads is then used as an input to a variety of models to
assess the impact on output. By combining strengthened liquidity standards with a
2-percentage-point increase in bank capital ratios, expected output growth, relative to trend,
is reduced by 0.25 per cent on average for the countries analysed (0.30 per cent for
Canada). In present-value terms, this equates to about 5 per cent of GDP.
Together with these long-run costs, there are also costs incurred during the transition period.
The Basel study estimates these through a sophisticated approach using a wide range of
models.12 The result for the group is a 1.1 per cent cumulative reduction in GDP over a
four-year transition period (in present value).
A conservative estimate of the net benefits
Netting the long-run benefits of less frequent financial crises with the long-run and transition
costs yields average net benefits for G-20 economies of 30 per cent of GDP in present-value
terms, or about €10 trillion (Table 1).13
This estimate is conservative. The analysis understates the benefits of the new rules and
errs on the side of overstating the costs. This bias is reflected in several key assumptions.
First, banks are assumed to fully pass on the costs of higher capital and liquidity
requirements to borrowers rather than reducing their current returns on shareholders' equity
or operating expenses, such as compensation, to adjust to the new rules.
Consider the alternative. If banks were to reduce personnel expenses by only 10 per cent
(equal to a 5 per cent reduction in operating expenses), they could lower spreads by an
amount that would completely offset the impact of a 2-percentage-point increase in capital
requirements.
Second, higher capital and liquidity requirements are assumed to have a permanent effect on
lending spreads, and hence on the level of economic output. No allowance is made for the
possibility that households and firms may find cheaper alternative sources of financing.
Third, the discount rate used to calculate net benefits was more than twice current real
interest rates and the longer-run real growth rates of the Canadian and German economies.
Finally, the benefit quantified is the gains to GDP resulting from a reduced probability of
only
future financial crises.
Other benefits from financial reforms are substantial
However, there are a variety of other potential benefits from higher capital and liquidity
standards and the broader range of G-20 reforms.
First, the variability of economic cycles should be reduced by a host of macroprudential
measures. Analysis by the Bank of Canada and the Basel group suggests a modest
dampening in output volatility can be achieved from the Basel III proposals, as higher capital
and liquidity allow banks to smooth the supply of credit over the cycle. For instance, a
2-percentage-point rise in capital ratios lowers the standard deviation of output by about
3 per cent.
A much more significant impact can be expected from other macroprudential instruments
under consideration. These include varying loan-to-value and other credit terms in mortgage
markets, adopting through-the-cycle margining in core funding markets, and the introduction
of countercyclical capital buffers.
The Bank of Canada has modelled the potential impact of such a time-varying buffer and
translated the gains from reduced volatility into domestic consumption and GDP. The
preliminary findings suggest that the potential gains are in the range of 4 per cent to 6 per
cent of GDP in present-value terms. In other words, countercyclical buffers alone could
increase the net benefits of reforms by about 20 per cent. It is reasonable to expect similar
results for other countries.14
Second, there is a range of initiatives under consideration to reduce moral hazard, including
new frameworks for the effective resolution of banks, more intensive supervision of key
institutions, the introduction of contingent capital, and the creation of more robust
infrastructure.
Adoption of these measures should further reinforce the ability of Basel III standards to
reduce the probability of crises and thereby increase net benefits.
Third, the totality of the G-20 reforms has the potential to shift the balance between resiliency
and competition. By creating a system that is robust to the failure of a single firm, reforms
could increase the competitive intensity in the financial services sector, with attendant
benefits.
A financial sector that is less volatile, less prone to debilitating crises, and more robust in the
face of adverse shocks is likely to be viewed more favourably by investors and attract the
investment needed to continue to expand in a sustainable manner. By reducing moral
hazard, incumbents will also enjoy fewer oligopolistic privileges behind regulatory barriers to
entry.
Greater competition commonly leads to more innovative and diverse strategies, which would
further promote resiliency of the system. Greater competition and safer banks may also
contribute to lower expected return on equity (ROE) for financial institutions. This, in turn,
could help offset the costs and increase the net benefits discussed earlier.
These gains from competition could be considerable. The financial services sector earns a
50 per cent higher return on equity than the economy-wide average. If greater competition
leads to a one-percentage-point decline in the ROE (through a decline in spreads), the
estimated cost from a one-percentage point increase in capital would be completely offset.
Conclusion
The fundamental objective of the reforms is to create a system that efficiently supports
economic growth while providing financial consumers with choice. The system must be
robust to shocks, dampening, rather than amplifying, their effect on the real economy. It
should also support sensible innovation. The system needs stable banks and robust markets,
since both play a central role in financing, and, if properly structured, each can support the
other.
This means ensuring that individual financial institutions are stronger and less systemically
important, that more options for liquidity are available in all states of the world, and that the
new measures promote competition.
A fully risk-proofed system is neither attainable nor desirable. The point is not to pile up so
much capital in our institutions that they are never heard from again, either as a source of
instability or of growth. The challenge is to get the balance between resiliency and efficiency
right. The Basel III agreement accomplishes these objectives. Moreover, a careful analysis
indicates that the economic case for the reforms is compelling.
Most fundamentally, successful implementation of the G-20 agenda will increase the
likelihood of an open, flexible international financial and trading system. Modern Germany
has prospered in this environment and has a great stake in leading the G-20 in building a
more secure foundation for modern prosperity.
The Bundesbank has led the development of many of these reforms. Tremendous progress
was made this past weekend, but there is still more to do. Germany's continued leadership in
the coming weeks and months will be critical, so that we can finish building a solid financial
foundation for growth and social improvement. We should all heed the words of President
Weber: "Policy-makers now have to muster the political will to take the necessary steps,
however contested and painful they might be".15
Thank you.
