Preface

In the early 1980s, several large U.S. banks verged on insolvency because of losses from

their international lending exposure in emerging-market countries. More recently, episodes

of financial instability abroad have raised the question of how vulnerable U.S. banks currently are to serious downturns in foreign economies or to crises in global financial markets.

This Congressional Budget Office (CBO) paper reports on the U.S. banking industry's foreign exposure and discusses the limitations of currently reported measures of such financial

claims. The paper was prepared at the request of the Senate Committee on Banking, Housing, and Urban Affairs. In keeping with CBO's mandate to provide objective, impartial analysis, this report makes no recommendations.

Summary

Acritical part of the business of modern banking institutions is managing the risk of

financial loss—a risk that in recent years has become both more diverse and more complex

as the global scope of many U.S. banks' operations exposes them to the vagaries of foreign

markets. Understanding the amount and types of risk that banks assume in both their domestic and foreign operations is critical for bank regulators seeking to ensure the safety and

soundness of the banking system. It is also critical for private investors, who impose market

discipline through their transactions with and investments in those banks.

This Congressional Budget Office (CBO) paper focuses on the foreign exposure of U.S.

banks—the money owed to them by residents, businesses, and governments of other countries—and the difficulties involved in measuring it and assessing its accompanying risk.

Foreign exposure is worthy of special attention because episodes of financial instability originating in other countries, as well as the fact that foreign parties are often beyond the reach of

the United States' legal system and its debt-recovery mechanisms, might trigger losses that

threaten U.S. banks' stability. Also motivating close scrutiny of banks' foreign claims is the

concentration of international banking operations in a few large institutions. Such concentration heightens concerns about risk to the financial system as a whole.

Foreign exposure in and of itself is not a measure of risk. Exposure is a measure of banks'

business; consequently, it approximates the amount a bank could theoretically lose rather

than gauges the likelihood of losses. Thus, banks must assess the level of risk associated with

their exposure. The risks most pertinent to banks' foreign exposure are credit risk, market

risk, liquidity risk, and country risk. Credit risk refers to the possibility that borrowers will

not be able to pay what they owe. Market risk, also known as price risk, is the risk that the

value of a bank's assets or liabilities will change as interest rates, exchange rates, or other

prices vary. (For example, banks with foreign exposure face significant price risk in the form

of changes in foreign exchange rates.) Liquidity risk involves the possibility that assets cannot be sold quickly without a big effect on their price. Country risk, which encompasses

political, legal, and economic considerations, refers to the difficulties that banks may confront in collecting what is owed to them by residents in a specific country. Systemic risk is

the possibility that the failure of one financial institution could trigger a chain reaction of

defaults throughout the financial system. That risk is naturally a primary concern of regulators and policymakers.
viii U.S. BANKS’ EXPOSURE TO FOREIGN FINANCIAL LOSSES

Measuring and Reporting Foreign Exposure

Regulators require banks to provide data on their foreign exposure, which are published in

the Country Exposure Lending Survey (CELS). The CELS reports data for groups of banks

rather than for specific institutions, for the stated purpose of protecting banks' confidentiality.

Foreign claims are separated into two categories, cross-border claims and local country

claims, in part because conditions in and actions taken by foreign nations are likely to affect

the two categories differently. Cross-border claims originate outside the foreigners' home

countries, usually at a U.S. bank's head office in the United States. Local country claims

originate at the offices of U.S. banks in the foreigners' home countries. A bank's total foreign

exposure is the sum of its cross-border and local country claims.

The large U.S. and foreign banks that account for most of the transactions in world capital

markets profit by making direct loans and by intermediating—acting as the middleman

for—other transactions that transfer risk from one party to another. In foreign transactions,

banks have traditionally provided mechanisms to hedge the foreign exchange risk of their

customers. But increasingly, they are also providing customized financial instruments,

known loosely as over-the-counter (OTC) derivatives, ostensibly to hedge other types of risk

as well. Such investments, which in many cases take the form of contracts between two parties, "derive" their value from changes in the price of some underlying asset or from shifts in

an index or rate. 

OTC derivatives allow their users to "unbundle" a wide variety of risks and thus help markets to function efficiently. But the complexity of many OTC derivative contracts may

obscure the nature of the risks that one party is transferring and the ability of the other party

to assume them. That loss of transparency often makes it difficult for regulators and investors to assess the risk that OTC derivatives may pose.

Changes in U.S. Banks' Foreign Exposure Since 1982

The data collected about banks' foreign exposure permit only limited insight into the risks it

may represent for those banks. Some changes in that exposure since 1982 may have decreased those risks, whereas other developments may have increased them.

A factor suggesting less vulnerability for banks today than in the early 1980s is that although

foreign exposure has grown in real (inflation-adjusted) terms, it has shrunk relative to bank

capital (see Summary Table 1). That ratio dropped during the 1980s largely because banks

were reducing their foreign exposure; it continued to decline in the 1990s primarily because

banks built up their capital. Capital levels rose in large part because of a lengthy period of

NOTE: U.S. banks' foreign exposure is the amount owed to them by (or their financial claims on) residents, businesses, and

governments of other countries. The total foreign exposure of U.S. banks is the sum of their cross-border and local

country claims. Cross-border claims are amounts owed by foreigners that originate outside the foreigners' home countries, usually at a U.S. bank's head office in the United States. Local country claims are amounts owed by foreigners that

originate at the offices of U.S. banks in the foreigners' home countries. Derivatives are financial contracts and instruments that derive their value from changes in some underlying asset, index, or rate. Derivative exposure is the positive

market value of derivative contracts that U.S. banks have with foreign counterparties.

favorable economic conditions in the 1990s and partly because of strengthened regulations

regarding the capital that banks are required to hold.

Also suggesting reduced risk for U.S. banks is that they have less exposure to emergingmarket countries in 2000 than they had in 1982. Exposure in such nations, whose markets

and financial structures are immature because their legal, fiscal, and financial systems are not

always stable and can be prone to problems, is frequently riskier than exposure in developed

countries.
x U.S. BANKS’ EXPOSURE TO FOREIGN FINANCIAL LOSSES

In contrast, it is unclear whether the growth of banks' foreign derivative exposure since 1982

implies greater risk for banks. Derivative exposure is not inherently riskier than traditional

lending exposure, but assessing the risk associated with it may be more complicated. The

leverage inherent in derivative exposure systemwide, as well as such exposure's concentration 

in the largest U.S. banks, adds urgency to understanding the risk it may pose. 

Perhaps the greatest danger associated with foreign derivative exposure is its inopportune

tendency to increase rapidly, both in amount and riskiness, during times of financial turmoil. For example, as the financial upheavals in Asian countries in 1997 intensified, U.S.

banks' derivative exposure in those nations shot up (largely because of currency devaluations)

at the very time that the risk associated with that exposure also increased. The fact that U.S.

banks ultimately were little affected by the problems in Asia does not by itself prove that

currently collected data are sufficient to assess the risks taken on by U.S. banks in foreign

markets.

Can the Risk of Foreign Exposure Be Better Assessed?

Whether, on balance, the changes in foreign exposure discussed above increase or decrease

risk to the banking system is difficult to determine. Data are lacking that would aid in that

assessment, particularly data on banks' growing foreign derivative exposure. For example,

only since 1997 have local country claims been reported by country and derivative claims

been included in total foreign exposure; no earlier data are available to help estimate trends

and assess potential risk. And derivative exposure is still not reported separately for local

country claims, which constitute nearly half of all foreign exposure. Banks' own riskassessment models may yield more-informative measures of their potential derivative exposure than are currently available in the public domain. 

Investors could benefit from the disclosure of foreign exposure by individual banking organizations: knowing the location and other details of a bank's foreign claims could help inform their decisionmaking. That information, perhaps accompanied by improved accounting standards or updated guidelines from the Securities and Exchange Commission, could

bolster market discipline by identifying banks whose foreign commitments might pose undue risk.

U.S. Banks' Exposure to

Foreign Financial Losses

As the lending operations of U.S. banks have become increasingly global over the past

two decades, concerns have heightened about the banks' foreign exposure and the ability of

regulators to monitor it. (U.S. banks' foreign exposure is the amount owed to them, or their

financial claims on, residents, businesses, and governments of other countries.) Those rising

concerns are linked to events in the early 1980s. At that time, U.S. banks faced a crisis when

several emerging-market countries ran into problems repaying their debts to U.S. commercial banks. The four nations—Mexico, Brazil, Venezuela, and Argentina—owed roughly

$37 billion to the eight largest U.S. banks, and that exposure represented about 150 percent

of the banks' capital and the reserve funds they hold to cover estimated losses.1

Federal bank regulatory agencies—the Office of the Comptroller of the Currency, the Federal Deposit Insurance Corporation, and the Federal Reserve—apparently viewed the debt

crisis of the early 1980s as a threat to the U.S. financial system as a whole and not just to the

banks that were directly affected. The regulators did not require the banks to write off their

large losses on the foreign loans immediately; instead, they allowed the banks to take about a

decade to clear their books of the bad debts. According to L. William Seidman, chairman of

the Federal Deposit Insurance Corporation from 1985 to 1991, bank regulators adopted

that policy of regulatory forbearance because to do otherwise might have caused seven or

eight of the 10 largest banks in the United States to be deemed insolvent, which could have

precipitated an economic crisis.2

 In that case at least, the foreign exposure of U.S. banks was

perceived to increase systemic risk—the danger that the failure of one bank could launch a

domino effect of failures throughout the financial system.

The vulnerability of U.S. banks to upheavals in foreign economies continues to be a matter

of concern to bank regulators and policymakers, particularly the banks’ exposure through
2 U.S. BANKS’ EXPOSURE TO FOREIGN FINANCIAL LOSSES

their holdings of a variety of financial instruments called derivatives. Derivatives are agreements to buy, sell, or swap future cash flows at prices that depend on changes in the value of

some other underlying security, index, rate, price, or commodity. For the most part, banks

use derivatives to hedge against losses arising from those changes and to lend stability to their

operations. But they may also use them to assume risk.

Banks' exposure through derivatives has grown in recent years. With that growth has come

some concern about over-the-counter (OTC) derivatives, many of which are not traded on

an exchange but are bilateral contracts made through dealers. In contrast to exchange-traded

derivatives, OTC derivatives lack formal, centralized mechanisms for trading and settling,

which may result in greater potential risk of default. Furthermore, OTC derivatives are customized contracts and thus have limited transparency. The specifics of some OTC agreements are known only to the parties involved and not to other investors or regulators—at

least, not at the time the initial transactions occur. That limited transparency makes it difficult to assess any risks that OTC derivatives may pose. Also of concern to regulators and

policymakers is that the OTC derivatives market is fairly concentrated among a group of

large, systemically important financial institutions that are globally interlinked by a web of

bilateral contracts extending virtually worldwide.

Direct lending in foreign nations as well as derivative contracts with foreign entities are affected by conditions in other countries that may expose banks to the risk of losses. Two key

questions that this paper seeks to answer are, first, how much risk are U.S. banks now taking

on, and, second, do current requirements for reporting on exposure provide regulators and

investors with sufficient information—in the first case, to allow regulators to assess the U.S.

banking system's vulnerability to disruption stemming from foreign markets, and in the

second, to allow investors to better discriminate among institutions and thus impose market

discipline through their investments and transactions?

Risks Associated with Banks' Foreign Exposure

Risk is present whenever future outcomes are uncertain. Risk can be described as a distribution of possible outcomes weighted by the probability of their occurring. The broader the

range of potential outcomes or the higher the probability of their being extreme, the greater

the associated risk. 

Banks face various types of risk. When a U.S. bank makes a loan to or enters into a derivative contract with a foreign party, the risks that the bank accepts are in most ways similar to

the risks it bears in any domestic loan or derivative transaction; they include credit risk,

market risk, and liquidity risk. A fourth type, country risk, is uniquely associated with foreign transactions. To manage such risks, banks have turned increasingly to derivatives.

3. Credit derivatives are often used to insure against or speculate on credit risk. For example, a credit default

swap is a derivative contract in which one counterparty pays periodic payments to a second for the right to

receive the face value of a bond in the event of the bond issuer's default.

A fifth type of risk, systemic risk, is the direct concern of regulators and policymakers rather

than of individual banks. Assessing and monitoring systemic risk has become a demanding

task as rising numbers of foreign transactions create significant interdependence among the

world’s financial markets. 

Credit Risk

Credit risk (also known as default risk) is the possibility that a borrower will not meet his or

her contractual obligations. For a traditional loan, credit risk is the possibility that a bank's

loan customer will not make timely interest or principal payments. For derivatives, that

concept extends to the risk that the other party in a derivative contract—the so-called

counterparty—will be unable to meet the contract's obligations. In recent years, banks have

begun to manage credit risk by using credit derivatives—contracts in which the payoffs depend partly on the creditworthiness of one or more commercial or governmental entities.3

Banks analyze the credit risk of potential borrowers or derivative counterparties along several

dimensions. They look at the borrower's reputation, which is usually measured by credit

history or credit rating. They also investigate the borrower's ability to make the payments

required on the loan on the basis of projected income, and they consider borrowers' financial

reserves and sometimes their collateral. (Collateral is an asset pledged to the bank in the

event that the borrower defaults; it is sometimes used to reduce credit risk.) General economic conditions may also have a bearing on whether borrowers can meet their obligations

and may also affect other categories of risk discussed later. 

Banks can never entirely eliminate credit risk, and some level of defaults on loans or derivative contracts is inevitable. Among investments available in the United States, only securities

issued by the U.S. Treasury are considered free from the risk of default. The safety of those

securities is bolstered by the size and strength of the U.S. economy combined with the full

faith and credit of the U.S. government, which has the power to tax its residents, if necessary, to pay interest and principal. However, banks generally seek to invest their funds in

instruments with higher yields than those offered by Treasury securities, and they can obtain

such yields only by making relatively riskier loans and investments. Many analysts contend

that competitive pressure has led U.S. banks in recent years to accept ever-greater credit risk

in both their foreign and domestic activities. That increased pressure has come in part because banks have lost some of their best borrowing customers as more large corporate bor-

Stability (Washington, D.C.: AEI Press, 1996).

rowers choose to bypass bank loans and draw directly on capital markets by issuing their

own stock or marketable debt.4

Market Risk

Market risk is the possibility that the value of assets or liabilities will change because of ups

or downs in their prices. It is a standard measure of risk in the financial world in part because it is easier to quantify than are many other types of risk: analysts can examine past

changes in prices and so calculate the variance of returns. (Variance is a statistical measure of

the extent to which returns differ from the average over some period.) The greater that variance, the greater the market risk—that is, the greater the likelihood that returns may swing

widely in the future. The volatility of prices or returns has traditionally been used as a proxy

for market risk. Accordingly, some analysts refer to market risk as price risk.

Internationally active banks may face significant market risk from changes in foreign exchange rates. In particular, institutions that are dealers in foreign exchange or that hold assets

or liabilities denominated in various currencies may be exposed to gains or losses from movements in exchange rates. Banks often try to hedge their foreign exchange risk by using foreign exchange derivatives; they also use statistical models to measure and manage market risk

(see the later discussion).

Liquidity Risk

An asset is said to be liquid if it is readily convertible to cash with a minimal loss in value. In

a liquid market, sellers of an asset can quickly find buyers willing to pay a price for it that

comes close to its current price. U.S. Treasury securities are an example of liquid assets—the

market for them is deep (many buyers and sellers), so they can be easily traded at virtually

any time and in large quantities with little effect on their prices. 

When a financial institution holds assets that are liquid, it is able to meet unexpected demands for cash by selling some of them. A bank or other financial entity bears liquidity risk

when it holds illiquid assets. If it has to meet demands for cash, it may have to sell the assets

at a loss; if the market is very illiquid, it may not be able to sell them at all.

Liquidity risk is not as easy to quantify as is credit or market risk, and there is no commonly

accepted way to measure it. In fact, liquidity risk points to a shortcoming of focusing simply

on price volatility (or market risk) as the indicator of overall risk. For example, because
U.S. BANKS’ EXPOSURE TO FOREIGN FINANCIAL LOSSES 5

illiquid assets are infrequently traded, they could show relatively little variance in a series of

data on prices over time. Thus, a measure of the volatility of such assets might make them

appear rather safe, even though attempts to sell them in a deteriorating market could result

in sharp drops in their prices and possibly substantial losses for their owners.

Country Risk

The term "country risk" denotes the difficulties that banks may confront, as a result of some

development in another country, in collecting what is owed to them from borrowers there.

The development could be political or economic; or it could be a combination of the two,

since dire economic conditions may lead a foreign government to act in a previously unanticipated way.

Part of country risk is the possibility that the actions of a foreign government will impede

repayment of money owed to foreigners. Central banks typically hold currencies of many

foreign countries to facilitate international finance and trade. If a foreign country's holdings

of U.S. dollars are low, for example, its government may prohibit any further repayment of

debt to outside creditors in dollars. If a foreign borrower's loan or derivative contract specifies payment in dollars, the government's action may force that borrower to default, even

though, when considered on its own, the borrower appears to be a good credit risk. Or, as

another example, a foreign government that had borrowed money from a U.S. bank might

be overthrown, and the successor government might refuse to repay the loan. In either case,

a lender’s legal remedies to recoup the money it is owed are very limited.

In addition to the risk of governmental actions that impede debt repayment to foreigners,

the credit risk associated with borrowers and derivative counterparties in foreign nations has

become an increasingly important component of country risk. If a foreign economy suffers a

sudden downturn, for example, all borrowers and counterparties in that country may be at

increased risk of defaulting on their obligations. And should a foreign counterparty default

on its obligation to a U.S. bank, the foreign legal system might not compel payment.

Systemic Risk

The confluence of high levels of market, credit, and liquidity risk may amplify potential

systemic risk. As noted earlier, systemic risk is the possibility that the failure of one financial

institution to meet its obligations to other banks will trigger a chain reaction, depriving

those banks of expected funds and preventing them from settling their transactions (broadly

speaking, collecting what is due them and paying what they owe). Carried to its logical extreme, such a series of events could mean that institutions that had no business dealings with

a failed bank would ultimately be affected in a general shutdown of banks' normal clearing

and settlement operations—in other words, payment-system gridlock. Moreover, the in-
6 U.S. BANKS’ EXPOSURE TO FOREIGN FINANCIAL LOSSES

creasing globalization of financial markets raises the possibility that financial failures in one

country will be transmitted around the world. That kind of risk to the functioning of the

global financial system is a primary concern of policymakers and regulators. 

Managing Risk

One reason that banks have used derivatives more and more in recent years is that those

contractual arrangements allow various types of financial risks to be "unbundled" and transferred. Through derivative transactions, banks may either take on or shed risk. The term

"risk management," for bankers and others in the financial services industry, encompasses

using derivatives to both speculate (assume risk) and hedge (reduce risk).

Broadly speaking, when banks hedge, they make offsetting transactions that limit their losses

but also restrict their gains. For the most part, banks use derivatives for hedging rather than

speculating. For example, they may hedge against changes in exchange rates. Say that a bank

knows that it will receive a million British pounds in three months (perhaps as payment on a

loan) and wants to avoid the risk that changes in the dollar/pound exchange rate between

now and then could cause it to lose money when it converted the pounds to dollars. The

bank could hedge its "position" by entering into an agreement today to sell the pounds in

three months at a specified rate of exchange—for illustration's sake, 1.4 dollars per pound.

The agreement ensures that in three months, when the bank receives the 1 million pounds, it

will be able to sell them for 1.4 million dollars, whether or not the prevailing dollar/pound

exchange rate has shifted. 

Speculators use derivatives to take on risk with the expectation of commensurately higher

profits. Indeed, the potential for gain (or loss) may be relatively unlimited for speculative

investments. Suppose, for example, that a speculator believes that the U.S. dollar will weaken

relative to the British pound; that is, one pound will buy more dollars in the future than it

does now. If the current three-month-forward dollar/pound exchange rate is 1.4 dollars per

pound, the speculator could take the other side of the transaction described above—that is,

contract to buy 1 million pounds for 1.4 million dollars in three months. If the dollar weakens relative to the pound to such an extent that three months from now, a pound can be

exchanged for 1.5 dollars, the speculator can buy 1 million pounds for 1.4 million dollars

and then immediately sell them for 1.5 million dollars, clearing a profit of $100,000. However, if the dollar strengthened relative to the pound and the exchange rate was 1.3 dollars

per pound, the speculator would lose money.

Identifying the purpose of a given derivative transaction is generally difficult because the

reports that banks are required to make do not distinguish between gains from hedged positions and gains from speculative ones. That lack of distinction reduces the ability of inves-

tors—and, to a lesser extent, of regulators—to assess a bank’s risk exposure since the two

kinds of positions are susceptible to different degrees of risk. Moreover, intention aside, a

position hedged with respect to market risk may nevertheless be subject to credit, country,

and liquidity risk.

How Foreign Exposure Is Measured and Reported

Central to any analysis of the foreign exposure of U.S. banks is the availability of reliable

data. Yet the span of measuring and reporting on banks' foreign claims is relatively brief—

approximately the past two decades. Lawmakers became concerned in the 1970s about the

buildup of banks' financial claims in emerging-market countries and held hearings to assess

the risk those claims posed for banks.5

 They found little information, which spurred bank

regulators to begin in 1977 to collect data on banks' foreign exposure. The Congress codified that collection requirement in the International Lending Supervision Act of 1983; the

law calls on banks with foreign exposure to report quarterly to regulators and to publicly

disclose "information regarding material foreign country exposure in relation to assets and to

capital."6

 Regulators began providing that information to the public in 1984 through the

Country Exposure Lending Survey (CELS), which is published by the Federal Financial

Institutions Examination Council.7

Changes made to the CELS in 1997 increased the level of detail that the report provides.

Those improvements allow regulators and investors to better assess the locations and types of

banks' foreign claims and banks' vulnerability to losses. 

Overview of the CELS

The CELS reports data on U.S. banks' foreign exposure by the country in which claims

originate, but at varying levels of detail. At the most general level, it provides aggregated

data—that is, for all reporting banks. In no instance does it report data by individual bank.

All banks chartered in the United States that have at least one foreign branch or foreign

subsidiary and at least $30 million in consolidated claims on non-U.S. residents must report

for the CELS. In 1982, 171 banking organizations met those criteria. In December 2000,

partly because of mergers and consolidations, 99 organizations met them. 
8 U.S. BANKS’ EXPOSURE TO FOREIGN FINANCIAL LOSSES

8. In addition to the foreign exposure defined and discussed in this paper, banks may have indirect exposure,

which is not measured. For example, when a bank lends to a U.S. multinational corporation, the bank in

some sense is also exposed through its loan to developments in other countries. However, since the

corporation is subject to U.S. bankruptcy laws, there is less uncertainty about repayment than in cases in

which a U.S. bank lends directly to foreign governments or to private foreign entities.

Regulators also break down the overall totals on foreign exposure to report data by bank

group and by type of claim. Reporting banks fall into one of three categories: money center

banks (a collection of the largest U.S. banks, which over time has shrunk from nine to five in

number as a result of mergers, but which has grown in assets as the banking sector consolidated), other large banks, and all other reporting banks. For each bank group, the CELS

reports two categories of foreign exposure: cross-border claims and local claims, which are

differentiated—as their titles imply—by whether or not they originate at a U.S. bank's office

in the country of the foreign entity that bears the claim.8

Cross-border and local claims are distinguished as well by the way they are reported in the

CELS. Cross-border lending exposure is reported by bank group and by country of borrower. It is further broken down into three categories of borrowers: foreign banks, foreign

governments, and private nonbank borrowers. (For the sake of expediency, cross-border

claims excluding derivative exposure, which is discussed in the next section, are referred to in

this paper as cross-border lending exposure, even though those claims include more than just

loans.)

Measuring a bank's cross-border lending exposure is not as simple as totaling its lending by

the country of residence of borrowers. In some cases, the borrower has a guarantor in another country that is the ultimate source of repayment; consequently, the bank's exposure

may actually be to conditions in a country other than the one in which the direct borrower is

located. In reporting, banks allocate their exposure to the country of ultimate responsibility.

As an example, for purposes of reporting, bank branches and agencies carry the credit guarantee of their head office. Thus, if a U.S. bank made a loan to a branch of a Japanese bank

located in South Korea, it would report that exposure as a claim in Japan, not South Korea.

Local claims now constitute nearly half of U.S. banks' total foreign exposure; knowing the

countries in which those claims originate is important for gauging the risks that banks are

facing. Before 1997, those claims were denoted as "local currency claims"—that is, claims in

that country's currency—and were reported as a single worldwide total. Beginning in 1997,

regulators altered the name to "local country claims" and changed the definition to include

local claims denominated in currencies other than the local one. (In some Latin American

countries and in other parts of the world, the major "other currency" for local claims is the

11. The present value is a single number that expresses the flow of current and future income or payments as an

equivalent lump sum received or paid today. In an interest rate swap, for example, in which two parties

agree to exchange streams of interest payments based on a notional amount of principal for a predetermined

U.S. dollar.) Thus, the CELS's revised definition of local claims now provides better information on the risks that banks may be taking on, because it hinges on where the claim originated rather than the currency in which it is denominated and includes dollar-denominated

obligations originating at bank offices in the foreign country.

Given the growth over the past two decades in banks' use of derivatives, the decision by

regulators in 1997 to start reporting foreign derivative exposure improved the CELS. Again,

that dimension of reporting differs for cross-border and local country claims: the CELS

reports cross-border derivative exposure separately, by country, but it does not break out the

derivative component of local country claims. The complexity of many derivative transactions and the interconnections among markets and nations that they often represent suggest

that many U.S. banks—especially large ones—may be subject to substantial risk through

their derivative contracts.

Reporting Derivative Exposure

Some forms of derivatives, such as commodity options and forward contracts, have been

available for a long time, but since the mid-1980s, derivatives' variety and volume have

grown markedly (see the appendix).9

 Correspondingly, banks' exposure to potential losses

through financial derivatives was minimal in 1982; by 1986, it had become significant.10 By

1997, when cross-border derivative exposure was first reported in the CELS, it accounted for

about one-third of banks' total cross-border exposure.

At least one reason that it took so long for regulators to begin requiring banks to report their

foreign derivative exposure is the difficulty of measuring it. Derivatives do not lend themselves to traditional accounting principles and practices in which banks report their assets

and liabilities on their balance sheet at the original transaction value, or "historical" cost.

Not only does that cost frequently have little relation to the future cash flows associated with

a derivative contract, but in some cases, such as in an interest rate swap, the derivative contract is neither an asset nor a liability at the time it is entered into because its net present

value is zero.11
10 U.S. BANKS’ EXPOSURE TO FOREIGN FINANCIAL LOSSES

period, the swap transaction is typically arranged at current market rates so that the net present values of

payments to each party are equal. However, the value of a derivative contract changes as the value of the

instrument it is derived from changes—in this case, the "instrument" is the behavior of interest rates. At

some point, the interest rate swap may be an asset to one of the parties, earning money on balance; at

another time, it may be a liability, requiring the net payment of money.

12. See John Kambhu, Frank Keane, and Catherine Benadon, "Price Risk Intermediation in the Over-theCounter Derivatives Markets: Interpretation of Global Survey," Economic Policy Review, Federal Reserve

Bank of New York (April 1996), Table 1.

Lacking a better measure of exposure, banks initially reported the size of many of their derivative holdings, particularly their swaps, as the "notional principal"—that is, the amount of

principal on which the periodic payments specified in the derivative contract are based. (In

an interest rate swap, for example, the notional principal is the value of the loan on which

interest is calculated.) Those amounts appeared as footnotes on a bank's financial statements, but by the mid-1990s, they were strikingly large, totaling trillions of dollars for all

internationally active banks.12 Although notional principal gives some sense of the size of a

derivative contract, it is not a good measure of exposure—the amount of money at risk—

because it never changes hands. What is at risk are the payments based on that notional

amount.

Dissatisfaction with the way banks accounted for derivatives helped move accounting practices for those instruments toward measures based on market values. Since 1994, the Financial Accounting Standards Board, the organization that sets accounting standards for the

private sector, has established rules that significantly expand what financial and nonfinancial

companies must disclose about their use of derivatives. Bank regulators also expanded reporting requirements for all banking organizations effective in 1995; the requirements include, among other things, reporting the market value of derivatives. Those efforts were

intended to make derivatives more transparent, presenting relevant information in a way that

allows the public and regulatory authorities to make informed judgments about a firm's

derivative exposure.

A further complication in evaluating foreign exposure resulting from derivative contracts

concerns appropriate netting—that is, how banks take offsetting claims into account so that

the exposure they report is the net amount owed to them. Most derivative contracts written

by banks state that if a counterparty defaults on one derivative contract with a particular

bank, it must terminate all such outstanding contracts with the bank. If an institution has

several derivative contracts with a particular counterparty, some of the contracts may have

negative value at any one time and some may have positive value to the bank. If that

counterparty should default, the bank's exposure would be the net of the counterparty's
U.S. BANKS’ EXPOSURE TO FOREIGN FINANCIAL LOSSES 11

13. Netting agreements involving some foreign countries may not be considered legally enforceable. 

Consequently, the CELS may report some exposures with a single counterparty that are not netted.

14. Revaluation gains can also be thought of as the positive replacement value of a derivative contract—that is,

the amount that a bank would have to pay a new counterparty to accept that contract in the event that the

original counterparty defaults.

outstanding contracts. The data reported in the CELS are netted for transactions with the

same counterparty, as long as the bank has a legally enforceable master netting agreement

with it.13

For the moment, bank regulators have settled on revaluation gains as the measure of derivative exposure. Such gains are the market value of a U.S. bank's derivative contracts in which

foreigners owe positive amounts to the bank. In simple terms, revaluation gains represent the

amount that should flow to the bank if it liquidates all of its positive-value derivative contracts with foreign counterparties.14

How U.S. Banks' Foreign Exposure 

Has Changed Since 1982

Some of the changes that have occurred in U.S. banks' total foreign exposure over the past

two decades bode well for banks' financial stability. Although exposure has increased in both

real (inflation-adjusted) and nominal-dollar terms, it has diminished relative to capital

(mostly because banks' capital has grown). Moreover, in contrast to the early part of the

period, banks' foreign exposure now is largely centered in less risky, more developed countries.

Nevertheless, three developments contribute to some uncertainty about banks' current financial risks. First, their foreign exposure today comprises more claims on private nonbank

parties than on governments or on other banks, and such parties might be more likely than

governments or banks to default in times of financial turmoil. Second, local country claims

are growing, possibly as a result of some banks stepping up their retail banking activities in

foreign countries. Those claims may include a high percentage of relatively riskier derivative

transactions, but that cannot be determined because banks are not required to separately

report local country derivative exposure for the CELS. Third, the level of risk associated

with derivative exposure is unclear. Such exposure tends to rise during times of financial

crisis, and although it could represent hedging activity, which would tend to reduce risk,

some of it might reflect riskier positions. Moreover, even when the intent of that exposure is

to hedge against losses, turbulent financial conditions tend to increase the danger that a

foreign counterparty may default.

the Country Exposure Lending Survey was changed from local currency claims to local country claims in 1997 because

some countries, particularly in Latin America, conduct local transactions in U.S. dollars. Local country claims (which

can be denominated in any currency) are amounts owed by foreigners that originate at the offices of U.S. banks in the

foreigners' home countries. Derivatives are financial contracts and instruments that derive their value from changes in

vulnerability to it has changed. An additional indicator is the ratio of foreign exposure to

bank capital. The capital of a bank is a measure of its financial strength and a cushion 

against losses.15 Because bank capital has increased since 1982 (owing to both the strength of

the U.S. economy in the 1990s and the implementation of risk-based rules for the capital

that banks must maintain), foreign exposure relative to capital has been declining (see

Figure 2).16 In 1982, foreign exposure was more than six times the total capital of banks

contracts.

involved in any foreign lending; as of December 2000, the ratio of foreign exposure to the

total capital of banks with any foreign exposure was slightly less than twice total capital.

That reduction suggests an improvement in overall safety, assuming that the banks' other

assets and their foreign exposure have not become riskier.

Another indication of the risk that U.S. banks' foreign exposure represents is the level of

development of the countries in which that exposure occurs. Exposure in other developed

countries such as Germany, Japan, and the United Kingdom is considered less risky than

exposure in emerging-market countries because in general, developed countries reliably enforce contract and bankruptcy laws. Currently, the bulk of U.S. banks' foreign exposure is in

other developed countries (see Figure 3). Indeed, by the end of 2000, less than one-fourth

was in emerging-market nations (see Figure 4).

Cross-Border Lending

In real terms, U.S. banks had less cross-border lending exposure in 2000 ($382 billion) than

they had in 1982 ($531 billion), and their exposure in 2000 was located in less risky, more

developed countries. Since 1992, however, cross-border lending exposure has been rising

and has become increasingly concentrated in the money center banks (see Table 1). In 1992,

money center banks accounted for less than 60 percent of banks' total cross-border lending

exposure; their share in December 2000 was 75 percent.

The regional composition of cross-border lending exposure has also changed since 1982 in

that banks' lending to emerging-market countries has declined. By the end of 2000, such

countries accounted for just 19 percent of U.S. banks' cross-border lending, compared with

a share of 39 percent in 1982 (see Table 2 on page 18). In 2000, for example, borrowers

from African, Latin American, and Asian countries claimed both smaller percentage shares

and smaller total dollar amounts of lending than they did in 1982. Those shifts have probably lessened the risk associated with U.S. banks' cross-border lending because lending in

emerging-market countries is generally riskier than lending in developed countries.

Data on cross-border exposure include information on the type of borrower—whether it is a

bank, a government entity, or a private nonbank borrower. The data show that the share of

exposure to private nonbank entities has increased over the years, rising from 28 percent of

Local Country Claims

From 1982 to 1995, local country claims as a share of total foreign exposure rose from 18

percent to a peak of 42 percent. Since 1998, they have hovered around 40 percent (see Figure 5). As of December 1997, the CELS has broken down local claims by country, and

through December 2000, about one-third of such claims were in emerging-market countries

(see Figure 6 on page 20). Today, local country claims make up a slightly higher proportion

of banks' total foreign exposure in emerging-market countries than they do in developed

countries. As noted earlier, revaluation gains on derivative contracts are now part of the

overall totals of local country claims reported in the CELS.

Whether local country claims are riskier than cross-border claims is difficult to determine.

On the one hand, local country claims may be less risky, particularly if the claim is denominated in the local currency. Foreign exchange crises sometimes lead governments to restrict

payments on cross-border claims, but local country claims in the local currency are in many

cases not affected. On the other hand, local country loans denominated in U.S. dollars at a

bank's office in a foreign country may carry more risk, especially if such loans are made to

borrowers whose income is not denominated in U.S. dollars. Furthermore, U.S. bank

branches in foreign countries are subject to those countries' laws, which may also affect the

riskiness of local country claims. For example, the Argentine government recently forced

22 U.S. BANKS’ EXPOSURE TO FOREIGN FINANCIAL LOSSES

Derivative Exposure

In real terms, U.S. banks' cross-border exposure measured as revaluation gains on derivatives

has ranged between $81 billion (in March 2000) and $123 billion (in December 1997) since

reporting began in June 1997 (see Table 3). In all quarters of those years, the majority of

that exposure was in developed countries. For example, as of December 1998, counterparties

in developed countries owed U.S. banks $106 billion (in 1996 dollars) as a result of revaluation gains on derivatives; in contrast, counterparties in emerging-market countries in Asia

owed about $5 billion, and Latin American counterparties owed about $2 billion. Counterparties in "banking centers" (such as Hong Kong, Singapore, and the Cayman Islands) owed

$3.8 billion.

Of course, those figures denote only cross-border derivative exposure and not all foreign

exposure through derivatives. Moreover, the trend of total foreign exposure is further disjointed because no data on exposure from derivatives were reported before 1997 (see Table

4). Yet the view of the change in total foreign exposure presented in Table 4 is largely accurate because the exposure of U.S. banks that is attributable to derivatives was minimal in

1982. With derivatives included, total foreign exposure at the end of 2000 stood at $782

billion (in 1996 dollars).

The data allowing after-the-fact analysis of the Asian crisis of 1997 show that the marketvalue measure of derivative exposure—that is, revaluation gains—can change rapidly, without forewarning. Thus, those gains do not accurately reflect the potential future value of

banks' derivative contracts and provide policymakers with only a poor measure of foreign

risk exposure. 

Why Derivative Exposure Increases During Financial Turmoil. Data from 1997 demonstrate that during a foreign financial crisis, banks' cross-border lending exposure tends to

creep down and their cross-border derivative exposure tends to shoot up. Why does that

happen? In general, foreign exposure alters when two factors change: the market value of

banks' existing loans and derivative contracts and the pace of new lending and contracting. If

existing cross-border lending in a country is denominated in U.S. dollars and the country's

currency is devalued relative to the dollar—which frequently happens in a foreign financial

crisis—the contractual amounts owed to U.S. banks do not change (although the burden on

debtors will be greater, because they will owe more in terms of their local currency). When

cross-border lending is denominated in the local foreign currency, the dollar value of foreign

exposure will decline if the foreign currency is devalued. Consequently, the foreign currency's devaluation tends overall to reduce cross-border lending exposure, but that effect will

be weakened to the extent that cross-border lending is denominated in dollars.

NOTE: U.S. banks' foreign exposure is the amount owed to them by (or their financial claims on) residents, businesses, and

governments of other countries. The total foreign exposure of U.S. banks is the sum of their cross-border and local

country claims, both of which include derivative exposure. Cross-border claims are amounts owed by foreigners that

originate outside the foreigners' home countries, usually at a U.S. bank's head office in the United States. Local country claims are amounts owed by foreigners that originate at the offices of U.S. banks in the foreigners' home countries. 

Derivatives are financial contracts and instruments that derive their value from changes in some underlying asset,

index, or rate. Derivative exposure is the positive market value of derivative contracts that U.S. banks have with foreign

counterparties. Derivative exposure may be both cross-border and local country, depending on where the derivative

contract originates.

when they mature. Under such conditions, reported foreign exposure may also decline

because lending banks write off claims on borrowers when the prospect of repayment looks

dim. 

Changes in exchange rates or interest rates affect banks' exposure through derivatives differently than they affect exposure through lending. Banks may try to lessen their derivative

exposure by reducing the number and amounts of their contracts, but unlike their lending,

what they owe on the contracts may increase sharply during financial upheavals as a result of

wide swings in the variables underlying the contracts. Before a crisis, many derivative contracts may have values close to zero; that is particularly true of swaps (for which, as noted

earlier, the net present value of the contract at its inception is zero). When a crisis erupts, the

18. Not all components of cross-border lending exposure were necessarily marked to market (valued at market

prices). Thus, the market value of such exposure may have dropped by more than the CELS data indicated. 

In that case, there would be even more disparity between changes in lending exposure and changes in

derivative exposure during foreign financial crises.

contracts' values may shift dramatically—revaluation gains may zoom from zero to millions

of dollars.

As intermediaries, or middlemen, in the derivative market, banks usually try to balance their

exposure to shifts in exchange or interest rates by taking both sides of derivative positions.

Consequently, changes in those rates associated with a foreign financial crisis will lead to

revaluation gains for the banks on some contracts and losses on others. Indeed, banks count

on the gains to offset the losses. The problem with the increased derivative exposure triggered by deteriorating economic conditions is the correspondingly greater risk that the

counterparty owing money to the U.S. bank may default. Of course, the increased risk of

default applies to banks' foreign lending exposure as well.

Volatility of Derivative Exposure During the Asian Crisis. Before the Asian financial

crisis in 1997 and 1998, U.S. banks' cross-border derivative exposure in emerging-market

nations in Asia was a small component of their total foreign exposure. In the last half of

1997, however, their derivative exposure rose dramatically on a percentage basis. Banks'

exposure through cross-border derivative contracts in Hong Kong, Indonesia, Korea, Malaysia, the Philippines, Singapore, and Thailand measured as a percentage of total cross-border

exposure in those countries jumped from 10 percent to 30 percent between June 1997 and

December of that year (see Figure 7). 

In dollar terms, the amount owed by counterparties in Thailand, for example, went from

$417 million to $2.5 billion (see Figure 8). In both Singapore and Indonesia, derivative

exposure increased more than fivefold over a span of three to six months at the onset of the

crisis. And in South Korea, where U.S. banks' total exposure was fairly large, the amount

owed to them by South Korean entities through cross-border derivative contracts more than

tripled between September 30, 1997, and December 31, 1997, rising from $1.3 billion to

$4.7 billion. 

In comparison, U.S. banks' cross-border lending exposure during the crisis period edged up

modestly or declined. For example, such exposure in Thailand dropped by more than 35

percent.18

The years of the Asian crisis saw U.S. banks' derivative exposure increasing with counterparties all over the world, not just in Asia. The amounts owed to the banks as a result of

June 1997, peaked at $123 billion in December 1997 (both numbers are in 1996 dollars),

and then fell to lower levels by 1999 (see Table 3 on page 21). The pattern is more pronounced when just the amounts owed by emerging-market countries are considered. That

derivative exposure more than doubled from June 1997 to December 1997, before retreating

over the next six quarters. The data also show the spread of instability across regions. The

rise-and-fall pattern was first evident in Asia in the second half of 1997; it later appeared in

Eastern Europe and Latin America, roughly coinciding with currency devaluation and economic declines in each region. 
U.S. BANKS’ EXPOSURE TO FOREIGN FINANCIAL LOSSES 27

Can the Risks of Foreign Exposure Be Better Assessed?

Since the early 1980s, financial markets have become both globally integrated and more

complex. Those developments have made assessing banks' vulnerability to losses in international financial markets, particularly their exposure through derivative holdings, both more

important and more difficult. The current measure of derivative exposure, revaluation gains,

has some limitations as an assessment tool. Moreover, several other factors make risk assessment particularly challenging—the correlation of different types of risk, the lack of transparency in the over-the-counter derivative market, the inherent leverage in derivative exposure,

and the additional complexity that indirect exposure brings. As a result, what derivative

exposure means for banks' systemic risk is unclear.

Banks have implemented a number of techniques to assess risk, including the evaluation of

potential future exposure and the use of value-at-risk models and stress testing. Some observers have proposed that banks improve their reporting of exposure by disclosing the results of

their assessments. Other improvements mentioned in the debate include changing the Country Exposure Lending Survey to report on specific banks and requiring banks to provide

more-detailed exposure information for publication in the survey.

Challenges in Assessing Derivative Exposure

The speed at which the markets for derivatives grew during the 1980s and 1990s initially

outpaced the ability of regulators, investors, and the banks themselves to evaluate how those

new markets would affect the risk borne by individuals, firms, and the financial system as a

whole. In recent years, large banks have worked hard to assess those risks. But the markets'

complexity as well as several specific factors makes that task difficult, not only for banks but

for regulators and investors also.

First, market (or price) risk, credit risk, and even liquidity risk are often correlated, and

hedging for one does not necessarily avert another. Risks can snowball; for example, increased market risk can trigger increased credit risk. A bank may have a hedged position in a

derivative contract with respect to market risk, but when prices change suddenly so that the

foreign counterparty owes the bank money, that is precisely when the counterparty's creditworthiness may plummet and it may default. Credit risk may also be amplified by liquidity

risk. If counterparties on the losing side of a derivative contract are unable to sell assets without depressing the assets' prices (or if liquidity dries up completely and they are unable to

sell their assets at all), their risk of default may rise.

The lack of transparency in the over-the-counter derivative market is a second factor that

clouds the picture of banks' foreign exposure. Unlike the established exchanges, the OTC

derivatives market is a dealers' market and lacks formal, centralized limits on individual

positions or leverage (the financing of investment at least partly with borrowed money), as
28 U.S. BANKS’ EXPOSURE TO FOREIGN FINANCIAL LOSSES

19. Leverage is inherent, for instance, when a bank does not need to commit as much money to enter into a

derivative contract as it would have required to buy the underlying asset. Of course, derivative exposure can

be further leveraged by borrowing money to take on derivative contracts.

20. See Franklin Edwards, "Hedge Funds and the Collapse of Long-Term Capital Management," Journal of

Economic Perspectives, vol. 13, no. 2 (Spring 1999), p. 202.

well as rules and mechanisms for ensuring that the market will remain stable. Information

about who owns which risks is unavailable for the most part, making it difficult for derivative counterparties to monitor one another effectively. However, participants in the market

can generally exert some discipline and affect its operations by choosing not to transact or by

limiting their exposure to certain counterparties. For those reasons, some observers believe

that the information currently provided to investors and participants in the OTC derivative

market is adequate.

The leverage inherent in derivative exposure is a third factor that makes risk assessment difficult. Leverage amplifies the profits or losses that result from a derivative contract, but it

cannot be determined from the CELS data.19 An example of the leverage inherent in derivative contracts is an interest rate swap in which the amount of exposure to changes in interest

rates is largely determined by the notional size of the contract. If the parties to the contract

want the payments to be large, even for small changes in rates, they specify a large notional

value, which determines the implicit leverage.

A fourth factor, indirect exposure, introduces additional complexity. Just as U.S. banks'

foreign lending exposure may be indirect (for example, loans to U.S. multinational corporations), so their exposure through financial derivatives may be, as borrowers themselves enter

into derivative contracts and thus add to their lenders’ exposure in derivative markets. Indirect exposure is not necessarily captured in any regularly reported data. Yet it may be particularly risky because U.S. banks count among their customers "highly leveraged institutions,"

a subset of which are commonly called hedge funds. Hedge funds are unregulated with regard to the investments they make. The exposure from such loans may compound the risk

that a bank faces if the bank's investments in derivatives mirror those of the parties to whom

the bank lends. Some observers have indicated that such piggybacking was among the problems that surfaced with the failure of Long-Term Capital Management (LTCM) in 1998.20

The web of interconnections among counterparties may increase systemic risk, but the complexities of the derivative markets make such risk difficult for regulators to evaluate. On the

one hand, if a major participant in the markets defaulted on its contracts, it might cause

others to default, and what began as an isolated occurrence could give rise to systemic problems that threatened the solvency of key market participants. (That scenario was evident in
U.S. BANKS’ EXPOSURE TO FOREIGN FINANCIAL LOSSES 29

21. Ibid., p. 199. After it became known that LTCM might default, some dealers were concerned that their

counterparties were heavily exposed to the hedge fund. A liquidity run quickly ensued, as market

participants tried to shed risk with LTCM and replace their positions with risk-free U.S. Treasury securities.

In response to deteriorating market conditions, the Federal Reserve acted to increase liquidity in financial

markets, cutting interest rates twice within two weeks in the autumn of 1998 and then a third time at its

regular Federal Open Market Committee meeting in November.

the now classic example of LTCM.)21 On the other hand, interconnections and complex

markets might allow risk to be placed with the parties that were most prepared to accept it,

which might help stabilize the financial system. As things stand now, the question of

whether the growth of derivative markets has increased or decreased systemic risk remains

unanswered.

Disclosure of Banks' Risk Assessments 

The techniques and computer models that banks use today to assess and manage risk are a

substantial improvement over earlier methods. Though far from perfect, the new measures

go beyond simple market-value assays of exposure (see Box 1); they are forward-looking and

attempt to assess the consequences for a bank of low-probability but high-loss outcomes.

Such techniques may be useful in overcoming at least some of the difficulties in assessing the

risk inherent in derivative transactions and thus in U.S. banks' foreign exposure.

In pursuit of that goal, international banking regulators have recommended that banks provide information on the techniques they use or, at the least, disclose the actual assessments

those methods produce. For example, a major focus of the Basel Committee on Banking

Supervision's new capital accord is to bolster the discipline that investors' transactions can

impose on markets by calling on banks to more fully disclose the internal methodologies

they use to assess and mitigate credit risk.22 In addition, the Multidisciplinary Working

Group on Enhanced Disclosure (a joint venture of four international organizations that

regulate financial services) has also recommended that financial intermediaries such as banks

disclose a number of measures of their relevant financial risks.23 The group's final report

urged both qualitative and quantitative disclosures, stressing that the information should be

expressed in ways "consistent with firms' own risk-management practices." The group also

advocated that banks disclose the efficacy of those practices.

Box 1.

Risk-Quantification Techniques

The ultimate goal of risk-measurement techniques is to estimate the distribution of the

future returns from (or values of) a given portfolio of assets. The range of possible changes

in the prices of those assets and the probability of each change’s occurring make up the

portfolio's risk profile. Measures of potential future exposure, value-at-risk models, and

stress testing are some of the risk-quantification techniques used by many banks today.

Potential future exposure estimates the future replacement cost of a derivative contract—in

other words, how changes in the underlying instrument or index would affect the contract's

value over its remaining term. Risk managers for banks may use probability analysis in the

form of simulation studies, option pricing models, or other statistical methods to generate

measures of potential future exposure. The analysis generally involves modeling the volatility of the underlying variables that affect the derivative contract's value. Various values may

be calculated, such as the expected (or average) potential future exposure and the maximum

(or worst-case) exposure.

Value-at-risk (VaR) models measure market risk by estimating, at a given level of statistical

confidence, the maximum amount that a bank can expect to lose under normal market

conditions over a specified time. In essence, the value-at-risk calculation attempts to make a

statement of the form "We are X percent certain that we will not lose more than V dollars in

the next N days";1

 it gives banks a single, bottom-line figure measuring their potential loss

(V, in the previous sentence), which can be compared among different types of trading

portfolios. VaR models generally use historic price volatility to estimate possible losses. The

models are best at measuring typical losses (those that could be expected to occur on the

order of 95 or 99 times out of 100). But as with all models based on historical data, they are

less useful in estimating how large losses might be in the case of unusual or unprecedented

events. Efforts are under way to adapt value-at-risk concepts to incorporate credit and

liquidity risk.

Stress testing focuses on the lower end of a distribution of returns from a portfolio's assets.

Stress tests simulate catastrophic financial events, such as the most extreme historical shocks

to the financial markets over the past 10 or 20 years. They then assess how such extreme

movements of the market might change a portfolio's value. Stress testing is a way to take

into account extreme events that have a small probability of occurring but that do arise

from time to time.

Some observers have proposed other ways to help regulators, investors, and creditors to

better assess the risk posed by banks' foreign exposure. For example, the President's Working

Group on Financial Markets recommended that banks be required to measure and report on

leverage.24 There are many ways to measure it; most informative would be a gauge that incorporates the inherent leverage in the positive replacement value of derivative contracts. 

Still unclear, however, is the usefulness of banks' disclosing additional detail on their foreign

derivative exposure garnered through techniques such as future potential exposure or valueat-risk measures. One advantage of keying reporting to the output of banks' own assessment

models is that it would yield the most accurate risk profile and keep up with the latest developments in risk-assessment techniques; as banks' models improved, disclosure would improve. However, comparing risk assessments among institutions might present problems,

especially if those assessments were drawn from banks' own internal risk-management models. Another issue is the potentially proprietary nature of such information: requiring banks

to disclose more of their assessments could place them at a competitive disadvantage.

Another issue is the usefulness and accuracy of the methods banks use to assess risk, which

might not be known until the measures were tested by an episode of financial turmoil. Some

research, for example, has called into question the performance of value-at-risk models. Such

measures are based on historical volatility and may underestimate the risk of so-called outlier

events, such as the Russian government's default, that are not likely to occur but nevertheless

sometimes happen. A case study by the Federal Reserve on improving bank disclosure says,

"In particular, there appears to be little connection between the degree of risk suggested by a

firm’s value-at-risk (VaR) disclosures and its actual trading account performance in the wake

of the financial shock in the third quarter of 1998."25

Improving Public Reporting

Expanding the scope of the data published in the Country Exposure Lending Survey and in

banks' annual reports might help improve public reporting on foreign exposure. As noted

earlier, the CELS currently provides aggregated exposure data for all banks with any foreign

exposure and for three smaller groups (money center banks, other large banks, and all other

banks). A simple improvement that would aid investors and policymakers in assessing foreign exposure would be to report those data bank by bank. 
32 U.S. BANKS’ EXPOSURE TO FOREIGN FINANCIAL LOSSES

The data now provided in annual reports and other filings required by the Securities and

Exchange Commission (SEC) could also be expanded. Currently, such reports provide limited information about the foreign exposure of bank holding companies. The SEC requires a

bank holding company to report, by country, the amount of its cross-border "outstandings"

but only for countries in which such exposure exceeds 1 percent of the company's total assets. However, that measure is limited in what it includes. For example, it does not include

total local country claims, which now make up a significant share of foreign exposure. The

SEC requires only that net local country claims—the extent to which local country claims

exceed local country liabilities—be included in reported foreign exposure. The uneven treatment of loans and deposits in Argentina in early 2002, as discussed earlier, is an example of a

case in which it may be more appropriate to include total local country claims in foreign

exposure rather than just net local country claims.

Separately reporting local country derivative exposure would also improve the information

that the CELS provides about banks' risks. Local country claims as a share of total foreign

exposure have been growing faster than have cross-border claims. But whether that increase

is due to lending exposure or derivative exposure—which, in any case, may move in different

directions in times of financial uncertainty—is unknown. Because the CELS does not break

out the two components in calculating total local country claims, changes in them may offset

each other and obscure potentially valuable information about exposure and risk. The speed

with which derivative exposure can change raises the deeper question of whether better measures of such exposure might be devised.
Appendix: Derivatives

and Their Markets

The expanding use of derivatives by banks and other investors has spurred the development of new forms and more complex transactions. As the range of derivative contracts has

grown, so have the markets in which they are traded. Today, much attention centers on the

market for over-the-counter derivatives—privately traded instruments that can be designed

to meet the needs of the parties involved.

Types of Derivatives

Options and forward contracts are the two basic types of derivatives. Options are the right

but not the obligation to buy or sell some underlying asset at a specified price (the strike

price) by a specified date (called the expiration date). Options with standard features, such as

an option for an exchange-traded stock with a set strike price and expiration date, can be

traded on an organized exchange or negotiated privately.

A forward contract is the obligation of one counterparty to buy and the other counterparty to

sell an underlying commodity or security at a specific price at a date in the future—in other

words, a bilateral agreement. Forward markets exist for many kinds of "underlyings," such as

commodities, currencies, and interest rates. The value of a forward contract may fluctuate

during the life of the contract, but no money changes hands until the maturity date (although collateral may be used to guarantee a party's performance).

A futures contract is a special type of forward contract. The purchaser (or seller) of a futures

contract is obligated to buy (or sell) a specific underlying at a specific price on the contract's

maturity date. However, unlike the operation of a forward contract, in which no money and

no underlying security or commodity changes hands until the maturity date, any changes in

the value of a futures contract are settled, or paid, daily on an organized exchange such as the

Chicago Board of Trade. To facilitate trading, certain features of futures contracts are standardized.

A swap is a forward-based derivative. Like a forward contract, it is a bilateral agreement,

tailored to meet the specific needs of the counterparties. A swap obligates a pair of counterparties to exchange a series of cash flows, based on a notional amount of principal, at specified intervals, or settlement dates. The cash flows exchanged in a swap are calculated by
34 U.S. BANKS’ EXPOSURE TO FOREIGN FINANCIAL LOSSES

multiplying the underlying notional principal by the interest rate, exchange rate, or price

specified in the contract. Thus, a swap is equivalent to a series of forward contracts. 

In a simple currency swap, principal and interest payments in one currency are swapped for

principal and interest payments in another. The principal amounts, which are set to be

equivalent using the exchange rates prevailing at the initiation of the swap agreement, are

usually exchanged at the beginning and at the end of the agreement's life. A currency swap

can effectively transform borrowing in one currency to borrowing in another. 

In an interest rate swap, interest payment streams of different types are exchanged. The three

main types of interest rate swaps are a coupon swap, which swaps the payment stream from a

fixed interest rate for the stream from a floating interest rate; a basis swap, which exchanges

one floating rate for another; and a cross-currency interest rate swap, which swaps a fixed

rate in one currency for a floating rate in another.

Markets for Derivatives

Some derivatives—for example, options and futures contracts—may be bought and sold on

organized exchanges, and some are privately negotiated in the so-called over-the-counter

(OTC) market. To be "exchange-traded," derivative contracts must be standardized with

regard to the amount of the underlying, the settlement or expiration date, and so forth. They

are then listed and traded on the exchange, and accounts are settled through a clearinghouse.

Legally, the clearinghouse is the counterparty for exchange-traded derivatives—that is, the

agent responsible for upholding the derivative contract. A benefit of that system is that transactions can occur in an active, liquid market. 

OTC derivatives, in contrast, are essentially bilateral contracts—privately negotiated transactions between counterparties. Nevertheless, many OTC derivatives are traded using standardized agreements, resulting in low transaction costs. Interest rate swaps, which have an

extremely active, liquid market, are an example of such derivatives. The main benefit of

OTC derivatives is that they can be tailored to the needs of the two parties; their major

drawback is that they pose a higher risk of default than do exchange-traded derivatives. Some

very specialized agreements may also be illiquid.

Why Markets for Derivatives Have Grown

The growth in financial derivatives has been fueled by both demand and supply factors.

First, on the demand side, sustained shifts (such as the advent of floating exchange rates in

1973) and surges in the volatility of markets led to increased demand for derivatives that

allow investors to separate and transfer market risk—that is, the possibility that the value of

assets or liabilities will change because of ups or downs in their prices. Market volatility, as

measured by the standard deviation of returns on Treasury bonds, rose from an average of

8 percent per year in the 1970s to 15 percent in the 1980s.1 Since the mid-1980s, several

temporary surges in market volatility have occurred, such as those in the summer of 1997

(associated with the Asian crisis) and the autumn of 1998 (accompanying Russia's default on

its debt). 

A second factor that led banks to increase their demand for derivatives was the considerable

competitive pressure from other financial institutions that they have faced over the past two

decades. On the deposit side, banks encountered more competition for household savings

from entities such as pension funds, insurance companies, and mutual funds, and that competition induced them to pay more competitive and more variable interest rates to attract

deposits. At the same time, competition on the lending side also intensified, as many of the

best borrowers turned to the securities markets to raise funds. With the cost of funds so

sensitive to the market, banks learned to separate funding risk from market risk by using

interest rate swaps and other derivatives. 

A third factor driving banks' demand for financial derivatives was the capital standards imposed by regulators. For example, under the Basle Accord of 1989 (a multilateral agreement

that established a uniform standard of capital adequacy to safeguard against financial risks),

an interbank swap required banks to hold only a small fraction of the capital required for an

equivalent interbank cash position on the balance sheet.2

Supply factors also contributed to the huge growth of derivative use since the mid-1980s.

Such factors include technological advances in telecommunications and computing power

and the development of option pricing and simulation models. In particular, the greatly

reduced costs and expanded scope of telecommunications helped create a global market by

allowing financial institutions to match up users of derivatives who were previously isolated

from each other.3
