Causes of the U.S. Dollar shortage During the Great Financial Crisis

Sources of funding in banks can become unstable, and the global financial crisis proved this. During the crisis, the majority of the banks had a hard time acquiring short-term U.S. dollar funding. Thus, this led to central banks across the world employing extreme policy approaches, such as international swap arrangements with the U.S. Federal Reserve. The reason was to be able to supply commercial banks with U.S. dollars per their jurisdictions.

The Bank of International Settlements (BIS) identified reasons for the U.S Dollar shortage during the Great Financial Crisis as follows:

Increased Appetite for Foreign Currency Assets

The investors had overwhelmingly high thirst for the so-called “safe haven” or foreign currency assets, notably the U.S. denominated claims on non-bank entities. The funding difficulty during the GFC had a direct relation to the considerable bank’s global balance sheets expansion over the past decade before the crisis. Thus, the growth of banks’ balance sheets respectively heightened their thirst for foreign currency assets.

Cross Currency Funding

This refers to the extent to which banks invest in one currency and fund in another via F.X. swaps. Europe and Japan banking systems mainly engaged in cross-currency funding. Since 2000, the two banking systems took enormous amounts of the net on-balance-sheet positions in foreign currencies, especially in U.S. dollars. The associated currencies exposures were left hedged off-balance-sheet since the accumulation of net foreign currency position led to a situation where the banks were on a foreign currency funding risk. In other words, these banks were exposed to the risk that their funding positions could not be rolled over.

U.S.Dollar Funding Gap

Unlike domestic banks, non-US banks had limited access to a stable base of dollar deposits. This means that they relied on short-term and potentially more volatile sources of funding, such as commercial paper and loans from other banks.A lower bound approximate of banks’ funding gap, which is the net amount of U.S. dollars channeled to non-banks, shows the vast funding needs of the major European banks’. It became more complicated to secure this funding became more difficult after the onset of the crisis. This is because, after the GFC, credit risk concerns led to disruptions in the interbank and F.X. swap markets as well as in money market funds. European banks reacted to these disruptions, through the support of central banks, up to 2008.

Reversal of Carry Trades

The dollar profited from the unwinding of carry trades. A carry trade involves an investor holding a high-yielding currency asset (target asset), which is financed with a low-yielding currency liability (funding liability).When financial markets become very volatile, the target currencies with the most lucrative yields significantly depreciate, and the funding currencies appreciate. This was the case during the GFC. The dollar interest rates decline by mid-2008 had already recommended the dollar to carry traders as a funding currency alongside the yen.

 When equity volatility rose, the higher currency’s yield in the previous six months implied a higher depreciation against the dollar. Target currencies were struck (hit hard) as investors sold them against the dollar or yen.

Over Hedging of Non-US Banks and Non-US Institutional Investors

Many banks invested heavily in the U.S. dollar assets in the years to mid-2007. They funded these positions by borrowing dollars directly from various counterparties, as well as using foreign exchange swaps.

Dollar asset declines left institutional investors outside the United States over hedged. Additionally, they squared their positions, leading to a boost of the dollar. European banks were forced to buy dollars in the spot market as they wrote down the value of holdings of dollar securities. The aim was to retire the corresponding hedges. On the same note, European pension funds bought the dollar as they experienced losses on dollar securities hedged into the euro.

Importance of Assessing Maturity/Currency Mismatch Across the Balance Sheets of Consolidated Entities

Banks’ International Positions: Concepts and Data

Much stress accumulates ina global balance sheet. They come in the form of assets and liabilities maturity or currency mismatches, and comprehending them can only be achieved by looking into banks’ worldwide positions consolidated across all office locations.For a bank aiming to expand globally, it needs to fund a specific portfolio of securities and loans in which some of it is based on foreign currencies.

Banks can finance these foreign currency positions through:

  1. Borrowing of domestic currency then converting through straight F.X. spot transaction, hence being able to buy the foreign asset in the converted currency.
  2. Converting domestic currency liabilities into foreign currency through the use of F.X. swaps and purchasing foreign assets.
  3. Borrowing foreign currency through the interbank market, mainly from central banks or participants of the non-bank market.

Banks get vulnerable to funding risks as a result of the different options of funding or in situations where they are unable to roll over funding liabilities. The degree of maturity transformation associated with a bank balance sheet is what determines the implications of the risk. The need to invest relies on the preferred holding period, market liquidity, and the underlying asset’s maturity. In case the rolling over of the contractual liabilities is not possible, the foreign currency assets meant for holding are rather sold and more likely in conditions of distressed market situations. A funding gap refers to the amount that banks must rollover before the maturity of their investments

Funding Risk

Technically, funding risk is associated with stresses on a broad basis in the global balance sheet: the mismatches between currency, maturity, and counterparty of liabilities and assets. In quantifying these threats, there is a need to measure banking activities based on consolidation, specifically at individual banks (decision making economic unit) level. Data on a clear breakdown of positions per currency, liabilities, and assets, counterparty and maturity type, as well as off-balance sheet positions, are meant to assist in susceptibility identification. However, public information available fails to factor in this idea. Although published bank accounts on a consolidated level are available, they lack essential information on the breakdown of maturity, counterparty, and currency required.

Construction of Individual Bank’s Global Balance Sheet

The structure of the individual bank’s global balance sheet entails summing up the local and cross-border balance sheet positions from its domestic offices and the host states around the globe into a consolidated whole for each banking system.

Long and Short of the Banks’ Global Balance Sheets

The Structure of Banks’ Operations

Banks that are actively operating across the world have numerous offices in various countries. Their management of maturity and currencies are based on a consolidated global entity instead of per office.This implies that significant mismatches measured on an office’s balanced sheet located in a different office may be offset/hedged off-balance sheet through an on-balance sheet position booked by other offices elsewhere. This results in a matched book for the bank as a whole.

Balance Sheet Expansion since 2000

The banks’ international balance sheet expansions since 2000 are highly associated with the U.S. dollar shortage. The stock on banks’ foreign claims significantly grew from $10 trillion at the start of 2000 to $34 trillion by the end of 2007. By 2001, international claims were at 10% while at the end of 2007, it approached 30%. These significant improvements occurred mainly during the financial innovation period. It included expansion growth in the hedge fund industry, the introduction of financial structures, and the spreading of universal banking, which combined proprietary trading, investment, and commercial banking activities.

In 1999, there was the introduction of a single currency, leading to an increase in some European banking systems, and the outcome was significant intra-euro area lending. Their approximated positions dominated by the U.S. dollar and other non-euro is mainly responsible for most of the overall expansion in their foreign assets between the end of 2000 and the mid of 2007.

Maturity Transformation across Banks’ Balance Sheets

In banking, maturity transformation plays a critical role. Necessarily, banks are required to make the transfer of funds from agents in excess, demanding short-term deposits to agents in deficit with long-term financing needs. The maturity mismatch needed for the facilitation of long-term investment projects, as well as serving the liquidity needs of the investor, should allow banks to earn a spread in a positive slope surrounding.

Banks might get motivated to excessively increase their maturity mismatch, thus rendering themselves vulnerable to the funding risks embedded in the need for rolling-over short-term liabilities. Excessive maturity transformation creates undesirable financial stability issues as it puts the entire banking system at risk.

How Central Bank Swap Agreements Overcome Challenges Commonly Associated with International Lenders of Last Resort

The U.S. Dollar Shortage

A dollar shortage refers to a scenario where a country lacks a sufficient supply of the U.S. dollar for effective management of international trade. This situation comes into place when a country is required to pay more U.S. dollars for its imports as compared to the U.S. dollars received from exports.

Most countries have to hold their assets in dollars to sustain the steady growth of the economy and transact with other countries who use the U.S. dollar since it is the globe’s key traded currency.

When a dollar shortage occurs, it affects the global trade since the U.S. dollar acts as a peg for other currencies’ value. The dollar serves as a reserve currency controlled by the central banks in which it purposes to maintain stability reputation, thus, essentially making the U.S. dollar utilized in assets pricing.

During the GFC, maturity transformation was unsustainable since the leading banks’ sources of short-term funding were unstable contrary to their expectation. Short-term interbank funding got compromised by increased counterparty liquidity and risk. The associated disarrangements in F.X. swap markets made it even worse, as it was expensive to acquire U.S. dollars through currency swaps. On the other hand, the European bank’s U.S. dollar funding needs were more than other entities’ funding requirements in different currencies.

The International Policy Response

International policy response came into place due to the severe U.S. dollar shortage among banks outside the United States. The Central bank of Europe embraced measures to relieve funding pressures in their domestic currencies since they were unable to avail of adequate U.S. dollar liquidity. They thus opted for temporary reciprocal currency arrangements (swap lines with the Federal Reserve) to have U.S. dollars directed to banks with their corresponding jurisdictions.

Through providing the U.S. dollars on a worldwide scale, the Federal Reserve technically participated in international lending of last resort.

The Success of the International Policy Response

  • The Auctioning of the U.S. dollar led to a minimized level of volatile swap spread.
  • It assisted in averting more large-scale distress-selling of assets with dollar denomination.
  • It mitigated upward pressure and interbank rate volatility on the U.S. dollar.

The international swap arrangements mitigate two main challenges, mainly related to international lending of last resort. These include:

  • The Federal Reserve and its foreign counterparts are accorded the power of creating whatever amounts of money they choose to as compared to global financial institutions administering resources in limited nature.
  • The Swap network does not consist of information issues that can lead to moral dangers.
