A Currency Board as an Alternative to a Central Bank
Summary
The Foreign Operations Act (P.L. 102-391) signed on October 6, 1992 allows
the U.S. quota, or contribution, increase to the IMF of $12 billion to be used to
“...support monetary stability in member countries through the instrumentality of
currency boards.” What is a currency board? How does it differ from an alternative
monetary arrangement such as a central bank? Why was it adopted by countries with
histories of chronic inflation (e.g., Argentina) and those emerging from the Soviet
bloc (e.g., Bulgaria), and urged upon those suddenly hit by currency speculation (e.g.,
Indonesia)? What role did the currency board play in Argentina’s 2001-2003
financial difficulties and why was it abandoned? Although factors affecting the
decision to adopt a currency board vary from country to country, as do outcomes,
fundamental differences between currency boards and central banks remain constant.
This report focuses on their differences to provide a foundation for evaluating
disparate cases.
To understand the differences, it should be noted that the most important
function of a central bank is its ability to alter the supply of money. When this power
is abused, as occurs when central banks must provide the monetary wherewithal to
finance government budget deficits, it undermines the functions that money performs
in a market economy: that of a unit of account, medium of exchange, and store of
value. History is replete with episodes of such an abuse of monetary policy. The
most egregious consequences of abuse are to be found in episodes of hyperinflation
with prices rising daily. Countries have sought a variety of monetary arrangements
to curtail abuse in the issuance of money.
A significant example is a currency board. Currency boards now function in
Bulgaria, Hong Kong, Djibouti, Lithuania, Estonia, and Brunei, and are promoted by
some economists as a means for developing countries to achieve macroeconomic
stability. The sole function of these boards is to issue currency (and coins) that are
100% backed by a commodity (e.g., gold and silver) or by the stable valued currency
of another country. A currency board is forbidden from altering the amount of
currency by buying or selling assets denominated in domestic money. As a result, the
currency it issues is "safe" or of stable value (or as stable in value as the currency to
which it is linked), and this stability would contribute to the vital role money plays
in market economies. A currency board arrangement is very similar in nature to the
formal adoption of another country’s currency, popularly known as “dollarization.”
Using a currency board has a potential downside for a country. It is exposed to
every shock that affects the exchange rate of the country to which it has tied its
currency, and prevents the use of monetary policy to counter those shocks. Argentina
is a recent example of what can happen in a currency board country. Argentina
linked its currency to the U.S. dollar. The large appreciation of the dollar between
mid-1995 and 2002 had a severely depressing affect on the Argentine economy
which led to the abandonment of the currency board and economic crisis. Unlike
central banks, currency boards also lack a lender-of-last-resort function. In a
financial crisis, currency boards would be unable to lower interest rates and lend
banks money to quell bank runs. This report will not be updated.

A Currency Board as an Alternative to A
Central Bank
A major institution in most modern market economies is a central bank. The
Federal Reserve System of the United States is an example. It has a variety of
powers and functions to perform. Important among these is the ability to alter the
reserve and lending base of commercial banks (and in the process, the supply of
money), to act as the lender of last resort to the financial system, to provide facilities
for clearing checks, to serve as fiscal adviser to the federal government, and to
provide economic advice.
Suppose that the Federal Reserve were suddenly shorn of all its powers and,
instead, its sole function was to issue currency and coins that were secured or backed
100% by gold, silver or other commodities or by the currency of another country,
such as Switzerland or Germany whose inflation rate had been low for a considerable
period of time. Further, suppose that the exchange rate of the dollar in terms of the
commodity or foreign currency would be fixed immutably and could only be changed
under circumstances that were well defined in the law. Moreover, to ensure that the
new system worked as intended, a majority of the governors of the "reformed"
Federal Reserve would be foreigners, the institutional headquarters and the site where
the reserves of the system were deposited would be in some foreign "safe haven," and
these reserves would be inaccessible to the government of the United States.
Many informed Americans would, no doubt, consider this a radical change in
the conduct of U.S. monetary policy. Yet, this type of monetary regime, which is
called a "currency board," is currently in use in the manner described in this paper in
Bulgaria, Hong Kong, Djibouti, Lithuania, Estonia and Brunei.1 It played an
important role in Argentina between 1991 and 2002 .
An important role of Congress is to work with the Administration, the Federal
Reserve, and international institutions such as the International Monetary Fund to
build a stable and prosperous world economy. A prosperous world economy is
beneficial to the American economy, through a robust international trade sector, and
it is thought to bring political benefits as well, through its perceived salutary effect

independent, many decided to replace their currency boards with central banks. For a
discussion of this experience, see H.A. Shannon, “Evolution of the Colonial Sterling
Exchange Standard,” International Monetary Fund Staff Papers, April 1961, pp. 334-354;

on the political stability of our allies. Sustainable exchange rate regimes are a key
element of a stable macroeconomic framework, and a stable macroeconomic
framework is a prerequisite to a country’s development prospects. These conditions
have been recognized by Congress. To that end, Congress recommended in P.L.102-
391, signed October 6, 1992 to take effect in FY1993, that the IMF quota increase
be used to “...support monetary stability in member countries through the
instrumentality of currency boards.”
Proponents claim that a currency board can offer a stable exchange rate and
monetary regime to a developing country with a history of macroeconomic
instability. It was introduced in Argentina as an intended cure for that country’s
problems with high inflation and in Bulgaria, Estonia, and Lithuania to aid them in
their transition to a market economy. During the Asian crisis, proponents urged its
adoption in Indonesia to help stabilize its depreciating currency. Opponents claim
that a currency board has the potential to further destabilize countries already
hampered by past mistakes. Opponents claim that the presence of a currency board
was central to Argentina’s 1999-2002 problems.2 This report will describe a
currency board monetary regime, how it functions, how it compares with a central
bank system, and discuss assessments of its strengths and limitations.
The Currency Board System
In this type of monetary regime, an institution is created known as a currency
board3 whose only function is to issue and exchange local currency and coin on
demand at a fixed rate of exchange for a given quantity of a commodity or for a
foreign currency (known, respectively, as the reserve asset and reserve currency, and
the country whose assets back the currency board is known as the reserve country).
In Argentina, for example, the currency board could only issue the local currency,
called the peso, upon the receipt of U.S. dollars. Likewise, it would exchange dollars
for pesos on a one-for-one basis. As a result, the notes and coins issued by currency
boards are secured 100% by a commodity or a foreign currency (in the case of
Argentina, by the U.S. dollar).
In actual practice, a currency board would not hold all its assets in the foreign
currency. Rather, some of its assets, perhaps a large proportion, would be held in an

interest-earning form denominated in the reserve currency (e.g., U.S. Treasury bond).
This helps ensure that the board earns sufficient income to offset the expenses of
maintaining its currency and coins in circulation as well as build up a reserve to cover
any possible losses that might be sustained because of adverse movements in the
interest rates on the securities it holds, or due to defaults.
It is important to note that a currency board would be prohibited from
purchasing any assets, financial or otherwise, denominated in local currency. If it
were not so prohibited, it could function exactly as a central bank and be able to
independently alter the money supply and short-term interest rates through so-called
"open market operations."4 Thus, the use of a major policy tool in traditional
monetary policy involving variations in the supply of money through open market
operations is ruled out. The inability to engage in a discretionary monetary policy is
likely to be a major reason why currency boards remain an unattractive alternative
for many countries.
Nothing in a currency board regime would prohibit commercial banks in that
country from existing and issuing demand, saving, and time deposits as well as
money market accounts. Thus, the existence of a currency board does not rule out
the development of a range of liquid financial assets or the development of
commercial banking or the financial system in general. The deposits of commercial
banks, however, would not be backed 100% by reserve currency. The type of
fractional reserve banking typical of the United States and other developed countries
could be a feature of a currency board regime.5 Hypothetically, unless explicitly
prohibited, variations in the reserve ratio by some central authority would make
possible some variations in the money supply relative to the base of reserve currency
or amount of local currency outstanding.
The assorted non-monetary functions often performed by central banks would
have to be assumed by some other government agency. These include serving as a
depository for bank reserves, acting as a lender of last resort to the banking system,
managing foreign exchange reserves, operating a clearing house, serving as a fiscal
agent for the government, administering a deposit insurance system, regulating
financial institutions, and offering economic advice to the government.
4 Open market operations involve the purchase of government securities or other qualified
assets such as commercial paper or foreign exchange by the central bank. When these assets
are purchased, the effect on the economy is the same as if new currency were created.
Economists say that these open market operations create "high powered money" since this
money can serve as the reserves of the banking system and be used to create multiple dollars
of deposit money.
5 Banks in the United States are legally obligated to hold a sum equal to 10% of their
demand deposits above $42.8 million (3% below $42.8 million) in the form of currency, in
their own vaults, or on deposit with the Federal Reserve. Against all other deposits, banks
hold reserves which prudence suggests are adequate to meet sudden withdrawals. In the
currency board system, these reserves would take the form of local currency and would be
held either as vault cash or on deposit with a government agency other than the currency
board. The latter would not be a depository for bank reserves.

CRS-4
Countries that have currency boards are not precluded from participating in
international trade and are likely to be both international lenders and the recipient of
international capital flows. Their participation in the world of international trade and
finance is, however, somewhat indirect. The exchange rate between their currency
and the currency of the reserve country is fixed. Even though the two currencies may
look different, reflecting preferences in national design, they are exchangeable at a
fixed rate. Since they are fixed, the currency board country’s exchange rate with the
rest of the world is automatically determined by the reserve country’s exchange rate
with the rest of the world. Thus, if Estonia, a currency board country, links its
currency to the euro, and the euro appreciates in foreign exchange markets by, say,
25%, the Estonian currency would also appreciate by the same amount. This means
that any change in the exchange rate of the reserve country relative to that of any
other country will also be experienced by the currency board country. As explained
below, this can be a disadvantage of a currency board. If the currency of the reserve
country appreciates on world financial markets, it could force a deflation on the
currency board country.
Money Supply Growth
While excessive money supply growth is the source of excessive inflation, some
money growth is necessary for a stable price level. Price level stability requires that
the growth in money spending match the growth in potential output. And the growth
in money spending is likely to require some growth in the supply of money. In a
currency board regime, money supply growth can come about from either the growth
in currency or the growth in those bank deposits counted as money (e.g., deposits on
which checks can be drawn).
For currency to grow, the currency board must acquire additional reserve
currency or reserve assets and this happens primarily through the balance of
international payments. The currency board country must receive in payment more
than is paid out for the trade of goods and services; receipts from gifts, unilateral
transfers, and other income; and from the sale of capital assets (i.e., an inflow of
foreign investment).6 This net difference is then settled by an inflow of monies that
can be converted into reserve currency. The growth in reserve currency will then
permit an increase in the local currency issued by the currency board.
The money supply itself can continue to increase even if the stock of currency
remains constant. This can and does occur when individuals desire to hold less of
their liquid wealth in the form of currency. The redundant currency is then deposited
in banks where it serves as reserves for a multiple increase in the amount of deposit
money. In addition, as noted above, some central authority could alter the legal
reserve requirement imposed on bank deposits, allowing some additional flexibility
in the supply of money. There are, of course, limits to the range of variation in
reserve requirements.
6 There is one other way for the supply of currency to grow. This is from the income earned
on the reserve assets held by the currency board. These earnings, however, will be recorded
in the country’s international balance of payments.

CRS-5
The question arises whether a currency board regime can provide for a rate of
growth of the money supply and money spending over time that will yield a stable
price level. The answer to the question is that in a currency board system, money
supply growth comes to depend heavily on the monetary policy pursued by the
country whose currency is used as a reserve. As long as inflation in the reserve
country is stable, the currency board will automatically cause a similar (but not
identical) inflation rate in the currency board country. Thus, if money supply growth
in the currency board country is too rapid, so that inflation occurs, individuals would
shift to buying goods in other countries and people in other countries would refrain
from buying the now more expensive goods produced in the currency board country.
This would produce a trade deficit (or smaller surplus), all else equal. This deficit
would drain currency reserves from the currency board and bring about an automatic
contraction of the money supply and, with it, a fall in the inflation rate.
Alternatively, should the money supply and money spending grow more slowly
in the currency board country than in the reserve currency country, its lower rate of
inflation would lead to increased exports to the reserve currency country. This would
lead to a balance of payments surplus, an inflow of reserve currency, a deposit of
some of this currency in banks (which would augment their reserves), and a multiple
expansion of the money supply and a more rapid rate of growth of money spending.7
It is not an uncommon event for economies to experience sudden and dramatic
changes in the public's willingness to hold bank deposits. A monetary system should
be able to accommodate shifts in the composition of money balances between
currency and deposits in a way that does not alter the size of the money stock. A
currency board regime may be ill-suited to deal with such changes. Should such a
sudden desire for currency manifest itself in a currency board system, there is no
mechanism by which currency can be supplied to accommodate the sudden surge in
7 There is a popular alternative theoretical explanation for the behavior of the balance of
payments, the so-called Monetary Approach. It suggests a somewhat different chain of
events if the currency board country's money supply growth is insufficient to accommodate
the growth in money demand following a growth in real income. According to this
approach, the growth in real output would increase the demand for money. If the domestic
money supply did not expand to accommodate this demand, actual money holding would
then be less than desired holdings. In order to build up money balances, individuals would
be led to refrain from spending. Some of the decreased spending would fall on imported
goods tending to produce a balance of payments surplus, an inflow of reservable currency
and an expansion in the money supply (some of the reservable currency would become
additional bank reserves on the basis of which additional deposit money could be created).
This analysis would also be relevant to a situation in which a reservable asset such as gold
is used in place of a reservable currency. If this theory is correct, it suggests that from time
to time the economy would be placed under deflationary pressure as individuals attempted
to build up their money balances. Similarly, the economy would come under inflationary
pressure if the domestic money supply grew too rapidly. For a discussion of this approach,
see Mordechai E. Kreinin and Lawrence H. Officer, The Monetary Approach to the Balance
of Payments: A Survey, Princeton Studies in International Finance. No. 43, (Princeton:
1978).

demand.8 Instead, the money supply must shrink, causing price deflation. This
phenomenon is what economists have in mind when they say that currency board
countries do not have a lender of last resort. In this instance, it is the absence of a
central authority for supplying the additional currency demanded by the public.
Similarities to Dollarization
A currency board is a monetary arrangement that most closely resembles the
unilateral adoption by a country of a foreign currency, popularly known as
“dollarization.” Some countries do not issue their own local currency, but instead
use foreign currencies for their domestic transactions. For example, Ecuador and
Panama use the U.S. dollar. In these countries, the money supply grows when
citizens receive more dollars through international trade and investment and
unilateral transfers then they send abroad for these purposes. These same factors
cause the money supply to increase under a currency board. In a dollarized country,
local credit conditions are altered anytime the Federal Reserve alters monetary policy,
just as in a country with a currency board tied to the dollar.
The only economic difference between the two is that a currency board is a way
for a country to both have the benefits that come from a link to a large stable valued
currency and, at the same time, earn the income called seigniorage that comes from
issuing its own money. By contrast, the seigniorage of dollarized countries is
collected by the U.S. government. This profit can be viewed in two ways. First, each
dollar the U.S. government issues enables it to buy a dollar’s worth of goods and
services. Since it uses up some resources to print and maintain the dollar in
circulation, the net amount of goods and services it can buy is somewhat less than a
dollar. Second, issuing currency to buy goods and services can be thought of as an
alternative to issuing interest-bearing debt for the same purposes. Hence, each dollar
of currency issued means that the U.S. government saves the interest it would have
to pay if it had instead issued interest-bearing debt. The amount of interest saved is
not a one-time event. It is saved year after year. The present discounted value of
those interest payments is equal to the amount of currency issued (less the cost to
maintain that currency in circulation). By using another country’s currency, a
government gives up seigniorage.
A currency board enables a government to capture seigniorage. This occurs
because the reservable assets held by the currency board as backing for the notes and
coins that it issues would not likely be held entirely in foreign currency or metals.
Rather, some part, potentially a large part, would be held in highly liquid interest
earning assets (denominated in the reserve currency). The income earned on these
assets over and above that required to defray the costs of operating the system would
be available to the government. Thus, a currency board regime can generate
seigniorage, but perhaps somewhat less than would be available under a comparable
central banking regime.
8 The ratio of currency to deposits has undergone many and sometimes rapid changes in the
United States. For an examination of the behavior of the currency ratios during the period
1920-1980, see Mark Ladenson and Gail Makinen, “The Currency Ratios 1920-1980: A Re-
examination,” Atlantic Economic Journal, Dec. 1992.

CRS-7
Historically, many countries chose currency boards because they were very
small and found a central bank an expensive institution to operate. This helps
explain why currency boards were used extensively by many British colonial
dependencies, some of which were small island states or sparsely populated areas.
These colonial dependencies chose to operate a currency board instead of simply
adopting the British pound because of the desire for seigniorage earnings.
Comparison with a Central Bank
To further highlight the characteristics of a currency board regime, it is useful
to compare it to a central bank regime. To make a valid comparison, it must be with
a central bank operating in a system of fixed exchange rates.9 Such a monetary
regime is compatible with both the gold standard and the so-called Bretton Woods
system that evolved after World War II and remained a fixture of the world economy
until the early 1970s.10 Since the collapse of the Bretton Woods system, many
developing countries have operated fixed exchange rate systems and some European
countries participated in a fixed exchange rate system called the European Monetary
System before the creation of the euro.
A fixed exchange rate regime imposes substantial limitations on the conduct of
monetary policy by a central bank. Essentially, monetary policy is constrained by the
necessity to maintain the fixed exchange rate. It would be difficult, for example, in
such a regime to focus monetary policy on a goal designed to maintain high
employment. To the extent that this requires interest rates below comparable rates
elsewhere, it encourages the outflow of capital, a balance of payments deficit, and the
loss of international reserves (either of gold or foreign exchange) as the central bank
seeks to prevent the exchange rate from depreciating. The end result of policies that
conflict with the need to maintain the exchange rate is a change in the balance sheet
of the central bank: reserves of gold and foreign exchange are lost and replaced by
government bonds or other domestic assets that are eligible for open market
operations. Moreover, the pursuit of goals that conflict with the need to maintain the
exchange rate are viable only in the very short run since, ultimately, the central bank
would run out of reserves needed to support the exchange rate.
In a fixed exchange rate system, a central bank intent on maintaining the
exchange rate is little different in its behavior from a currency board: It must stand
ready to convert its money into gold or other foreign currencies on demand at the
fixed rate of exchange. Moreover, as in a currency board regime, the monetary
system in a central bank regime is unlikely to have its outstanding money supply
backed 100% by gold and foreign exchange. But unlike a currency board, a
9 The power of a central bank and monetary policy is greatly enhanced in a world that uses
flexible exchange rates. However, since a currency board system is one of fixed exchange
rates, it would be misleading to compare it to a central bank operating in a flexible exchange
rate world.
10 The U.S. occupied a special place in the Bretton Woods system in that it supplied the
reserve currency. Thus, the U.S. central bank did not face many of the constraints faced by
other central banks. The comparison in this section is a comparison with a non-reserve
currency central bank.

substantial portion of the money stock would be "backed" by central bank and
commercial bank holdings of assets denominated in domestic money. This allows
the central bank to alter the money supply in the pursuit of domestic goals such as
full employment, as long as this goal does not contradict the maintenance of the fixed
exchange rate to the extent that it triggers large capital outflows.
The proponents of currency boards stress a crucial difference between the two
systems: central banks maintain pegged, not fixed exchange rates whereas currency
boards maintain fixed exchange rates. This means that the exchange rates in a so-
called fixed-rate central banking system are often subject to unexpected changes.
History demonstrates that when fixed exchange rate regimes prevailed, there were
frequent changes in the exchange rates, often because the central banks were used to
promote goals such as high employment that were incompatible with the exchange
rate. When the rates were changed, it was often in response to massive speculative
attacks on the currency in question. The attacks on the British pound and Italian lira
that occurred in September 1992 and the East Asian currencies (Phillippines,
Indonesia, Thailand, and Hong Kong) in 1997 are typical of the circumstances under
which pegged exchange rates are changed.
Currency boards, on the other hand, automatically defend the exchange rate
because they cannot pursue any other economic goal than currency convertibility and
cannot hold reserves denominated in local currency. However, opponents of
currency boards would argue that the viability of maintaining them when the
exchange rate has become unsustainable ultimately comes down to the willingness
of the government to accept deflation and recession, regardless of the fact that
combating these phenomena are not stated goals of monetary policy.11 When the
exchange rate becomes misaligned, the currency board must be abandoned unless the
government is willing to accept the deflation and accompanying recession necessary
for the exchange rate to become competitive again – just as is true in a fixed
exchange rate regime. Speculators moved against both the Argentine and Hong
Kong currency board in recent years because they doubted that the government would
accept deflation. In the case of Argentina they were right; not so with Hong Kong.
The Advantages and Disadvantages of Currency
Boards
Advantages
There are both political and economic reasons why countries find currency
boards an attractive alternative to central banks.
Currency Boards Eliminates High Inflation. Politically, while it is
common to think of a currency board as constraining a nation’s monetary policy, it
also exercises a considerable restraint on the fiscal activities of a government. Since
11 The currency board country would also have to be willing to accept inflation when the
money supply grew too rapidly, but the inflation rate would be far lower than what most
countries have historically experienced prior to the adoption of their currency boards.

CRS-9
local currency can be issued only in exchange for the reserve asset or currency, it
cannot be issued to purchase government debt and, hence, a government could no
longer finance budget deficits by recourse to the printing press as it could under some
central bank arrangements.12 Thus, countries that have a long history of inflation
linked to the financing of fiscal deficits by resort to the printing press or who place
a large premium on relatively stable prices are likely to find a currency board regime
an attractive alternative to a central bank. Argentina adopted a currency board after
a very troubled history of high and unstable inflation rates. The adoption of currency
boards by Estonia, Lithuania, and Bulgaria was motivated by a belief that this action
would ensure a stable valued currency and would facilitate their transition to market
economies and serve to entice foreign investment.
When monetary systems function smoothly, the important role that stable money
plays in market economies is frequently overlooked or neglected. Money performs
three important functions. First, it facilitates exchanges and reduces the time and
trouble inherent in barter. As a result it enables economies to produce and exchange
more goods and services than would be possible in a system that relied on barter.
Second, money as a common denominator in terms of which all goods and services
can be expressed makes possible modern accounting systems and the entire system
of contracts that are a cornerstone of business. Third, money is said to be a “store of
value,” which means that generalized purchasing power or wealth, either in the form
of money itself or financial instruments denominated in the unit of account, are made
possible in societies which have money. And these financial instruments play a
major role in the functioning of market economies.
When monetary systems do not function well, meaning those that experience
episodes of high inflation, the established money loses these qualities. With this
development, exchange is likely to revert to barter or involve the use foreign
currency, prices are quoted in a variety of different foreign monies, individuals are
no longer content to hold financial assets denominated in local currency, resources
are wasted avoiding inflation and repricing goods, and contracts disappear or become
very short term. Furthermore, production is hampered by low levels of foreign
investment and a lack of credit, as financial institutions tend to suspend operation or
fail to lend except for very short periods of time, and unemployment rises. In
general, a poorly functioning monetary system can be a severe handicap to an
economy. Because of this, some countries have opted for a currency board in the
belief that it will produce for them a stable currency and a stable monetary system.

12 The ability of a central bank to print money to finance a budget deficit depends on the
type of international monetary regime to which it is committed. A gold standard, for
example, requires that central bank monetary policy be geared to maintaining a given price
for gold. Similarly, a non-gold standard fixed exchange rate regime requires that the
monetary policy of a central bank must be governed by a commitment to maintain the
exchange rate within prescribed limits. Both types of regimes substantially limit the ability
of a central bank to provide financial support to the government. Any support that it gives
must be compatible with the objective to either keep the price of gold constant or the
exchange rate within prescribed limits. In a flexible exchange rate regime, these constraints
are removed (as they are in a fixed exchange rate regime if the government is not really
committed to maintaining the exchange rate).

Note: The third year represents the year of currency board adoption.
Currency Boards Prevent “Time-Inconsistency”. A second political
advantage to currency boards is that they are likely to be a good way to deal with
what economists call the “time inconsistency” problem. The ultimate purpose of
economic activity in market economies is the well-being of the consumer. That well-
being consists of being able to consume goods and services that come closest to
satisfying wants, to arrange work and leisure that conforms to individual preferences,
to enable consumers to divide their income between consumption and saving in such
a way that it maximizes their preferences between immediate and future gratification.
Economic activity also requires judicious decisions about choices for investing
saving among alternative investment possibilities, and so on. All of this activity
requires information. An important part of this information concerns the likely
policies of the government, especially the monetary policy of the central bank. On
the basis of expectations about these policies, individuals make choices and conclude
agreements or make contracts.
A “time consistent” policy regime is one in which the government carries out
the polices that it announces. In this case, individual expectations are fulfilled and
the choices they have made lead to an optimum outcome for them and for the
economy. However, there is an incentive for the government to “cheat,” or to carry
out policies that are different from those expected to prevail by economic agents.
Suppose, for example, that a central bank had as its announced goal a stable price
level and that economic agents believed that it would carry out policies to achieve
this end. These agents would then make contracts, for example, to fix money wages
based on the expectation that prices would be stable. If a central bank should
suddenly depart from this policy and, instead, engineer inflation, this would reduce
the real wage of labor and encourage businesses to hire more workers or work the
existing employees extra hours. This policy might generate a more rapid rate of GDP
growth and a lower unemployment rate, at least temporarily until it came time to
renegotiate various contacts. This change in central bank behavior would not,
however, be optimum from the perspective of economic agents. It is inconsistent
with the optimizing behavior of economic agents and from that perspective it is sub-
optimal. Had these agents known what was going to happen, they would have built
this into their expectations and their behavior. The central bank would have “fooled”

CRS-11
people once, but it is unlikely they would be able to fool them again. By losing
credibility, the central bank’s future policy would then be less effective. Perhaps it
is not surprising that countries who have adopted currency boards are often those in
which monetary policy has lost its credibility.13
A currency board is less likely to engage in time-inconsistent behavior because
it cannot engage in discretionary changes in the money supply and, thus, cannot
engineer monetary surprises because it is bound by a rule to increase currency only
to the extent that it acquires reservable assets. It has no discretion in altering the
amount of currency in circulation. This is not the case with a central bank, especially
one that operates in a country linked to other countries by flexible exchange rates.
Thus, it can be argued that a currency board regime is more likely to ensure time
consistent policies than would a central bank regime.
Currency Boards Encourage Trade and Investment. The major
economic advantage that a currency board has over floating exchange rates is that
exchange rate stability encourages international trade and investment. It does so by
eliminating the exchange rate risk involved in these transactions under floating
exchange rates. Since many economists believe that international trade and
investment are an important source of growth for developing countries, it is argued
that a currency board could have a significant effect on the sustainable rate of
economic growth. Traditional fixed exchange rate regimes also eliminate exchange
rate risk, but to the extent that currency boards are viewed as more durable than fixed
exchange rate regimes, currency boards do more to encourage international trade and
investment. Currency board proponents tend to argue that the extensive list of fixed
exchange rate failures in the 1990s have led investors to believe that currency boards
are the only fixed exchange rate regime that can be trusted. Hence, they claim, only
currency boards significantly increase international trade and investment.
Disadvantages
Currency boards also have their critics. The critics tend to concentrate their
attack along several lines.
Central Banks Can Act Responsibly. First, they point out that there is a
long history of responsible behavior by central banks. The central banks in many
countries have had great success in producing long periods of price stability and high
employment. The degree to which they are able to achieve this goal depends on
several factors. Important among them are an absence of negative supply side
shocks, such as those that arise from disruption in the world’s output of oil, and a
responsible fiscal policy on the part of government. Recent studies suggest that the
ability of central banks to pursue a goal of price stability depends critically on
government fiscal policy. Where fiscal deficits are large, even in the best of times,
where domestic capital markets are poorly developed, and where access to
13 See Finn Kydland and Edward Prescott, “Rules Rather than Discretion: The Inconsistency
of Optimal Plans,” Journal of Political Economy, v. 85, 1977, p. 473; and Robert Barro and
David Gordon, “Rules, Discretion, and Reputation in a Model of Monetary Policy,” Journal
of Monetary Economics, vol. 12, 1983, p. 101.

CRS-12
international credit is limited, central banks are often forced to print money to cover
fiscal shortfalls. Countries in these circumstances are prone to a poor inflation
performance. This is not the fault of central bank regimes per se. Rather, the fault
lies in a political process.14 Basically, critics of currency boards argue that floating
exchange rates offer valuable benefits and policymakers should focus on ways to
convince governments to act responsibly enough to enjoy them.15
The critics also question whether currency boards really solve the “time
inconsistency” problem. While it is true that a currency board itself cannot bring
about discretionary changes in the supply of currency (and money), they are exposed
to the “time inconsistency” tendencies of the reservable asset countries. Thus, for
example, if the U.S. Federal Reserve were to engage in “time inconsistent” behavior,
it would be communicated to a country such as Argentina regardless of the fact that
Argentina has a currency board.
Currency Boards Make a Country Vulnerable to Economic Shocks.
Another and more forceful line of criticism is that countries are often faced by a
variety of shocks that are most appropriately dealt with by adjusting exchange rates.
Since this is virtually impossible in a currency board regime, these shocks must be
dealt with either by deflation or inflation. Most worrisome are the deflationary
adjustments. The economic travails of Argentina, which abandoned its currency
board, have been used by critics to demonstrate problems posed by deflation in such
a monetary regime.16
14 It is useful to note that economists have devised a wide range of monetary rules
compatible with floating exchange rates that “tie the hands” of irresponsible policymakers.
For examples, see U.S. Library of Congress, Congressional Research Service, Formulation
of Monetary Policy by the Federal Reserve: Rules vs. Discretion, by (name redacted), CRS
Report RL31056 and The Federal Reserve: Should Its Sole Mandated Goal Be Price
Stability? by (name redacted) and Gail Makinen, CRS Report 98-16E.
15 By contrast, proponents argue governments will never act responsibly enough to enjoy the
benefits, making currency boards a “second best” solution.
16 This critique draws heavily from a small but important literature in monetary economics
known as the theory of “optimum currency areas.” When a currency board is created, it
automatically ties a local economy to the economy of the reserve currency country through
a fixed exchange rate between the two currencies. A question arises whether the new larger
currency area is an “optimum” arrangement. If the two regions’ business cycles are well
harmonized, then the arrangement is optimum. Business cycles tend not to be well
optimized if an economic shock does not affect the two regions’ economies equally. Even
if the two regions do not have well harmonized business cycles, a joint currency may still
succeed. The attributes of an optimum area depend on the degree to which wage and price
flexibility characterize the new region. If wages and prices are quite flexible in both the
currency board and reserve currency countries, then a case can be made that they should be
linked together with a fixed exchange rate (or, for that matter, with a common currency)
because both will respond in the same way to demand and supply shocks. It is often said
that wage and price flexibility is a key to the success of Hong Kong’s currency board. If the
degree of price and wage flexibility is quite different in the two countries, then the case for
a fixed exchange rate between them is weaker. However, there are a number of factors that
can substitute for price flexibility and, thus, warrant the establishment of a common

The Argentine peso was linked on a one-to-one basis to the U.S. dollar by a
currency board.17 Between mid-1995 and mid-2001, the U.S. dollar appreciated, in
real or inflation-adjusted terms against a market basket of 26 currencies, by about
33%. The increase raised the price of Argentine exports in foreign countries and
reduced the price of foreign goods in Argentina by roughly a comparable amount.
As a result, markets for Argentine exports withered and the people of Argentina
substituted cheaper foreign goods and services for comparable goods produced
domestically. The result was a trade deficit, an outflow of money to cover the deficit,
and constant deflationary pressure in Argentina. Because of the currency board,
Argentina could not alter the peso/dollar exchange rate. Rather, to restore
equilibrium with balanced international trade, Argentina had to rely on an increase
in unemployment to cause wages and prices to fall (with wages having to fall more
than prices). When the unemployment rate rose above 15% and the country was
threatened by extreme political instability, policymakers decided they could no longer
tolerate the consequences of continued deflation. They decided to abandon the
currency board and revert back to a central bank regime.
Typically, when the exchange rate is out of equilibrium, devaluation can help
an economy recover by making exports an import-competing goods more
competitive. What made Argentina’s problems so difficult to solve is that although

currency area. There are four major substitutes. First, how integrated are the two nation’s
financial systems? In other words, are interest rate changes highly correlated between the
two nations? The more complete the integration, the better. Second, what is the degree of
freedom with which labor and capital can move within the larger currency region? The
higher the degree of factor mobility, the stronger the case for a fixed exchange rate. Third,
what is the degree of mutual trade between the two countries? The more integrated the
goods and services markets and the larger the proportion of trade between the two countries,
the stronger is the case for a fixed exchange rate. Fourth, some individuals have argued that
the case for a fixed exchange rate embodied in a currency board regime is strengthened if
the political process in both countries is supportive of the fixed exchange rate relationship.
This requires a shared commitment to both fiscal and monetary stability, including fiscal
transfers when one region’s growth falls below the other’s. One can see that the 50 U.S.
states share all of these qualities, making the “shared” dollar a success. The literature on
“optimum currency areas” suggests that a currency board arrangement, whose purpose as
explained above is to achieve price stability would not be an optimum arrangement if both
countries did not possess a high degree of wage and price flexibility and the factors that
could substitute for or mitigate this difference are not present. Thus, one cannot make a
general case for or against currency boards. They must be evaluated on a case-by-case basis
depending on the degree to which they contribute to an optimum currency area. But it can
be argued empirically that most currency board countries tie their currency to reserve
countries that have economies with very little in common with their own. As a result, the
currency board country is frequently stuck with a monetary stance inconsistent with the
needs of its economy. For the seminal article in this literature, see Robert A. Mundell, “A
Theory of Optimum Currency Areas,” American Economic Review, vol. 51, September
1961, pp. 657-665.
17 One of the foremost experts on currency boards, Dr. Kurt Schuler, maintains that
Argentina did not operate an orthodox currency board. Rather, it is more appropriate to call
it a “convertibility” system. See Schuler, Kurt. “Was Argentina’s ‘Convertibility’ System
a Currency Board?” Unpublished paper. November 14, 2003.

the overvalued exchange rate had become highly deflationary, the currency board had
encouraged economic developments that made abandoning the currency board even
more damaging. For example, the Argentine banking system became highly dollar-
denominated. Following the devaluation, the entire banking system became
insolvent because the banks now needed more pesos to pay off their dollar-
denominated liabilities.
The Argentine example, the critics claim, contradicts the claim of currency
board proponents that currency boards eliminate the economic risks that prevent
developing countries from receiving foreign investment and enjoying the low interest
rates that U.S. borrowers enjoy. Currency boards only eliminate exchange rate risk.
In countries such as Argentina, they may in fact have increased economic risk,
leading to higher interest rates. Economic risk can be increased, as in Argentina, by
subjecting the country to exchange rate shocks that may have little to do with their
own economic and financial conditions. Rather, the country is exposed to the
international exchange rate behavior of the reserve country to which it has linked its
currencies and this can have serious adverse economic consequences when the
conditions for an optimum currency area do not prevail. Table 2 illustrates the
severity of the economic crisis that Argentina underwent before and after the
devaluation in 2001. In 2002, GDP shrank by nearly 11%, and output is still far
below its pre-crisis level.

Events in August 1998, the critics claim, also expose another weakness of a
currency board. The Hong Kong Monetary Authority, the official body responsible
for administering the Hong Kong currency board, alleged that hedge funds and other
large investors were participating in what they called a “double play” on Hong Kong
financial markets. It was alleged that these hedge funds were simultaneously short
selling securities on the Hong Kong stock market and selling Hong Kong dollars
back to the currency board. A short sale of an equity is a financial derivative contract
whereby the buyer profits if the equity price falls. As a result of the alleged double
play, the money supply shrank, the stock market fell 45% below its previous year
peak, and unemployment reached its highest level in 15 years. These activities
continued until the government interceded, purchasing 7.3% of the stock market’s

value at a cost of $15.2 billion with funds from previously accumulated budget
surpluses.18
Currency Boards Cannot Act as a Lender of Last Resort. Another
criticism made of currency boards is that they cannot fill a potentially vital role
played by central banks, that of a lender-of-last-resort to the nation’s financial
system. History is full of examples of bank panics. Some event causes individuals
to fear that banks will not be able to redeem their deposits in currency on demand.
When a large number of depositors suddenly demand conversion, most banks are not
in a position to honor their requests because banks do not hold large sums of
currency. However, banks usually make a good faith effort to do so and this means
trying to raise cash by selling assets or calling in loans. This has often involved
dealing in markets that are financially distressed with falling prices that do not reflect
the underlying value of the assets. One way to forestall a panic or prevent it from
reaching a panic state is for the monetary authority to buy these assets from banks or
make loans to them and, in the process, supply them with currency. When the public
becomes satisfied that it can get currency for its deposits, the panic will subside and
the destruction brought about by panic will be minimized.
All currency issued by a currency board is backed by foreign assets. But
currency boards do not back all bank deposits; only the fraction of bank deposits held
as reserves are in effect backed by foreign assets. Thus, all deposits could not be
honored by the currency board in the event of a bank run. Currency boards cannot
provide currency to banking institutions in such situations since increased issues of
currency depend on the acquisition of the reserve asset or currency which banks are
unlikely to possess. Thus, countries with currency boards must have other financial
arrangements for dealing with panics. Sometimes these are performed by the
national treasury departments. But only a central bank can expand overall liquidity
through its control of the money supply. A treasury can only shift purchasing power
from taxpayers or bondholders to the banking system, greatly weakening the lender-
of-last-resort function. However, some argue that the lender-of-last-resort function
has been largely abused in developing countries, creating moral hazard through the
bailout of well-connected financial actors. If that should be the case, the loss of the
lender-of-last-resort function may do more good than harm.19
18 Skeptics of the government claim that no “conspiracy” took place – hedge funds simply
sold the stock market short because of rational fears of the “Asian crisis” spreading to Hong
Kong. For a more detailed description of this event, see Financial Stability Forum, “Report
of the Working Group on Highly Leveraged Institutions,” March 2000, p. 130-132; “Fair
Shares,” The Economist, Oct. 29, 1998.
19 Proponents of currency boards have argued that foreign banks would probably come into
the market to spur competition and aid in development. The incentive to do so would be
especially strong for banks from the country whose currency is used as a reserve since there
would be no exchange rate risk between the local money and the reserve currency. They
argue that the presence of foreign banks which are branches of banks in the reserve currency
country would obviate the need for a lender of last resort. Thus, a desire to swap local
deposits for local currency is met by foreign banks borrowing reserve currency from their
head offices and using it to obtain local currency from the currency board. In effect, the
currency board country has had a sudden loan from the reserve currency country which

CRS-16
Setting up a Currency Board
To establish a currency board, a government must obtain assets on the basis of
which currency can be issued. The government (including any existing central bank)
may itself have a gold stock or be in possession of substantial foreign exchange
reserves. If not, the necessary foreign reserve currency would have to be acquired as
a gift or grant from the country whose currency is to serve as a reserve or obtained
from an international agency such as the IMF. Relevant to the IMF, on October 6,
1992, President George H.W. Bush signed the Foreign Operations Act (P.L. 102-391)
which allows the $12 billion U.S. quota increase to be used to “...support monetary
stability in member countries through the instrumentality of currency boards.”20
Once the board is established and the assets acquired, two basic options are
available. In the first, a new currency could be introduced and given (as a gift) to the
existing population according to a prearranged formula. At the same time, an
exchange rate would be established for the reserve currency or reserve asset. Once
the new money were introduced, it would become the functioning money of the
country. It would be used in transactions, held as a part of liquid wealth, and become
the unit in terms of which contracts are written and prices quoted. Should an existing
currency be in circulation at the time a new currency board money is introduced, it
could continue to circulate and exchange for the new currency at whatever rate was
dictated by the market. If the existing currency has legal tender status, it is important
that similar status be accorded the notes of the currency board. Presumably, as the
new currency took hold, it would drive the existing currency out of circulation.
As an alternative, an existing currency could be used which would now become
the liability of the currency board. All foreign exchange or precious metals held by
the government and central bank would simultaneously be transferred to the currency
board and become its assets and would then be valued in terms of the reserve
currency. Under this option, as in the other, an exchange rate would have to be fixed
relative to the reserve currency or asset such that the reserves of the currency board
backed 100% of the existing currency. In addition, since the exchange rate would be
the rate at which local prices are converted into world prices and vice versa, it should
not be too high so that exports are discouraged and imports encouraged nor too low
so that exports are in effect subsidized and imports taxed. Thus, the exchange rate
should be one that reflects, to the extent possible, market conditions.
To maintain the independence of any currency board and to safeguard the assets
held by the board from government confiscation, proponents have argued for two
legal safeguards. First, a majority of board members appointed would be foreign
nationals. Second, the assets of the board would be deposited in a foreign country

enables it to meet a sudden demand for currency. There is no guarantee that this loan would
occur, however. The foreign bank may prefer to curtail its lending instead. It is also
uncertain how a demand could be met in the absence of foreign branch banks.
20 Another possibility is for the currency board to pay a slight premium for foreign currency
in order to build up its assets. The subsequent profit from its portfolio could be used to pay
off the cost of the premium.

such as Switzerland or Sweden with the proviso that the governments of the new
currency board states would be denied access to the funds.
Concluding Comments
While the introductory discussion of a currency board suggested that it would
be a radical departure from the way that monetary policy is presently conducted in
the United States, it may not be such a radical alternative for countries that are just
acquiring control over their own monetary arrangements, have experienced a
currency crisis, or who have had a history of chronic inflation. This may account for
its adoption by Argentina, Bulgaria, Lithuania, Estonia, and explain why Indonesia
briefly considered adopting it during the Asian crisis.
Currency board proponents base their case on an argument that is essentially
political – countries with profligate pasts need to have their “hands tied” by a
currency board to prevent bad policymaking in the future. In evaluating the relevance
of currency boards for various countries, it is useful to avoid comparing them to some
ideal monetary system. Rather, proponents argue, currency boards should be
compared to central banking regimes now in operation in these countries, whose
performance may in some instances serve as an impediment to the development of
a market economy, at that stage of the country’s economic development.
The case for currency boards is based on their ability to supply a currency that
is both internally and externally convertible, and is backed 100% by reserves of either
precious metal or foreign currencies. The case is strengthened when it is pointed out
that they cannot alter the domestic money supply through transactions in assets
denominated in local currency.
As such, proponents argue that currency boards are an attractive alternative to
central banks for introducing a stable valued money that could fulfill the role of unit
of account, medium of exchange, and store of value. Success in these roles could
shore up the development of market economies, encourage the development of
financial institutions, and encourage financial integration with the reserve currency
country.
In addition, currency boards would have a restraining influence on fiscal policy
in these countries. Essentially, they would make it impossible to finance budget
deficits through a central banking printing press. This accomplishment alone would
contribute markedly to price level stability, which could speed up the process of
international investment needed for modernizing and unleashing the productive
potential of many nations.
Potential shortcomings of this regime, however, are several. Currency boards
cannot serve as lenders-of-last-resort and the economies of currency board countries
are exposed to all the shocks that affect the external value of the currency which
serves as the basis of their reserves. In the face of these shocks, the entire adjustment
in currency board countries is placed on real wages and real interest rates if excessive
unemployment and slower than normal GDP growth is be avoided. In typical
monetary arrangements, economic adjustment could come about through exchange

CRS-18
rate adjustment. But with a currency board, exchange rate adjustment could only
come about by abandoning the currency board, which, experience shows, would
likely trigger a financial crisis.
For a currency board to deliver stable economic growth, the country must tie its
currency to a country that experiences similar economic shocks and conditions in
order to enjoy a monetary policy appropriate for its economy. Otherwise, as the
Argentine case illustrates, a currency board country is likely to experience periods of
recession brought on by an incompatible exchange rate. The problem here is that
most countries currently considering currency boards are developing countries or
those emerging from decades of central planning with a poor or incomplete fiscal and
monetary policy track record. Since they hope to restore or gain confidence through
the adoption of a currency board, they are seeking a reserve country with a high
degree of monetary credibility, most likely one of the world’s major currencies – the
dollar, the euro, the Swiss franc, the British pound, or the yen. But in most cases, the
shocks affecting the economies of developing countries would have very little in
common with the shocks affecting the economies of the five major currencies. For
that reason, developing countries that adopt a currency board risk experiencing the
same problems that plagued Argentina and, ultimately, caused it to abandon its
currency board for a central bank regime, triggering economic and financial collapse
in the process.
