When Is Exchange-Rate Targeting Desirable for Emerging Market Countries?

In countries whose political and monetary institutions are particularly weak and who therefore have been experiencing continued bouts of hyperinflation, a characterization that applies to many emerging market (including transition) countries, exchangerate targeting may be the only way to break inflationary psychology and stabilize the economy. In this situation, exchange-rate targeting is the stabilization policy of last resort. However, if the exchange-rate targeting regimes in emerging market countries are not always transparent, they are more likely to break down, often resulting in disastrous financial crises.

Are there exchange-rate strategies that make it less likely that the exchange-rate regime will break down in emerging market countries? Two such strategies that have received increasing attention in recent years are currency boards and dollarization.

Currency Boards

A detailed discussion of the history, purpose, and function of currency boards.

One solution to the problem of lack of transparency and commitment to the exchangerate target is the adoption of a currency board, in which the domestic currency is backed 100% by a foreign currency (say, dollars) and in which the note-issuing authority, whether the central bank or the government, establishes a fixed exchange rate to this foreign currency and stands ready to exchange domestic currency for the foreign currency at this rate whenever the public requests it. A currency board is just a variant of a fixed exchange-rate target in which the commitment to the fixed exchange

rate is especially strong because the conduct of monetary policy is in effect put on autopilot, taken completely out of the hands of the central bank and the government. In contrast, the typical fixed or pegged exchange-rate regime does allow the monetary authorities some discretion in their conduct of monetary policy because they can still adjust interest rates or print money.

A currency board arrangement thus has important advantages over a monetary policy strategy that just uses an exchange-rate target. First, the money supply can expand only when foreign currency is exchanged for domestic currency at the central bank. Thus the increased amount of domestic currency is matched by an equal increase in foreign exchange reserves. The central bank no longer has the ability to print money and thereby cause inflation. Second, the currency board involves a stronger commitment by the central bank to the fixed exchange rate and may therefore be effective in bringing down inflation quickly and in decreasing the likelihood of a successful speculative attack against the currency.

Although they solve the transparency and commitment problems inherent in an exchange-rate target regime, currency boards suffer from some of the same shortcomings: the loss of an independent monetary policy and increased exposure of the economy to shocks from the anchor country, and the loss of the central bankÕs ability to create money and act as a lender of last resort. Other means must therefore be used to cope with potential banking crises. Also, if there is a speculative attack on a currency board, the exchange of the domestic currency for foreign currency leads to a sharp contraction of the money supply, which can be highly damaging to the economy.

Currency boards have been established recently in countries such as Hong Kong (1983), Argentina (1991), Estonia (1992), Lithuania (1994), Bulgaria (1997), and Bosnia (1998). ArgentinaÕs currency board, which operated from 1991 to 2002 and required the central bank to exchange U.S. dollars for new pesos at a fixed exchange rate of 1 to 1, is one of the most interesting. Box 1 describes ArgentinaÕs experience with its currency board.

Another solution to the problems created by a lack of transparency and commitment to the exchange-rate target is dollarization, the adoption of a sound currency, like the U.S. dollar, as a countryÕs money. Indeed, dollarization is just another variant of a fixed exchange-rate target with an even stronger commitment mechanism than a currency board provides. A currency board can be abandoned, allowing a change in the value of the currency, but a change of value is impossible with dollarization: a dollar bill is always worth one dollar whether it is held in the United States or outside of it.

Dollarization has been advocated as a monetary policy strategy for emerging market countries: It has been discussed actively by Argentine officials in the aftermath of the devaluation of the Brazilian real in January 1999 and was adopted by Ecuador in March 2000. DollarizationÕs key advantage is that it completely avoids the possibility of a speculative attack on the domestic currency (because there is none). (Such an attack is still a danger even under a currency board arrangement.)

Dollarization is subject to the usual disadvantages of an exchange-rate target (the loss of an independent monetary policy, increased exposure of the economy to shocks from the anchor country, and the inability of the central bank to create money and act as a lender of last resort). Dollarization has one additional disadvantage not characteristic of currency boards or other exchange-rate target regimes. Because a country adopting dollarization no longer has its own currency it loses the revenue that a government receives by issuing money, which is called seignorage. Because governments

Targeting in

and Switzerland

In many countries, exchange-rate targeting is not an option, because either the country (or bloc of countries) is too large or because there is no country whose currency is an obvious choice to serve as the nominal anchor. Exchange-rate targeting is therefore clearly not an option for the United States, Japan, or the European Monetary Union. These countries must look to other strategies for the conduct of monetary policy, one of which is monetary targeting.

In the 1970s, monetary targeting was adopted by several countries, notably Germany, Switzerland, Canada, the United Kingdom, and Japan, as well as in the United States (already discussed in Chapter 18). This strategy involves using monetary aggregates as an intermediate target of the type described in Chapter 18 to achieve an ultimate goal such as price stability. Monetary targeting as practiced was quite different from Milton FriedmanÕs suggestion that the chosen monetary aggregate be targeted to grow at a constant rate. Indeed, in all these countries the central banks never adhered to strict, ironclad rules for monetary growth and in some of these countries monetary targeting was not pursued very seriously.

Canada and the United Kingdom. In a move similar to that made by the United States, the Bank of Canada responded to a rise in inflation in the early 1970s by introducing a program of monetary targeting referred to as Òmonetary gradualism.Ó Under this policy, which began in 1975, M1 growth would be controlled within a gradually falling target range. The British introduced monetary targeting in late 1973, also in response to mounting concerns about inflation. The Bank of England targeted M3, a broader monetary target than the Bank of Canada or the Fed used.

By 1978, only three years after monetary targeting had begun, the Bank of Canada began to distance itself from this strategy out of concern for the exchange rate. Because of the conflict with exchange-rate goals, as well as the uncertainty about M1 as a reliable guide to monetary policy, the M1 targets were abandoned in November 1982. Gerald Bouey, then governor of the Bank of Canada, described the situation by saying, ÒWe didnÕt abandon monetary aggregates, they abandoned us.Ó

In the United Kingdom, after monetary aggregates overshot their targets and inflation accelerated in the late 1970s, Prime Minister Margaret Thatcher in 1980 introduced the Medium-Term Financial Strategy, which proposed a gradual deceleration of M3 growth. Unfortunately, the M3 targets ran into problems similar to those of the M1 targets in the United States: They were not reliable indicators of the tightness of monetary policy. After 1983, arguing that financial innovation was wreaking havoc with the relationship between M3 and national income, the Bank of England began to de-emphasize M3 in favor of a narrower monetary aggregate, M0 (the monetary base). The target for M3 was temporarily suspended in October 1985 and was completely dropped in 1987.

A feature of monetary targeting in Canada and especially in the United Kingdom was that there was substantial game playing: Their central banks targeted multiple aggregates, allowed base drift (by applying target growth rates to a new base at which the target ended up every period), did not announce targets on a regular schedule, used artificial means to bring down the growth of a targeted aggregate, often overshot their targets without reversing the overshoot later, and often obscured why deviations from the monetary targets occurred.

of the shocks to the exchange rate and the shift in the demand for monetary base arising from the above institutional changes created a serious problem for its targeted aggregate. As the 1988 year unfolded, it became clear that the Swiss National Bank had guessed wrong in predicting the effects of these shocks, so that monetary policy was too easy, even though the monetary target was undershot. The result was a subsequent rise in inflation to above the 5% level.

As a result of these problems with monetary targeting Switzerland substantially loosened its monetary targeting regime (and ultimately, adopted inflation targeting in 2000). The Swiss National Bank recognized that its money growth targets were of diminished utility as a means of signaling the direction of monetary policy. Thus, its announcement at the end of 1990 of the medium-term growth path did not specify a horizon for the target or the starting point of the growth path. At the end of 1992, the bank specified the starting point for the expansion path, and at the end of 1994, it announced a new medium-term path for money base growth for the period 1995 to 1999. By setting this path, the bank revealed retroactively that the horizon of the first path was also five years (1990Ð1995). Clearly, the Swiss National Bank moved to a much more flexible framework in which hitting one-year targets for money base growth has been abandoned. Nevertheless, Swiss monetary policy continued to be successful in controlling inflation, with inflation rates falling back down below the 1% level after the temporary bulge in inflation from 1989 to 1992.

There are two key lessons to be learned from our discussion of German and Swiss monetary targeting. First, a monetary targeting regime can restrain inflation in the longer run, even when the regime permits substantial target misses. Thus adherence to a rigid policy rule has not been found to be necessary to obtain good inflation outcomes. Second, the key reason why monetary targeting has been reasonably successful in these two countries, despite frequent target misses, is that the objectives of monetary policy are clearly stated and both the central banks actively engaged in communicating the strategy of monetary policy to the public, thereby enhancing the transparency of monetary policy and the accountability of the central bank.

As we will see in the next section, these key elements of a successful targeting regimeÑflexibility, transparency, and accountabilityÑare also important elements in inflation-targeting regimes. German and Swiss monetary policy was actually closer in practice to inflation targeting than it was to Friedman-like monetary targeting, and thus might best be thought of as ÒhybridÓ inflation targeting.

A major advantage of monetary targeting over exchange-rate targeting is that it enables a central bank to adjust its monetary policy to cope with domestic considerations. It enables the central bank to choose goals for inflation that may differ from those of other countries and allows some response to output fluctuations. Also, as with an exchange-rate target, information on whether the central bank is achieving its target is known almost immediatelyÑfigures for monetary aggregates are typically reported within a couple of weeks. Thus, monetary targets can send almost immediate signals to the public and markets about the stance of monetary policy and the intentions of the policymakers to keep inflation in check. In turn, these signals help fix inflation expectations and produce less inflation. Monetary targets also allow almost immediate accountability for monetary policy to keep inflation low, thus helping to constrain the monetary policymaker from falling into the timeconsistency trap.

All of the above advantages of monetary aggregate targeting depend on a big if: There must be a strong and reliable relationship between the goal variable (inflation or nominal income) and the targeted aggregate. If the relationship between the monetary aggregate and the goal variable is weak, monetary aggregate targeting will not work; this seems to have been a serious problem in Canada, the United Kingdom, and Switzerland, as well as in the United States. The weak relationship implies that hitting the target will not produce the desired outcome on the goal variable and thus the monetary aggregate will no longer provide an adequate signal about the stance of monetary policy. As a result, monetary targeting will not help fix inflation expectations and be a good guide for assessing the accountability of the central bank. In addition, an unreliable relationship between monetary aggregates and goal variables makes it difficult for monetary targeting to serve as a communications device that increases the transparency of monetary policy and makes the central bank accountable to the public.

Given the breakdown of the relationship between monetary aggregates and goal variables such as inflation, many countries that want to maintain an independent monetary policy have recently adopted inflation targeting as their monetary policy regime. New Zealand was the first country to formally adopt inflation targeting in 1990, followed by Canada in 1991, the United Kingdom in 1992, Sweden and Finland in 1993, and Australia and Spain in 1994. Israel, Chile, and Brazil, among others, have also adopted a form of inflation targeting.

Inflation targeting involves several elements: (1) public announcement of medium-term numerical targets for inflation; (2) an institutional commitment to price stability as the primary, long-run goal of monetary policy and a commitment to achieve the inflation goal; (3) an information-inclusive strategy in which many variables and not just monetary aggregates are used in making decisions about monetary policy; (4) increased transparency of the monetary policy strategy through communication with the public and the markets about the plans and objectives of monetary policymakers; and (5) increased accountability of the central bank for attaining its inflation objectives.
