Exchange Rate Regimes For Emerging Markets

In the aftermath of the Asian/global financial crises of 1997-98, how should emerging markets now structure their exchange rate systems to prevent new crises from occurring? This study challenges current orthodoxy by advocating the revival of intermediate exchange rate regimes. In so doing, Williamson presents a reasoned challenge to the new prevailing attitude which claims that all countries involved in the international capital markets need to polarize to one of the extreme regimes (to a fixed rate with either a currency board or dollarization, or to a lightly-managed float). He concludes that although there is some truth in the allegation that intermediate regimes are vulnerable to speculative crises, they still offer offsetting advantages. He also contends that it would be possible to redesign them to be more flexible so as to reduce their vulnerability to crises.

This paper investigates the effects of the adoption of inflation targeting (IT) on the choice of exchange rate regime in emerging markets (EMs), conditional on certain macroeconomic conditions. Using a large sample of EMs and after controlling for the selection bias associated with the adoption of IT, we find that IT countries on average have a relatively more flexible exchange rate regime than other EMs. However, the flexibility of the exchange rate regime shows strong heterogeneity among IT countries depending on their degree of openness and exposure to FX risks. Moreover, we find that the marginal effect of IT adoption on the exchange rate flexibility increases with the duration of the IT regime in place, and with the propensity scores to adopt it.

We characterize a country's exchange rate regime by how its central bank channels a capital account shock across three variables: exchange depreciation, interest rates, and international reserve flows. Structural vector autoregression estimates for Brazil, Mexico, and Turkey reveal such responses, both contemporaneously and over time. Capital account shocks are further shown to affect output growth and inflation. The nature and magnitude of these effects may depend on the exchange rate regime.

Using recent advances in the classification of exchange rate regimes, this paper finds no support for the popular bipolar view that countries will tend over time to move to the polar extremes of free float or rigid peg. Rather, intermediate regimes have shown remarkable durability. The analysis suggests that as economies mature, the value of exchange rate flexibility rises. For countries at a relatively early stage of financial development and integration, fixed or relatively rigid regimes appear to offer some anti-inflation credibility gain without compromising growth objectives. As countries develop economically and institutionally, there appear to be considerable benefits to more flexible regimes. For developed countries that are not in a currency union, relatively flexible exchange rate regimes appear to offer higher growth without any cost in credibility.

In this paper, I survey the issue of exchange rate regime choice from the perspective of both the industrial and emerging economies taking an historical perspective. I first survey the theoretical issues beginning with a taxonomy of regimes. I then examine the empirical evidence on the delineation of regimes and their macroeconomic performance. The penultimate section provides a brief history of monetary regimes in industrial and emerging economies. The conclusion considers the case for a managed float regime for today's emerging economies.

Some emerging economies have a relatively ineffective monetary policy transmission owing to weaknesses in the domestic financial system and the presence of a large and segmented informal sector. At the same time, small open economies can have a substantial monetary policy transmission through the exchange rate channel. In order to understand this setting, we explore a unified treatment of monetary policy transmission and exchangerate pass-through. The results for an emerging market, India, suggest that the most effective mechanism through which monetary policy impacts inflation runs through the exchange rate.

With the loss of Soviet control in Central and Eastern Europe, as well as the move toward economic liberalization in many developing countries, a huge increase in the number of convertible currencies in the world has occurred. A key aspect of the management of these currencies involves their relationships with the world economy, which is determined

A growing number of countries are adopting flexible exchange rate regimes because flexibility offers more protection against external shocks and greater monetary independence. Other countries have made the transition under disorderly conditions, with the sharp depreciation of their currency during a crisis. Regardless of the reason for adopting a flexible exchange rate, a successful transition depends on the effective management of a number of institutional and operational issues. The authors of this Economic Issue describe the necessary ingredients for moving to a flexible regime, as well as the optimal pace and sequencing under different conditions.
