Several Asian emerging market economies have recently adopted measures to limit the offshore trading of their currencies. This paper provides a general overview of such measures and evaluates the experiences of selected countries that resorted to such measures. It concludes that the measures could be effective if they were comprehensive and effectively enforced, and were accompanied by consistent macroeconomic policies and structural reforms. Such measures, however, could adversely affect investor confidence, financial market development, and nonspeculative economic and financial activities, and impose administrative burden on all parties involved.

Non-deliverable forward (NDF) markets in many Asian emerging market currencies are large, rapidly growing, and often exceed onshore markets in transaction volume. NDFs tend to price significant depreciation during market stress episodes including COVID-19. Spillovers from NDFs to onshore markets are a policymaker concern. Our analysis shows that influences tend to run both ways after controlling for differences in timezones between markets. For the COVID-19 pandemic there is some evidence of NDFs leading onshore markets for a few currencies. Policy approaches to NDFs vary widely across Asia from close integration with onshore markets to severe restrictions on NDF trading.

This paper presents a rule for foreign exchange interventions (FXI), designed to preserve financial stability in floating exchange rate arrangements. The FXI rule addresses a market failure: the absence of hedging solution for tail exchange rate risk in the market (i.e. high volatility). Market impairment or overshoot of exchange rate between two equilibria could generate high volatility and threaten financial stability due to unhedged exposure to exchange rate risk in the economy. The rule uses the concept of Value at Risk (VaR) to define FXI triggers. While it provides to the market a hedge against tail risk, the rule allows the exchange rate to smoothly adjust to new equilibria. In addition, the rule is budget neutral over the medium term, encourages a prudent risk management in the market, and is more resilient to speculative attacks than other rules, such as fixed-volatility rules. The empirical methodology is backtested on Banco Mexico’s FXIs data between 2008 and 2016.

The role of the Japanese yen as an international currency is assessed. It is found that the determinants of international-currency use imply some increase for the yen’s use in international finance; however, the implications for the yen’s use in international trade are mixed. It is also shown that, despite Japan’s emergence as the world’s largest net creditor nation, Japan’s capital outflows have not significantly facilitated the yen’s internationalization. Data are presented showing that, although the yen’s use as an international currency has increased, it is still rather modest. Wider use of the yen as a regional currency in Asia has occurred, though a “yen-zone” does not appear to be emerging.

The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.

The book includes selected papers of Morris Goldstein on the following topics in international macroeconomics: international trade, currency regimes, exchange rate policy, international policy coordination, banking, financial crises, financial regulation, IMF policies, and China's exchange rate policy. Some of the papers are empirical in nature, while others address key policy issues in international macroeconomics. Many of the papers are co-authored with other well-known international economists, including Jacob Frenkel, Mohsin Khan, Nicholas Lardy, Peter Montiel, Michael Mussa, Carmen Reinhart, and Philip Turner, among others. Taken as a group, the papers should give the reader a good picture of many of the most important issues in international macroeconomics over the past 35 years.
