Foreign exchange intervention is widely used as a policy tool, particularly in emerging markets, but many facets of this tool remain limited, especially in the context of flexible exchange rate regimes. The Latin American experience can be informative because some of its largest countries adopted floating exchange rate regimes and inflation targeting while continuing to intervene in foreign exchange markets. This edited volume reviews detailed accounts from several Latin American countries’ central banks, and it provides insight into how and with what aim many interventions were decided and implemented. This book documents the effectiveness of intervention and pays special attention to the role of foreign exchange intervention policy within inflation-targeting monetary frameworks. The main lesson from Latin America’s foreign exchange interventions, in the context of inflation targeting, is that the region has had a considerable degree of success. Transparency and a clear communication policy have been key. For economies that are not highly dollarized, rules-based intervention helped contain financial instability and build international reserves while preserving inflation targets. The Latin American experience can help other countries in the design and implementation of their policies.

The paper documents the use of foreign exchange intervention (FXI) across countries and monetary regimes, with special attention to its use under inflation targeting (IT). We find significant differences between advanced and emerging market economies, with the former group conducting FXI limitedly and broadly symmetrically, while the use of this policy instrument in emerging market countries is pervasive and mostly asymmetric (biased towards purchasing foreign currency, even after taking into account precautionary motives). Within emerging markets, the use of FXI is common both under IT and non-IT regimes. We find no evidence of FXI being used in response to inflation developments, while there is strong evidence that FXI responds to exchange rates, indicating that IT central banks in EMDEs have dual inflation/exchange rate objectives. We also find a higher propensity to overshoot inflation targets in emerging market economies where FXI is more pervasive.

This paper provides a brief historical journey of central banking in Latin America to shed light on the debate about monetary policy in the post-global financial crisis period. The paper distinguishes three periods in Latin America’s central bank history: the early years, when central banks endorsed the gold standard and coped with the collapse of this monetary system; a second period, in which central banks turned into development banks under the aegis of governments at the expense of increasing inflation; and the “golden years,” when central banks succeeded in preserving price stability in an environment of political independence. The paper concludes by cautioning against overburdening central banks in Latin America with multiple mandates as this could end up undermining their hard-won monetary policy credibility.

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.

We investigate the motives inflation-targeting central banks in emerging markets may have for intervening in foreign exchange markets and evaluate the case for such interventions based on the existing literature. Our findings suggest that the rationale for interventions depends on initial conditions and country-specific circumstances. The case is strongest in the presence of large currency mismatches or underdeveloped markets. While interventions can have benefits in the short-term, sustained over time they could entrench unfavorable initial conditions, though more work is needed to establish this empirically. A first effort to measure the cost of interventions to the credibility of policy frameworks suggests that the negative impact may be smaller than often assumed—at least for the set of more sophisticated inflation-targeting emerging-market central banks considered here.

How should governments and central banks use monetary policy to create a healthy economy? Traditionally, policymakers have used such strategies as controlling the growth of the money supply or pegging the exchange rate to a stable currency. In recent years a promising new approach has emerged: publicly announcing and pursuing specific targets for the rate of inflation. This book is the first in-depth study of inflation targeting. Combining penetrating theoretical analysis with detailed empirical studies of countries where inflation targeting has been adopted, the authors show that the strategy has clear advantages over traditional policies. They argue that the U.S. Federal Reserve and the European Central Bank should adopt this strategy, and they make specific proposals for doing so. The book begins by explaining the unique features and advantages of inflation targeting. The authors argue that the simplicity and openness of inflation targeting make it far easier for the public to understand the intent and effects of monetary policy. This strategy also increases policymakers' accountability for inflation performance and can accommodate flexible, even "discretionary," monetary policy actions without sacrificing central banks' credibility. The authors examine how well variants of this approach have worked in nine countries: Germany and Switzerland (which employ a money-focused form of inflation targeting), New Zealand, Canada, the United Kingdom, Sweden, Israel, Spain, and Australia. They show that these countries have typically seen lower inflation, lower inflation expectations, and lower nominal interest rates, and have found that one-time shocks to the price level have less of a "pass-through" effect on inflation. These effects, in turn, are improving the climate for economic growth. The authors warn, however, that the success of inflation targeting depends on operational details, such as how the targets are defined and when they are announced. They also show that inflation targeting is not a panacea that can make inflation perfectly predictable or reduce it without economic costs. Clear, balanced, and authoritative, Inflation Targeting is a groundbreaking study that will have a major impact on the debate over the right monetary strategy for the coming decades. As a unique comparative study of what central banks actually do in different countries around the world, this book will also be invaluable to anyone interested in how economic policy is made.

Over the past two decades, many low- and lower-middle income countries (LLMICs) have improved control over fiscal policy, liberalized and deepened financial markets, and stabilized inflation at moderate levels. Monetary policy frameworks that have helped achieve these ends are being challenged by continued financial development and increased exposure to global capital markets. Many policymakers aspire to move beyond the basics of stability to implement monetary policy frameworks that better anchor inflation and promote macroeconomic stability and growth. Many of these LLMICs are thus considering and implementing improvements to their monetary policy frameworks. The recent successes of some LLMICs and the experiences of emerging and advanced economies, both early in their policy modernization process and following the global financial crisis, are valuable in identifying desirable features of such frameworks. This paper draws on those lessons to provide guidance on key elements of effective monetary policy frameworks for LLMICs.

Foreign exchange intervention (FXI) is a highly debated topic. Yet, comprehensive and comparable data on FXI is hard to find. This paper provides a new dataset of FXI covering a large number of countries over the period 2000-20 at monthly and quarterly frequencies. It includes publicly available data for about 40 countries and carefully constructed proxies for 122 countries. Proxies are focused on both spot and derivative transactions that alter the central bank’s foreign currency position and account for a wide range of central bank operations, including vis-à-vis residents, the first proxy to do so to our knowledge. The paper discusses the merits of the new proxy relative to coarser measures traditionally used like the change in reserves, and potential definitional differences with published data. The paper also presents stylized facts using our newly constructed FXI proxies.
