This paper explores the role of exchange rates in emerging economies with inflation-targeting regimes, an issue that has become especially germane during the current episode of financial turmoil and volatile capital flows. Under inflation targeting, the interest rate is the main monetary policy tool for influencing activity and inflation, and there is little agreement about the appropriate role of the exchange rate.The exchange rate is a more important monetary policy tool for emerging economies that have adopted inflation targeting than it is for inflation-targeting advanced economies. Inflation-targeting emerging economies generally have less flexible exchange rate arrangements and intervene more frequently in the foreign exchange market than their advanced economy counterparts. The enhanced role of the exchange rate reflects these economies' greater vulnerability to exchange rate shocks and their less developed financial markets. However, their sharper focus on the exchange rate may cause some confusion about the commitment of their central banks to achieve the inflation target and may also complicate policy implementation. Global inflation pressures, greater exchange rate volatility, and the financial stresses from the global financial turmoil that began in mid-2007 are heightening these tensions.

This is the fifth chapter of a forthcoming monograph entitled "On Implementing Full-Fledged Inflation-Targeting Regimes: Saying What You Do and Doing What You Say." It examines whether certain conditions have to be met before emerging economies can adopt an inflation-targeting regime and provides some empirical evidence on the matter. The issues analyzed are the priority of inflation targeting over other goals, the absence of fiscal dominance, central bank independence, the degree of control over the policy interest rate, a sound methodology for forecasting, and the soundness of financial institutions and markets, and resilience to changes in exchange rates and interest rates.

This book, based on the proceedings of a conference organised by the OECD and the Bank of England's Centre for Banking Studies, examines cross-country issues related to the conduct of monetary policy in emerging markets and the role of inflation targeting in improving macroeconomic performance.

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.

Staff Discussion Notes showcase the latest policy-related analysis and research being developed by individual IMF staff and are published to elicit comment and to further debate. These papers are generally brief and written in nontechnical language, and so are aimed at a broad audience interested in economic policy issues. This Web-only series replaced Staff Position Notes in January 2011.

A growing number of countries are anchoring their monetary policy through explicit inflation targeting. This policy has already scored remarkable successes in several countries, establishing central bank credibility, and reining in inflation where it had long been stubbornly high. But implementing inflation targets raises many difficult questions. What prerequisites must an economy and its institutions meet for the strategy to work? What choices should central banks make from the menu of possible variations on the basic approach? This book summarizes the discussions in a seminar at which economists and policymakers from ten countries reviewed their experiences with inflation targeting.

We analyze coordination of monetary and exchange rate policy in a two-sector model of a small open economy featuring imperfect substitution between domestic and foreign financial assets. Our central finding is that management of the exchange rate greatly enhances the efficacy of inflation targeting. In a flexible exchange rate system, inflation targeting incurs a high risk of indeterminacy where macroeconomic fluctuations can be driven by self-fulfilling expectations. Moreover, small inflation shocks may escalate into much larger increases in inflation ex post. Both problems disappear when the central bank leans heavily against the wind in a managed float.
