Financially closed economies insure themselves against current-account shocks using international reserves. We characterize the optimal management of reserves using an open-economy model of precautionary savings and emphasize several results. First, the welfare-based opportunity cost of reserves...

The heightened volatility of commodity prices in recent years, reflecting the effects of the pandemic and the war in Ukraine, begs the longstanding question of the optimal fiscal policy response to commodity price shocks. Fiscal performance in most commodity-exporting countries is typically...

Views on the effectiveness of sterilized reserve intervention vary. Sterilized intervention is generally seen as ineffective in advanced countries while persistent intervention by some emerging markets is often cited as contributing to undervalued exchange rates and current account surpluses....

The accumulation of large foreign asset positions by many central banks through sustained foreign exchange (FX) intervention has raised questions about its associated fiscal costs. This paper clarifies conceptual issues regarding how to measure these costs both from an ex-post and an ex-ante...

This paper offers an empirical model of the drivers of the level of the Real Effective Exchange Rate (REER) that is now part of the IMF's methodology for the assessment of external positions, including exchange rates. It constructs a measure of the level of the REER and it offers a panel...

The External Balance Assessment (EBA) methodology has been developed by the IMF's Research Department as a successor to the CGER methodology for assessing current accounts and exchange rates in a multilaterally consistent manner. Compared to other approaches, EBA emphasizes distinguishing...

Motivated by the tension first revealed during the global financial crisis between thedomestic and international financial stability obligations of central bank reserve managers,this paper offers some reflections along four main lines. First, the paper highlights howofficial reserve management...

All types of recessions, on average, not just those associated with financial and political crises (as in Cerra and Saxena, AER 2008), lead to permanent output losses. These findings have far-reaching conceptual and policy implications. A new paradigm of the business cycle needs to account for...

We document a decline in the dollar share of international reserves since the turn of the century. This decline reflects active portfolio diversification by central bank reserve managers; it is not a byproduct of changes in exchange rates and interest rates, of reserve accumulation by a small...

This paper studies the role of an increase in foreign exchange reserves in reducing currency volatility for emerging market countries. The study employs a panel of 28 countries over the period 1986-2002. Several control variables are introduced in the regressions to account for other factors...
