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...

Building on the vast literature, this paper focuses on the role of the structure of the international investment position (IIP) in affecting countries' external vulnerabilities. Using a sample of 73 advanced and emerging economies and new database on the IIP's currency composition, we find that...

Why did monetary authorities hold large gold reserves under Bretton Woods (1944-1971) when only the US had to? We argue that gold holdings were driven by institutional memory and persistent habits of central bankers. Countries continued to back currency in circulation with gold reserves,...

This paper provides a dataset on the currency composition of the international investment position for a group of 50 countries for the period 1990-2017. It improves available data based on estimates by incorporating actual data reported by statistical authorities and refining estimation methods....

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...

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...

Financial globalization was off to a rocky start in emerging economies hit by Sudden Stops in the 1990s. The surge in foreign reserves since then is viewed as a New Merchantilism in which reserves are a war-chest for defense against Sudden Stops. We conduct a quantitative assessment of this...

This paper examines the (quasi-)fiscal impact of the (opportunity) cost of international reserves. It proposes a conceptual framework, with particular emphasis on two hitherto somewhat neglected aspects: a more appropriate measure of gross opportunity cost, and potential savings from lower...
