Before the crisis of 1997-98, the East Asian economies except for Japan but including China pegged their currencies to the U.S. dollar. To avoid further turmoil, the IMF now argues that these currencies should float more freely. However, our econometric estimations show that the dollar's...

We investigate the drivers of daily changes in the exchange value of the Chinese currency (CNY) since early 2016, when a new regime was introduced for setting the fix - the midpoint of the CNY's daily trading range against the U.S. dollar. Daily changes in the fix, which is announced just prior...

The share of U.S. dollar assets in the official foreign exchange reserve portfolios of central banks is sometimes taken as an indicator of dollar status. We show that the observed decline in the aggregate share of U.S. dollar assets does not stem from a systematic shift in currency preferences...

We study the effects of an anticipated dollarization, announced today but planned to be implemented at some future date, in a simple open-economy model. Motivated by the profile of countries considering dollarization we make the following assumptions. First, the government faces a scarcity of...

There is often speculation that the international roles of currencies may be changing. This paper presents the current status of these roles. The U.S. dollar continues to be the dominant currency across various uses. Yet, such a role may change over time. If this occurs, there could be...

We analyze a large number of industry- and company-level filings of global institutional investors to provide the first comprehensive estimate of foreign investors' U.S. dollar (USD) security holdings and currency hedging practices. We document four stylized facts. First, driven by increasing...

We find that variation in expected U.S. productivity explains over half of U.S. dollar/G7 exchange rate fluctuations. Both correctly-anticipated changes in productivity and expectational noise, which influences the expectation of productivity but not its eventual realization, have large effects....

Building on the facility design and application experience from the period of the global financial crisis, in March 2020 the Federal Reserve eased the terms on its standing swap lines in collaboration with other central banks, reactivated temporary swap agreements, and then introduced the new...

We provide a liquidity-based theory for the dominant use of the US dollar as the unit of denomination in global debt contracts. Firms need to trade their revenue streams for the assets required to extinguish their debt obligations. When asset markets are illiquid, as modeled via endogenous...

Recent trends suggest the world economy may be tending towards an equilibrium with two distinct trading blocs, each internally integrated, but with significant isolation between the blocs. This paper uses a quantitative theory to explore how far this bifurcation would need to go to pose a threat...
