The U.S. dollar exchange rate clears the global market for dollar-denominated safe assets. We find that shifts in the demand and supply of safe dollar assets are important drivers of variation in the dollar exchange rate, bond yields, and other global financial variables. An increase in the...

We develop a theory that links the U.S. dollar's valuation in FX markets to the convenience yield that foreign investors derive from holding U.S. safe assets. We show that this convenience yield can be inferred from the Treasury basis: the yield gap between U.S. government and currency-hedged...

We build a model of the global financial cycle with one key ingredient: the demand for safe dollar assets. The model matches patterns of dollar borrowing and currency mismatch, the U.S. external balance sheet, low U.S. interest rates and exorbitant privilege, spillovers of the U.S. monetary...

We relate the risk characteristics of currencies to measures of physical, cultural, and institutional distance. The currencies of countries which are more distant from other countries are more exposed to systematic currency risk. This is due to a gravity effect in the factor structure of...

Although the aggregate capital share of U.S. firms has increased, the firm-level capital share of a typical U.S. firm has decreased. This divergence is due to mega-firms that now produce a larger output share without a proportionate increase in labor compensation. We develop a model in which...

The convenience yield that foreign investors derive from holding U.S. Treasurys causes a failure of Covered Interest Rate Parity by driving a wedge between the yield on the foreign bonds and the currency-hedged yield on the U.S. Treasury bonds. Even before the 2007-2009 financial crisis, the...
