We explore the consequences of global capital market segmentation by currency for the optimal currency composition of borrowing by firms. Global bond portfolios are driven by the currency of denomination of assets as investors prefer to lend in their home currency or the international currency,...

We study the effects of dollar swap lines using high frequency responses in asset prices around policy announcements. News about expanded dollar swap lines causes a reduction in liquidity premia, compression of deviations from covered interest parity (CIP), and depreciation of the dollar. Equity...

Since 2007, an increase in risk or risk aversion has resulted in a US dollar appreciation and greater deviations from covered interest parity (CIP). In contrast, prior to 2007, risk had no impact on the dollar, and CIP held. To explain these phenomena, we develop a two-country model featuring...

We introduce safe asset demand for dollar-denominated bonds into a tractable incomplete-market model of exchange rates. The convenience yield on dollar bonds enters as a stochastic wedge in the Euler equations for exchange rate determination. This wedge reduces the pass-through from marginal...

The failure of uncovered interest rate parity to explain short-term interest rate movements is well documented. We show that short-term changes in long-term interest rates do help to explain short-term exchange rate movements. The relationship gets stronger over our sample period, as the...
