We study the properties of the carry trade, a currency speculation strategy in which an investor borrows low-interest-rate currencies and lends high-interest-rate currencies. This strategy generates payoffs which are on average large and uncorrelated with traditional risk factors. We argue that...

The carry trade strategy involves selling forward currencies that are at a forward premium and buying forward currencies that are at a forward discount. We compare the payoffs to the carry trade applied to two different portfolios. The first portfolio consists exclusively of developed country...

Currencies that are at a forward premium tend to depreciate. This 'forward-premium puzzle' represents an egregious deviation from uncovered interest parity. We document the properties of returns to currency speculation strategies that exploit this anomaly. We show that these strategies yield...

Exchange-rate models fit very well for the U.S. dollar in the 21st century. A "standard" model that includes real interest rates and a measure of expected inflation for the U.S. and the foreign country, the U.S. comprehensive trade balance, and measures of global risk and liquidity demand is...

Foreign investors' changing appetite for risk-taking have been shown to be a key determinant of the global financial cycle. Such fluctuations in risk sentiment also correlate with the dynamics of UIP premia, capital flows, and exchange rates. To understand how these risk sentiment changes...

We review the literature on multi-horizon currency risk premiums. We show how the multi-horizon implications arise from the classic present-value relationship. We further show how these implications manifest themselves in the interaction between bond and currency risk premiums. This link is...

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...

Recent theories of exchange rate determination have emphasized limited UIP arbitrage by international financial institutions. New regulations since 2008 have also lead to imperfect CIP arbitrage. We show that under limited CIP arbitrage the exchange rate and CIP deviation are jointly determined...
