We show that a global imbalance risk factor that captures the spread in countries' external imbalances and their propensity to issue external liabilities in foreign currency explains the cross-sectional variation in currency excess returns. The economic intuition is simple: net debtor countries...

We investigate the relation between foreign exchange (FX) order flow and the forward bias. We outline a decomposition of the forward bias according to which a negative correlation between interest rate differentials and order flow creates a time-varying risk premium consistent with that bias....

Carry trade strategies in which investors sell forward currencies that are at a forward premium and buy forward currencies that are at a forward discount are, on average, profitable. According to the uncovered interest rate parity they should not. A risk premia story might justify the high...

We propose an easy-to-implement conditional currency carry trade (CT) strategy that excludes regimes for which UIP is likely to hold, namely when interest rate differentials (IRDs) are very large during high foreign exchange (FX) volatility regimes. We find that conditioning a CT strategy on...

In this paper, we study the effectiveness of carry trade strategies during and after the financial crisis using a flexible approach to modeling currency returns. We decompose the currency returns into multiplicative sign and absolute return components, which exhibit much greater predictability...

We identify a global risk factor in the cross-section of implied volatility returns in currency markets. A zero-cost strategy that buys forward volatility agreements with downward sloping implied volatility curves and sells those with upward slopes - volatility carry strategy - generates...

I show that volatility risk of the dollar factor --- an equally weighted basket of developed U.S. dollar exchange rates --- carries a significant risk premium and that it is priced in the cross-section of currency volatility excess returns. The dollar factor volatility risk premium is negative...
