Can risk explain the profitability of technical trading in currency markets?
Academic studies show that technical trading rules would have earned substantial excess returns over long periods in foreign exchange markets. However, the approach to risk adjustment has typically been rather cursory. We examine the ability of a wide range of models: CAPM, quadratic CAPM, downside risk CAPM, Carhart’s 4-factor model, the C-CAPM, an extended C-CAPM with durable consumption, Lustig-Verdelhan (LV) carry-trade factor model, and models including macroeconomic factors, and foreign exchange volatility, skewness and liquidity, to explain these technical trading returns. No model ...

Oil Prices, Exchange Rates and Interest Rates
There has been much interest in the relationship between the price of crude oil, the value of the U.S. dollar, and the U.S. interest rate since the 1980s. For example, the sustained surge in the real price of oil in the 2000s is often attributed to the declining real value of the U.S. dollar as well as low U.S. real interest rates, along with a surge in global real economic activity. Quantifying these effects one at a time is difficult not only because of the close relationship between the interest rate and the exchange rate, but also because demand and supply shocks in the oil market in turn ...

Foreign exchange predictability during the financial crisis: implications for carry trade profitability
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 than raw returns. We allow the two components to respond to currency-specific risk factors and use the joint conditional distribution of these components to obtain forecasts of future carry trade returns. Our results suggest that the decomposition model produces higher forecast and directional accuracy ...

US Equity Tail Risk and Currency Risk Premia
We find that a US equity tail risk factor constructed from out-of-the-money S&P 500 put option prices explains the cross-sectional variation of currency excess returns. Currencies highly exposed to this factor offer a low currency risk premium because they appreciate when US tail risk increases. In a reduced-form model, we show that country-specific tail risk factors are priced in the cross section of currency returns only if they contain a global risk component. Motivated by the intuition from the model and by our empirical results, we construct a novel proxy for a global tail risk factor by ...
