We assess the relationship between monetary policy, foreign exchange risk premia and term premia at the zero lower bound. We estimate a structural VAR including U.S. and foreign interest rates and exchange rates, and identify monetary policy shocks through a method that uses these surprises as the crucial "external instrument" that achieves identification without having to use implausible short-run restrictions. This allows us to measure effects of policy shocks on expectations, and hence risk premia. U.S. monetary policy easing shocks lower domestic and foreign bond risk premia, lead to dollar depreciation and lower foreign exchange risk premia. We present some evidence that U.S. monetary policy easing surprises at the ZLB shift options-implied skewness in the direction of dollar depreciation and also reduce the demand for the liquidity of short-term U.S. Treasuries. Both of these channels should lower foreign exchange risk premia.
