An exploration of the forward premium puzzle in currency markets

A standard empirical finding is that expected changes in exchangerates and interest rate differentials across countries are negativelyrelated, implying that uncovered interest rate parity is violatedin the data. This article provides new empirical evidence thatsuggests that violations of uncovered interest rate parity,and its economic implications, depend on the sign of the interestrate differential. A framework related to term structure modelsis developed to account for the puzzling relationship betweenexpected changes in exchange rates and interest rate differentials.Estimation results suggest that a particular term structuremodel can account for the puzzling empirical evidence.
