High short-term interest rates predict domestic currency appreciation and low excess returns for long-term bonds. These facts are at odds with two textbook conditions describing the relationship between different maturity interest rates and exchange rates: uncovered interest parity (UIP) and the expectations hypothesis. This column explains that both conditions can be reconciled with the data if agents are assumed to have sticky rather than perfectly rational expectations concerning short rates. It also demonstrates how this empirically motivated change in model assumptions has broad implications for interpreting the effects of monetary policy on exchange rates and yield curves.
