Regressions of ex-post changes in floating exchange rates on appropriate interest differentials typically imply that the high interest rate currency tends to appreciate - the `forward discount puzzle'. Using data from the European Monetary System we find that a large part of the forward discount puzzle vanishes for regimes of fixed exchange rates. That is, deviations from uncovered interest parity appear to vary in a way that is dependent upon the exchange rate regime. By using the many EMS realignments we are also able to quantify the `peso problem'.
