This paper analyzes daily covered interbank interest differentials for three emerging markets before and after the 1997/98 financial crises, and compares them with those of four developed economies. It examines descriptive statistics of covered differentials and the long‐run equilibrium (cointegrating) relationship between their interest rate and forward discount components. Mean differentials and their volatility were moderate before crises, but increased dramatically during crises. The main reasons are temporarily effective capital controls, large bank default risk premia, and capital market imperfections. The evidence for a cointegrating vector consistent with covered interest parity is strong, implying that, despite large short‐term deviations, covered interest parity does hold as an equilibrium relationship.
