We explore the role of interest rate policy in the exchange rate determination process. Specifically, we derive exchange rate equations from interest rate rules that are theoretically optimal under a few alternative settings. The exchange rate equation depends on its underlying interest rule and its performance could vary across evaluation criteria and sample periods. The exchange rate equation implied by the interest rate rule that allows for interest rate and inflation inertia under commitment offers some encouraging results — exchange rate changes “calibrated” from the equation have a positive and significant correlation with actual data, and offer good direction of change prediction. Our exercise also demonstrates the role of the foreign exchange risk premium in determining exchange rates and the difficulty of explaining exchange rate variability using only policy based fundamentals.
► Roles of interest rate policy in modeling exchange rate dynamics. ► The specification of an optimal interest rate rule varies with model structure. ► Performance of exchange rate equation depends on the underlying interest rate rule. ► The performance also varies across evaluation criteria and sample periods. ► Difficult to model exchange rates using only economic fundamentals.
