The IMF invests significant resources in developing models to estimate equilibrium exchange rates. This column assesses the predictive power of one vintage of IMF exchange rate models during 2006–2011. The models performed exceptionally well at predicting exchange rate movements over the medium run, which is particularly remarkable given that the period covered the unanticipated Global Crisis and the assessments were not shared publicly at the time.

The returns are generated primarily by spot exchange rate returns, rather than interest differentials. The strategy’s performance can be explained by speculator-hedger interactions in the currency market in the presence of time-varying capital constraints on speculators.
