Precaution versus mercantilism: Reserve accumulation, capital controls, and the real exchange rate

Abstract

We document a new international stylized fact on the relationship between external wealth, capital controls, and the real exchange rate. We first re-confirm that the real exchange rate appreciates when external asset holdings increase, all else equal, a central mechanism in international economics. However, we find that increases in publicly held external assets (reserves) are associated with depreciation, especially if combined with high capital controls. Reserve accumulation is also associated with a larger trade surplus, and higher GDP and TFP growth, in countries with high capital controls. The results hold using an instrumental variable for reserves based on commodity export surrender requirements. A simple rationale is presented to account for the new fact: combined reserves and capital controls can affect trade balances via undervaluation (mercantilist motive), while reserve increases without controls can insure against crises (precautionary motive) independently of real exchange rates.
