Yet, whether they are used in combination remains an open question. Thanks to a rich dataset from 1950, we investigate how the response of FX reserves to an exogenous US monetary shock depends on capital controls. The response is insignificant with a very close capital account. By contrast, for a significant number of countries, FX reserves and capital controls are combined to tame the effects of an international financial shock. Yet, as countries open up financially, FX reserves replace capital controls. There is no one-sizes-fits-all recipe. 收起
