The Causal Effect of the Dollar on Trade

Abstract

This paper establishes a causal link between the dollar exchange rate and international trade flows, employing a new instrument for the U.S. dollar that is based on domestic U.S. housing activity. In line with the dominant currency paradigm (Gopinath et al. (2020)), import prices and quantities respond strongly to a country’s exchange rate with the U.S. dollar. Once we instrument the dollar, we find evidence for perfect passthrough of the dollar exchange rate to import prices that are invoiced in dollars. A dollar appreciation of 1 percent lowers import quantities by 1.5 percent for countries that fully invoice in dollars.
