“…the relevant predictor for bilateral trade prices and volumes is not the bilateral exchange rate but the dollar exchange rate, even where the U.S. is on neither side of the trade transaction. A 1% U.S. dollar appreciation against all other currencies in the world predicts a 0.6–0.8% decline within a year in the volume of total trade between countries in the rest of the world, controlling for the global business cycle,” according to the 2017 IMF working paper entitled, ‘Global Trade and the Dollar’ from authors Emine Boz, Gita Gopinath and Mikkel Plagborg-Møller.
