When a country’s currency depreciates, its export volumes are expected to increase. Yet some recent episodes suggest that exports now barely respond to significant exchange rate movements. This column argues that global value chains are an important part of the answer, as countries now need to import to export, and often re-import their exports. To assess the consequences of international input-output linkages on exchange rate elasticities, policymakers need indices of global value chain participation based on currencies rather than countries.
