Original Sin and the Great Depression

Was foreign currency denominated debt a determinant of exchange rate and monetary policy during the Great Depression? Policy makers of the day thought so.

Multiple factors have been identified in the literature ranging from economic and political considerations to social preferences for monetary stability. We find that foreign currency debt and trade patterns, both shaped by history and geography, had a significant impact on these choices and hence on economic stability. The effect is likely to be about half as large as the output gap in determining exchange rate policy
