The National and Regional Economic Warfare During the 1930s Precipitated World War II

Since only the United States remained on even a partial gold standard, while other countries moved to purely fiat standards, gold began to flow heavily into the United States, an inflow accelerated by the looming war conditions in Europe. The collapse of the shaky and inflationary British-created gold exchange standard during the depression led to a dangerous world of competing and conflicting national currencies and protectionist blocs. Each nation attempted to subsidize exports and restrict imports through competing tariffs, quotas, and currency devaluations.

The pervasive national and regional economic warfare during the 1930s played a major though neglected role in precipitating World War II. After the war was over, Secretary of State Cordell Hull made the revealing comment that

war did not break out between the United States and any country with which we had been able to negotiate a trade agreement. It is also a fact that, with very few exceptions, the countries with which we signed trade agreements joined together in resisting the Axis. The political lineup follows the economic lineup.

A primary war aim for the United States in World War II was to reconstruct the international monetary system from the conflicting currency blocs of the 1930s into a new form of international gold exchange standard. This new form of gold exchange standard, established at an international conference at Bretton Woods in 1944 by means of great American pressure, closely resembled the ill-fated British system of the 1920s. The difference is that world fiat currencies now pyramided on top of dollar reserves kept in New York instead of sterling reserves kept in London; once again, only the base country, in this case the U.S., continued to redeem its currency in gold.
