A common anchor for exchange rates
At the 1944 Bretton Woods conference, delegates from 44 Allied countries sought to avoid a repeat of the monetary turmoil between the world wars. Governments had devalued currencies, imposed restrictions on payments, and struggled to keep trade moving. When exchange rates swung unpredictably, businesses faced greater risk in setting prices and paying for goods across borders.
The plan gave currencies a shared reference point: the U.S. dollar. Participating countries set official exchange rates against it and generally tried to keep their currencies within narrow limits. The United States, in turn, promised to exchange dollars held by foreign monetary authorities for gold at a fixed price. This was not a system in which every person could freely trade currency for gold; it was a framework for managing international payments.
The institutions behind the rules
Fixed rates could make trade more predictable, but they also limited a government’s freedom to respond when its economy came under pressure. The system allowed countries to adjust their exchange rates in certain circumstances, while the International Monetary Fund (IMF) was created to support countries facing payment problems and help oversee the rules. The World Bank, initially focused on postwar reconstruction, was established alongside it.
The arrangement reflected the postwar balance of economic power: the United States held a central role, and the dollar became the main currency used in international finance. That made the system workable, but also made it dependent on confidence in the dollar and the U.S. promise to exchange official dollar holdings for gold.
A framework that changed
As dollars accumulated abroad, doubts grew about whether the United States could maintain that gold promise. In 1971, it ended dollar convertibility into gold for foreign monetary authorities, and the fixed-rate system eventually gave way to more flexible exchange rates. Its original rules did not last, but the institutions and the dollar’s central place in global finance did—an enduring consequence of a system built to make cross-border payments more predictable.
