Bretton Woods Agreement

The Bretton Woods Agreement, negotiated in July 1944 at a conference in New Hampshire, established the institutional and monetary framework for the postwar world. Under Bretton Woods, the US dollar was pegged to gold at $35 per ounce, and all other currencies were pegged to the dollar. It was an attempt to combine the discipline of the gold standard with enough flexibility to avoid the rigidity that had worsened the Great Depression.

The postwar context and the design

In 1944, World War II was drawing to a close. American and British policymakers saw an opportunity to design a stable international monetary system for the postwar era. The old gold standard had been rigid and deflationary — countries could not expand their money supplies without losing gold. This rigidity had worsened the Great Depression. But pure floating rates, in which exchange rates moved freely, would create uncertainty and disrupt trade.

Bretton Woods was a compromise: currencies would be fixed to one another through the dollar, and the dollar would be fixed to gold. This provided stability without the complete rigidity of the classical gold standard. If a country needed to devalue its currency to boost exports or manage inflation, it could do so with IMF consent. This flexibility was crucial.

The IMF was created to lend to countries facing temporary balance-of-payments difficulties, to tide them over while they adjusted. The World Bank (formally the International Bank for Reconstruction and Development) was created to finance development and reconstruction.

The postwar order and American dominance

Bretton Woods worked well for the first 20 years. The US, having emerged from the war with its industrial base intact and most of the world’s gold, was the dominant financial power. The dollar became “as good as gold.” American exports were cheap, and the US ran trade surpluses, so the dollar was in demand. Countries were willing to hold dollar reserves and peg their currencies to it.

The system provided stability. Businesses could sign long-term contracts without fear of wild currency swings. Trade grew. The “Golden Age of Capitalism” — the 1950s and 1960s — saw rapid growth in the developed world, enabled in part by the stability Bretton Woods provided.

The growing contradictions

But Bretton Woods contained a fatal contradiction, identified by economist Robert Triffin: the dollar was both a reserve currency (held by other countries) and the currency of a nation with its own economic interests. As the US ran persistent trade deficits from the mid-1960s onward, dollars accumulated overseas. Foreign governments began to worry that the US did not have enough gold to back all the dollars in circulation at the promised rate of $35 per ounce.

The fear was not irrational. By the early 1970s, the US gold reserve, once dominant, had been depleted as other countries and private investors converted dollars into gold. The US faced a choice: either devalue the dollar (reducing its gold price from $35 per ounce) or break the link between the dollar and gold altogether.

The collapse

In August 1971, President Richard Nixon chose the latter course. He “closed the gold window” — the US would no longer redeem dollars for gold at a fixed rate. This announcement, called the Nixon Shock, was the de facto end of Bretton Woods. Within a year, the major currencies were floating against one another.

The collapse did not happen overnight; there was an attempt to maintain fixed rates at a new parity (the Smithsonian Agreement of 1971), but within 14 months, major currencies were floating freely. Bretton Woods was dead.

Legacy: The institutions survive, the rates do not

The IMF and World Bank, created by the Bretton Woods Agreement, survived its monetary collapse and continue to operate today, though with much-expanded mandates. The Bretton Woods system itself — fixed exchange rates backed by gold — is seen as a historical artifact, abandoned because of the contradictions embedded in its design.

The collapse of Bretton Woods and the shift to floating exchange rates that followed did not prevent crises — indeed, the 1970s and 1980s saw numerous currency crises and debt crises. But it did provide flexibility that the gold standard had lacked. The ability to adjust exchange rates, while sometimes disruptive, allowed countries to manage inflation and employment in ways Bretton Woods would not have permitted.
