BRETTON WOODS, New Hampshire, October 4 — The 1944 Bretton Woods Agreement created the IMF and World Bank, pegged currencies to the U.S. dollar convertible at $35 per ounce of gold, and required members to maintain exchange rates within ±1% of par. The conference, officially the United Nations Monetary and Financial Conference, ran from July 1 to July 22, 1944, at the Mount Washington Hotel and was attended by 44 Allied nations.
It aimed to design a new international monetary system after the economic instability of the 1930s and World War II disruptions. The agreement established the International Monetary Fund to oversee exchange rate stability and provide short-term financial assistance for balance-of-payments difficulties, and the International Bank for Reconstruction and Development — now part of the World Bank Group — to provide long-term loans for postwar reconstruction and development.
Under the Bretton Woods system, currencies were pegged to the U.S. dollar, which was convertible to gold at a fixed rate of $35 per ounce, making the dollar the world’s primary reserve currency. Member countries had to maintain their currency values within narrow bands of ±1% around the pegged rate, with adjustments allowed only in cases of ‘fundamental disequilibrium’ and subject to IMF approval. The agreement also included provisions for capital controls to prevent speculative flows and promote domestic policy autonomy.
The system facilitated unprecedented growth in international trade and investment during the postwar boom, with global exports growing at an average annual rate of over 8% between 1950 and 1970. The Bretton Woods framework began to unravel in the late 1960s due to growing U.S. inflation, rising trade deficits, and declining gold reserves, culminating in President Richard Nixon’s announcement on August 15, 1971, that the United States would suspend the dollar’s convertibility into gold — an action known as the Nixon Shock.
This effectively ended the fixed exchange rate system and led to the transition to floating exchange rates by the mid-1970s. Despite the collapse of the gold peg, the IMF and World Bank endured and evolved, expanding their membership to include nearly all countries and adapting their roles to address debt crises, structural adjustment, and global financial stability. Today, the IMF has 190 member countries and provides surveillance, lending, and technical assistance, while the World Bank Group comprises five institutions focused on poverty reduction and sustainable development.
The Bretton Woods Agreement remains a foundational reference in international economics, shaping modern discussions on exchange rate regimes, global financial governance, and the role of multilateral institutions in managing economic interdependence. Looking ahead, policymakers will continue to assess the relevance of Bretton Woods-era institutions in addressing 21st-century financial challenges, including climate financing, digital currencies, and rising debt levels in emerging markets. The durability of its core institutions suggests ongoing influence, even as the original fixed exchange rate system no longer exists.
