Bretton Woods System

The Bretton Woods system of monetary management established the rules for commercial and financial relations among the world's major industrial states in the mid-20th century. The Bretton Woods system was the first example of a fully negotiated monetary order intended to govern monetary relations among independent nation-states.

Preparing to rebuild the international economic system as World War II was still raging, 730 delegates from all 44 Allied nations gathered at the Mount Washington Hotel in Bretton Woods, New Hampshire, United States, for the United Nations Monetary and Financial Conference. The delegates deliberated during 1–22 July 1944, and signed the Agreement on its final day.

Setting up a system of rules, institutions, and procedures to regulate the international monetary system, the planners at Bretton Woods established the International Monetary Fund (IMF) and the International Bank for Reconstruction and Development (IBRD), which today is part of the World Bank Group. These organizations became operational in 1945 after a sufficient number of countries had ratified the agreement.

The chief features of the Bretton Woods system were an obligation for each country to adopt a monetary policy that maintained the exchange rate by tying its currency to the U.S. dollar and the ability of the IMF to bridge temporary imbalances of payments.

On 15 August 1971, the United States unilaterally terminated convertibility of the US$ to gold. This brought the Bretton Woods system to an end and saw the dollar become fiat currency. This action, referred to as the Nixon shock, created the situation in which the United States dollar became a reserve currency used by many states. At the same time, many fixed currencies (such as GBP, for example), also became free floating.
