The IMF was conceived in July 1944, when representatives of 45 countries meeting in the town of Bretton Woods, New Hampshire, in the northeastern United States, agreed on a framework for international economic cooperation, to be established after the Second World War. They believed that such a framework was necessary to avoid a repetition of the disastrous economic policies that had contributed to the Great Depression.
The IMF came into formal existence in December 1945, when its first 29 member countries signed its Articles of Agreement. It began operations on March 1, 1947. Later that year, France became the first country to borrow from the IMF.
The IMF's membership began to expand in the late 1950s and during the 1960s as many African countries became independent and applied for membership. But the Cold War limited the Fund's membership, with most countries in the Soviet sphere of influence not joining.
Par value system
The countries that joined the IMF between 1945 and 1971 agreed to keep their exchange rates (the value of their currencies in terms of the U.S. dollar and, in the case of the United States, the value of the dollar in terms of gold) pegged at rates that could be adjusted only to correct a "fundamental disequilibrium" in the balance of payments, and only with the IMF's agreement. This par value system?also known as the Bretton Woods system?prevailed until 1971, when the U.S. government suspended the convertibility of the dollar (and dollar reserves held by other governments) into gold.
The end of the Bretton Woods System (1972?81)
By the early 1960s, the U.S. dollar's fixed value against gold, under the Bretton Woods system of fixed exchange rates, was seen as overvalued. A sizable increase in domestic spending on President Lyndon Johnson's Great Society programs and a rise in military spending caused by the Vietnam War gradually worsened the overvaluation of the dollar.
End of Bretton Woods system
The system dissolved between 1968 and 1973. In August 1971, U.S. President Richard Nixon announced the "temporary" suspension of the dollar's convertibility into gold. While the dollar had struggled throughout most of the 1960s within the parity established at Bretton Woods, this crisis marked the breakdown of the system. An attempt to revive the fixed exchange rates failed, and by March 1973 the major currencies began to float against each other.
Since the collapse of the Bretton Woods system, IMF members have been free to choose any form of exchange arrangement they wish (except pegging their currency to gold): allowing the currency to float freely, pegging it to another currency or a basket of currencies, adopting the currency of another country, participating in a currency bloc, or forming part of a monetary union.
Oil shocks
Many feared that the collapse of the Bretton Woods system would bring the period of rapid growth to an end. In fact, the transition to floating exchange rates was relatively smooth, and it was certainly timely: flexible exchange rates made it easier for economies to adjust to more expensive oil, when the price suddenly started going up in October 1973. Floating rates have facilitated adjustments to external shocks ever since.
The IMF responded to the challenges created by the oil price shocks of the 1970s by adapting its lending instruments. To help oil importers deal with anticipated current account deficits and inflation in the face of higher oil prices, it set up the first of two oil facilities.
