The Organisation for European Economic Co-operation Is Founded (1948)
On April 16, 1948, representatives of sixteen Western European nations signed a convention in Paris establishing the Organisation for European Economic Co-operation, or OEEC. Created to coordinate the distribution of American Marshall Plan aid and rebuild a continent devastated by World War II, the OEEC became the direct institutional ancestor of today's Organisation for Economic Co-operation and Development. Its founding marked one of the first major steps toward postwar European economic cooperation and integration.
Rebuilding a Shattered Continent
By 1948, Europe lay in economic ruin. Three years after the end of World War II, industrial output across much of the continent remained far below prewar levels, currencies were unstable, and food and fuel shortages were widespread. In response, U.S. Secretary of State George Marshall had proposed in June 1947 a massive American aid program to help rebuild European economies and stave off the political instability that many feared would open the door to communist influence. The United States insisted, however, that European nations themselves organize the effective distribution of this assistance rather than negotiate aid on a purely bilateral basis. This condition prompted representatives from sixteen countries—including the United Kingdom, France, Italy, the Benelux nations, and the Scandinavian states—to gather in Paris and draft a framework for joint economic planning. The result was the Convention for European Economic Co-operation, signed on April 16, 1948, which formally established the OEEC as the administrative body charged with allocating roughly $13 billion in Marshall Plan funds among its members over the following years.
Did You Know?
The OEEC's Paris headquarters, the Château de la Muette, remains the OECD's home today—meaning the organization has occupied the same building for well over 75 years, even as its membership grew from 16 founding European states to 38 countries spanning the globe.
Coordinating Marshall Plan Aid
The OEEC's first and most urgent task was managing the flow of American assistance under the European Recovery Program. Rather than allowing each country to compete independently for funds, the organization required member states to submit coordinated national recovery plans, encouraging cooperation over rivalry. This arrangement pushed European governments to share economic data, negotiate trade barriers downward, and gradually restore currency convertibility—steps that would have been far harder to achieve through purely national efforts. Headquartered in Paris, the OEEC also worked to liberalize intra-European trade and payments, helping to dismantle the tangle of wartime and postwar restrictions that had strangled commerce. By the mid-1950s, as Marshall Plan funding wound down, the OEEC had already proven its value as a permanent forum for economic dialogue, laying practical groundwork for later European institutions such as the European Coal and Steel Community and, eventually, the European Economic Community.
From OEEC to OECD
As European economies recovered through the late 1950s and transatlantic economic relationships deepened, the original mission of distributing American aid became obsolete, but the value of a standing forum for economic cooperation did not. In December 1960, member nations, along with the United States and Canada, signed a new convention transforming the organization into the Organisation for Economic Co-operation and Development, which formally came into being on September 30, 1961. The renamed OECD broadened its scope beyond European reconstruction to promote economic growth, expand world trade, and raise living standards among industrialized democracies worldwide. Over subsequent decades, the OECD grew from its original membership to 38 countries, incorporating nations from Asia, Latin America, and the Pacific alongside its European and North American founders. Today it functions as a leading forum for policy analysis, statistical research, and international coordination on issues ranging from taxation to education, carrying forward the spirit of cooperative problem-solving first established in Paris in 1948.
