The Smithsonian Agreement, announced in December 1971, created a new dollar standard, whereby the currencies of a number of industrialized states were pegged to the US dollar. These currencies were allowed to fluctuate by 2.25% against the dollar.

This agreement was  negotiated in 1971 among the ten leading developed nations in the world, namely Belgium, Canada, France, Germany, Italy, Japan, the Netherlands, Sweden, the United Kingdom, and the United States.

On December 17 and 18 1971, representatives of the Group of Ten leading developed nations met at the Smithsonian Institution in Washington, D.C., and agreed on a realignment of currencies and a new set of pegged exchange rates. The dollar was devalued in terms of gold, while other currencies were appreciated in terms of the dollar. On the whole, the dollar was devalued by nearly 10 percent in relation to the other Group of Ten currencies (those of the United Kingdom, Canada, France, West Germany, Italy, the Netherlands, Belgium, Sweden, and Japan). Several months after the Smithsonian Agreement, the six members of the European Economic Community (EEC) agreed to maintain their exchange rates within a range of 2.25 percent of parity with each other.

The Smithsonian Agreement proved to be only a temporary solution to the international currency crisis. A second devaluation of the dollar (by 10 percent) was announced in February 1973, and not long afterward Japan and the EEC countries decided to let their currencies float. At the time, these were thought of as temporary measures to cope with speculation and capital shifts; it was, however, the end of the system of established par values.
