Bretton Woods Agreement in the context of "World Bank Group"

The United States dollar (symbol: $; currency code: USD) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color.

The U.S. dollar was originally defined under a bimetallic standard of 371.25 grains (24.057 g) (0.7734375 troy ounces) fine silver or, from 1834, 23.22 grains (1.505 g) fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its equivalence to gold was revised to $35 per troy ounce. In 1971 all links to gold were repealed. The U.S. dollar became an important international reserve currency after the First World War, and displaced the pound sterling as the world's primary reserve currency by the Bretton Woods Agreement towards the end of the Second World War. The dollar is the most widely used currency in international transactions, and a free-floating currency. It is also the official currency in several countries and the de facto currency in many others, with Federal Reserve Notes (and, in a few cases, U.S. coins) used in circulation.

The United States dollar was established as the world's foremost reserve currency by the Bretton Woods Agreement of 1944. It claimed this status from sterling after the devastation of two world wars and the massive spending of the United Kingdom's gold reserves. Despite all links to gold being severed in 1971, the dollar continues to be the world's foremost reserve currency. Furthermore, the Bretton Woods Agreement also set up the global post-war monetary system by setting up rules, institutions and procedures for conducting international trade and accessing the global capital markets using the U.S. dollar.

The U.S. dollar is widely held by central banks, foreign companies and private individuals worldwide, in the form of eurodollar foreign deposit accounts (not to be confused with the euro), as well as in the form of US$100 notes, an estimated 75% of which are held overseas. The U.S. dollar is predominantly the standard currency unit in which goods are quoted and traded, and with which payments are settled in, in the global commodity markets.
