Overview
The United States Dollar is the official currency of the United States of America. It is issued by the Federal Reserve System. The Dollar floats on foreign exchange markets and serves as the world's primary reserve currency, the de facto global money for international transactions, a store of value for global investors, and the foundation of international monetary systems.
Etymology & History
The word "Dollar" derives from the Dutch "daalder" via the Spanish "dólar." The United States Dollar was formally established in 1792, following American independence. The currency symbolized American sovereignty and monetary independence from British rule. Historically backed by gold until 1933 (circulating coins) and 1971 (Bretton Woods system dissolution), the Dollar transitioned to fiat currency and maintained global dominance through institutional strength.
United States' monetary history includes colonial currencies, early American dollars (1792–), the gold standard era (1900–1933 circulating coins, 1944–1971 for reserves), and modern fiat dollar dominance (1971–present).
