U.S. dollar (USD)

The United States dollar (ISO code: USD, symbol: $) is the official currency of the United States and several other nations, issued by the Federal Reserve. Established by the Coinage Act of 1792, it was based on the silver Spanish dollar and defined in terms of silver and gold weights. Subdivided into 100 cents, the US dollar became the principal global reserve currency following the 1944 Bretton Woods Agreement, continuing to anchor international trade.
