About US Dollar (USD)

What Is the United States Dollar (USD)?

The United States dollar (USD) is the official currency of the United States and several of its territories. It is represented by the symbol "$" and is subdivided into 100 cents. Banknotes are issued in denominations of $1, $2, $5, $10, $20, $50, and $100, while coins range from 1¢ to $1. Established by the Coinage Act of 1792, the dollar was originally linked to silver and gold, later solely to gold. In 1971, the U.S. abandoned the gold standard, and the dollar became a fiat currency, valued by government decree rather than physical commodities.

Why Is the USD Important?

The USD is the world's primary reserve currency and is widely used in international trade and finance. Many global commodities, such as oil and gold, are priced in dollars. Its dominance is supported by the size and stability of the U.S. economy and the liquidity of its financial markets. While the dollar experiences fluctuations due to economic and political events, it remains central to global finance and a key benchmark for international investment and trade.
