United States dollar (symbol: $; code: USD; also abbreviated US$), often referred to as the dollar, is the official currency of the United States and its territories per the Coinage Act of 1792. The dollar is divided into 100 smaller cent (¢) units, but is occasionally divided into 1000 mills (₥) for accounting. The issuance of the currency is controlled by the Federal Reserve System, which acts as the nation's central bank.

History

The history of the United States dollar dates back to the early days of the United States. The Continental Congress of the United States authorized the issuance of the Continental Currency in 1775 to fund the Revolutionary War. However, due to lack of backing and massive counterfeiting, the Continental Currency depreciated rapidly, leading to the phrase "not worth a Continental." This experience underlined the need for a stable and secure currency.

The Coinage Act of 1792 introduced the United States dollar as the country's standard unit of money. The Act created the United States Mint and established a fixed rate of exchange with foreign currencies. The dollar was based on the Spanish dollar, which was popular in trade throughout the Americas.

Design

The design of the United States dollar has undergone several changes over the years. The current designs, known as the Federal Reserve Note, feature portraits of famous American statesmen on the obverse and iconic symbols of American freedom and history on the reverse. The $1 bill features George Washington, the $2 bill features Thomas Jefferson, the $5 bill features Abraham Lincoln, the $10 bill features Alexander Hamilton, the $20 bill features Andrew Jackson, the $50 bill features Ulysses S. Grant, and the $100 bill features Benjamin Franklin.

Circulation

The United States dollar is the most widely used currency in international transactions and is one of the world's dominant reserve currencies. It is also the official currency in several other countries and territories outside the United States, a practice known as dollarization. The widespread use of the dollar is a reflection of the size and strength of the U.S. economy and the nation's pivotal role in the global financial system.

Monetary Policy

The Federal Reserve System (the Fed) is responsible for the monetary policy of the United States and uses various tools to control the supply of money to ensure economic stability. The Fed's main objectives are to promote maximum employment, stable prices, and moderate long-term interest rates.

Exchange Rates

The value of the United States dollar can fluctuate based on a variety of factors including inflation rates, interest rates, and the balance of trade. The exchange rates between the dollar and other currencies are determined in the foreign exchange market.

Legal Tender

The United States dollar is legal tender for all debts, public and private, within the United States. The phrase "This note is legal tender for all debts, public and private" is printed on all Federal Reserve Notes.

Challenges and Criticisms

Despite its status, the dollar faces challenges such as inflation, national debt, and concerns over its future as the world's primary reserve currency. Critics argue that these issues could undermine the dollar's value and stability over time.
