US dollar

US dollar. The official currency of the United States and its territories, it is the most widely used currency in international transactions and a primary global reserve currency. Issued by the Federal Reserve System, it is subdivided into 100 cents and its symbol is $. The currency's status is underpinned by the size of the American economy, the stability of its political institutions, and its deep, liquid financial markets.

History

The dollar was adopted by the Congress of the Confederation with the Mint Act of 1792, establishing a bimetallic standard based on Spanish milled dollars and creating the United States Mint. The Civil War prompted the first issuance of federal paper money, known as United States Notes or "greenbacks." The Federal Reserve Act of 1913 created the Federal Reserve as the central banking system and authorized Federal Reserve Notes. A pivotal shift occurred in 1933 when President Franklin D. Roosevelt suspended the gold standard domestically, a move finalized internationally by the Bretton Woods Conference in 1944, which pegged global currencies to it and made it convertible to gold for foreign governments. President Richard Nixon ended this convertibility in 1971 during the Nixon shock, leading to the current system of floating exchange rates.

Design and denominations

Banknotes feature portraits of prominent American statesmen, including George Washington on the $1 bill, Abraham Lincoln on the $5, Alexander Hamilton on the $10, Andrew Jackson on the $20, Ulysses S. Grant on the $50, and Benjamin Franklin on the $100. The reverse sides depict national icons such as the Great Seal of the United States and buildings like the United States Treasury and Independence Hall. Coins include the Lincoln cent, Jefferson nickel, Roosevelt dime, Washington quarter, Kennedy half dollar, and Sacagawea dollar. Security features have evolved significantly, with recent series incorporating color-shifting ink, security threads, watermarks, and microprinting to combat counterfeiting.

Value and exchange rates

Its value relative to other currencies is determined by the foreign exchange market, influenced by factors such as interest rates set by the Federal Open Market Committee, inflation data from the Bureau of Labor Statistics, gross domestic product growth, and geopolitical events. Major exchange rates are tracked against currencies like the euro (EUR/USD), Japanese yen (USD/JPY), and British pound (GBP/USD). The U.S. Dollar Index (DXY) measures its strength against a basket of six major world currencies. Trade policies, actions by the International Monetary Fund, and interventions by foreign central banks like the People's Bank of China also significantly impact its valuation.

Role as international reserve currency

It dominates global reserves, comprising over 60% of allocated reserves reported to the International Monetary Fund. This status creates what is often called "exorbitant privilege," allowing the United States Treasury to finance deficits more easily. Most commodities, including crude oil, gold, and agricultural products, are priced in it on exchanges like the New York Mercantile Exchange. It is the primary currency for international debt issuance and is used in the vast majority of foreign exchange transactions, as reported by the Bank for International Settlements. Challenges to its hegemony are periodically discussed, involving potential rivals like the euro or initiatives such as BRICS currency cooperation, but its entrenched position in systems like SWIFT and global clearing networks remains largely unchallenged.

Production and circulation

Physical currency is produced by the Bureau of Engraving and Printing for notes and the United States Mint for coins, under the authority of the Department of the Treasury. The Federal Reserve Banks distribute currency and destroy unfit notes. Over $2.3 trillion is in circulation globally, with a significant portion held outside the United States in countries practicing dollarization like Ecuador and El Salvador, or as a stable store of value in regions with volatile local currencies. The lifecycle of a note is tracked by the FedCash Services, and anti-counterfeiting efforts are coordinated with agencies like the United States Secret Service and the Federal Bureau of Investigation.
