What Is Forex (Foreign Exchange)?

Forex, short for foreign exchange and often abbreviated as FX, is the global marketplace where participants buy, sell, and exchange currencies. It is the largest and most liquid financial market in the world, with an average daily trading volume of about $7.5 trillion as of 2022.
Key Takeaways
- Forex (foreign exchange) is the global, decentralized market for trading currencies in pairs.
- It is the largest and most liquid financial market, operating 24/5 across major financial centers.
- Currency prices fluctuate based on economic, political, and market factors.
- Forex trading involves buying one currency while selling another, with no physical exchange of money.
- The market offers opportunities for speculation, hedging, and international business transactions but carries risks related to volatility and leverage.
How Forex Works
Forex trading involves the simultaneous buying of one currency and selling of another, always quoted in pairs (e.g., EUR/USD, GBP/JPY). The price of a currency pair reflects how much of the quoted currency (second currency) is needed to buy one unit of the base currency (first currency). For example, if EUR/USD is 1.10, it means 1 euro costs 1.10 U.S. dollars.
Unlike stock markets, the forex market is decentralized and operates over-the-counter (OTC) through electronic networks connecting banks, brokers, institutions, and individual traders worldwide. It runs 24 hours a day, five days a week, opening Sunday evening and closing Friday evening (ET), covering major financial centers like London, New York, Tokyo, and Singapore.
