Foreign Exchange (Forex)

Last verified 5 Nov 2025·How we review

Foreign Exchange (Forex) refers to the global marketplace where currencies are traded. It is the largest financial market in the world, with a vast daily trading volume that surpasses the combined volume of all the world’s stock markets.

What it means

Forex trading involves the buying and selling of currencies against each other as exchange rate pairs. Participants in this market include governments, central banks, commercial banks, other institutional investors, and individual traders. The primary purpose of forex trading is to facilitate international trade and investment by allowing businesses to convert one currency to another. Investors also participate in forex trading to speculate on the movements of currencies and hedge against potential losses.

Why it matters

• Global Trade: Forex is essential for supporting global trade. Businesses need to exchange currencies to import or export goods and services.
• Investment Diversification: Forex trading offers investors an opportunity to diversify their portfolios beyond traditional equity and fixed-income investments.
• Currency Speculation: Forex markets provide a platform for speculating on currency movements, enabling traders to profit from currency volatility.
• Hedge Against Risk: Companies and investors use forex markets to hedge against potential losses caused by fluctuations in currency exchange rates.

How it works

Forex trading operates 24 hours a day in different parts of the world, from when the Sydney market opens on Monday morning to when the New York market closes on Friday evening. Currency pairs are quoted in terms of one currency against another. The first currency in the pair is the base currency, and the second is the quote currency. For example, in the EUR/USD currency pair, EUR is the base currency, and USD is the quote currency.

Common Use Cases or Examples

• Importers and Exporters: Businesses importing or exporting goods and services need to exchange their home currency for foreign currency.
• Forex Traders: Individual and institutional investors trade currency pairs to speculate on the rise or fall of one currency against another.
• Central Banks and Governments: Use forex transactions to manage their country’s currency value and reserves.
• Tourists or Overseas Travelers: Exchange their home currency for the currency of the country they are visiting.
