Forex (short for foreign exchange) is the world’s largest and most liquid financial market, where banks, corporations, investment funds, governments, and individual traders buy and sell currencies. Unlike stock exchanges, Forex operates over-the-counter (OTC) — meaning transactions occur directly between participants via electronic trading platforms, not on a centralized exchange. According to the Bank for International Settlements, the global foreign exchange market’s average daily turnover reached $9.6 trillion in April 2025.

Why Does the Currency Market Exist?
The global economy depends on currency conversion. A European importer buying goods from the U.S. needs dollars. An American company paying salaries to employees in Europe needs euros. An investment fund purchasing foreign stocks or bonds must convert capital into the target currency.
The foreign exchange market serves several core functions:
- Enabling international payments
- Facilitating cross-border trade and services
- Allowing investors to allocate capital across global assets
- Providing tools to hedge against currency risk
- Supporting speculative trading
An exchange rate expresses how many units of one currency are needed to buy one unit of another. For example, the EUR/USD quote of 1.1000 means one euro equals 1.10 U.S. dollars. The European Central Bank defines the exchange rate precisely as the ratio at which one currency is exchanged for another.
How Currency Pairs Work
In Forex, currencies are always traded in pairs. Quotes reflect the value of the first (base) currency relative to the second (quote) currency:
- EUR/USD — euro vs. U.S. dollar
- GBP/USD — British pound vs. U.S. dollar
- USD/JPY — U.S. dollar vs. Japanese yen
- EUR/GBP — euro vs. British pound
In EUR/USD, the euro is the base currency; the U.S. dollar is the quote currency.
If a trader expects the euro to strengthen against the dollar, they buy EUR/USD — opening a long position. If they expect the euro to weaken, they sell the pair — opening a short position.
For instance, if EUR/USD rises from 1.1000 to 1.1100, the euro has appreciated by one U.S. cent — roughly 0.91% — against the initial level. The buyer profits; the seller incurs a loss (excluding fees and financing costs).
Bid Price, Ask Price, and Spread
Each currency pair has two simultaneous prices:
- Bid — the price at which the broker buys the base currency from you.
- Ask — the price at which the broker sells the base currency to you.
The difference between them is the spread, a primary transaction cost.
For example, if EUR/USD is quoted at 1.1000/1.1002, you can sell euros at 1.1000 and buy them at 1.1002. The spread is two pips (the smallest quoted increment).
Spread size depends on pair liquidity, time of day, market volatility, and broker terms. Major pairs typically have narrower spreads than emerging-market currencies. Spreads often widen sharply during major news releases or high-volatility events.
Who Participates in Forex Trading?
Large financial institutions form the backbone of the Forex market, executing trades for clients, managing proprietary positions, and providing liquidity.
- Central banks manage foreign reserves, implement monetary policy, and occasionally intervene in markets to smooth excessive exchange rate swings or support economic goals.
- Commercial and investment banks process international payments, trade with each other, and provide quotes to other market participants.
- Multinational corporations buy foreign currency for imports, payroll, taxes, and services — and hedge against adverse exchange rate moves.
- Investment and pension funds convert capital when investing abroad and use FX instruments to manage currency exposure.
- Hedge funds and professional traders seek profit from exchange rate movements, interest rate differentials, and arbitrage opportunities across related markets.
- Retail traders access the market through brokers and dealers. Their share of total volume is significantly smaller than that of banks and institutional investors.
Why Exchange Rates Change
Currency values are driven by supply and demand, shaped simultaneously by economic, financial, and geopolitical factors.
Central bank policy rates are among the most influential drivers. Higher yields in a given currency tend to attract investor capital.
Markets react not only to actual decisions but also to expectations. A currency may strengthen well before a rate hike if investors anticipate it — and sometimes weaken afterward, as the event has already been priced in.
Inflation
Persistent high inflation erodes purchasing power and may prompt central banks to tighten policy. The market’s reaction depends on whether participants prioritize the deteriorating economic outlook or the likelihood of higher rates.
Economic growth
Strong fundamentals — such as GDP, industrial output, retail sales, and consumer demand — typically support a country’s currency by attracting investment.
Labor market data
Employment reports help assess economic health and future consumption. Key indicators — including non-farm payrolls, unemployment, and wage growth — often trigger strong market reactions.
Trade and investment flows
Exporters earn foreign currency, which they often convert into domestic currency. Capital inflows from foreign investment also increase demand for the local currency.
Geopolitics
Wars, sanctions, elections, and political crises shift investor risk sentiment. During uncertainty, capital often flows toward perceived safe-haven currencies and assets.
