How the Global Spot Currency Market Works

A spot foreign-exchange transaction is an agreement made today to exchange two currencies at an agreed rate for prompt delivery. Settlement commonly occurs two business days later, although the convention differs for some currency pairs and products.

Spot describes the settlement convention, not necessarily an exchange of physical notes. Banks and companies usually settle by moving balances through payment and correspondent-banking systems. A cash-counter rate is a retail price for banknotes and may differ from the wholesale spot market.

Foreign exchange is mainly an over-the-counter market. Banks, dealers and customers trade directly or through electronic platforms rather than on one central exchange with a single official price.

The Bank for International Settlements measured average global OTC foreign-exchange turnover of about US$9.6 trillion per day in April 2025. Spot accounted for 31% of that activity. The size of the market does not mean every currency pair or local market has equal liquidity.

A dealer normally quotes a bid, the price at which it buys the base currency, and an offer, the price at which it sells. The difference is the spread. Highly traded pairs often have narrower wholesale spreads than currencies traded less frequently.

The displayed mid-market or reference rate is not automatically available to a customer. The final retail rate can reflect the provider's margin, transaction size, payment method, operating costs, liquidity and risk, plus a separate fee.

Orders to buy and sell respond to trade, investment, remittances, interest-rate expectations, inflation, policy decisions, risk sentiment and political news. The rate can move because expectations change even before an economic event occurs.

In a market-based system, different banks can quote different rates at the same time. A central-bank reference or indicative rate can be a benchmark, but it should not be confused with a guaranteed transaction price.

A spot transaction settles promptly. A forward transaction fixes today the rate for an exchange on a later agreed date. Forward points reflect interest-rate differences and market conditions; they are not simply a prediction of where the future spot rate will be.
