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.

For an Ethiopian bank customer, the practical comparison is the executable buying or selling rate, any fee, the permitted transaction type and the expected settlement. Ethiopian Forex compares published bank rates; confirm the final quote and eligibility directly with the bank before acting.

Compare quotes for the same currency pair, direction, amount and payment method, and check them at roughly the same time. A displayed reference rate may be a midpoint or an indicative figure. It is not necessarily the rate available for a cash exchange, card payment or bank transfer.

Ask how much the recipient will get after the provider's exchange rate and visible fee. For an international bank transfer, ask whether an intermediary or receiving bank may deduct a charge. In Ethiopia, the National Bank's indicative daily rate is a volume-weighted average based on banks' previous-business-day transactions; banks and authorized dealers set their own customer rates. A quote should be checked against the exact service you need. A banknote exchange, a transfer between accounts and an international remittance may use different rates, charges and settlement procedures even when the same currency pair appears on the screen. For a business, the dealing date and settlement date both matter. The spot rate is agreed when the trade is booked, but the currency may move through banking systems later under normal settlement conventions. If funds arrive late or account details are incomplete, the payment can be delayed even though the exchange rate was fixed.
