Spot Rate

The spot rate is the price at which one currency can be exchanged for another for settlement on the standard near-term value date, as opposed to a later date agreed in advance. Although "spot" suggests immediacy, the term is a market convention: in most currency pairs the spot value date is two business days after the trade date, written T+2.

The spot rate is the reference point for nearly every other price in foreign exchange. Forward rates, swap prices and the rates offered to retail customers by banks and money transfer operators are all built from it.

The two-day convention dates from an era when confirmations, funding instructions and payments between banks in different time zones took time to process. It has persisted because it gives both sides time to confirm the trade and move funds through their nostro accounts. There are exceptions. USD/CAD spot settles T+1, as do a few other pairs by convention, and value dates must skip holidays in both currencies' home markets and, for most pairs, US holidays as well because the dollar leg settles in New York.

Large interbank trades in major currencies are commonly settled through Continuous Linked Settlement (CLS), which applies payment versus payment so that neither side pays away its currency without receiving the other. This reduces the settlement risk associated with the two legs of a spot trade.

Spot is quoted as the amount of the quote currency per one unit of the base currency. A dealer shows two prices: the bid, at which it buys the base currency, and the offer, at which it sells. The midpoint is the mid-market rate, and the gap between bid and offer is the FX spread. Prices are usually given to four decimal places, with each 0.0001 called a pip; yen pairs are quoted to two.

There is no single official spot rate. Prices are formed continuously across electronic platforms and dealer banks in an over-the-counter market. Published benchmarks, such as the WM/Reuters 4 p.m. London fix or a central bank's daily reference rate, are snapshots used for valuation and contracts, not tradable prices.

Suppose EUR/USD is quoted 1.0848/1.0852. A US importer that must pay a supplier €500,000 buys euros at the offer of 1.0852 and owes $542,600 for value two business days later. A European exporter selling $1,000,000 into euros at the same moment would sell dollars at the bid and receive about €921,830. The mid-market rate is 1.0850, and the spread on each side is two pips. A retail customer would typically see a wider spread plus any FX markup added by the provider.

A forward contract fixes a rate today for settlement on a later date. The forward rate equals the spot rate adjusted by forward points, which reflect the interest-rate difference between the two currencies over the period (covered interest parity), plus any cross-currency basis. The forward rate is not a forecast of the future spot rate. An FX swap combines a spot transaction with an offsetting forward, and is the most heavily traded FX instrument by volume according to BIS surveys.

Spot rates under a floating exchange rate respond to interest-rate expectations, inflation, trade and capital flows, risk sentiment and central bank intervention. Under a peg or currency board, the authorities hold the spot rate within a band. Where capital controls are strict, an official spot rate may coexist with a parallel rate, and the onshore and offshore markets for the same currency can diverge, as seen in the CNY-CNH spread.

For payment firms, the spot rate is the cost base for customer conversions. A remittance company that quotes a customer a rate locks in a margin over the spot rate, then hedges or covers the position in the interbank market. Because spot settles T+2, while many customer payouts are expected within hours, operators must pre-fund destination accounts or manage the timing gap, a central issue in cross-border money transfer treasury.
