FX Spot Transaction

An FX spot transaction is an agreement to exchange one currency for another at the current market rate for settlement on the spot date, which is the standard short settlement period in the foreign exchange market. For most currency pairs the spot date is two business days after the trade (T+2), while for some pairs, such as US dollar against Canadian dollar, it is one business day (T+1). The rate used is the spot rate. Spot trades are the simplest and one of the largest segments of the foreign exchange market.

The spot market is used by companies paying for imports, investors buying foreign assets, payment providers funding payouts and traders speculating on short-term moves. It is distinguished from forward transactions, which settle on a later date at a rate set today, and from FX swaps, which combine two exchanges in opposite directions. When customers convert money through their bank or a payment provider, the underlying conversion is usually a spot transaction, even if the customer sees it as instant.

1. The buyer and seller agree the currency pair, amount, rate and value date, often through an electronic platform, a bank's dealing desk or a broker.
2. Both sides confirm the trade, typically through electronic confirmation and matching systems.
3. On the value date, each party pays the currency it sold, usually through correspondent accounts, and receives the currency it bought.

For example, a UK company buys 100,000 US dollars from its bank at a spot rate of 1.2700 dollars per pound. It pays $100{,}000 \div 1.2700 \approx 78{,}740$ pounds and receives 100,000 dollars two business days later, which it can use to pay a supplier.

The two-day convention dates back to the time when confirming trades and arranging payments across time zones took longer. It allows both parties to check the details, make payment instructions and move funds through correspondent banks and settlement systems in two different countries. Although modern technology could settle faster, the convention remains the market standard. Many retail and corporate payment providers settle customer conversions faster than the spot date by using their own liquidity, effectively bearing the timing gap.

Spot prices are quoted as a bid, at which a dealer will buy the base currency, and an offer, at which it will sell. The difference is the bid-ask spread. For major currency pairs in the interbank market, spreads are very narrow. Customers usually trade at wider spreads, with the provider adding a margin, often called an FX markup, to the market rate. The mid-market rate, halfway between bid and offer, is commonly used as a benchmark to judge the cost of a spot conversion. Large trades may be priced differently from small ones, and illiquid currencies carry wider spreads.

The spot market is decentralised and trades around the clock on weekdays. Dealers include large global banks, regional banks and non-bank liquidity providers. Electronic platforms, both multi-dealer venues and banks' own single-dealer platforms, handle much of the volume, and algorithmic and high-frequency trading firms play a large role in providing liquidity. Benchmarks, such as the WM/Reuters closing rates, are calculated from spot trading and used to value portfolios. Conduct in the market is guided by the FX Global Code, a set of principles developed by central banks and market participants after misconduct scandals in the 2010s.

Spot trades carry settlement risk, because each party pays its currency in its own country's payment system, often in different time zones, and one may pay without receiving. This risk, known historically as Herstatt risk, is reduced for major currencies by CLS, which settles both legs simultaneously. Trades outside CLS rely on bilateral arrangements and credit limits. There is also replacement cost risk if a counterparty fails before settlement and the trade must be replaced at a worse rate.

Payment and remittance firms use spot transactions to convert customer funds and to pre-fund accounts in destination countries. Because their customers may expect immediate delivery, they manage timing differences by holding balances in key currencies, using liquidity providers that settle the same day and monitoring their currency exposure between receiving customer funds and completing the spot trade. Some firms batch customer conversions into larger spot trades to obtain better rates.
