What Is a Spot Rate?
A spot rate is the price quoted for an asset that will be delivered and paid for right away, or within a short standard settlement window. The term is used most often in the foreign exchange market, where a currency's spot rate is the exchange rate for trades that settle within about two business days. It is contrasted with a forward rate, which is agreed today for a transaction that will settle on a later date.
Spot prices also apply to commodities such as metals and energy, where the spot price reflects what a buyer would pay now for immediate delivery. Because it reflects current supply and demand, a spot rate can change continuously during trading hours.
Spot Rates in Fixed Income
In bond markets, the term has a more specific meaning. A spot rate is the interest rate that applies to a single cash flow received at one point in the future. It is usually inferred from a zero-coupon bond of the same maturity, since that bond pays no periodic interest and its return comes entirely from the difference between its purchase price and its face value. The series of spot rates across different maturities is closely related to the yield curve.
Each spot rate can be used to discount a future payment to its present value:
Present value = Future cash flow / (1 + spot rate)^years
For example, a payment received in two years is worth less today than the same amount received now, and the two-year spot rate measures how much less. Analysts use this approach to price bonds with multiple payments, since each payment can be discounted at the rate that matches its timing.
Why It Matters to Investors
Spot rates show what a security or currency is worth now, and they serve as the reference point for comparing prices across different delivery dates. Forward prices are typically derived from spot rates and interest rate differences between currencies, so knowing the spot rate helps explain why forward quotes differ from current prices. For individual investors, the most common everyday exposure is through currency conversion, where the spot rate is the baseline before any bank or broker markup, fee, or spread is added to the final cost.
