FX and interest rate data

FX and interest rate data includes currency exchange rates, benchmark and reference rates, central bank policy rates and yield curves. Treasury and finance teams use it for accounting and revaluation, trading desks for pricing and risk, payments and e-commerce firms for currency conversion, and economists for research.

Typical fields:

• Currency pair or rate identifier
• Bid, ask and mid rates, or a fixing value
• Timestamp and time zone, with fixing time where relevant
• Tenor for forwards, swaps and yield curve points
• Source or contributing venue
• Rate type: spot, forward, official fixing, benchmark

Sources and collection

Spot rates are aggregated from trading venues, banks and liquidity providers. Official fixings and reference rates are published by central banks and benchmark administrators. Yield curves are built from government bond prices and swap rates, usually with a fitting model. Each method gives slightly different numbers, so the right source depends on whether you need tradable prices, accounting rates or official references.

Delivery and pricing

Delivered by REST API, streaming feed or daily files. Free central bank rates cover many accounting needs. Commercial pricing is usually a monthly or annual subscription tiered by update frequency, number of currency pairs, API call volume and history depth. Some benchmark rates require a licence from the benchmark administrator for certain uses.

Before you buy

• Decide whether you need tradable quotes, mid rates or official fixings.
• Check coverage of exotic and restricted currencies.
• Confirm the cut-off time used for end-of-day rates.
• Ask how gaps on holidays and weekends are filled.
• Review terms if rates will be shown to customers or used in contracts.
