Know the difference

Reference exchange rate vs bank or payment-provider rate

Why a public reference rate may differ from the rate shown by a bank, card network, payment provider, broker, or exchange.

Short answer

A reference rate is a reproducible information point. A bank or payment-provider rate may include timing differences, spread, fees, liquidity, card-network rules, and customer-specific pricing. Use FXpeek for reference and evidence, and use the provider statement for the executed amount.

Common use cases

FAQ

Why is my bank rate different?

Banks and payment providers can apply their own timing, spread, fees, and pricing rules.

Is FXpeek a settlement quote?

No. FXpeek does not execute or guarantee a transaction.

Which number belongs in a reconciliation?

Keep both the executed provider amount and the separate reference-rate evidence when the workflow needs a variance explanation.

Reference note

Reference data explains and benchmarks a conversion; the provider record proves what was actually executed.
