Reference exchange rate
A daily benchmark rate published by a central bank for information, accounting and statistics.
Updated 2026-07-26
A reference rate is fixed once per publication day from a defined procedure and published as a single number per currency. Its purpose is to give everyone a common figure for accounting, contracts, statistics and reporting.
It is not a price at which anyone will trade with you. It carries no bid and no ask, includes no spread and no fees, and no bank is obliged to deal at it. Actual conversion costs differ, sometimes by a lot for small amounts and thin currencies.
Reference rates are published only on business days of the publishing institution. There is no rate for a weekend or a holiday, and the honest response to a request for one is that it does not exist — not the previous day's number quietly reused.
