Businesses and individuals: 1 month to update official exchange rates in euros

The Bank of Spain publishes the euro exchange rates effective 23 February 2026, approved by the ECB, which are now official under Article 36 of Law 46/1998 (art. 36). These rates replace previous ones and must be used in financial operations, contracts, and official communications. The change affects all users of the euro in Spain, including businesses, individuals, and administrations.

In 2 key points

  1. Official exchange rates are updated every 24 hours according to the ECB (Art. 36) (art. 36)
  2. 1 euro = 1.1784 US dollars (updated as of 23/02/2026) (CAMBIOS)

How it affects those involved

Businesses and individuals must update their financial calculations and contracts with the new exchange rates to avoid errors in pricing, payments, or interest rates. Public administrations must adjust their official communications and monetary records. Financial advisors must inform their clients about the new rates and review their operations. The risk of discrepancies in payments or costs can be significant if updates are not made in a timely manner.
