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

The Bank of Spain publishes official exchange rates for the euro as of April 21, 2026, which are now valid for all financial records (Art. 36 of Law 46/1998). These rates replace previous ones and must be applied in currency conversion operations, especially in current accounts, international payments, and balance sheets.

In 2 key points

  1. Official euro exchange rates are updated daily according to the ECB and are considered valid from the date of publication (21/04/2026) (art. 36 Ley 46/1998)
  2. The rates published in this resolution supersede previous ones for all financial purposes (art. 36 Ley 46/1998)

How it affects those involved

For companies and individuals conducting international transactions, it is mandatory to update financial records with the new exchange rates as of 21 April 2026. Public administrations and financial institutions must synchronise their calculation systems. Financial advisors and current account managers must review their calculations to prevent errors in payments or declarations. Conversion errors may lead to discrepancies in the calculation of taxes or profits.
