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

The Bank of Spain publishes the euro exchange rates as of May 29, 2026, set by the ECB, which now have official status (Art. 36 of Law 46/1998). These rates must be incorporated into financial records of businesses and individuals dealing in foreign currencies. The change impacts all users of official exchange rates, especially in international transactions or account closures.
