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.

In 2 key points

  1. Official exchange rates are updated to 1 euro = 1.1644 US dollars (Art. 36 Law 46/1998) (art. 36 Ley 46/1998)
  2. These rates must be incorporated into the financial records of companies and individuals (Art. 36 Law 46/1998) (art. 36 Ley 46/1998)

How it affects those involved

Companies conducting foreign exchange operations must update their financial records with the new exchange rates to comply with regulations. Individuals managing foreign currency accounts or making international payments should review their calculations. Financial advisers must ensure their clients use official exchange rates to avoid errors in declarations or payments. Public administrations are not directly affected, but may use these rates in their own calculations.
