Businesses and individuals: 3 months to update official exchange rates or deviation risks

The Bank of Spain's resolution publishes the euro exchange rates from 5 June 2026 set by the ECB, which now take official effect under Article 36 of Law 46/1998. These rates replace previous ones and must be used in financial operations, contracts, and official communications. The change affects all users of exchange rates in Spain, particularly sectors dependent on international operations.

In 2 key points

  1. 1 euro = 1.1640 US dollars (official rate from 6/5/2026) (CAMBIOS)
  2. Official rates published by the ECB, considered valid under Article 36 of Law 46/1998 (art. 36 Ley 46/1998)

How it affects those involved

Business operators and individuals engaging in international transactions must update their foreign exchange calculations to avoid financial errors. Financial institutions should incorporate the new exchange rates into their calculation systems. Investment advisors and fund managers must review their products and contracts to ensure accuracy in values. Errors in application could lead to losses or discrepancies in payments and receipts.
