These rates supersede previous ones and must be used in financial transactions, contracts, and official communications. This change affects all users of exchange rates in Spain, particularly in sectors reliant on international operations.

In 2 key points

  1. 1 euro = 1.1640 US dollars (official rate from 05/06/2026) (CAMBIOS)
  2. Official rates published by the ECB, deemed valid under Article 36 of Law 46/1998 (art. 36 Ley 46/1998)

Financial institutions must integrate the new rates into their calculation systems. Advisors and investment managers should review their products and contracts to ensure valuation accuracy.
