Businesses and individuals: one month to update official euro exchange rates

The Bank of Spain publishes the official euro exchange rates for 25 February 2026, approved by the ECB, now deemed official under Article 36 of Law 46/1998. These rates replace previous ones and must be used in official financial operations such as payments, interest rates or international conversions. The change applies to all euro users in Spain, including businesses, individuals and public administrations.

In 2 key points

  1. 1 euro = 1.1784 US dollars (Art. 36 Law 46/1998) (art. 36 Ley 46/1998)
  2. Official rates published by the ECB and recognised as valid from 25 February 2026 (Resolución de 25 de febrero de 2026)

How it affects those involved

Businesses and individuals carrying out international transactions must update their currency conversion calculations using the new official rates. Financial institutions must adjust their internal systems to reflect the updated rates. Finance advisors and investment managers must inform their clients of the change. There is no direct risk of fines, but errors in conversion could affect costs or profits.
