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

The Bank of Spain Resolution publishes the Euro exchange rates for 3 March 2026, established by the ECB, which now have official effect (Art. 36 Law 46/1998). These rates supersede previous ones and must be used in financial transactions, contracts, and official communications. The change affects all foreign currency users in Spain, particularly regarding payments, interest rates, and conversions.

In 2 key points

  1. The exchange rates for 3 March 2026 are official for all financial purposes (art. 36 Ley 46/1998)
  2. 1 euro = 1.1606 US dollars (official rate from 03/03/2026) (texto fuente)

How it affects those involved

Businesses, individuals, and public administrations must update their exchange rate calculation systems to avoid errors in international payments or contracts. Banks and investment managers must adjust their official quotations. Financial advisors must inform their clients about the new rates. Using outdated rates may lead to losses or claims due to contractual deviation.
