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 9 April 2026 set by the ECB, now officially effective 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 applies to all parties using the euro as a reference currency.

In 2 key points

  1. The exchange rates from 9 April 2026 are official and must be used in financial operations (art. 36 de la Ley 46/1998)
  2. The euro is equivalent to 1.1685 US dollars and 185.70 Japanese yen according to the resolution (cambios del euro del 9 de abril de 2026)

How it affects those involved

Business operators, individuals and public administrations carrying out international transactions must update their financial calculations with the new official exchange rates. Financial advisers and fund managers should review their reports and contracts to avoid errors in currency conversions. Traders operating in foreign currencies are at risk of discrepancies if they do not update their records. The Bank of Spain has not set any compliance deadlines, but the rates come into effect immediately.
