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 17 April 2026 set by the ECB, now officially effective under Article 36 of Law 46/1998. These rates affect all parties conducting international transactions in foreign currencies, as they are used for financial calculations, contracts, or payments. The rates are published in the BOE and are valid from the date of publication.
