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.

In 2 key points

  1. Official exchange rates are updated each time the ECB publishes new rates (17/04/2026) (art. 36 Ley 46/1998)
  2. Rates published have official effect from the date of publication in the BOE (art. 36 Ley 46/1998)

How it affects those involved

Businesses and individuals carrying out international transactions must update their financial calculations with the new official exchange rates to avoid errors in payments, invoices or contracts. Financial institutions and fund managers must adjust their internal systems to reflect the updated rates. Advisors should inform their clients about the change and check whether there is an impact on costs or profits. The risk of rate deviation may increase if updates are not made in a timely manner.
