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

The Bank of Spain Resolution publishes the Euro exchange rates for 17 April 2026, established by the ECB, which now have official effect (Art. 36 of Law 46/1998). This change affects all parties conducting international foreign currency transactions, as these official rates are used for financial calculations, contracts, or payments. The rates are published in the BOE and are considered valid from the date of publication.

In 2 key points

  1. Official exchange rates are updated whenever the ECB publishes new rates (17/04/2026) (art. 36 Ley 46/1998)
  2. Published rates take official effect from their publication in the BOE (art. 36 Ley 46/1998)

How it affects those involved

Businesses and individuals conducting international transactions must update their financial calculations with the new official rates to avoid errors in payments, invoices, or contracts. Financial institutions and fund managers must adjust their internal systems to reflect the new rates. Advisors should inform their clients of the change and verify any impact on costs or profits. The risk of rate deviation may increase if updates are not performed in a timely manner.
