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 5 May 2026, established by the ECB, which now have official effect (Art. 36 of Law 46/1998). This change affects all parties using official exchange rates for financial transactions, trade, or accounting. Rates must be updated in internal records and currency conversion operations to avoid errors or penalties due to deviation.

In 2 key points

  1. The official exchange rates for 5 May 2026 serve as the official reference for financial transactions (art. 36 Ley 46/1998)
  2. 24 euro exchange rates against foreign currencies are established, including dollars, yen, pounds, etc. (texto fuente)

How it affects those involved

Business owners and individuals conducting international transactions must update their exchange rates to prevent errors in invoicing, payments, or profit calculations. Public administrations and financial institutions using official rates must adjust their internal systems. Financial advisors must inform clients about the new rates and ensure they are used in conversion operations. The risk of deviation in commercial transactions increases if updates are not made in a timely manner.
