Businesses and individuals: 30 days to update official euro exchange rates

The Bank of Spain's resolution publishes the official euro exchange rates for 28 May 2026 as set by the ECB, effective under Law 46/1998 (art. 36). These rates replace all previous ones up to publication date, affecting all sectors using official rates for monetary conversions, such as trade, services, and current accounts.

In 2 key points

  1. Official exchange rates are updated daily by the ECB (art. 36 Ley 46/1998)
  2. The rates published on 28 May 2026 are official from that date (Resolución de 28 de mayo de 2026)

How it affects those involved

Businesses, companies and individuals carrying out international transactions must update their foreign exchange calculations using the new official rates. Authorities and financial institutions managing currency conversions must apply these rates in their operations. Finance advisors should review their calculations and communicate the updates to their clients to avoid errors in invoicing or payments.
