Firms and individuals: 3 months to update official exchange rates or risk pricing deviations

The Bank of Spain's resolution publishes the euro exchange rates from 4 May 2026 set by the ECB, now officially effective under Article 36 of Law 46/1998. These rates replace previous ones and must be used in commercial, financial, and pricing operations. Firms and individuals failing to update their calculations may face cost or revenue deviations.

In 2 key points

  1. The exchange rates effective from 4 May 2026 are now official and must be used in commercial transactions (art. 36 Ley 46/1998)
  2. 1 euro = 1.1700 US dollars (official rate from 4 May 2026) (texto fuente)

How it affects those involved

Individuals carrying out international purchases or sales may notice changes in their payments. Public authorities and price regulators must incorporate the new exchange rates into their systems. Financial advisers should inform clients about the updates to prevent errors in planning.
