Businesses and individuals: 1 month to update official exchange rates in euros

The Bank of Spain publishes official exchange rates for the euro as of June 17, 2026, based on the European Central Bank, effective under Article 36 of Law 46/1998. These rates are now official for financial, international trade, and tax purposes, affecting all users requiring official conversion rates.

In 2 key points

  1. Official exchange rates are updated monthly by the ECB (Article 36 of Law 46/1998) (art. 36 Ley 46/1998)
  2. 1 euro = 1.1591 US dollars (official rate from 17/06/2026) (CAMBIOS)

How it affects those involved

Businesses and individuals carrying out international transactions must update their currency conversion calculations using the new official exchange rates. Public administrations and financial institutions that use the euro as a reference unit must adjust their internal systems. Financial advisers and accountants should review their calculations to avoid errors in declarations and payments. The change does not introduce new obligations, but rather requires a mandatory update of reference data.
