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

The Bank of Spain's resolution publishes the euro exchange rates from 3 February 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 financial operations, contracts, and official communications. The change affects all sectors using the euro as a reference currency.

In 2 key points

  1. The exchange rates effective from 3 February 2026 are official and must be used in financial operations (art. 36 de la Ley 46/1998)
  2. 1 euro = 1.1801 US dollars (official rate from 3 February 2026) (texto fuente)

How it affects those involved

Businesses, companies and individuals carrying out international operations must update their foreign exchange calculations to avoid errors in pricing, payments or contracts. Public authorities and financial institutions must incorporate the new exchange rates into their internal systems. Finance advisors must inform their clients about the new rates to ensure accurate calculations. The risk of deviation in operations may increase if updates are not made in a timely manner.
