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

The Bank of Spain publishes the euro exchange rates from 5 February 2026 set by the ECB, now official 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 5 February 2026 are official and must be used in financial operations (art. 36 Ley 46/1998)
  2. 1 euro = 1.1798 US dollars (official rate from 5 February 2026) (texto fuente)

How it affects those involved

Businesses, companies and individuals carrying out international transactions must update their foreign exchange calculations to avoid errors in pricing, costs or payments. Financial institutions should review their internal systems to ensure they reflect the new exchange rates. Finance advisors should inform their clients about the updates. There is no direct penalty, but mistakes could lead to economic losses.
