Businesses and individuals: 3 months to update official exchange rates or risk discrepancies

The Bank of Spain Resolution publishes the euro exchange rates for 5 February 2026, established by the ECB, which are now official under Article 36 of Law 46/1998. These rates supersede previous ones and must be used in financial transactions, contracts, and official communications. This change affects all sectors using the euro as a reference currency.

In 2 key points

  1. The exchange rates for 5 February 2026 are official and must be used in financial transactions (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

Traders, businesses, and individuals conducting international transactions must update their exchange rate calculations to avoid errors in pricing, costs, or payments. Financial institutions must review their internal systems to reflect the new rates. Financial advisors should inform their clients of these updates. While there are no direct penalties, errors may lead to financial losses.
