Businesses and individuals: one month to update official euro exchange rates

The Bank of Spain Resolution publishes the official euro exchange rates for 13 January 2026, approved by the ECB, which now have legal effect (Art. 36 of Law 46/1998). These rates supersede previous ones and must be used in official financial transactions. This change affects all sectors performing currency conversions, particularly international trade, financial services, and foreign currency payments.

In 3 key points

  1. Official euro exchange rates are updated daily according to the ECB (Art. 36 Law 46/1998) (art. 36 Ley 46/1998)
  2. 1 euro = 1.1654 US dollars (official rate for 13/01/2026) (cambio 1 euro = 1,1654 dólares USA)
  3. Rates apply to official financial and commercial transactions (cambios del euro publicados por el BCE)

How it affects those involved

Traders and companies conducting international operations must update their exchange rate calculations to avoid errors in pricing, costs, or profits. Individuals making foreign currency payments or purchasing foreign products must also use the new rates. Financial institutions must adjust their internal systems and communicate the new rates to their clients. Financial advisors must update their references to provide accurate information.
