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

The Bank of Spain Resolution publishes the official euro exchange rates for 16 January 2026, in accordance with the ECB, and establishes that these rates shall have official effect pursuant to Law 46/1998 (Art. 36). This change affects all parties conducting foreign currency transactions, as these rates become the official reference for calculating amounts in euros and other currencies.

In 2 key points

  1. Official exchange rates are updated daily according to the ECB (art. 36 Ley 46/1998)
  2. 1 euro = 1.1617 US dollars (and other currencies) (cambios del euro del 16 de enero de 2026)

How it affects those involved

Traders, businesses, and individuals conducting international transactions must update their price and cost calculations in foreign currencies based on the new official rates. Public administrations and financial services using these rates in their operations must also adjust their records. Financial advisors should inform their clients of the change to prevent errors in invoicing or payments.
