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

The Bank of Spain Resolution publishes the official euro exchange rates for 27 January 2026, as established by the European Central Bank. These rates are official and must be used by companies, individuals, and public administrations in financial operations. The change directly affects the calculation of amounts in foreign currencies, particularly regarding exports, imports, and international transactions.

In 3 key points

  1. Official euro exchange rates are updated monthly in accordance with the ECB (art. 36 Ley 46/1998)
  2. 1 euro = 1.1929 US dollars (official rate for 27/01/2026) (cambio 1 euro = 1,1929 dólares USA)
  3. Rates are considered official from the date of their publication (art. 36 Ley 46/1998)

How it affects those involved

Businesses and individuals conducting transactions in foreign currencies must update their conversion calculations based on the new official rates. Public administrations managing international contracts or foreign currency payments must adjust their records. Financial advisors and export managers should communicate the new rates to their clients to prevent calculation errors. The risk of discrepancies in prices or costs may increase if updates are not implemented promptly.
