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

The Bank of Spain's resolution publishes the new euro exchange rates effective 8 January 2026, which are officially recognised under Article 36 of Law 46/1998. These rates replace previous ones and must be used in financial transactions, contracts, and official communications. The update is published in the BOE without requiring further action from users.

In 2 key points

  1. 1 euro = 1.1675 US dollars (official rate from 8/1/2026) (CAMBIOS)
  2. The changes are officially recognised pursuant to Article 36 of Law 46/1998 (art. 36 Ley 46/1998)

How it affects those involved

Traders, businesses and individuals carrying out international operations must update their foreign exchange calculations from 8 January 2026. Public authorities and financial services must use these rates in official operations. Advisors must inform their clients of the new exchange rates to prevent conversion errors. The risk of pricing or payment discrepancies increases if updates are not made in time.
