Companies and individuals: 3 months to update official exchange rates or deviation risks

The Bank of Spain publishes the official exchange rates of the euro for 19 May 2026 under Article 36 of Law 46/1998. These rates, such as euro to dollar or yen, are considered official for administrative and commercial purposes and affect all sectors using official exchange rates in financial or commercial operations.

In 2 key points

  1. 1 euro = 1.1620 US dollars (art. 36 Law 46/1998) (1 euro = 1,1620 dólares USA)
  2. All officially published exchange rates have legal effect in commercial transactions (art. 36 Law 46/1998) (de acuerdo con lo dispuesto en el artículo 36 de la Ley 46/1998)

How it affects those involved

Traders, businesses and individuals carrying out international operations must update their pricing and cost calculations with the new official exchange rates. Public authorities and financial institutions must use these rates in their official records. Financial advisers must review their reports and forecasts to adjust them to the new rates. The risk of conversion errors may increase if updates are not made in a timely manner.
