Businesses and individuals: 3 months to update official exchange rates or risk discrepancies

The Bank of Spain Resolution publishes the euro exchange rates for 9 April 2026, established by the ECB, which now have official effect (Art. 36 of Law 46/1998). These rates supersede previous ones and must be used in financial transactions, contracts, and official communications. This change affects all parties using the euro as a reference currency.

In 2 key points

  1. The exchange rates for 9 April 2026 are official and must be used in financial transactions (art. 36 de la Ley 46/1998)
  2. According to the resolution, the euro is converted at 1.1685 US dollars and 185.70 Japanese yen (cambios del euro del 9 de abril de 2026)

How it affects those involved

Businesses, individuals, and public administrations conducting international transactions must update their financial calculations with the new official rates. Financial advisors and asset managers should review reports and contracts to prevent conversion errors. Traders operating in foreign currencies risk discrepancies if they fail to update their records. While the Bank of Spain does not set compliance deadlines, the rates take effect immediately.
