Businesses and individuals: 3-month window to update official exchange rates or face deviation risks

The Bank of Spain Resolution publishes the Euro exchange rates for 7 April 2026, established by the ECB, which now have official effect (Art. 36 Law 46/1998). These rates supersede previous ones and must be used for financial transactions, contracts, and tax returns. This change affects all foreign currency users in Spain, particularly regarding international payments, interest rates, and currency conversions.

In 2 key points

  1. Official exchange rates will be updated on 7 April 2026 and must be used in financial transactions (art. 36 Ley 46/1998)
  2. The Bank of Spain publishes ECB rates as official for use in Spain (Resolución de 7 de abril de 2026)

How it affects those involved

Businesses and individuals making international payments or entering into foreign currency contracts must update their calculations using the new official rates from 7 April. Tax authorities and banks must apply these rates to declarations and transactions. Financial advisors should review their calculations and adjust reports to prevent errors in asset or debt valuation. The risk of discrepancy in previous operations may increase if updates are not completed on time.
