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

The Bank of Spain Resolution publishes the euro exchange rates for 28 January 2026, established by the ECB, which now take official effect pursuant to Article 36 of Law 46/1998. These rates supersede previous ones and must be used in financial transactions, contracts, and official communications. The change affects all sectors using the euro as a reference currency.

How it affects those involved

Traders, businesses, and individuals conducting international transactions must update their exchange rate calculations following the new publication.

The risk of discrepancies in pricing or payments increases if updates are not implemented promptly.
