This weekend marks a major milestone in payments: the coexistence period between MT and ISO 20022 message standards ends. From 22 November 2025, all FI-to-FI payment instruction messages will be delivered only in ISO 20022 format.

ISO 20022 brings richer data, better compliance, and improved automation - but preparation is key to avoid NAK’ed messages and operational delays.

Be prepared for the weekend.

All FIN and FINplus Users are strongly advised not to send any message from Saturday 15:00 GMT till Sunday 05:00 GMT and to check Swift Knowledge Base for full details, troubleshooting guides, and contingency processing information.
