Did SWIFT cross-border payment instruction coexistence between MT and ISO 20022 end in November 2025?
Learn why 2026 cross-border payment education cannot stop at MT103.
MT103 has long been used for single-customer credit transfer information and remains familiar market language.
For SWIFT cross-border payment instructions, the MT/ISO 20022 coexistence period ended on 22 November 2025. ISO 20022 is now the standard language for CBPR+ cross-border payments.
Some legacy MT payment instructions, including certain MT103 variants, may be subject to contingency conversion/processing rather than being the preferred native cross-border format.
Users should understand both the legacy MT terminology they will still hear and the modern ISO 20022 payment-message environment.
