Cross-border migration

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.

Contingency processing

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.

What MyGreed teaches

Users should understand both the legacy MT terminology they will still hear and the modern ISO 20022 payment-message environment.

Source / standards noteSWIFT standards evolve through standards releases. This page teaches message purpose and common concepts; banks should use the current official message specification for live traffic.
Remember thisIn 2026, teach MT103 historically and operationally — but teach ISO 20022 as the current cross-border payments standard.
