To act in concert with the global standard of adopting ISO 20022 in SWIFT and Hong Kong RTGS for payment-related SWIFT messages, HKCC and SEOCH have planned to migrate money settlement from existing SWIFT MT messages to ISO 20022 XML-based message ("MX messages") on 22 April 2024* tentatively (“MX Migration”).
As the scope of this MX Migration concerns the adoption of ISO 20022 standard for money settlement, it will require Settlement Banks of the clearing houses to take action on corresponding changes. Clearing Participants are not required to involve in the MX Migration since there is no related impact being brought by the migration. This page aims to provide Settlement Banks with a summary of HKCC/ SEOCH’s implementation plan and requirements for a seamless rollout in April 2024. For further details of MX Migration, Settlement Banks should reach out to their usual business contact point in HKCC and SEOCH.

Subject to further assessment, HKCC and SEOCH can provide transition period from Apr until end of 2024 to banks that are not ready for MX in Apr 2024 yet. Before the end of transition period, banks are required to ensure full readiness of MX messages that exchange with HKCC and SEOCH. Please reach out to your usual contact point from HKCC and SEOCH if banks need to utilize the transition period.
*Note: In case HKICL activates fallback of RTGS to MT messages on 21 April 2024, all MX enhancements of HKCC and SEOCH in this ISO MX migration will not launch on 22 April 2024. Existing MT messages will be expected to remain in use between Settlement Banks and HKSCC/ SEOCH.
