ISO 20022 rollout for General Meetings – New implementation timeline


Following Announcement L22002, Clearstream Banking1 informs clients that the implementation of ISO 20022 for General Meeting (GM) messages is postponed from November 2023 and is currently planned on

8 April 2024

for simultaneous go-live with ECMS and SCoRE.

Impact on clients     

All clients will have to be ready to receive GM messages and instruct in ISO 20022 as of April 2024. The existing ISO 15022 messages for GMs will be decommissioned.

ISO 20022 messages will be exchanged via SwiftNet FINplus.

For clients using the Xact Web Portal, Clearstream Banking will implement a meeting event subdomain allowing to receive meeting notifications and send instructions accordingly.

Further information

Detailed implementation information including client testing and migration approach will be provided in due course.

For further information, please contact Clearstream Banking Client Services or your Relationship Manager.
