ISO 20022 rollout for General Meetings – New implementation timeline – Update II

26.01.2024

Note: This Announcement, originally published on 5 April 2023 and updated on 12 June 2023, has been further updated to include information on impacts and testing. Changes are highlighted.

Clearstream Banking1 reminds clients that the implementation of ISO 20022 messaging for general meetings (GMs) is planned for

18 November 2024

Impact on clients     

All clients using the Clearstream General Meeting Service will have to be ready to receive GM messages and instruct in ISO 20022 as of November 2024. The existing ISO 15022 messages for GMs will be decommissioned. With the exception of the notifications, for which a MT564 coexistence will continue to exist, the existing ISO 15022 messages for GMs will be decommissioned. Please note that for instructions, ISO 15022 messages will not be supported. All client instructions in ISO 15022 will be rejected (including MT599). Alternatively, instructions can be submitted via Xact Web Portal.

ISO 20022 messages will be exchanged via SwiftNet FINplus. Clients will need to ensure their connectivity, including new message subscriptions and, if necessary, a new RMA key exchange to allow transmission of messages via the SwiftNet FINplus network. 

For clients which do not support the ISO 20022 message format for meeting instructions, Clearstream Banking will provide a new General Meeting module within Xact Web Portal as an alternative. This will be available from 18 November 2024 and will offer multiple dedicated query options, standardised fields and ways to create or manage instructions manually. 

Clearstream Banking will publish a document detailing the changes for clients by the end of Q1 2024. Furthermore, the ISO 20022 messages for GMs used by Clearstream Banking will be documented on Swift MyStandards. Clients can refer to this site for an overview of the message structure, allowed fields or specific conditions. These specifications are planned to be published in Q1 2024.

Client testing

Client testing is planned for Q3 2024. Detailed information and the registration form will be provided in due course on the General Meeting Service web page.
