Progress on AMI-SeCo Single Collateral Management Rulebook for Europe and Eurosystem Collateral Management System – Update VI
Note: This announcement, originally published on 1 December 2023 and updated on 15 December 2023, 15 February 2024, 26 September 2024, 17 October 2024 and 25 October 2025, has been further updated to include information on the implementation of SCoRE CA Standard 4.
Further to Announcements L22033 and L23025, LuxCSD1 informs its clients on an update to the implementation of the AMI-SeCo Single Collateral Management Rulebook for Europe (SCoRE) Standards and Eurosystem Collateral Management System (ECMS).
The ECB’s Governing Council has decided to reschedule the launch of ECMS to 16 June 2025, following an assessment conducted by the ECB Market Infrastructure Board (MIB).
The MIB concluded that "additional time was required to achieve sufficient readiness for a smooth go-live, despite the good progress made in the testing phase over the summer. The rescheduling will support national central banks of the euro area and the counterparties that will be joining the ECMS by enabling them to achieve sufficient testing coverage in a stable environment to ensure their readiness by the revised go-live date”.
Clients can find further information on the ECB website.
