Description of enhancement of settlement efficiency

The implementation of Change Request T2S-0827-URD represents an enhancement to the existing partial settlement functionality within the TARGET2-Securities (T2S) platform.

With the implementation of T2S-0827-URD, T2S will immediately attempt settlement upon the partial release of an instruction. If settlement is feasible, meaning the necessary securities and cash are available, it will proceed without waiting for the next window. However, if settlement is not possible at that moment, T2S will defer the attempt until the next scheduled Partial Settlement Window.

This change does not introduce a new service but rather improves the responsiveness and efficiency of the existing partial settlement process. It ensures that settlement opportunities are not missed between windows, thereby optimising liquidity and operational throughput.
