Impact Assessment

This mock session affects all ICCL clearing members who must temporarily redirect their system access to the SaaS-based ICCL@NCL instance during the drill window. There is no market-wide trading impact beyond the scheduled mock period. Members unprepared for the switchover may face temporary operational disruption during the test. The exercise is part of ongoing business continuity preparedness and does not affect listed securities or trading rules.

Impact Justification

Operational mock session affecting ICCL clearing members' system access; requires action from members but is a scheduled test with no permanent regulatory change.
