Impact Assessment

Operational Impact: Medium - The BSE StAR MF platform will have limited availability during specific time windows on a Saturday, which typically sees lower trading volumes. The two one-hour switching windows (8:30-9:30 AM and 11:30 AM-12:30 PM) will result in complete platform unavailability.

Market Impact: Low to Medium - Since the activity is scheduled for a Saturday and affects only the mutual fund platform, the overall market impact is limited. However, members conducting mutual fund transactions during these hours will need to plan accordingly.

Member Impact: Members actively using the BSE StAR MF platform on Saturday morning will need to adjust their operational schedules to accommodate the downtime windows. The advance notice allows for adequate planning.

Impact Justification

Scheduled maintenance with limited disruption to mutual fund trading platform operations during weekend hours
