Impact Assessment

Operational Impact: High - This is a mandatory system migration affecting all clearing members, custodians, and Professional Clearing Members (PCM). Failure to complete role configuration before December 15, 2025 will result in loss of access to critical collateral management functions including collateral release, EMI operations, and reporting capabilities.

Affected Services:

  1. Collateral Release operations (requests, inquiries, file uploads/downloads)
  2. Early Margin Income (EMI) - cash and G-sec deposits
  3. Critical reports (quantity breach, direct pledge securities)

Business Continuity: Members have a 14-day window (December 01-15) to complete the transition. The tight timeline requires immediate action planning to prevent service disruptions in collateral operations which are essential for daily clearing activities.

Technical Requirements: Super admin users need to familiarize themselves with NMASS role management and the new interface using the provided user manual to ensure smooth transition.

Impact Justification

Critical system migration affecting all clearing members and custodians requiring mandatory action before December 15, 2025 to avoid operational disruptions in collateral management services.
