This course covers Margin Maintenance Requirement, which involves defining and enforcing minimum margin levels within Loan Against Shares (LAS) Credit workflows to maintain adequate collateral coverage against market-linked exposures. It focuses on establishing structured controls that monitor borrower margin positions, manage Loan-to-Value (LTV) movements, and ensure timely corrective actions when collateral values decline or concentration risks increase in volatile securities-backed lending environments. The course evaluates key dimensions such as LTV monitoring, margin control, exposure management, and concentration limit oversight, with each requiring independent validation and documented rationale before any credit action is finalized. It is distinct from broader portfolio diversification strategies, as it focuses on exposure-level margin governance, collateral sufficiency management, and LAS-specific market risk control frameworks, rather than enterprise-wide diversification or strategic portfolio allocation approaches. Within LTV, Margin & Exposure Control, the credit manager validates team-level analysis, approves case recommendations, and manages segment-level exposure within Loan Against Shares (LAS) Credit, shaping escalation scope and credit committee priorities.
