The amendments redefine key terms such as collateral, capital market intermediaries (CMIs), eligible securities, loan-to-value (LTV), and margin. A new framework for loans against eligible securities prescribes LTV ceilings, valuation norms, prudential limits, and monitoring requirements. Certain loans are prohibited, including those against own securities, partly paid shares, and locked-in securities. The credit facilities to CMIs, permits specific financing activities while restricting lending for proprietary trading unless fully secured. All such exposures are to be treated as capital market exposure (CME).
