Margin trading regulation: revised eligibility, margin methodology and disclosure rules tighten broker prudential and reporting obligations. SEBI's revised framework permits Margin Trading Facility only in Group I equities, prescribes initial margins as VaR plus specified multiples of applicable ELM with permitted forms of margin and haircuts, and requires separate identification and daily mark-to-market of collateral and funded stocks; brokers must maintain continuous margins, make margin calls, and may liquidate only under conditions set out in a mandatory Rights and Obligations document. Brokers offering the facility must meet a minimum net worth, may borrow only from scheduled commercial banks or regulated NBFCs, observe leverage and per-client exposure caps, maintain detailed records and auditor certifications, and comply with daily disclosure requirements to exchanges which will publish scrip-wise gross outstanding exposures.
