Impact Assessment

Market Impact: High - The additional exposure margin requirements on 18 securities will increase the cost of trading and reduce available leverage for market participants. This may lead to reduced liquidity and trading volumes in these stocks as traders face higher capital requirements.

Affected Sectors: Banking (RBL Bank, Bandhan Bank, LIC Housing Finance, PNB Housing Finance), Energy (JSW Energy, Petronet LNG), Metals (SAIL, NMDC), Pharmaceuticals (Aurobindo Pharma, Glenmark), Telecom (Vodafone Idea, Indus Towers), and FMCG (Patanjali Foods, Crompton Greaves).

Trading Strategy Impact: Traders and investors holding positions in these securities will need to allocate more capital for margin requirements, potentially forcing position reductions or portfolio rebalancing. Intraday traders may find these stocks less attractive due to higher margin costs.

Risk Management: The measure enhances market stability by preventing excessive concentration in these securities and reducing systemic risk from large position buildups.
