Market Impact: High — traders with existing positions in these 15 securities must provide additional margin by April 17, 2026 or face forced liquidation. The enhanced margin requirement (minimum 50%, maximum 100%) significantly increases the cost of holding these positions, likely causing reduced liquidity and selling pressure. Notably, NIACL (The New India Assurance Company Limited) is a large-cap PSU insurer, making its inclusion particularly significant. The nil addition to Stage II indicates no securities face the more stringent 100% mandatory margin at this time.

Impact Justification

Directly affects trading conditions for 15 securities by imposing enhanced margin requirements of up to 100%, significantly impacting traders holding or planning positions in these stocks from April 17, 2026.
