From Voda Idea, NBCC to RBL Bank: NSE to levy additional 15% margin on 18 stocks in March seriesUnder the new framework, an additional 15% margin will be levied in cases where the top 10 clients account for more than 20% of the market-wide position limits.By Sudarshan Kumar | Meghna Sen February 19, 2026, 1:57:53 PM IST (Updated)2 Min ReadThe National Stock Exchange (NSE) has announced an additional 15% margin requirement on select stocks with high market-wide position limits (MWPL).
Under the new framework, an additional 15% margin will be levied in cases where the top 10 clients account for more than 20% of MWPL in a stock. The exchange said the move is aimed at curbing concentration risk in derivatives positions.
For the March series, the NSE has released a list of 18 stocks that will attract the additional margin.
These include Aditya Birla Capital, Aurobindo Pharma, Bandhan Bank, Container Corporation of India, Crompton Greaves Consumer Electricals, Glenmark Pharmaceuticals, Vodafone Idea, JSW Energy, LIC Housing Finance, NBCC (India), NMDC, Patanjali Foods, RBL Bank, Steel Authority of India, Sammaan Capital, DLF, Manappuram Finance and Indus Towers.
The additional 15% margin will also apply to stocks that are already under the Additional Surveillance Measure (ASM) framework.
Stocks will be identified under this mechanism based on three-month rolling data, and the list will be reviewed on a monthly basis.
In the case of Aditya Birla Capital, the current exposure margin stands at ₹2.01 lakh.
With the additional 15% requirement, traders will need to bring in around ₹30,203 more, taking the total exposure margin to approximately ₹2.31 lakh from March.
