Market dynamics are shifting as we enter the March 2026 series, with the National Stock Exchange (NSE) implementing a stringent 15% additional exposure margin on 18 specific stocks within the Futures and Options (F&O) segment. This regulatory move targets securities where the top 10 clients collectively hold more than 20% of the Market Wide Position Limit (MWPL). By increasing capital requirements for these concentrated positions, the exchange aims to curb excessive leverage and safeguard against systemic shocks in volatile equity derivatives. The list of affected securities includes high-profile names such as Vodafone Idea, SAIL, DLF, Bandhan Bank, and RBL Bank. Traders in these scrips will face the higher of either this new 15% exposure margin or existing surveillance margins, determined by three months of rolling data. In contrast to the tightening in equities, the NSE and MCX have moved to provide relief in the commodities space. Effective February 19, 2026, additional margins on gold and silver futures have been withdrawn. Gold futures saw the removal of a 3% additional margin, while silver futures benefited from a 7% reduction. This easing follows a period of extreme price swings where silver hit a peak of 3,50,000 per kg earlier in the month before retracing. As of February 20, 2026, the equity benchmarks are navigating a cautious environment. The Nifty 50 is holding steady near the 25,470 level, while the BSE Sensex remains positioned around 82,500. Market sentiment is currently balanced between strong domestic corporate earnings and rising geopolitical tensions in West Asia. These global uncertainties have pushed Brent crude prices toward the 72 dollar mark, adding a layer of risk for oil-importing economies. Precious metals are showing signs of a tentative recovery. Gold is trading near 1,56,640 per 10 grams, rebounding from recent lows. Silver has also regained ground, currently hovering around 2,70,100 per kg, as investors engage in bargain hunting following the significant margin relief. Institutional activity shows a trend of caution. Recent data indicates that Foreign Institutional Investors (FPIs) were net sellers to the tune of 880 crore, while Domestic Institutional Investors (DIIs) also recorded net sales of approximately 596 crore in the latest sessions. The combination of higher margins for concentrated stock positions and relaxed requirements for bullion indicates a strategic pivot by regulators to stabilize the broader financial ecosystem as the new month approaches.
