Bears Maul Dalal Street: Sensex Plunges 1,236 Points Amid US-Iran Tensions and Institutional Sell-off

Market Snapshot

The Indian equity markets faced a wave of aggressive selling on Thursday, with the BSE Sensex crashing 1,236.11 points, or 1.48%, to settle at 82,498.14. Similarly, the NSE Nifty 50 dropped 365 points, or 1.41%, to end the session at 25,454.35. The volatility index, India VIX, surged by over 10% to 13.46, reflecting heightened investor anxiety. Market breadth was significantly weak, with nearly 3,000 stocks declining on the BSE compared to around 1,200 advances.

Institutional Flows: Cash Market

On February 19, 2026, both Foreign Institutional Investors (FIIs) and Domestic Institutional Investors (DIIs) were net sellers in the cash market, a rare alignment that intensified the downward pressure on indices.

• Foreign Institutional Investors (FIIs): Net sold equities worth ₹880.50 crore. (Gross Purchases: ₹8,614.90 crore; Gross Sales: ₹9,495.40 crore).
• Domestic Institutional Investors (DIIs): Net sold equities worth ₹596.20 crore. (Gross Purchases: ₹11,483.90 crore; Gross Sales: ₹12,080.10 crore).

Derivatives Market Activity

FII activity in the derivatives segment showed a clear "risk-off" sentiment, with significant selling in futures, though there was a massive spike in index options buying, likely for hedging purposes.

• Index Futures: Net Sell of ₹1,056.40 crore.
• Index Options: Net Buy of ₹10,642.60 crore.
• Stock Futures: Net Sell of ₹1,831.20 crore.
• Stock Options: Net Sell of ₹120.20 crore.

Key Drivers and Outlook

The primary catalyst for the crash was the credible threat of a U.S. military campaign against Iran, which sent global crude oil prices higher, with Brent crude crossing the $71 per barrel mark. This geopolitical instability, combined with hawkish minutes from the latest FOMC meeting suggesting a "higher for longer" interest rate regime in the U.S., prompted institutional players to lock in profits.

Technically, the Nifty 50 has slipped below its crucial 20-day Exponential Moving Average (EMA) of 25,650. Analysts suggest that if the index fails to reclaim the 25,500 level, it could test the next major support zone at 25,200–25,000. For the Sensex, the 82,000 mark remains a critical psychological floor in the near term.
