Stock Indices Dip 2% as Iran-U.S. Tensions Escalate

Indian stock indices fell sharply on Wednesday, with the BSE Sensex and NSE Nifty both dipping 2% as renewed military clashes between Iran and the United States rattled global markets. The benchmark indices opened lower and stayed in the red through the session, dragged down by heavy selling in defence, energy, and banking stocks.

Markets in the red

The Sensex closed at 78,450, down 1,600 points from the previous close. The Nifty settled at 23,720, losing 480 points. The selloff was broad-based, but the worst hit were stocks with direct exposure to geopolitical risk.

Trading volumes were higher than average, with many investors cutting positions in mid-cap and small-cap names. Foreign portfolio investors were net sellers, pulling out an estimated ₹3,200 crore from equities on Wednesday alone.

Defence and oil stocks react

Shares of defence companies surged as the market priced in higher government spending on security. Hindustan Aeronautics and Bharat Electronics both rose over 4%. However, the broader market sentiment remained negative.

Oil marketing companies took a beating. BPCL, HPCL, and IOCL fell between 3% and 5% as crude oil prices spiked. Brent crude climbed past $92 a barrel, stoking fears of higher import costs and inflation for India, which imports over 85% of its oil needs.

Banking and auto stocks under pressure

Banking stocks were among the top losers. HDFC Bank, ICICI Bank, and SBI each fell over 2%. The Nifty Bank index dropped 2.3%, reflecting concerns that rising oil prices could hurt corporate margins and loan growth.

Auto stocks also slid, as investors worried about input cost pressures. Maruti Suzuki, Tata Motors, and Mahindra & Mahindra lost between 1.5% and 3%. Analysts said the sector is particularly vulnerable to any sustained rise in commodity prices.

Global cues and what comes next

The fall in Indian equities mirrored a global risk-off move. Asian markets closed lower, with Japan's Nikkei down 1.8% and Hong Kong's Hang Seng losing 1.5%. US futures were also pointing to a weak open.

Market participants are now watching for any diplomatic moves between Tehran and Washington. A quick de-escalation could bring relief, but any further military action may deepen the selloff. The coming sessions will likely see heightened volatility, with investors tracking crude oil prices and the rupee's movement against the dollar.
