Nifty Today: Sensex and Nifty 50 Plunge as Oil Prices Surge and Geopolitical Tensions Rise

The Indian stock market witnessed a significant downturn on 28 September 2026, with the nifty today and the BSE Sensex recording sharp declines. The sell-off was triggered by a combination of surging crude oil prices, escalating geopolitical tensions between the US and Iran, and rising global bond yields, which collectively dampened investor sentiment across Dalal Street.

Market Performance: Nifty 50 and Sensex Crash

The 30-share BSE Sensex plunged 1,124.02 points, or 1.52%, to settle at 72,771.72, marking its lowest closing level since 30 March 2026 [1]. Simultaneously, the nifty 50 slid more than 360 points, ending the session below the 22,800 mark [2].

The impact on market valuation was severe. Reports indicate that the rout wiped out between Rs 6 lakh crore and Rs 8 lakh crore from the total market capitalisation of BSE-listed companies [1], [2].

Key Drivers Behind the Market Sell-Off

Several global and domestic factors converged to create a negative risk appetite among investors:

• Surging Crude Oil: Brent crude futures rose nearly 4% to reach approximately $108.2 per barrel [2]. This spike followed US President Donald Trump's rejection of an Iranian peace proposal to reopen the Strait of Hormuz [1].
• Rupee Pressure: The Indian rupee slipped to 95.9825 per dollar, its weakest level in over a week, as high energy prices and geopolitical uncertainty weighed on the currency [2].
• FII Outflows: Foreign institutional investors (FIIs) continued their selling streak, with provisional data showing they were net sellers of Indian shares worth Rs 36.94 billion (approximately $385 million) on the day [1].
• Bond Yields: Rising US and global bond yields added to the negative bias, pushing investors away from equities [2].

Sectoral Impact and Technical Outlook

The bse sensex and Nifty witnessed broad-based selling, with PSU banks and metal stocks emerging as the top drags [2]. Financials, realty, and energy-related segments also faced significant pressure, while the IT sector remained relatively resilient [1].

From a technical perspective, analysts suggest that the Nifty 50 faces strong resistance at the 23,000 level. Immediate support is seen between 22,650 and 22,700; a break below this range could lead to further short-term corrections [2].
