Benchmark indices Sensex and Nifty ended lower on Tuesday (August 11, 2026) as a sharp rally in crude oil prices due to geopolitical uncertainties dented investors' sentiment.

The 30-share BSE Sensex dropped 388.19 points, or 0.49%, to settle at 78,154.25. During the day, it tanked 494.18 points, or 0.62%, to 78,048.26.

The 50-share NSE Nifty declined 112.10 points, or 0.46%, to end at 24,471.70.

From the Sensex pack, UltraTech Cement, Axis Bank, InterGlobe Aviation, Bharti Airtel, Bajaj Finance and Power Grid were among the major laggards.

Eternal, Infosys, Titan, HCL Tech, and Tata Consultancy Services were the gainers.

Brent crude, the global oil benchmark, jumped 2.18 per cent to $89.63 per barrel.

"Indian equity benchmarks ended lower on Tuesday, with both Sensex and Nifty declining around 0.5 per cent and the Nifty 50 slipping below the 24,500-mark, as a rebound in crude oil prices and volatility associated with the weekly F&O expiry weighed on investor sentiment," Hariselvan Radhakrishnan, founder & CEO of HST Wealth, a research analyst firm, said.

The dominant headwind for the session remained the renewed surge in global oil prices, he added.

"Markets traded under pressure on Tuesday, extending their cautious tone amid renewed geopolitical concerns and rising crude oil prices. Investor sentiment remained subdued amid a renewed rise in crude oil prices, with Brent crude moving towards the USD 90 per barrel mark as hopes of an early US-Iran agreement faded," Ajit Mishra - SVP, research, Religare Broking Ltd, said.
