Indian equity benchmarks, the 30-share BSE Sensex and the NSE Nifty50 index, experienced a significant downturn for the fourth consecutive trading session on Thursday, October 1, 2026. The Sensex plummeted 852.63 points (1.18%) to close at 71,627.66, while the Nifty50 dropped 262.15 points (1.16%) to 22,358.30.
The broader market also faced considerable pressure, with the Nifty Midcap 100 index falling 1.21% and the Nifty Smallcap 100 index declining 1.44%. India VIX, a key gauge of market volatility, surged by 10.21% to 14.87, indicating heightened investor anxiety.
Key Factors Driving the Market Downturn
Several critical factors contributed to the sharp sell-off in the Indian markets, creating a challenging environment for investors.
Persistent Foreign Institutional Investor (FII) Outflows
Foreign institutional investors continued their selling spree for the fifth consecutive session, offloading equities worth over Rs 10,148 crore on September 30 alone. In the final two sessions of September, FIIs sold more than Rs 20,000 crore worth of equities. In contrast, domestic institutional investors (DIIs) provided some support, purchasing equities worth Rs 11,271 crore on Wednesday.
VK Vijayakumar, Chief Investment Strategist at Geojit Investments, noted the sustained FII selling. "With the US 10-year bond yield rising further to 5.3 per cent, FIIs may continue to sell," Vijayakumar stated. He highlighted an apparent contradiction, explaining that while FIIs sold Rs 45,536 crore through exchanges in September, they invested Rs 9,676 crore through the primary market. This inconsistent activity, he suggested, could be due to the strength in US bond yields and expectations of further weakness in Indian large-caps.
Rising Crude Oil Prices
Elevated crude oil prices added significant pressure to market sentiment. Brent crude futures for December delivery climbed from $96.55 a barrel to reach a high of $100.20 a barrel during Thursday's trading. The surge past the $100 mark is a critical concern for India, as higher oil prices directly impact the country's import bill and can fuel domestic inflation.
Hariselvan Radhakrishnan, Founder & CEO of HST Wealth, cautioned that "unless yields cool alongside crude, India's recovery may remain concentrated rather than broad-based," underscoring the interconnectedness of these global factors.
Weakening Rupee
The Indian rupee also depreciated significantly, slipping past the crucial 96-per-dollar mark. The currency touched a low of 96.19 against the US dollar. This decline was largely attributed to the continued foreign fund outflows and the persistently high crude oil prices, further exacerbating the market's sell-off.
