Equity benchmark indices Sensex and Nifty tumbled more than 1 per cent on Tuesday, dragged down by heavy losses in IT stocks amid concerns over artificial intelligence-led disruption and renewed trade-related uncertainties.

Rising global crude prices amid escalating US-Iran tensions and sluggish global cues also hit investor sentiment, traders said.

The 30-share BSE Sensex plummeted 1,068.74 points, or 1.28 per cent, to settle at 82,225.92. During the day, the benchmark plunged 1,359.93 points, or 1.63 per cent, to hit an intraday low of 81,934.73.

The 50-share NSE Nifty fell 288.35 points, or 1.12 per cent, to close at 25,424.65. In the intraday session, it depreciated by 385.4 points, or 1.49 per cent, to hit a low of 25,327.60.

"Domestic markets registered a sharp decline, led by significant weakness in IT stocks amid renewed global concerns over AI-driven disruption and margin pressures for traditional service providers," Vinod Nair, Head of Research, Geojit Investments Ltd, said.

Global trade and tariff worries resurfaced as well, with additional pressure arising from Trump's warnings on trade deals and reports of possible national-security tariffs, he added.

Tech Mahindra emerged as the biggest laggard, declining by 6.6 per cent, followed by HCL Technologies, Eternal, Infosys, Tata Consultancy Services, Larsen & Toubro, Trent, Bharti Airtel, HDFC Bank, Bharat Electronics Ltd and ICICI Bank.

On the other hand, NTPC, Hindustan Unilever, Tata Steel, PowerGrid, Titan, Reliance Industries, Axis Bank, and Sun Pharmaceuticals were among the gainers.

Broader indices also ended in the negative territory, with the BSE Smallcap Select Index falling 0.68 per cent, while the Midcap Select Index slipped 0.54 per cent.

Nair further said that realty stocks also came under strain on expectations that prolonged stress in the IT sector could weigh on real estate demand and valuations.

In Asian markets, South Korea's Kospi, Shanghai's SSE Composite Index and Japan's Nikkei 225 benchmark ended higher, while Hong Kong's Hang Seng closed in red territory.

European stock markets were trading lower in mid-session deals, with Germany's DAX, London's FTSE 100 and Paris' CAC 40 trading down up to 0.27 per cent.

"Meanwhile, escalating US-Iran tensions, marked by embassy staff evacuations and Iran's warnings of wider regional escalation, intensified risk aversion. Overall, markets remain highly sensitive to geopolitical risks and sector-specific pressures, driving investors toward defensive, domestically focused segments," Nair said.

The US equity market ended nearly 2 per cent lower on Monday.

Brent Crude, the global oil benchmark, rose 0.22 per cent to USD 71.66 per barrel.
