Sensex crash 2026: 5 triggers behind IT-led selloff

What happened in the market session

Indian equities saw a sharp downdraft as the BSE Sensex and Nifty50 declined amid heavy selling in large, index-heavy names. The fall was linked to weak global cues and a renewed selloff in information technology stocks after a brief recovery a day earlier. Market sentiment was also pressured by investor uncertainty around US President Donald Trump’s tariff policies, along with broader risk-off positioning. The session remained volatile, with selling intensity picking up later in the day according to commentary that flagged a sharp move around 3:00 pm. Broader markets also slipped, with multiple sectoral indices ending in the red. Reports highlighted losses in major stocks including Reliance and Zomato alongside the sector-wide slide.

IT stocks led the decline

Information technology was described as the central story of the day, with fresh pressure returning after a temporary recovery on Monday following the previous week’s sharp decline. Shares of TCS, Infosys and Wipro fell more than 3% as concerns grew around AI-driven disruption and a slowdown in technology spending. Another market account described a deeper, stock-specific selloff where Infosys fell 7%, while TCS, HCL Tech and Tech Mahindra dropped 4% to 6%. The Nifty IT index was cited as the biggest laggard, ending the session more than 2% lower. Separately, the same day’s move was also described as a sharper drop of about 4.98% for Nifty IT in a session marked by profit booking and fresh selling.

Accenture forecast cut added to the pressure

The IT weakness was linked to global demand cues after Accenture lowered the upper end of its annual revenue growth forecast. That development revived concerns about subdued discretionary spending by global corporations, a key driver for Indian IT exporters. The market narrative also cited fears of AI-related disruption, which has intensified debates on how quickly traditional service lines can adapt. With IT being a major export-facing sector, shifts in global corporate technology budgets tend to transmit quickly into Indian equities. The renewed selling also came after a prior rally, with one reference noting that profit booking reversed an earlier June 2 surge of 4.26% in IT stocks.

Global risks: US-Iran tensions and crude oil spike

Geopolitical anxiety remained a key overhang, with uncertainty over US-Iran peace talks and an escalation of the US-Iran conflict said to be in focus on June 3, 2026. Reports also noted that talks between the US and Iran over Tehran’s nuclear programme ended without a deal on Thursday, raising fears of further escalation in the Middle East. A rise in crude oil prices compounded the risk-off tone, with a fresh spike in oil explicitly cited as a drag on benchmarks. Higher crude tends to raise India’s import bill and can add pressure on the rupee and inflation expectations, which markets usually price in quickly.

Weak global cues and tech-led pressure overseas

Asian markets were described as lower, with South Korea’s Kospi, Japan’s Nikkei 225 and Shanghai’s SSE Composite index quoting down. In the US, markets ended mostly lower on Thursday, while the S&P 500 and European equities finished in the red after Nvidia’s quarterly earnings. Despite better-than-expected results and revenue guidance of USD 78 billion for the first quarter, Nvidia shares fell 5.5%, weighing on semiconductor stocks and overall sentiment. Tech-heavy Asian indices tracked losses in the Nasdaq, feeding into caution around export-linked Indian sectors such as IT.

Foreign selling, volatility rise and a weaker rupee

Foreign fund outflows were repeatedly flagged as a key pressure point. One data point said FIIs offloaded equities worth Rs 3,465.99 crore on Thursday, while another reference described heavy FII selling of more than Rs 7,500 crore. Volatility also rose, with India VIX up nearly 3% to 13.44, indicating higher uncertainty and a more cautious trading environment. The rupee was reported to have declined 4 paise to 90.95 against the US dollar on Friday, weighed down by FII outflows and weakness in domestic equities. Separately, rupee weakness was also linked to the US proposing new tariffs on imports from India.

Sectoral damage beyond IT

While IT led the decline, the selloff broadened across the market. Metals and PSU banks were cited as showing sharp weakness after IT. Another market note pointed to Nifty real estate as one of the top sectoral losers, with Nifty Auto, Nifty FMCG and Nifty Metal also under pressure. This breadth mattered because it suggested the fall was not confined to one pocket of the market, even if IT was the primary drag. In such sessions, index moves can accelerate as multiple sectors contribute simultaneously.

Late-session drop, algo chatter and MSCI rebalancing talk

A separate transcript-style market commentary highlighted a sharp fall around 3:00 pm, attributing it to possible algo-driven trades. It also mentioned MSCI rebalancing as a potential contributor, while noting that MSCI-linked activity typically occurs in the last 15 to 30 minutes of trade. The same commentary observed that the market was trading below key daily moving averages, including the 50, 100 and 200 DMA, a technical setup that can amplify downside moves when selling intensifies. The late fall was described as about 150 points in that segment of the move.

What market participants said

Hariprasad K, Research Analyst and Founder at Livelong Wealth, described the day as highly volatile, citing geopolitical concerns, elevated crude prices and a sharp IT sell-off as key drags. He added that the sharp correction in IT was the key story of the day. The combination of global and domestic triggers kept investors cautious, with several reports highlighting risk-off behaviour and persistent overseas selling.

Key facts at a glance

Why this selloff mattered

The session underscored how quickly export-facing sectors like IT can drive headline indices when global demand signals deteriorate. Accenture’s trimmed outlook, combined with concerns about AI-led disruption and softer technology spending, fed directly into heavy selling in Indian IT names. At the same time, crude oil spikes and Middle East tensions added macro risk, while FII outflows and a weaker rupee tightened financial conditions in market pricing. With volatility rising and multiple sectors participating in the decline, the selloff reflected more than just stock-specific moves.

Conclusion

Sensex and Nifty declined as a fresh IT selloff, higher crude and geopolitical uncertainty combined with persistent foreign selling and a weaker rupee. Attention is likely to remain on global risk signals, crude prices, FII flow data, and any further clarity on US tariff policy and US-Iran developments.
