Sensex, Nifty slump as crude hits $120 on US-Iran tensions

What drove the latest selloff

Indian equities saw sharp, repeated bouts of selling as renewed tensions involving the US and Iran coincided with a fresh spike in crude oil prices. The pressure showed up quickly in the benchmarks, with traders tracking crude moves, weak global cues, and foreign selling. The risk-off mood also reflected worries around inflation in an oil-importing economy like India when energy prices jump sharply. In several sessions described in market updates, banking stocks and other index heavyweights were repeatedly cited as key drags.

The market tone remained cautious as investors weighed geopolitical headlines and the knock-on impact on input costs, the rupee, and corporate margins. In parallel, a Reuters report also pointed to a downturn in broader Asian markets and a selloff in technology, semiconductor, and AI-linked stocks adding to the negative sentiment. Another layer of uncertainty came from growing expectations that US rates could rise by end-2026, following a stronger-than-expected May jobs report.

Wednesday: Sensex and Nifty fall sharply intraday

On Wednesday, benchmark indices opened sharply lower and extended losses early in the session. The BSE Sensex fell over 680 points to an intraday low of 77,498.70 from the previous close. The Nifty 50 declined more than 200 points to 24,189.20.

By 12:33 pm, the Sensex was down 662.01 points, or 0.85%, at 77,518.71. The Nifty 50 was down 203.75 points, or 0.84%, at 24,194.95. Sudeep Shah, Head of Technical and Derivatives Research at SBI Securities, said the benchmarks opened with a sharp gap-down on reports of geopolitical tensions between the US and Iran and a spike in Brent crude prices, while the Nifty later stabilised and traded in a narrow range.

Sector check: oil and gas, FMCG among top drags

Sectoral breadth was weak on Wednesday. All indices except realty, metal, and pharma traded in negative territory. Oil and gas and FMCG stocks led the losses.

In other market commentary included in the updates, oil and gas names were also described as top losers on a down day, reinforcing how energy-linked volatility was influencing sector leadership. Select pockets such as realty and IT were referenced as gaining in one of the sessions, but the broader tone stayed cautious.

Monday (Reuters): Asia weak, crude jumps, India stocks slide

A Reuters report dated June 8 said Indian stocks declined on Monday after a significant downturn in Asian markets, while crude oil prices surged as conflict in the Middle East intensified. Rajesh Palviya, Head of Research at Axis Direct, said sentiment was dampened by a notable selloff in technology, semiconductor, and AI-related stocks, compounded by rising crude prices amid Middle East turmoil.

The same Reuters report added that expectations of a US interest rate increase by the end of 2026, following a stronger-than-expected May jobs report, also weighed on markets.

Monday levels: benchmarks lower, Nifty losers highlighted

In the latest market update for that Monday session, the Nifty50 was down 137.00 points, or 0.57%, at 23,765.60. The Sensex fell 340.68 points, or 0.45%, to 75,527.12.

Eicher Motors, InterGlobe Aviation, and Oil & Natural Gas Corporation were listed as the top losers in the Nifty 50 index. Separately, another update said the Sensex dropped over 1,000 points to 76,323 while the Nifty 50 fell 303 points to 23,873 in the morning. That note added that all sectoral indices were in the red, with Nifty Consumer Durables leading losses with a 3% drop.

Tuesday: Strait of Hormuz headlines and Brent near $113

On Tuesday, equities opened subdued as renewed hostilities in the Strait of Hormuz and a spike in Brent crude to around $113 hit sentiment. In early trade, the Sensex fell as much as 524 points, or 0.67%, to 76,745. The Nifty slipped 170 points, or 0.7%, to a low of 23,949.

The update also noted selling pressure in financial heavyweights, even as there was selective buying in IT and telecom stocks. The overall message from the session was that crude and geopolitics were overpowering domestic optimism.

Thursday: foreign selling, banks and crude keep pressure on

By Thursday, the weakness extended, with higher crude prices, foreign selling, and weak banking stocks cited as key reasons for the slide. Around 12:47 pm, the Sensex was down 585.76 points, or 0.75%, at 77,258.76. The Nifty50 fell 166.35 points, or 0.68%, to 24,160.30.

The updates also said heavyweight financial stocks stayed under pressure amid sustained foreign portfolio investor (FPI) selling and concerns around earnings growth. Reuters was cited as noting that higher crude following renewed US-Iran tensions hurt sentiment globally, especially in oil-importing economies like India.

Close and opening cues: crude at $120, rupee worries, GIFT Nifty

Markets later closed lower on Thursday with high crude prices and a weak rupee weighing on sentiment. The Sensex fell 582.86 points, or 0.75%, to close at 76,913.50, while the Nifty 50 declined 180.10 points, or 0.74%, to 23,997.55.

A sectoral snapshot in the same set of updates showed Nifty Metal down 2.12%, PSU Bank down 1.68%, Realty down 1.50%, FMCG down 1.35%, and Financial Services down 1.07%. The Oil and Gas index was also down 0.63%.

Another note said India’s benchmarks opened lower than Wednesday’s close as oil surged, with the Sensex down 1.17% at 76,578.87 and the Nifty down 1.16% at 23,898.70 at 9:23 am. GIFT Nifty futures traded at 24,119.50 at 8:11 am, indicating a lower open versus Wednesday’s close of 24,177.65. Brent crude was reported to have spiked to $120 per barrel after US President Donald Trump discussed with oil companies measures to mitigate the impact of an extended blockade at Iran’s ports, raising fears of supply disruption.

Key market levels at a glance

Why crude and geopolitics matter for Indian equities

For Indian markets, sharp jumps in Brent tend to feed into inflation expectations and can influence currency sentiment, especially when risk appetite is already fragile. The updates explicitly highlighted inflation risks for India as the world’s third-largest oil importer, along with potential pressure on economic growth and corporate earnings when crude spikes.

The market action across sessions also showed how multiple factors can stack up at once: geopolitical headlines lifting crude, weak global cues hitting risk assets, foreign outflows weighing on financials, and sector rotations that leave only a few pockets in the green. Even on sessions where the benchmarks steadied after a gap-down, traders remained focused on whether crude would stay elevated and whether banking-heavy indices would see sustained selling.

What to watch next

In the near term, traders are likely to keep tracking developments around US-Iran tensions and the effect on crude prices, alongside foreign investor positioning and bank stock performance. Updates also flagged caution ahead of key quarterly results and ongoing sensitivity to global macro signals, including US rate expectations.

If crude remains volatile, intraday swings may continue to be driven more by global cues than by domestic headlines, as shown by the repeated link between oil spikes and benchmark declines across the sessions described above.
