Sensex nosedives 2,500 pts; Nifty tumbles 3% to 23,000 - five key reasons behind Thursday’s market rout

The Indian equity market witnessed sharp selling on Thursday, logging its steepest single-day decline since April 7, 2025, amid escalating Iran-Israel tensions, elevated crude prices, and a hawkish U.S. Federal Reserve stance.

Snapping a three-session gaining streak, benchmark indices plunged up to 3.5%, with the Nifty slipping below the 23,000 mark and the Sensex falling under the 74,000 level. The 30-share Sensex settled at 74,207.24, down 2,497 points, while the Nifty50 declined 776 points, or 3.26%, to close at 23,002.

In the preceding three sessions, the Sensex and Nifty50 had gained over 2,100 and 600 points, respectively, adding nearly ₹9.5 lakh crore to investor wealth.

Broader markets also came under pressure, with the Nifty MidCap and Nifty SmallCap indices falling 3.2% and 2.9%, respectively.

Investors lost over ₹11 lakh crore in a single session, as the total market capitalisation of BSE-listed firms declined to ₹427.5 lakh crore from ₹438.6 lakh crore in the previous session.

Five headwinds behind Thursday’s market sell-off:

Crude spike rattles markets

The market sell-off was mainly triggered by sharp spike in crude prices following Israel’s strike on Iran’s largest LNG facility. Brent crude, the global benchmark, surged as much as 8.5% to $116 per barrel on Thursday after Iran struck key energy installations across the Gulf, in retaliation for an earlier Israeli attack on its South Pars gas field.

The last time Brent traded at these levels was in March 2022, when it touched $117.25 following the outbreak of the Russia-Ukraine conflict.

For India, a major oil importer, a sustained rise in crude prices carries significant macro and market implications. Higher oil prices typically widen the import bill, fuel inflationary pressures, and weigh on corporate earnings.

Hawkish Fed stance

The sentiment was further dented after the U.S. Federal Reserve held rates steady while signalling a mildly hawkish stance. In an overnight move, the central bank kept benchmark interest rates unchanged at 3.5%-3.75% for the second consecutive meeting in March 2026, with an 11–1 vote.

“The Fed’s decision to pause, along with elevated inflation projections and rising geopolitical tensions, reinforces a ‘higher-for-longer’ rate cycle than markets had anticipated,” said Rajesh Palviya, Head of Research at Axis Securities.

Ankita Pathak, Head – Global Investments at Ionic Asset, said the “mildly restrictive” stance appears appropriate for now. The dot plot remained unchanged, signalling one rate cut each in 2026 and 2027. She added that the pause limits dollar weakness, weighing on emerging markets already grappling with higher energy prices and currency pressures. The RBI, she noted, may also face a similar dilemma, reducing the likelihood of a rate cut in April.

Broad-based sell-off across sectors

The sell-off was broad-based, with all sectoral indices ending in negative territory. Rate-sensitive sectors bore the brunt of the decline, as the Nifty Auto, Nifty Private Bank, and Nifty Realty indices fell 3–4%.

The Nifty IT index dropped over 3%, extending its downtrend amid global growth concerns, while defensive segments such as Nifty FMCG and Nifty Pharma declined more than 2%.

On the BSE Sensex, all 30 constituents closed in the red, led by Eternal , Bajaj Finance , M&M , and HDFC Bank , each falling over 5%. HDFC Bank shares came under pressure after its part-time chairman and independent director, Atanu Chakraborty, resigned with immediate effect on Wednesday.

IT majors, including TCS , Infosys , and HCLTech, remained weak on persistent global growth worries. The sell-off was not limited to cyclicals, with defensives such as ITC and Hindustan Unilever also trading lower.

Among the few relative outperformers were power and utility stocks like Power Grid Corporation of India and NTPC, which saw relatively limited declines.

Rupee slump fuels macro concerns

Market sentiment was further weighed down by the sharp depreciation in the Indian rupee, which hit a fresh all-time low on Thursday. The currency slipped to ₹92.63 per U.S. dollar on March 19, breaching its previous record low of ₹92.48 in the previous session, as escalating Middle East tensions kept oil prices elevated, triggering capital outflows and heightening macroeconomic risks for Asia’s third-largest economy.

Foreign institutional investor (FII) outflows continued to weigh on the rupee, with net equity sales of ₹73,704.31 crore so far in March - the highest since October 2024.

In contrast, domestic institutional investors (DIIs) have been absorbing the selling pressure, purchasing ₹94,828 crore worth of equities month-to-date. They have remained net buyers in every session, helping cushion the markets and limit sharper declines despite persistent foreign outflows.

Escalating Middle East conflict 

The ongoing conflict involving the United States, Israel, and Iran has entered its 20th day, escalating into what analysts describe as a “total energy war,” with retaliatory strikes targeting critical energy infrastructure across the Gulf region.

The escalation has severely disrupted shipping through the Strait of Hormuz, a key global energy chokepoint, effectively halting or sharply reducing tanker movement. The waterway typically handles around 20% of the world’s oil supply and a significant share of global LNG shipments, making markets highly sensitive to any disruption.
