Sensex down 500 points: 5 reasons why stock market is falling today?

Dalal Street opened in red as the stock market once again woke up with concerns over geopolitical questions and rising crude oil prices. The Sensex tanked nearly 600 points in early trade on Wednesday, while the Nifty slipped below 23,500, before making a brief recovery.A combination of crude oil nearing $100, escalating Middle East tensions, expectations of a US rate hike, a liquidity drain towards IPOs and heavy selling in IT stocks is weighing on investor sentiment.At 9:29 am, the Sensex was down 533.48 points, or 0.71%, at 75,044.10, while the Nifty 50 declined 127.25 points, or 0.54%, to 23,507.85.Here are the key reasons behind the fall that has investors taking a cautious sentiment and markets seeing a bearish tone. BRENT CRUDE IS CLOSING IN ON $100The first and most immediate concern is oil.Brent crude was up 1.44% at $99.33 a barrel, while WTI crude rose 1.29% to $94.23. The jump follows an escalation in the Middle East, raising concerns over possible disruptions to energy supplies. This matters disproportionately for India because it is a major crude importer. Sustained higher oil prices can widen the trade deficit, increase the import bill and add to inflationary pressure.The Nifty Oil & Gas index was down 0.13% in early trade, while Reliance Industries declined 1.07%.The concern is not simply where crude is trading today. Investors are worried about what happens if prices remain close to or move above $100 for an extended period.US RATE-HIKE FEARS ARE BACKThe second pressure point is the US Federal Reserve.Stronger-than-expected US jobs data has increased expectations of a rate hike in September. Higher US interest rates can make dollar assets more attractive and tighten global financial conditions.That creates pressure on emerging markets such as India and can also hurt sectors that depend heavily on US demand.The impact is particularly visible in IT stocks, which have significant exposure to the US market.FII SELLING PICKS UPFII selling has also emerged as another pressure point for Indian equities in the last few sessions. While foreign portfolio investors had turned strong buyers in August, pouring around $3.1 billion into Indian equities, their biggest monthly inflow in nearly two years, their stance has reversed towards selling at the start of September.Across the eight sessions from August 28 to September 8 for which data is available, FIIs were net sellers to the tune of Rs 10,494.80 crore.The selling has been particularly heavy on August 28 and 31, when they offloaded Rs 5,039.80 crore and Rs 7,985.88 crore, respectively. Although FIIs returned as buyers on September 1 and 2, purchasing Rs 1,143.38 crore and Rs 6,688.37 crore, selling resumed over the following sessions.This recent FII outflow is adding to pressure on the secondary market at a time when rising crude prices, global rate concerns and the IPO boom are already competing for investor liquidity.Domestic institutional investors have provided a strong cushion, buying a cumulative Rs 30,256.71 crore over the same eight sessions, but their buying has not been enough to fully offset the negative sentiment created by renewed foreign selling.IPO BOOM IS SUCKING LIQUIDITY FROM THE SECONDARY MARKETThere is also a distinctly domestic reason for the continuing weakness.The Indian IPO market is seeing strong momentum, with investors chasing listing gains even as the Nifty's year-to-date return remains negative.Dr V K Vijayakumar, Chief Investment Strategist at Geojit Investments Limited, said two strong headwinds are currently affecting the market — crude oil near $100 and the liquidity being absorbed by IPOs."Two strong headwinds are impacting the market now. One, Brent crude around $100 amidst escalating US-Iran tensions is weighing on the economy. Two, the booming IPO market is sucking liquidity out of the market resulting in sustained downtrend in the Nifty," Vijayakumar said.He believes the IPO factor may currently be having a bigger impact than crude."Perhaps, the latter is impacting the market more than the former," he said.According to Vijayakumar, listing gains from IPOs have risen to about 22% since June, encouraging both retail and institutional investors to put money into the primary market. He said even FIIs, which have sold equity worth Rs 2.84 lakh crore through exchanges this year, have invested about Rs 36,000 crore in IPOs."Everyone is riding the momentum in the IPO market," he said.IT STOCKS ARE AMPLIFYING THE FALLThe fourth factor is the sharp sell-off in IT stocks.The Nifty IT index fell 3.06% in early trade, making it the worst-performing major sectoral index. Infosys fell 3.50%, HCL Technologies declined 3.67%, Tech Mahindra dropped 3.43% and TCS fell 2.88%.The sell-off has been intensified by the sharp fall in Coforge after its chairman Om Prakash Bhatt resigned following concerns raised by an internal audit over the company's board evaluation process.Coforge was down 5.70% in early trade.The weakness in IT is important for the benchmark indices because several large IT companies are heavyweight constituents of the Nifty and Sensex.WHAT DOES THE BROADER MARKET SAY?The fall is broad, but it is not an across-the-board panic.Nifty Midcap 50 declined 0.46%, Nifty Midcap 100 fell 0.35% and Nifty Smallcap 100 dropped 0.15%. India VIX rose 3.02% to 11.57.There are also pockets of buying. Nifty Metal gained 0.70%, Nifty Pharma rose 0.36% and Nifty Healthcare advanced 0.56%.Vijayakumar believes the current weakness could eventually create opportunities in fairly valued large-cap stocks."Investors can now accumulate fairly-valued stocks, particularly large-caps in growth sectors," he said.He also cautioned investors against blindly chasing IPOs."Discretionary is the better part of FOMO," Vijayakumar said.For now, the market's direction will depend heavily on whether crude can move away from the $100 level, how the Middle East conflict develops and whether expectations of a US rate hike strengthen further.- EndsPublished On: Sep 9, 2026 10:03 IST
