The Sensex plunged 1,247.71 points on September 24, 2026, as rising US Treasury yields, crude oil prices above $100 a barrel and renewed concerns over interest rates triggered heavy selling across Indian equities. The Nifty 50 also fell sharply, ending below the 23,100 mark.
Sensex Ends 1.67% Lower, Nifty Falls 1.64%
The Indian stock market came under intense selling pressure on Thursday, with the Sensex closing at 73,580.54, down 1,247.71 points or 1.67%. The Nifty 50 ended at 23,063.10, declining 383.70 points or 1.64%.
The fall pushed both benchmark indices to multi-month lows. The Nifty breached 23,100 during the session for the first time since June 11, highlighting the scale of the day’s selling pressure.
The weakness was not limited to a handful of large companies. Selling extended across broader market segments, with mid-cap and small-cap stocks also coming under pressure. The India VIX, which tracks expected market volatility, rose sharply during the session as investors responded to increased uncertainty.
The decline followed a positive session on Wednesday, when the Sensex had gained 299.17 points and the Nifty rose 117.80 points. The reversal showed how quickly sentiment changed as global macroeconomic signals deteriorated.
US Bond Yields Rise to Multi-Year Highs
One of the biggest triggers for the Sensex fall was the sharp rise in US Treasury yields.
The US 10-year Treasury yield moved above 5.10% and was reported at around 5.11% to 5.14% during the market cycle. Reports said the yield reached its highest level since 2007, increasing pressure on global equity valuations.
Higher bond yields can make fixed-income investments relatively more attractive compared with equities, particularly when investors are already concerned about economic growth and inflation. They also increase the discount rate used to value future corporate earnings, which can put pressure on stock valuations.
The latest move was linked partly to stronger US business activity. Stronger economic data increased expectations that inflationary pressures could remain elevated and that the US Federal Reserve may need to keep monetary policy tighter for longer or consider another rate increase.
That shift in expectations affected markets beyond the United States. Asian equities also traded lower, adding to the negative global backdrop for Indian stocks.
Crude Oil Crosses $100 as Geopolitical Risks Persist
Crude oil was another major pressure point for Indian markets.
Brent crude moved above $100 a barrel and reached around $105 during Thursday’s trading cycle, after rising sharply in the previous session. The move came amid continuing uncertainty surrounding the US-Iran conflict and diplomatic efforts involving the two countries.
Higher crude prices are particularly important for India because the country depends heavily on imported oil. An increase in global crude prices can raise India’s import bill and put pressure on inflation, the current account and the rupee.
For companies, expensive crude can also increase operating costs. Airlines, transport companies, logistics businesses and several manufacturing sectors can be affected directly or indirectly when energy costs rise.
The combination of higher oil prices and higher US bond yields therefore created a difficult environment for Indian equities. Investors had to assess both the potential impact on corporate earnings and the possibility of tighter global monetary conditions.
Financial and Insurance Stocks Face Heavy Selling
Financial stocks were among the major casualties of Thursday’s sell-off.
Banks, NBFCs and other financial companies faced broad-based selling as investors reduced exposure to risk-sensitive sectors. Bajaj Finance was reported as one of the biggest drags on the Sensex, with its shares falling more than 5% during the session.
Insurance stocks faced an additional domestic trigger after the Insurance Regulatory and Development Authority of India, or IRDAI, released a consultation paper proposing changes to insurance distribution economics.
The proposed framework covers areas including commissions, distribution expenses, transparency and market conduct. It also proposes changes to the existing Expense of Management framework and seeks to address practices described by the regulator as dark patterns on insurance websites.
Shares of PB Fintech and other insurance-related companies came under particularly strong pressure. This meant that financial stocks were dealing with both global macroeconomic pressure and sector-specific regulatory concerns on the same trading day.
Foreign Investor Selling Adds to Market Pressure
Foreign investor flows have also remained an important concern for Indian equities.
Foreign institutional investors bought shares worth ₹1,617.45 crore on Wednesday, while domestic institutional investors bought ₹2,341.46 crore, according to data cited by market reports. However, foreign investors had remained net sellers through much of September.
Reports indicated that foreign investors had sold nearly ₹20,000 crore worth of Indian equities during September by the time of the latest data. The combination of high US yields, expensive crude, currency concerns and global uncertainty has contributed to caution among international investors.
When global yields rise, emerging-market equities can face additional pressure because investors reassess the relative attractiveness of developed-market assets. Currency movements can further influence returns for overseas investors.
For India, this means the direction of foreign flows could remain an important factor for market sentiment alongside domestic earnings and economic data.
Rupee and Interest Rate Concerns Add Another Layer
The rise in crude oil prices is also important for the Indian rupee.
India’s dependence on imported energy means a sustained increase in crude prices can increase demand for US dollars to pay for imports. A weaker rupee can, in turn, make imported commodities more expensive and add to inflationary pressure.
Recent market commentary has also pointed to pressure in India’s bond market. The 10-year Indian government bond yield had risen for several consecutive weeks, while traders were watching liquidity conditions and the possibility of future policy changes.
This creates a complicated backdrop for equities. Investors are simultaneously watching crude prices, domestic inflation, currency movements, global bond yields and central-bank policy expectations.
What Investors Will Watch Next
The immediate focus for Indian markets is likely to remain on crude oil, US Treasury yields and global monetary policy expectations.
Any further rise in oil prices could increase concerns about inflation and India’s external balance. Similarly, another move higher in US Treasury yields could keep pressure on emerging-market equities.
Investors will also watch whether foreign selling continues and whether domestic institutional buying can absorb some of the pressure.
The domestic regulatory developments around insurance distribution will remain relevant for financial stocks as well. Since the IRDAI proposals are part of a consultation process, their eventual impact will depend on the final framework and implementation.
For now, Thursday’s session shows how several global and domestic factors can combine to produce a sharp market move within a single trading day.

FAQ
Why did the Sensex fall on September 24, 2026?
The Sensex fell sharply because of a combination of higher US Treasury yields, rising crude oil prices, concerns about further interest rate increases and weak global market cues. Domestic selling in financial and insurance stocks added to the pressure.
How much did the Sensex fall today?
The Sensex closed at 73,580.54 on September 24, 2026, down 1,247.71 points or 1.67% from the previous close.
Why do higher crude oil prices affect Indian stocks?
India imports a large share of its crude oil requirements. Higher global oil prices can increase the country’s import bill and create inflationary pressure. They can also raise costs for businesses that depend heavily on fuel and transportation.
Why are US bond yields important for Indian investors?
Higher US Treasury yields can make US fixed-income assets more attractive relative to riskier assets elsewhere. They can also increase global borrowing costs and put pressure on equity valuations, particularly in emerging markets. The latest rise in US yields was one of the key factors behind Thursday’s sell-off.
