Summary
The Sensex crashed 1,247.71 points to close at 73,580.54 while the Nifty 50 fell 383.70 points to end at 23,063.10 on Thursday, 24 September 2026, with the Nifty breaching 23,100 for the first time since 11 June as weak global cues and a regulatory shock to financial stocks triggered selling across every sector.
All sectoral indices ended in the red, with Nifty Private Bank falling 2.2% and Metal declining 1.9%, while Bajaj Finance, HDFC Life, Bajaj Finserv, Axis Bank and InterGlobe Aviation led the Nifty losers and only Cipla and NTPC gained.
PB Fintech crashed 34% and financial stocks lost a combined ₹1 lakh crore in market value after the insurance regulator proposed capping distributor commissions, while the NSE itself made a quiet but historic debut to become India’s 10th most valued company.
US Treasury yields at their highest since 2007 and crude’s surge to $105 set the weak global backdrop, though Brent eased to $102.24 on Thursday morning as Iran signalled a preference for diplomacy.
The Sensex fell 1,247.71 points, or 1.67%, to close at 73,580.54, while the Nifty 50 ended 383.70 points, or 1.64%, lower at 23,063.10, after touching an intraday low of 23,046.15 that breached its 11 June low of 23,072.
The broader market fell harder than the benchmarks. The Nifty MidCap dropped 2% and the Nifty SmallCap declined 1.5%, while the rupee weakened for a second day, falling 22 paise to 95.96 per dollar.
Impact on the stock market
Sectoral losers: every sectoral index closed in the red, with financial services the hardest hit as the insurance commission proposals landed, followed by metals unwinding Wednesday’s rally.
Amid the wreckage, more than 120 stocks still touched 52-week highs, including Caplin Labs, Shyam Metalics, Laurus Labs and Aurobindo Pharma, showing pockets of strength beneath the index-level pain.

Market aftermath: Impact on stocks
PB Fintech: A 34% Crash That Wiped Out ₹30,000 Crore in a Day
PB Fintech, the operator of Policybazaar, suffered one of the most brutal single-day falls in recent memory, crashing 34% to ₹1,244.5, its lowest level since March 2025, and erasing ₹30,000 crore of market value in one session. The trigger was the insurance regulator’s consultation paper proposing commission limits for distributors, linked to the complexity of sales and service, which lands hardest on a business built around insurance distribution. The violence of the move was captured in the derivatives market, where the September 1600 put contract turned a ₹20,000 position into roughly ₹75 lakh in a single day.
Brokerage reaction was unusually blunt, with Bernstein calling the proposed cuts “ugly” and saying the company’s unit economics “unravels” at the proposed take rates, since call centre costs do not hold up at those levels. Jefferies estimated that a 10% cut in commission rates could translate into a 10-12% earnings decline for PB Fintech and Turtlemint, while Emkay flagged sharp cuts across health renewals, first-year term life and motor commissions. With the draft also closing advisory fee and marketing expense routes, Bernstein said the company “will need to find solutions”, which is about as direct as brokerage language gets.
Banks and NBFCs: A ₹1 Lakh Crore Hit as the Commission Caps Reach the Lenders
The pain spread well beyond insurance platforms, because banks and non-bank lenders earn substantial fees from distributing insurance products, and 12 financial stocks lost a combined ₹1 lakh crore in market value. L&T Finance fell 10% to a three-month low of ₹279, Max Financial Services slumped over 10% to a one-year low of ₹1,360.10 given its reliance on bank-sold products, Axis Bank dropped more than 4.5%, and Bajaj Finance and Bajaj Finserv were among the top Nifty laggards. The proposals would reintroduce commission caps across life, health and motor insurance that were scrapped in 2023, bar lenders from compulsorily bundling insurance with loans, and stagger life commissions over the life of a policy instead of paying them largely upfront.
The rules would apply prospectively from FY28, with public feedback open over the next month, so nothing is final yet. Jefferies noted the exposure varies widely, with IndusInd Bank and IDFC First Bank carrying higher risk to their fee income while ICICI Bank and PSU banks are less affected. Technically, analysts see immediate support for the Bank Nifty at 56,000-55,700, with a decisive break below opening the door to 55,200 and then 54,800.
The Capex Story: Private Companies Now Drive 90% of New Project Announcements
Away from the selloff, HSBC released a report showing India’s investment cycle is quietly changing character, with private companies accounting for 90% of new project announcements in the June quarter. New announcements rose 28% year-on-year to ₹14.6 trillion, with nuclear projects and data centres contributing around 80% of the value and a similar share concentrated in Maharashtra. Government spending remains the base, with central capex up 30% in the fiscal year to July, including 41% growth in both defence and roads.
HSBC did add execution caveats, noting that projects under implementation grew only 5%, completions fell 17%, and shelved projects jumped around 600%, mainly due to three large railway projects being put on hold. The bank remains constructive on companies exposed to domestic capex, naming manufacturing, renewables, power transmission and data centres as the structural themes, while favouring firms with strong order books and limited input-cost exposure. On a day when financials dragged the index down, the report is a useful reminder of where the long-term growth engines are still running.
Crude Oil: Brent Eases to $102 as Iran Signals a Preference for Diplomacy
Crude cooled slightly on Thursday morning after its recent rebound, with November Brent futures down 0.81% to $102.24, WTI declining 0.77% to $91.45, and October crude futures on the MCX easing 0.43% to ₹8,787. The trigger was a report quoting an Iranian official saying that while Iran and the US remain divided, diplomacy must continue, with Tehran reviewing the US response to its peace proposals that prioritise lifting the naval blockade and reopening the Strait of Hormuz. The rhetoric stayed sharp, though, with President Masoud Pezeshkian telling the UN General Assembly that Iran would not bow to threats and would not allow free navigation through Hormuz while sanctions and the blockade remain.
Supply data leaned mildly bearish, with US crude inventories rising 3 million barrels to 426.4 million barrels, about 2% above the five-year average. Even so, crude’s earlier surge back towards $105 was part of Thursday’s weak global backdrop for equities, alongside the US benchmark Treasury yield climbing to its highest level since 2007. The oil relief trade of recent sessions has clearly not been a straight line.
Conclusion
Thursday was the sharpest reality check of the month, with a 1,248-point Sensex fall, the Nifty below its June low, and a regulatory draft doing damage that no geopolitical headline managed this week. The irony is hard to miss, since the same commission overhaul that insurance stocks rallied on last week has now wiped ₹1 lakh crore off financials once the fine print showed distributors and banks bearing the cost. Chart watchers see the market on the verge of a breakdown, with a decisive move below 23,000 risking a slide towards 22,600, and any bounce facing resistance near 23,300. With the IRDAI consultation open for a month, Iran talking diplomacy while holding Hormuz shut, and the NSE’s own listing giving the market a new heavyweight, the next few sessions will decide whether 23,000 holds or the correction deepens.
