Eight weeks in a row does not happen often. The Nifty 50 closed lower every week from 3 August to 25 September 2026, eight consecutive losing weeks, the longest such run since 2001, when the index fell for nine straight weeks. One more losing week in the first days of October would tie that 25-year record.
What makes eight weeks unusual
A single bad week happens often. A losing streak this long has happened only once before in 25 years of Nifty data, in 2001, which is what makes the comparison worth making instead of treating this as routine market noise.
The 2001 streak needed three separate shocks landing together. The 2026 streak has needed only two, oil and US rates, running at the same time for two months without either one letting up.
Why the streak has run so long
Unlike 2001, no single event caused this one. Brent crude spent most of the eight weeks above $100 a barrel on the Strait of Hormuz standoff, before Saudi Arabia routed more crude around the chokepoint and Brent eased to about $97 by 30 September, tracked on our crude oil price today page. Costlier oil for most of two months widened India's import bill and kept the rupee under pressure the whole stretch.
The US side never eased either. The Federal Reserve raised its target range to 3.75 to 4.00% on 16 September, and the US 10-year Treasury yield touched a 19-year high near 5.1%, making dollar assets more attractive than emerging-market equities for the entire period, a mechanism our US 10-year yield at 5% piece explains.
Both pressures ran concurrently rather than in sequence, which is unusual. Most corrections have one dominant cause that eventually resolves; this one has had two independent causes overlapping for two straight months, neither of which has fully cleared even as both have eased slightly by month end.
Why it was a grind, not a crash
The streak's defining feature is its shape. A 25-year-record-adjacent losing run would normally suggest panic selling, but the Nifty never fell more than about 2% in a single session through the entire eight weeks. That is almost entirely down to who was on the other side of the trade.
Domestic institutions bought a record Rs 64,758.56 crore of Indian equities in September 2026 alone, part of 38 straight months of net buying worth Rs 20.19 lakh crore since August 2023, funded by record SIP inflows of Rs 32,297 crore in August, as our how to read FII and DII activity piece explains. Every week that foreign investors sold, domestic mutual funds absorbed most of it, turning what could have been a sharp correction into a slow, week-by-week decline instead.
What it would take to end
Streaks like this do not usually fade quietly. The 2001 nine-week streak ended only once the specific shocks behind it, the scam investigation and the dot-com unwind, worked their way through, and markets stayed weak for a long stretch afterward rather than snapping back immediately.
For 2026, the equivalent triggers are visible. A Reserve Bank of India decision on 7 October, TCS opening Q2 FY27 earnings season on 8 October, and the US Federal Reserve's 27 to 28 October meeting are the three events most likely to break the pattern in either direction, as our stock market October 2026 what to watch piece lays out.
Risks to monitor
The second risk is assuming the streak's end means a quick recovery. The 2001 precedent argues the opposite: breaking a long losing streak has historically been followed by continued weakness rather than an immediate rally, since the pressures behind a grind this long rarely disappear all at once. This is general information, not investment advice.
Eight weeks of losses with no single session doing much damage is an unusual kind of correction, patient rather than violent. Whether October adds a ninth week and a new 25-year record, or breaks the pattern instead, the answer arrives within the first seven trading days of the month.
