Why the Indian Market Fell for Seven Straight Weeks (September 2026)

The Nifty 50 has now fallen for seven weeks in a row. The last time it did that was the Covid-19 crash of 2020.

That sounds alarming, and the headline stat is real. But the more useful story is hiding underneath it: over those same seven weeks, the index lost only about 5.8%. A seven-week foreign-selling streak that would once have gutted the market produced a slow bleed instead. Understanding why is the difference between panicking at a headline and reading what the market is actually doing.

What actually happened this week?

The Nifty closed Friday, 25 September, at 23,140.50 — down 205.90 points from 23,346.40 a week earlier, per Business Standard. It was the seventh straight weekly decline, the index's longest losing run since the pandemic crash of February-April 2020, when it also fell for seven consecutive weeks.

The week was not a straight line down. The Nifty actually climbed to 23,414.30 on Monday, then gave all of it back and more. Thursday was the worst session — the Nifty fell 1.64% and the Sensex 1.67% — before Friday clawed back a little, with the Sensex adding 315.20 points (0.43%) to 73,895.74 and the Nifty adding 77.40 points (0.34%).

Zoom out and the damage is contained but real: the Nifty is now 12.3% below its 52-week high of 26,373.20, and about 5.8% below where it stood seven weeks ago.

Why did it fall? Three pressures, one theme

The proximate reasons changed by the day, but they share a theme: the price of money went up, and India doesn't set that price.

US bond yields. The single biggest driver, according to Piper Serica's Abhay Agarwal, was a spike in US Treasury yields — the 10-year and 30-year touched 5.18% and 5.35% this week. "The last time the 10-year yields were at this level were in 2007," he told Business Standard. When a risk-free US government bond pays more than 5%, global money has less reason to take a chance on emerging-market equities. India becomes, in Agarwal's words, "collateral damage."

Crude's round trip. Oil is India's chronic pressure point, since the country imports most of the crude it burns. Brent touched $106 a barrel mid-week on geopolitical fear before falling hard — down 11.5% over the full week to $98.59. The volatility itself, more than the closing level, kept nerves frayed.

The rupee and domestic yields. India's own 10-year government bond yield rose to 7.119%, now up 62 basis points over the past year. The rupee slipped to 95.82 per dollar. Neither moved violently, but both point the same way: tighter financial conditions, imported from abroad.

The real story: a tug-of-war between two kinds of money

Here is the part most headlines skip. A market falls when sellers overwhelm buyers — but this market had a very large, very determined buyer on the other side of the foreign selling.

Foreign institutional investors (FIIs) were the sellers. They net sold ₹11,490 crore of Indian shares between 21 and 25 September, offloading stock in four of the five sessions. For the month to 25 September, they had pulled out roughly ₹18,531 crore.

Domestic institutional investors (DIIs) — India's mutual funds, insurers and pension money — were the buyers. They net bought ₹16,398 crore over the same week, buying every single session. For the month, they had absorbed roughly ₹52,617 crore.

Read those two September numbers together: domestic institutions bought almost three times what foreigners sold. That is the tug-of-war holding the floor. It is also why seven weeks of foreign outflows translated into a 5.8% dip rather than a crash.

Why this matters more than the streak

For most of the Indian market's history, foreign money set the tone. When FIIs sold, the market fell, because there was no one big enough to catch it. What has changed — and this week is a clean illustration — is that domestic institutional flows, fed largely by monthly SIP contributions from ordinary investors, have grown into a counterweight big enough to absorb sustained foreign selling.

That does not make the market safe. It means the market's shock absorber has changed. If foreign selling accelerates, the question is no longer "will FIIs sell?" but "will domestic inflows keep showing up to buy?" So far in this streak, they have.

It is worth naming what individual stocks did only as context, not as calls. Insurance-linked stocks fell sharply this week after the IRDAI signalled a consultation paper on distribution commissions; separately, several Tata group companies moved on a governance vote at Tata Sons. Both are reported facts about specific companies. Neither is a recommendation, and neither is why the index fell — the index fell on the price of money.

What are analysts watching next?

Technical analysts quoted by the Sunday Guardian are watching 23,000 as a support level and 23,200 as near-term resistance, with the index closing Friday right between them at 23,140.50. Those are levels people are watching, not predictions, and certainly not instructions.

The honest read: the direction from here depends on things India does not control — US Treasury yields, crude, and whether foreign selling moderates. The one domestic variable that has mattered most is whether SIP-fed domestic buying keeps absorbing the outflows. This is a market map, not a recommendation.

Frequently asked questions

Is a seven-week losing streak a crash? No. A crash is a sharp, fast drop. This is a slow grind — about 5.8% over seven weeks. It is notable because of its length (the longest since 2020), not its depth. The Nifty is roughly 12% off its 52-week high, which is a correction, not a collapse.

What are FIIs and DIIs? FIIs are foreign institutional investors — overseas funds buying Indian stocks. DIIs are domestic institutional investors — Indian mutual funds, insurers and pension funds. In September 2026, FIIs were net sellers and DIIs were net buyers, and the DIIs bought far more than the FIIs sold.

Why do US bond yields hurt Indian stocks? When US government bonds pay more than 5%, global investors can earn a solid, low-risk return in dollars. That pulls money out of riskier markets like Indian equities. India does not set US yields, so it absorbs the effect without controlling the cause.
