Stretch the 2026 chart out and it tells a strange story: the Nifty 50 closed at 22,620.45 on 30 September 2026, about 14.2% below its record high of 26,373.20 set on 5 January, and only about 2% above its 2 April low of 22,182.55. In between, it recovered almost the entire fall by mid-August, then gave nearly all of that recovery back over an eight-week losing streak that ran through September, the longest weekly losing run since 2001.
An investor who checked the index twice all year, once in January and once at the end of September, would see a market down roughly 14% and have no idea that it spent August within striking distance of a full recovery.
The first fall: an oil and currency shock
Three forces hit at once in early 2026, and each one amplified the others. An oil shock from the Strait of Hormuz crisis pushed Brent sharply higher, which is close to a worst case for a country importing roughly 90% of its crude. That single price move widened the trade deficit, raised inflation and put the rupee under pressure simultaneously.
The currency turned that into a selling loop. A falling rupee erodes the dollar value of Indian holdings, so foreign investors sold, which weakened the rupee further, which deepened their losses. Foreign ownership of Indian equities fell to a 14-year low earlier in the year, a slide our FPI outflows coverage has tracked throughout.
Why the Nifty recovered by August
Earnings did the work the first time. India Inc's Q1 FY27 profits grew about 2% year on year against a consensus expecting a 10% decline, and about 17% excluding oil marketing companies, with banking and financial services up roughly 20% and metals about 53%. Our Q1 FY27 earnings scorecard breaks down which sectors carried it.
That is a fundamentally different kind of rally from a liquidity-driven one. The market had priced an earnings recession that did not arrive, so the correction was a re-pricing of a forecast rather than of the businesses themselves. Foreign institutional investors briefly turned net buyers in July and August 2026, reversing the pattern that had defined the first half of the year, while domestic institutions had already built the floor underneath.
Why it fell again through September
This time the causes were almost entirely external, and they stacked up in the space of a month. 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 relative to Indian equities. Our US 10-year yield at 5% piece covers the mechanism.
Oil added a second squeeze. Brent crude spent most of September above $100 a barrel on the Strait of Hormuz standoff, before easing to about $97 by 30 September as Saudi Arabia found a way to route crude around the chokepoint, tracked on our crude oil price today page. The combination gave the Nifty its worst calendar month in 25 years, down about 6.7%, and an eight-week losing streak from 3 August to 25 September, the longest since 2001, when nine straight red weeks ran through the dot-com bust and the September 11 attacks.
Why this round trip matters for investors
The structure of Indian markets has changed in a way this whole episode makes visible. Domestic monthly SIP flows and record DII buying, Rs 64,758.56 crore in September alone, absorbed a wave of foreign selling that would have caused a disorderly crash a decade ago, which is why a second double-digit drawdown stayed orderly rather than turning into a panic. The floor is domestic, and it does not check the news before buying, a mechanism our how to read FII and DII activity piece explains.
It also shows that recoveries can be undone by a completely different set of causes than the ones that built them. The April fall was about India's own import bill and currency. The September fall was almost entirely about US interest rates and a second oil spike, which means the drivers of the next move are just as likely to come from outside India as from inside it.
What to watch from here
The most immediate thing is whether the losing streak extends to a ninth week, which would tie the 25-year record. A break in that streak, even a modest one, would be the first technical sign that the September slide is exhausted.
Watch the Reserve Bank of India's 7 October decision and the Federal Reserve's 27 to 28 October meeting. Both central banks now sit squarely between the Nifty and any sustained recovery, since a hold from both keeps the rate differential that has been pulling foreign capital away from India.
Watch whether Q2 FY27 earnings, starting with TCS on 8 October, repeat the beat that rescued the market in July. The comparison base gets harder each quarter, and this is the first quarter to carry a full period of expensive fuel and a weaker rupee in the cost line.
Risks to monitor
The second risk is that September's causes do not resolve quickly. Unlike April's oil shock, which eased within weeks once the rupee and crude stabilised, a hawkish Fed and a still-fragile Hormuz workaround could both persist through October without a clean catalyst either way.
The third is technical. A market that has fallen twice from the same record high in nine months trades differently than one testing a level for the first time, since every rally now runs into supply from investors who bought closer to 24,580 and are waiting to get back to even. This is general information, not investment advice.
Nine months, two falls, one incomplete recovery, and the index within 2% of where the worst of it started. The lesson from 2026 so far is not that markets always come back, it is that coming back is not the same as staying back.
