Why Indian Stocks Fell on 28 September

Indian equities fell sharply on Monday, 28 September 2026, extending a seven-week losing run. The decline matters to a regular investor because it reduced the market value of broad equity holdings in a single session, with losses spread across large, mid- and small-cap stocks rather than confined to a few names.

At the close of trading on 28 September, the BSE Sensex was down 1,124.02 points, or 1.52%, at 72,771.72. The NSE Nifty 50 was down 360.25 points, or 1.56%, at 22,780.25. Both closing levels were reported after the end of the session and were described in contemporaneous reporting as the lowest closes in nearly six months. During the session the Nifty traded below 22,800, and one report of intraday data put the Sensex day low at 72,716.23 and the Nifty day low at 22,762.20. Broader indices also fell: the Nifty midcap index declined about 1.6% and the smallcap index about 1.8%. Market volatility rose, with the India VIX, a gauge of expected near-term market fluctuation, up about 12.5% on the day.

The immediate backdrop was a rise in crude oil prices after hopes of a near-term diplomatic easing in West Asia faded. Reporting on the session linked the selling to the rejection by the United States President of an Iranian proposal involving a short ceasefire and reopening of the Strait of Hormuz, a narrow waterway through which a large share of seaborne oil moves. Brent crude was reported at over 108 dollars per barrel on 28 September, up more than 3% on the day. For India, the third-largest crude importer in the world, higher crude can raise fuel and transport costs, widen the import bill, pressure the rupee and feed inflation expectations. The rupee closed at 95.98 per dollar on 28 September, 16 paise weaker than the previous close of 95.82.

A second channel was bond yields. Yields on long-term United States government bonds were reported above 5.2%, the highest since 2004, while the yield on the Indian benchmark bond reached 7.18% during the session, the highest since April 2024. A bond yield is the annual return an investor earns for holding the bond at its current price. When yields rise, future company earnings are discounted more heavily in valuation arithmetic, and interest-bearing assets can look relatively more attractive than equities. Both effects can weigh on share prices even when a company's current sales have not changed.

A third channel was foreign investor selling. Reports on the session said foreign investors had sold about 2.2 billion dollars of Indian shares so far in September, after being net buyers in July and August. Sales by large foreign institutions increase the supply of shares offered in the market and can amplify a fall that begins for other reasons. Analysts quoted in the reporting also pointed to liquidity being absorbed by a busy September market for new listings.

The selling was broad. Of the 50 Nifty constituents, 47 closed lower. The largest Nifty declines included Jio Financial, Tata Motors Passenger Vehicles, Larsen and Toubro, Adani Enterprises and Adani Ports. The few gainers included Dr Reddy's Laboratories, Infosys and Tech Mahindra. All sectoral indices closed lower, with the PSU bank index down about 3% and telecom down about 2.3%, while energy, infrastructure, consumer goods, private banks, metals and oil and gas each fell more than 1%.

What is confirmed and what is uncertain

The closing levels, percentage changes and breadth of the fall are confirmed by more than one contemporaneous market report. What is less certain is how much each cited factor contributed. Market reports attribute the fall to crude, yields, foreign selling and geopolitical uncertainty, largely on the basis of analyst commentary and the timing of events. That is a plausible causal account, not a measured decomposition. The course of crude prices, the Strait of Hormuz position, bond yields and foreign flows can each change quickly, and broker views quoted for 29 September are short-term technical assessments, not settled forecasts.
