Although India’s economy expanded by 7.8% between April and June, the Nifty 50 still tumbled 6.1% in September, recording its worst monthly performance since March. This contrast highlights the central question for October: Can robust domestic growth offset headwinds from foreign selling, a strengthening dollar, and high oil prices?
Where the Market Stands
At the close of September 30, the Sensex finished at 72,480.29 while the Nifty ended at 22,620.45. The Sensex dropped 5.8% over the month, marking its second consecutive monthly decline. Currently, the Nifty sits roughly 14% beneath its 52-week peak of 26,373, with 40 out of 50 constituent stocks closing the month in the red. On September 29, banking, IT, and auto sectors suffered the heaviest losses, whereas metals and pharmaceuticals showed resilience.
Why Foreign Money is Leaving
Foreign investors sold USD 2.7 billion of Indian shares throughout September, bringing total net sales for the year to USD 26.8 billion. External factors drive much of this pressure; global central banks, including the US Federal Reserve, implemented rate hikes in September. These elevated rates make developed-market bonds and dollar assets more appealing than emerging-market equities.
Additional strain comes from the rupee, which weakened past 96 per dollar in September, nearing its May record low of 96.96. The RBI intervened to curb the depreciation. Because a weaker rupee diminishes the dollar-denominated value of foreign holdings upon conversion, Indian shares can lose attractiveness even amid healthy corporate performance.
Crude oil compounds these challenges. Because India imports the vast majority of its crude, Brent crude hovering near USD 100 a barrel in recent weeks widens the import bill, drives inflation, and further burdens the rupee.
Domestic institutional funds provided a cushion by stepping in to absorb a portion of the sell-off. While market commentary has highlighted softer railway freight and slowing auto sales, outside forces account for the bulk of the decline. Financial flows can shift quickly, whereas an internal economic slowdown would require more time to fix.
RBI Policy and Inflation
The RBI has held its repo rate steady at 5.25% across four consecutive meetings, with the next announcement scheduled for October 7. Back in August, the central bank upgraded its growth projection for the fiscal year ending March 2027 to 6.7%. Meanwhile, retail inflation climbed to 4.82% in August—its peak level since December 2024—with the RBI anticipating that consumer prices will peak during the October-to-December quarter.
The central bank currently navigates a complex mix of rapid growth, climbing inflation, and a sliding currency. ICRA has warned of a potential rate hike prior to December. Consequently, rate-sensitive equities and bank stocks face the highest exposure to the central bank’s stance, meaning the tone of the RBI’s statement may carry more weight than the actual rate decision.
Earnings Face a Tougher Test
Second-quarter financial results kick off with TCS, followed closely by Infosys and HCL Tech. IT equities head into this reporting cycle under intense pressure, evidenced by an 11% drop in the Nifty IT index through September driven by concerns over US client budgets.
Brokerage firm Kotak anticipates a subdued quarter, projecting a modest 2.8% year-over-year revenue increase for TCS. Although a softer rupee typically benefits IT exporters, Kotak notes that sluggish revenue growth will likely neutralize that advantage.
Broader market forecasts peg profit growth between 13% and 14%, down from the 18% to 19% registered in the first quarter. This deceleration stems from compressed margins, rising expenses, and rigorous year-ago benchmarks. With crude oil prices remaining elevated, commentary regarding operating costs will be critical. Furthermore, shifts in forward-looking earnings projections can influence market valuations more heavily than the most recent growth numbers. These upcoming results will determine whether recent market weakness is broadening.

FAQs
1. Why did the Nifty fall in September despite 7.8% GDP growth?
Pressure came largely from outside India. Foreign investors sold USD 2.7 billion of shares, global central banks raised rates, the rupee slipped past 96 per dollar, and Brent crude stayed near USD 100. Strong growth did not offset these forces, and the Nifty lost 6.1% for the month.
2. How does a weak rupee hurt Indian shares?
A falling rupee cuts the dollar value of foreign holdings when converted back into dollars. That lowers the appeal of Indian stocks for overseas investors, even when company results look healthy. It also raises the import bill, adding to inflation.
3. What should investors expect from the RBI’s October 7 decision?
The RBI has held the repo rate at 5.25% for four straight meetings, while August inflation hit 4.82%, its highest since December 2024. The central bank faces growth, rising prices and a weak rupee together. ICRA has flagged a possible hike before December, and the tone of the statement may matter more than the decision itself.
4. Why are IT stocks under the most pressure this earnings season?
The Nifty IT index fell over 11% in September on worries about US client spending. Kotak expects TCS revenue to rise just 2.8% year on year, and weak growth may cancel the usual benefit of a weaker rupee. TCS reports on October 8, followed by HCL Tech and Infosys.
5. Which indicators matter most for markets in October?
Five items deserve close attention: Brent crude, US Treasury yields, the rupee, foreign fund flows and earnings revisions. Together they show whether the pressure is easing, staying sticky or turning into currency stress.
