India's headline equity indices, the BSE Sensex and NSE Nifty, experienced extended selling pressure during early market sessions, following a steep single-day selloff that wiped out significant market valuation. The benchmark BSE Sensex traded lower around the 72,600 mark, while the broader NSE Nifty 50 slipped below the crucial 22,750 support level, extending losses driven by rising international crude oil prices, sustained foreign portfolio investment (FPI) withdrawals, and elevated global bond yields. Depository data indicates foreign institutional investors offloaded over ₹17,000 crore from domestic equities in September alone, driven by heightened geopolitical uncertainties in energy corridors and shifting global monetary policy expectations. Broader market indices—including the Nifty Midcap 100 and Smallcap 100—also registered pullbacks, with heavy weightage sectors like banking, power, and telecommunications taking the brunt of the market correction. Financial analysts observe that while domestic institutional investors (DIIs) continue providing crucial capital inflows to absorb selling pressure, near-term equity performance will remain closely tethered to crude oil benchmarks, foreign capital stability, and upcoming corporate quarterly earnings disclosures.

Global Risk-Off Wave Triggers Multi-Session Downslide on Dalal Street

Indian benchmark equity indices faced intense selling pressure for a second consecutive session on Tuesday, September 29, 2026, as a toxic combination of elevated crude oil prices, spiking US bond yields, and heightened geopolitical instability in West Asia spooked global investors. Following a brutal session on Monday where the BSE Sensex plunged 1,124.02 points (-1.52%) to hit a six-month low, the index dropped another 633 points (-0.87%) to open near 72,138.99. Simultaneously, the NSE Nifty 50 slipped 194 points (-0.85%) to trade near 22,586.60.

The market panic erased approximately ₹4 lakh crore in investor wealth within minutes of the opening bell on Tuesday, taking the total BSE listed market capitalization down to ₹474 lakh crore.

Triad of Drag: Spiking Crude, Treasury Yields, and Foreign Capital Outflows

Market strategists attribute the ongoing market rout to three interrelated global macro pressures:

  1. Surging Brent Crude Benchmarks: International oil prices extended their rally, with Brent crude crossing $107.10 per barrel. As India imports over 85% of its crude requirements, sustained prices above $100 heighten current account deficit worries, import-led inflation, and input cost pressures for domestic corporate margins.

  2. Relentless FII Offloading: Foreign Institutional Investors (FIIs) expanded their aggressive net selling, pulling out ₹5,353.22 crore in the previous session alone. FIIs have now registered six consecutive weeks of net selling in Indian equities, driven by capital reallocation toward higher-yielding US Treasury assets.

  3. Elevated US Treasury Yields: US 10-year Treasury yields climbed above 5.10%, diminishing the relative risk-reward attractiveness of emerging market equities.

Sectoral Breakdown and Short-Term Outlook

Heavyweight financial and rate-sensitive stocks bore the brunt of the assault on Tuesday. Bajaj Finance dropped over 2%, leading losses alongside index heavyweights HDFC Bank, Reliance Industries, Power Grid, and Kotak Mahindra Bank. The weakness extended to the broader market, with both the Nifty Midcap 100 and Nifty Smallcap 100 indices declining nearly 0.8%.

While Domestic Institutional Investors (DIIs) continue to channel retail SIP flows to cushion the market, analysts warn that equity recovery will remain capped until global energy markets stabilize and clarity emerges regarding diplomatic discussions in West Asia.
