MUMBAI — Indian equity benchmarks suffered a steep, across-the-board sell-off on Thursday, September 24, 2026, as surging US Treasury yields, elevated crude oil prices, regulatory headwinds, and persistent foreign institutional outflows rattled investor sentiment.

The 30-share BSE Sensex tumbled over 1,200 points (approx. 1.6%–1.7%) to settle in the 73,580–73,608 range, while the broader NSE Nifty 50 shed around 385 points (1.65%) to close near 23,060. Mid- and small-cap segments suffered steeper cuts, with the Nifty Midcap 100 sliding over 2% and the Nifty Smallcap 100 declining 1.8%, while the India VIX spiked sharply to reflect mounting volatility.

Key Drivers Behind the Market Fall on 24 Sep, 2026

  • Surging US Treasury Yields & Fed Rate Fears: The benchmark 10-year US Treasury yield surged past 5.10%—reaching multi-decade highs not seen since 2007. Robust US business activity data stoked fears that the Federal Reserve may keep rates elevated longer or execute further hikes, accelerating capital shifts out of emerging markets into dollar assets.
  • Brent Crude Above $102: Geopolitical tensions involving the US and Iran pushed Brent crude prices past $102 per barrel. As a net energy importer, higher crude prices stoke India’s domestic inflation and widen the current account deficit.
  • Regulatory Shocks to Financials: The Insurance Regulatory and Development Authority of India (IRDAI) released a consultation paper proposing new caps on distributor commissions and expense limits. This triggered heavy liquidation across NBFCs, insurers, and private banks. Heavyweights like Bajaj Finance dropped more than 5%, while Axis Bank, HDFC Bank, and Kotak Mahindra Bank faced consistent selling pressure.
  • Rupee Depreciation & FPI Outflows: The Indian rupee weakened to around ₹95.87 against the US dollar. Foreign Portfolio Investors (FPIs) extended their net-selling streak, having pulled nearly ₹20,974 crore from domestic equities in September alone.

Historic NSE Listing Held Back by Bearish Tone

Against the backdrop of broader market turmoil, the National Stock Exchange of India (NSE) marked a historic milestone by debuting its shares exclusively on rival platform BSE Limited following its ₹22,561.57-crore Initial Public Offering (IPO).

The stock listed at ₹1,800 per share—a modest 0.84% premium over its issue price of ₹1,785. While institutional buying lifted the shares to an intraday high of ₹1,878, risk-off sentiment in the secondary market capped its gains, with the stock eventually settling around ₹1,839 (up ~3% from the issue price).

Analysts noted that equity markets are likely to remain range-bound and volatile until US bond yields cool and crude oil prices stabilize.
