Dalal Street opened October on a negative note as benchmark indices suffered their fourth straight session of declines, locking in an eighth consecutive weekly loss—the longest weekly slump in 25 years. The BSE Sensex plunged to a fresh 52-week low of 71,292.88 before recovering to settle at 71,909.70, while the Nifty 50 closed down 198.50 points at 22,421.95. Unrelenting foreign institutional selling crossing $27.8 billion year-to-date and 24-year-high US Treasury yields at 5.34% continued to pressure equities, with the Nifty Auto index sliding over 4% despite steady delivery data.

Dalal Street closed out a bruising September on Wednesday as an intraday recovery of over 500 points in the Sensex completely unraveled before the close. The Nifty 50 ended down 95.75 points at 22,620.45, capping a monthly decline of 5.67%, while the Sensex finished nearly flat at 72,480.29. Stalled diplomatic progress over the Strait of Hormuz, relentless FII outflows of ₹24,054 crore across four sessions, and 19-year-high US Treasury yields continued to suppress risk appetite despite strong performances from large-cap IT counters.

Dalal Street witnessed a sharp second-half recovery on Tuesday as the Nifty 50 rebounded from an intraday low of 22,569.65 to close down just 64 points at 22,716.20, while the BSE Sensex recovered nearly 500 points to settle at 72,529.07. Aggressive buying by domestic institutions cushioned aggressive FII selling of over ₹5,350 crore, but elevated Brent crude at $107 and a weakening rupee past 96 continue to keep market sentiment cautious.

From October 15, 2026, UPI transactions above ₹2,000 made to merchants will carry a 0.4 percent Merchant Discount Rate (capped at ₹300) to support payment infrastructure and cybersecurity costs. While all person-to-person transfers and 96% of merchant payments remain free with no added cost to consumers, retail bodies like AIMRA have called for a ‘No UPI Day’ protest on October 2, citing steep margin pressures on high-value electronic sales.

Dalal Street suffered another severe beating on Monday, September 28, as benchmark indices sank to their lowest levels since April. The BSE Sensex plunged 1,124.02 points to hit a fresh 52-week low of 72,716.23, while the Nifty 50 broke below key support to settle at 22,780.25. A confluence of surging Brent crude above $106, US 10-year Treasury yields crossing 5.2%, and geopolitical deadlock over the Strait of Hormuz sparked aggressive foreign institutional selling, wiping out ₹5 lakh crore within the first 70 minutes of trade.

Dalal Street mounted a resilient late-afternoon comeback on Thursday, September 25, as the BSE Sensex reclaimed 315.20 points to close at 73,895.74 and the Nifty 50 defended the 23,000 threshold to settle at 23,140.50. Bargain hunting in beaten-down financials and RBI intervention in the currency market helped stem losses, though persisting geopolitical frictions in the Strait of Hormuz and elevated US Treasury yields keep traders cautious.
