The Nifty 50 index closed at 23,140.50 on September 25, 2026, marking its seventh straight weekly decline. This represents its longest losing streak since the seven-week fall observed during the COVID-19 pandemic-driven global selloff in February-April 2020. The index fell by 205.90 points, or 0.9%, from its previous week's close and has lost 5.8% over the past seven weeks. Despite a 0.3% rise on Friday, the Nifty remains 12.3% below its 52-week high of 26,373.20 and 4.3% above its 52-week low. Experts note the Nifty has entered an oversold zone, potentially signaling a short-term rebound, though a sustained recovery would require broader market participation.

Several factors contributed to this downturn. Rising US Treasury yields and elevated crude oil prices significantly weighed on investor sentiment. Geopolitical uncertainties, particularly around US-Iran tensions and broader Middle East developments, also played a role. Domestic developments, such as the reappointment of N Chandrasekaran as chairman of Tata Sons, which was opposed by Tata Trusts, led to a combined loss of over $4.87 billion (₹40,681 crore) in market value for 18 of the Tata group's 23 listed companies. FIIs were net sellers of $1.38 billion (₹11,490 crore) during the week, while DIIs bought $1.97 billion (₹16,398 crore), indicating a divided cash-market flow.

Key sectors experienced significant losses. The information technology sector lost $5.81 billion (₹48,435 crore), or 2.1% in market value, during the week. Insurance companies saw a combined loss of $842 million (₹7,000 crore), or 0.6%. PB Fintech, a dominant online insurance aggregator, was hit particularly hard, losing $3.36 billion (₹28,000 crore), or 33%, of its market value. The BSE Insurance index fell 2% to 1,486.5 points. Financial Services also saw a 1.6% decline, and Nifty Bank fell 1.3%. Analysts anticipate more pain ahead, with the Nifty 50 potentially breaking below crucial support levels at 23,000 and 22,800, though some experts foresee a bottoming out in October 2026.
