Indian equity markets faced significant selling pressure on Thursday, September 24, 2026, as both the BSE Sensex and NSE Nifty50 closed sharply lower. The 30-share Sensex plummeted 1,193.62 points, or 1.60%, to settle at 73,634.63, while the Nifty50 declined 384.55 points, or 1.64%, to 23,062.25. This broad-based weakness saw all major sectoral indices trading in the red, and the India VIX, a key indicator of market fear and expected volatility, spiked by 24.33% to 12.86.
Factors Driving the Indian Market Crash
The sharp downturn in Indian markets was attributed to a confluence of domestic and global factors, creating a climate of risk aversion among investors.
Irdai's Proposed Insurance Reforms
A significant domestic concern emerged from the Insurance Regulatory and Development Authority of India's (Irdai) proposed distribution reforms. JM Financial highlighted potential implications for select banking and non-banking financial companies (NBFCs). The regulator's consultation paper suggests lower Expenses of Management (EOM) caps for insurers and reintroduces segment-level commission caps, which could impact the bancassurance channel. Banks with higher insurance fee income, such as Ujjivan Small Finance Bank, AU Small Finance Bank, IDFC First Bank, Bandhan Bank, DCB Bank, and Axis Bank, are particularly in focus. Similarly, NBFCs like L&T Finance, Bajaj Finance, and Mahindra & Mahindra Financial Services could face impacts.
Rising Crude Oil Prices
Globally, the sharp rise in Brent crude oil prices, climbing towards $106 a barrel, contributed to market jitters. Elevated energy costs typically fuel inflationary concerns and can weigh on corporate earnings and economic growth.
Soaring US Treasury Yields
The increase in US Treasury yields also played a crucial role. The US 10-year Treasury yield rose to approximately 5.13%, marking its highest level since 2007, while the two-year yield stood around 4.89%. Rising yields in the US often draw capital away from emerging markets, including India, making them less attractive to foreign investors.
Weak Global Market Cues and Geopolitical Tensions
Global sentiment weakened following a sharp fall in US equities, which snapped record runs as the 10-year Treasury yield breached 5%. The US Dollar Index also strengthened, putting additional pressure on emerging market currencies and equities. Furthermore, renewed geopolitical concerns, particularly surrounding the US-Iran conflict, contributed to increased risk aversion across international markets, exacerbating the Indian market's decline.
