Highlights

- •NSE Nifty ended 109 points lower at 23,946.25, with major declines in the auto and financial sectors.

Indian equity markets experienced a downturn on Monday, June 29, 2026, as investors reacted to renewed geopolitical hostilities between the United States and Iran. This global uncertainty, paired with rising crude oil prices and a strengthening dollar, led to a decline in the BSE Sensex and the NSE Nifty, effectively ending a two-day winning streak for both indices.
The BSE Sensex fell by 372.10 points, or 0.48%, closing at 76,728.37. Throughout the session, the index showed significant volatility, dipping as much as 478.72 points at one stage. Similarly, the 50-share NSE Nifty dropped 109.75 points, or 0.46%, to settle at 23,946.25. The sell-off was broad-based, with 12 out of 15 major sectoral indices ending in the red, led by a 2% decline in the Nifty Auto index.
Market Sell-off and Key Corporate Developments
The downward pressure on the markets was largely attributed to losses among major index heavyweights. Kotak Mahindra Bank saw its shares slide by nearly 3% following the announcement that its managing director and CEO, Ashok Vaswani, will step down at the end of his current three-year tenure on December 31, 2026, and will not seek re-appointment. Other notable decliners included Reliance Industries, Mahindra & Mahindra, Larsen & Toubro, Maruti Suzuki, and the State Bank of India.
Despite the overall negative market breadth, certain sectors attracted buying interest. Companies such as Max Healthcare, Dr. Reddy’s Labs, Coal India, Bharat Electronics, and Trent managed to post gains. Additionally, Hexaware Technologies saw a significant jump of 9% after securing a strategic partnership as an authorized reseller for Amazon Bedrock.
Analysts suggest that while the initial escalation between the United States and Iran regarding the Strait of Hormuz was tempered by an agreement to resume talks, the underlying instability remains a concern. With Brent crude prices climbing to $73.09 per barrel, the market remains susceptible to further headline-driven volatility.
Broader market indices also faced selling pressure, as the Nifty Midcap 100 and Nifty Smallcap 100 indices declined by 0.37% and 0.62%, respectively. Market participants are now closely monitoring both global geopolitical developments and domestic financial updates as they navigate the current environment of uncertainty.
