India’s BSE Sensex fell about 0.4% to 76,957.3 on Monday, reversing its previous-session gains as rising crude prices linked to escalating US-Iran tensions and concerns over US interest rates kept investors cautious. A new closing-price mechanism for stocks with futures and options, along with MSCI index rebalancing, added to market pressure. The MSCI changes taking effect on September 1 will add Laurus Labs, Lenskart, Adani Energy Solutions and Groww, while removing Balkrishna Industries, SBI Cards and Astral; Reliance Industries’ weight will decline and Adani Enterprises’ will rise. Adani Ports, ITC, Bharti Airtel, Infosys and Kotak Mahindra Bank were among the biggest decliners. HDFC Bank fell about 1.5% after CEO Sashidhar Jagdishan said he would not seek a third term in October, revising an earlier account that reported a gain. Sun Pharma, ICICI Bank, Axis Bank and State Bank of India posted the biggest advances. The index recorded a monthly loss of around 1.5% in August.
