The BSE Sensex dropped 400 points, or 0.5%, to 80,618 in morning trade on Tuesday, erasing gains from the previous session, mainly weighed by tech, healthcare, and financial services. Market sentiment was dampened by renewed concerns over India’s GDP outlook after US President Trump reiterated his threat to impose substantial tariffs on Indian imports if the country continues purchasing oil from Russia. Investors also looked ahead to the RBI’s policy meeting on Wednesday, with expectations that the central bank will keep interest rates unchanged amid uncertainty over the economic impact of potential US trade actions. Attention also turned to Q1 corporate earnings, with major companies including Bharti Airtel, Britannia, and Adani Ports scheduled to report results today. On the data front, final figures showed that India’s private sector grew at the fastest pace in 15 months in July. Among the biggest laggards were Infosys (-1.6%), Adani Ports (-1.5%), and Power Grid (-0.9%).
