India’s BSE Sensex finished about 1.7% down at 76,015.3 on Monday, the lowest in over a month, marking the third straight session of losses. Stranded US-Iran negotiations, rising crude oil prices, sustained foreign exchange outflows and Prime Minister Narendra Modi's austerity push triggered broad-based selling. Consumer-linked stocks saw heavy selling after PM Modi’s call to curb fuel consumption, reduce unnecessary foreign travel and avoid non-essential imports such as gold. Jewellery major Titan Company plunged nearly 7%, while Trent and Asian Paints fell 1.5% and 1.3%. IndiGo slipped 4.7% on higher jet fuel costs. Financial stocks also weakened, with State Bank of India down 4.5%, extending losses after a profit miss, and HDFC Bank, Bajaj Finance, and Bajaj Finserv declining 2.1%, 2%, and 1.2%. TCS edged down 0.1% despite strong FY27 guidance and better-than-expected earnings. Among top gainers, Sun Pharma and Hinustan Unilever stood out, rising 1.4% and 0.9%, respectively.
