India's BSE Sensex deepened losses to close nearly 1% down at 79,857.8 on Friday, a level last seen in May 9th, amid tariff-related concerns, unimpressive earnings and heavy foreign capital outflows. Trump’s tariff move - raising duties to a steep 50% from August 27 while firmly ruling out trade talks - has rattled investors and raised fresh concerns over the future of US-India relations. Additionally, global financial institutions, including Goldman Sachs, have begun revising India’s economic outlook downward, citing the adverse effects of the higher tariff. About 25 out of 30 stocks ended in negative terrain, led by Bharti Airtel, Tata Motors, M&M, Kotak Mahindra Bank, and Reliance Industries. On the other hand, NTPC, Titan, Trent, ITC, and Bajaj FinServ were only five gains. For the week, the Sensex posted a 0.9% decline, notching its sixth straight weekly loss, driven largely by uncertainty over new US tariffs.
