Sensex, Nifty, Share Price LIVE: Domestic markets opened sharply lower today. Sensex plunged 412.87 points or 0.56 % to trade at 72,673.07 as at 9.17 am, and Nifty 50 dipped 146.20 points or 0.66% to 21,973.10. Trump’s proposed 25% tariffs on Canada, Mexico and a cumulative 20% tariff on China will go into effect from 10:31 a.m. IST on Tuesday. Trump also said reciprocal tariffs will start on April 2, escalating trade tensions and dragging financial markets. Higher tariffs, besides their potential adverse impact on global growth, could spur inflation in the U.S., leading to higher interest rates for longer and hurting flows into emerging markets such as India. Analysts expect the Nifty to find support around 21,800-22,000, with key resistance at 22,300-22,450. With ongoing geopolitical risks and trade tensions, market participants remain cautious while selectively accumulating quality stocks for the medium term.
