<h1>India-US trade deal driving tariff certainty boosts markets, lifting major indices and prompting broad sectoral buying.</h1> An interim India-US trade agreement signaling tariff reductions and deeper economic cooperation spurred broad investor buying, lifting Sensex to about 84,066 and Nifty to about 25,867. Gains were led by PSU banks, consumer durables, realty and commodities, supported by foreign institutional investor inflows and expectations of demand revival, showing how reduced tariff uncertainty drove sectoral accumulation and improved risk appetite across midcap and smallcap segments.
