At the interbank foreign exchange market, the domestic currency opened at 90.30, registering a strong gain from its previous close of 91.49. Forex traders said the tariff cut has altered market sentiment, improving India’s relative trade position and reopening the door for foreign institutional investor (FII) participation.
Late on Monday night, Prime Minister Narendra Modi and US President Donald Trump officially confirmed the much-anticipated India-US trade deal, which immediately lowered US tariffs on Indian goods 18%. Both leaders described the agreement as a turning point in economic ties between the world’s two largest democracies.
President Trump first announced the deal on his social media platform Truth Social. The development was later confirmed by Prime Minister Modi following a high-level call with the US President. “Wonderful to speak with my dear friend President Trump today. Delighted that Made in India products will now have a reduced tariff of 18%. Big thanks to President Trump on behalf of the 1.4 billion people of India for this wonderful announcement,” Modi said.
Commenting on the impact of the tariff reduction, Rajeev Juneja, President of PHDCCI, said the move signals a renewed US commitment to trade openness and economic efficiency. “Reduced tariffs lower input costs, strengthen supply chains and help ease inflation by cutting prices for businesses and consumers. Key sectors such as manufacturing, technology, healthcare and renewable energy stand to benefit through better access to intermediate goods and capital equipment,” he said, adding that the decision reflects growing trust and predictability in bilateral trade.
