The National Taxpayers Union estimates that Trump's tariffs will cost the average U.S. household an additional $2,048 a year or about $171 per month. Consumers will face an overall effective tariff rate of 18%, the highest since 1934, according to the Yale Budget Lab.

The president also touted agreements over hundreds of billions of dollars in foreign investment into the United States.

US President Donald Trump's decision to impose 25% tariffs on goods imported from India could hit the country's growth prospects, experts say. It is unclear how big the hit could be, given that Trump has announced an unspecified penalty in addition to the 25% tariff rate.
