US President Donald Trump announced a 26% “discounted reciprocal tariff” on Indian imports, citing India's high duties on US goods. He noted that India imposes a 56% tariff on American products, prompting the US to counter with a 26% levy.

For decades, global commerce abided by tariff rates agreed to by the U.S. and 122 other countries during the 1980s and 1990s. On Wednesday, Trump detonated that arrangement, saying that other countries had exploited the system and “ripped off’’ the United States for years, causing its once-mighty manufacturing base to shrink.
