Want evidence Trump’s tariffs are upending the global economy? Here it is

Ever since President Donald Trump introduced his first set of higher tariffs, it’s been a waiting game to see just how big an impact they’ll have on the global economy.

Ever since President Donald Trump introduced his first round of new tariffs, it’s been a waiting game to see just how much they’ll impact the global economy. This week, one of the earliest signs was revealed — and it wasn’t pretty. South Korea’s Customs Service reported that exports for the first 20 days of April declined by 5.2% compared to the same period last year. That singular data point is a “key bellwether” for where trade is heading, Min Joo Kang, a senior economist at ING, said in a note on Monday. The decline in exports came after Trump enacted a 25% tariff on all aluminum, steel and auto imports. All other South Korean imports were also briefly subject to a 25% “reciprocal” tariff before Trump delayed it until July. Instead, imports from there are subject to a nearly universal 10% tariff. That was evident in the data, which showed that car and steel shipments fell 6.5% and 8.7%, respectively, year over year for the first 20 days of April. Overall exports from South Korea to the US declined by 14.3% from last year. The bright spot was semiconductor exports, which rose 10.2% compared to last April. Semiconductors remain exempt from US tariffs, but Trump has said he aims to implement tariffs as high as 25% on the product.
