April 9: Trump's higher "reciprocal tariffs" begin just after midnight. Hours later, the president says he is issuing a 90-day pause on those duties, except for China. Trump raises tariffs on Chinese goods from 104% to 145%, the highest rate so far this year.

Trump has sent letters to leaders of dozens of countries outlining the tariff levels set to begin on Aug. 1. In recent months, Trump has rolled back some of his steepest tariffs, meaning delays could be possible in the case of the Aug. 1 deadline. The Trump administration appears to have stood largely behind the deadline in recent days, however.

The United States appears firm on its slated tariff increase on the EU following comments made by U.S. Commerce Secretary Howard Lutnick over the weekend.

European exporters say a 30% U.S. import tariff would drive prices unsustainably high and hammer their sales. While some manufacturers are shifting their supply chains stateside or elsewhere, not all businesses have the same flexibility — and can't easily replace the developed U.

Re “A look at the 14 countries that received Trump’s tariff letters” (July 8): President Trump’s helter-skelter application of tariffs is bad for the U.S. and bad for world

Analysts at Citi and at Deutsche Bank have looked into who is paying for the tariffs imposed by the Trump administration this year.

America is carrying massive debt, and half of it is financed by the rest of the world. If foreign nations and investors coordinated, they could force Trump to negotiate more reasonably on tariffs. Will they take the risk?
