On April 10, 2018, U.S. President Trump announced a 90-day suspension of new tariffs on over 75 countries that had not retaliated, while unifying existing rates to 10%. However, China was excluded, and tariffs on China were instead raised to 125%. This policy aimed to provide U.S. companies with time to adjust their supply chains while pressuring China to make concessions in trade negotiations. The market reacted sharply, with U.S. stocks rebounding significantly, and the Nasdaq index rising by 12% in a single day. However, this policy intensified trade frictions between the U.S. and China and could increase U.S. inflation, impacting global economic stability.
