On April 10, 2018, U.S. President Trump announced a 90-day suspension of new tariffs on over 75 countries that had not taken retaliatory measures, and unified existing tariffs to a rate of 10%. However, China was excluded from this, and tariffs on China were instead increased 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 exacerbated trade frictions between the U.S. and China and could drive up U.S. inflation, impacting global economic stability.
