【环球财经】削弱规则、增加变数——多国专家批评美关税政策冲击全球贸易环境

Group 1 - The U.S. Supreme Court ruled that the International Emergency Economic Powers Act does not authorize the president to impose large-scale tariffs, leading to the Trump administration's announcement of a 15% tariff on goods from all countries and regions, which increases global trade uncertainty [1][4] - Experts indicate that the core issue of the current tariff dispute is not the tax rate itself but the declining predictability of global trade rules, which undermines market trust [2][5] - The temporary nature of the tariffs, as implemented under the Trade Act of 1974, has not alleviated market anxiety but rather exacerbated uncertainty, with the execution of tariffs being inconsistent [4][7] Group 2 - The frequent changes in tariff policy are forcing companies to allocate resources to adapt to policy shifts rather than focusing on production and technological development, which could lead to reduced employment [2][6] - Companies, including at least ten Japanese firms, have filed lawsuits for tax refunds, indicating a significant legal and financial burden stemming from the tariff changes [3][4] - The uncertainty surrounding U.S. trade policies is prompting countries like the UK and Australia to diversify their trade partnerships to mitigate risks associated with reliance on U.S. policies [7][6]
