事关1万亿美元 美最高法院11月审议关税合法性

Core Viewpoint - The U.S. Supreme Court will expedite the review of the legality of tariffs imposed by the Trump administration, with oral arguments scheduled for the first week of November, potentially impacting U.S. economic policy and global trade dynamics [1][2]. Group 1: Legal Proceedings - The Supreme Court's decision to consolidate lawsuits from small business owners, 12 states, and a toy manufacturer against the Trump administration's tariffs may lead to a final ruling by the end of the year [1]. - The lawsuits challenge the authority of the Trump administration to impose tariffs under the International Emergency Economic Powers Act, arguing that there is no national emergency justifying such actions [2]. Group 2: Economic Implications - If the Supreme Court rules against the Trump administration, it could result in the need to refund tariffs amounting to an estimated $1 trillion by June next year, which would have catastrophic consequences for the administration [4]. - The effective tariff rate on imported goods in the U.S. has reached nearly 19%, the highest since the Great Depression, significantly above the typical 2-3% rates seen in modern times, potentially increasing annual household expenses by $2,400 due to elevated prices [5].
