美国最高法院将于11月5日就特朗普关税案听取口头辩论 万亿美元退税风险或引发市场震荡

Core Points - The U.S. Supreme Court will hold oral arguments on November 5 regarding the legality of President Trump's global tariff plan, which is a significant test of his economic and trade policies [1] - The case centers on whether Trump exceeded presidential authority and misused the International Emergency Economic Powers Act (IEEPA) [1] - If the Supreme Court rules the tariffs illegal, the U.S. Treasury may have to refund approximately half of the collected tariff revenues, potentially leading to a financial burden on federal finances [1] Group 1: Impact on Companies - If the court overturns some tariffs, companies may apply for refunds, which could provide short-term financial benefits and improve earnings [2] - However, consumers may not see immediate price reductions as companies have already absorbed or shifted costs due to tariffs [2] - Companies will face operational challenges in confirming refund eligibility and managing potential "tariff vacuum periods" before new policies are established [2][3] Group 2: Market Reactions - Wall Street analysts predict that stocks of companies closely related to tariffs may rise in the short term due to market expectations, but long-term uncertainty remains high [2] - Even if tariffs are overturned, consumers are unlikely to benefit immediately during the holiday shopping season due to prior inventory purchases [2] Group 3: Alternative Measures - If the Supreme Court rules against Trump, the White House may quickly implement alternative measures, such as temporary tariffs under the Trade Act of 1974, but these would be limited in duration and complexity [3] - The Trump administration may seek legislative support from Congress for tariffs, but this approach carries higher risks due to the unpopularity of tariff policies [4] Group 4: Specific Case of Swiss Tariffs - The Trump administration recently imposed a 39% tariff on Swiss exports, leading to a significant drop in Swiss exports to the U.S., particularly in watches and gold [4] - The trade deficit with Switzerland has narrowed to its lowest level since 2020, indicating a direct impact of the tariff policy [4]
