美最高法否决全面关税后，特朗普火速加征新税！经济学家警告：美国经济或成最大输家

Core Viewpoint - The U.S. Supreme Court's ruling against Trump's comprehensive tariff policy has intensified trade tensions, with economists warning that the U.S. economy may suffer the most as a result of these developments [1]. Group 1: Supreme Court Ruling and Immediate Impact - The Supreme Court ruled 6-3 that Trump's large-scale tariffs imposed under the International Emergency Economic Powers Act lacked legal authorization [1]. - Following the ruling, Trump swiftly imposed new tariffs of up to 15% on multiple trade partners, effective immediately, escalating the already tense global trade situation [1]. Group 2: Economic Repercussions - Economists, including Moody's chief economist Mark Zandi, predict that the trade war will create a cautious atmosphere among businesses and foreign governments, leading to reduced investment and hiring in the U.S. [2]. - There is a growing perception that the U.S. is poorly managing its economy, which may drive foreign governments to seek trade alternatives, potentially shifting trade away from the U.S. to other partners, including China [2]. Group 3: Future Trade Policies - The U.S. Trade Representative indicated that the Trump administration will continue its trade policies, utilizing various provisions of the Trade Act of 1974 to justify the new tariffs [3]. - The effectiveness of the new tariffs may be limited, as some economists suggest that the overall impact on effective tariff rates and inflation predictions will be minimal in the short term [3].
