别为美最高法推翻特朗普关税高兴太早？华尔街预计市场反应或昙花一现

Core Viewpoint - The U.S. Supreme Court ruled that the global tariffs implemented by the Trump administration under the International Emergency Economic Powers Act (IEEPA) were unlawful, leading to asset price volatility and a focus on alternative legal measures for tariff implementation by the White House [1][2]. Group 1: Market Reactions - Following the Supreme Court's decision, the dollar index fell, U.S. Treasury prices dropped, and major U.S. stock indices saw limited gains, indicating a relatively mild market reaction [1]. - The market's positive response to the ruling is expected to be short-lived, as many market participants had anticipated this outcome [3]. - The ruling is seen as a temporary relief, reducing uncertainty but not ending the tariff narrative, as alternative legal avenues for tariffs remain [3][6]. Group 2: Fiscal Concerns - The ruling is expected to negatively impact the U.S. bond market, as the elimination of tariff revenue could exacerbate the federal budget deficit, potentially increasing it by $1.8 trillion [2][4]. - The absence of tariff revenue may lead to a higher issuance of bonds to cover the fiscal gap, contributing to upward pressure on long-term Treasury yields [4][5]. Group 3: Political Uncertainty - The focus has shifted to the political implications of the ruling, with Trump having multiple legal tools available for tariff implementation, though these may take longer to enact [6]. - The uncertainty surrounding potential alternative tariffs could impact U.S. economic growth prospects in the short term [6].
