【真灼港股名家】特朗普提高全球关税税率 若美股重挫将提升美元

Core Viewpoint - The announcement by President Trump to raise the temporary global tariff rate to 15% exacerbates trade tensions, despite a recent Supreme Court ruling that limited the government's authority to impose comprehensive tariffs [2]. Group 1: Legal and Trade Implications - The Supreme Court ruled 6-3 that the International Emergency Economic Powers Act (IEEPA) does not grant the president the power to implement comprehensive tariffs, reinforcing Congress's role in tax and trade policy [2]. - The higher tariffs will take effect immediately and can last up to 150 days, although they may face legal challenges regarding potential tariff refunds, which could exceed $175 billion [2]. - Trump's announcement highlights that trade tensions remain a core macro risk for investors, with close monitoring of future policy developments expected [2]. Group 2: Economic Impact - The uncertainty surrounding whether the government will refund the billions already collected in tariffs could affect trade agreements with neighboring countries like Canada and Mexico, although the US-Mexico-Canada Agreement (USMCA) is expected to mitigate severe impacts [3]. - The anticipated economic growth may be hindered by ongoing trade friction, complicating the Federal Reserve's decision-making regarding interest rate cuts, especially if the U.S. stock market experiences a decline of over 10% [3]. - The government faces a significant deficit of $1.8 trillion, and if lower courts mandate the refund of the $175 billion in illegally collected tariffs, the Treasury may need to issue more short-term notes and treasury bonds to cover the losses, potentially raising interest rates [3]. Group 3: Currency and Market Reactions - Due to expectations of pressure on U.S. stocks, the dollar is likely to rebound significantly, with the dollar index expected to test important resistance levels between 99.50 and 100.50 in the coming weeks [3].
