周三下午，美国股市暴跌至盘中低点，美联储主席鲍威尔的讲话突显了关税风险，芯片制造商的大幅抛售动摇了市场信心。标准普尔500指数下跌2.3%，道琼斯指数下跌600多点，纳斯达克指数下跌3.2%。英伟达股价暴跌8%以上，此前该公司公布了55亿美元的费用，原因是美国新的出口规定影响了其向中国出口的H20芯片。其他芯片制造商也纷纷效仿，AMD（-8.1%）和美光科技（-2.7%）均因成本警告和需求疲软而下跌。美联储主席杰罗姆·鲍威尔（Jerome Powell）也加剧了抛售，他警告称，关税可能导致通胀上升和经济增长放缓，使央行更难实现其政策目标。3月份零售额增长1.4%，为2023年1月以来的最大增幅，因为消费者在关税前争相购买汽车。然而，由于担心贸易限制的长期影响，市场情绪仍然消极。

U.S. stocks plunged to session lows Wednesday afternoon, spooked by Fed Chair Powell’s remarks highlighting tariff risks and a sharp sell-off in chipmakers that shook market confidence. The S&P 500 fell 2.3%, the Dow dropped over 600 points, and the Nasdaq sank 3.2%. Nvidia shares plunged more than 8% after revealing a $5.5 billion charge due to new US export rules affecting its H20 chip shipments to China. Other chipmakers followed suit, with AMD (-8.1%) and Micron Technology (-2.7%) both falling on cost warnings and weak demand. Fed Chair Jerome Powell added to the selloff, cautioning that tariffs could lead to higher inflation and slower growth, making it harder for the central bank to meet its policy goals. Retail sales rose 1.4% in March, the strongest gain since January 2023, as consumers rushed to buy cars ahead of tariffs. However, market sentiment remained negative amid concerns over the long-term impact of trade restrictions.
