4月4日周五，纳指100ETF（QQQ）股价出现大幅下跌，盘中跌幅一度达到5%，引发市场广泛关注。
造成纳指100ETF大跌的主要原因是中美贸易紧张局势突然升级。据报道，中国国务院关税税则委员会宣布，对原产于美国的所有进口商品加征34%关税。这一消息引发了全球金融市场的动荡，美国股市期货大幅下挫，纳斯达克100指数期货跌超2%。
除中美贸易因素外，全球主要股指也普遍下跌。日经225指数大跌4%，德国DAX指数暴跌5%，法国CAC40指数大跌4.5%。同时，避险情绪上升，美国10年期国债收益率跌至近6个月低点，反映出投资者对经济前景的担忧加剧。
分析人士指出，此轮关税升级可能会对全球经济复苏造成打击，加大衰退风险。市场预期美联储可能加快降息步伐，以应对潜在的经济下行压力。目前交易员预期6月美联储将降息50个基点，年内共降息四次。然而，这也为美联储带来两难困境，既要应对经济压力，又要警惕通胀风险。
