周三晚间，美国股指期货小幅下跌，周四6月15日市场休市。在常规交易时段，道琼斯指数和标准普尔500指数分别下跌0.1%和0.03%，而纳斯达克综合指数上涨0.13%。此举是在美联储保持利率稳定之后做出的，主席杰罗姆·鲍威尔在地缘政治和经济不确定性上升的情况下采取了谨慎的语气。鲍威尔重申了一种依赖数据的方法，指出特朗普总统的关税对通胀的影响尚不清楚，还有滞胀的风险。美联储目前的预测包括2025年的两次降息，以及下调的增长预期和更高的通胀预测。中东紧张局势升级进一步抑制了投资者情绪，持续的以色列-以色列冲突引发了对美国进一步介入的担忧。标普500指数的11个板块中有7个收盘下跌，能源板块领跌，科技板块表现优于大盘。

US stock futures edged lower Wednesday evening ahead of Thursday’s market closure for Juneteenth. During the regular session, the Dow Jones and S&P 500 slipped 0.1% and 0.03%, respectively, while the Nasdaq Composite gained 0.13%. The moves came after the Federal Reserve held interest rates steady, with Chair Jerome Powell striking a cautious tone amid rising geopolitical and economic uncertainty. Powell reaffirmed a data-dependent approach, pointing to unclear inflation impacts from President Trump’s tariffs and the risk of stagflation. Fed projections now include two rate cuts in 2025, alongside downgraded growth expectations and higher inflation forecasts. Investor sentiment was further dampened by escalating tensions in the Middle East, as the ongoing Israel-Iran conflict stoked fears of deeper US involvement. Seven of the 11 S&P 500 sectors ended the day in the red, led by declines in energy, while technology outperformed.
