周三，美元指数在上一交易日回落后徘徊在98.3附近，受到对美联储独立性的重新担忧和对美元全球主导地位信心减弱的压力。本周早些时候，唐纳德·特朗普总统表示，他将因抵押贷款欺诈指控罢免美联储理事丽莎·库克，尽管库克的律师表示，她将采取法律行动阻止解雇。分析人士警告称，库克的潜在下台可能会增加早些时候降息的可能性，特朗普将对央行施加更大的影响力。市场目前预计，美联储9月份降息25个基点的可能性为87%。展望未来，投资者等待周五公布的个人消费支出价格指数，这是美联储首选的通胀指标，以获取有关政策前景的更多线索。

The dollar index hovered near 98.3 on Wednesday after retreating in the previous session, pressured by renewed concerns about the Federal Reserve’s independence and weakening confidence in the greenback’s global dominance. Earlier this week, President Donald Trump said he would remove Fed Governor Lisa Cook over allegations of mortgage fraud, though Cook’s lawyer stated she will pursue legal action to block the dismissal. Analysts warned that Cook’s potential ouster could heighten the likelihood of earlier interest rate cuts, with Trump asserting greater influence over the central bank. Markets are now pricing in an 87% probability that the Fed will reduce rates by 25 basis points in September. Looking ahead, investors await Friday’s release of the PCE price index, the Fed’s preferred inflation measure, for additional clues on the policy outlook.

周三，美国股指期货小幅上涨，投资者将注意力转向Nvidia的收益，这被视为市场的下一个主要催化剂。在长期交易中，MongoDB飙升近30%，Okta上涨约6%，此前两者均超过了华尔街的预期，这得益于开发人工智能平台的公司的强劲需求。Cracker Barrel也上涨了7%以上，此前该公司宣布将在客户和唐纳德·特朗普总统的强烈反对下取消其新标志。在周二的常规交易日，道琼斯指数上涨0.3%，标准普尔500指数上涨0.41%，纳斯达克综合指数上涨0.44%。标普11个板块中有7个板块收盘上涨，工业、金融和医疗保健板块领涨。尽管在特朗普总统史无前例地罢免美联储理事丽莎·库克后，人们对美联储独立性的担忧加剧，但这一收益还是出现了。

US stock futures edged higher on Wednesday as investors turned their focus to Nvidia’s earnings, seen as the next major catalyst for markets. In extended trading, MongoDB surged nearly 30% and Okta gained about 6% after both beat Wall Street expectations, driven by strong demand from firms developing artificial intelligence platforms. Cracker Barrel also jumped more than 7% after announcing it will scrap its new logo following backlash from customers and President Donald Trump. In Tuesday’s regular session, the Dow rose 0.3%, the S&P 500 added 0.41% and the Nasdaq Composite climbed 0.44%. Seven of the 11 S&P sectors finished higher, led by industrials, financials and health care. The gains came even as concerns about the Fed’s independence intensified after President Trump’s unprecedented removal of Federal Reserve Governor Lisa Cook.

美国总统唐纳德·特朗普表示，在因被指控伪造抵押贷款文件而罢免美联储理事丽莎·库克后，他已准备好进行法律斗争。与此同时，央行表示，将尊重库克对解雇她的法律质疑中的任何法院裁决。特朗普试图罢免她，这在美联储作为名义上独立的美国机构111年的历史上是前所未有的，这引发了人们对货币政策政治压力的担忧。路透社表示，如果库克的席位空缺，特朗普将有机会任命美联储七人董事会的多数成员，这对美国总统来说是一个难得的机会。他已经提名白宫经济学家斯蒂芬·米兰（Stephen Miran）担任一个将于1月到期的临时席位，并建议考虑让米兰接替库克的职位。《华尔街日报》还报道称，前世界银行行长、特朗普的亲密盟友戴维·马尔帕斯已被提名为另一位候选人。

U.S. President Donald Trump said he was ready for a legal battle after moving to oust Federal Reserve Governor Lisa Cook over allegations she falsified mortgage documents. Meanwhile, the central bank stated it would respect any court ruling in Cook’s legal challenge against her dismissal. Trump’s attempt to remove her is unprecedented in the Fed’s 111-year history as a nominally independent U.S. institution, raising alarms over political pressure on monetary policy. Reuters said that if Cook’s seat is vacated, Trump would gain the chance to appoint a majority of the Fed’s seven-member board, a rare opportunity for a U.S. president. He has already nominated White House economist Stephen Miran to a temporary seat that expires in January, and suggested Miran could be considered for Cook’s role. The Wall Street Journal also reported that David Malpass, former World Bank President and a close Trump ally, has been floated as another candidate.
