日本银行（BOJ）将政策利率调升 0.25 个百分点（四分之一码）至 1.25%，然而日圆兑美元汇率却重挫高达 1.3%。这项决定引发了内部阻力，央行政策委员会两名委员 Toichiro Asada 与 Ayano Sato 投下反对票。此外，总裁 Kazuo Ueda 发出的混杂信号及微弱的多数支持，部分抵消了日本与美国官方先前支撑日圆汇率的各项努力。

此强烈市场反应彰显出全球主要央行面临的严峻挑战以及交易员不断升高的预期。欧洲央行（ECB）上周完成了第二次升息，市场预期其存款利率将自现行的 2.5% 水平再上调至少三次。同时，美国联准会（Fed）于周三实施自 2023 年以来的首次升息，且市场交易员预计今年至少还会升息一次，至 2027 年最多将再升息两次。

伊朗冲突引发的能源价格飙升正加剧通货膨胀，进一步限制了央行抑制物价上涨的能力。与此同时，持续走高的公债殖利率引发了对各国政府偿还庞大债务能力的担忧。尽管各国央行总裁可能不愿承认，但在全球金融紧缩浪潮下，他们正面临日益被金融市场动向所主导的困境。

The Bank of Japan (BOJ) raised its policy rate by a quarter point to 1.25%, but the yen slumped by as much as 1.3% against the US dollar. The rate hike encountered internal resistance, evidenced by board members Toichiro Asada and Ayano Sato voting against the move. Alongside mixed signals from Governor Kazuo Ueda, the outcome partially reversed joint Japanese and US efforts to stabilize the currency.

This substantial reaction illustrates the intricate challenges confronting global central bankers amid aggressive trader expectations. The European Central Bank implemented its second rate increase last week, with markets pricing in at least three further increases above its current 2.5% deposit rate. Concurrently, the Federal Reserve hiked borrowing costs on Wednesday for the first time since 2023, with traders pricing at least one additional hike this year and up to two in 2027.

Central banks face constrained options to rein in inflation driven by high energy prices from the Iran conflict. Simultaneously, rising government bond yields threaten sovereign debt sustainability worldwide. Consequently, monetary policymakers are growing increasingly vulnerable to market pressures and external economic headwinds.
