人工智能相关债务引发担忧,投资者转向避险资产,美元走软

美元/日元走势概览

2026年10月22日(周四),受华尔街人工智能(AI)相关股票遭大幅抛售的影响,投资者纷纷转向更安全的资产,导致美元兑日元汇率下跌。截至2026年10月23日北京时间04:53,日元兑美元汇率升至156.80,创下9月18日以来的最高水平。

走势背后的主要驱动因素

美国科技股的下跌,主要源于市场对企业为资助AI基础设施而大量举债的担忧。作为AI领域的大型基础设施建设方,Meta Platforms上调了资本支出预期,并宣布将发行一类新的无投票权股票,旨在为其AI发展计划筹集资金。

美元汇率往往易受资本支出相关担忧的影响,在此背景下,投资者转而寻求日元这一传统避险资产。日元汇率还突破了10月份以来的交易区间,引发了空头回补。

市场数据与反应

随着投资者寻求避险,美国国债价格上涨,10年期美债收益率下跌近20个基点,至4.95%左右,创下自2023年3月以来的最大单日跌幅。纳斯达克指数经历了自6月以来表现最糟糕的一天。周五亚洲交易时段,随着美元进一步走软,日元涨幅扩大,触及一个多月以来的最高水平。

市场担心日本当局可能在汇率接近158水平时进行干预,这使得交易员在重新建立大规模做多美元的头寸时保持谨慎。

更广泛的市场影响

美元的下跌并非全面性的。欧元小幅走低,其上行空间受到法国政治与财政动荡的制约。

由于美国经济日程清淡,且美联储正处于政策会议前的“静默期”,影响美元走势的因素仅限于油价、债券市场和华尔街表现。市场普遍预计,美联储将在下周的会议上维持利率不变。以马修·卢泽蒂为首的德意志银行分析师团队预计,美联储主席沃什将援引近期通胀数据,以支持其9月份的观点——即美联储未来可能需要进一步收紧货币政策。

货币市场已完全消化了日本央行将维持利率不变的预期,投资者正密切关注行长植田和男更新后的通胀预测。掉期市场则愈发倾向于认为,日本央行下一次加息将出现在明年初。

外汇交易员应关注的事项:

  • 2026年10月28日美联储的利率决议,以及沃什的新闻发布会。
  • 2026年10月29日欧洲央行的利率决议。
  • 2026年10月30日日本央行的利率决议,包括植田和男更新后的通胀预测。
  • 下周其他人工智能领域超大规模企业的季度财报。
