创可贴、火箭筒与回旋镖：在波动的美国利率环境中进行股票投资

关键论点

• 长期收益率上升受结构性因素推动，包括财政赤字、巨额借贷、全球资本流动转变和杠杆化国债头寸。
• 美国财政部有限的干预措施不太可能改变收益率上升的整体格局。
• 股票投资者应保持估值纪律，并预期市场领导地位变化更加频繁。
• 政策工具从“创可贴”（如回购）到“火箭筒”（如量化宽松）不等，效果各异，且存在“回旋镖”效应的风险。
• 日本可能的资本回流可能减少对美国资产的外国需求，加剧收益率上行压力。
• 国债基差交易使对冲基金国债敞口翻倍，使市场容易发生自我强化的抛售。
• 通胀回落可能带来缓解，减轻收益率压力并改善股票估值。

3. I continue to believe that the core of the Federal Open Market Committee remains focused on the economic data, particularly inflation and employment, rather than on concerns about Treasury financing or fiscal sustainability. · short-term
