美国国债市场近期经历剧烈震荡，十年期美债收益率自4.7%以下飙升至5%并短暂突破该关口，三十年期收益率更升穿5.35%，推动30年期平均房贷利率突破7%，在中期选举前加剧了选民的生活成本危机。在美债总存量于过去十年间翻倍达40万亿美元的背景下，联邦债务利息支出已耗费约五分之一的税收收入，逼迫财政部以二十年未见的高成本再融资。为此，财长斯科特·贝森特将收益率飙升定性为暂时的“发烧”，于8月19日启动“扭曲操作”，通过增发超短期国债回购长期国债，甚至动用规模达1万亿美元的财政部一般账户（TGA）资金进行激进干预。
然而，贝森特的行政干预并未平息市场，收益率在9月9日回购加码后继续走高，暴露出政府误判了债券市场的核心矛盾。布伦特原油突破每桶100美元、全美柴油达到创纪录的每加仑6美元以上以及对美联储独立性的疑虑，固然放大了市场波动，但通胀预期与美联储信誉定价依旧相对稳定，证明短期外部冲击并非主因。真正的驱动力在于宏观结构性失衡：人工智能研发与落地引发了企业资本支出的爆炸式增长，巨额融资需求迫使资方索取更高风险溢价，而传统主权买家却在同步离场——中国因地缘冲突持续减持美债，海湾国家转向国内重建与供应链重组，日本抛售美债干预汇市，挪威主权财富基金亦在重新审视美债头寸。
当前债市绝非病态发烧，而是如同森林野火在通过提高资金成本进行“计划性烧除”，以便出清低效存量并为具备高生产率潜力的AI投资腾挪空间。贝森特的反复干预不仅无法改变供求现实，反而会扰乱美元定价、推高系统性金融风险并损害美债作为全球安全资产的信誉。正确的应对路径应是财政端实质性缩减赤字借贷，扭转对贸易、投资与结算体系的过度武器化以重新赢回收购方的信任。政策制定者必须正视收益率中枢抬升的现实，通过有序出清引导资本高效配置于创新基建，以此换取长期的增长韧性。
US government bond markets have experienced severe volatility, with ten-year Treasury yields rising from under 4.7% to breach 5%, while 30-year yields surpassed 5.35%, driving average 30-year mortgage rates above 7% and escalating domestic affordability anxieties ahead of midterm elections. With the national debt stock doubling to $40trn over the past decade, net interest expenses now consume roughly a fifth of federal tax revenues as Washington refinances maturing paper at borrowing costs unseen in two decades. In response, Treasury Secretary Scott Bessent diagnosed the spike as a temporary “fever,” launching an aggressive “twist” intervention on August 19th that deployed short-term debt and potentially tapped the $1trn Treasury General Account to conduct buybacks of long-duration bonds.
However, Treasury buybacks expanded on September 9th failed to halt rising yields, revealing that the administration misdiagnosed the structural foundations of the sell-off. While Brent crude climbing above $100 per barrel, domestic diesel exceeding a record $6 per gallon, and persistent questions surrounding Federal Reserve independence exacerbated market turbulence, stable long-term inflation pricing indicates these cyclical shocks are secondary. The decisive catalyst is a fundamental capital imbalance: enterprise investment in artificial intelligence has turbocharged the demand for debt financing, forcing bondholders to demand higher risk premiums. Crucially, this historic borrowing surge coincides with a structural retreat by traditional institutional buyers, as China divests amid geopolitical frictions, Gulf petrostates redirect capital domestically, Japan liquidates Treasuries to defend the yen, and Norway’s sovereign wealth fund re-evaluates its American exposure.
Rather than suffering a pathological fever, the bond market is executing a controlled burn to reallocate capital toward transformative, productivity-enhancing private-sector investments. Scott Bessent’s administrative market manipulations risk distorting price signals, debasing the dollar, destabilizing global finance, and degrading the haven status of Treasuries. Instead of suppressing yields, Washington must enact genuine fiscal restraint to curb federal borrowing and cease weaponizing trade and payment architectures that alienate foreign capital. Elevated Treasury yields should not be treated as a policy aberration, but rather as an essential structural repricing that must be accommodated to channel capital into sustainable, long-term technological productivity.
