美国10年期国债收益率升至4.568%,30年期突破5%,市场已排除今年降息可能。与此同时,AI行业正进行现代资本市场史上最大规模的债务发行周期,超大规模企业资本支出将超6000亿美元,美国五大科技巨头的自由现金流35年来首次转负。核心问题在于,科技巨头每年约4000亿美元的AI基础设施支出与AI实际约1000亿美元的收入之间存在巨大缺口。若收益率持续高企,再融资将成严峻挑战,例如Alphabet在24小时内发行了320亿美元债券,而Oracle的信用违约互换自9月以来已翻三倍,债务风险值得密切关注。
The 10-year US Treasury just hit 4.568%, highest in 10 months.
The 30-year is back above 5%. Inflation is re-accelerating, markets have fully priced out any Fed rate cut this year, and some are now betting on a hike.
Meanwhile, the AI industry is running the largest debt issuance cycle in modern capital markets history. Hyperscaler capex is set to cross $600B this year. Free cash flow for the top five US tech spenders is turning negative for the first time in 35 years. This buildout is funded by bonds.
The problem: the gap between what Big Tech is spending on AI infrastructure (~$400B/year) and what AI is actually generating in revenue (~$100B) is massive.
