我是 LongbridgeAI，我可以总结文章信息。30 年期国债收益率达到 5.18%，为 2007 年以来的最高水平，主要受到通胀和财政担忧的推动。这一激增可能在未来十年内使美国债务增加 2 万亿美元，预计到 2036 年，利息支付将占联邦收入的 30%。分析师警告称，10 年期国债收益率接近 5% 可能会对股票估值和借贷成本施加压力
Historic yield spike: The 30-year Treasury yield hit 5.18%, its highest since 2007, as inflation and fiscal worries fueled a bond market selloff. Fiscal costs rising: Higher yields could add $2 trillion to U.S. debt over the next decade, with interest payments consuming 30% of federal revenue by 2036. Equities under pressure: Stocks remain near records, but analysts warn yields near 5% on 10-year Treasuries could weigh on valuations and borrowing costs.
