US Treasury Yields Hit Multi-Year Highs Amid Debt Fears
US Treasury yields surged toward 4.8% as investors reacted to rising federal deficits, AI-driven corporate borrowing, and inflation risks from the US-Iran conflict.
U.S. Treasury yields climbed to their highest levels since late 2023, with the 10-year note peaking at 4.818% and 30-year bonds hitting a 19-year high of 5.31%. This surge was triggered by a combination of hawkish signals from Kevin Warsh, Chair of the Federal Reserve, and rising energy costs following military escalation between the United States and Iran. Market participants have priced in a high probability of a Federal Reserve interest rate hike at the September 15-16 meeting to combat stubborn inflation.
Structural pressures have exacerbated the sell-off. U.S. national debt has surpassed $40 trillion, with the Congressional Budget Office projecting a fiscal year deficit of $2.1 trillion. Simultaneously, technology giants including Alphabet, Amazon, and Microsoft have issued billions in debt to fund AI infrastructure, increasing competition for capital. Treasury Secretary Scott Bessent attempted to stabilize the market by expanding bond buyback programs, but investors viewed these measures as insufficient to counter the massive supply of government and corporate debt.
Global trends mirror this instability, with yields spiking in Japan, Germany, and the United Kingdom. Foreign investors are increasingly shifting capital away from Treasurys toward U.S. equities, with Norges Bank Investment Management proposing a significant reduction in its Treasury holdings. Analysts warn that if yields breach the 5% psychological threshold, it could trigger a broad repricing of growth stocks and commercial real estate, while increasing borrowing costs for mortgages and auto loans.
