U.S. mortgage rates and Treasury yields experienced significant upward pressure through late 2026. ~~On September 30, 2026,~~ In early September, the 10-year ~~U.S.~~ Treasury yield ~~hit~~ climbed to 4.85% amid persistent inflation and a ~~24-year high, briefly reaching 5.304%.~~ federal debt exceeding $40 trillion. Geopolitical tensions in the Middle East further fueled inflation fears by pushing Brent crude oil above $100 per barrel. By mid-September, the 10-year yield surpassed the 5% threshold following the Federal Reserve’s first interest rate hike in three years. This surge was driven by ~~stronger-than-expected economic growth~~ a combination of high government deficits and massive capital expenditures for artificial intelligence infrastructure. Analysts noted that ~~outweighed softer inflation data. Following this peak, yields began to retreat~~ as ~~market expectations for further Federal Reserve interest rate hikes diminished. However,~~ yields ~~remained elevated during~~ rose, the ~~week ending October 2, with~~ cost of capital increased for AI-related companies, particularly smaller neo-cloud providers. For example, CoreWeave reported that every 1% increase in interest rates could raise its floating-rate debt interest expenses by approximately $30 million. On September 30, the 10-year yield hit a 24-year high, briefly reaching ~~5.3% and the 30-year yield hovering around 5.6%.~~ 5.304%. While weak nonfarm payroll ~~data—showing only 29,000 jobs added against an expected 84,000—briefly~~ data briefly triggered a relief rally, yields quickly reversed course as the unemployment rate rose to ~~4.2%, exceeding the expected 4.1%.~~ 4.2%. By October 3, the 10-year yield climbed to 5.342%, marking its highest level since 2002. Analysts attribute this surge to several compounding factors: the massive issuance of debt required to fund the U.S. budget deficit, large technology companies utilizing the bond market to fund artificial intelligence and data center investments, and persistent inflation. Thierry Wizman of Macquarie has argued that the volume of bond issuance may be a more primary driver of current trends than inflation alone. On October 8, a $39 billion auction of 10-year T-Notes yielded 5.30%, marking the highest yield for this maturity since November 2000. Despite these high costs, foreign demand remained robust. By mid-October, U.S. stock markets showed resilience despite bond market volatility, with the S&P 500 reaching a record closing value. This occurred even as the 10-year Treasury yield climbed to 5.33%. By October 10, yields reached further highs driven by 5.342%. Following a hawkish policy shift from Federal Reserve Chair Kevin ~~Warsh. Following remarks at Jackson Hole and a September rate hike,~~ Warsh, markets ~~are pivoting~~ pivoted toward an aggressive tightening ~~cycle, with inflation projected~~ cycle. However, by October 22, yields experienced a broad decline as the 10-year yield fell to ~~remain above target until 2029.~~ 4.97%, marking its first drop below 5% since late September. This movement was driven by a flight to safety following a sharp selloff in technology stocks, as investors rotated capital into Treasuries amidst concerns regarding AI spending and capital scarcity.
