US 10-Year Treasury Yield Reaches Highest Since November 2023

Borrowing costs for homes, cars and businesses rose again Wednesday as the yield on the benchmark 10-year Treasury note climbed to 4.81 percent, its highest level since November 2023. The increase adds to pressure on mortgage rates, corporate financing and government budgets already stretched by large deficits.

Yields moved higher across developed markets. The 30-year Treasury yield reached 5.286 percent while the two-year note held near 4.4 percent. Germany's 10-year bund yield hit 3.375 percent, its highest since 2011. UK 10-year gilt yields extended to 5.25 percent and Australian 10-year bonds reached 5.198 percent. Japan's 10-year yield stayed above 3 percent for the first time in three decades.

Market participants linked the move to renewed inflation concerns after the latest escalation in Middle East tensions lifted oil prices. Federal Reserve Chair Kevin Warsh's recent remarks at Jackson Hole and Tuesday's EU inflation data have shifted pricing toward a higher chance of rate increases at the Fed's September 16 meeting and at the European Central Bank. US public debt has passed $40 trillion, or more than 120 percent of GDP. France's sovereign debt exceeds 3.5 trillion euros, about 117 percent of its GDP, and Japan's government debt stands at more than twice its annual economic output.

Additional supply from major technology companies funding artificial-intelligence projects has added to the volume of bonds competing for buyers. Dan Coatsworth of AJ Bell noted that investors now face an inflation outlook that may require larger rate hikes than previously expected. George Maris of Principal Asset Management said global debt levels are at stratospheric heights with no clear remedies in view. Charu Chanana of Saxo warned that the selloff could push the 10-year yield toward 5 percent before buyers return in force.

US stock benchmarks fell for a third consecutive session, and equity markets in Europe and Asia also declined.
