10-year Treasury yield briefly tops 5%, hitting its highest level since 2007 as bond-market selloff deepens

For the first time since October 2023, the 10-year Treasury yield surpassed the 5% mark on Monday, reaching an all-time high. The 30-year Treasury yield also climbed to 5.38% before retreating. This surge was driven by rising Brent crude prices, which hit a session high of over $109 a barrel, heightening inflation concerns and prompting investors to anticipate rate hikes ahead of the Federal Reserve's upcoming policy meeting.

Goldman Sachs revised its forecast for the week, shifting from no change to a rate increase following the August inflation report. While the report had limited impact on inflation expectations, it significantly boosted the probability of a rate hike to nearly 90%, raising concerns about potential market reactions if the Federal Open Market Committee (FOMC) remains on hold.

Some analysts believe that a rate hike this week could restore the Fed's credibility in fighting inflation and alleviate upward pressure on long-term yields. The global bond market trend is also evident, with 10-year yields in Australia and the UK both exceeding 5%. This rise in yields is not confined to the United States, indicating a broader market movement.

Despite the rise in yields, the stock market has continued its upward trajectory due to strong corporate earnings, which have outpaced bond market movements. Additionally, the unwinding of the yen carry trade, where investors borrow cheaply in Japan and invest in higher-yielding assets abroad, may be contributing to the global bond market selloff.

The rising yields also reflect governments and corporations issuing more debt to fund spending and develop AI infrastructure, increasing the supply of bonds available for investors.
