Global bond markets are experiencing heavy selling as investors increase bets that the U.S. Federal Reserve (Fed) may need to raise interest rates again to tackle inflation risks that are not easing as quickly as expected. This selling pressure has pushed U.S. Treasury yields to multi-decade highs.
On Thursday, 24 Sep 2026 GMT+7, the 30-year U.S. Treasury bond yield rose to an intraday high of 5.501%, the highest since June 2004. Meanwhile, the 10-year yield jumped more than 10 basis points to 5.223%, the highest since June 2007. The 2-year yield also increased over 4 basis points to 4.941%.
This movement follows heavy selling on Wednesday when the 10-year yield surged the most in a single day since 7 Apr 2025 GMT+7, a period marked by market turmoil triggered by President Trump’s announcement of the "Liberation Day" import tax.
Bond prices and yields move inversely: when there is heavy selling of bonds, prices fall. Consequently, new buyers receive higher returns relative to the price paid, causing yields to spike when the bond market is sold off.
A key turning point is the market’s growing view that U.S. interest rates may need to be higher than previously expected, driven by several simultaneous factors.
First, strong economic data from the S&P Global Purchasing Managers’ Index (PMI) showed the U.S. economy expanding robustly, with inflationary pressures broadening.
Second, oil prices have approached $100 per barrel after President Trump signaled support for a ban on U.S. diesel exports, with Brent crude closing above $105 per barrel.
Third, Fed officials remain focused on controlling inflation. Fed Governor Michael Barr indicated additional policy tightening may be necessary to bring inflation back to target, while John Williams, President of the New York Fed, said the assumption of another rate hike by year-end is "reasonable."
According to CME Group’s FedWatch Tool on 24 Sep 2026 GMT+7, the market now assigns over a 75% probability of a rate hike at the October Fed meeting, up sharply from about 49% a week earlier.
Selling pressure is not confined to the U.S.; it has spread globally. Japan’s 10-year government bond yield hit its highest since August 1996, while yields on government bonds in the U.K., Germany, and other European countries also rose.
Mike Sanders, Head of Fixed Income at Madison Investments, said the current situation stems from multiple simultaneous pressures—including fiscal policy, economic factors, geopolitics, and supply-driven inflation—putting bond markets into unfamiliar territory. The recent yield surge cannot be explained solely by concerns over budget deficits.
U.S. bond yields are not just market figures; they serve as the "base price of money" in the global financial system, especially the 10-year Treasury yield, which influences costs ranging from mortgage rates to corporate financing. High yields therefore have cascading effects.
If markets believe the Fed must raise rates further or keep them elevated longer than expected, borrowing costs will likely remain high. Companies reliant on large investments or with significant debt will face higher interest expenses, impacting profits, investments, and future growth.
Additionally, when 10- to 30-year U.S. Treasury yields exceed 5%, investors reassess whether the additional risk of equities is justified. As yields rise, stocks and other risk assets must offer higher expected returns to attract capital.
Higher U.S. Treasury yields also boost demand for dollar-denominated assets. The U.S. dollar recently strengthened to an eight-week high, potentially pressuring capital flows, currencies, and stock markets in emerging markets including Thailand, though other factors also influence these trends.
Therefore, the market’s concern is not just that the 30-year U.S. Treasury yield has reached its highest since 2004, but that the world may face "prolonged high interest rates." If the Fed raises rates further, the impact will extend beyond bonds to borrowing costs, business investment, stock prices, currencies, and global risk assets.
