The 30-year U.S. Treasury yield broke 5.31%, reaching a new high in 19 years, while overseas major buyers withdrew, dragging down the U.S. stock market.

On August 17, local time, the 30-year U.S. Treasury yield exceeded 5.31%, reaching a nearly 19-year high. This wave of selling did not come as a surprise. Last week, the U.S. Treasury Department issued $25 billion in new 30-year bonds at a yield of 5.216%, the highest accepted yield for that maturity since 2001. Concerns among investors about the surge in the size of U.S. government debt, a significant increase in long-term bond supply, and inflation remaining above the Federal Reserve's target are continuously driving up long-end yields.
