The 30-year Treasury yield surged as high as 5.286%, marking its highest level since August 18. This rise brings yields near levels seen before U.S. Treasury Secretary Scott Bessent's bond-market intervention last month, which had temporarily pushed yields lower. The impact of the intervention has proved short-lived, with the 30-year yield recently trading just below 5.26%, signaling renewed pressure on long-term U.S. borrowing costs.
