US 30-year Treasury yield reportedly hits 5.50%, highest in more than 20 years

A September 25, 2026 post reported US Treasury yields of 5.08% for five-year bonds, 5.22% for 10-year bonds and 5.50% for 30-year bonds—up eight, 10 and 10 basis points, respectively. It described the 30-year yield as the highest in more than 20 years and cited rising oil prices and an “underwhelming” Treasury buyback operation as reasons for the increases. ZeroHedge also reported a six-basis-point rise in Japan’s 40-year government bond yield to 4.27%, below the 4.390% record it cited for May 19.
