On the first trading day of 2026, U.S. Treasury bonds fell, with the yield on the 30-year Treasury note rising to its highest level since early September, as market optimism about the U.S. economic outlook dampened demand for safe-haven assets. The yield on the 30-year U.S. Treasury note climbed as much as 4 basis points to 4.88%, while the 10-year yield rose 2 basis points to 4.19%. This followed data showing that initial jobless claims in the U.S. fell last week to one of the lowest levels this year. Eugene Leow, a fixed-income strategist at DBS Bank, said the gradual rise in long-term yields may reflect growing optimism about the U.S. economy, a sentiment that stock markets may also be reflecting.
