The yields on United States Treasuries with a remaining maturity of 10 and 30 years were on the rise on Monday, as continued tensions in the Middle East weighed on demand for government bonds. The ceasefire agreement between the United States and Iran is set to expire today, with no official confirmation yet that it will be extended. In addition, uncertainty surrounding the agreement continued to push crude oil prices higher, raising concerns that elevated energy costs could prolong inflationary pressures in the United States and keep inflation above the Federal Reserve’s target, potentially limiting the central bank’s room to cut interest rates and driving yields on government bonds higher. The yield on the 30-year bond rose 1.4 basis points to 5.280%, reaching its highest level since 2007. The return on the 10-year Treasury note climbed 1.0 basis point to 4.706%.
