Treasury's expanded buybacks ease long-bond market friction, yields stay flexible

Treasury Secretary Scott Bessent's recent decision to at least double the buyback volume of long-dated government securities is already reflected in tighter spreads between 30-year Treasury yields and equivalent interest-rate swaps, the narrowest gap observed since February. This narrowing indicates that the purchases are lowering the extra yield investors require for Treasury-specific market frictions rather than imposing a ceiling on rates.

Bank of America’s analysis projects that, if sustained through 2028, the program could add roughly six basis points of support to the 10-year yield, with only about one basis point expected this year. The buybacks focus on older, less-traded off-the-run bonds, providing a regular outlet that eases dealer balance-sheet pressure and improves overall market liquidity. Unlike yield-curve control, the Treasury has not set a rate target or pledged unlimited purchases, allowing long-term yields to continue reacting to inflation, oil prices, and Federal Reserve expectations.

The 30-year yield hovered near 5.2 percent after a brief dip, underscoring that the market still determines rate levels. Overall, the initiative modestly enhances Treasury market functioning while preserving rate flexibility.
