Treasury Secretary Scott Bessent announced that the U.S. treasury Department will double its buybacks of older government bonds. This move has already narrowed the gap between 30-year Treasury yields and swap rates to its lowest point since February.
Scott Bessent's plan to double off-the-run bond purchases
The U.S. Treasury Department is aggressively expanding its program to repurchase longer-dated government securities to address market fragmentation. According to the report, Treasury Secretary Scott Bessent revealed that the department will double the current scale of its purchases specifically targeting "off-the-run" Treasury bonds—older issues that are less frequently traded than the most recent benchmark releases.
By swapping these fragmented, older holdings for larger, more liquid benchmark issues, the U.S. Treasury Department aims to reshape the supply curve. This strategic shift is designed to lower the overall cost of financing for the U.S. government while ensuring the Treasury can continue selling new securities to meet its ongoing fiscal requirements.
The 30-year Treasury yield and the February swap rate low
The immediate market reaction to the announcement was a tightening of the spread between the 30-year Treasury yield and its equivalent interest-rate swap rate.. As the report noted, this gap has shrunk to its narrowest level since February, suggesting that investors are no longer demanding as high a liquidity premium to hold and trade these government securities.
Despite this tightening, the underlying level of interest rates remains volatile and driven by external factors. for instance, the 30-year Treasury yield fluctuated following the announcement before closing near 5.2 percent on Wednesday, demonstrating that the market still prices these assets based on macroeconomic data rather than Treasury intervention.
Bank of America's 6-basis-point projection for 10-year yields
A recent study by Bank of America suggests that the Treasury's buyback program is primarily a tool for operational efficiency rather than a method for suppressing yields. Bank of America estimated that if the U.S. Treasury Department sustains this expansion through the end of 2028, it could provide roughly six basis points of support to the 10-year Treasury yield.
This move echoes a broader trend of government efforts to free up dealer balance sheets, which are often clogged by illiquid, older securities. By providing a reliable exit for these bonds, the U.S. Treasury Department reduces the difficulty of financing and selling older debt, which in turn improves the functioning of the broader bond market.
Why this is not yield-curve control or a formal rate ceiling
It is critical to distinguish the U.S. Treasury Department's actions from yield-curve control, a policy where a government commits to an unlimited purchase of securities to defend a specific interest rate. The report clarifies that Secretary Scott Bessent has made no such unlimited commitment, nor has the Treasury established a formal ceiling on yields.
Because this is a liquidity operation and not a price-fixing mechanism, long-term yields remain highly sensitive to inflation reports, oil price fluctuations, and Federal Reserve policy expectations. However, several questions remain: the report does not specify the exact funding source for these doubled buybacks, nor does it detail which primary dealers will be the main conduits for these transactions. Furthermore, it remains to be seen if the market will maintain this narrow swap spread if macroeconomic volatility spikes in the coming quarter.
