US 10-Year Yield Hits 5% Despite Treasury Buyback Push

The 10-year Treasury yield reached 5% on September 18, defying federal buyback efforts and signaling persistent pressure on borrowing costs.
Key points
- The 10-year Treasury yield reached 5% on September 18, up from near 4% earlier in the year.
- Treasury plans to buy back at least $4 billion in long-term bonds monthly, totaling over $30 billion by November.
- Average 30-year mortgage rates stood at 6.95% on September 18, reflecting the high long-term bond yields.
The 10-year Treasury yield climbed to 5% on September 18, marking a significant rise from levels near 4% in early spring. This increase occurred despite the Treasury Department's recent announcement to double its long-bond buybacks. The move signals that market forces are currently overpowering government intervention efforts.
Treasury Secretary Scott Bessent aims to lower yields by increasing debt repurchases, with plans to buy at least $4 billion per month. However, the strategy has failed to curb rising rates so far. Investors remain unconvinced by the administration's attempts to control the bond market through these purchases.
Market Resistance to Buyback Strategy
The September 9 announcement of a $6 billion buyback operation did not stabilize the $32 trillion bond market. Oil price surges and growing budget deficits continue to drive lenders to demand higher compensation. The iShares 20+ Year Treasury Bond ETF reflects this pressure with a 3.2% negative return this year.
Strategists cited persistent above-target inflation and high corporate borrowing as key drivers of the sell-off. These factors outweigh the impact of government purchases in the eyes of many market participants. The Treasury's approach fails to address the core demand for higher yields from lenders.
Rising Costs for Borrowers and Investors
Mortgage rates track the 10-year yield, resulting in an average 30-year fixed rate of 6.95% on September 18. The Federal Reserve raised its benchmark rate by a quarter point on September 16, its first hike in three years. This action further complicates the Treasury's ability to lower long-term borrowing costs.
Higher bond yields make fixed-income investments more attractive relative to equities. This shift can reduce capital flowing into the stock market, potentially pressuring prices downward. Investors seeking lower borrowing costs may face continued disappointment as yields remain elevated.
Implications for Future Debt Management
The upcoming November 4 refunding update will test the efficacy of the current buyback strategy. If the 10-year yield holds near 5% despite increased purchases, it confirms market dominance over government policy. The Globe and Mail notes that this outcome suggests borrowing costs will likely continue to rise.
