US Treasury doubles long-dated debt buybacks to combat surging bond yields
The US Treasury is expanding its long-dated bond buyback program to inject liquidity and cap borrowing costs as public debt nears $40 trillion and geopolitical tensions drive yields to 19-year highs.
The US Treasury will double the size of its long-dated debt buybacks to battle surging bond yields. The expanded operation, increasing from $2 billion to $4 billion, applies to securities in the 10-year to 30-year segments and takes effect from September 9 to November 4.
The announcement followed a sharp bond selloff that pushed the 30-year Treasury yield to a 19-year high of 5.34 percent on Tuesday. Following the Treasury’s intervention, the 30-year yield retreated to as low as 5.187 percent, marking its largest daily drop since late June. The benchmark 10-year yield also declined by 6 basis points to 4.65 percent on Wednesday.
This tactical shift highlights growing concern over the economic pain of sustained high borrowing costs. Rene Albrecht, a senior analyst at DZ Bank, noted that policymakers fear yields above 5 percent because they raise interest expenses for both the government and the private sector. He added that the timing is sensitive, with midterm elections just three months away.
In a statement, the Treasury explained that the larger buybacks aim to provide greater liquidity support in longer-dated nominal sectors. The department cited consistently strong sponsorship from market participants, evidenced by the high volume of quality offers received in previous operations.
However, market professionals caution that the move is modest relative to the sheer size of the debt market. The additional $2 billion is small compared to the $32.2 trillion total Treasury debt market and the $5.5 trillion in outstanding 20-year and 30-year bonds.
Evercore ISI analysts described Treasury Secretary Scott Bessent as showing tactical skill by surprising bond shorts during a period of thin liquidity. Yet, the firm warned the operation changes almost nothing fundamentally, given the unchanged need to finance massive government deficits alongside a tidal wave of hyperscaler debt.
This marks the second time this month Bessent has intervened to counter adverse market moves, following an August 1 joint currency intervention with Japan to reverse the yen’s fall. Overall US public debt stood at $39.99 trillion on Monday and is poised to cross the $40 trillion threshold imminently.
Looking ahead, the Treasury has scheduled a repurchase of 10-year to 20-year securities for September 10, followed by a 20-year to 30-year buyback on September 24. These operations will contribute to a broader plan to repurchase up to $83 billion of securities across all maturities by early November, up from an initial $69 billion target.
