The intervention reversed the selloff within hours, sending the 10-year yield as low as 4.63% before it closed at 4.65%. The selloff had intensified since the outbreak of the Iran war, pushing the 10-year yield up nearly 70 basis points and lifting 30-year mortgage rates to around 6.75%. The buyback marks the most aggressive step yet in Secretary Scott Bessent’s campaign to bring down long-term borrowing costs. But the move also shifts more government borrowing into short-term bills, deepening tensions with the Federal Reserve and raising the risk that inflation stays sticky even as the national debt held by the public reaches $32.2 trillion.
How the Bond Buybacks Work
Treasury buybacks are formally designed to improve liquidity for less-traded maturities. Newly issued debt trades with healthy demand, but older securities — known as off-the-run bonds — can become illiquid. A 30-year bond issued in May 2020, with 24 years left to maturity, traded Wednesday at roughly 45 cents on the dollar. Removing these instruments from the market frees up institutional balance sheets to buy more liquid issues, which puts downward pressure on rates.
The Treasury is not retiring debt or conducting quantitative easing. “The Fed can print money and buy what they want,” said Brij Khurana, fixed-income portfolio manager at Wellington. “The Treasury doesn’t have that capability. They need to fund the buybacks by issuing more bills.”
That funding mechanism is where the strategy becomes controversial. Rather than replacing long-term bonds with long-term bonds, Treasury is expected to issue more short-term bills to finance the repurchases — effectively manipulating the yield curve. The Treasury did not specify in its announcement how it would fund the buybacks and did not respond to requests for comment.
Short-Term Debt Already Above Advisory Ceiling
Treasury bills already make up 22.2% of outstanding government debt, above the roughly 20% ceiling recommended by the Treasury Borrowing Advisory Committee, an apolitical group of market experts. Scott Bessent himself criticized his predecessor, Janet Yellen, in 2024 for the same practice of leaning more heavily on T-bills, calling it an attempt to keep down the costs of overspending.
The TBAC has also cautioned against politicizing buybacks. In July 2025, the committee said repurchases would be acceptable if aimed at fixing liquidity problems but warned against using them to alter the debt profile — the balance between longer and shorter maturities. “The Committee feels strongly that issuance is the primary tool for managing the debt profile,” its minutes recorded.
Pressure on Chairman Kevin Warsh
The buyback adds to a series of moves that effectively curb long-term Treasury yields. In July, Bessent used Treasury funds to support Japan’s yen but sold euros rather than dollars, and urged the Federal Reserve to expand a facility allowing Japan to lend rather than sell its Treasury holdings. On August 5, Treasury said it would continue issuing relatively more short-term debt.
President Donald Trump has demanded the Fed cut interest rates to ease the debt burden while simultaneously adding to it. The federal budget deficit is on track to hit $2.1 trillion this year, according to the Congressional Budget Office. The government has already paid $963 billion in net interest in the first 10 months of fiscal year 2026, with debt service accounting for about 15% of fiscal spending.
“We’re slowly moving to the point where the logic of populism is going to insist that the central bank support fiscal objectives,” said Joseph Brusuelas, principal and chief economist at RSM US. “That will cause market distortions. And the sort of intervention that we saw this morning that will make life more difficult for Kevin Warsh.”
Warsh, who as a commentator criticized the Fed’s bond purchases for enabling overspending, may face questions at the Jackson Hole symposium about how he sees the Federal Reserve’s relationship with the Treasury and the bond market.
What Happens Next
The buyback’s success in tamping Treasury yields could embolden further interventions, but the strategy carries two clear risks. First, tilting more debt toward short maturities makes interest costs more sensitive to Fed rate decisions — if Warsh raises rates to fight inflation, government interest expenses would climb rapidly. Second, suppressing long-term rates could stimulate economic activity and keep inflation elevated, forcing the Federal Reserve to hold rates higher for longer.
The dollar already fell nearly 0.8% against a basket of currencies after the announcement, a signal that markets view the intervention as a form of financial repression. Watch for Warsh’s Jackson Hole remarks for any indication of whether the Fed will push back against Treasury’s yield management or accommodate it. Also watch the next TBAC meeting for whether the advisory committee escalates its warnings about the debt profile and the politicization of bond buybacks.
