Treasury Secretary Scott Bessent's ambitious plan to substantially expand the size of US debt buyback operations has hit a wall of market resistance.
On Wednesday, the Treasury Department announced it would raise the per-operation purchase cap for long-dated securities to $6 billion, tripling the previously planned amount from last month. However, this increased firepower failed to curb the ongoing selloff in the bond market. The 10-year Treasury yield touched a fresh three-year high during trading, with the downward pressure on prices actually intensifying following the release of the buyback statement.
Bessent has been explicit about making lower long-end yields a policy objective, yet current conditions are moving in the opposite direction. Elevated oil prices are stoking inflation concerns, market expectations for Federal Reserve rate hikes are building, and the fiscal deficit remains stubbornly high. These compounding pressures continue to push yields higher. The bond market's woes are now transmitting directly to the real economy, with US mortgage rates climbing to their highest level in more than a year.
Market Demands More as Shock-and-Awe Falls Flat
The decision to expand buybacks came after Bessent recently signaled the purchase cap could exceed $4 billion, fueling Wall Street expectations that individual operations might reach as high as $10 billion. Against that backdrop, the $6 billion ceiling has left many market participants disappointed.
"It's like the Treasury created a monster and now has to keep feeding it," said Steven Zeng, a strategist at Deutsche Bank. He noted that the $6 billion announcement failed to deliver the "shock-and-awe effect" investors had been hoping for.
Elias Haddad of Brown Brothers Harriman & Co. was even more blunt: "For now, the Treasury is bringing a pea shooter to a tank battle."
The chorus of calls for even larger buyback programs underscores just how stubborn long-end rates have become. Later on Wednesday, the Treasury auctioned $39 billion in 10-year notes at a yield of 4.834%, setting a record high for that maturity's auction history.
Bessent Acknowledges Limits on Shaping the Yield Curve
In the face of intense market reactions, Bessent himself conceded at a Texas event on Tuesday that he cannot alter the "equilibrium" price of Treasuries. His stated goal is merely to slow the pace of price swings and prevent harmful narratives from taking root and spreading.
He attributed the rapid rise in long-end yields to market fears that "America cannot repay its debts," calling such concerns "absurd, but they briefly became the dominant narrative."
Against this backdrop, Bessent has framed the expanded buyback program as a "Treasury Twist," drawing parallels to the Federal Reserve's historical Operation Twist, which was designed to lower long-term borrowing costs. He also argued that the buyback operations would help banks offload less-liquid securities, freeing up capacity for them to participate in new debt auctions.
Krishna Guha, head of economics at Evercore ISI, and his team wrote in a client note that Wednesday's announcement "shows Bessent is accepting the limited role of buyback operations" and that he "has likely realized the US cannot sustainably prevent fundamentals from dictating yield movements."
Multiple Conditions Needed to Push Yields Lower
Wells Fargo macro strategists Angelo Manolatos and Francis Brown noted in a research report that "additional catalysts are still needed to drive long-end yields lower." They cited several potential triggers: slowing growth and inflation, lower energy prices, reduced Fed policy uncertainty, fiscal consolidation, or a contraction in corporate bond issuance.
On the short-term policy signal front, the Treasury said Wednesday that the minimum cap for the remaining six long-dated nominal buyback operations this fiscal quarter would remain at $4 billion each, using language consistent with the surprise August 19 announcement, offering no clear indication of further expansion.
A Trump administration official, citing a Fox Business report, said the Treasury will routinely monitor the effectiveness of buyback operations and adjust their size as market conditions and liquidity needs dictate.
Worth noting is that the $6 billion figure is a ceiling rather than a guaranteed purchase amount. However, since the program was revived in 2024, the Treasury has completed full operations in 50 of 52 long-dated nominal buybacks, typically preferring to purchase up to the cap.
Deutsche Bank's Zeng also pointed out that the Treasury's "final buyback announcement" released at 11am can supersede the "preliminary announcement," meaning actual purchases could potentially exceed the stated cap.
Activist Intervention Style Sparks Debate
The surprise August 19 expansion announcement came outside the Treasury's regular quarterly communication window, catching investors off guard. It has also reignited discussion about whether US debt management is shifting toward a more "interventionist" style, a marked departure from the long-standing principle of "regular and predictable" operations.
Several investors and analysts interpret the increased buyback push as an externalization of the Trump administration's anxiety over rising long-term borrowing costs ahead of the November congressional elections. As Treasury yields continue to climb, US mortgage rates have risen to their highest level in over a year, delivering a direct hit to everyday consumers.
Bessent told Newsmax on September 1: "I'm making sure there won't be any major, serious adverse consequences." But judging by the current state of the bond market, this battle with the markets is far from over.
