Bessent Treasury buybacks draw skepticism as long-term yields rebound

Bessent Treasury buybacks are facing an early test after long-term government-bond yields fell following a reported expansion plan, then moved higher the next day. For investors watching bonds, the key point is that Treasury Secretary Scott Bessent says the effort is about market liquidity, while analysts question whether it can ease pressure for long.

CNBC reported Aug. 20 that the Treasury Department said a day earlier it would at least double bond buybacks beginning in early September. The announcement initially pushed longer-term yields lower, according to CNBC, but those yields rose again Thursday as investors assessed the plan.

Bessent told CNBC that Treasury has a “big toolkit” and said the intervention was intended to support liquidity, rather than control the yield curve. A yield is the annual return investors demand to hold a bond, and it generally moves in the opposite direction of a bond’s price.

CNBC reported that Bessent said the buybacks could exceed $4 billion. Treasury has described buybacks in official materials as a debt-management operation: in February, it said repurchased securities are generally replaced with new issuance, meaning buybacks are not expected to materially change privately held net marketable borrowing.

What can Bessent do about Treasury yields?

CNBC identified several possible next moves, each with trade-offs. Treasury could increase the size or frequency of buybacks. Evercore ISI’s Krishna Guha called the reported plan a weak version of “Operation Twist,” referring to a Federal Reserve program that exchanged longer-term securities for shorter-term bills. Guha said the measure could have little lasting effect and might backfire if investors read it as concern about funding long-term debt.

• Reduce long-dated auctions: Treasury could sell less longer-maturity debt and issue more Treasury bills, which are shorter-duration securities. CNBC reported that Bessent had criticized that approach when it was used under former Treasury Secretary Janet Yellen.
• Shift the overall maturity mix: A broader move toward shorter-duration debt would extend the change beyond individual auctions. Guha warned that global investors can view heavier short-dated issuance as a sign of strain for sovereign borrowers, even if he said the U.S. differs from other issuers.
• Use tactical interventions: Market participants have used the term “Bessent put” for potentially unpredictable Treasury actions meant to discourage one-way bets against U.S. debt. Guha said that tactic could slow an overshoot in yields but may not determine where yields stand months later.
• Do nothing: CNBC also listed letting markets sort it out as an available choice.

The communication around any move may matter as much as its scale. Jefferies chief U.S. economist Thomas Simons said the reported buyback change came two weeks after Treasury’s quarterly refunding announcement, without an indication that buyback policy would change. He argued that this departed from Treasury’s regular-and-predictable communication practice and weakened confidence in its guidance.

Treasury’s own materials show why that criticism has resonance. The department has published third-quarter 2026 auction and buyback schedules as part of its quarterly refunding documents, and it said in 2024 that regular, predictable scheduling was part of its buyback framework. The department’s next formal refunding releases are scheduled for November, according to Treasury’s website.
