Bessent Doubles Long-Bond Buybacks as Yields Rebound

The Treasury Department, led by Secretary Scott Bessent, has moved to expand its support for the long end of the U.S. government bond market by increasing the size of its liquidity-support buyback operations. The maximum amount of longer-dated nominal coupon securities that can be repurchased in each operation will be at least doubled, with the ceiling raised from $2 billion to at least $4 billion.

These buybacks are aimed at easing pressures in longer-maturity Treasurys, where yields have climbed to levels not seen in years. By absorbing more outstanding debt in targeted operations, the Treasury is seeking to limit the rise of long-term borrowing costs and promote smoother functioning in key segments of the market.

Bond markets reacted swiftly to the announcement. Long-term Treasury yields initially dropped as investors reassessed the balance between supply and demand in light of the larger buyback capacity. The move briefly eased concerns about rising financing costs for the government and the broader economy.

However, that initial rally faded. By Thursday, the benchmark 10-year U.S. Treasury yield had climbed to about 4.704%, while the yield on the 30-year bond was around 5.24–5.25%. The reversal suggested that investors remained focused on broader forces driving yields higher, including expectations for economic conditions and term premiums.

Analysts and market participants have raised doubts about how much the enlarged buyback program can achieve relative to the size of the Treasury market and the structural pressures at the long end of the curve. The concern is that the operations, even at double their previous per-operation limit, may be too small to significantly shift long-term yield dynamics.

There is also unease that repeated or ad hoc interventions could complicate the Treasury’s long-held commitment to operate in a “regular and predictable” fashion. Critics caution that tactical buybacks may not resolve underlying challenges, such as persistent investor demands for higher compensation to hold long-dated debt, even if they temporarily influence trading conditions.

For investors, the expanded buyback capacity adds a new element to the landscape for trading and pricing long-dated Treasurys. The policy change signals a willingness by the Treasury to adjust its operations when market functioning comes under strain, even as it maintains large-scale issuance to finance government needs.

At the same time, the rebound in 10-year and 30-year yields after the initial announcement underlines that sentiment in the long end remains fragile. The mixed market response highlights the tension between near-term liquidity support and longer-term factors influencing borrowing costs, leaving open questions about how far such buybacks can go in reshaping the yield curve.
