The U.S. Department of the Treasury said Aug. 19 it will at least double Treasury bond buybacks' per-operation size for 10–20 and 20–30 year securities, effective Sept. 9 through Nov. 4, 2026, to provide greater liquidity support amid rising long-term yields.
Operation Details and Timing
Treasury will increase the maximum size of its long-end liquidity-support buyback operations, raising the per-operation cap from $2 billion to at least $4 billion. This change applies to longer-dated nominal coupon securities in the 10–20 year and 20–30 year sectors. The adjustment takes effect Sept. 9, 2026, and remains in place through Nov. 4, covering the current quarterly refunding period. Treasury said it will provide more information on future buyback sizes at the next Quarterly Refunding scheduled for Nov. 4.
These buybacks repurchase older, less-traded “off-the-run” securities to improve market functioning rather than to finance new spending. Treasury described the increase as a response to strong market participation and significant volumes of high-quality offers in prior longer-dated operations.
The schedule includes a 10–20 year buyback on Sept. 10 and a 20–30 year operation on Sept. 24, with several additional buybacks planned through Nov. 4, including three extra 20–30 year and four more 10–20 year operations.
Market Reaction and Sizing
Following the announcement, long-term Treasury yields and the U.S. dollar declined, while shorter-term rates remained more stable. One report noted the 30-year yield fell about nine basis points to roughly 5.20%.
Analyses estimate the cap increase adds at least $14 billion of incremental liquidity support this quarter, raising maximum repurchases to about $83 billion. Before the change, scheduled liquidity-support buybacks totaled up to $38 billion.
The policy, attributed to Treasury Secretary Scott Bessent, aims to reduce longer-dated borrowing costs. Market participants emphasized that these buybacks serve as a market-functioning tool rather than a shift in issuance strategy. Some analysts noted that while larger long-end buybacks can reduce term premiums and improve trading conditions, their ability to reverse structurally higher borrowing costs is limited by supply and fiscal factors. The U.S. public debt stock, around $40 trillion, underscores the scale of borrowing pressures that repurchases alone cannot offset.
Treasury said in its statement, “This increase in buyback operation sizes reflects Treasury’s desire to provide greater liquidity support in longer-dated nominal sectors.”
Treasury will provide further details on buyback sizes at the Quarterly Refunding on Nov. 4, 2026.
