The US Department of the Treasury announced on Wednesday, August 19, 2026, that it will at least double the maximum size of its liquidity support buyback operations for longer-dated nominal coupon securities. The current maximum size of $2 billion per operation will increase to at least $4 billion per operation, effective September 9, 2026.
This increase in buyback operation sizes will be in effect for the remainder of this refunding quarter, which runs through November 4, 2026. The Treasury aims to provide greater liquidity support in the 10-year to 20-year sector and the 20-year to 30-year sector, where it has consistently received a significant volume of high-quality offers from market participants. Treasury Secretary Scott Bessent is seen as leading this effort to tamp down long-term Treasury yields.
The announcement led to a sharp decrease in yields, with the benchmark 10-year note falling 5.7 basis points to 4.647% and the 30-year "long" bond tumbling 9 basis points to 5.196%. Stock market futures also surged. The move is not a debt paydown but rather a rearrangement of the maturity schedule, and it is expected that the Treasury will fund these buybacks by issuing more short-term bills, thereby manipulating the yield curve.
Analysts have offered mixed reactions. Krishna Guha of Evercore ISI suggested the operation could encourage buyers and discourage future short-selling, while Joe Brusuelas, chief economist at RSM, criticized the move as a political act by Secretary Bessent that could complicate the Federal Reserve's inflation control efforts. Economist Mohamed El-Erian noted the purchases are small relative to overall issuance and could be seen as a form of "yield curve control." The strategy risks accelerating inflation and making the cost of financing the national debt more sensitive to interest rate increases, according to some bond traders and economists.
