EDITOR’S NOTE: While technical in nature, this Treasury announcement may be more significant than it first appears. Beginning September 9th, the Treasury will at least double the maximum size of its buyback operations involving longer-term U.S. government debt, including 10- to 30-year securities.
Treasury describes the move as an effort to improve market liquidity, not an emergency intervention or Federal Reserve-style quantitative easing. Still, the decision comes amid elevated long-term borrowing costs and warrants attention, particularly because Treasury says the increase will be at least double the current amount and plans to provide additional guidance in November.
The Lintonian is publishing the Treasury announcement below in full for readers who wish to examine it directly.

From the U.S. Department of the Treasury:
The U.S. Department of the Treasury is increasing, by at least double, the size of liquidity support buyback operations for longer-dated nominal coupon securities (the 10-year to 20-year sector and the 20-year to 30-year sector). The current maximum size of $2 billion per operation will be at least $4 billion per operation.
This change is effective September 9, 2026 and will be in effect for the remainder of this refunding quarter (through November 4, 2026). Treasury will provide more information about future buyback sizes at the next Quarterly Refunding, scheduled for November 4, 2026.
This increase in buyback operation sizes reflects Treasury’s desire to provide greater liquidity support in longer-dated nominal sectors where there is consistent strong sponsorship from market participants, as evidenced by the significant volume of high-quality offers Treasury routinely receives in longer-dated buyback operations.
An updated tentative Treasury buyback schedule will be released at a later date.
