The Treasury Department announced on September 9, 2026, that it will buy back up to $6 billion of government debt in an operation aimed at maintaining functionality in bond markets. This announcement triples the normal buyback operation and follows a statement from Treasury Secretary Scott Bessent on August 19, indicating that the department would at least double the normal amount for already-issued securities. Future operations are expected to be at least $4 billion.
The operation is intended to keep government debt markets liquid, specifically for 10- and 20-year notes. However, it has also been perceived as an effort to control Treasury yields, which have reached levels not seen since before the global financial crisis in 2008. Following the announcement, market reactions were negative, with Treasury yields rising but remaining volatile. Long-dated securities increased by as much as 5 basis points before easing.
The benchmark 10-year issue reached 4.841% around 11:30 a.m. ET, while the 20-year climbed to 5.314%. The 30-year bond also rose 5 basis points, surpassing the significant 5.3% level, yielding 5.307%. One basis point equals 0.01%.
Bond fund manager Mark Spindel, chief investment officer at Potomac River Capital, commented, "Hank Paulson's bazooka this is not," referring to the actions taken by the former Treasury secretary during the financial crisis. He noted that it required an act of Congress during that time.
Speculation prior to the announcement suggested that the buyback level could be significantly higher than the initial release, where Treasury indicated it would "at least" double the normal $2 billion operation. Robert Tipp, chief investment strategist and head of global bonds at PGIM Credit, stated, "At the end of the day, the Treasury is issuing a spectacular amount of securities, and they're trying to control the price level at the back end of the curve with really what, in the big scheme of things, is not necessarily a major operation."
The actual buybacks are scheduled to occur on Thursday in a 20-minute operation concluding at 2 p.m. ET. Higher Treasury yields have been influenced by several factors, including surging government debt that recently exceeded $40 trillion, inflation fears related to tariffs and the Iran war, and rising energy prices, with crude oil topping $100 a barrel on Wednesday.
Additionally, the long end of the Treasury curve is considered the less active segment of a market recognized as the deepest and most liquid globally. Treasury issuance this year has increased by 11.8% compared to 2025, with the $31.8 trillion in publicly held debt rising by 8.2%.
Mizuho economist Alex Pelle remarked, "Treasury announced buybacks less than hoped for (or feared depending on your point of view). The risk is that the Treasury ratchets this up in some manner given the market's reaction. However, I think the pressure to go against standard operating procedure will abate somewhat on the other side of the midterms."
Critics of the accelerated buybacks have questioned their potential impact on such a large market, as well as the deviation from Treasury's typical operational predictability. Stanley Druckenmiller, head of Duquesne Family Office and a former mentor to Bessent, expressed concern in a Wall Street Journal op-ed, stating, "Once markets believe Treasury is defending a price, every rise in yields becomes a test of official resolve, and the operations must grow to survive the tests. Governments defending prices against fundamentals always lose. The only variable is how much they spend before conceding."
Treasury's actions, which also include a parallel move to support the Japanese yen, come as Federal Reserve Chairman Kevin Warsh has advocated for less involvement in financial markets. The Fed is expected to make a rate decision in a week, with traders anticipating a hike. Anil Kashyap, a University of Chicago economist, stated, "Actions not words are what matter, and action in this case means changes in the direction of fiscal policy or interest rates."
