U.S. Treasury Ups Bond Buyback to $6 Billion

The U.S. Treasury Department will buy back $6 billion in government debt on Thursday, September 9, 2026. This amount exceeds the previously announced plan but sits at the lower end of Wall Street expectations, leaving traders unimpressed.

This is the first buyback operation since Treasury Secretary Scott Bessent said last month the department would at least double the size of its buybacks from an initial $2 billion. The new $6 billion figure is below the top range of dealer expectations, which ran from $6 billion to $8 billion.

Market Reaction and Analyst Views

Mike Lorizio, head of U.S. Rates and mortgage trading at Manulife Investment Management, said the market seemed underwhelmed. He suggested the lack of additional guidance on future operations would likely add more volatility. "The market is telling us this size of purchases didn't achieve it," Lorizio said, calling the announcement a "learning moment" for the Treasury.

The operation involves buying older, less active bonds in the open market and replacing them with short-term debt. This process can, at the margin, raise the price of remaining bonds and lower their yield.

Background of the Expanded Plan

Secretary Bessent surprised markets with the expanded buyback plan last month. He framed it as a response to a steep rise in 30-year Treasury yields, which eventually hit a 19-year high of 5.34%. Bessent claimed the move did not reflect fundamentals and that traders had "bad information." "We are trying to keep the market in equilibrium," Bessent said.

Analysts trace the sharp rise in bond yields to the aftermath of the Federal Reserve's July policy meeting. Many traders had expected a rate hike after tough talk on inflation from new Fed Chairman Kevin Warsh, but the central bank held steady.

Yields have since stabilized following Bessent's announcement and a subsequent speech by Warsh at the Jackson Hole symposium. In that speech, Warsh pledged to maintain the current measure of inflation and signaled he might favor a rate hike as soon as September 2026.

Economic Mechanics and Future Steps

Chris Low, chief economist at FHN Financial, analyzed the program's effect in a note. "In effect, the program has reduced long-term U.S. Debt supply and increased supply of shorter coupons," Low wrote. "This means the program is not reducing yields in general, but it is reducing some yields at the expense of others."

Analysts say a more effective way for the Treasury to manage long-end supply would be to cut the issuance of longer-term bonds. Such a move could happen at the Fed's next refunding announcement in early November.

The Treasury announcement comes ahead of a new $39 billion auction of 10-year notes. The benchmark 10-year Treasury yield edged up to 4.84% on Wednesday, September 8, a day after touching a new one-year high.

Broader Context of Treasury Activism

Secretary Bessent has taken increasingly activist measures over the past month. He recently intervened to support the Japanese yen, a move criticized by some economists. Adam Posen, president of the Peterson Institute for International Economics, said Bessent's posturing was ill-advised. In a Bloomberg Television interview, Posen argued that currency intervention either works by weakening the dollar and boosting domestic inflation, or it fails and makes the U.S. Look impotent.

The immediate focus, however, remains on the domestic bond market and the upcoming buyback operation.
