Treasury's Doubled Bond Buybacks Fail to Hold Down Long-Dated Yields

The United States Treasury tried this week to hold down yields at the long end of its own bond market. The market reversed the move within a day.

Treasury Secretary Scott Bessent's department said on Wednesday it would more than double the size of its liquidity support repurchases of longer-dated notes and bonds, to at least 4 billion dollars per operation beginning on 9 September. The announcement followed a week of sharp increases in the 30-year yield. The long bond initially fell 9 basis points to 5.196 percent, then reversed course on Thursday and traded near 5.234 percent, close to where it stood before the intervention.

The Financial Times argues that attempts to direct the bond market rarely hold, and that investors read the operation less as a technical liquidity measure than as a sign of official discomfort with the cost of long-term government borrowing. The underlying numbers support that skepticism. A buyback changes the maturity mix of federal borrowing. It does not reduce the deficit that creates the borrowing, and the Treasury separately confirmed that outstanding public debt has passed 40 trillion dollars for the first time.

Investors expressed the same doubt through other assets. Gold rose 2.03 percent on Friday to about 4,607 dollars an ounce, and bitcoin advanced roughly 20 percent across the week, a move Bloomberg reported as its largest weekly gain since March 2024. When the authority that issues the debt starts buying it back to manage its price, holders of that debt look for assets whose supply no policy committee controls.

The next test arrives quickly. The Kansas City Federal Reserve hosts its Jackson Hole symposium from 27 to 29 August, with Federal Reserve Chair Kevin Warsh, who took office in May, delivering his first keynote there on 28 August. Nvidia reports earnings in the same week, and the Economic Times notes that central bankers meet with inflation and elevated oil prices both live.
