The 10-year Treasury yield fell to 4.65% on Wednesday after the U.S. Treasury announced it will more than double the size of government debt buyback operations, a move aimed at easing pressure on long-term borrowing costs that had surged to levels unseen in nearly two decades.
Treasury Secretary Scott Bessent announced the department will increase the maximum size of buyback operations from $2 billion to at least $4 billion, with the change taking effect Sept. 9 through Nov. 4. The expanded program targets the 10- to 30-year segment of the Treasury market, which has experienced a sharp buyers’ strike since late June.
Yields had climbed sharply in recent months as inflation concerns, fiscal pressures, and increased corporate debt supply—particularly for artificial intelligence infrastructure—pushed investors to demand higher returns on government securities. The 30-year Treasury yield had reached 5.337% on Tuesday, its highest level since 2007, before the buyback announcement sent it tumbling nearly 10 basis points to around 5.19%.
The Treasury’s statement framed the expansion as a liquidity measure, saying the increase “reflects Treasury’s desire to provide greater liquidity support in longer-dated nominal sectors where there is consistent strong sponsorship from market participants.” In essence, by becoming a larger buyer of older, longer-duration debt, the government aims to encourage new buyers into a market that had seen heavy selling pressure.
Market analysts offered mixed assessments of the move. Krishna Guha, head of global policy and central bank strategy at Evercore ISI, noted that the buyback could “help crowd in potential buyers tempted by the prior run-up in yields and force some near-term short-covering.” However, he cautioned that the operation “changes almost nothing in terms of the fundamentals in particular the unchanged need to finance the tidal wave of hyperscaler debt in addition to very large government deficits.”
The intervention also drew scrutiny from some economists concerned about its broader implications. Joe Brusuelas, chief economist at RSM, argued that efforts to keep yields artificially suppressed could complicate the Federal Reserve’s inflation-control mission. Economist Mohamed El-Erian characterized the planned purchases as “small in both absolute terms and relative to net issuance,” suggesting they represent a broader deployment of yield curve control rather than a fundamental market solution.
Stock market futures surged following the announcement, signaling investor relief at the Treasury’s willingness to actively support the bond market during a period of substantial stress. President Trump later said he did not believe Americans should worry about the bond market’s condition.
