U.S. Treasury yields reversed course on Thursday, with the 30-year bond yield rising roughly five basis points to around 5.25% and the 10-year note climbing to approximately 4.70%. The rebound erased most of the prior session’s decline that followed the Treasury Department’s unexpected announcement of expanded long-end buybacks.
On Wednesday, Treasury Secretary Scott Bessent’s department said it would increase the maximum size of liquidity-support buyback operations for 10- to 30-year securities from $2 billion to at least $4 billion per operation, effective September 9 through November 4. The move was framed as enhanced liquidity support rather than a formal shift in debt management, yet markets initially interpreted it as a signal of concern over elevated long-term borrowing costs that had reached nearly two-decade highs.
The subsequent yield decline supported equities, gold, and bitcoin. By Thursday, however, the impact faded as investors focused on the relatively modest incremental volume—estimated in the low tens of billions over the period—and on fresh inflation risks from higher oil prices. Analysts noted that the program’s effectiveness will depend on execution details and market conditions closer to the September start date.
The yield backup contributed to early pressure on stock indexes and rate-sensitive sectors. For fixed-income and equity investors alike, the episode illustrates both the power and the limits of administrative tools in influencing the long end of the curve when fiscal deficits, inflation expectations, and global capital flows remain dominant drivers.
