Have Treasury bond buybacks failed to hold down long-term yields?
Core argument: The 30-year Treasury yield reached 5.27% on Tuesday, the level seen moments before Scott Bessent announced an expanded buyback program on August 19, erasing the decline that followed.
The yields on the longest-dated US government bonds shot back to levels seen just before Scott Bessent shocked markets last month by expanding a buyback program in an effort to halt the rise. The gambit worked briefly, until the selloff that’s been sweeping through global markets pushed the government’s borrowing costs up again. By Tuesday, that drove 30-year Treasury yields to 5.27%, the level seen moments before Bessent announced the move on August 19. The 10-year yield — a crucial benchmark for the cost of all types of loans — is more than 10 basis points higher than it was then, at roughly 4.8%.
