Treasury Secretary Scott Bessent doubled long-end bond buybacks to at least $4 billion per operation on August 19, 2026, to signal that current yields do not reflect underlying fundamentals.

The announcement comes as U.S. Treasury yields reached a 19-year high of 5.34% earlier that day, a level that has prompted theories about intentional market positioning.

By increasing the volume of long-dated bond purchases, the Treasury aims to drag yields lower, a move that Decrypt reports also weakened the dollar.

Forbes notes that the doubling of buybacks is the central mechanism Bessent is using to address the rise in long-dated rates.
