President Donald Trump said Treasury Secretary Scott Bessent expanded long-dated Treasury buybacks independently, praising his judgment on bonds and interest rates. The Treasury Department said on the 19th it would double the size of single-auction buybacks for 10- to 30-year Treasuries to at least $4 billion, briefly lifting bond prices and lowering yields. The effect quickly faded: on the 21st, the 10-year yield reached 4.737% and the 30-year yield 5.276%, as investors remained focused on the nearly $2 trillion U.S. fiscal deficit, rising national debt, inflation and heavy technology-company borrowing for artificial-intelligence infrastructure. Analysts questioned whether the policy treats symptoms rather than the underlying debt burden, while others warned it could shift pressure from bonds to the dollar or complicate the Federal Reserve's inflation policy. Bessent said the Treasury has more tools and that current yields do not reflect underlying fundamentals.
