Treasury Vows to Buy Back Long Bonds; 30-Year Yield Keeps Climbing

On August 21, 2026, the U.S. Treasury said it will buy back more longer-term bonds to curb rising borrowing costs. The 30-year yield rose over 3 basis points to 5.273% anyway — near its highest since 2007. The buyback targets yields that anchor mortgages and corporate debt. Markets, so far, are unimpressed.
