Treasury Announces Long-Bond Buybacks; 30-Year Yield Still Rising

On August 21, 2026, the Treasury pledged to buy back more long-term bonds to ease borrowing costs. The 30-year yield climbed over 3 basis points — hundredths of a percentage point — to 5.273%, near its highest since 2007. These yields anchor mortgages and corporate debt. Markets, so far, aren't buying it.
