Revision History

The U.S. 30-year Treasury yield surged past 5.19% on May 19, 2026, its highest level since July 2007, driven by persistent inflation concerns, tariff pass-through effects, and a Moody's credit downgrade. The move has broad implications: federal interest payments now exceed $1.2 trillion annually — more than defense or Medicare spending — while mortgage rates, corporate borrowing costs, and pension fund balance sheets all face pressure from the sustained rise in long-term rates.
