30-Year Treasury Yield Hits 5.34% — Highest in Nearly 20 Years

The U.S. 30-year Treasury yield reached 5.3371% on August 18, 2026 — its highest since the mid-2000s — before steadying near 5.28%. That sits roughly 175 basis points (one-hundredths of a percent) above the Fed's 3.75% policy-rate ceiling. Higher long-bond yields raise borrowing costs on mortgages and corporate debt and pressure stock valuations.
