30-Year Treasury Yield Climbs to 5.34%, Highest in Two Decades

The 30-year Treasury yield hit 5.3371% on August 18, 2026 — its highest since the mid-2000s — before settling near 5.28%. That's roughly 175 basis points (1.75 percentage points) above the Fed's 3.75% policy-rate ceiling. Higher long-bond yields push up mortgage and corporate borrowing costs while pressuring stock valuations.
