30-Year Treasury Yield Climbs to 19-Year High of 5.274%

The 30-year U.S. Treasury yield rose 0.372 percentage points to 5.274% in August 2026 — a 19-year high, per WSJ. Sticky inflation and heavy bond supply drove a selloff hitting long-duration bonds hardest. That means steeper mortgage and borrowing costs for savers, and rising pain for bondholders holding long maturities.
