10-Year Treasury Yield Hits 4.72% as Middle East Conflict Fuels Global Bond Selloff

On August 18, 2026, the 10-year U.S. Treasury yield rose three basis points to 4.72% — a multi-decade high, per Swissinfo. Japanese and euro zone sovereign yields also hit multi-year highs, per Reuters. Brent crude climbed to $91.15. The renewed U.S.-Israel-Iran conflict erased May's ceasefire, reigniting oil-driven inflation. Higher yields raise borrowing costs on mortgages and business loans but boost returns on new savings and bonds.
