China’s Yield Curve Hits Steepest in Four Years on Oil Jitters

China’s government bond yield curve reached its steepest level in about four years, as inflation concerns triggered by the Iran war pile pressure on longer‑term debt.

The spread between the 10- and 30-year sovereign bonds’ yields widened by two basis points Monday to 52 basis points, the most since 2022, after a selloff that pushed yields higher across the curve, with longer maturities hit hardest.
