Global government bond markets broke from weeks of broadly synchronized trading on Thursday. U.S. Treasury yields fell as investors sought assets viewed as safe, while yields on French, Italian and Greek government bonds rose sharply. Fixed-income analysts and traders attributed the divergence in part to the unwinding of popular hedge-fund trades focused on Europe, adding complexity to the monthslong selloff in government bonds. Bond yields and prices move inversely, so falling Treasury yields indicate stronger demand for U.S. debt.
