Italian and Spanish government bonds opened lower, increasing the additional yield investors demand to hold the securities instead of benchmark German bunds.
The yield on Italy’s 10-year bond rose six basis points to 5.51 percent at 7:45 a.m. London time. That pushed the yield spread to bunds 10 basis points wider to 3.81 percentage points. It reached 388 basis points, the most since Feb. 16.
Spain’s 10-year bond yield also increased five basis points, to 5.80 percent, with the spread to bunds widening to as much as 4.12 percentage points, the most since Nov. 30.
