1223 GMT - High German government bond yields are driving up yields on euro-denominated investment-grade bonds, LBBW's Michael Kohler and Benedikt Horwedel say in a note. Rising public spending has caused Bund yields to rise, in turn pushing up euro IG corporate-bond yields, the analysts says. Ten-year Bund-yields climb 2.8 basis points to last trade at 3.162%.
