0645 GMT - Eurozone government bond yields open slightly higher, responding to an initial rise in U.S. Treasury yields following the Federal Reserve's well-anticipated 25-basis-point rate hike Wednesday. The rate hike, and perhaps more so the Fed's unanimous vote, increased global bond markets' trust in the Fed's resolve to return inflation to target. "The unanimous Federal Open Market Committee vote says more than the 25-basis point hike itself," CIFC Asset Management's Natalia Lojevsky says. Eurozone bonds might get some input from Spanish and French bond auctions on Thursday. The 10-year Bund yield rises 0.7 basis points to 3.510%, while the 10-year French OAT yield is up 1.2 basis points at 4.471%, according to Tradeweb.
