The European Central Bank is "not overly concerned" by the impact of inflation abroad on the bloc, the institution's President Christine Lagarde told CNBC.

The new Trump administration's policies may affect inflation in the United States but are unlikely to have much impact on price pressures in Europe, ECB policymaker Francois Villeroy de Galhau said on Wednesday.

European stocks are heading for a broadly positive open on Thursday as global markets focus on the inflation outlook. The U.K.'s FTSE 100 index is expected to open 13 points higher at 8,256, Germany's DAX up 44 points at 20,361, France's CAC up 8 points at 7,454 and Italy's FTSE MIB up 2 points at 35,210, according to data from IG.

The European Central Bank (ECB) is sticking to its guns on reducing inflation to 2% this year, even as Donald Trump’s return to the White House raises new uncertainty over global trade and economic stability.
