Comments from ECB Governing Council member Peter Praet at a conference at ULB university in Brussels:

“Precise figures are difficult to give because you have also to take into account the impact of your own policy on the functioning of markets,” Praet said. “The primary metric of success is the impact on inflation and inflation expectations.”

He also said the weaker euro and lower oil prices roughly balance each other out for now.

Nothing especially notable in the comments.
