"We've said that the current level will help contribute to reaching our medium-term objective," Mersch said in an interview in Vienna late on Thursday.

Some negative news from markets was still expected, Mersch said, but he added that some normalization was returning and that "the beginning of a bottoming out in various market segments" could be seen.

"Looking into the future, there are still uncertainties and some other market segments are still suffering very strong disruptions," Mersch said.

"We'll have to expect some unpleasant news in various segments in the foreseeable future."

Mersch, also the Governor of the Central Bank of Luxembourg, stated that growth risks to the euro zone economy were on the downside and suggested that Q2 growth will slow slightly.

"We can't only rely on the first-quarter figures but need to look through them and acknowledge the fact that the second quarter will probably be slightly weaker," Mersch elaborated.
