The Organization for Economic Cooperation and Development (OECD) said on Friday that the European Central Bank (ECB) should keep its quantitative easing over the coming two years.

"In fact, explicitly accepting that inflation could go beyond 2% over the next two years without triggering a tightening of monetary policy could make monetary policy more effective at influencing expectations, which is crucial when interest rates are at the zero lower bound," OECD said.
