Mario Draghi noted among others when speaking about the role of the ECB policy:

“The third concern about our policy is that it takes the pressure off governments to pursue structural reforms. But there are several problems with this argument.

For a start, it doesn’t work institutionally. It’s not the role of the ECB to use its monetary policy to force governments to reform. That’s not our mandate in the Treaty. And frankly, for us to act in that way would be totally illegitimate as unelected central bankers.”
