More specifically, if monetary policy is enacted with a view to fostering bank lending generally, it would make little sense to use macro-prudential tools to restrict bank lending generally as well.
On the other hand, carefully targeted macro-prudential measures do have a role to play in tackling any undesired side-effects of monetary policy in specific sectors or markets: think, for example, of a real estate market bubble in any particular country of the euro area. We have had many examples of measures enacted to that effect in Europe recently.
