This is the responsibility that a central bank should discharge. At the same time, in terms of monetary policy management, it is also a responsibility of a central bank to underline the fact that it has almost exhausted such conventional monetary easing measures as reducing nominal interest rates.
The reason I say this is because when listening to debate concerning monetary policy, we are somewhat puzzled that many seem to consider that interest rates can be further substantially lowered. Of course, even at the current level where nominal interest rates are virtually zero percent, we have managed to devise ways to create monetary easing effects. However, such efforts have obvious limits.
