RE: The goal of the central bank is to meet it's inflation target by injecting money into the economy via policies like QE.
Not really. QE was a semi-emergency move. The hope was that managing interest rates alone would be sufficient, but it turned out not to be for deep slumps. QE creates a lot of nasty side-effects and draws criticism to the Central Bank they'd rather not have. I think the chairman once said the job of stimuluses outside of interest rates was or should be Congress's job, not them. But Congress bungles it with debt and reverse Keynesian timing due to political and tax squabbles.
