This is because growth itself does not cause inflation; it is excessive utilization rates that are a proximate source of inflation pressures. We sometimes try to capture this by saying that monetary policy should foster the maximum sustainable growth that the economy is capable of achieving.
More precisely, once at full employment, monetary policy should accommodate the maximum growth that does not push the economy beyond that point. A monetary policy focused on maintaining price stability has to be careful to avoid stifling unexpected increases in trend growth, specifically by confusing higher trend growth with above-trend growth. In addition, monetary policy cannot accept responsibility for raising trend growth.
