It is primarily by raising interest rates that central bankers curb inflation, but an increase in interest rates takes up to two years to affect inflation  Accordingly, central bankers usually try to raise interest rates before inflation becomes excessive, at which time inflation is not yet readily apparent either  But unless inflation is readily apparent, interest rate hikes generally will be perceived as needlessly restraining a growing economy
Thus, central bankers' success in temporarily restraining inflation may make it harder for them to ward off future inflation without incurring the public' s wrath
It is a premise offered in support of the conclusion that central bankers' success in temporarily restraining inflation may make it harder for them to ward off future inflation without incurring the public's wrath.
