NEWPORT BEACH – History is full of people and institutions that rose to positions of supremacy only to come crashing down. In most cases, hubris – a sense of invincibility fed by uncontested power – was their undoing. In other cases, however, both the rise and the fall stemmed more from the unwarranted expectations of those around them.
Over the last few years, the central banks of the largest advanced economies have assumed a quasi-dominant policymaking position. In 2008, they were called upon to fix financial-market dysfunction before it tipped the world into Great Depression II. In the five years since then, they have taken on greater responsibility for delivering a growing list of economic and financial outcomes.
