Central banks have risen to positions of great power and responsibility in large developed economies. So much so that we watch their every move as if it has the potential to change everything. They not have planned on acquiring this "quasi-dominant policymaking position," as Mohamed El-Erian puts it, but this is where they are thanks to the global economic crisis. However, as El-Erian argues in a piece at Project Syndicate , they may lose their power quickly and with dangerous consequences if other policy making institutions (namely, elected leaders) don't stop relying on central banks to prop up economies, Comforted by the notion of a “central-bank put,” many investors have been willing to “look through” countries’ unbalanced economic policies, as well as the severe political polarization that now prevails in some of them. The result is financial risk-taking that exceeds what would be warranted strictly by underlying fundamentals – a phenomenon that has been turbocharged by the short-term nature of incentive structures and the lucrative market opportunities afforded until now by central banks’ assurance of generous liquidity conditions. By contrast, non-financial companies seem to take a more nuanced approach to central banks’ role. Central banks’ mystique, enigmatic policy instruments, and virtually unconstrained access to the printing press undoubtedly captivate some. Others, particularly large corporates, appear more skeptical. Doubting the multi-year sustainability of current economic policy, they are holding back on long-term investments and, instead, opting for higher self-insurance. Of course, all problems would quickly disappear if central banks were to succeed in delivering a durable economic recovery: sustained rapid growth, strong job creation, stable financial conditions, and more inclusive prosperity. But central banks cannot do it alone. Their inevitably imperfect measures need to be supplemented by more timely and comprehensive responses by other policymaking entities – and that, in turn, requires much more constructive national, regional, and global political paradigms. Having been pushed into an abnormal position of policy supremacy, central banks – and those who have become dependent on their ultra-activist policymaking – would be well advised to consider what may lie ahead and what to do now to minimize related risks. Based on current trends, central banks’ reputation increasingly will be in the hands of outsiders – feuding politicians, other (less-responsive) policymaking entities, and markets that have over-estimated the monetary authorities’ power.
