Raghuram Rajan, Governor of the Reserve Bank of India, writes: As the world struggles to recover from the global economic crisis, the unconventional monetary policies that many advanced countries adopted seem to have gained widespread acceptance. In those economies, however, where debt overhangs, policy is uncertain, or the need for structural reform constrains domestic demand, there is a legitimate question as to whether these policies’ domestic benefits have offset their damaging spillovers to other economies. More problematic, the disregard for spillovers could put the global economy on a dangerous path of unconventional monetary tit for tat. To ensure stable and sustainable economic growth, world leaders must re-examine the international rules of the monetary game, with advanced and emerging economies alike adopting more mutually beneficial monetary policies.
To be sure, there is a role for unconventional policies like quantitative easing (QE); when markets are broken or grossly dysfunctional, central bankers need to think innovatively. Indeed, much of what was done immediately after the collapse of US investment bank Lehman Brothers in 2008 was exactly right, though central bankers had no guidebook. But problems arise when these policies are extended beyond repairing markets; the domestic benefits are at best unclear when economies are deeply damaged or need serious reform, while the spillovers from such policies fuel currency and asset-price volatility in both the home economy and emerging countries.
Officials at multilateral institutions have not questioned these unconventional monetary policies, and have largely been enthusiastic about them. This approach carries fundamental risks: a breakdown of the rules of the game and the fact that source countries’ are unwillingto take spillovers into account causes unintended collateral damage in recipient countries.
Central banks could recognize adverse spillovers explicitly and minimize them. The threat posed by competitive monetary easing matters to everyone. In a world with weak aggregate demand, countries are engaging in a futile competition for a greater share of it. In the process, they are creating financial-sector and cross-border risks that will become increasingly apparent as countries exit their unconventional policies. The first step to prescribing the right medicine is to recognize the cause of the illness. And, when it comes to what is ailing the global economy, extreme monetary easing has been more cause than cure. The sooner we recognize that, the stronger and more sustainable the global economic recovery will be.
