Observing that the global financial crisis has exposed several limitations of conventional and unconventional monetary policy tools, Reserve Bank of India (RBI) Governor Shaktikanta Das on Friday said monetary economics in emerging markets needs a rethink.
This includes challenging the conventional wisdom of modern central banks to hike or reduce their interest rates by 25 basis points or multiples thereof, Das said in a special address delivered on the sidelines of the annual Spring Meetings of the International Monetary Fund and World Bank.
Highly appreciated by the audience for his call for out-of-the-box thinking to address monetary policy challenges of the 21st century, Das said the unconventional monetary policies of advanced economies have resulted in "risks and spillovers" for the emerging markets.
In his speech titled 'Global Risks and Policy Challenges facing Emerging Market Economies', Das observed that the global financial crisis has exposed several limitations of conventional and unconventional monetary policy tools.
In despair, some have turned to the heterodox evolution of ideas that are being practiced as modern monetary theory, he noted.
In the end, monetary policy must touch the real economy, spur investments, and maintain monetary and financial stability, he asserted.
The time has come to think out of the box, including by challenging the conventional wisdom, he told the packed auditorium.
Typically, modern central banks with interest rates as their main instrument move in baby steps -- 25 basis points or multiples thereof -- and announce a stance of tightening, neutrality or accommodation to guide the markets and the public on the likely future course of policy, he said.
"One thought that comes to my mind is that if the unit of 25 basis points is not sacrosanct and just a convention, monetary policy can be well served by calibrating the size of the policy rate to the dynamics of the situation and the size of the change itself can convey the stance of policy," the RBI Governor said.
For instance, if easing of monetary policy is required but the central bank prefers to be cautious in its accommodation, a 10 basis points reduction in the policy rate would perhaps communicate the intent of authorities more clearly than two separate moves -- one on the policy rate, wasting 15 basis points of valuable rate action to rounding off, and the other on the stance, which in a sense binds future policy action to a pre-committed direction, he said.
Likewise, in a situation in which the central bank prefers to be accommodative but not overly so, it could announce a cut in the policy rate by 35 basis points if it has judged that the standard 25 basis points is too little, but its multiple, that is 50 basis points, is too much.
"This approach can also be useful when the central bank is on a tightening mode and potentially help avoid policy turnaround from forward guidance via stance too far into the future, which in a highly volatile global scenario, may not even be a year," Das said.
Stating that management of global spillovers poses a formidable challenge to emerging market economies, Das told the audience that a truly global financial safety net remains elusive as in this age of mobile capital flows, consequences of their arrivals, sudden stops and reversals are to be borne nationally.
As a result, emerging market economies (EMEs) are typically at the receiving end when global spillovers flare up, he said, adding that they have no recourse but to build their own forex reserve buffers.
Paradoxically, the accumulation of reserves has become stigmatised, including with labels such as "currency manipulation", he rued.
"As I see it, we may be unintentionally setting the stage for several EME currencies to break out and challenge the hegemony of the dominant reserve currencies.
"There is a need for greater understanding on both sides. In the meantime, so far as the Reserve Bank of India is concerned, we will continue to play by the extant rules of the game," Das said in his special address.
Das also said central banks have to interact closely with financial markets for transmission of monetary policy impulses.
"In this context, ensuring a sound and efficient payment and settlement system is a pre-requisite," he noted.
