Indian central bank governor says helicopter money no panacea

Euro zone and Japanese interest rates in negative territory have done little to help growth or inflation, causing some bankers and finance officials to speculate that policymakers will deploy "helicopter money", even though economists say it would be a last resort.

Widely credited with predicting the global financial crisis of 2008-2009, Rajan said the effectiveness of helicopter money was far from proven.

"It is not absolutely clear that throwing the money out of the window, or targeted checks to beneficiaries... will be politically feasible in many countries, or produce economically the desired effect," he said during a lecture at the London School of Economics.

"I am throwing the possibility out there that even helicopter money may not work for the same reason that so much fiscal spending has not elevated growth... So the nuclear option may not be as much of a panacea as some people think."

Policymakers have so far shied away from helicopter money, including the Bank of Japan governor and his French counterpart who said this week the European Central Bank was not discussing the measure and that it was not needed in the euro zone.

Rajan also said helicopter cash could have the opposite of the desired effect of encouraging recipients to spend. The more aggressive a measure was, the less understood its consequences, he added.

"Somebody getting this money and seeing the central bank governor throwing this money out of the helicopter, saying 'is this guy crazy? Has the world gone nuts? I am going to save this, because I am not sure what is going to happen'."

Rajan also said regulatory changes put in place after the global crisis, in particular steps limiting the amount of risk banks can carry on their books, could be making financial markets even riskier.

"We are better off today in terms of protecting the system but there are new risks we may have created...We have a very regulated banking system and in this situation, activity flows to the unregulated sector," he said.

"By moving activity across markets have we created potential for more risk? A situation where...banks are stronger but markets are weaker."

Rajan is a vocal critic of the unconventional monetary policies deployed by developed central banks, arguing that emerging markets suffered as a result, either in the form of huge capital inflows or their sudden withdrawal.

This has prompted discussions on whether the developing world could better coordinate policies. Rajan said such coordination was already underway on a smaller, regional basis but that more was probably needed.

"In the absence of the right kind of instruments on a global level, people need to work with each other and we need to figure out how to make this more part of the global structure," he said.

Rajan's term at the Reserve Bank of India ends in September though the government has the option of extending it by two years. Since taking charge in 2013, Rajan has stabilized the currency, almost halved double-digit inflation, and helped attract record levels of inward investment.

He declined comment on whether he would stay on the helm of the RBI if the option was offered.
