"In today's world where China has USD 4 trillion in foreign exchange reserves, USD 354 billion is not enough in case an exchange rate-related issue breaks out," Basu, who was the chief economic advisor to the finance ministry in the UPA government, said during a lecture at IIT Bombay.
The comments come within two days of Reserve Bank Governor Raghuram Rajan allaying market concerns, saying we have a strong forex reserves to fight any external stress arising from the present turmoil in the market following the crisis in the Chinese economy.
Basu, however, said we have not entered a phase of "competitive devaluation or a currency war where what you do is you lower your exchange rate to try and give a boost to your exports."
"I think as far as possible you must resist competitive devaluation," Basu said.
"Overall on exchange rate policy, my suggestion will be roughly what used to be done till 2008, when we accumulated foreign exchange reserves," he added.
