Rajan, who demits office after completing his 3-year term on September 4, said that half of the six-member monetary policy committee (MPC) are already in place and the government will name its nominees shortly.
With the setting of MPC, the interest rate setting powers would move from RBI Governor to the panel.
"I think there is some likelihood that the next decision will be made by the MPC rather than an individual. If that is the case, there would be six people sitting together and deciding what the path of interest rates will be. I think, we should expect them to take an independent decision and I am sure they will," Rajan said.
"The process has already started. It is not going to take a long long time to do that," he said at the customary post- policy press conference.

Out of six members of MPC, three will be from RBI -- the Governor, who will be the ex-officio Chairperson, a deputy governor and an executive director.
The other three members will be appointed by the central government, on the recommendations of a search-cum-selection committee, which will be headed by the Cabinet Secretary.
