Subir Gokarn, chief economist for Asia Pacific with global rating agency Standard and Poor's, will be appointed as a deputy governor of the Reserve Bank of India (RBI), Finance Minister Pranab Mukherjee said here Wednesday. "It (the appointment) will be done in due course," Mukherjee said after a meeting with finance secretaries of states.

RBI has four posts of deputy governor, with one falling vacant after Rakesh Mohan quit in June. Usha Thorat, K.C. Chakrabarty and Shyamala Gopinath are the other three deputy governors. Before joining Standard and Poor's two years ago, Gokarn was chief economist with its Indian arm, Crisil.

He has also had a long spell with National Council of Applied Economic Research (NCAER), an economic think-tank.
