Duvvuri Subbarao, Reserve Bank of India Governor
A veteran of the finance ministry, Subbarao is perceived to be less independent of government influence than his predecessor, Y.V. Reddy. That may in part be because there has been little substantive difference between Subbarao and Mukherjee over how to manage through the global downturn.
Less voluble than Reddy, Subbarao has nonetheless occasionally caught the attention of markets with hawkish commentary that conflicts with government thinking, although his moves to tighten policy have been gradual and in line with government wishes.
Still, Subbarao, 60, appears keen to spring the odd surprise, such as raising bank reserve requirements more than was expected in January.
A career bureaucrat who served in Singh's economic advisory council in the Congress party's government's previous term, Subbarao worked closely with New Delhi to help steer the Indian economy through the global financial crisis.
Unlike some of his deputies, Subbarao is not given to making off-the-cuff remarks.
He is also seen to be taking steps to modernise the staid 75-year-old central bank, and recently held the RBI's first-ever conference call with analysts after the quarterly policy review.
