Speculation was rife Sunday on who will succeed Raghuram Rajan as RBI Governor with over a dozen names doing the rounds, including that of Deputy Governor Urjit Patel, former CAG Vinod Rai and SBI chief Arundhati Bhattacharya.

Though there was no official word, the rumour mills were agog on who would be the next at the helm of the central bank, a day after Rajan made a surprise announcement that he was not interested in a second term and Finance Minister Arun Jaitley said a successor would be announced shortly.

Among the speculated names, Patel has been known as ‘inflation lieutenant’ of Rajan at RBI, while Bhattacharya’s tenure as SBI Chairperson also ends in September — the same month when Rajan would demit office.

Rai, the former Comptroller and Auditor General of India who is known to have flagged the 2G scam, is currently heading the newly-constituted Banks Board Bureau, set up to help the government appoint heads of public sector banks and advice on banking reforms.

The names doing the rounds also include Chief Economic Advisor Arvind Subramanian, World Bank Chief Economist Kaushik Basu, Revenue Secretary Shakatikanta Das, former Advisor to Finance Minister Parthsarathi Shome, BRICS Bank head and ICICI Bank veteran K V Kamath and Sebi Chairman U K Sinha.

Like Rajan, Sinha was made Sebi Chairman during the previous UPA regime but was given a surprise and rare extension by the NDA government in February days before his already extended tenure of five years was to end.

Other names being speculated are former RBI Deputy Governors Rakesh Mohan and Subir Gokarn, former Finance Secretary Vijay Kelkar, former CCI Chairman Ashok Chawla, former CEA Ashok Lahiri and noted economist R Vaidyanathan.

While most of these people could not be immediately contacted for their comments, Mohan said it is “premature to discuss” his candidature, while Bhattacharya had yesterday said that “Rajan is a person of very high caliber, who has built ably on the reputation of our central bank and given it a very large measure of credibility”.

Basu, also a former CEA, tweeted Rajan has been one of the finest central bank governors anywhere.

Rajan, who will have the shortest tenure as RBI Governor since liberalisation began in 1991, is also one of the few non-bureaucrats in this post as most of his predecessors had been IAS officers.

Traditionally, applications have never been invited for the post of RBI Governor unlike many other regulatory posts.
