When Manmohan Singh Became Governor of the Reserve Bank of India Dr. Manmohan Singh became the Governor of the Reserve Bank of India on December 16 1982. He served as RBI Governor from 1982 to January 14 1985. During his tenure every currency note issued bore his signature. Manmohan Singhs work as the Governor of the Reserve Bank of India was widely appreciated and it was during this time that he came into the limelight with the then-government. How Did Manmohan Singh Become Finance Minister? It was Alexandar who informed him that Narasimha Rao is planning to induct him in his cabinet as the Finance Minister. At that time Manmohan Singh was the Chairman of the University Grants Commission (UGC) and had no connection to politics. As a result he didnt take Alexanders words seriously. However Narasimha Rao was very serious about him. Narasimha Raos Trust Made Him Finance Minister An anecdote from June 21 1991 is mentioned in Manmohan Singhs daughter Daman Singhs book Strictly Personal Manmohan and Gursharan. On that day Manmohan Singh was at his UGC office when he was asked to go home get ready and attend the oath-taking ceremony. The book further adds that when the new team members were lined up to take the oath everyone was surprised to see Manmohan Singh among them. Although his portfolio was allocated later Narasimha Rao had already informed him that he was going to be the Finance Minister.
