Nirmal Jain, Chairman, IIFL Group. It\u2019s important to find a person of high credibility to replace Patel, he added. "This is the event that has happened. More important, than post mortem, is to watch who succeeds. It\u2019s very important at this stage, that government quickly finds a replacement with impeccable and high credentials to ensure continuity and stability", he said. \u201cThis was unexpected. The timing is also surprising as Governor continued after the contentious board meeting and also during the December monetary policy. This seems the culmination of the differences of opinion between government and RBI on a large range of issues. We had the feeling that the difference are bridging but today\u2019s event suggests otherwise. This will create uncertainty. Appointment of a credible governor quickly can dispel the situation", said Sujan Hajra, Chief Economist, Anand Rathi Financial Services.
