Recently, Reserve Bank of India (RBI) governor Shaktikanta Das speaking at the governor talks event on the sidelines of the Fund Bank Spring urged his counterparts across world to think “out of the box by challenging the conventional wisdom.” Das said, “One thought that comes to my mind is that, if the unit of 25 basis points is not sacrosanct and just a convention, monetary policy can be well served by calibrating the size of the policy rate to the dynamics of the situation and the size of the change itself can convey the stance of policy,” said the Governor. When it comes to interest rates as main instrument, the modern central banks move in baby steps i.e. 25 basis points or multiples, in order to announce a stance of tightening, neutrality or accommodation to guide the markets and the public on the likely future course of policy.
