Did Ambedkar have a hand in creating the Reserve Bank of India?
He had a scholar's hand in the ideas behind it, and this is one of the more surprising items in his record. His London thesis, The Problem of the Rupee, analysed the failings of India's currency arrangements and argued for a system managed in India's own interest rather than for the convenience of sterling. When the Royal Commission on Indian Currency and Finance — the Hilton Young Commission — examined the question in the mid-1920s, his work was part of the material in front of it, and the central bank the commission's line of thinking helped bring about was established as the Reserve Bank of India in 1935.
It is worth stating the claim precisely. He did not draft the Reserve Bank of India Act and was not its author. What can be said with more confidence is that a trained economist's argument about how India's money should be managed fed into the debate from which the institution emerged.
The point for a reader who knows him only for caste is the range. The same person argued the technicalities of exchange rates and central banking and the abolition of untouchability, and did the first before the second made him famous.
