“9. … We know now that one of the main reasons of this failure [to maintain the exchange value of the rupee] is that our rupee circulation had before the closing of the Mints been increased to such an extent that it fully, and more than fully, supplied all the demands of trade, and allowed no room for any further addition in the form of gold. … The necessary condition of a fixed rate of [pg 292] exchange between two countries is that, when the currency of one of them becomes redundant as compared with that of the other, the redundancy may be relieved by the withdrawal, for a time, of the excess coin, and we wish, therefore, to reach the condition in which our circulating medium … is not composed wholly of silver coin which has no equal value outside the country, but contains also a margin of gold which is capable of being used elsewhere as coin, and will therefore in natural course flow to where it is most wanted. Our total rupee currency is estimated to be at present somewhere about 120 crores, to which we have to add 10 crores of fiduciary circulation of currency notes. “10. It is impossible with any exactness to say, and it can only be ascertained by actual experience, by how much this rupee circulation has to be decreased in order to remove its redundancy. … But some considerations point to the amount being within quite manageable limits. For example, there are twenty-four crores, more or less, of currency notes in circulation, including the amounts held in our Treasuries. If we could imagine that amount of circulation at present existing in the form of currency notes suddenly converted into £16,000,000 in gold, it seems impossible that Indian trade should be able to get on without having part at least of that amount held in actual circulation, in other words, it would not be possible for that amount of gold coin to be remitted out of the country without the value of the rupee being forced up to a point which would arrest the stream of export. If this is the case, twenty-four crores of rupees is the outside limit of the amount it might be necessary to convert into gold coin in order to introduce a stable exchange of 16d., accompanied by an actual (active or inactive) circulation of gold at that comparative value; and it is more than probable that the amount required may really fall far short of this.
