The convertibility of the sovereign into rupees at the Rs. 15 to £1 ratio is not laid down, therefore, in any Act whatever. It depends on Notifications withdrawable by the Executive at will. Further, the management of the Gold Standard Reserve is governed neither by Act nor by Notification, but by administrative practice solely; and the sale of Council Bills on India and of sterling drafts on London is regulated by announcements changeable at administrative discretion from time to time. All this emphasises the gradual nature of the system’s growth, and the transitional character of existing legislation. As matters now are, there is something to be said for a new Act, which, while leaving administrative discretion free where there is still good ground for this, might consolidate and clarify the position. 9. As a result of these various measures, the rupee remains the local currency in India, but the Government take precautions for ensuring its convertibility into international currency at an approximately stable rate. The stability of the Indian system depends upon their keeping sufficient reserves of coined rupees to enable them at all times to exchange international currency for local currency; and sufficient liquid resources in sterling to enable them to change back the local currency into international currency, whenever they are required to do so. The special features of the system, although, as we shall see later, these features are not in fact by any means peculiar to India, are: first, that the actual medium of exchange is a local currency distinct from the international currency; second, that the Government is more ready to redeem the local currency (rupees) in bills payable in international currency (gold) at a foreign centre (London) than to redeem it outright locally; and third, that the Government, having taken on itself the responsibility for providing local currency in exchange for international currency and for changing back local currency into international currency when required, must keep two kinds of reserves, one for each of these purposes. I will deal with these characteristics in successive chapters. It is convenient to begin with the second of them and at the outset to discuss in a general way the system of currency, of which the Indian is the most salient example, known to students as the _Gold–Exchange Standard_. Then we will take the first of them in Chapters III. and IV. on _Paper Currency_ and on the _Present Position of Gold in India and Proposals for a Gold Currency_; and the third in Chapter VI. on the _Secretary of State’s Reserves_.
