This mode of measuring depreciation in terms of gold would be, relatively speaking, a harmless idea if it was not made the basis of another assumption on which the exchange standard is made to rest, that the general and specific depreciations of a currency are unrelated phenomena. As against this it is necessary to urge that the chief lesson to be drawn from this experience of the Bank of England for the benefit of the upholders of the exchange standard consists in demonstrating that although their movements are [pg 245] not perfectly harmonious, yet they are essentially interrelated. That lesson may be summed up in the statement that when the general depreciation of currency has taken place the occurrence of a specific depreciation, other things being equal, is only a matter of time, if the general depreciation proceeds beyond a certain limit. What will be the interval before specific depreciation will supervene upon general depreciation depends upon a variety of circumstances. Like the surface of a rising lake, general depreciation touches different commodities at different times according as they are located in the general scheme of things as determined by the relative strength of demand for them. If there is no demand for gold for currency purposes or for industrial purposes, the depreciation of the currency in terms of gold may be delayed. It is only to make foreign remittances that the demand for gold first makes itself felt, and it is there that specific depreciation primarily arises. But there again it need not, for everything depends upon whether other commodities equally good, which the foreigner would take as readily as gold, are forthcoming or not. Now, in the case of India all these three factors tending to postpone specific depreciation are more or less operative. The rupee is a full legal-tender currency and can effectively discharge debts without compelling resort to gold. The industrial demand for gold in a poor country like India cannot be very great.³⁷⁵ Consequently, the [pg 246] generally depreciated rupee does not show immediate signs of depreciation in the internal trade of the country. As for foreign payments, the position of India is equally strong, not because, as is absurdly supposed, she has a favourable balance of trade, but because she has certain _essential_ commodities which a foreigner is obliged to accept³⁷⁷ in place of gold. Specific depreciation of the rupee will occur chiefly when the general depreciation has overtaken the commodities that enter into India’s foreign trade. That the depreciation should extend to them is inevitable, for, as is well said, ³⁷⁵ The following table regarding the consumption of gold in different countries is interesting:— _Consumption of Gold (millions of pounds sterling at 85s. per fine ounce)_³⁷⁶
