fluctuations must take place even with a purely metallic currency, but that they balance each other through their alternations; thus, e. g., an inadequate currency causes a fall of prices, the fall of prices leads to the export of commodities abroad, this export causes again an import of gold from abroad, which, in its turn, brings about a rise of prices; the opposite movement taking place in case of a redundant currency, when commodities are imported and money is exported. But, since in spite of these universal fluctuations of prices which are in perfect accord with Ricardo’s theory of metallic currency, their acute and violent form, their crisis-form, belongs to the period of advanced credit, it is perfectly clear that the issue of bank-notes is not exactly regulated by the laws of metallic currency. Metallic currency has its remedy in the import and export of precious metals which immediately enter circulation and thus, by their influx or efflux, cause the prices of commodities to fall or rise. The same effect on prices must now be exerted by banks by the artificial imitation of the laws of metallic currency. If gold is coming in from abroad it proves that the currency is inadequate, that the value of money is too high and the prices of commodities too low, and, consequently, that bank notes must be put in circulation in proportion to the newly imported gold. On the contrary, notes have to be withdrawn from circulation in proportion to the export of gold from the country. That is to say, the issue of bank notes must be regulated by the import and export of the precious metals or by the rate of exchange. Ricardo’s false assumption that gold is only coin, and that therefore all imported gold swells the currency, causing prices to rise, while all exported gold reduces the currency leading to a fall of prices, this theoretical assumption is turned into a practical experiment of putting in every case an amount of currency in circulation equal to the amount of gold in existence. Lord Overstone (the banker Jones Loyd), Colonel Torrens, Norman, Clay, Arbuthnot and a host of other writers, known in England as the adherents of the “currency principle,” not only preached this doctrine, but with the aid of Sir Robert Peel succeeded in 1844 and 1845 in making it the basis of the present English and Scotch bank legislation. Its ignominous failure, theoretical as well as practical, following upon experiments on the largest national scale, can be treated only after we take up the theory of credit.[151] So much can be seen, however, that the theory of Ricardo which isolates money in its fluent form of currency, ends by ascribing to the ebbs and tides in the supply of precious metals an influence on bourgeois economy such as the believers in the superstitions of the monetary system had never dreamt of. Thus did Ricardo, who proclaimed paper currency as the most perfect form of money, become the prophet of the bullionists.
