 We are still not finished with this question: to what extent does the accumulation of capital in the form of loanable money-capital coincide with actual accumulation, i.e., the expansion of the reproduction process. The transformation of money into loanable money-capital is a much simpler matter than the transformation of money into productive capital. But two things should be distinguished here: 1) the mere transformation of money into loan capital; 2) the transformation of capital or revenue into money, which is transformed into loan capital. It is only the latter point which can involve a positive accumulation of loan capital connected with an actual accumulation of industrial capital. We have already seen that a large build-up or surplus of loan capital can occur, which is connected with productive accumulation only to the extent that it is inversely proportional to it. This is the case in two phases of the industrial cycle, namely, first, when industrial capital in both its forms of productive and commodity-capital is contracted, i.e., at the beginning of the cycle after the crisis; and, secondly, when the improvement begins, but when commercial credit still does not use bank credit to a great extent. In the first case, money-capital, which was formerly employed in production and commerce, appears as idle loan capital; in the second case, it appears used to an increasing extent, but at a very low rate of interest, because the industrial and commercial capitalists now prescribe terms to the money-capitalist. The surplus of loan capital expresses, in the first case, a stagnation of industrial capital, and in the second, a relative independence of commercial credit from banking credit based on the fluidity of the returns, short-term credit, and a preponderance of operations with one's own capital. The speculators, who count on the credit capital of other people, have not yet appeared on the field; the people who work with their own capital are still far removed from approximately pure credit operations. In the former phase, the surplus of loan capital is directly opposite to expressing actual accumulation. In the second phase, it coincides with a renewed expansion of the reproduction process it accompanies it, but is not its cause. The surplus of loan capital is already decreasing, i.e., it is still only relative compared to the demand. In both cases, the expansion of the actual process of accumulation is promoted by the fact that the low interest which coincides in the first case with low prices and in the second, with slowly rising prices increases that portion of the profit which is transformed into profit of enterprise. This takes place to an even greater extent when interest rises to its average level during the height of the period of prosperity, when it has indeed grown, but not relative to profit. We have seen, on the other hand, that an accumulation of loan capital can take place without any actual accumulation, i.e., by mere technical means such as an expansion and concentration of the banking system; and a saving in the circulation reserve, or in the reserve fund of private means of payment, which are then always transformed into loan capital for a short time. Although this loan capital, which, for this reason, is also called floating capital, always retains the form of loan capital only for short periods of time (and should indeed also be used for discounting only for short periods of time), there is a continual ebb and flow of it. If one draws some away, another adds to it. The mass of loanable money-capital thus grows quite independently of the actual accumulation (we are not speaking here at all about loans for a number of years but only of short-term ones on bills of exchange and deposits). That is to say, there is considerable fluctuation in that portion of the deposits which the bankers have not loaned out again, but which figures as their reserve and for the greater part also as the reserve of the Bank of England, where they are deposited. Finally, the same gentleman says: floating capital may be bullion, that is, bar and coin (503). It is truly wonderful how in this credit gibberish of the money-market all categories of political economy receive a different meaning and a different form. Floating capital is the expression there for circulating capital, which is, of course, something quite different, and money is capital, and bullion is capital, and bank-notes are circulation, and capital is a commodity, and debts are commodities, and fixed capital is money invested in hard-to-sell paper! By making advances to the bill-broker on bills of exchange which this broker has already discounted once, the banker does, in fact, rediscount them; but in reality, very many of these bills have already been rediscounted by the bill-broker, and with the same money that the banker uses to rediscount the bills of the bill-broker, the latter rediscounts new bills. What this leads to is shown by the following: Concerning this rediscounting and the assistance which this purely technical increase of loanable money-capital gives to credit swindles, the following extract from the Economist is of interest: This is how credits are "nicely" devoured. The rural depositor fancies that he deposits only with his banker, and fancies furthermore that when his banker lends to others, it is done to private persons whom he knows. He has not the slightest suspicion that this banker places his deposit at the disposal of some London bill-broker, over whose operations neither of them have the slightest control. We have already seen how large public enterprises, such as railways, may momentarily increase loan capital, owing to the circumstance that the deposited amounts always remain at the disposal of the bankers for a certain length of time until they are really used. Incidentally, the mass of loan capital is quite different from the quantity of circulation. By the quantity of circulation we mean here the sum of all the bank-notes and coin, including bars of precious metals, existing and circulating in a country. A portion of this quantity constitutes the reserve of the banks which continuously vary in magnitude. The variations in the interest rate (aside from those occurring over longer periods or the variation in the interest rate among various countries; the former are dependent upon variations in the general rate of profit, the latter on differences in the rates of profit and in the development of credit) depend upon the supply of loan capital (all other circumstances, state of confidence, etc. being equal), that is, of capital loaned in the form of money, coin and notes; in contradistinction to industrial capital, which, as such in commodity-form is loaned by means of commercial credit among the agents of reproduction themselves. However, the mass of this loanable money-capital is different from, and independent of, the mass of circulating money. For example, if 20 were loaned five times per day, a money-capital of 100 would be loaned, and this would imply at the same time that this 20 would have served, moreover, at least four times as a means of purchase or payment; for, if no purchase and payment intervened so that it would not have represented at least four times the converted form of capital (commodities, including labour-power) it would not constitute a capital of 100, but only five claims of 20 each. In countries with a developed credit, we can assume that all money-capital available for lending exists in the form of deposits with banks and money-lenders. This is at least true for business as a whole. Moreover, in times of flourishing business, before the real speculation gets underway when credit is easy and confidence is growing most of the functions of circulation are settled by a simple transfer of credit, without the help of coin or paper money. The mere possibility of large sums of deposits existing when a relatively small quantum of a medium of circulation is available, depends solely on: 1) the number of purchases and payments which the same coin performs; 2) the number of return excursions, whereby it goes back to the banks as deposits, so that its repeated function as a means of purchase and payment is promoted through its renewed transformation into deposits. For example, a small dealer deposits weekly with his banker 100 in money; the banker pays out a portion of the deposit of a manufacturer with this; the latter pays it to his workers; and the workers use it to pay the small dealer, who deposits it in the bank again. The 100 deposited by this small dealer have served, therefore, first, to pay the manufacturer a deposit of his; secondly, to pay the workers; thirdly, to pay the dealer himself; fourthly, to deposit another portion of the money-capital of the same small dealer; thus at the end of twenty weeks, if he himself did not have to draw against this money, he would have deposited 2,000 in the bank by means of the same 100. To what extent this money-capital is idle, is shown only by the ebb and flow in the reserve fund of the banks. Therefore, Mr. Weguelin, Governor of the Bank of England in 1857, concludes that the gold of the Bank of England is the "only" reserve capital: The actual or declared value of the exported products from Great Britain and Ireland in the prosperity year of 1824 was 40,396,300. With the crisis of 1825, the amount of exports then falls below this sum and fluctuates between 35 and 39 million annually. With the return of prosperity in 1834, it rises above the former maximum to 41,649,191, and reaches in 1836 the new maximum of 53,368,571. Beginning with 1837, it falls again to 42 million, so that the new minimum is already higher than the old maximum, and then fluctuates between 50 and 53 million. The return of prosperity lifts the amount of exports in 1844 to 58,500,000, whereby the peak of 1836 is again already far exceeded. In 1845, it reaches 60,111,082; it then falls to something over 57 million in 1846, reaches in 1847 almost 59 million, in 1848 almost 53 million, rises in 1849 to 63,500,000, in 1853 to nearly 99 million, in 1854 to 97 million, in 1855 to 94,500,000, in 1856 almost 116 million and reaches a peak of 122 million in 1857. It falls in 1858 to 116 million, rises already in 1859 to 130 million, in 1860 to nearly 136 million, in 1861 only 125 million (the new low is here again higher than the former peak), in 1863 to 146,500,000. Of course, the same thing could be demonstrated in the case of imports, which shows the expansion of the market; here it is only a matter of the scale of production. [Of course, this holds true of England only for the time of its actual industrial monopoly; but it applies in general to the whole complex of countries with modern large-scale industries, as long as the world-market is still expanding. F. E.] We will consider here the accumulation of money-capital, in so far as it is not an expression either of a stoppage in the flow of commercial credit or of an economy whether it be an economy in the actual circulating medium or in the reserve capital of the agents engaged in reproduction. Aside from these two cases, an accumulation of money-capital can arise through an unusual inflow of gold, as in 1852 and 1853 as a result of the new Australian and Californian gold mines. This gold was deposited in the Bank of England. The depositors received notes for it, which they did not directly redeposit with bankers. By this means the circulating medium was unusually increased. (Testimony of Weguelin, Bank Committee, 1857, No. 1329.) The Bank strove to utilise these deposits by lowering its discount to 2%. The mass of gold accumulated in the Bank rose during six months of 1853 to 22-23 million. The accumulation of all money-lending capitalists naturally always takes place directly in money-form, whereas we have seen that the actual accumulation of industrial capitalists is accomplished, as a rule, by an increase in the elements of reproductive capital itself. Hence, the development of the credit system and the enormous concentration of the money-lending business in the hands of large banks must, by themselves alone, accelerate the accumulation of loanable capital, as a form distinct from actual accumulation. This rapid development of loan capital is, therefore, a result of actual accumulation, for it is a consequence of the development of the reproduction process, and the profit which forms the source of accumulation for these money-capitalists is only a deduction from the surplus-value which the reproductive ones filch (and it is at the same time the appropriation of a portion of the interest from the savings of others). Loan capital accumulates at the expense of both the industrial and commercial capitalists. We have seen that in the unfavourable phases of the industrial cycle the rate of interest may rise so high that it temporarily consumes the whole profit of some lines of business which are particularly handicapped. At the same time, prices of government and other securities fall. It is at such times that the money-capitalists buy this depreciated paper in huge quantities which in the later phases soon regains its former level and rises above it. It is then sold again and a portion of the money-capital of the public is thus appropriated. That portion which is not sold yields a higher interest because it was bought below par. But the money-capitalists convert all profits made, and reconverted by them into capital, first into loanable money-capital. The accumulation of the latter as distinct from the actual accumulation, although its offshoot thus takes place, even when we consider only the money-capitalists, bankers, etc., by themselves, as an accumulation of this particular class of capitalists. And it must grow with every expansion of the credit system which accompanies the actual expansion of the reproduction process. If the interest rate is low, this depreciation of the money-capital falls principally upon the depositors, not upon the banks. Before the development of stock banks, of all the deposits in England lay in the banks without yielding interest. While interest is now paid on them, it amounts to at least 1% less than the current rate of interest. As for the money accumulation of the other classes of capitalists, we disregard that portion of it which is invested in interest-bearing paper and accumulates in this form. We consider only that portion which is thrown upon the market as loanable money-capital. In the first place, we have here that portion of the profit which is not spent as revenue, but is set aside for accumulation for which, however, the industrial capitalists have no use in their own business at the moment. This profit exists directly in commodity-capital, a part of whose value it constitutes, and along with which it is realised in money. Now, if it is not reconverted into the production elements of commodity-capital (we leave out of consideration for the present the merchant, whom we shall discuss separately), it must remain for a length of time in the form of money. This amount increases with the amount of capital itself, even when the rate of profit declines. That portion which is to be spent as revenue is gradually consumed, but, in the meantime, as deposits, it constitutes loan capital with the banker. Thus, even the growth of that portion of profit which is spent as revenue expresses itself as a gradual and continually repeated accumulation of loan capital. The same is true of the other portion, which is intended for accumulation. Therefore, with the development of the credit system and its organisation, even an increase in revenue, i.e., the consumption of the industrial and commercial capitalists, expresses itself as an accumulation of loan capital. And this holds true for all revenues so far as they are consumed gradually, in other words, for ground-rent, wages in their higher form, incomes of unproductive classes, etc. All of them assume for a certain time the form of money revenue and are, therefore, convertible into deposits and thus into loan capital. All revenue whether it be intended for consumption or accumulation as long as it exists in some form of money, is a part of the value of commodity-capital transformed into money, and is, for this reason, an expression and result of actual accumulation, but is not productive capital itself. When a spinner has exchanged his yarn for cotton that portion which constitutes revenue however for money, the real existence of his industrial capital is the yarn, which has passed into the hands of the weaver or, perhaps, of some private consumer, and the yarn is, in fact, the existence whether it is for reproduction or consumption of the capital-value as well as the surplus-value contained in it. The magnitude of the surplus-value transformed into money depends upon the magnitude of the surplus-value contained in the yarn. But as soon as it has been transformed into money, this money is only the value existence of this surplus-value. And as such it becomes a moment of loan capital. For this purpose, nothing more is required than that it be transformed into a deposit, if it has not already been loaned out by its owner. But in order to be retransformed into productive capital, it must, on the other hand, already have reached a certain minimum limit.
