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.
