The characteristic movement of capital in general, the return of the money to the capitalist, i.e., the return of capital to its point of departure, assumes in the case of interest-bearing capital a wholly external appearance, separated from the actual movement, of which it is a form. A gives away his money not as money, but as capital. No transformation occurs in the capital. It merely changes hands. Its real transformation into capital does not take place until it is in the hands of B. But for A it becomes capital as soon as he gives it to B. The actual reflux of capital from the processes of production and circulation takes place only for B. But for A the reflux assumes the same form as the alienation. The capital returns from B to A. Giving away, i.e., loaning money for a certain time and receiving it back with interest (surplus-value) is the complete form of the movement peculiar to interest-bearing capital as such. The actual movement of loaned money as capital is an operation lying outside the transactions between lender and borrower. In these the intermediate act is obliterated, invisible, not directly included. A special sort of commodity, capital has its own peculiar mode of alienation. Neither does its return, therefore, express itself as the consequence and result, of some definite series of economic processes, but as the effect of a specific legal agreement between buyer and seller. The time of return depends on the progress of the process of reproduction; in the case of interest-bearing capital, its return as capital seems to depend on the mere agreement between lender and borrower. So that in regard to this transaction the return of capital no longer appears as a result arising out of the process of reproduction; it appears as if the loaned capital never lost the form of money. To be sure, these transactions are really determined by the actual reproductive returns. But this is not evident in the transaction itself. Nor is it by any means always the case in practice. If the actual return does not take place in due time, the borrower must look for other resources to meet his obligations vis-à-vis the lender. The bare form of capital — money expended as a certain sum, A, which returns as sum A + 1/x A after a given lapse of time without any other intermediate act save this lapse of time — is only a meaningless form of the actual movement of capital.
