Marx’s discussion of crisis then moves from the fundamental contradiction in the commodity to money:
the crisis in its second form is the function of money as a means of payment, in which money has 2 different functions and figures in two different phases, divided from each other in time. Both these forms are as yet quite abstract, although the second is more concrete than the first.
To begin with therefore, in considering the reproduction process of capital (which coincides with its circulation) it is necessary to prove that the above forms are simply repeated, or rather, that only here they receive a content, a basis on which to manifest themselves.
Let us look at the movement of capital from the moment in
which it leaves the production process as a commodity in order once again to emerge from it as a commodity. If we abstract here from all the other factors determining its content, then the total commodity capital and each individual commodity of which it is made up, must go through the process C — M — C, the metamorphosis of the commodity. The general possibility of crisis, which is contained in this form — the falling apart of purchase and sale — is thus contained in the movement of capital, in so far as the latter is also commodity and nothing but commodity. From the interconnection of the metamorphoses of commodities it follows, moreover, that one commodity is transformed into money because another is retransformed from the form of money into commodity. Furthermore, the separation of purchase and sale appears here in such a way that the transformation of one capital from the form of commodity into the form of money, must correspond to the retransformation of the other capital from the form of money into the form of commodity. The first metamorphosis of one capital [must correspond] to the second [metamorphosis] of the other; one capital leaves the production process as the other capital returns into the production process. This intertwining and coalescence of the processes of reproduction or circulation of different capitals is on the one hand necessitated by the division of labour, on the other hand it is accidental; and thus the definition of the content of crisis is already fuller.
Secondly, however, with regard to the possibility of crisis arising from the form of money as means of payment, it appears that capital may provide a much more concrete basis for turning this possibility into reality. For example, the weaver must pay for the whole of the constant capital whose elements have been produced by the spinner, the flax-grower, the machine-builder, the iron and timber manufacturer, the producer of coal, etc. In so far as these latter produce constant capital that only enters into the production of constant capital, without entering into the cloth, the final commodity, they replace each other’s means of production through the exchange of capital. Supposing the [XIII-715] weaver now sells the cloth for £1,000 to the merchant but in return for a bill of exchange so that money figures as means of payment. The weaver for his part hands over the bill of exchange to the banker, to whom he may thus be repaying a debt or, on the other hand, the banker may negotiate the bill for him. The flax-grower has sold to the spinner in return for a bill of exchange, the spinner to the weaver, the machine manufacturer to the weaver, the iron and timber manufacturer to the machine manufacturer, the coal producer to the spinner, weaver, machine manufacturer, iron and timber supplier. Besides, the iron, coal, timber and flax producers have paid one another with bills of exchange. Now if the merchant does not pay, then the weaver cannot pay his bill of exchange to the banker. The flax-grower has drawn on the spinner, the machine manufacturer on the weaver and the spinner. The spinner cannot pay because the weaver [can]not pay, neither of them pay the machine manufacturer, and the latter does not pay the iron, timber or coal supplier. And all of these in turn, as they cannot realise the value of their commodities, cannot replace that portion of value which is to replace their constant capital. Thus the general crisis comes into being. This is nothing other than the possibility of crisis described when dealing with money as a means of payment; but here — in capitalist production — we can already see the connection between the mutual claims and obligations, the sales and purchases, through which the possibility can develop into actuality. mecw 32 140-42
