Marx’s theory of money was integral to his analysis of capitalist dynamics. The rich potential of Marx’s analysis of money has, unfortunately, not received the attention it deserves both by political economists and by those who have been inspired by Marx’s political vision.

One problem is that Marx has for a long time been regarded simply as a “theoretical metallist” (Schumpeter 1954: 288). His highly abstract formulation of the origins of money in the commodity form, as “commodity-money,” has been seen as largely irrelevant to contemporary capitalism where money no longer takes the shape of a commodity like gold or silver but is tied/linked to the monetary liability of the state. But Marx’s copious notes from a wide array of sources from newspapers, journals like the Economist, to parliamentary reports on Commercial Distress and the Banking Act, are evidence that he engaged deeply not only with the monetary theorists of his time (including David Ricardo, Thomas Tooke and John Fullerton) but also with the concrete institutional workings and social foundations of the financial system. The precise link between money and the credit system in Marx’s framework thus needs elaboration.
