If you take a $20 note to a shop, you can get goods and services in return. If you deposit it at a trading bank, they’ll pay you interest. But, if you take that note to the Reserve Bank, they will only give you another one in exchange. This says something about money as a signifier and its relationship with the figure of the sovereign. The irrational, brute force assumed by sovereign power is ultimately what backs the Reserve Bank (the bankers’ bank) and its power to issue notes that are ‘legal tender’. This guarantees the note’s command over goods and services – and hence over other people’s labour. On the one hand, the note is pure signifier, the signifier that stands for all other economic signifiers, the commodity of commodities (so to speak) that stands outside of the market for economic goods and services, and yet that forms the unity (the very unit of measurement) and liquidity of the market. This fact is even more obvious as money digitizes and becomes only virtual data. On the other hand, the note is pure object, a worthless excrement (no mistake that Freud saw money as symbolic of excrement), society’s most notorious objet petit a. It stands as a desired remainder and Master Signifier, symbolically outside and yet formative of the marketplace, and it operates not just as a ‘signifier of value’ but also as an object of (im)pure desire itself.
