The central bank today is not just the government’s bank, but also a bankers’ bank, a truly hybrid institution

The analytical tension in post-Keynesian thought between the theory of endogenous (credit) money and the theory of liquidity preference, brought to our attention by Dow and Dow (1989), can be viewed through the lens of the money view (Mehrling 2013) as a particular case of the balance between the elasticity of payment and the discipline of funding. Further, updating Fullarton’s 1844 “law of reflux” for the modern condition of financial globalization and market- based credit, the same money view lens offers a critical entry point into Tobin’s fateful 1963 intervention “Commercial Banks as Creators of ‘Money’” which established post-war orthodoxy, and also to the challenge offered by so-called Modern Money Theory.
