Currency and interest accounted for one of the first advocates of Keynesianism and the
deepest concerns throughout their theoretical and practical activities. Publishing several economic
works, John Maynard Keynes addressed monetary issues throughout his entire work. Of all the
published works that give shape to the Keynesian thinking physiognomy, there are "Treaty on the
coin", "Treaty on Monetary Reform" and "General Theory". Apart of being a theory of the global
balance, Keynes‘s "General Theory" is a theory of the monetary balance. In order to understand the
mechanism of achieving Keynes’s monetary balance, it is necessary to make a brief incursion into
the elaborations of Knutt Wicksell and those of his followers at the Swedish School.
