Expanding money supply may be expressed in the host’s equity market – and/or any other sector(s) of its asset markets. It could also escape into consumer price inflation. Or it could actually be used for productive investment. The point is that if money supply is expanding faster than the fundamental economy, the excess supply will find a home.
This is a theme we shall explore in more detail at another time. For now wanted to explore a variant of this concept with respect to the equities market – the idea that the equities market can get ahead of the real economy when risk appetite and expanding money supply conspire to juice things up:
This chart isn’t so simple to read given that the absolute range of outcomes – on the face of it we are sitting in the middle of the long term range. It also doesn’t take into account the substitution of equity for debt (and vice versa) that is one of the objectives of our analysis. A better interpretation perhaps is that provided by relative market capitalisation. I’m still on the hunt for raw data but in the meantime consider this chart from The Chart Store (via The Big Picture):
