Seriously? Quantity of Money Theory?
People say that they 'know' that there is some direct, linear relationship between the credit or net money supply and
a) the general price level
and
b) foreign exchange rates
In fact, no such relationship exists, or has ever existed, in any mathematical form.
In fact, what we see from comparison charts is that even within the range of substantial movements in monetary aggregates, no such relationship can be identified, or even whether the effect is positive or negative.
The reality is that other factors (bank credit) completely swamp a 'money supply' factor.
If money supply could control inflation every central bank would have a money supply target.
None have.
Those that briefly tried (the Fed & the BOE) failed spectacularly.
