Neutrality of money is a widespread if rather flawed assumption which underpins much of mainstream macroeconomics. Political economists disagree with this assumption due to the endogenous nature of monetary supply, encompassing reverse causation and exogenous interest rates.
It would be inappropriate to discuss neutrality of money or the rejection thereof without first discussing money itself. At its most basic, money is something deemed by an economy to have consistent numeraire value suitable for exchange and payment . In this way, a $50 note will always be considered, at least in its nation of origin, to be worth $50 in any transaction.

The orthodox approach is typically termed the metallist or M-form approach to money, wherein money is a numeraire, whilst Keynes aligned with the C-form or chartalist approach . …show more content…

Neutrality of money is almost universally disregarded by microeconomists but is typically accepted, at least in the long term, by most macroeconomists . Despite this, it is disregarded completely by almost all political
