Robert P. Murphy does not understand fiat money

In “Let There Be Money” Robert P. Murphy shows that he does not really understand money. And he gets fiat money specially wrong.

He states that “the market’s classic commodity moneys have been displaced by unbacked State-issued paper”. State-issued paper is not unbacked: it is inconvertible or irredeemable, but it is backed by the assets in the Central Bank’s balance sheet; the quality of the backing may be low, but it is not zero. And paper notes are only a fraction of State-issued liabilities used as money: there are also private bank deposits at the Fed.


Here Murphy is right and he himself proves it: his analysis of fiat money is incorrect and he has a faulty understanding of how money works.

Fiat money is unique to a coercive State because that is what fiat means: by State order, decree, law or sanction. It helps to know some latin.

Commodity money is not the opposite of fiat money, and vice versa. A commodity can be fiat money it the State so decrees and manages to enforce that legal tender law.


And before that and after that, an ounce of gold was, is and will be an ounce of gold. That is not saying much.


The minting process is not the essential phenomenon. The production of liabilities of a central bank, whatever their form, is.

Privately issued, voluntary fiat monies are theoretically possible.

No, they are not, because they imply a contradiction.


Hayek did not call private currencies fiat money. Bitcoin is not fiat.


Fiat implies that the coercion of the State is essentially involved somehow. It does not imply that the State has infinite powers and can always achieve what it intends.

Murphy quotes Mises, who does not get it right either:


Actually, legal tender laws can do more than that: they can decree that a certain kind of money must or may be accepted for all or some payments (like taxes). Maybe the State is not powerful enough to have that law be respected, or maybe it is. And maybe the State does not need to be omnipotent, perhaps it only needs to provide a marginal advantage to some means of payment.


So legal tender laws complicate the issue, and the issue is so complicated that Murphy seems not to understand it. Some Austrians love arguments of the type of “it is possible that”: they do not specify how probable it is “that next Tuesday, nobody will want to hold US dollars anymore”. Fiat currencies do not fail randomly: they fail when they are badly mismanaged and when the State loses all or part of its coercive power.

We can at least imagine privately issued fiat money.

If we have a deeply defective illogical imagination, then yes we can!

Murphy does not even mention one of the main differences between moneys or means of payment: whether they are assets that are nobody’s liability (like a physical commodity or an abstract entity like bitcoin) or if they are assets that are somebody’s liability (credit money, someone’s promises to pay money, debt used as money).

It is possible to consider fiat central bank notes as non-liability money, but it must be done in a way that they can also be considered liability money. In order to understand this apparently paradoxical issue you need good knowledge of money, debt and banking.
