Physical cash: Cullen Roche versus Warren Mosler
Ralph Musgrave
I agree with some of the criticisms Cullen makes of MMT in his article “A critique of MMT, Modern Monetary Theory." However he goes off the rails in section 5 of that article.
First he says “In MMT all money is essentially state money.” Well that’s news to me: MMTers are well aware of the fact that commercial banks create a form of money when they extend loaans, aren’t they?
Next, Cullen criticises Warren’s ideas on the source of physical cash (dollar bills, etc.).
Warren says households cannot obtain physical cash unless the state has first spent state money into the private sector with the private sector then using that state money to purchase physical cash off the Fed. Cullen disagrees: he says all that’s needed is for commercial banks to create money, which occurs when a commercial bank extends a loan.
I’ll try to sort this one out, and may fall a*se over t*t in process, but nothing venture, nothing gained. For Cullen’s argument see the paragraph starting “A good example of the erroneous MMT position…”: that’s in section 5 of the article.
Warren says in effect that when a commercial bank needs $X of dollar bills, it orders them from the Fed and the Fed debits the commercial bank’s account at the Fed by $X. Correct.
Now the credit balances that commercial banks have at the Fed must have come from somewhere: they come from the state having first spent state money in to the economy.
Of course it would be POSSIBLE to have a system where the state spends no state money into the economy, and where, when a commercial bank wants physical cash worth $X it goes into debt to the Fed. But that’s not what happens in the real world: amongst other reasons because the Fed, like other central banks, charges punitive rates of interest to any commercial bank going into debt to the Fed.
So as far as the 2013 real world is concerned, Warren is in right: physical cash is in effect money which the state has created and spent into the economy.
But against that, Cullen says, “So the cash comes from the Treasury, but not through spending, but through the desire from someone who already has an inside money account to draw that account down. Again, inside money precedes outside money.” (I.e. he is saying that commercial bank created money precedes state money - physical cash in particular).
But hang on: Cullen himself admits in section 5 of his article that about 10% of money in circulation is state money. So there is plenty of state money sloshing around which the private sector can use buy physical cash off the Fed.
But Cullen likes to concentrate on the 90% of money which is commercial bank created. He says that for the most part, when the private sector gets physical cash, that comes about as a result of households and firms depositing collateral at commercial banks, and having their accounts credited, and then using a portion of that credit balance to get hold of physical cash.
Well that’s true, but it doesn’t alter the fact that when a commercial bank wants $X of physical cash from the Fed, the Fed debits $X to the commercial bank’s account at the Fed.
Hopefully that’s sorted out that argument.
Alternative banking systems.
As distinct from the banking and monetary system that actually exists in 2013, various other systems are perfectly feasible, as Cullen rightly points out. For example a system under which the only money in circulation is central bank created would be feasible: it’s called full reserve banking, and that system has plenty of advocates. And certainly, under that system, it would not be possible for anyone to obtain Fed created physical cash unless the state had first created and spent money into the private sector.
Conversely, there have been systems in the past where central banks were non-existent, yet there were thriving and efficient commercial banks, which issued their own bank notes. Those banks used gold to settle up with each other, though even precious metals aren’t essential since banks can settle up using almost anything: shares, real estate, you name it.
Those types of “central bank free” system existed in Scotland, Scandinavia and Canada between very roughly a hundred and two hundred years ago. George Selgin describes these systems in his various publications, including his book “The Theory of Free Banking”.
