One of these days, I’m going to write the king of all money creation posts and then I’ll be able to just link back to it for thread after thread…
I don’t see how this claim could be true by the official definition of the M1 stock of money.
Officially the M1 is currency out there in the world – that is currency outside of bank vaults – plus all checkable deposits. When a customer makes an outside deposit of currency, they’re bringing in money that’s placed in a bank vault, and therefore that currency disappears from the M1. Simultaneously a checkable deposit is created of the same amount, which increases the M1. The net change is nothing. Depositing currency does not actually expand the M1. It’s difficult to say whether “new money is created”. If you add up all the monetary base plus all the checkable deposits, the number is larger after a cash deposit, but that’s not how these things are typically measured.
But a loan clearly and indisputably does expand the M1, and it expands the M1 regardless of whether the loan check is deposited in full or whether some cash is taken out. After a bank approves a loan, they do some fiddling around with their accounting ledgers, and it looks something like this:
DEBIT New loan assetCREDIT New checkable deposit liabilityThe M1 consists of currency outside of bank vaults, plus checkable deposits. The new loan increased the amount of checkable deposits. There is no dispute about this, you can see it right there in the accounting entry. The new loan increased the stock of M1. It’s really as simple as that.
If the check is cashed, then the deposit for the loan is eliminated, but that also means that an equivalent amount of currency was withdrawn from a bank vault, so there’s no net change in the M1. That is to say that loans expand the M1 regardless of whether the money stays in the banking system, or whether it’s removed. That’s the simple fact of these definitions, which is very easy to get wrong. (I’ve gotten it wrong plenty of times before.)
The deeper problem is none of these definitions really matter on their own.
The definitions are only the first step. It’s a lot more important to know the reasons why the stock of money might increase, under what circumstances, how profitable these loans might be, how the central bank will react, and how fast money will flow through the economy for the purchase of new goods and services. Mastering a few formal definitions won’t provide any deeper understanding into the world of money. If we want to say anything sensible, we have to know how all the gears fit together.
