Earlier quoted context omitted.
> Private banks create a good chunk of the new money that goes into circulation by issuing loans. Even this is misleading private banks do not "create" money. They add to the supply but do not create. For every loan credit there is an equal loan debit. The total amount of money, the sum of all credits and debits, is the exact same.
> The total amount of money, the sum of all credits and debits, is the exact same. Can't banks lend something like 7X more money than they have in deposits?
In theory a bank could create an infinite amount of money claims, at least up to the point where nobody wants any more at the interest rate offered. However, the bank is also subject to capital requirements which determine how much risk it can take relative to the amount of equity it has (this used to be called the “reserve ratio” but that is an outdated concept).
