Central Banking Works Like a Cozy Compulsory Bank Cartel to Expand the Banks' Liabilities and the Banks Expand on a Larger Base of Cash in the Form of Central Bank Notes

But if banking is the cause of the business cycle, aren’t the banks also a part of the private market economy, and can’t we therefore say that the free market is still the culprit, if only in the banking segment of that free market? The answer is No, for the banks, for one thing, would never be able to expand credit in concert were it not for the intervention and encouragement of government. For if banks were truly competitive, any expansion of credit by one bank would quickly pile up the debts of that bank in its competitors, and its competitors would quickly call upon the expanding bank for redemption in cash. In short, a bank’s rivals will call upon it for redemption in gold or cash in the same way as do foreigners, except that the process is much faster and would nip any incipient inflation in the bud before it got started. Banks can only expand comfortably in unison when a Central Bank exists, essentially a governmental bank, enjoying a monopoly of government business, and a privileged position imposed by government over the entire banking system. . . .

Not that the banks complain about this intervention; for it is the establishment of central banking that makes long-term bank credit expansion possible, since the expansion of Central Bank notes provides added cash reserves for the entire banking system and permits all the commercial banks to expand their credit together. Central banking works like a cozy compulsory bank cartel to expand the banks’ liabilities; and the banks are now able to expand on a larger base of cash in the form of central bank notes as well as gold.

So now we see, at last, that the business cycle is brought about, not by any mysterious failings of the free market economy, but quite the opposite: By systematic intervention by government in the market process. Government intervention brings about bank expansion and inflation, and, when the inflation comes to an end, the subsequent depression- adjustment comes into play.
