OK, here’s what I’m seeing.
If there were a completely static money supply new wealth would still be created and the ‘extra’ money to pay off the interest would come from deflationary (for lack of a better word) pressures on prices. This phenomena still exists under an inflationary monetary system hence the need for ‘price stability’, basically the whole justification for inflationary policy in the first place ignoring the obvious real reason for inflation.
This theory seems to ignore the price decreases, wealth increases and treat the economy as a zero-sum game.
Assuming that banks are fully capitalized at all times as long as the reserves sit on the Fed’s books that extra money that the banks create is always going to exist somewhere. It may get shifted around but as long as the Fed doesn’t take any reserves out of the system through selling assets someone, somewhere is going to FRB that money to remain fully capitalized.
Now you have the absolute minimum amount of money that can exist in the system, Fed reserves times the money created through FRB.
Lest we not forget the lesson of the day, leverage. Banks leverage their assets to create even more money that is backed by nothing at all, it just exists as a ledger entry in some accountant’s book. Which brings us to one of my favorite pet peeves, the velocity of money. This allows the limited amount of money to support the large amount of phantom money since it changes hands at a high enough rate to give the appearance of a much larger base of support for this inverted pyramid that we have created through magic beans.
If one were to create an evenly rotating economy out of this no money would ever leave or enter the system and all profits would be reduced to simple interest. If you were to add some economic growth prices would fall as the economy grew but still no money would enter or leave the system. If you then added monetary growth at a rate that equaled economic growth everything would stabilize at a ‘price stability’ level as all the ‘money is backed by GDP’ folks claim but money would still not leave the system nor would profits go above simple interest, assuming away the wealth redistribution nature of inflation.
If you were to take into account the wealth redistribution then the consumers’ levels of spending would eventually fall as the money was increasingly concentrated into the hands of the bankers and their big business allies but still no money would ever leave the system. It would also be safe to say that the overall consumer spending level wouldn’t necessarily have to fall but would just get shifted around but that would destroy the even rotation as does inflationary policies.
As a bit of an aside I never realized that an evenly rotating economy is impossible under an inflationary monetary policy…new ammunition to use against the monetarists methinks.
The only way I can see that money would ever leave the system is by the Fed decreasing reserves or for banks to de-leverage their investments and that’s just phantom money, the base is still fully intact. Normal economic activities wouldn’t cause this from what I understand.
But I admit that I’m pretty tired and could be completely wrong.
