Quote from jordanf:
Pretend I am in idiot (it should not be hard
). Forget the debt, getting back to inflation. Are you saying steep inflation can only be caused by a increase in the narrow money supply, and not the broad money supply? If so, why not?
There's two types of inflation.
One is price inflation, which is a result of supply and demand. This is the kind of inflation the Fed tries to control via influence of the broad money supply.
The other is monetary inflation, which refers to the narrow money supply. As the government monetizes additional debt the new dollars that are added will devalue the dollars that are already in existence.
The Fed can't control monetary inflation only the government can by paying down the national debt.
Out of control government spending, which could be exacerbated by high price inflation, would ultimately lead to hyperinflation and an eventual collapse of the currency.
It looks to me like the Fed has added 500 billion to reserves, seemingly by magic. What was the point of doing this? Isn't this so it is available to banks to now lend out, and possibly leading to up to 5T in additional (broad?) money supply? Wouldn't this lead to serious inflation?
The Fed increases bank reserves by purchasing Treasury securities from the member banks. The "out of thin air" part comes from the Fed creating a journal entry on the selling bank's credit side of the ledger.
You're right in that if the Fed didn't reduce the money supply in the future the excess reserves can result in price inflation.
Ultimately, when the Fed needs to reduce the money supply they do the reverse; sell the securities to the member banks and reduce their credit ledger entry.
That is, if they can. Price inflation can, and often is, the result of rising commodity costs; oil, etc.
Which is where the government's responsibility for controlling monetary inflation comes into play...
