Bernanke, however incompetent he seems to be regarding even some basic economic theory, is correct when he says:
We’re not printing money.
The amount of currency in circulation is not changing.
The money supply is not changing in any significant way.
– Ben Bernanke, 60 Minutes Interview, December 2010
Even Quantitative Easing (which Bernanke, being a typical bureaucrat, wants to rename to “Credit Easing”) is not adding to the REAL money supply in any significant way.
This is because money supply is Quantity times Velocity, and Bernanke imagines that he’s adding only enough money to make up for the dramatic loss in velocity that has occurred for the past three years.
The massive addition of money by Fed lending was not added to circulation at all…it’s ended up stagnating in the banks’ reserves.
The reason for this is that the Fed started paying interest on banks’ reserves (an insane thing to do) in 2007.
Remember, the money the Fed “creates” is not real money at all…it is temporary money. People worry that when the economy recovers and velocity returns to a normal level, we’ll be trapped with this huge amount of extra money, but in fact the Fed is lending money that has to be paid back with interest, NOT simply giving away money. The money that is paid back is “destroyed” in the same sense that it was “created”.
What’s more, the Quantitative Easing money is added by buying financial instruments like bonds and notes…and when the Fed thinks the economy is recovering, it intends to SELL those instruments, and destroy the money.
There is a MUCH more detailed, clearer explanation here:
