Why can't the Fed lower interest rates below zero?
Because giving someone a loan and paying them to take it isn't a loan anymore.  I'll grant you, some of the treasury bill auctions did slip below 0% -- people paid in slightly more than what the bill would pay out. In as much as this was done by actual investors (and not afore-mentioned helicopter Ben Bernanke keeping the printing presses running hot all night), it was major accounts fearful of the euro disintegrating and banks crashing, and so on, and needing a safe spot to stick their cash for a couple months.  Where the Fed is concerned, that interest rate he's referring to is lending they do to banks. So, how much would you take if you ran a bank and the Fed offered to pay you to take their money? A billion? A trillion? As much as you could cram in your vaults, shove in your pockets, and stuff down your favorite teller's blouse? Yea, me too.
