...the paper currency in your purse or wallet is a liability of the Federal Reserve, legally speaking. After all, these green pieces of paper have "Federal Reserve Note" written on them. This is an accounting fiction, of course, a throwback to the days when the notes were simply claims to actual gold or silver. It's hardly a liability to have billions of dollars in "claims" against the Federal Reserve floating around, when they are claims to nothing. (If you tried to present a $20 bill for redemption at a Federal Reserve Office, you would be able to get two $10 dollar bills, or four $5 dollar bills, but certainly no other type of asset.)--HPBRW
