When the Fed now writes $85 billion of checks to buy Treasuries and mortgages every month, they really have nothing in the “bank” to back them. Supposedly they own a few billion dollars of “gold certificates” that represent a fairy-tale claim on Ft. Knox’s secret stash, but there’s essentially nothing there but trust. When a primary dealer such as J.P. Morgan or Bank of America sells its Treasuries to the Fed, it gets a “credit” in its account with the Fed, known as “reserves.” It can spend those reserves for something else, but then another bank gets a credit for its reserves and so on and so on. The Fed has told its member banks “Trust me, we will always honor your reserves,” and so the banks do, and corporations and ordinary citizens trust the banks, and “the beat goes on,” as Sonny and Cher sang. $54 trillion of credit in the U.S. financial system based upon trusting a central bank with nothing in the vault to back it up.
