How Banks Create Money From Nothing

Where does a dollar actually come from? Not the mint — almost none of the money in the economy is printed. The honest answer was set down, in plain English, by a central bank more than a decade ago, and almost no one has read it. What follows is a single dollar, traced back to the instant it was made.

What Happens When a Bank Makes a Loan?

The bill in your hand — the one from the last entry — is rarer than it looks. Add up every physical dollar in existence: every note in every wallet, register, vault, and mattress. The total comes to roughly a tenth of the dollars the country actually uses. The other ninety percent were never printed. They have no serial number, no cotton, no signature. They exist as entries in ledgers, and nowhere else.

So the bill answers a smaller question than it seems to. It tells you what a dollar is made of. It doesn't tell you where dollars come from. For that, the printing press is the wrong place to look. Almost no new money is made there.

Follow one of the ledger dollars back to its origin instead. Pick the most ordinary one imaginable — the money that funded a mortgage.
