How Banks Actually Make Money

There's a question about your mortgage I couldn't answer for almost a year, even sitting inside the bank. When I finally could, I understood the whole machine.

Here's the question. When a bank creates the money for your loan, it creates the principal — the $240,000. But you don't pay back $240,000. At six percent over thirty years, you pay back closer to $518,000. So who created the money to pay the interest?

The bank conjured the principal out of your signature. But it never created the interest. That money doesn't exist yet. So where does it come from?

Loans create money. Repaying destroys it.

Start with the part almost no one is taught: money in this system is created when someone borrows, and it is destroyed when they repay. The whole money supply is just the running sum of everyone's outstanding debt.

"Whenever a bank makes a loan, it simultaneously creates a matching deposit in the borrower's bank account, thereby creating new money."— Bank of England, "Money creation in the modern economy," 2014

Now put the two facts together. The interest on your loan was never created. The only place it can come from is someone else's new loan — fresh money, borrowed into existence somewhere else in the economy, so that the dollars exist for you to pay your interest with. Which means the total pile of debt can never shrink for long. It has to keep growing just to service itself.

The bicycle that can't stop pedaling

This system is a bicycle. It stays upright only while it's moving. Stop the borrowing — let the loans get paid off faster than new ones are written — and money gets destroyed faster than it's created, the supply contracts, and the whole thing falls over. That's not a recession; that's the machine's design showing through. So it must expand. Forever.

• More debt, every year, on purpose.
• More dollars chasing the same goods.
• Your saved dollars, quietly worth less.

That last line is inflation. It isn't an accident or a policy failure — it's the sound of the bicycle staying upright. The "two percent target" they announce so calmly is the most expensive lie you'll ever be told politely: the dollar losing value isn't a bug they're fighting, it's the system running exactly as built.

Watch the full breakdown

The trap — and the one way out of it

Here's the part that took me longest to accept. There is no exit inside the system. Dollars, bonds, money-market funds, savings accounts — every one of them is denominated in the very thing being expanded. Hiding in cash from inflation is hiding from the rain under a waterfall.

The exit has to be something that needs no expansion to survive — something with no interest to service, no new borrowers required, no one who benefits from making more of it. That's the whole case for Bitcoin, and it's a modest one, not a moonshot: twenty-one million, ever, a supply that doesn't have to grow to keep standing up. It is the one asset in this story that isn't riding the bicycle.

This is Episode 3 of The Money Machine, From The Inside — a series on how banks manufacture money from debt, why it drains every saver, and where the truth actually leads.
