Most of us grew up believing a tidy story about how banks work.
You deposit money → the bank keeps 10% → they lend the rest → the lending multiplies across the system.
It’s the “fractional reserve” idea -- a 10% reserve requirement that supposedly creates a 10× money multiplier.
It feels logical.
It feels stabilizing.
It feels like someone, somewhere, is keeping score.
But none of it is actually how money gets created.
And once you see the real mechanism, the entire system looks different.
THE STORY WE WERE TAUGHT
Textbooks teach:
Banks lend out deposits
Banks are constrained by reserves
Banks can only “multiply” money up to a limit
The limit comes from the equation 1 / 0.10 = 10, the so-called “money multiplier”
Ten dollars of loans for every dollar of deposits.
Clean. Orderly. Comfortable.
Too bad it’s fiction.
THE ACTUAL SEQUENCE
Here’s the part nearly nobody learns:
Banks do not lend out deposits.
Banks do not wait for deposits.
Banks do not multiply money from a reserve base.
Instead:
You ask for a loan
The bank approves it
They create a matching deposit in your name by typing it into their system
That deposit is the new money
Only afterward do they obtain reserves -- and the system supplies them as needed
In other words:
The loan creates the deposit.
Not the other way around.
Once you understand that single flip, everything changes.
WHY THIS BREAKS THE OLD STORY
If loans create deposits, then:
Deposits do not fund lending
Reserve requirements do not constrain lending
The traditional money multiplier collapses
The fractional reserve model assumes the constraint comes first.
But in reality, the constraint comes last, and it never limits lending.
Which means the “fractional reserve” model is not fractional at all.
It’s record-keeping that happens after the fact.
THE MYTH OF 1/.10 = 10
If banks aren’t limited by deposits,
and aren’t limited by reserves,
and money is created at the moment of lending,
then the formula 1/.10 = 10 is not a multiplier.
It’s a relic.
A teaching tool for a system that no longer exists.
Modern banking has no meaningful reserve constraint.
So the true description isn’t ten-to-one.
It’s infinity over zero.
That’s IOZ ™: unlimited credit creation on zero reserve constraint.
THE IOZ FORMULA – THE ONE THAT MATCHES REALITY
Fractional reserve banking assumes deposits fund loans and reserves constrain lending.
But because loans create deposits -- not the other way around -- the reserve requirement becomes irrelevant and fiat creation becomes unbounded.
So the textbook multiplier 1/.10 = 10 is a myth.
The real multiplier of modern banking is ∞/0: unlimited credit creation on zero restraint.
That is the modern system -- in one glance.
WHY THIS MATTERS
Once you see IOZ, several things snap into focus:
Inflation isn’t an accident -- it’s embedded in the structure
Credit growth must outrun the economy or the system stalls
Crises require liquidity injections because nothing holds the system up
Debt is the engine, not the byproduct
“Money” is not something the system has -- it is something the system creates on demand
IOZ isn’t a slogan.
It is the mathematical description of how banking actually works.
THE PUNCHLINE
The system we thought we had was 10-to-1.
The system we actually have is ∞/0.
Once you understand that, everything from inflation to debt to asset bubbles to gold to risk becomes clearer.
Infinity Over Zero isn’t philosophy.
It’s the operating system.
