When you deposit €1,000 at the bank, you think it's sitting in a vault. In reality, the bank just created up to €10,000 from your deposit. Welcome to the world of fractional reserve.

Introduction: The Vault Myth

Close your eyes and imagine your bank. You probably see a large building with a reinforced vault in the basement, filled with banknotes and gold bars waiting patiently for your return.

This image is completely false.

Your money is not "stored" at the bank. It doesn't even exist in a physical sense. What you see on your bank statement is a number in a computer – a promise from the bank to give you that money if you ask for it.

And here's the secret that few people know: banks create money every time they grant a loan. Not with other customers' savings. Out of nothing.

The Myth of Banking Intermediation

What We're Taught

In classical economics textbooks, we're told that banks are financial intermediaries:

1. Savers deposit their money at the bank
2. The bank lends this money to borrowers
3. The bank earns money from the interest rate difference (interest margin)

This model suggests that the bank can only lend money it already has.

The Reality: Banks Create Money

In 2014, the Bank of England published a revolutionary document that explicitly contradicted the classical model:

"Commercial banks create money, in the form of bank deposits, whenever they make a new loan. [...] This differs from the description found in many economics textbooks."

— Bank of England Quarterly Bulletin, Q1 2014

The Bundesbank (German central bank) confirmed:

"It's not bank deposits that allow banks to make loans. It's the opposite: loans create deposits."

— Bundesbank Monthly Report, April 2017

The ECB as well:

"Banks can create scriptural money on their own initiative."

— ECB, official documentation

This is not a conspiracy theory. It's the official explanation from the central banks themselves.

The Fractional Reserve System

The Principle

The fractional reserve banking system allows banks to keep only a fraction of deposits in reserve and lend out the rest.

Historically:

• 10% required reserve (USA before 2020)
• 1% required reserve (Eurozone before 2012)
• 0% required reserve (Eurozone since 2012, USA since 2020)

You read that correctly: today, in the Eurozone and the United States, banks have no reserve requirement on deposits.

The Multiplier Effect

Even with required reserves, the multiplier effect was impressive.

Example with 10% reserve:

Result: €1,000 of initial deposit allows the creation of up to €10,000 of money (multiplier = 1/reserve ratio).

With a reserve ratio of 0% (current situation), the theoretical multiplier is... infinite.

The Money Creation Process

Step by Step

Let's follow the journey of a €200,000 mortgage:

Step 1: You apply for a loan You visit your banker to buy an apartment. You request €200,000.

Step 2: The bank checks your creditworthiness It verifies your income, debt ratio, and credit history.

Step 3: The bank "creates" the money If the loan is approved, the bank makes two simultaneous accounting entries:

• On the asset side: €200,000 claim on you (you owe this money)
• On the liability side: €200,000 deposit in your account (you have this money)

There. The money now exists. It didn't exist before. The bank didn't take it from anywhere. It created it through an accounting entry.

Step 4: You spend the money You transfer the €200,000 to the apartment seller.

Step 5: The money circulates in the economy The seller deposits the money in their bank. Their bank can now create new loans based on this deposit.

Step 6: You repay for 25 years Each month, you repay principal + interest.

Step 7: The money is "destroyed" When you repay the principal, the bank cancels both entries. The money disappears.

But the interest? The interest you pay was never created. It must come from elsewhere in the economy.

Simplified Diagram

BEFORE THE LOAN:
┌─────────────────────────────────┐
│         BANK ABC                │
├─────────────────────────────────┤
│ Assets          │ Liabilities   │
├─────────────────┼───────────────┤
│ Reserves: €100  │ Deposits: €100│
│                 │               │
└─────────────────┴───────────────┘

AFTER THE €200,000 LOAN:
┌─────────────────────────────────┐
│         BANK ABC                │
├─────────────────────────────────┤
│ Assets          │ Liabilities   │
├─────────────────┼───────────────┤
│ Reserves: €100  │ Deposits: €100│
│ Loan: €200,000  │ New deposit:  │
│                 │ €200k         │
└─────────────────┴───────────────┘

Assets and liabilities increased by €200,000.
Both sides balance perfectly.
But €200,000 of new money now exists.

Interest: The Hole in the System

The Mathematical Problem

Here is the central paradox of the system:

1. Banks create the principal of loans (e.g., €200,000)
2. Banks do not create the interest (e.g., €100,000 over 25 years)
3. But borrowers must repay principal + interest (€300,000)

Where do the €100,000 in interest come from?

Answer: From the existing money supply. That is, from money that other borrowers have created through their own loans.

The Debt Spiral

This system creates a structural dependence on growing debt:

1. To pay today's interest, new loans are needed
2. These new loans generate new interest
3. Even more loans are needed to pay this interest
4. And so on...

Mathematical consequence: Total debt must grow exponentially for the system to function.

Debt grows faster than GDP. This is structurally inevitable in a system based on credit-based money creation.

Who Benefits From This System?

Banks

Banks receive interest on money they created for free.

Simple calculation:

• The bank creates €200,000 through an accounting entry (cost: ~€0)
• You repay €300,000 over 25 years
• Bank profit: €100,000

It's as if a counterfeiter could legally print bills and lend them to you with interest.

First Borrowers

The Cantillon Effect (named after economist Richard Cantillon, 1730):

Newly created money doesn't spread uniformly through the economy. The first to receive it (borrowers, financed companies) can buy assets before prices rise.

Typical order:

1. Banks create the money
2. Large companies/investors borrow it first
3. Money gradually circulates
4. Prices rise
5. Workers receive the raise last

Result: The rich get richer, workers see their purchasing power decline.

Governments

Governments can borrow well beyond their fiscal means:

• Issue bonds bought by banks
• Banks create money to buy these bonds
• Government spends this money
• Inflation reduces the real value of the debt

It's a disguised tax that requires no vote.

Who Loses?

Savers

If you keep your money in a savings account at 3%:

• Real inflation: 4-5%
• Net return: -1 to -2% per year

Your savings silently melt away.

Workers

Wages always lag behind inflation:

• New money causes prices to rise
• Your employer raises salaries... with a delay
• In the meantime, your purchasing power drops

Retirees

Pensions often poorly indexed to real inflation. Retirees' purchasing power structurally decreases.

Future Generations

Growing debt will be their burden. They'll have to repay (or suffer the system's collapse).

Differences Between Europe and USA

Fractional Reserve Today

Money Creation

Both zones operate on the same principle:

• Commercial banks create most of the money
• Central banks create "reserves" and influence rates
• No limit based on real assets

Quantitative Easing

Since 2008, central banks have added QE (Quantitative Easing):

• The ECB/Fed buys bonds
• It pays with created money
• Bank reserves increase
• Theoretically, this stimulates credit

Fed balance sheet: $900B (2008) → $8,900B (2022) ECB balance sheet: €2,000B (2008) → €8,800B (2022)

Why Does This System Still Hold?

Collective Trust

The system works as long as people believe it works.

If everyone withdrew their money from banks tomorrow, the system would instantly collapse. Banks don't have that money.

That's why governments guarantee deposits (€100,000 in Europe). This guarantee maintains trust.

No Visible Alternative (Until Recently)

For a long time, there was no credible alternative:

• Gold isn't practical for daily transactions
• Local currencies remain marginal
• Physical cash is declining

Aligned Interests

Banks, governments, and large corporations all benefit from the system:

• Banks: profits from money creation
• Governments: unlimited financing
• Large corporations: access to cheap credit

Who would want to change a system that enriches them?

Deliberate Complexity

The system is complex enough to discourage understanding.

Technical terms (M0, M1, M2, M3, money multiplier, open market operations...) create a veil of expertise that intimidates ordinary citizens.

Bitcoin: The Anti-Fractional Reserve

Fixed and Verifiable Supply

Bitcoin operates on diametrically opposite principles:

Full Reserve By Default

When you own 1 bitcoin, that bitcoin actually exists on the blockchain. It's not a promise of payment. It's not someone else's debt.

No one can create new bitcoins by granting a loan. The supply follows a predefined and immutable schedule.

No Systemic Debt

In the Bitcoin ecosystem:

• You can lend your bitcoins (DeFi platforms)
• But this doesn't create new bitcoins
• The total in circulation remains the same

No money creation = no mandatory debt spiral.

FAQ

Are my deposits safe at the bank?

Your deposits are guaranteed by the Deposit Guarantee Fund up to €100,000 per person per institution in France/Europe. Beyond that, or in case of a major systemic crisis, risk exists. In 2013, Cyprus levied deposits above €100,000.

What happens in case of a bank run?

If all customers want to withdraw their money simultaneously, the bank fails because it doesn't have the funds. That's why governments guarantee deposits and central banks can inject "emergency" liquidity. But in a systemic crisis, these mechanisms may be insufficient.

Why don't economists criticize this system?

Many mainstream economists are trained in a paradigm that considers this system normal. Additionally, many economists work for banks or institutions that profit from the system. The Austrian School (Mises, Hayek, Rothbard) has been criticizing this system for a century but remains a minority.

Do stablecoins work the same way?

It depends. "Fractional" stablecoins (like the old UST from Terra) operated on a similar principle and collapsed. "Collateralized" stablecoins (USDC, USDT in theory) are supposed to have $1 of reserves for each token. But without transparent audits, it's difficult to verify.

What can I do to protect myself?

Diversify outside the banking system: real assets (real estate, physical gold), digital assets (Bitcoin in self-custody), quality stocks. Don't keep more than necessary in bank accounts. Understand that your "savings" in euros loses value every year.

Conclusion: The Reality Behind the Curtain

We live in a system where:

1. Money is created by commercial banks with each loan
2. There is no longer any reserve requirement in major economies
3. Interest is never created, forcing perpetual debt growth
4. Beneficiaries are banks and first borrowers
5. Losers are savers and workers

This is not a dysfunction of the system. It is the system itself.

Understanding this mechanism is essential for making informed financial decisions. The Bitcoin alternative exists precisely because Satoshi Nakamoto understood these mechanisms and wanted to offer an alternative.
