Debt-based money creation is the most astonishing and least discussed truth about modern finance — every bank loan literally creates new money out of thin air, and when that loan is repaid, the money is destroyed. This article explains how it works step by step, why the interest problem creates a perpetual 'debt treadmill,' the Cantillon Effect, moral hazard, and what it means for Bangladesh's economy.
Imagine you wake up in the morning and buy a cup of tea. The shopkeeper takes 10 taka from you. That evening, he deposits it at the bank. The bank lends it to someone else. So far, so normal.
But here's a question that changes everything: where did that 10 taka actually come from?
Did Bangladesh Bank print it? Maybe. But according to Bangladesh Bank's data, total M2 (broad money) in Bangladesh in 2023 was approximately 17 lakh crore taka. The amount of physical notes printed by Bangladesh Bank? A tiny fraction of that.
The uncomfortable answer is this: most of the money in circulation wasn't printed by any government. Banks created it. Through lending. By making computer entries.
This is Debt-Based Money Creation — and it's the biggest, least-discussed truth about how modern money actually works.
In simple terms: every time a bank issues a loan, new money comes into existence. And when that loan is repaid, that money ceases to exist.
Money is created through lending, not through printing. That's Debt-Based Money Creation.
The Bank of England confirmed this in their 2014 Quarterly Bulletin: "Commercial banks create money in the form of bank deposits, by making new loans. Whenever a bank makes a loan, it simultaneously creates a matching deposit in the borrower's bank account, thereby creating new money."
That single statement overturns the entire textbook model of how banking works.
You want to buy a house. The price is 50 lakh taka. You don't have the money. You go to the bank for a home loan.
The bank checks your income, credit history, and collateral. The loan is approved. Now, what does the bank do? Does it pull 50 lakh taka from its vault? No. Does it take it from someone else's savings? No.
The bank makes two entries in its accounting system:
Asset side: 50 lakh taka receivable from you (Loan Asset)
Liability side: 50 lakh taka credited to your account (Deposit Liability)
At this exact moment, 50 lakh taka of brand new money comes into existence. It didn't exist before. Now it does. Created entirely through a computer entry.
You use that 50 lakh to pay the house seller. The seller deposits it in their bank. That bank lends a portion of it to someone else. And so one loan's newly created money ripples through the entire economy.
Each month you make a payment. The principal portion of your installment, as it returns to the bank, destroys money. Just as money was born when the loan was created, it dies when the loan is repaid.
The interest portion becomes the bank's income. It doesn't create new money. It comes from money already circulating in the economy. And this is where the system's deepest problem begins.
Now that we understand the concept, let's look at the actual numbers — how much money can be created, and what rules govern it.
The bedrock of modern banking is a simple rule: banks don't have to hold onto every dollar you deposit. They keep a fraction in reserve and lend out the rest. This is called Fractional Reserve Banking.
Let's say the reserve requirement is 10%. You deposit $1,000.
Step 1: Bank A receives $1,000 → Keeps $100 in reserve → Lends out $900
Step 2: Bank B receives $900 → Keeps $90 → Lends out $810
Step 3: Bank C receives $810 → Keeps $81 → Lends out $729
Step 4: Bank D receives $729 → Keeps $73 → Lends out $656
The chain continues until your original $1,000 deposit has created a total of $10,000 in the economy. This is the Money Multiplier in action.
Formula: Money Multiplier = 1 ÷ Reserve Ratio = 1 ÷ 0.10 = 10
Total money created = Initial Deposit × Money Multiplier = $1,000 × 10 = $10,000
The lower the reserve ratio, the higher the multiplier:
20% reserve → 5× multiplier → $5,000 total
10% reserve → 10× multiplier → $10,000 total
5% reserve → 20× multiplier → $20,000 total
2% reserve → 50× multiplier → $50,000 total
In Bangladesh, Bangladesh Bank imposes two reserve requirements. The CRR (Cash Reserve Ratio) is currently 4% — banks must hold 4% of deposits as cash with the central bank. The SLR (Statutory Liquidity Ratio) is 13% — another 13% must be held in government securities or cash. Combined, the effective reserve is about 17%, giving Bangladesh a theoretical Money Multiplier of approximately 5.9×.
Fractional Reserve is an older concept. In modern banking regulation, what matters even more is CAR — the Capital Adequacy Ratio. Internationally, this is set by the Basel Committee, and in Bangladesh, it's enforced by Bangladesh Bank.
Formula: CAR = (Tier 1 Capital + Tier 2 Capital) ÷ Risk-Weighted Assets × 100
Example: A bank has total capital of BDT 100 crore and risk-weighted assets of BDT 800 crore. CAR = 100 ÷ 800 × 100 = 12.5%.
Under Basel III, the minimum CAR is 10.5%. Bangladesh Bank requires 12.5%.
What Are Risk Weights?
Not all loans carry the same risk, so different types of assets are assigned different weights:
Government treasury bills: 0% risk weight → BDT 100 crore in loans = 0 RWA
Home loans (with mortgage): 50% → BDT 50 crore RWA
SME loans: 75% → BDT 75 crore RWA
Corporate loans: 100% → BDT 100 crore RWA
Unsecured consumer loans: 150% → BDT 150 crore RWA
A 150% risk weight on consumer loans means — the more of these a bank issues, the higher its RWA climbs, the lower its CAR falls, and the more capital it must hold. Risky lending literally shrinks a bank's capacity to lend more.
Many people assume these are the same thing with different names. They're not. They answer two completely different questions.
Fractional Reserve asks: Can the bank give depositors their money if they show up tomorrow? It targets liquidity risk — the everyday door.
CAR asks: Can the bank survive if a chunk of its loans go bad? It targets solvency risk — the storm.
Think of it this way — Fractional Reserve says "Keep the daily door running smoothly," while CAR says "Make sure you can still stand after a hurricane."
In Bangladesh, this is a serious issue. Many state-owned banks have repeatedly fallen below the minimum CAR threshold. When non-performing loans rise, RWA increases, CAR drops, and lending capacity shrinks. To break this vicious cycle, the government has repeatedly recapitalized state-owned banks — meaning taxpayer money fills the gap left by bad loans.
This is the single biggest misconception about modern banking. And it's not just ordinary people who got it wrong — economics textbooks taught it incorrectly for decades.
Most economics textbooks present banks as intermediaries. The story goes like this: people save money and deposit it, the bank lends those deposits to borrowers, borrowers spend the money, and it eventually returns to the bank. In this model, deposits come first, loans come second. The bank creates nothing — it simply passes savings from one person to another.
This sounds logical. But it's wrong.
The Bank of England stated directly in its 2014 Quarterly Bulletin ("Money Creation in the Modern Economy"): "Commercial banks create money in the form of bank deposits by making new loans. Whenever a bank makes a loan, it simultaneously creates a matching deposit in the borrower's account, thereby creating new money."
Here's how it actually works. Karim applies for a BDT 50 lakh home loan. There's no pre-existing deposit, no old money sitting around. The bank approves the loan. At that moment, two entries appear in the bank's accounting system:
Asset side: BDT 50 lakh receivable from Karim [Loan Asset]
Liability side: BDT 50 lakh credited to Karim's account [Deposit Liability]
No money left the vault. No other depositor's money was moved. Two numbers were simply added to a computer — and at that instant, BDT 50 lakh of brand-new money came into existence. Karim pays the house seller. The seller deposits it in their bank. Now that bank has a new deposit. The sequence is clear: loans first, deposits second. The exact opposite of what textbooks taught.
Textbook Model: Sequence → Deposits → Loans | Bank = Intermediary | New money comes from savers' pockets
Reality Model: Sequence → Loans → Deposits | Bank = Money Creator | New money comes from nothing — a computer entry
In the textbook model, repaid loans return money to the bank for re-lending. But in reality, the reverse process occurs.
When Karim pays his monthly installment, the principal portion triggers two entries:
Asset side: Receivable from Karim decreases by BDT 50,000
Liability side: Karim's account balance decreases by BDT 50,000
Both numbers decrease simultaneously. That amount of money is erased from the system. Born in a computer entry, died in a computer entry.
This is why when lending slows down, the total amount of money in the economy shrinks. This is exactly what happened during the 2008 financial crisis — banks stopped issuing new loans while old loans were being repaid, causing the money supply to contract rapidly. Governments responded with Quantitative Easing to pump new money into the gap.
If banks can create money from thin air, what stops them from lending infinitely? Three constraints:
First, CAR — more loans mean more risk-weighted assets, which require more capital. When capital runs out, lending stops.
Second, Liquidity — after a loan is made, the money may flow to another bank. The originating bank then needs to borrow reserves from the central bank, which costs money.
Third, Loan Demand — banks can't lend if nobody wants to borrow, and borrowers must demonstrate the ability to repay.
In other words, banks can't create unlimited money — but the limit isn't determined by the size of their vault. It's determined by capital, liquidity, and demand.
This is the most profound and least understood truth about the system.
When a bank issues a loan, it creates the principal. But it does NOT create the interest.
Think about it. You borrowed 50 lakh taka. The bank created 50 lakh in new money. But over 20 years, you'll repay 85 lakh taka — 50 lakh principal plus 35 lakh in interest. Where does the 35 lakh for interest come from? The bank never created it.
It comes from money already flowing through the economy. Someone's salary, someone's business income, someone's savings.
What does this mean? The total debt in the system always exceeds the total money supply. Because the bank creates principal but never creates the interest it demands back.
Let's make this crystal clear with a simple thought experiment:
Imagine there are only 10 people on Earth and one bank. The bank lends each person 100 taka — total money created: 1,000 taka. But with interest, each person owes 150 taka — total debt: 1,500 taka. There's only 1,000 taka in the system. Where does the other 500 come from?
It doesn't. So not everyone can repay. Someone WILL default. This is a mathematical certainty built into the system.
The only solution? Constant new lending. New loans create new money. New money pays old interest. But new loans bring new interest. So even more new loans are needed.
This is the 'debt treadmill.' Once you step on, there's no stepping off.
This truth was never exactly secret. It's been acknowledged at various points in history.
"It is well enough that people of the nation do not understand our banking and monetary system, for if they did, I believe there would be a revolution before tomorrow morning." — Henry Ford, 1941
In 1969, the Federal Reserve Bank of Boston published a document stating: "When banks make loans, they create new bank money."
But the most significant admission came in 2014, when the Bank of England stated plainly in their Quarterly Bulletin that banks create deposits through lending — not the other way around. This single publication challenged the entire textbook model that had been taught for decades.
According to the Bank for International Settlements (BIS), in advanced economies, only 3-5% of total money exists as physical notes and coins. The remaining 95-97% is digital entries — created by commercial bank lending.
Research by the UK's Positive Money organization found that in Britain, just 3% of money is central bank-issued notes, while 97% is bank-created.
In Bangladesh, reserve money (base money) in 2023 was about 3.8 lakh crore taka, while broad money (M2) was approximately 17 lakh crore taka. The difference — roughly 13 lakh crore taka — was essentially created by commercial banks through lending.
When new money is created, everyone doesn't receive it simultaneously. This inequality is called the Cantillon Effect.
Eighteenth-century economist Richard Cantillon first identified this: those who receive new money first can buy assets at pre-inflation prices. By the time the money trickles down to ordinary people, prices have already risen.
In modern economics, here's how it plays out:
Central banks do Quantitative Easing or governments issue stimulus. That new money first reaches large banks and financial institutions. They buy stocks, real estate, and assets. Prices rise. Months later, ordinary people receive some benefit through salary increases or government aid — but by then, housing costs, food prices, and essentials have already jumped.
After 2008, the Federal Reserve conducted approximately $4 trillion in Quantitative Easing. During this period, the S&P 500 rose by roughly 400%. Meanwhile, the median American household income grew by just 15%. The wealth gap widened dramatically — and the Cantillon Effect was the mechanism.
Debt-based money creation creates a dangerous incentive structure.
Banks know that if they fail, the government will bail them out. Because if a large bank collapses, the entire system crumbles and millions lose their savings. So the government has no choice. In banking, this is called "Too Big to Fail."
Knowing this, banks take excessive risks. Higher risk means higher interest, higher profits. If it works out, the bank keeps the profits. If it doesn't, taxpayers foot the bill.
In 2008, the U.S. government's TARP bailout package was approximately $700 billion — funded by American taxpayers. The bank executives who created the crisis? Many kept their bonuses and jobs.
Bangladesh operates within the debt-based money creation system, but with specific problems that make the system even more fragile.
Bangladesh Bank data shows NPLs reached approximately 1.55 lakh crore taka by the end of 2023. Experts believe the real number is higher due to loan restructuring that keeps bad loans off the official books. Non-performing loans mean the bank created money but it's not coming back — eroding capital, reducing CAR, and shrinking lending capacity across the entire economy.
Bangladesh's moral hazard problem is acute. State-owned banks know the government will always rescue them. This leads to politically motivated lending to unqualified borrowers. Between 2014 and 2022, the government injected over 28,000 crore taka into state-owned banks through recapitalization.
According to the Bangladesh Bureau of Statistics, inflation exceeded 9% in 2023. Bank-created money through lending, combined with government deficit financing, has been a major driver. The Cantillon Effect means asset owners benefit while wage earners suffer the most from rising prices.
First, modern economic growth would be impossible without this system. Without credit-based money creation, entrepreneurs couldn't start businesses, factories wouldn't be built, and jobs wouldn't exist.
Second, the system allows today's investment against tomorrow's productivity. A factory built on borrowed money generates revenue that repays the loan — creating real value for society.
Third, central bank interest rate controls can stabilize the system.
First, banks create money from nothing through a computer entry and then charge interest on it. This raises a fundamental moral question: why should this power belong exclusively to private banks?
Second, the interest-principal problem means the system has a permanent mathematical deficit. Growth must never stop, or the system collapses.
Third, new money flows disproportionately to the wealthy, widening inequality.
Fourth, the Too Big to Fail problem means banks privatize profits and socialize losses.
Islamic economics rejects this system at its core. Interest (riba) is prohibited. Creating money from nothing and charging interest on it is fundamentally unacceptable. The alternative — Musharaka (partnership-based) models — requires genuine risk-sharing, which fundamentally changes the incentive structure.
Only the central bank would create money. Commercial banks would lend but couldn't create new money. Switzerland held a referendum on this in 2018 — 74% voted against it, fearing economic rigidity.
Many central banks are exploring digital currencies. Bangladesh Bank is researching 'Digital Taka.' A CBDC could allow the central bank to send digital money directly to citizens' wallets — potentially bypassing the commercial banking system for money creation.
Bitcoin's maximum supply is fixed at 21 million coins — no bank can multiply it. But extreme volatility means it's not yet ready to replace traditional currency.
Stop and think for a moment.
Your entire life, you assumed money was something tangible — backed by gold, reserves, or at least physically printed by the government. But in reality, the money you used to buy tea this morning probably originated from someone's bank loan — created by a computer entry, backed by nothing more than a promise to repay.
This system survives because everyone believes it works. If everyone simultaneously lost faith — if everyone rushed to the bank at once — the system would collapse. Because the money isn't actually there.
This is the world's largest collective act of faith. 8 billion people believing simultaneously is what makes it work.
"The process by which banks create money is so simple that the mind is repelled." — John Kenneth Galbraith, Money: Whence It Came, Where It Went, 1975
And perhaps that's the biggest truth of all — we depend on an incredibly complex system whose foundation is nothing more than belief. Just belief.
Debt-based money creation isn't just an economic technique. It's one of the most consequential inventions of modern civilization — one that has enabled unimaginable growth on one hand, while creating a trap that's extraordinarily difficult to escape on the other.
Loans create money. Money drives the economy. The economy drives life. But stop lending, and money dies. Money dies, and the economy breaks.
Understanding this matters especially in Bangladesh. Our high non-performing loans, fragile banking system, and persistent inflation aren't isolated events. They're all symptoms of this single system.
And as ordinary people, we need to know this — because we receive the least benefit from this system, yet bear the greatest risk when it fails.
A ‘SWOT’ analysis is essentially a planning process that helps an organization identify new directions it can pursue while overcoming its challenges. The acronym ‘SWOT’ stands for Strengths, Weaknesses, Opportunities, and Threats. Therefore, a SWOT analysis is an excellent strategy for evaluating these four aspects of any organization.
