Banks: Where Money Gets Created
The Goldsmith's Secret
Let us go back to seventeenth-century London. The year is 1660 or thereabouts. England has just emerged from a civil war, a regicide, a republic, and a restoration. It is a turbulent time. And in the narrow lanes of the City of London, a quiet revolution is underway.
Goldsmiths — craftsmen who work with precious metals — have strong vaults. Wealthy Londoners, nervous about thieves, begin leaving their gold with the goldsmiths for safekeeping. The goldsmith gives a receipt: "I hold 100 pounds of gold on behalf of Mr. Thomas Hartley."
Mr. Hartley discovers something convenient. When he needs to pay a debt, he does not go back to the goldsmith, withdraw his gold, carry it across London, and hand it over. Instead, he simply gives the receipt to his creditor. The creditor accepts it — after all, it is backed by real gold in the vault.
The receipts begin circulating as money. This is the origin of the banknote.
But then the goldsmith notices something remarkable. On any given day, only a fraction of his depositors come to withdraw their gold. Most of the gold just sits in the vault. Day after day. Week after week.
And here, in this quiet observation, is one of the most consequential discoveries in economic history:
If most of the gold just sits there... the goldsmith can lend it out.
He begins lending gold to borrowers — charging interest, of course — while still issuing receipts to depositors. He is now issuing more receipts than he has gold to back them. He is, in effect, creating money.
As long as all the depositors do not come for their gold at the same time, the system works. The goldsmith earns interest on money that is not his. The borrowers get capital they need. The depositors believe their gold is safe.
Everyone is happy. Until they are not.
Look Around You
Walk into any bank in India — State Bank, HDFC, ICICI. Look at the tellers, the computers, the vault door at the back. You might think this building exists to store money. To keep your deposits safe.
It does that. But that is not its main business.
The main business of a bank is to create money. Every time a bank makes a loan, it creates new money that did not exist before. This is not a conspiracy theory. It is not controversial. It is stated plainly by the Bank of England, the Reserve Bank of India, and every central bank in the world.
And yet most people do not know it.
How Banks Actually Create Money
Let us walk through the process, step by careful step.
Step 1: You deposit money.
You take Rs. 10,000 to your bank and deposit it. The bank now has your 10,000 in its vault (or, more likely, as a digital record). Your account shows a balance of 10,000.
Step 2: The bank lends most of it out.
The bank is required to keep a fraction of your deposit as a "reserve" — in India, this is the Cash Reserve Ratio (CRR), which has historically been around 4-5%. Let us say 10% for simplicity.
So the bank keeps Rs. 1,000 as reserve and lends out Rs. 9,000 to someone else — say, a shopkeeper who needs a loan to buy inventory.
Step 3: Here is the magic.
Your bank account still shows Rs. 10,000. You have not lost anything. You can check your balance, and it is all there.
But the shopkeeper now also has Rs. 9,000. The bank created a new deposit in his account (or handed him a check he can deposit elsewhere).
The total money in the economy just increased from Rs. 10,000 to Rs. 19,000.
Your 10,000 still exists (in your account). And the shopkeeper's 9,000 also exists (in his account or his hand). The bank created 9,000 of new money by the act of lending.
Step 4: The process repeats.
The shopkeeper deposits his 9,000 in his bank. That bank keeps 10% (Rs. 900) and lends out Rs. 8,100 to someone else. Now the total money is 10,000 + 9,000 + 8,100 = 27,100.
And so on.
The Money Multiplier
This process can be expressed as a simple formula:
Total money created = Initial deposit / Reserve ratio
If the reserve ratio is 10%:
Total money = 10,000 / 0.10 = Rs. 100,000
Your single deposit of Rs. 10,000 can ultimately create up to Rs. 100,000 in the banking system. The multiplier is 1 / reserve ratio = 10.
THE MONEY CREATION CHAIN
Your deposit: Rs. 10,000
Reserve ratio: 10%
Round | Deposit | Reserve | Loan
-------|----------|---------|--------
1 | 10,000 | 1,000 | 9,000
2 | 9,000 | 900 | 8,100
3 | 8,100 | 810 | 7,290
4 | 7,290 | 729 | 6,561
5 | 6,561 | 656 | 5,905
6 | 5,905 | 590 | 5,315
7 | 5,315 | 531 | 4,784
... | ... | ... | ...
TOTAL |100,000 | 10,000 | 90,000
From Rs. 10,000 in physical cash,
the banking system creates Rs. 100,000
in total deposits.
Rs. 90,000 was created out of thin air
by the act of lending.
Read that again. Rs. 90,000 — nine-tenths of the total money supply in this example — was created by banks. Not by the government printing press. Not by the central bank. By ordinary commercial banks, through the mundane act of making loans.
This is called fractional reserve banking. The bank holds a fraction of deposits as reserves and lends the rest. It is the foundation of the modern banking system.
"The process by which banks create money is so simple that the mind is repelled. When something so important is involved, a deeper mystery seems only decent." — John Kenneth Galbraith
Wait — Is This Real?
If you are feeling uneasy, you should be. The idea that banks create money from nothing is counterintuitive. It feels like a trick. Like alchemy.
It is not a trick. But it is alchemy of a kind — social alchemy. Here is why it works:
The money banks create is not physical. It is an entry in a ledger — a number in your account. When the bank gives the shopkeeper a loan of Rs. 9,000, it does not print new notes. It types a number into a computer. The shopkeeper's account now shows 9,000, and the bank's books show a loan of 9,000. New money has been created as a pair of accounting entries: a deposit (asset to the depositor, liability to the bank) and a loan (asset to the bank, liability to the borrower).
The money is backed by a promise. The shopkeeper has promised to repay the loan with interest. His promise to pay is the "backing" for the new money. If he repays, the money is destroyed (yes — repaying a loan destroys money, just as making a loan creates it). If he defaults, the bank takes a loss.
The system works as long as confidence holds. As long as depositors believe their money is safe, they do not all withdraw at once. As long as borrowers repay their loans, the money supply remains stable.
But when confidence breaks, the system can collapse spectacularly. And that brings us to bank runs.
When Everyone Wants Their Money Back
Remember the goldsmith? His system worked as long as all depositors did not come at once. The modern banking system has the same vulnerability.
A bank run happens when depositors lose confidence and all try to withdraw their money simultaneously. Since the bank has lent most of the money out, it cannot pay everyone. The bank fails. Depositors lose their savings. Panic spreads to other banks. The whole system can collapse like dominoes.
Bank runs are terrifying because they are self-fulfilling. A bank might be perfectly healthy — its loans might be sound, its management might be competent. But if enough people believe the bank is in trouble and rush to withdraw, the bank will indeed fail. The fear creates the reality it fears.
Some of the worst moments in economic history were bank runs:
The Great Depression (1930-33): Over 9,000 American banks failed. Millions of families lost their life savings. The bank failures turned a recession into a catastrophe.
Northern Rock (2007): The first bank run in Britain in 150 years. Long queues formed outside branches as depositors scrambled to withdraw. It was one of the early signals of the global financial crisis.
Yes Bank (2020): In India, Yes Bank faced a crisis when the RBI imposed a moratorium, limiting withdrawals to Rs. 50,000 per account. Depositors panicked. The government eventually orchestrated a rescue.
What Actually Happened
The most famous bank run in Indian history occurred during the collapse of the Bank of Karad in 1992, but the pattern is ancient. In 1866, the failure of Overend, Gurney & Company in London — then the world's largest discount house — caused a panic so severe that crowds blocked the streets around the Bank of England.
The Bank of England's response set the template that central banks follow to this day: it lent freely to solvent banks, acting as "lender of last resort." This phrase, coined by Walter Bagehot in his 1873 book Lombard Street, became the first principle of central banking:
"Lend freely, at a high rate, against good collateral."
When the RBI intervened in Yes Bank's crisis in 2020, it was following the same principle, 150 years later.
Deposit Insurance: The Safety Net
After the catastrophe of the Great Depression, the United States created the Federal Deposit Insurance Corporation (FDIC) in 1933. Its purpose: to guarantee bank deposits up to a certain amount, so that ordinary savers would never again lose their money to a bank failure.
India has a similar system. The Deposit Insurance and Credit Guarantee Corporation (DICGC), a subsidiary of the RBI, insures bank deposits up to Rs. 5 lakh (Rs. 500,000) per depositor per bank.
Deposit insurance is a brilliant solution to the bank run problem. If you know your deposits are guaranteed by the government, you have no reason to panic. Even if others withdraw, your money is safe. And if no one panics, the bank does not fail.
It is a case where confidence creates the stability it relies on — the mirror image of a bank run, where fear creates the failure it fears.
But deposit insurance also creates a problem: moral hazard. If depositors know their money is safe no matter what, they have less incentive to choose their bank carefully. And if banks know that depositors will not flee, they have more incentive to take risks with depositors' money.
This tension — between stability and risk-taking — runs through the entire history of banking regulation.
The Medici Bank: Where Modern Banking Began
Let us step back in time to understand where this system came from.
Florence, Italy, the fifteenth century. The Renaissance is in full bloom. And at the center of Florentine power sits the Medici family, whose wealth is built not on land or armies but on banking.
The Medici Bank, founded by Giovanni di Bicci de' Medici in 1397, was the largest and most respected bank in Europe for nearly a century. It served popes, kings, and merchants across the continent.
The Medici Bank pioneered several innovations that define banking to this day:
Branch banking — the Medici operated branches across Europe: Rome, Venice, Avignon, Bruges, London. Each branch had a local manager but reported to the head office in Florence. This is the model every multinational bank still follows.
Double-entry bookkeeping — while not invented by the Medici, they were among its early adopters. This system of recording every transaction as both a debit and a credit made it possible to track complex financial operations with precision. It is the foundation of all modern accounting.
Letters of credit — instead of physically transporting gold across bandit-infested roads, a merchant could deposit money at the Medici branch in Florence and receive a letter authorizing him to withdraw the equivalent at the branch in Bruges. Money moved as paper. Brilliantly simple.
Foreign exchange — the Medici traded in multiple currencies, profiting from the differences. They also disguised interest charges as exchange rate fees, since the Church banned usury (lending at interest).
The Medici Bank eventually failed — overextended by bad loans to unreliable kings. But the model it created survived and flourished.
"Banking was conceived in iniquity and was born in sin. The bankers own the earth." — Josiah Stamp, Director of the Bank of England, 1920s
The Bank of England: The First Central Bank
In 1694, England was at war with France and desperately needed money. A Scottish merchant named William Paterson proposed a solution: a group of wealthy investors would lend the government 1.2 million pounds. In return, they would receive a royal charter to operate a bank — the Bank of England.
This was the birth of the modern central bank — though it would take centuries for the Bank of England to become what we now understand as a central bank.
The key innovation: the government got money, and the investors got the right to create money. The Bank of England could issue banknotes — paper money backed by the government's promise to repay its debt. These notes circulated as currency.
The Bank of England was, from birth, intertwined with government debt. And this relationship — between governments and the banks that fund them — remains the central dynamic of monetary systems worldwide.
The Indian Story: From Hundis to UPI
India's banking history is as old as any in the world.
Hundis — informal bills of exchange — were used in India for centuries. A merchant in Surat could send a hundi to a merchant in Agra, instructing him to pay a certain amount to a specified person. Hundis circulated across the subcontinent, facilitating trade without the physical movement of gold or silver. The hundi system was sophisticated, with different types for different purposes: darshani (payable on sight), muddati (payable after a specified period), and others.
Shroffs and sahukars — moneylenders and bankers — were central figures in Indian commercial life for millennia. The Jain and Marwari trading communities developed banking practices that, in many ways, paralleled European developments independently.
The colonial period brought European-style banking to India. The Bank of Hindostan (1770), the Bank of Bengal (1806), the Bank of Bombay (1840), and the Bank of Madras (1843) were established under British rule. The three Presidency Banks eventually merged to form the Imperial Bank of India in 1921, which became the State Bank of India in 1955.
Bank nationalization (1969): In one of the most dramatic economic decisions in Indian history, Prime Minister Indira Gandhi nationalized fourteen major commercial banks. The stated goal: to extend banking services to rural areas and to ensure that bank credit served the broader economy, not just industrial elites. The move was hugely popular and hugely controversial.
The results were mixed. Bank branches did spread across rural India — from about 8,000 in 1969 to over 60,000 by the 1990s. Millions of Indians opened bank accounts for the first time. But the nationalized banks also became bureaucratic, politically influenced, and burdened with bad loans.
The liberalization era (1991 onwards) opened the door to private banks — HDFC, ICICI, Axis, and others. These banks brought technology, efficiency, and customer service that the nationalized banks struggled to match.
UPI and the digital revolution: In 2016, the National Payments Corporation of India (NPCI) launched the Unified Payments Interface (UPI). This system allowed instant, free, mobile-to-mobile payments. By 2024, UPI was processing over 10 billion transactions per month. India went from a predominantly cash economy to one of the world's most advanced digital payment ecosystems in less than a decade.

TOTAL DEPOSITS IN THE SYSTEM:
Your deposit: Rs. 10,000
+ Created by Bank A: Rs. 9,000
+ Created by Bank B: Rs. 8,100
+ Created by Bank C: Rs. 7,290

================================
TOTAL: up to Rs. 100,000
ORIGINAL CASH: Rs. 10,000
MONEY CREATED BY BANKS: Rs. 90,000
The banks created 9x the original deposit.
This is the "money multiplier" in action.
This is not a thought experiment. This is how the modern monetary system actually works. Most of the money in your economy — roughly 90% or more — was created by commercial banks through lending.
"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, Quarterly Bulletin, 2014
The Paradox of Banking
Banking contains a deep paradox.
On one hand, money creation through lending is the engine of economic growth. Without bank credit, businesses could not invest, homebuyers could not buy homes, farmers could not buy seed. The money created by banks funds the real economic activity that produces goods and services.
On the other hand, this same process is inherently fragile. Banks are always in a precarious position — they have long- term assets (loans that will be repaid over years) but short-term liabilities (deposits that can be withdrawn on demand). This mismatch means they are always vulnerable to a loss of confidence.
And the money they create is not backed by physical reality. It is backed by promises — promises to repay loans. When those promises are kept, the system works beautifully. When they are broken on a large scale — when borrowers default, when asset values crash, when confidence evaporates — the system can collapse, as it did in 2008.
The history of banking is the history of this tension: the extraordinary productive power of money creation balanced against the extraordinary destructive power of its collapse.
What Banks Should Do vs. What They Actually Do
In theory, banks should:
- Take deposits from savers
- Lend to productive borrowers
- Charge a moderate interest rate that covers their costs and compensates for risk
- Maintain adequate reserves
- Serve the real economy
In practice, banks often:
- Chase the highest returns, not the most productive uses
- Lend excessively during booms and contract lending during busts (procyclical behavior)
- Create complex financial products that disguise risk
- Pay enormous bonuses to executives while socializing losses (taxpayer bailouts)
- Neglect small borrowers (farmers, small businesses) in favor of large, profitable clients
The gap between what banks should do and what they actually do is one of the central problems of modern economics. It is why banking regulation exists — and why it is always contested.
Think About It
Your bank balance says Rs. 50,000. But the bank has lent out most of it. Is the money "real"? What does "real" even mean when we talk about money?
If banks create money when they lend, and destroy money when loans are repaid, what happens to the money supply during a recession when fewer loans are made and more are called in?
Bank nationalization in India (1969) was meant to democratize credit. Did it succeed? What were the trade-offs?
A bank earns profits on money it creates from nothing. Is this fair? Who benefits, and who bears the risk?
The Bigger Picture
We have uncovered one of the most remarkable facts in economics: banks do not just store money — they create it.
Every loan is an act of money creation. Every repayment is an act of money destruction. The money supply of a modern economy is largely determined not by the government's printing press but by the lending decisions of thousands of banks, each making individual judgments about who to lend to and how much.
This system has produced extraordinary economic growth over the past several centuries. It has also produced devastating crises — bank runs, credit collapses, and financial panics that have thrown millions into poverty.
The goldsmith's discovery — that you can lend out what others have deposited — was simple, even obvious. But its consequences have shaped the modern world as profoundly as any invention in human history.
In the next chapter, we will follow the money further. We know that banks create money through lending. But lending is just another word for credit — and credit, as we will see, is both the engine that drives economic growth and the trap that can destroy it.
