How Do Banks Create Money Out of Nothing?

Where Does the Money Come From?

The obvious answer: from deposits. From savers. Your bank gathers thousands of people's savings, holds them carefully, and lends them to creditworthy borrowers. Someone's pension pot becomes your mortgage. The bank is a careful middleman — checking your income, your credit score, your deposit size before agreeing to pass along someone else's savings.

This is the story most of us carry. It appears in every economics textbook. It feels intuitively right: money has to come from somewhere. You can't lend what you don't have.

But sit with the mechanics of it for a moment.

If banks are truly just redirecting existing deposits, then every new mortgage would need a corresponding inflow of savings. When mortgage lending surges — as it did through the 2000s and 2010s — that would require a matching savings surge: millions of people simultaneously deciding to put more money in banks, which banks then lend to house buyers. That would be an enormous coincidence. And when interest rates fall and mortgage lending explodes across an entire country at once, you have to ask: whose savings is all this coming from?

The question isn't a gotcha. It's just: how does this actually work? Because once you look at what banks actually do when they approve a loan — in terms of their literal accounting — the answer is stranger and more interesting than the textbook version.

What Actually Happens When a Bank Makes a Loan

Here is what happens in a bank's accounting system on the day your mortgage is approved. Not what we've been told happens. What actually happens.

The loan officer clicks approve. Two entries appear in the bank's books simultaneously.

On the asset side of the bank's balance sheet: a new loan of £300,000. This represents money you now owe the bank. It is an asset to the bank because it generates a stream of future payments — your monthly mortgage — with interest.

On the liability side: a new deposit of £300,000 in your current account. This is money the bank now owes you. It is a liability to the bank.

Both entries appear at the same moment. One balances the other. This is double-entry bookkeeping, and it looks clean and orderly. But notice what did not happen: the bank did not find £300,000 sitting somewhere and move it into your account. No existing deposit was reduced. No reserve was drawn down. The bank created two new entries — a debt you owe them and a deposit they owe you — and both came into existence together.

The £300,000 in your account is new money. It did not exist yesterday.

The Balance Sheet: Writing Numbers Into Existence

Before your loan was approved, the bank's balance sheet showed some existing loans, some reserves, some deposits from other customers. After your mortgage is approved, it shows all of that plus one new loan and one new deposit — matching each other exactly. The bank is larger than it was before. It now has more assets and more liabilities. But it did not need to find new money before expanding. The expansion itself created the money.

This is not a trick or a loophole. It is simply how banking works. In 2014, Richard Werner ran an actual experiment: he borrowed money from a small German cooperative bank —Raiffeisenbank Wildenberg eG — and, with the bank's cooperation, monitored their internal accounts throughout the process. The bank did not transfer funds from anywhere. It created the loan by crediting his account — and the money did not exist before it did so. (Werner, “Can Banks Individually Create Money Out of Nothing?” International Review of Financial Analysis, 2014)

Loans Create Deposits, Not the Other Way Around

The textbook sequence: someone saves → bank collects the deposit → bank lends it out. Saving comes first. Lending follows.

The actual sequence: bank makes a loan → a new deposit appears in the borrower's account. Lending comes first. The deposit is the result of the loan, not its source.

This is why “loans create deposits” is the correct description. Your deposit did not fund someone else's mortgage. Someone else's mortgage created new money that now circulates as deposits in the banking system. The causal arrow runs backward from everything we were taught.

One way to feel how strange this is: if you pay off your mortgage early, that money is effectively destroyed. The loan is cancelled. The deposit that was created when the bank extended the loan disappears as the loan is repaid. New money comes into existence when banks lend. It leaves existence when loans are repaid. The total money supply in the economy is, at any moment, a reflection of the outstanding loans of the banking system.

The Bank of England Money Creation Explained

You might wonder: if this is how banking works, why didn't anyone tell us?

They did. The Bank of England published a paper in 2014 — “Money Creation in the Modern Economy” — written by three of their own economists, Michael McLeay, Amar Radia, and Ryland Thomas. It is not a fringe document. It is not a polemic. It is a sober, technical explanation of how the monetary system works, published in the Bank's own Quarterly Bulletin.

“Rather than banks receiving deposits when households save and then lending them out, bank lending creates deposits.”

And more directly:

“Whenever a bank makes a loan, it simultaneously creates a matching deposit in the borrower's bank account, thereby creating new money.”

This wasn't a leak. Nobody went to the press with a secret. It was published, in plain English, in an institutional document that anyone can read right now. The information was always available. It just wasn't in the textbooks.

The paper goes further. It explicitly contradicts what economics education has taught for generations: “In the modern economy, most money takes the form of bank deposits. But how those bank deposits are created is often misunderstood: the principal way is through commercial banks making loans.”

Often misunderstood. The Bank of England is being diplomatic. What they mean is: the thing you were taught in school is wrong, and we are now saying so in our official quarterly publication.

But What About Fractional Reserve Banking?

Some readers will have heard an alternative version of this story — one that feels more sophisticated than the simple “banks collect deposits and lend them out” story, but still not quite what we're describing here.

Fractional reserve banking is the model many economics courses teach as the slightly more accurate version: banks hold a fraction of deposits as reserves (say, 10%) and can lend out the rest. Your £1,000 deposit allows the bank to lend out £900, which becomes a deposit somewhere else, which allows that bank to lend out £810, and so on — a multiplier effect that creates money from an initial base.

This feels more sophisticated. There's a kernel of truth in it. But it's still wrong in an important way: it reverses the causal direction again.

In the fractional reserve model, the central bank creates base money (reserves), and commercial banks multiply it through successive rounds of lending. The reserves come first; the loans follow. But this is not how banks actually operate. Banks make loans based on whether they can find creditworthy borrowers at a profitable interest rate — not based on whether they have sufficient reserves. They make the loan first. Then they acquire the reserves they need to settle the payment — from the interbank market, from the central bank, from wherever they can find them.

Central banks have confirmed this. The Federal Reserve Bank of New York noted that “changes in reserves are unrelated to changes in lending.” The Fed explicitly retired the money multiplier from its own teaching materials because it does not describe how banks actually decide to lend.

This was not a new insight when the Bank of England published it in 2014. In 1954, Joseph Schumpeter wrote that it is “much more realistic to say that banks ‘create credit’ — that they create deposits in the act of lending — than to say that they lend the deposits that have been entrusted to them.” (Schumpeter, History of Economic Analysis, 1954) What economics textbooks taught in the following seventy years was not a misunderstanding. Someone decided what students should believe about where money comes from.

Who Actually Controls How Much Money Exists?

Once you understand that bank loans create money, a different question becomes important: who decides how much money there is?

The instinctive answer might be: the government, or the central bank. They print money. They set monetary policy. Surely they control the money supply.

But look at the numbers. In the UK, roughly 97% of money in circulation exists as bank deposits — numbers in accounts, not notes and coins. In the US, commercial bank deposits account for around 90–95% of the money supply. The cash you hold in your hand is a small fraction of total money. Almost all of it is bank-created credit.

The central bank sets interest rates — the price of borrowing — which influences how much banks want to lend and how much people want to borrow. But the central bank does not directly determine how much money is created. Commercial banks do, through their individual lending decisions. When Barclays decides to aggressively market mortgages, it creates new money. When banks collectively tighten lending standards after a crisis, money is destroyed — loans are repaid and not replaced, and the total falls.

The quantity of money in the economy — something that affects everyone's wages, prices, debts, and savings — is determined primarily by private institutions making decisions about who to lend to and at what price. Not by governments. Not by democratic processes. By banks deciding who is creditworthy and what kind of lending is profitable.

Where Does Newly Created Money Actually Go?

If banks create money, the next question is: what do they create it for?

The answer, across the last 40 years in most wealthy countries, is: property. In the UK, roughly 80% of bank lending has gone into mortgages and real estate — not into productive business investment, new manufacturing, or wages. (Ryan-Collins, Lloyd & Macfarlane, Rethinking the Economics of Land and Housing, 2017)

This is the direct mechanism behind why housing is so expensive. When banks create new money and direct it overwhelmingly at property purchase, more money chases the same fixed supply of land. Prices rise. The newly created money inflates the asset it was created to buy.

There is a further twist. Every pound of new money created by a mortgage is simultaneously a debt. You now owe £300,000 plus interest. The bank has a new income stream. Over 25 or 30 years, you will pay back considerably more than the original loan — perhaps £500,000 or more, depending on interest rates. The money that was created is extracted back, with profit, through the life of the mortgage.

So newly created money does two things simultaneously: it inflates the price of whatever it's pointed at (housing, in this case), and it creates a corresponding debt obligation for the borrower. The bank profits from both: rising property values secure the loan, and the interest payments generate income. Renters and new buyers pay for all of it — in higher prices and higher rents — while generating no corresponding wealth of their own.

Banks do this because it is profitable. When 80% of new lending goes into property, it is not because someone centrally decided that housing was more important than factories or hospitals. It is because lending against property is low-risk for the bank — the land is always there as collateral — and generates steady income for decades. The decision is made thousands of times a day, by loan officers and credit committees, and the cumulative result is that new money in the economy flows primarily into land prices. Not into wages. Not into schools. Into land.

If Banks Can Create Money, Why Is There Never Money for Hospitals?

If Barclays can create £300,000 on Thursday afternoon by approving a mortgage — money that literally did not exist on Wednesday — then what exactly is meant when a government minister stands up and says there is “no money” for nurses' pay?

Watch what happened in 2008. The US government found $700 billion for failing banks in a matter of days. The UK government guaranteed £500 billion. These were not funds that had been saved up. They were created. The political will existed, the numbers were typed, the money appeared. The same governments that spent a decade explaining that schools and hospitals would have to make do with less found, when banks were in trouble, that there was no limit.

The same thing happened in 2020. The UK furlough scheme paid 80% of wages for millions of workers for over a year. The US government sent stimulus checks to almost every adult in the country. Twice. The money was created. No one asked where it was coming from, because the alternative — mass unemployment and economic collapse — was politically unacceptable.

When a government says it cannot afford hospitals, it is making a choice about what is worth creating money for. Hospitals are not more expensive than bank bailouts. They are less politically urgent to the people making the decision. “We can't afford it” is not a financial statement. It is a statement about whose emergencies count.

The money supply is controlled by private banks making profit decisions — loans that serve shareholders — and by governments making political decisions. Neither set of decisions is natural or inevitable. Both reflect who has power over what gets funded, and who doesn't.
