The Proof That Banks Create Money
“Where does money come from? 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 in which they are created is through commercial banks making loans: whenever a bank makes a loan, it creates a deposit in the borrower’s bank account, thereby creating new money. This description of how money is created differs from the story found in some economics textbooks.“ (Bank of England)
What the Bank of England says about Money Creation:
What Is Money?
“Economic commentators and academics often pay close attention to the amount of ‘broad money’ circulating in the economy. This can be thought of as the money that consumers have available for transactions, and comprises: currency (banknotes and coin) — an IOU from the central bank, mostly to consumers in the economy; and bank deposits — an IOU from commercial banks to consumers.
“Currency [bank notes and coins] only accounts for a very small amount of the money held by people and firms in the economy. The rest consists of deposits with banks.
“97% of the money held by the public is in the form of deposits with banks, rather than currency.” (Bank of England - Money in the modern economy: an introduction)
So most of the money in our economy is made up of bank deposits – the numbers that you see when you check your balance. And bank deposits are a IOU – a promise to pay, or in accounting terms, a liability – from the bank to you. But it would be wrong to think of these deposits as simply a representation of the cash that the bank owes you; in fact, these deposits function as money:
“In the modern economy, bank deposits are often the default type of money. Most people now receive payment of their salary in bank deposits rather than currency. And rather than swapping those deposits back into currency, many consumers use them as a store of value and, increasingly, as the medium of exchange.
“For example, when a consumer pays a shop by debit card, the banking sector reduces the amount it owes to that consumer — the consumer’s deposits are reduced — while increasing the amount it owes to the shop — the shop’s deposits are increased. The consumer has used the deposits directly as the medium of exchange without having to convert them into currency.” (Bank of England: Money in the modern economy: an introduction)
How is Money Created?
“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. Whenever a bank makes a loan, it simultaneously creates a matching deposit in the borrower’s bank account, thereby creating new money.”
“Commercial [i.e. high-street] banks create money, in the form of bank deposits, by making new loans. When a bank makes a loan, for example to someone taking out a mortgage to buy a house, it does not typically do so by giving them thousands of pounds worth of banknotes. Instead, it credits their bank account with a bank deposit of the size of the mortgage. At that moment, new money is created. For this reason, some economists have referred to bank deposits as ‘fountain pen money’, created at the stroke of bankers’ pens when they approve loans.(1)” [our addition in brackets] (Bank of England, Money Creation in the Modern Economy)
In short, money exists as bank deposits – IOUs of commercial banks – and is created through some simple accounting whenever a bank makes a loan.
Banks aren’t Middlemen between Savers and Borrowers:
There is a common idea – even taught in many economics textbooks and academic papers – that banks are simply middlemen (‘intermediaries’) between savers and borrowers. But this is inaccurate. As the Bank of England describes:
“One common misconception is that banks act simply as intermediaries, lending out the deposits that savers place with them. In this view deposits are typically ‘created’ by the saving decisions of households, and banks then ‘lend out’ those existing deposits to borrowers, for example to companies looking to finance investment or individuals wanting to purchase houses.
“In fact, when households choose to save more money in bank accounts, those deposits come simply at the expense of deposits that would have otherwise gone to companies in payment for goods and services. Saving does not by itself increase the deposits or ‘funds available’ for banks to lend. Indeed, viewing banks simply as intermediaries ignores the fact that, in reality in the modern economy, commercial banks are the creators of deposit money. This article explains how, rather than banks lending out deposits that are placed with them, the act of lending creates deposits — the reverse of the sequence typically described in textbooks.(3)” (Bank of England, Money Creation in the Modern Economy)
The Technical Details
This section covers all the nitty-gritty details of money creation by banks. We cover the three types of money, how balance sheets work, how central and commercial banks create – and destroy – money and what is wrong about the textbooks taught in universities. Read more…
“Refreshing and clear. The way monetary economics and banking is taught in many – maybe most – universities is very misleading and this book helps people explain how the mechanics of the system work.”
- Professor David Miles, Monetary Policy Committee, Bank of England
Why our monetary system is broken, and how to fix it.
“Money is a social invention, indeed among the most important of all social inventions. At present the right to create money has been handed over to the private businesses we call banks. But this is not the only way we could create money and, as recent experience suggests, it may be far from the best one. Read this book with an open mind and you will understand why.”
