How Do Banks Create Money? Banks don’t simply print money; they create it through lending activities, which are backed by assets and subject to various constraints. Money-central.com explains this process in detail, helping you understand the mechanics of money creation and its limitations in the financial system. Dive in to discover how banks really work and what it means for your finances, along with insights into financial management, wealth creation, and economic stability.
1. Understanding Money Creation by Banks
Do banks create money out of thin air?
No, while it might seem like banks create money out of nothing, the process is more nuanced. Banks create money when they make loans, simultaneously creating a matching deposit. This isn’t creating money “out of thin air,” but rather creating money backed by assets, such as the borrower’s promise to repay.
1.1 The Lending Process and Deposit Creation
When a bank issues a loan, it doesn’t simply transfer existing funds. Instead, it creates new money in the form of a deposit in the borrower’s account. This is based on the bank’s assessment of the borrower’s creditworthiness and the value of the asset backing the loan. According to a 2014 report by the Bank of England, this process is a key function of commercial banks in modern economies.
1.2 The Role of Commercial Banks
Commercial banks play a central role in money creation, far surpassing the role of central banks in this regard. They act as intermediaries, connecting borrowers and savers, and facilitating transactions in the economy. This activity is crucial for economic growth, as it channels funds towards productive investments.
1.3 Barclays-Pound Analogy
Consider using a credit card from Barclays to pay for coffee. In effect, you’re using a “Barclays-IOU,” denominated in GBP and accepted by the vendor. This Barclays-pound functions similarly to central bank-issued money, highlighting how commercial banks create and circulate money within the economy.
2. Debunking the Myth of Creating Money “Out of Nothing”
Is it accurate to say banks create money from nothing?
No, the idea that banks create money “out of thin air” is a common misconception. While the creation of money through lending might seem magical, it’s actually based on the creation of assets and is subject to various constraints.
2.1 The Double-Entry Bookkeeping Illusion
The simultaneous appearance of entries on both the liability and asset sides of a bank’s balance sheet can create the illusion of money being created from nothing. However, this is simply a reflection of double-entry bookkeeping, where every transaction affects at least two accounts.
2.2 The Importance of Asset-Backing
When banks create money, they do so based on assets. For instance, when a bank provides a loan, it’s creating money against the asset of the borrower’s promise to repay. This promise is not “nothing”; it’s a legally binding agreement with inherent value.
2.3 Parable of Lukas and Pontus
Consider Lukas, a PhD student, wanting to buy a pint. The pub trusts Pontus, Lukas’s supervisor, and accepts his IOU because Pontus has a reputation and assets backing his promise. Pontus isn’t creating money from nothing; he’s leveraging his credibility and assets.
3. Constraints on Money Creation
What factors limit banks’ ability to create money?
Banks can’t create unlimited amounts of money. Several factors constrain their ability to create money through lending, including regulatory requirements, market forces, and internal risk management policies.
3.1 Central Bank Reserves
A bank’s lending activity is limited by its holdings of central bank reserves. When a borrower uses the newly obtained funds to make a payment to someone with an account at a different bank, the borrower’s bank often has to use reserves to settle this transaction.
3.2 Household and Business Behavior
Households and businesses also play a role in money destruction through activities like loan repayment. For example, if someone takes out a new loan to refinance a mortgage, the net money creation would be approximately zero.
3.3 Risk Perception and Appetite
Various factors affect and limit the incentives for borrowers to take out loans and for banks to create money, including the parties’ risk perception and appetite, and the stance of monetary policy.
3.4 Capital Requirements
Banks are required to maintain a certain level of capital relative to their assets, limiting the amount of loans they can issue. These requirements, set by regulatory bodies like the Federal Reserve, are designed to ensure banks have enough resources to absorb potential losses.
3.5 Liquidity Requirements
Banks must also maintain a certain level of liquid assets to meet short-term obligations. This limits their ability to lend, as they must hold some assets in a readily convertible form.
4. Asset-Backing and the Role of Trust
Why is asset-backing essential for money creation?
Asset-backing is essential because it provides confidence in the value and stability of the money created. Without asset-backing, privately issued money wouldn’t be trusted or accepted as a means of payment.
4.1 Guaranteeing Parity with Central Bank Money
Privately issued money must be asset-backed to be traded at par with central bank-issued money, which comes in the form of currency or reserves. This parity is essential for the smooth functioning of the financial system.
4.2 Maintaining Pegged Exchange Rates
If a bank’s customers suspect it holds unhealthy assets or doesn’t have sufficient reserves, it can undermine the pegged exchange rate between the bank’s IOUs and central bank money, leading to a run on the bank.
4.3 Examples from the Global Crisis
During the Global Crisis, several banks, including Countrywide Financial in the US and Northern Rock in the UK, faced liquidity and solvency issues due to doubts about their asset quality. This underscores the importance of asset-backing in maintaining financial stability.
5. The Need for Public Money and Liquidity Transformation
How do banks access public money for liquidity transformation?
Banks require access to public money, such as central bank reserves, to engage in liquidity transformation or money creation. This access ensures they can settle transactions and maintain confidence in their IOUs.
5.1 Central Bank Reserves
Access to public money in the form of central bank reserves allows commercial banks to guarantee liquidity. These reserves are used to settle transactions between banks and provide a stable foundation for the financial system.
5.2 Alternative Liquidity Sources
Besides central bank reserves, commercial banks may also guarantee liquidity through alternatives such as their own equity or assets of high liquidity, like high-quality government bonds.
5.3 Role of Government Bonds
High-quality government bonds are treated akin to money by institutional investors such as pension funds, providing an additional source of liquidity for banks.
6. The Consequences of Unsound Asset Management
What happens when banks manage assets poorly?
If a bank holds unhealthy assets or lacks sufficient reserves, it can undermine confidence in its IOUs, leading to a run on the bank and potential insolvency.
6.1 Undermining Pegged Exchange Rates
Suspicion about a bank’s asset quality can undermine the pegged exchange rate between its IOUs and central bank money.
6.2 Potential for Bank Runs
This can lead to a run on the bank as customers rush to withdraw their deposits, causing the bank to become illiquid or even insolvent.
6.3 The Need for Bailouts
If banks could create money out of nothing, bailouts wouldn’t be necessary. The fact that banks sometimes require bailouts highlights the importance of asset-backing and sound risk management.
7. Contrasting Theories of Money Creation
What are the different theories about how money is created?
There are two main theories about money creation: the “endogenous money” or “loans first” theory, and the “reserves first” theory.
7.1 Endogenous Money Theory
The “endogenous money” theory posits that private banks create money through lending. This view is supported by the operational realities of modern banking, as explained by central banks like the Bank of England and Deutsche Bundesbank.
7.2 Reserves First Theory
The “reserves first” theory suggests that central banks choose the quantity of reserves available to private banks, which are then “multiplied up” in a stable ratio of broad money to base money.
7.3 Clearing Up Misunderstandings
Regardless of the specific theory, it’s important to understand that banks cannot create money out of nothing. Money creation is always linked to the creation of assets and is subject to various constraints.
8. The Role of Monetary Policy
How does monetary policy affect money creation?
Monetary policy, set by central banks like the Federal Reserve, influences the costs banks face in acquiring reserves and the demand for credit from households and businesses, thus affecting money creation.
8.1 Federal Funds Rate
In the US, the federal funds rate influences the costs banks face in acquiring reserves as well as the demand for credit coming from households and businesses.
8.2 Bank Rate in the UK
Similarly, the Bank Rate in the UK, the primary instrument of the Bank of England, influences the costs banks face in acquiring reserves and the demand for credit.

8.3 Impact on Borrowing and Lending
These monetary policy instruments affect the incentives for borrowers to take out loans and for banks to create money, influencing overall economic activity.
9. Addressing Common Misconceptions
What are some common myths about money creation?
Common misconceptions include the idea that banks create money out of nothing and that money creation is a limitless process.
9.1 Money Creation vs. Fairy Dust
Richard Werner (2014) writes that the money supply is created as “fairy dust” produced by banks individually, “out of thin air.” This is a metaphorical way of describing the process, but it can lead to misunderstandings if taken literally.
9.2 The Magic Money Tree
Zoe Williams (2017) in The Guardian suggests that all money comes from a magic tree, while David Graeber (2019) opines in the New York Review of Books that banks can and do create money literally out of nothing, simply by making loans.
9.3 The Reality of Asset-Backed Money
It’s crucial to understand that money creation by private banks is not magic, nor is it out of thin air. It’s based on the creation of assets and is subject to various constraints.
10. Practical Implications for Individuals
How does money creation affect individuals’ financial lives?
Understanding money creation can help individuals make informed decisions about borrowing, saving, and investing, contributing to better financial management.
