How Bank Lending Creates Currency
When a bank lends $50,000, where does the new account balance come from? Follow the records to discover what is created, who owes whom, and what happens when the loan is repaid.
The Deposit Is Created with the Loan
The bank creates the spendable balance it lends. That new deposit did not exist before the loan was made.
When a commercial bank makes a loan by crediting an account, it records a new loan and a new deposit together. It does not first have to transfer an equal deposit from another customer.
The borrower owes the bank on the loan. The bank, in turn, owes the account holder the deposit balance. This activity follows both obligations.
A note on terms: In this pack, “bank-created currency” means spendable bank deposits. Central-bank sources often call this deposit money and use “currency” more narrowly for notes and coins. Keep bank deposits, physical cash, and central-bank reserves distinct.
Identify What Is Created
Find the new deposit and the matching loan in the bank’s records.
Explain Who Owes Whom
Describe the borrower’s obligation to the bank and the bank’s obligation to the depositor.
Distinguish a Balance from Wealth
Explain why a larger account balance does not automatically mean greater net wealth.
Prepare the Activity
Suggested level: Ages 13–18, introductory. Learners need basic addition and subtraction. Use this as homeschool material, classroom enrichment, a summer learning session, or a small-group activity.
Time: Allow about five minutes to prepare before teaching. The core activity takes approximately 15 minutes. The extended option below brings the session to approximately 60 minutes.
Materials: Paper, a pencil, the student worksheet, and one shared screen with the Commercial Bank Credit Creation Simulator. A calculator is optional. A paper alternative is included below.
Curriculum preparation: Read Banking Fundamentals Lesson 1: Your Bank Deposit Is Actually a Loan, followed by Lesson 2: Whose Money Is the Bank Lending? Open the simulator and practise creating one loan before the session.
The scenario: A repair business borrows $50,000 to buy equipment. Its bank credits a new deposit account. The business has not yet spent the deposit.
Track only this transaction, ignoring fees and interest. The zero starting entries refer to this new transaction, not the bank’s entire balance sheet.
Something you own or an amount owed to you. The borrower’s deposit is a claim on the bank.
An obligation you owe. The borrower owes the loan, while the bank owes the deposit.
The amount borrowed that remains to be repaid, separate from interest and fees.
Assets minus liabilities. Consider both sides when an account balance increases.
Follow Both Sides of the Loan
The bank creates the deposit as part of making this loan. The $50,000 account balance did not exist beforehand. At the same time, the bank records the borrower’s promise to repay.
The borrower has an asset, a claim on the bank, and a debt to the bank. The bank has the loan as an asset and the customer deposit as a liability.
These entries create spending power, but they do not instantly create $50,000 of net wealth for the borrower.
Predict, Observe, and Explain
0–2 minutes · Make a prediction.
Ask: “Where will the $50,000 in the account come from?” Have learners write their prediction before explaining the answer. Introduce an asset as something owned or owed to you, and a liability as something you owe.
2–6 minutes · Create one loan.
Open the simulator and select Reset Simulation. Set Loan Amount to $50,000 and Credit Destination to Productive Investment. Select Create Commercial Loan once. Read the loan and deposit entries aloud.
6–8 minutes · Record what changed.
Complete the four records in the student activity below. Compare the new deposit with Existing Deposits Moved and Vault Cash Moved. Ask learners whether their original prediction needs to change.
8–14 minutes · Discuss the three questions.
Allow roughly two minutes per question. Work out the principal repayment in Question 3 on paper; the activity does not require a repayment control in the simulator.
14–15 minutes · Complete the exit sentence.
Ask learners to finish the sentence independently. Check whether they identify the new deposit and the borrower’s debt.
Keep the demonstration focused: The simulator’s asset-pressure and productive-growth percentages are illustrative model outputs. Use its accounting entries for this lesson. Those percentages are not measured effects or forecasts.
Teach it without a screen: Draw two records labeled “Bank” and “Borrower.” Add the entries below, then record $0 for existing deposits moved and $0 for vault cash moved. Ask the learner to explain each entry before completing the worksheet.
Loan receivable: $50,000 asset.
Customer deposit: $50,000 liability.
Bank deposit: $50,000 asset.
Loan owed: $50,000 liability.
Follow a Newly Created Loan
Write your answers on paper or use page 3 of the printable packet.
A repair business borrows $50,000. Its bank credits the business’s account. The business has not yet spent the deposit. Record only this new transaction, leaving out interest and fees.
First, predict: Where do you think the new account balance comes from?
Then, observe: For each record below, write the amount after the bank creates the loan. Keep your original prediction so you can compare it with the results.
Before the loan: $0.
After the loan: $________.
Before the loan: $0.
After the loan: $________.
Before the loan: $0.
After the loan: $________.
Before the loan: $0.
After the loan: $________.
Three Questions to Work Through
Use your recorded observations to support each answer.
Did the bank have to move $50,000 from another customer’s deposit to make this loan? What in your record supports your answer?
Who owes whom after the loan? Has the borrower become $50,000 wealthier just because the account balance increased?
On paper, repay $10,000 of principal from the unspent deposit to the same bank. What are the remaining deposit and loan balances?
The bank creates ______ when it lends.
The borrower receives ______ and owes ______.
Build a 60-Minute Session
Add guided viewing and a purchasing-power exercise to the short activity. Print pages 3 and 6 of the packet, and open the film and readings before the session.
Check the background first: The documentary’s study notes recommend completing Monetary Policy Lessons 1–6. Use the full-film session after that background, or provide guided support for unfamiliar concepts. You can also spread these activities across several days.
0–15 minutes · Complete the core activity.
Follow the short teaching sequence, including the three discussion questions and exit sentence.
15–37 minutes · Watch with a question in mind.
Watch How Our Monetary System Works, listed at 21 minutes, 17 seconds. Record one claim about bank lending or deposits and its timestamp. Save broader unfamiliar claims as questions for later investigation.
37–45 minutes · Check the claim.
Compare it with Banking Fundamentals Lesson 2 and the opening explanation in the Bank of England’s 2014 article. Identify exactly what the sources support, qualify, or leave unanswered.
45–55 minutes · Apply the idea of purchasing power.
Open Nominal Confusion. In the second post, read the section titled “What Is Nominal Confusion?” Complete the basket example below or on page 6 of the packet.
55–60 minutes · Reflect and choose a next question.
Explain how a spendable balance, a debt, and real purchasing power differ. Use evidence from both activities, then keep one unanswered question for the next lesson.
Connect the Lesson to the Evidence
Write your answers on paper or use page 6 of the printable packet.
1. Record a documentary claim.
Choose one claim about bank lending or deposits from How Our Monetary System Works. Write it in your own words and note the timestamp.
2. Compare it with a source.
Read the relevant explanation in Whose Money Is the Bank Lending? and the Bank of England article. Identify a passage that supports the claim, limits it, or leaves a question unanswered. Explain your reasoning.
3. Read and calculate.
Read “What Is Nominal Confusion?” in the second post of the Nominal Confusion topic. Then complete this separate, invented example. The contents of each basket stay the same.
Earlier: You have a $100 spending budget. One basket costs $10. How many baskets can you buy?
Later: You have a $120 spending budget. The identical basket now costs $12. How many baskets can you buy?
Compare: Does the larger budget buy more? Show your division or explain in words.
4. Make the connection.
Why are a spendable account balance, a debt, and real purchasing power different things? Use one detail from the loan activity and one from the basket example.
5. Choose your next question.
Write one question you would investigate further. Name a lesson or source that could help you begin.
Check Understanding
Expected observations: After one $50,000 loan, the loan receivable is $50,000 and the new customer deposit is $50,000. Existing deposits moved: $0. Vault cash moved: $0.
Question 1 · Was an existing deposit moved?
No equal deposit was transferred from another customer in this transaction. The bank created the new balance when it recorded the loan. The new $50,000 deposit and the $0 transfer entries distinguish creation from moving an existing balance.
Question 2 · Who owes whom?
The borrower owes the bank $50,000 on the loan. The bank owes the account holder $50,000 on the deposit. The borrower’s added asset and added liability offset at origination, so the loan alone adds $0 to net wealth in this simplified example. The deposit is spendable, but it is not earned income or a gift.
Question 3 · What happens on repayment?
After repaying $10,000 of principal from the unspent deposit to the same bank, the remaining deposit is $40,000 and the remaining loan principal is $40,000. Both the bank’s loan asset and its deposit liability decrease by $10,000. The deposit money used for that principal repayment is extinguished.
Exit sentence: Accept equivalent wording: “The bank creates a new deposit when it lends. The borrower receives a spendable balance and owes the loan principal.”
Documentary comparison: Answers depend on the claim selected. Look for an accurate paraphrase, a timestamp, a relevant source passage, and an explanation of what that passage establishes. A learner can identify an unanswered question without having to settle it immediately.
Purchasing-power example: $100 ÷ $10 = 10 baskets. $120 ÷ $12 = 10 baskets. The budget rises 20%, and the basket price also rises 20%, so the larger budget buys the same quantity. This example holds the basket’s contents constant and does not identify the cause of the price change.
Final reflection: A spendable balance is an asset the holder can use for payments. A debt is an obligation to repay. Purchasing power concerns what a balance can buy. In the loan example, the $50,000 balance comes with a $50,000 debt. In the basket example, a 20% larger budget buys no additional baskets.
Learning check: Mark each outcome as secure or revisit: identifies the new deposit; identifies both obligations; calculates the two $40,000 balances. If needed, repeat the relevant step with a $500 loan and a $100 principal repayment. Assess the explanation and evidence.
Keep the Explanation Precise
What “lending what it did not already have” means:
The bank issues a new deposit claim on itself. It creates the spendable balance provided to the borrower. This refers to the newly created deposit; the bank still needs resources to operate and meet its obligations.
Creation and settlement are different tasks:
A payment to another bank creates settlement needs. Banks also face capital and liquidity requirements, funding costs, borrower risk, demand for loans, and profitability considerations. The ability to create deposits does not make lending unlimited.
Keep the forms of money distinct:
This activity follows a loan credited to a deposit account. Physical notes and coins, central-bank reserves, and deposits created through asset purchases require separate explanations.
Separate principal from interest:
The repayment exercise concerns principal only. Interest has different accounting treatment. A one-loan example cannot establish that interest payments always require new borrowing.
Use evidence to extend the lesson:
The central-bank resources below describe their own jurisdictions. This worksheet isolates a shared accounting mechanism. Help learners distinguish an explanation of that mechanism from a policy opinion or a country-specific legal rule.
