Your Bank Deposit Is a Loan
When you deposit money, who owes whom? Follow a deposit, a payment, and a withdrawal to discover what your bank balance represents.
Your Balance Records What the Bank Owes You
An ordinary bank deposit creates a creditor relationship: the bank owes the depositor.
When you deposit cash into an ordinary bank account, you receive a claim against the bank. Your account balance records that claim. It does not identify particular notes being stored in your name.
The same deposit is an asset for you because the bank owes you, and a liability for the bank because it must meet that obligation.
This activity develops the other side of the relationship explored in How Bank Lending Creates Currency. Learners take the roles of customers and a bank, then track how those obligations change.
Identify Who Owes Whom
Explain why the depositor is the creditor and the bank is the debtor.
Read Both Sides
Recognize the same deposit as a customer’s asset and a bank’s liability.
Follow the Changes
Track what happens to cash and account balances during a payment and a withdrawal.
Prepare the Activity
Suggested level: Ages 13–18, introductory. Learners need basic addition and subtraction. The activity can be used at home, in a classroom, during summer learning, or with a small group.
Time: Allow about five minutes to prepare and approximately 15 minutes for the core activity. Schedule the reading and documentary extensions separately.
Materials: Paper, pencils, and ten paper tokens, each labeled $100. Prepare three record sheets labeled Maya, Alex, and Bank.
Curriculum preparation: Read Banking Fundamentals Lesson 1: Your Bank Deposit Is Actually a Loan. If learners have completed the first teaching pack, ask them to recall why a customer deposit appeared on the liability side of the bank’s records.
The scenario: Maya starts with $1,000 in cash. Maya and Alex have ordinary deposit accounts at the same bank, both initially showing $0. Maya deposits the cash, pays Alex $200 through the bank, and then withdraws $100 in cash.
Keep the model clear: Track only the amounts involved in this exercise. The bank’s zero starting entries do not represent an actual bank’s entire balance sheet. Ignore fees, interest, overdrafts, and other transactions.
A person or institution to whom something is owed.
A person or institution that owes an obligation.
Something owned or an amount owed to you.
An obligation you owe to someone else.
Choose Your Roles
Copy these instructions onto separate slips of paper, or read them from the screen. One learner can work through every role with an adult. In a group, assign a different person to each role.
You begin with ten $100 cash tokens and a $0 deposit balance. Record your cash separately from the amount the bank owes you.
You begin with a $0 deposit balance at the same bank. When Maya pays you, record the amount the bank now owes you.
Keep the cash tokens you receive. Maintain separate records of the amounts owed to Maya and Alex. Update those records after each instruction.
After each stage, record the bank’s cash, Maya’s deposit, and Alex’s deposit. Ask each participant to explain what changed.
The Bank Is the Debtor
When Maya deposits $1,000 in cash, the bank receives the cash and owes Maya $1,000. Maya’s account balance records that obligation.
Maya is the creditor because the bank owes her. The bank is the debtor because it owes Maya. Maya has not borrowed $1,000 from the bank by making this deposit.
From Maya’s perspective, the deposit is an asset. From the bank’s perspective, that same deposit is a liability.
Deposit, Pay, and Withdraw
0–2 minutes · Make a prediction.
Ask: “If Maya deposits $1,000, does the bank owe Maya, does Maya owe the bank, or does nobody owe anything?” Have learners explain their prediction. Introduce creditor and debtor using “is owed” and “owes.”
2–5 minutes · Make the deposit.
Maya hands all ten cash tokens to the bank. The bank records $1,000 in cash and “Owed to Maya: $1,000.” Maya records “Cash: $0” and “Bank deposit: $1,000.” Ask both participants to describe the same deposit from their own perspective.
5–8 minutes · Pay another customer.
Maya instructs the bank to pay Alex $200. Because both customers use the same bank, update the records: reduce the amount owed to Maya by $200 and increase the amount owed to Alex by $200. Leave the cash tokens with the bank.
8–10 minutes · Withdraw cash.
Maya withdraws $100. The bank gives Maya one cash token and reduces the amount owed to Maya by $100. Alex’s balance stays the same. Record the remaining cash and deposits.
10–14 minutes · Discuss the results.
Work through the three discussion questions below. Ask learners to point to the records or tokens that support each answer.
14–15 minutes · Complete the exit sentence.
Let learners finish the sentence independently. Check that they correctly identify the creditor, debtor, asset, and liability.
Follow the Bank’s Obligation
Write your answers on paper. Keep a separate record for each stage so you can compare what changed.
Before you begin: Maya has $1,000 in cash. Both customer deposit balances are $0. The bank’s cash tracked in this exercise is $0.
Your prediction: After Maya deposits her cash, who will owe whom? What do you think her account balance will represent?
Record the results: Complete the amounts below as you carry out each stage. At the end, also record how much physical cash Maya holds.
Bank cash: $0.
Deposit owed to Maya: $0.
Deposit owed to Alex: $0.
Bank cash: $________.
Deposit owed to Maya: $________.
Deposit owed to Alex: $________.
Bank cash: $________.
Deposit owed to Maya: $________.
Deposit owed to Alex: $________.
Bank cash: $________.
Deposit owed to Maya: $________.
Deposit owed to Alex: $________.
Three Questions to Work Through
Explain each answer using the records you completed.
After the cash deposit, who owes whom? Explain why Maya’s deposit is her asset and the bank’s liability. Has Maya borrowed anything from the bank?
When Maya paid Alex $200 at the same bank, what happened to each deposit balance? Did the bank hand out any cash? Did its total deposit liability change?
After Maya withdrew $100, how much did the bank owe each customer? How much cash did Maya hold? Explain what she received in exchange for the reduction in her deposit.
I am the bank’s ______ because the bank ______ me. My deposit is an ______ for me and a ______ for the bank.
Check Understanding
After the deposit: The bank holds $1,000 in cash and owes Maya $1,000. Alex’s balance is $0. Maya holds no physical cash and has a $1,000 deposit asset.
After the payment: The bank still holds $1,000 in cash. It owes Maya $800 and Alex $200. Its total deposit liability remains $1,000.
After the withdrawal: The bank holds $900 in cash. It owes Maya $700 and Alex $200, for a total deposit liability of $900. Maya now holds $100 in physical cash as well as her $700 deposit.
Question 1 · Who is the creditor?
Maya is the creditor and the bank is the debtor. Maya’s deposit is an asset because it is an amount owed to her. It is the bank’s liability because the bank owes that amount. Maya has not taken out a loan from the bank in this activity.
Question 2 · What changed in the payment?
The bank reduced Maya’s deposit by $200 and increased Alex’s deposit by $200. It changed who was owed that amount. No cash left the bank, and the total amount owed to the two depositors stayed at $1,000.
Question 3 · What did the withdrawal do?
The bank repaid $100 of its obligation to Maya in cash. Maya’s deposit fell from $800 to $700, while her cash rose from $0 to $100. Her cash plus deposit still totaled $800 immediately before and after the withdrawal. Alex’s $200 deposit was unchanged.
Exit sentence: “I am the bank’s creditor because the bank owes me. My deposit is an asset for me and a liability for the bank.” Accept equivalent wording that preserves the relationship.
Learning check: Ask the learner to explain the deposit from both perspectives without looking at the role cards. Then ask them to explain why the payment changed two balances while the withdrawal changed both cash and a deposit.
Keep the Relationships Clear
A deposit remains an asset for the customer.
Calling a deposit a loan to the bank does not mean the customer has no property or no repayment rights. The customer holds a claim against the bank, rather than ownership of particular notes identified by the account balance.
This cash deposit changes the form of Maya’s money.
Maya gives up $1,000 in physical cash and receives a $1,000 deposit. Do not count the cash now held inside the bank as additional money still held by Maya. This exchange alone has not doubled the public’s spendable money.
A cash deposit and a newly issued bank loan have different matching assets.
In this activity, the bank receives cash and records a deposit liability. In the first teaching pack, the bank records a new loan asset and a new deposit liability. This paper exercise does not establish that banks must receive an equal cash deposit before lending.
The payment stays within one bank.
That is why the activity changes two customer balances without moving cash between banks. Payments involving another bank introduce settlement requirements that can be investigated separately.
The cash totals describe this exercise.
We have not modeled the bank’s lending, investments, other funding, or other customers. The activity therefore does not show a typical bank’s ratio of cash to deposits.
Creditor status and deposit protection can coexist.
Eligible deposits may be protected by deposit insurance, subject to the rules of the relevant country and scheme. For a United States extension, use the FDIC’s explanation of deposit insurance. Protection does not change the basic accounting relationship taught here.
Connect the Activity to the Lessons
Read · Banking Fundamentals Lesson 1
Read Your Bank Deposit Is Actually a Loan. Find the explanation of a bank balance as a claim against the bank. Rewrite it in your own words using Maya’s deposit as the example.
Compare · Banking Fundamentals Lesson 2
Continue to Whose Money Is the Bank Lending? Compare a deposit created after a cash payment into the bank with a deposit created when the bank makes a new loan.
Explain the connection: In both cases, what does the deposit represent for the customer? What does it represent for the bank? What asset does the bank record in each case?
Investigate · Payments between banks
Imagine Alex uses a different bank. What additional transaction would the banks need to arrange? Use the Deutsche Bundesbank’s explanation of money creation to investigate the difference between changing customer balances and settling a payment between banks.
Examine the Promises Behind the Balances
For a later session, watch Money as Debt Part II: Promises Unleashed, the documentary linked from Banking Fundamentals Lesson 1.
Plan the viewing: The film is listed at 1 hour, 16 minutes, 45 seconds, with the banking lessons 1–3 recommended beforehand. Schedule the full film separately from the 15-minute activity. A teacher can also preview it and select a relevant excerpt, recording the chosen start and finish times.
Before watching: Write one sentence explaining what Maya owns after depositing her cash and who owes the corresponding obligation.
During viewing: Record one claim about deposits, bank obligations, or the creation of bank money. Write the claim in your own words and note its timestamp.
After viewing: Compare that claim with the relevant curriculum lesson and one of the primary sources below. Identify a passage that supports it, qualifies it, or leaves a question unanswered.
Written reflection: “What does a bank balance promise, and how did our deposit, payment, and withdrawal activity help me understand that promise?” Use one example from the activity and one detail from your reading or viewing.
Teacher review: Look for an accurate description of who owes whom, a specific example, and a relevant source passage. Assess the learner’s reasoning and evidence, rather than agreement with every argument in the documentary.
Check the Explanation
Use these sources to check the meaning of a deposit and to distinguish the accounting relationship from questions about regulation, protection, or policy.
A 2014 introduction explaining money as a form of IOU and distinguishing currency, bank deposits, and central-bank reserves.
The section on modern forms of money identifies deposit balances as liabilities of financial institutions.
Further explanation of deposits, lending, and the funding needed to settle payments.
A United States resource explaining protection for eligible deposits at insured banks and the conditions of coverage.
Support Different Learners
Keep the relationships the same while adjusting the numbers or depth of discussion.
Use ten $10 tokens: deposit $100, pay $20, and withdraw $10. Begin with “the bank owes me” before introducing creditor and liability.
Keep separate pages for the bank and each customer. Explain every change aloud before checking the answer guide.
Explore how payments work across different banks, or research which deposit protections apply in your country using an official source.
Look at Both Sides of the Balance
Each time you see an account balance, ask: whose asset is this, whose liability is it, and what transaction created or changed it?
Use the replies below for questions about the activity or feedback from teaching it. Share which step helped learners understand the relationship and which questions they would like to investigate next.
