Most money used by households and firms is not cash created at a printing press. It is bank deposits created on balance sheets.
Quick verdict: When a bank makes a loan, it typically creates a matching deposit. Lending is constrained by capital, risk, regulation, funding, settlement needs, borrower demand, profitability, and monetary conditions—not a simple fixed reserve multiplier.
Loans create matching balance-sheet entries
The borrower receives a deposit asset and owes a loan liability; the bank gains a loan asset and owes the deposit. Money and private debt expand together.
Payments create settlement needs
If the borrower pays someone at another bank, banks settle using central bank reserves or other funding arrangements. Liquidity management matters even though reserves are not lent to households.
Repayment destroys deposit money
Principal repayment reduces the bank loan and the payer’s deposit. Interest becomes bank income and affects other balance-sheet entries rather than reversing principal one-for-one.
A mortgage appears
A bank approves a €200,000 mortgage and credits the seller through the payment system. The bank holds the mortgage asset, funds settlement, carries credit risk, and must meet capital and liquidity rules.
What to remember
- Bank lending can create deposits.
- Reserves settle between banks.
- Capital, risk, funding, and demand constrain lending.
Test whether you understood it
Draw borrower and bank balance sheets at loan creation, external payment, and principal repayment. Track which asset and liability changes each time.
Where Sophros fits
Sophros can build the balance-sheet story gradually and connect it to central banking, inflation, and financial crises; central-bank publications should anchor claims.
Sophros.me builds connected, narrative-driven courses around the question you choose. Each lesson can be set from 3 to 15 minutes, which makes the format useful for a commute, a break, or a deliberate return to reading. Generated material can contain errors, so consequential claims should be checked against primary or authoritative sources.
A practical next step
- Learn balance-sheet entries.
- Separate deposits from reserves.
- Trace repayment and default.
The goal is not to collect one more finished page. It is to leave with a model you can explain without the page open. Close the tab, write the central idea in your own words, and name the question that remains unresolved. That small act separates learning from smooth consumption.
