Commercial Bank Credit Creation Simulator

Commercial Bank Credit Creation Simulator

Foundations Series • Banking Fundamentals • Interactive Lesson

Watch how a commercial bank creates a new bank deposit when it issues a loan. The key point is not that physical cash appears, but that a new bank deposit balance is created on the bank’s books at the same time a matching loan asset is recorded.

Core Principle A bank loan creates a new bank deposit — it does not need to move an equal existing deposit first.
Precision Note

This simulator is showing the creation of bank deposit money (spendable account balances), not the printing of paper cash. The borrower receives a newly created deposit liability of the bank.

Loan Controls

Credit directed toward existing assets may bid up asset prices without directly increasing the production of goods and services.

Loans Issued 0

Loan Creation Theater

The visual sequence below is the heart of the lesson: the borrower’s promise becomes a bank asset, and a matching deposit is created at the same time.

The borrower promises to repay the bank according to the loan terms.

Focus on the two key simultaneous entries: a new loan asset for the bank and a matching new deposit liability.

Key Clarification: No pre-existing customer deposit has to be transferred here. The new deposit is created on the bank’s books when the loan is recorded.

Credit Allocation Effects

Awaiting Loan Creation

The destination of credit influences whether new bank-created purchasing power tends to flow toward existing asset markets or productive activity.

Educational note: This simulator simplifies a complex banking system for teaching purposes. Real-world lending operates within capital, liquidity, legal, regulatory, collateral, and risk-management constraints that are not fully modeled here.
