Understand fractional reserve banking, reserve ratios, and the money multiplier effect using interactive sliders.
An economics math tool demonstrating money creation in commercial banking. Features deposit-and-loan sliders, adjusting reserve requirements, and visualizing the compounding lending cycles through Recharts bar graphs.
Designed for direct use without extra steps or inflated trust claims.
Learn how commercial banks expand broad money supply through fractional reserve lending cycles.
The process begins when physical cash is deposited into a commercial bank. For example, depositing ₹10,000 cash places legal base money into the bank's vault.
The process begins when physical cash is deposited into a commercial bank. For example, depositing ₹10,000 cash places legal base money into the bank's vault.
Banks are not required to keep all deposits in vaults. They hold a fraction (the Reserve Ratio) and classify the rest as Excess Reserves, which are legally eligible to be lent out.
The bank lends out its Excess Reserves. The borrower spends the loan, and the seller deposits the funds into Bank 2. Bank 2 reserves a fraction and lends the rest. This creates a compounding lending chain.
As deposit-loan-deposit rounds repeat, the broad money supply expands significantly. However, if depositors simultaneously demand withdrawals (a bank run), the bank may not have enough reserves to cover all withdrawals.

It operates as a lightweight, clean, and zero-latency sandbox designed for daily productivity.
Step 1: Define Initial Cash Deposit
Input the initial physical cash amount deposited into the banking system.
Step 2: Adjust Reserve Requirement
Slide the Reserve Ratio control to set the reserve percentage banks must hold in cash reserves.
Step 3: Run Iterative Lending Cycles
Observe how banks retain the required reserve and lend out the remaining excess reserves, expanding broad money.
Step 4: Analyze Multiplier Calculations
Examine the charts to see the total expanded money supply contrast against the base cash deposit.
Fractional reserve banking is a system where commercial banks only keep a fraction of their depositors' funds in cash reserves (held at the central bank or vault) and lend out the remaining excess reserves to borrowers.
When a bank issues a loan, it does not give out physical cash. Instead, it writes a digital credit to the borrower's account. This credit increases the total amount of checkable bank deposits in the economy, effectively creating new book money.
The money multiplier represents the maximum factor by which money supply can expand. It is calculated as 1 divided by the reserve requirement ratio (Multiplier = 1 / Reserve Ratio). For example, a 10% reserve ratio yields a multiplier of 10.
