Three-bank balance sheet dynamics

Bank Theory, Operations & Strategy · Lecture 2 · University of Stirling student simulator

Explore how lending and payments change three banks

Each bank obeys cash + loans = deposits + capital. A new loan creates a deposit at the lending bank. When that deposit is paid to another bank, deposits and settlement cash move between banks. All amounts are illustrative £ millions.

Start with the Lecture 2 example: Goodwin lends £4, then £1 is paid to Middleton and £3 to Hestor. Click Run lecture example to see the two steps.

Make a transaction

Transactions are applied only if the resulting cash, loans, deposits and capital remain non-negative. There is no automatic borrowing from the central bank. External cash deposits and withdrawals cross the boundary of this three-bank system.
