Bank Run Contagion Simulator

Interactive 3D simulation of a banking crisis: trigger a bank run at one node of an interbank lending network and watch distress spread through exposure links, causing a cascade of failures across the financial system.

A financial crisis rarely starts everywhere at once — it starts with a run on a single bank and then spreads through the web of interbank lending that connects every institution to several others. This simulation models a network of banks holding mutual exposures: trigger a bank run on one node and watch capital losses ripple outward along exposure links, amplified by thin capital buffers and depositor panic, until either the system absorbs the shock or a cascade of failures takes down a large share of the network. Adjust connectivity, capital buffers and contagion strength to see what makes a financial system fragile versus resilient.
