💹 Financial Contagion Network (2D)

Canvas 2D interbank network lab: shock a bank and step through Eisenberg-Noe clearing rounds to watch default cascades ripple across random, ring, complete or core-periphery topologies.

What It Demonstrates

This 2D companion runs the same Eisenberg-Noe clearing model as the 3D original on a plain canvas graph: banks are nodes sized by assets, edges are interbank loans, and a click-driven shock-then-propagate loop resolves one clearing round per click until the cascade stops on its own.

How to Use

Set bank count, interbank density, shock size and capital ratio with the sliders, and pick a topology from the dropdown.
Click New Network to rebuild the graph, click any bank node to select it, then Shock Selected and Propagate to step through the cascade.

Did You Know?

A fully connected network absorbs small shocks better than a sparse ring — but past a critical shock size, that same dense connectivity turns into a superhighway for contagion.

⚙ Under the hood

A Canvas 2D interbank network: Eisenberg-Noe clearing computes each defaulted bank's loss and splits it across creditors in proportion to their exposure, iterating until no new defaults occur.
