Risk Propagation
Risk propagation is the mechanism by which a financial shock in one part of the system spreads to other, seemingly unrelated areas. This happens because of the interdependencies created by leverage, shared collateral, and common market participants.
For example, a liquidation on one exchange can lower the price of an asset, which then triggers liquidations on a completely different lending protocol. This rapid spread is characteristic of modern, high-speed financial markets where everything is digitally linked.
Risk propagation is often non-linear, meaning a small shock can lead to an unexpectedly large impact. It is a major challenge for regulators and protocol designers who aim to create stable systems.
By studying how risks move through the network, analysts can develop better safeguards and stress tests to prevent a localized issue from turning into a systemic failure.
