Blacklist Contagion

Blacklist contagion is the rapid spread of liquidity withdrawal from assets or addresses that have been flagged by centralized entities or automated protocol filters. When a major stablecoin issuer or exchange blacklists a specific address, it creates a ripple effect where other platforms automatically block interactions with those funds.

This creates a systemic risk where assets become frozen in place, preventing them from being traded or used as collateral. The fear of contagion forces market participants to avoid any address that has even a tangential connection to a blacklisted entity.

This defensive behavior significantly impacts market microstructure, as it can cause sudden liquidity crunches in affected pools.
