Protocol Insolvency

Definition ∞ Protocol insolvency describes a state where a decentralized protocol lacks sufficient assets to meet its financial obligations. This can occur in systems that rely on complex economic mechanisms, such as lending protocols or algorithmic stablecoins, when market conditions deteriorate. Such a condition poses a significant risk to users and the broader digital asset ecosystem.
Context ∞ Protocol insolvency is a critical concern within the decentralized finance (DeFi) sector, often surfacing during periods of market stress. News reports frequently analyze the financial health of various protocols, particularly those that have experienced significant asset outflows or collateral devaluations. The potential for cascading failures due to insolvency is a key area of focus for risk assessment and regulatory scrutiny.
