Under-Collateralization Risk
Under-collateralization Risk occurs when the value of a borrower's collateral falls below the required threshold to back their debt, potentially leading to bad debt for the protocol. This happens when the underlying collateral asset experiences a sharp price decline that is not offset by a timely liquidation.
In such cases, the protocol is left with an asset that is worth less than the debt it is meant to secure, threatening the system's solvency. This risk is amplified by high volatility, low liquidity, and delays in the price oracle updates that inform the system of current market values.
Managing this risk requires robust liquidation mechanisms, accurate price feeds, and careful selection of acceptable collateral assets. If a protocol fails to mitigate this risk, it can lead to a loss of confidence, potential bank runs, and systemic instability.
