Bad Debt Mutualization
Bad debt mutualization is a risk management mechanism where the losses from unrecoverable loans are distributed across a pool of lenders or stakeholders within a protocol. Instead of the protocol absorbing the loss through a central reserve, the impact is shared among those providing liquidity to the affected asset pool.
This approach is designed to align incentives, as it encourages liquidity providers to monitor the riskiness of the assets they support. If a borrower defaults and the collateral is insufficient to cover the debt, the lenders' balances are proportionally reduced to cover the deficit.
While this protects the protocol's core solvency, it introduces a layer of risk for passive liquidity providers. This model is often seen in decentralized lending markets where the risk of systemic failure is managed through collective participation.
It serves as a decentralized alternative to traditional insurance funds.
