Systemic Solvency Buffer

A systemic solvency buffer is an aggregate pool of capital or a reserve mechanism designed to absorb losses when individual liquidations fail to cover bad debt. In many lending protocols, this buffer is funded through a portion of liquidation penalties or protocol fees.

It acts as a final line of defense against insolvency caused by black swan events or rapid market crashes. When the liquidation engine cannot sell collateral fast enough due to lack of liquidity, the buffer provides the necessary funds to keep the protocol whole.

The size of this buffer is a critical indicator of a protocol's robustness and long-term viability. It helps maintain user confidence by ensuring that lenders can always withdraw their assets.

This mechanism is essential for mitigating the contagion effects of failed leveraged positions.
