Risk Buffer
A risk buffer is the excess collateral held by a user or a protocol above the minimum required to maintain a position or ensure solvency. For a user, it represents the extra margin they have before they are liquidated.
For a protocol, it refers to reserve funds or over-collateralization that protects against market shocks and bad debt. The size of the risk buffer is a strategic decision that balances the desire for higher leverage against the need for safety.
A larger buffer reduces the likelihood of liquidation and insolvency but also limits the efficiency of capital usage. During periods of high market volatility, increasing the risk buffer is a prudent strategy.
It acts as a shock absorber, allowing the system to weather sudden changes in asset prices. Effective risk buffer management is a hallmark of sophisticated financial engineering in crypto.
