This is the first of Gauntlet’s Quarterly Market Risk Reviews with the goal of keeping the community informed of market risk pertaining to Aave V2. This quarterly review complements Gauntlet’s previous monthly risk reviews. Over the last quarter (90 days), Gauntlet has executed seven (7) sets of parameter recommendations as part of our Dynamic Risk Parameters engagement. In addition, another set of parameter recommendations is currently live for voting, AIP-45.

Gauntlet’s Aave Risk Dashboard is live and running daily updates. The community should use the dashboard to better understand our methodology, recommendations, and how Gauntlet’s recommendations help reduce risk and increase capital efficiency for the protocol. We are particularly keen on iterating on this dashboard and would love feedback via this Google Form.

Highlights
- Average of 14% reduction in Value at Risk (VaR) with expected savings to users of $3,834,112 on Black Thursday volatility equivalent days
- Have saved Aave protocol users $303,139 in liquidations as a direct impact of lower liquidation bonuses, which equates to $1,651,429 on an annualized basis. It is important to note that this time frame experienced relatively low levels of asset volatility.
In addition, the community has asked for more explanation on the calculation of VaR. Our VaR metric for a single asset can be explicitly calculated as the sum of the insolvent value (USD) and the total liquidation volume (USD) for that asset in a simulation run. Insolvent value is defined as the total borrow value minus the total collateral value for any account where the total borrow value is greater than the total collateral value. Because we run many simulations, the VaR metric for each asset displayed on our dashboard for will be the 95% percentile value. The VaR for the entire system will be the sum of the VaR values acress each asset.

Gauntlet is closely monitoring market behavior and did not observe particularly unusual market behavior over this past quarter. We would, however, note that collateral usage for WETH and USDC has declined due to large liquidity providers pulling supply.
