Risk Parameter Updates for Aave V2 (2022-08-03)


Executed on 

Aug 14, 2022

Simple Summary

A proposal to adjust seven (7) total risk parameters, including Liquidation Threshold and Liquidation Bonus across four (4) Aave V2 assets.


This proposal is a batch update of risk parameters to align with the Moderate risk level chosen by the Aave community. These parameter updates are a continuation of Gauntlet’s regular parameter recommendations. Our simulation engine has ingested the latest market data (outlined below) to recalibrate parameters for the Aave protocol. Please note that this set of parameter changes will be lowering liquidation threshold for CRV and ENJ. The community has aligned on a Risk Off Framework regarding lowering liquidation thresholds.


This set of parameter updates seeks to maintain the overall risk tolerance of the protocol while making risk trade-offs between specific assets.

Gauntlet's parameter recommendations are driven by an optimization function that balances 3 core metrics: insolvencies, liquidations, and borrow usage. Parameter recommendations seek to optimize for this objective function. Our agent-based simulations use a wide array of varied input data that changes on a daily basis (including but not limited to asset volatility, asset correlation, asset collateral usage, DEX / CEX liquidity, trading volume, expected market impact of trades, and liquidator behavior). Gauntlet's simulations tease out complex relationships between these inputs that cannot be simply expressed as heuristics. As such, the input metrics we show below can help understand why some of the param recs have been made but should not be taken as the only reason for recommendation. The individual collateral pages on the Gauntlet Risk Dashboard cover other key statistics and outputs from our simulations that can help with understanding interesting inputs and results related to our simulations.

For more details, please see Gauntlet's Parameter Recommendation Methodology and Gauntlet's Model Methodology.

Aave V2 Parameter Changes Specification

Gauntlet's simulation engine will continue to adjust risk parameters to maintain protocol market risk at safe levels while optimizing for capital efficiency.

CRV Liquidation Threshold65%64%
DAI Liquidation Threshold80%85%
DAI Liquidation Bonus5.0%4.0%

See below volatility and exchange volume data from 07/01 to 08/03. These are valuable metrics to build intuition but are not the only inputs our simulations take into account to make parameter recommendations.

Notable Accounts to Flag

As of 8/8/2022, the data shows that no accounts would be liquidated as a result of these parameter updates. This could change if prices move significantly. On a daily basis, up until this proposal is executed, we will check whether these parameter updates will cause any liquidations and update the community on the forum post.

Risk Dashboard

The community should use Gauntlet's Aave V2 Risk Dashboard to understand better the updated parameter suggestions and general market risk in Aave V2. Gauntlet has also launched the Aave Arc Risk Dashboard.

Value at Risk represents the 95th percentile insolvency value that occurs from simulations we run over a range of volatilities to approximate a tail event.

Liquidations at Risk represents the 95th percentile liquidation volume that occurs from simulations we run over a range of volatilities to approximate a tail event.
