[ARFC] - Chaos Labs Risk Parameter Updates - Aave V3 Avalanche - 2023.09.06

Simple Summary

A proposal to adjust five (5) total risk parameters, including Loan-to-Value, Liquidation Threshold and Liquidation Bonus across three (3) Aave V3 Avalanche assets.

Motivation

Chaos Labs’ Parameter Recommendation Platform runs hundreds of thousands of agent-based off-chain and on-chain simulations to examine how different Aave V3 risk parameters configurations would behave under adverse market conditions - and find the optimal values to maximize protocol borrow usage while minimizing losses from liquidations and bad debt.

Please find more information on the parameter recommendation methodology here.

The output of our simulations reveals an opportunity to optimize parameters for WAVAX, sAVAX and LINK.e on V3 Avalanche, resulting in improved capital efficiency of the system, with a negligible effect on the projected VaR (95th percentile of the protocol losses that will be accrued due to bad debt from under-collateralized accounts over 24 hours) and EVaR (Extreme VaR, the 99th percentile of the protocol losses that will be accrued due to bad debt from under-collateralized accounts over 24 hours)

Simulating all changes jointly yields a projected borrow increase of ~$26K, with a negligible increase in VaR and Extreme VaR compared to simulations with the current parameters.

Liquidity Analysis:

Based on our analysis, we have determined that there is adequate on-chain liquidity to support any significant liquidations with the updated parameters.

Positions Analysis

We have not identified any outsized positions that are actively affecting our recommendations.
