[ARFC] Chaos Labs Risk Parameter Updates - Aave V2 Ethereum - 2023.08.09

Governance
1

Simple Summary

A proposal to:

(1) Reduce the Liquidation Threshold (LT) and Loan-To-Value (LTV) for sixteen (16) frozen collateral assets on Aave V2 Ethereum.

(2) Increase Reserve Factors for all collateral assets on Aave V2 Ethereum.

Motivation

In line with our ongoing commitment to reducing the potential risks associated with V2 markets and promoting migration to V3, we suggest a phased wind-down of the frozen V2 markets. The following proposal is part of a series of proposals to reduce capital efficiency across V2 collateral assets.

The previous iteration of proposals:

LT Reductions

Implementing a gradual decrease in LTs effectively diminishes the borrowing power for the existing markets. This proposal offers the community two alternatives - a ā€œmoderateā€ and an ā€œaggressiveā€ approach for the preliminary LT reduction.

  • Aggressive (Chaos Recommendation) - This option suggests an LT configuration that optimizes reductions without significantly increasing the number of accounts eligible for liquidation. The proposed values are set at a margin of 8% from the closest LT figure, which would trigger more substantial liquidations.
  • Moderate - If the community leans towards a more tempered approach of slowly reducing the Liquidation Thresholds, we propose limiting the LT decrease to a maximum of 10%. Hence, we define the ā€œModerateā€ option as the minimum between 10% and the value suggested by the aggressive approach.

In the tables below, we share data to quantify the effect of the recommended reductions on protocol users:

Value liquidated Accounts liquidated
Aggressive $10,100 58
Moderate $8,580 43

As Liquidation Threshold reductions may lead to user accounts being eligible for liquidations upon their approval, we want to clarify the full implications to the community at each step. Chaos Labs will publicly communicate the planned amendments and list of affected accounts leading to the on-chain execution.

LTV Decrease

For assets where the LTV is not 0, we recommend maintaining the same buffer as the current configuration.

RF Increase

In line with our V2 to V3 migration plan, we propose another iteration of RF increases on Aave V2 Ethereum. By progressively increasing the reserve factors, the interest rate for supplying these assets on V2 will be increasingly less attractive, thus encouraging suppliers to transition positions to V3. In this proposal, we suggest an increase of 5% for all V2 collateral assets.

Next Steps

  1. Following community feedback, submit the ARFC for a snapshot vote for final approval.
  2. If consensus is reached, submit an Aave Improvement Proposal (AIP) to implement the proposed updates.

As of today, the following accounts and values are at risk of liquidation following the proposed changes.

Value liquidated Accounts liquidated
Aggressive $16,000 66
Moderate $13,500 52

The full list of accounts and their projected health score, given the updated LTs can be found in this sheet.

Thanks @ChaosLabs,

Given there isnā€™t a significant difference between ā€˜value liquidatedā€™ across aggressive and moderate we are supportive of the aggressive changes.

5

Given market volatility over the past few days, the impact of both the aggressive and moderate options on UX has intensified.
As of today, the following accounts and values are at risk of liquidation following the proposed changes.

Value liquidated Accounts liquidated
Aggressive $123,170 68
Moderate $103,380 51

We are reevaluating the proposal and will update the community on next steps.

As these recommendations are more conservative than the ā€œAggressiveā€ option which the community has previously voted on in the Snapshot vote, and to reduce governance overhead, we intend on moving directly to AIP, barring any community objections.

Please note that we have omitted LINK and DPI from this proposal, as reducing their LTs would put larger positions at risk of liquidation.

We have updated the Specification section in the original proposal to reflect the final recommendations of this proposal.
