+title: "Risk Parameter Updates GNO on V3 Gnosis"

+discussions: "https://governance.aave.com/t/arfc-chaos-labs-risk-parameter-updates-gno-on-v3-gnosis/17340"

+
+## Simple Summary
+
+A proposal to update GNO’s liquidation threshold, LTV, and debt ceiling on V3 Gnosis.
+
+## Motivation
+
+GNO has an average market cap of $445M and a daily trading volume of $3M over the last 180 days. Over this same timeframe, the largest single-day drop was 9.11%, with a daily annualized volatility of 63.75% and a 30-day daily annualized volatility of 94.46%.
+
+GNO is currently listed with relatively conservative parameters: 36% LT and 31% LTV. We recommend an increase to 50% and 45%, respectively. Following observations at these levels and utilizing our simulation platform, these parameters may be further optimized.
+Given current market conditions and utilizing our Isolation Mode Methodology we recommend doubling the debt ceiling to $2M.
+
+## Specification
+
+| Asset | Parameter    | Current    | Recommended |
+| ----- | ------------ | ---------- | ----------- |
+| GNO   | LT           | 36.00%     | 50.00%      |
+| GNO   | LTV          | 31.00%     | 45.00%      |
+| GNO   | Debt Ceiling | $1,000,000 | $2,000,000  |
