Risk Stewards: Cap and IRM Changes on Aave V3 / 2026.09.09

Summary LlamaRisk recommends the following parameter changes based on user behavior, on-chain liquidity, and position health observed in the latest review of Aave V3 reserves. Increase the stablecoin Slope1 by 10 bps, excluding USDe. Increase the USDe base rate by 1% to 6% and decrease Slope1 by 1% on Core, Plasma, Monad, Mantle, and Avalanche. Decrease USDT0 Slope2 from 40% to 20% and increase supply cap for PT-USDG-29OCT2026 from 70M to 140M on X Layer. PT-USDG-29OCT2026 (Aave V3 X Layer) PT-USDG-29OCT2026 has reached 93.4% supply cap utilization on the Aave V3 X Layer instance. Supply Distribution Source: LlamaRisk, September 9, 2026 The top suppliers have a median health factor of 1.03. Borrowing is overwhelmingly denominated in USD₮0, with 55.1M of debt accounting for 98.7% of the total, followed by USDG. This debt is backed by PT collateral held within the isolated PT E-Mode categories, meaning the cohort is effectively holding stablecoin debt against a stablecoin-denominated PT. As a result, the health factor is driven primarily by the PT’s discount to par rather than by directional price movements. Liquidity Source: LlamaRisk, September 9, 2026 The primary trading venue is the Pendle AMM pool on X Layer, which holds 4.73M in total liquidity, split 88% SY and 12% PT. The SY side is the leg a liquidator draws from when selling PT, and it holds 4.17M against the 65.4M supplied to the reserve. Pool TVL has grown from close to zero in mid August and peaked near 8.1M at the start of September. The PT matures on October 29, 2026, after which it becomes redeemable at par against USDG, so the exit at maturity does not depend on secondary market depth. Recommendation The PT matures on October 29, 2026, after which it becomes redeemable at par against USDG. We recommend increasing the supply cap from 70M to 140M, which places the reserve at approximately 46.7% post-change cap utilization. Stablecoin Slope1 Increases The recommendation raises Slope1 by 10 BPS on sixteen stablecoin reserves across eleven deployments, continuing the Slope1 program in the stablecoin interest rate changes proposed by TokenLogic. The base rate, the optimal utilization point, and Slope2 are unchanged on every reserve. Instance Asset Utilization uOptimal Current Borrow APR New Borrow APR Delta Aave V3 Core USDC 94.0% 94.0% 4.30% 4.40% +10 BPS Aave V3 Core USDT 93.5% 94.0% 4.28% 4.38% +10 BPS Aave V3 Plasma USDT0 94.0% 94.0% 4.30% 4.40% +10 BPS Aave V3 Base USDC 88.9% 90.0% 4.54% 4.64% +10 BPS Aave V3 Arbitrum USD₮0 89.8% 90.0% 4.29% 4.39% +10 BPS Aave V3 Avalanche USDC 90.5% 90.0% 4.80% 4.90% +10 BPS Aave V3 Avalanche USDt 91.7% 90.0% 5.99% 6.09% +10 BPS Aave V3 Monad USDC 92.4% 92.0% 5.36% 5.46% +10 BPS Aave V3 Monad USDT0 92.0% 92.0% 4.35% 4.45% +10 BPS Aave V3 MegaETH USDm 89.8% 90.0% 4.29% 4.39% +10 BPS Aave V3 BNB Chain USDC 85.4% 90.0% 4.08% 4.18% +9 BPS Aave V3 BNB Chain USDT 82.4% 90.0% 3.93% 4.03% +9 BPS Aave V3 Gnosis USDC.e 77.4% 90.0% 3.70% 3.78% +9 BPS Aave V3 Optimism USDT 80.5% 90.0% 3.85% 3.94% +9 BPS Aave V3 Linea USDC 87.4% 90.0% 4.18% 4.27% +10 BPS Aave V3 Linea USDT 87.8% 90.0% 4.19% 4.29% +10 BPS These reserves carry approximately 6.18B in aggregate debt, and most run close to their optimal utilization, as shown in the table. Because Slope2 and the optimal utilization point are unchanged, the rate response above the optimal point shifts up by the same 10 BPS, and the incentive to repay or supply during a liquidity squeeze is preserved. USDe Interest Rate Model The recommendation raises the USDe base rate by 100 BPS to 6.00% on all five deployments that carry USDe, continuing the realignment set out in the stablecoin interest rate changes proposed by TokenLogic, which prices USDe borrowing in line with Ethena’s native staking rate. Slope1 comes down 100 BPS on all five, continuing the blend toward the 0.25% Slope1 in the same proposal. Instance Utilization uOptimal Current Borrow APR New Borrow APR Delta Aave V3 Core 32.3% 90.0% 5.72% 6.36% +64 BPS Aave V3 Plasma 22.4% 85.0% 5.79% 6.53% +74 BPS Aave V3 Monad 17.2% 90.0% 5.57% 6.38% +81 BPS Aave V3 Mantle 9.0% 85.0% 5.32% 6.21% +89 BPS Aave V3 Avalanche 69.9% 80.0% 6.75% 6.87% +13 BPS These five reserves carry approximately 323.8M in aggregate USDe debt against approximately 1.18B supplied. Because the optimal utilization point is unchanged on all five reserves, the share of supply held as withdrawal liquidity at that point is unchanged. X Layer Slope2 Reduction USD₮0 on Aave V3 X Layer sits at 89.5% utilization against a 90.0% optimal utilization point, with 60.6M borrowed against 67.8M supplied and 7.1M in idle liquidity, or 10.5% of supply. The recommendation reduces Slope2 from 40% to 20%, leaving the base rate, the optimal utilization point, and Slope1 unchanged. Because the reserve is below optimal utilization, the borrow APR remains unchanged. The change takes effect only above the optimal utilization point, where it halves the penalty applied to excess utilization.
