# Aave risk stewards propose reserve-cap and USDe rate changes

> The proposal would raise Core USDC supply/borrow caps to 3.0B/2.7B, Prime wstETH supply cap to 80,000, Monad GHO supply/borrow caps to 60M/54M, and X Layer USD₮0 borrow cap to 90M. It would reduce three supply caps and raise USDe base rates while lowering Slope1 across five deployments.

## What happened

LlamaRisk published a specified package of reserve-cap and interest-rate changes for implementation through Aave's Risk Steward process.

## What changed

The proposal would raise Core USDC supply/borrow caps to 3.0B/2.7B, Prime wstETH supply cap to 80,000, Monad GHO supply/borrow caps to 60M/54M, and X Layer USD₮0 borrow cap to 90M. It would reduce three supply caps and raise USDe base rates while lowering Slope1 across five deployments.

## What did not change

The record does not demonstrate implementation. The proposed USDe optimal-utilization points remain unchanged; additional cap headroom does not itself create withdrawal liquidity.

## Confirmed

- The specification raises USDe base variable rates from 4% to 5% on Core, Plasma, Monad, Mantle, and Avalanche, paired with one-percentage-point Slope1 reductions.
- The proposed supply caps for Monad syrupUSDC, Monad USDe, and Plasma syrupUSDT are each 150M.
- The author identifies Risk Steward implementation as the next step.

## Still open

- Execution transactions and operative parameter values were not established.
- Post-change utilization, depositor concentration, and available exit liquidity remain to be assessed.

## What it means for an advisor

- Monitor execution and then refresh Aave diligence assumptions for deposit capacity, USDe borrowing costs, and withdrawal liquidity on affected deployments.
- Keep cap capacity separate from immediately available redemption liquidity in advisor explanations.
