Aave's Risk Stewards have published a comprehensive review of reserve parameters across multiple V3 deployments, recommending targeted supply and borrow cap adjustments based on utilization metrics and collateral health patterns. The analysis reflects a deliberate approach to risk calibration—loosening constraints where demand signals justify expansion while tightening exposure where concentration risks have emerged. These changes underscore how mature lending protocols manage growth through data-driven governance rather than arbitrary expansion.

The most notable adjustment concerns Bitcoin Bridge (BTC.b) on Aave V3 Core, which has saturated at 99.7% of its 20 BTC supply cap. LlamaRisk recommends doubling this limit to 40 BTC, bringing utilization to roughly 50% post-change. The recommendation is grounded in sophisticated risk analysis: the top nine suppliers maintain health factors between 1.14 and 2.10, with eight actively borrowing stablecoins (USDe, GHO, USDT, USDC) against their collateral positions. Because all debt is stablecoin-denominated, the cohort's liquidation risk tracks Bitcoin price volatility rather than cross-asset correlation risk. The current saturation has created meaningful friction for additional collateral deployment, justifying the cap increase.

Ethena's USDe stablecoin shows divergent patterns across deployments, reflecting the protocol's varied adoption curve. On Mantle, USDe sits at 99.8% supply cap utilization but only 17% borrow cap utilization, suggesting strong deposit demand but limited derivative appetite. The recommendation doubles both caps—from 10M to 20M on supply and 9M to 18M on borrowing. Monad presents a more aggressive expansion, with caps quadrupling to 40M and 36M respectively, paired with a corresponding increase to sUSDe (staked Ethena). Conversely, Monad's mUSD reserve faces contraction: both supply and borrow caps are halved from 100M/50M to 50M/25M, indicating deteriorating health factor conditions among larger position holders that warrant tighter constraints.

These surgical adjustments reveal how risk frameworks operate beyond simple utilization thresholds. The Risk Stewards examine top depositor health factors, debt composition, collateral correlation, and reserve-specific liquidity conditions before recommending changes. The pattern of selective expansion combined with strategic reductions suggests that cap management is increasingly sophisticated, rewarding protocols with stronger fundamentals while managing tail risks in underperforming reserves. As lending markets mature, this granular approach to parameter governance will likely become standard practice across competitive protocols.
