Risk Stewards: Supply Cap Increases on Aave V3 / 2026.06.01

Risk
1

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.

Aave V3 Core:

  • Increase supply cap for WBTC from 31,800 to 38,200.

WBTC (Aave V3 Core)

WBTC is currently at 97.4% supply cap utilization (30,987 / 31,800) on the Aave V3 Core instance.

Supply Distribution

Top WBTC Suppliers Source: LlamaRisk, June 1, 2026

The top twenty WBTC suppliers run health factors between 1.15 and 9.01 with a median of 1.67, and nineteen of twenty carry outstanding debt. That debt is almost entirely stablecoin (USDT, USDC, and DAI dominate), so the cohort holds stablecoin borrowings against WBTC collateral whose HF stability tracks the BTC price.

Recommendation

We recommend raising the supply cap from 31,800 to 38,200 WBTC on Aave V3 Core. Supply has held near the 31,800 ceiling at 97.4% cap utilization, the proposed increase lands at approximately 81% post-change utilization, and the supplier base borrows predominantly stablecoins against WBTC collateral. The borrow cap is held unchanged at 4,000 WBTC (25% utilized).

bitcoin collateral showing a lot of promise. looking forward to seeing continued growth here. bitcoin seeking yield/borrowing power is a major theme.

No objections to this cap increase. The data supports it.

Analysis

WBTC on Aave V3 Core is at 97.4% supply cap utilization (30,987 / 31,800). The proposed increase to 38,200 drops post-change utilization to ~81%, which gives room for organic growth without immediately bumping against the ceiling again.

Three things to note:

1. The supplier base is healthy. LlamaRisk’s data shows the top 20 WBTC suppliers carry health factors between 1.15 and 9.01, with a median of 1.67. Nineteen of twenty hold outstanding debt, almost entirely in stablecoins (USDT, USDC, DAI). BTC-collateralized stablecoin borrowing is a conservative use case — the positions are directionally long BTC with stablecoin debt, which only liquidates on significant BTC drawdowns.

2. Borrow cap headroom is ample. The borrow cap stays at 4,000 WBTC with only 25% utilization. Supply cap increases without corresponding borrow cap pressure suggest genuine collateral parking, not leveraged looping that could create cascading liquidation risk.

3. The 20% increase is appropriately sized. A jump from 31,800 to 38,200 is a ~20% step-up. That’s within the standard Risk Stewards mandate and avoids the overshooting pattern where caps are raised 50-100% only to sit half-utilized for months.

From a tokenomics perspective, BTC remains the hardest collateral asset in DeFi — zero inflation risk (fixed supply, 21M cap), no governance token dependency, no rehypothecation depth beyond the WBTC wrapper itself. WBTC’s custodial risk (BitGo) is the primary concern, and that risk profile hasn’t changed. Our Asset Safety Tier (AST) framework scores WBTC favorably on Factor 1 (Redemption Posture: instant via BitGo), Factor 6 (Volatility: high but well-understood), and Factor 7 (Liquidity: deep across all major venues).

The one caveat worth monitoring: WBTC’s custodial model shifted in late 2024 when BitGo restructured its multi-jurisdictional custody arrangement. Aave’s prior risk assessment of the WBTC custody change was thorough, but continued monitoring of BitGo’s operational structure is prudent as BTC collateral grows past $3B+ in notional value on a single instance.

Position

Support. Routine, well-justified, appropriately sized. No concerns.
