Some Aave loans sit near liquidation with collateral that can take hours to cash out

Some Aave loans backed by yield-bearing collateral had narrow liquidation buffers in LlamaRisk’s Oct. 9 snapshots. Every top PT-AUSD supplier on Monad carried debt, while two syrupUSDC positions accounted for about 97% of supplied syrupUSDC on Arc. Cashing out the collateral involves a market sale or, for Arc holders choosing Ethereum redemption, a withdrawal queue that can take hours.

The two markets present separate versions of the same cash-flow problem. If a borrower becomes eligible for liquidation, a liquidator supplies the borrowed stablecoin, receives collateral and then recovers cash from it. December PT-AUSD requires a sale before maturity. Arc syrupUSDC offers a local sale or a bridge to Ethereum for redemption. An oracle valuation establishes collateral value within Aave; the exit determines what the liquidator can recover.

The Oct. 9 reviews of Monad and Arc recommend larger caps, making the economics of those exits consequential as borrowers seek room to grow.

Aave’s health factor compares collateral value, adjusted for liquidation thresholds, with debt. A position becomes eligible for liquidation below 1. The top Monad PT suppliers had health factors between 1.01 and 1.18, with a median of 1.03, in the Oct. 9 snapshot. USDC was their dominant debt asset, followed by USDT0.

Those readings leave a narrow valuation cushion for part of the cohort. They also reflect why borrowers pair correlated collateral and debt: smaller relative price changes can support higher leverage. Aave notes that lower health factors may be appropriate for correlated assets.

During liquidation, someone repays the borrower’s debt and receives collateral plus an incentive. The liquidator weighs the collateral’s realizable proceeds against the debt repaid, transaction and conversion costs, and the cost of financing any redemption wait. The health factor measures proximity to eligibility; a sale quote measures the exit.

The Monad collateral is PT-AUSD-17DEC2026, a Pendle principal token representing a claim on AUSD at its Dec. 17 maturity. The redemption entitlement is in the accounting asset. Receiving one AUSD still requires any conversion needed to obtain the USDC or USDT0 borrowed against it.

LlamaRisk reported that the reserve’s 30 million PT supply cap was fully utilized on Oct. 9 and recommended increasing it to 60 million PT. These limits measure token capacity. A larger cap would allow more collateral into Aave; its successful exit would still depend on buyers or redemption.

Before maturity, Pendle’s documented liquidation route sells PT into SY, its standardized yield wrapper, then redeems SY into a supported output token. After maturity, PT can be redeemed into SY without that market sale. Any further conversion into the borrowed stablecoin remains part of the route.

The Oct. 9 review describes the Pendle pool as 47% PT and 53% SY. A large PT sale draws from the opposite side of the pool, so a useful exit estimate needs the intended sale size, output and price impact across the full conversion.

Pricing adds another constraint. LlamaRisk says the December PT uses a linear discount oracle on AUSD/USD. Pendle’s linear-discount documentation describes a predictable path toward maturity independent of AMM prices. That valuation can follow its curve while a liquidator’s sale price depends on the market’s willingness to absorb seized PT.

LlamaRisk’s Oct. 2 launch recommendation specified a 95% liquidation threshold and a 2.62% bonus for the stablecoin E-mode, alongside a 93% borrowing limit. A liquidator has to compare the incentive applicable at execution with the actual cost of turning PT into the debt token.

The Arc comparison concerns syrupUSDC, a bridged share in Maple’s Ethereum yield-bearing vault. In the Oct. 9 Arc review, the two largest positions held approximately 97% of the supplied syrupUSDC at health factors of 1.02 and 1.01. All outstanding debt among syrupUSDC suppliers was USDC.

A few positions can therefore dominate demand for that collateral’s exit. The concentration refers to supplied syrupUSDC, while the stablecoin available to Aave lenders sits in a separate reserve.

Arc had substantial Aave liquidity at the snapshot: 143.45 million USDC added to the Core Hub, 83.82 million drawn and 59.63 million available. That available balance is debt-token inventory in Aave. Buyers of syrupUSDC and cash available for Maple redemptions determine other parts of the unwind.
