Thin Buffers on Monad
LlamaRisk’s Oct. 9 snapshots show some Aave loans backed by yield-bearing collateral had little room before liquidation. On Monad, top suppliers of PT-$AUSD carried debt, and their health factors ranged from 1.01 to 1.18, with a median of 1.03. A health factor below 1 means liquidation is eligible. That is a thin cushion.
Borrowers often pair correlated collateral and debt to support larger positions, and Aave says lower health factors may be acceptable for correlated assets. But thin is thin.
The Monad collateral is PT-$AUSD-17DEC2026, a Pendle principal token that pays $AUSD at maturity. The reserve’s 30 million PT supply cap was fully used on Oct. 9. LlamaRisk recommended raising it to 60 million. A bigger cap lets more collateral in, but exit still depends on buyers or redemption.
Before maturity, Pendle’s route sells PT into SY, then redeems SY into a supported output token. After maturity, PT can redeem into SY without that market sale. Conversion into $USDC or USDT0 borrowed against it remains part of the process.
The pool was about 47% PT and 53% SY, so a large sale hits the opposite side. The oracle uses a linear discount to $AUSD/USD, which can follow a predictable path to maturity. A liquidator’s sale price depends on what the market will absorb. LlamaRisk’s launch note had a 95% liquidation threshold and 2.62% bonus in stablecoin E-mode. The bonus has to cover real conversion costs.
Arc Concentration and Redemption Queues
On Arc, two syrupUSDC positions held about 97% of supplied syrupUSDC, with health factors of 1.02 and 1.01. All debt among those suppliers was $USDC. That concentration means a few accounts drive demand for the collateral’s exit.
Arc had 59.63 million $USDC available in Aave at the snapshot, but that is debt-token inventory, not cash for syrupUSDC redemptions.
A local Uniswap V4 syrupUSDC/$USDC venue saw proceeds saturate near $500,000 as its $USDC side was exhausted, per LlamaRisk’s September assessment. Arc has no native redemption for this asset. A holder can sell locally or bridge to Ethereum and request redemption. The bridge alone was estimated at two to five minutes normally, with throughput around $10 million an hour. Maple’s withdrawal queue adds a separate wait. Most withdrawals take under 24 hours, but they can take up to 30 days.
For a liquidator using that route, Ethereum redemption and Arc debt repayment are separate stages. Someone must front $USDC to repay the Aave loan before the collateral exit pays back later. Bridge capacity, redemption cash, and financing duration all matter.
What the Caps Change
LlamaRisk’s Oct. 9 Arc proposal would raise the Maple Spoke $USDC draw cap from 23 million to 46 million and the syrupUSDC add cap from 25 million to 50 million shares. The draw cap was fully used, and the add cap was 87.8% used. Those caps set maximum capacity, not guaranteed liquidity. More deposits and borrowing depend on later activity.
The practical test for lenders is straightforward: compare recoverable collateral proceeds at a realistic liquidation size with debt repaid and total exit costs. Then ask who funds any redemption delay.
Monad’s PT needs a market sale before December maturity. Arc needs local buyers or an Ethereum exit with enough bridge capacity, redemption cash, and financing. The health factor shows proximity to liquidation. It does not show how fast the collateral can become cash.
