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.

Here’s a hypothetical situation: a hedge fund is making money, but one of its exchanges is about to liquidate its position anyway. Bitcoin has fallen, its short position on CME is profitable, and the matching long on Hyperliquid is bleeding cash. The two trades were designed to offset each other, but Hyperliquid can’t use profits sitting at CME to cover the losses on its own books. The fund has to find more collateral before the exchange closes the position for it.Moving money between exchanges takes time, and during a downturn, withdrawals can slow down or stop altogether. The fund could…
