Aave Hits 100% Utilization Across All Core Markets — $5B in Stables Stuck

After the Kelp DAO exploit triggered a $6.6B withdrawal in 24 hours, Aave's USDT, USDC and WETH markets are fully utilized. TVL has fallen from $25B to $17.5B.

Aave's USDT, USDC, and WETH markets have all hit 100% utilization simultaneously, per CoinDesk — a protocol-wide condition that effectively freezes $5 billion in stablecoins ($3B USDT + $2B USDC) because no liquidity is available for withdrawals.

What's new

The trigger was the $293 million Kelp DAO rsETH bridge exploit on April 18. Attackers minted unbacked rsETH, pledged it as Aave collateral, and borrowed WETH. When Aave's markets caught up, users rushed the exits — $6.6 billion withdrew in 24 hours, dragging Aave's total value locked from a recent $25B peak down to $17.5B.

Why it matters

100%-utilization is a structural problem, not a transient one. Liquidation engines need spare liquidity to close undercollateralized positions; at 100% utilization, bad debt compounds. Without external intervention — either whale deposits or a governance action — the protocol cannot self-repair. Aave's WETH market was briefly frozen by governance and then unfrozen, a move CoinDesk analysts describe as "handing leverage to whales and illiquidity to everyone else."

The takeaway

This is the largest stress test of onchain lending since 2022. If Aave clears the backlog without protocol loss, DeFi's resilience story gets a strong data point; if not, the Jefferies thesis (see today's coverage) gets a very expensive proof point.
