Aave Liquidations Explained Through Real On-Chain Events

By Chanuka Geekiyanage Oct 23, 2026

An Aave liquidation is the forced sale of a borrower’s collateral once a loan becomes too risky. It looks like a simple price-drop story, but three real events show otherwise. Thin collateral liquidity left Aave with bad debt in 2022, a market crash in October 2025 tested volume, and a misconfigured oracle in March 2026 liquidated positions with no crash at all. This article uses those cases to show what triggers liquidations, who pays, and which borrower habits matter most.

How an Aave Liquidation Works

Aave calculates a health factor from your collateral value, its liquidation threshold, and your total borrow value. Below 1, any wallet can liquidate you. There is no queue, grace period, or notification.

In Aave V3, up to 50% of the debt can be repaid when the health factor is between 0.95 and 1, and both collateral and debt exceed $2,000. Below 0.95, or when either side is under $2,000, up to 100% can be repaid in one call. The liquidator receives the repaid value in collateral plus a bonus set per asset by governance.

That bonus is your real cost. As an illustration, with a 5% bonus and $10,000 of debt, a 50% liquidation repays $5,000 and hands the liquidator $5,250 of your collateral.

Four things decide how a liquidation plays out:

Oracle price: Aave acts on its oracle, not exchange prices, so lag or error moves the trigger.
Collateral liquidity: Liquidators must sell what they seize, and thin markets make that lossy.
Threshold distance: Positions closest to the threshold fail first, whatever the cause.
Bonus size: A small bonus can leave liquidators unwilling to act when gas and slippage rise.

Three Real Events

November 2022: CRV and $1.6 Million of Bad Debt

A large borrower built a CRV-collateralized position the market could not absorb cleanly. EigenPhi found Aave’s oracle lagged Binance by about 10 minutes. It also found 21 liquidators took part, 75% of liquidations were under 1% of remaining debt, and the largest was 24%.

The 50% close factor was not the binding limit. Market depth was, because selling CRV into thin liquidity moved the price against liquidators. The result was roughly $1.6 million to $1.7 million of bad debt, per EigenPhi and Blockworks.

October 10, 2025: A Crash That Tested Volume

Aave reported more than $250 million liquidated that day, averaging about $68,000 per liquidation, with no downtime. Chaos Labs estimated about $10 million in liquidation bonuses, with $1 million going to the DAO treasury. Aave also notes its Umbrella first-loss fund, launched in June 2025, held over $250 million in staked assets that can be slashed to cover protocol debt.

The engine handled the load. For borrowers, that means liquidations execute quickly and against you.

March 10, 2026: An Oracle Error With No Crash

A misconfigured CAPO oracle undervalued wstETH by about 2.85%. CAPO caps the price of yield-bearing assets to prevent manipulation. Roughly $26 million to $27 million was liquidated, covering 10,938 wstETH across 34 accounts.

The protocol recorded no bad debt, and Lido contributors said wstETH itself was unaffected. Chaos Labs put the excess value taken by liquidators at 345 ETH. Aave said it recaptured 141 ETH from bonus revenue and 13 ETH in fees to compensate users.

Rekt called the positions healthy, while Aave’s founder said they were already close to their thresholds. The arithmetic supports the second view: a 2.85% price cut made any position with a health factor below about 1.03 liquidatable. Most were wstETH E-Mode loops, a strategy covered in looping leverage and liquidation risk.

Event	Trigger	Scale	Bad Debt	Main Lesson
Nov 2022	Thin CRV liquidity and oracle lag	Largest single liquidation about $5M	About $1.6M to $1.7M	Collateral depth beats close factor
Oct 10, 2025	Market-wide crash	Over $250M in one day	Engine kept running	Volume is manageable; your buffer is not
Mar 10, 2026	CAPO misconfiguration	About $26M to $27M, 34 accounts	None	Thin buffers fail on non-market errors

Aave V3, Aave V4, and Morpho Compared

Protocol	Liquidation Design	Strength	Weakness	Best For
Aave V3	50% close factor, 100% below 0.95, static bonus per asset	Battle-tested, deep liquidator network	Bonus changes need a governance vote	Liquid, established collateral
Aave V4	Variable bonus that rises as health factor falls	Better targeting of risky positions, per Aave’s design post	Newer, so verify live availability	Users comfortable with newer architecture
Morpho	Per-market parameters, one immutable LLTV, no close factor	Predictable, fixed rules	A liquidator may repay part or all of the debt	Borrowers who prefer isolated markets

Parameters change through governance, so confirm current values in each protocol’s docs before depositing.

What to Check Before You Borrow

Oracle setup: Find which feed and caps apply to your collateral, especially yield-bearing tokens like wstETH.
Market depth: Check how deep the collateral’s liquidity is.
Liquidation price: Calculate it for a market move and for a small oracle error.
Liquidation bonus: A larger bonus means a larger penalty on every liquidation.
The 0.95 line: Below it, your whole debt can be repaid in one call.

My Take

Aave’s liquidation engine is its strongest component. October 2025 showed it handles volume, and March 2026 produced no bad debt and a compensation process. The weak point is borrower buffers.

For volatile collateral against stablecoins, I would not run below a health factor of about 1.6 to 2.0. That is my judgment, not an Aave recommendation. For correlated loops, I would keep enough room to survive a 5% oracle or depeg error, which means a health factor well above 1.05.

Avoid maximum-LTV loops unless you can monitor them constantly and repay fast. Choose Morpho’s isolated markets only if you value fixed rules over Aave’s liquidity.

Conclusion

Aave liquidations are predictable in mechanism and unpredictable in trigger. Collateral depth, a market crash, and an oracle error caused the three events, and the borrowers closest to the threshold lost the most.

Calculate your liquidation price today, add a buffer for oracle error as well as price movement, and keep a quick way to repay or add collateral. Do not rely on compensation, which happened in March 2026 but is not guaranteed.

FAQs

1. Can I be liquidated on Aave even if the market did not move?

Yes. On March 10, 2026, a CAPO oracle misconfiguration undervalued wstETH by about 2.85% and liquidated 34 accounts without a matching market move.

2. How much of my loan can be liquidated at once?

Up to 50% when your health factor is between 0.95 and 1 and both collateral and debt exceed $2,000. Below 0.95, or when either side is under $2,000, up to 100% can be repaid in one call.

3. Do liquidated borrowers get compensated when it is Aave’s fault?

Not automatically, and any payout depends on the incident and a governance or risk-provider decision. After the March 2026 event, Aave said it recaptured 141 ETH in bonus revenue plus 13 ETH in fees to compensate affected users.

4. Does a liquidation mean Aave lenders lose money?

Usually not, but lenders are exposed when collateral is too illiquid to sell quickly, as in the November 2022 CRV case that left about $1.6 million of bad debt. Aave also added Umbrella, a first-loss fund with over $250 million staked, to absorb such shortfalls.

5. How can I reduce liquidation risk before a volatile weekend?

Repay part of the debt or add collateral so your health factor can absorb a sharp drop and a delayed oracle update. Check your liquidation price in advance, since liquidations come with no warning.
