Crypto markets saw their biggest single-day liquidation event in months on May 28, with $958.8 million in positions forced closed, according to CoinDesk data. Nearly all of it — $897 million — came from long traders betting on higher prices. Shorts accounted for just $61 million. The wipeout comes during a stretch of heavy deleveraging: the week ending May 17 had already seen $563 million in long liquidations, primarily in Bitcoin and Ether.
DeFi lending pools feel the pressure
The pain isn't confined to futures markets. After the LayerZero/KelpDAO exploit, Aave has bled more than $5.5 billion in stablecoin supply outflows and $3.1 billion in stablecoin loan closures within two weeks, per Galaxy Research. In addition, withdrawals exceeded 25,400 BTC-equivalent units and 943,000 WETH — roughly $8.6 billion in total value leaving the protocol. The outflow is a textbook flight to safety: lenders pulling stablecoins, borrowers closing positions to avoid liquidation.
How liquidation cascades happen
The mechanics are brutal in thin markets. DeFi liquidation protocols use rule-based thresholds. Once a position's collateral value dips below the required ratio, bots swoop in to buy the collateral at a discount and close the loan. In a volatile environment, one liquidation pushes prices lower, triggering the next — a cascade. Liquidity evaporates fast because lenders yank stablecoins and traders slash inventory, which worsens margin calls. The May 28 event fits that pattern: a sharp move caught overleveraged longs, and the lack of buy-side depth amplified the damage.
What traders can do
Conservative loan-to-value ratios, diversified collateral, and pre-set alerts are the standard advice for avoiding forced closures. But the sheer size of the May 28 flush — nearly a billion dollars in a single day — shows that even careful traders can get caught when a cascade starts. With Aave's outflows still running and the LayerZero/KelpDAO after-effects unresolved, the market remains vulnerable to another leg down.
