A Morpho Blue lending vault is facing an $18 million loss after a sharp collapse in the msY token left depositors unable to withdraw from a concentrated USDC (CRYPTO: $USDC) strategy.
The AlphaUSDC Delta V2 vault, curated by AlphaPing, had built heavy exposure to the msY/USDC market tied to Main St Finance's msY token. The token fell as much as 85% on June 20, wiping out collateral value inside the market and pushing utilization to 100%.
In practice, that means all available liquidity has been borrowed, leaving depositors stuck while the market waits for repayment that may no longer be economically attractive for borrowers. The vault had been presented as a delta-neutral USDC strategy, but the collapse showed how quickly that label can break when collateral risk, concentration risk and liquidity risk sit inside the same market.

AlphaPing is now facing questions over how the vault's risk was managed. As curator, the firm controlled market selection, risk parameters and capital allocation, making its oversight central to the fallout. The scrutiny has deepened because its collateral verification service had reportedly been discontinued before the msY collapse.
The incident does not appear to have spread across Morpho Blue's wider protocol. Because Morpho uses isolated markets, the damage remains tied to the affected vault and its depositors rather than the broader lending system. That design limits contagion, but it also leaves users exposed to the quality of individual vault curation.
The loss lands at a sensitive moment for DeFi yield products, where stablecoin strategies are often marketed around lower volatility but still depend on collateral quality, active risk controls and sufficient exit liquidity. For Morpho, the broader protocol may keep operating as designed, but the AlphaUSDC Delta V2 collapse gives the market another reminder that permissionless lending can isolate losses without making them painless.
