Summary MSUSD traded near $0.378 on CoinGecko after falling far below its intended dollar peg. PeckShield said the Morpho msY/USDC market reached 100% utilization as liquidity concerns spread quickly online. MainStreet said assets remain fully backed, citing a third-party proof-of-reserves dashboard shutdown as cause publicly. Main Street USD traded at $0.3781 at the time of writing, with a 24-hour range between $0.065 and $0.9995. The move followed Accountable’s decision to end its service agreement with MainStreet.

PeckShield said the MainStreet-related token dropped as much as 85%, while CoinGecko data later showed a partial rebound from the day’s low. CoinGecko listed MSUSD with a market cap of about $27.06 million and 24-hour trading volume near $8.25 million. The token’s wide daily range showed unstable trading as holders tested liquidity and redemption confidence. Morpho market reaches 100% utilization The pressure also reached Morpho. According to PeckShield, the msY/USDC market hit 100% utilization, meaning available lending liquidity had been fully used. AlphaUSDC Delta V2, curated by AlphaPING, reportedly had about 30% exposure to the market, equal to roughly $18 million. That exposure drew attention because stress in one yield-linked market can affect lenders, vault depositors and borrowers using related positions. In lending markets, full utilization can make withdrawals harder and push borrowing rates higher. It can also leave users waiting for repayments or new deposits before liquidity normalizes. The issue does not prove that all related positions are impaired. It does show that a stablecoin depeg can quickly move from a token price problem into a wider DeFi liquidity problem. Accountable exit drives reserve concerns Accountable said it terminated the MainStreet service agreement immediately after the protocol failed to meet its standards. The statement removed a public verification layer that users had relied on to assess backing.
