MIM Stablecoin Crashes to $0.49: Abracadabra's Emergency Rate Hikes and What Really Happened

June 25: Accelerated collapse to $0.49 and emergency response

MIM plunged to approximately $0.48–$0.50, a drop of more than 50% from its $1 target . Blockchain security firm PeckShield recorded a 37.39% single-day drop to $0.4942 on June 25 .

Abracadabra Finance immediately declared emergency actions :

• Gradual interest rate hikes across all Cauldron lending markets, including deprecated markets, to incentivize borrowers to repay their MIM loans and reduce the circulating supply
• Suspension of all direct liquidity incentives — both Curve bribes and SPELL rewards — until MIM returns to a healthy peg
• No fixed end date for the emergency measures; they remain in effect until the peg is restored

The Incentive Mechanics

The depeg created a natural arbitrage window for borrowers. Since MIM traded at roughly $0.49 on the open market, anyone with a MIM loan from a Cauldron could buy MIM cheaply on an exchange and repay their 1:1 debt at a substantial discount . The rate hikes were designed to accelerate this behavior: higher borrowing costs make holding MIM debt more expensive, pushing borrowers to close positions sooner .

The Rapid Recovery

By late Wednesday (June 25), MIM had recovered to approximately $0.95, narrowing the depeg significantly after the emergency measures took effect . Multiple sources noted the rapid bounce as evidence that the rate-hike mechanism was working .

Broader Implications for DeFi Stablecoins

The episode reignited questions about the resilience of collateral-backed algorithmic stablecoins operating with limited market depth . Unlike fully fiat-backed stablecoins (e.g., USDC, USDT), MIM is minted against interest-bearing crypto collateral in CDP-style vaults, making it vulnerable to liquidity crunches when incentives shift or large positions unwind . The failure of a $100K direct liquidity injection to stabilize MIM at roughly $0.82 underscored just how thin the MIM Curve pool had become .

As one analysis noted, the episode was "the latest stress test for a smaller DeFi stablecoin" — one in which the protocol bet that shrinking the circulating supply could drag the token back toward $1 .

Protocol's Stated Priorities

Abracadabra stated its objectives were to :

• Restore market confidence in MIM
• Improve Cauldron market structure and liquidity depth
• Return MIM to a healthy dollar peg

The emergency measures remain in effect indefinitely until those goals are met.
