    Stablecoin Depeg & LP Stress

    Compare wallet loss, LP withdrawal value and impermanent loss without assuming a repeg.

    Who this is for: Someone holding a position in a stable pair, who already has a view on which side loses its peg and by how much. The tool prices that view; it does not form one.

    Choose a stress state, then compare holding with full-range LP withdrawal.

    Stress scenario, not a repeg forecast

    Values use the selected stressed prices. Fees, incentives, concentrated ranges, gas and exit execution are not included.

    How to use this stablecoin depeg impermanent loss calculator

    Compare a balanced stablecoin wallet with a full-range constant-product LP after one or both assets move away from one dollar. Stablecoin price loss and LP rebalancing loss are shown separately.

    Stablecoin loss versus impermanent loss

    A wallet loses value when either asset falls. Impermanent loss is only the LP's additional underperformance versus holding those same starting assets at the scenario prices.

    How the pool rebalances

    External price changes invite arbitrage until a full-range constant-product pool reflects the new relative price. The withdrawal amounts change even though the reserve product remains constant.

    No repeg assumption

    Each result values the assets at the selected stressed prices. It does not assume that either stablecoin returns to one dollar or estimate when that might happen.

    Stablecoin Depeg FAQ

    What happens to a wallet or LP position if a stablecoin loses its peg?

    Separate stablecoin price loss, constant-product LP rebalancing and impermanent loss under depeg scenarios. MoonMath labels the data basis for this tool as Formula, Model, Assumption.

    Is the Stablecoin Depeg a prediction or recommendation?

    No. The Stablecoin Depeg & LP Stress Simulator is an educational scenario tool, not financial advice, a recommendation, or a forecast. Provider coverage, liquidity, routing, fees and market conditions can make real outcomes materially different.

    Is every stablecoin depeg loss impermanent loss?

    No. The stablecoin price decline affects both holding and LP positions. Impermanent loss is the LP difference relative to holding the original asset amounts at the same stressed prices.
