Impermanent Loss

Asset

Impermanent loss, a core concept in automated market maker (AMM) protocols and liquidity provision, arises from price divergence between an asset deposited and its value when withdrawn. This phenomenon occurs because AMMs maintain a constant product formula, requiring rebalancing of the asset pool as prices fluctuate externally. Consequently, liquidity providers (LPs) may realize a loss compared to simply holding the assets outside the pool, particularly during periods of significant price volatility. The magnitude of this loss is not necessarily permanent; a return to the initial price ratio can mitigate or eliminate it, hence the descriptor “impermanent.”
