What is Impermanent Loss? Impermanent loss is the reduction in value a liquidity provider experiences when the prices of pooled tokens diverge, compared to simply holding the same tokens outside the pool.
Impermanent Loss Explained Say you deposit equal values of two tokens into a liquidity pool. The pool constantly rebalances as people trade against it.
If one token's price rises sharply, the pool automatically sells some of the winner for the loser to stay balanced. When you withdraw, you hold less of the token that went up and more of the one that did not.
The result: your position is worth less than if you had just held both tokens in your wallet. That gap is impermanent loss. It is called impermanent because it shrinks or disappears if prices return to their original ratio, but it becomes permanent the moment you withdraw.
What Impermanent Loss Means For Audience
Use Case
Liquidity providers and yield seekers
Understand the real risk-adjusted return of providing liquidity, after netting fees against divergence loss
DeFi protocol teams
Design pool types and incentives that account for LP risk, since unmanaged impermanent loss drives LPs away
Analysts and researchers
Model whether fee income in a pool historically compensates LPs for divergence risk
Examples An LP provides ETH and a stablecoin, ETH doubles in price, and the LP ends up with less value than if they had simply held the ETH.
A stablecoin pair pool shows near-zero impermanent loss because both assets track the same price.
An analyst calculates that a pool's trading fees only offset impermanent loss for LPs who stayed longer than three months.
A protocol introduces concentrated liquidity ranges, increasing both fee income and impermanent loss risk for active LPs.
FAQs Why does impermanent loss happen? Automated market makers rebalance pools as prices move, effectively selling the appreciating asset and accumulating the depreciating one, leaving LPs worse off than holding.
Why is it called impermanent? Because the loss only becomes locked in when the LP withdraws. If token prices return to their original ratio first, the loss disappears.
Can fees make up for impermanent loss? Often yes, in high-volume pools. Whether providing liquidity is profitable depends on whether accumulated fees and rewards exceed the divergence loss.
Which pools have the least impermanent loss? Pools of assets that track each other, such as stablecoin pairs or wrapped versions of the same asset, since their prices rarely diverge.
How can liquidity providers manage impermanent loss? Choose correlated pairs, prefer high-fee high-volume pools, monitor positions actively, and treat advertised yields net of expected divergence loss.
