What is impermanent loss?
When you provide liquidity to an AMM (like Uniswap), price movements cause the pool to rebalance your tokens. If you withdraw when prices have changed, you receive less value than if you'd simply held — this difference is impermanent loss.
Why is it 'impermanent'?
The loss is only realized if you withdraw while prices differ from entry. If the price ratio returns to its original value, IL disappears. However, most LPs withdraw before prices revert, making the loss permanent in practice.
Can fees offset IL?
Yes — trading fees earned while providing liquidity can offset or even exceed the impermanent loss, especially in high-volume pools. Always compare expected fee APY against projected IL before depositing.
