What Is “Impermanent Loss” and How Does It Affect the Risk Profile of Liquidity Provision?
Impermanent loss (IL) is the temporary loss of funds a liquidity provider (LP) experiences when the price ratio of the deposited tokens changes compared to simply holding them in a wallet. IL occurs because the automated market maker (AMM) forces the LP to sell the appreciating asset and buy the depreciating asset to maintain the 50/50 ratio.
While trading fees can offset IL, it introduces a significant, unique risk that must be factored into the expected return of liquidity provision.
