Impermanent Loss Explained Simply
Bottom line: the "I should have just held" effect
Impermanent loss (IL) is what can happen when you deposit assets into a DeFi liquidity pool: because the pool automatically rebalances as prices move, you may end up with less value than if you had simply held the assets.
Key points
- You deposit two assets as a pair into a liquidity pool
- When one asset's price moves, the pool sells some of it to keep a set ratio
- The gap versus "just holding" is the impermanent loss
- Trading fees can offset it — but there is no guarantee
Why it happens
An automated market maker (AMM) pool keeps a mathematical ratio between two assets and trades automatically to maintain it. If one asset rises, the pool sells it for the other — so you end up holding less of the asset that went up, leaving you worse off than a simple hold.
Why "impermanent"
If the price returns to where you deposited, the loss disappears — hence "impermanent." But if you withdraw while prices have diverged, the loss becomes permanent.
How to reduce it
- Use low-volatility pairs (e.g. two stablecoins)
- Check whether fee income is likely to beat IL
- Don't join pools whose mechanics you don't understand
High yields hide risk
A high "APY" is mostly fees and incentives — IL and smart-contract risk are separate. Never judge by yield alone.
