If you have ever explored DeFi platforms promising passive income, you have likely come across the term impermanent loss. It sounds complicated, but it simply describes one of the biggest risks liquidity providers face. While DeFi allows anyone to earn by supplying assets to liquidity pools, price changes in those assets can sometimes lead to unexpected losses.
Impermanent loss occurs when the value of your deposited tokens shifts after entering a pool. The good news is that this loss can be temporary and even offset by trading fees or rewards. In this article, we will break down what impermanent loss means, how it happens, and how you can manage it smartly while still earning from DeFi.
What Is Impermanent Loss?
Impermanent loss happens when the price of the tokens you put into a DeFi liquidity pool changes compared to when you added them. Because the pool automatically adjusts token ratios, the total value of your share may become smaller than if you had just kept the tokens in your wallet.
Imagine you put one coin worth £10 and another worth £10 into a pool. If one coin’s price rises or falls a lot, the pool changes the number of coins you own to keep things balanced. When you take your tokens out, they might be worth less together than if you had just held them. That difference is called impermanent loss.
The term impermanent implies that loss only becomes real if you remove your tokens before prices go back to normal. If the prices return to their original levels, your value also returns. In other words, the loss is temporary until you decide to withdraw your tokens.
How Does Impermanent Loss Work?
Impermanent loss happens because of how DeFi platforms manage liquidity pools. These pools use smart contracts to keep trading fair and balanced, but price changes can shift the value of the tokens inside. Understanding this process helps investors see why impermanent loss occurs when prices move up or down.
Liquidity Pools and Automated Market Makers
DeFi platforms such as Uniswap or SushiSwap use something called Automated Market Makers, or AMMs, to run their liquidity pools. These pools hold two types of tokens in equal value, such as ETH and USDT. The AMM automatically changes the amount of each token in the pool to keep its overall value balanced when traders buy or sell.
Price Changes and Rebalancing
When the price of one token goes up or down, the pool automatically rebalances the token amounts to keep a 50–50 ratio. This means you will end up holding fewer of the tokens that went up in price and more of the ones that went down. Even though this keeps the pool stable for trading, it can make your share of the pool worth less than if you just held both tokens outside.
The Role of Arbitrage Traders
Arbitrage traders help balance prices between DeFi pools and the broader crypto market. When the price of a token in a pool is different from the market price, traders buy or sell tokens to close that gap. While this keeps prices accurate, it also contributes to impermanent loss for liquidity providers, as token ratios shift during these trades.
Example of Impermanent Loss
Let’s look at an example to understand how impermanent loss works in a simple way. This will show how price changes can affect the value of your assets when you provide liquidity to a pool.
- Suppose you add 1 ETH and 2,000 USDT to a pool when ETH is worth 2,000 USDT. The total value of your deposit is 4,000 USDT, keeping the pool in a 50–50 balance.
- If the price of ETH rises to 3,000 USDT, traders use the pool to buy cheaper ETH, reducing their ETH share but increasing their USDT share.
- When you withdraw your funds, you might now have 0.8 ETH and 2,400 USDT, which equals 4,800 USDT.
- If you had simply held your 1 ETH and 2,000 USDT, they would now be worth 5,000 USDT.
- The difference of 200 USDT is the impermanent loss you experienced by providing liquidity.
How to Calculate Impermanent Loss?
Calculating impermanent loss helps you estimate how much value you might lose when token prices change. The formula compares the current value of your assets in a liquidity pool with what they would be worth if you had not provided liquidity.
Formula for Impermanent Loss
The formula for estimating impermanent loss is:
Impermanent Loss = 2 × √(price ratio) / (1 + price ratio) – 1 |
Here, the price ratio means the new price of a token divided by its original price when you added it to the pool. This shows how much the token’s value has changed since your deposit.
Factors That Influence Impermanent Loss
Several factors affect how much impermanent loss a liquidity provider might face. Understanding these elements helps you decide where and how to invest your tokens safely in DeFi pools.
Price Volatility
The more prices move up or down, the higher the risk of impermanent loss. When one token in a pair changes in value faster than the other, it creates an imbalance in the pool. Coins with stable prices usually experience smaller losses, while volatile tokens can lead to higher exposure.
Token Pair Selection
The type of tokens you choose greatly influences your risk. Stable pairs like USDC/DAI or BTC/ETH move in similar patterns, so the difference in price remains smaller. Tokens that are less related or more volatile, on the other hand, create larger losses when their prices diverge too much.
Market Activity
High trading volume affects token ratios in a liquidity pool. When many trades happen quickly, the pool rebalances more often, which increases the chances of impermanent loss. However, active markets also generate more trading fees, which can sometimes make up for these losses.
How to Manage Impermanent Loss?
While you cannot completely avoid impermanent loss, you can manage it by using smart strategies. These approaches help reduce the effect of price swings and protect your earnings as a liquidity provider.
Use Stable or Correlated Tokens
Choosing tokens that move in similar price directions helps limit losses. Stablecoins like USDC, DAI, or USDT are good options because their prices do not change much. When paired together, these coins keep the pool balanced and lower the risk of losing value from large price differences.
Choose Reliable AMMs
Always use trusted and well-established Automated Market Makers such as Uniswap, Balancer, or SushiSwap. These platforms have strong liquidity and security, reducing the risk of manipulation. They also tend to have better fee structures, which can help offset any losses from market movements.
Diversify Liquidity Allocation
Avoid putting all your funds into one liquidity pool. Instead, spread your assets across different pools and token pairs. This way, if one pool experiences high volatility, your overall risk remains lower, and other pools can balance out potential losses with more stable returns.
What Is Impermanent Loss Protection (ILP)?
Impermanent Loss Protection, often called ILP, works like insurance for liquidity providers. It protects them from unexpected losses when token prices change after depositing into a pool. This feature helps make DeFi investing safer and encourages more users to participate in liquidity farming.
How Impermanent Loss Protection Works?
Here’s how Impermanent Loss Protection works:
Price Change Detection: The system tracks price movements of the tokens in a liquidity pool. When the prices start to drift apart, ILP calculates the potential loss.
Loss Compensation: If the price gap leads to a real loss, the platform compensates the liquidity provider for the difference between the initial deposit value and the current pool value.
Gradual Coverage: Many DeFi platforms offer coverage that grows over time. The longer you keep your assets in the pool, the greater your protection becomes.
Final Payout: When liquidity providers withdraw their tokens, ILP ensures that their total value includes compensation for any losses incurred due to token price changes.
This structured approach helps maintain investor confidence by reducing the risks of sudden market volatility.
Why ILP Matters for Liquidity Providers?
Here’s why ILP is valuable for liquidity providers:
Increased Confidence: Knowing that potential losses are covered motivates investors to keep their funds in the pool for longer periods.
Balanced Risk and Reward: ILP helps maintain a fair balance by ensuring liquidity providers are rewarded for supporting the market while limiting their downside risk.
Encourages Participation: When investors feel safer, they are more likely to contribute liquidity, improving the overall efficiency and stability of the DeFi ecosystem.
Long-Term Earning Potential: ILP allows providers to earn trading fees and incentives while reducing the chances of suffering large financial setbacks due to market volatility.
This protection system ultimately makes liquidity provision more appealing, sustainable, and profitable for investors across DeFi platforms.
Conclusion
Impermanent loss is one of the main challenges liquidity providers face in the DeFi world. It happens when token prices move differently after being added to a pool, causing a temporary drop in value. However, by using stable or correlated pairs, diversifying across pools, and choosing reliable AMMs, investors can manage this risk effectively.

Frequently Asked Questions
Is Impermanent Loss The Same As Permanent Loss?
No, impermanent loss is temporary and can disappear if token prices return to their original levels. Permanent loss happens only when you withdraw your tokens from the pool before prices recover, locking in the lower value and making the loss final.
How Do Trading Fees Offset Impermanent Loss?
Trading fees earned from each transaction in the pool can help balance out potential losses. If a pool has high trading activity, the accumulated fees may even exceed the impermanent loss, allowing liquidity providers to make an overall profit despite price changes.
Can You Experience Impermanent Loss With Stablecoins?
Yes, but the risk is very low. Stablecoins such as USDC, DAI, or USDT have minimal price fluctuations. Since their values stay close to one another, liquidity providers in stablecoin pairs experience only tiny amounts of impermanent loss compared to volatile token pairs.
Are All Liquidity Pools Equally Risky?
No, risk levels vary depending on the token pair and trading volume. Pools with highly volatile or unrelated tokens are riskier. On the other hand, pools with stable or correlated assets tend to be safer and provide steadier returns through transaction fees and rewards.
How Long Should I Keep My Assets in a Pool?
It depends on your goals and the market conditions. Keeping assets longer can earn more fees and, in some cases, qualify for greater protection like ILP. However, monitoring price movements regularly ensures you avoid major losses during large market swings.
What Happens If I Withdraw During A Period Of Price Volatility?
Withdrawing when prices are highly unstable can turn an impermanent loss into a permanent one. If token prices are far from their original ratio, your withdrawn assets may be worth less than your initial deposit. Waiting for prices to stabilise can reduce this impact.
