Impermanent loss is a major risk for liquidity providers in decentralized finance (DeFi). Learn what it is, how it affects your returns, and strategies to minimize it.
Table of Contents
In decentralized finance (DeFi), opportunities for profit abound, but risks like impermanent loss are equally notorious. This concept is critical for liquidity providers (LPs) who want to contribute to liquidity pools and earn passive income. Understanding what impermanent loss is, how it affects your returns, and ways to mitigate it are essential skills for any successful DeFi investor.
In this article, we will dive deep into the concept of impermanent loss, how it occurs, how to calculate it, and most importantly, how to minimize its effects.

What is Impermanent Loss?
Understanding Price Volatility and Liquidity Pools
To understand impermanent loss, you first need to grasp how price volatility and liquidity pools work. In the DeFi world, investors provide funds to liquidity pools, which facilitate transactions between different token pairs. Unlike centralized exchanges that have order books, decentralized exchanges (DEXs) such as Uniswap and Sushiswap rely on automated market makers (AMMs). These AMMs use liquidity pools to provide seamless swaps for users. To explore liquidity pools more, check out our article on Liquidity Pools in DeFi.
Liquidity pools consist of pairs of tokens that LPs add to help facilitate trading. For instance, a pool may have ETH/USDT tokens, allowing traders to exchange ETH for USDT or vice versa. The value of these tokens is subject to price volatility, meaning their value can change drastically in a short time, which directly impacts the liquidity pool.
How Impermanent Loss Occurs for Liquidity Providers
Impermanent loss occurs when the price of the tokens in a liquidity pool changes relative to the time you added them. When this happens, the AMM’s algorithm continuously adjusts the quantity of each token in the pool to maintain the ratio between the two tokens. This results in either buying more of the falling asset or selling the rising one to maintain balance.
Let’s look at an example:
- Imagine you contribute 1 ETH and 1000 USDT to an ETH/USDT liquidity pool, with the price of ETH at 1000 USDT. Over time, the cost of ETH rises to 1500 USDT. To keep the pool balanced, the AMM adjusts the ratio, reducing your ETH in favor of USDT.
- If you withdraw your funds now, you will end up with less ETH and more USDT than you initially deposited. The value of your total holdings is now less than what they would have been if you had held the ETH and USDT outside the pool.
- This difference in value is called impermanent loss. The loss is only permanent if you withdraw your funds, hence the term “impermanent.”
How to Calculate Impermanent Loss
Calculating impermanent loss can be complex, but understanding the mechanics is crucial to making better decisions about providing liquidity. The formula used to determine impermanent loss involves the ratio between the current price and the initial price of assets deposited.
Example of Impermanent Loss with Different Token Prices
Consider a scenario where you add 1 ETH (valued at 1000 USDT) and 1000 USDT to a pool:
- If the price of ETH rises to 1500 USDT, you now have approximately 0.7746 ETH and 1162.8 USDT.
- If you had held instead, you would have 1 ETH and 1000 USDT, equivalent to 2500 USDT.
- With the liquidity pool, however, you end up with a combined value of 2324.7 USDT, which is 7% less.
This 7% loss is the impermanent loss due to the change in price ratio between ETH and USDT.
Comparing Loss in Liquidity Pools vs. Direct Token Holding
Comparing the results of providing liquidity versus simply holding the assets helps in understanding the impact of impermanent loss. Holding assets keeps you fully exposed to their price appreciation or depreciation without directly dealing with the effects of AMM algorithms. Learn more about Staking in DeFi to understand the differences between staking and liquidity providing.
In our previous example, had you held ETH and USDT directly, would your total asset value have been higher compared to having them in a liquidity pool with price changes? The risk that LPs face when adding liquidity, especially during volatile periods, becomes evident in these situations.
On the other hand, LPs receive transaction fees from trades that occur in the pool, which can partially or wholly offset the impermanent loss. For this reason, understanding strategies to minimize impermanent loss becomes essential to maintaining profitable returns.
Strategies to Minimize Impermanent Loss
Providing Liquidity to Stablecoin Pools
One effective strategy for minimizing impermanent loss is to provide liquidity to stablecoin pools. Stablecoins like USDC, DAI, and USDT are pegged to fiat currencies, which keeps their volatility very low. As a result, LPs in stablecoin pools are less exposed to drastic price swings, minimizing impermanent loss. For more information on managing risk, consider our article on the Risks of Investing in DeFi.
Examples of stablecoin pools include USDC/DAI and USDT/USDC on platforms like Curve Finance and Balancer. These pools offer safer yields for those who wish to avoid impermanent loss in highly volatile markets.
Choosing Less Volatile Pairs
Another strategy to minimize impermanent loss is choosing less volatile token pairs. For instance, token pairs that are highly correlated or have similar price movements (like ETH/WETH or BTC/renBTC) tend to experience less drastic changes in their ratios, resulting in lower impermanent loss. When assets move similarly, the AMM does not need to adjust quantities as drastically.
This correlation allows LPs to mitigate the risk of having their returns impacted by significant price differences, keeping the pool balanced without major loss. To learn about lending options in DeFi, see our article on Lending and Borrowing in DeFi.
Using Liquidity Pools with Lower Volatility
Platforms like Curve Finance have built their models specifically for low-volatility assets. Their focus on stablecoins and correlated assets helps mitigate impermanent loss significantly. By using pools that include assets like USDC, DAI, and GUSD, LPs can generate yields from fees without the concern of significant impermanent loss.
Another example is Balancer, which allows for weighted pools with custom ratios. You could, for example, provide 80% ETH and 20% USDC, which can help limit exposure to asset price changes and, consequently, impermanent loss.
Platforms with Tools to Manage Impermanent Loss
Uniswap V3's Concentrated Liquidity
Uniswap V3 introduced a new concept called concentrated liquidity, which allows LPs to provide liquidity within specific price ranges. Instead of distributing liquidity across the entire price spectrum, LPs can now choose particular price bands where they expect most trades to happen.
This approach increases capital efficiency and can provide higher yields. It also enables LPs to focus their liquidity in ranges where they can minimize impermanent loss, especially if they believe the price of tokens will stay within the chosen range.

Balancer's Flexible Pool Options
Balancer provides flexible pool options that allow LPs to determine different weight ratios between tokens. Unlike the standard 50:50 pools, Balancer pools can have custom ratios like 80:20 or 60:40, enabling more flexibility and better risk management for LPs.
With weighted pools, LPs can focus on providing more liquidity to the less volatile token, thereby reducing their exposure to price volatility and impermanent loss. LPs can use the diversity of assets and weightings in Balancer to develop sophisticated impermanent loss management strategies, which they can customize to fit their risk appetite.

Bancor's Impermanent Loss Protection
Bancor has a unique system designed specifically to address impermanent loss by providing LPs with insurance. With Bancor’s Impermanent Loss Protection, LPs start receiving partial protection from day one, which grows over time. After 100 days, the protection becomes 100%, meaning LPs can withdraw their liquidity without suffering any impermanent loss.
Another benefit is that Bancor allows single-sided liquidity, meaning that LPs do not have to contribute two tokens to a pool. They can deposit just one token, and Bancor takes care of the other side, reducing complexity and exposure.
