What Is Impermanent Loss Explained | DeFi

In the fast-evolving world of decentralized finance (DeFi), impermanent loss is a concept that has gained significant attention among liquidity providers. To grasp the intricacies of impermanent loss, let's delve into its definition, mechanisms, and its implications on liquidity pools.

What is Impermanent Loss?

Impermanent loss occurs when providing liquidity to a decentralized exchange or liquidity pool results in a temporary reduction in the overall value of the provided assets. This phenomenon arises due to the dynamic nature of token prices in such environments.

In a traditional market scenario, holding assets means their value is subject to market fluctuations. However, in a liquidity pool, impermanent loss is a consequence of changes in the relative value of the two assets being provided as liquidity.

By providing liquidity too the pools a transaction fee is often earned to help off set this loss. When a person removes their liquidity from a pool this is when the impermanent loss occurs. 

Examples of this will be shown below to help illustrate how this might look with your own investments.

How Does Impermanent Loss Occur?

Impermanent loss is closely tied to the price divergence of the assets within a liquidity pool. When the price of one asset in the pool changes significantly compared to the other, the value of the pool changes.

To illustrate, consider a liquidity provider who deposits equal values of two tokens, A and B, into a pool. If the price of token A rises relative to token B, the automated market maker (AMM) algorithm will rebalance the pool by selling some token A and buying more of token B to maintain a 50/50 value distribution. This action results in the liquidity provider having fewer tokens of the appreciating asset, leading to impermanent loss.

Implications for Liquidity Providers

Liquidity providers face the challenge of balancing potential impermanent loss against the rewards gained from transaction fees. The more volatile the market, the higher the risk of impermanent loss. Traders can capitalize on these fluctuations, but liquidity providers need to carefully weigh the potential loss against the fees earned.

Strategies to Mitigate Impermanent Loss

Several strategies can help liquidity providers mitigate impermanent loss. One approach is to select assets with low volatility or to provide liquidity to pools with more stable asset pairs. This is often done in the cryptocurrency world by pairing a token with what is known as a stablecoin such as USDt, USDC, Dai, TUSD and many others and  Additionally, actively managing the liquidity pool by adjusting the deposited amounts in response to market changes can help minimize losses.

Real-world Examples of Impermanent Loss

To illustrate the concept more vividly, let's explore a few hypothetical examples:

Example 1: Stablecoin Pair

Consider a liquidity provider depositing equal values of two stablecoins, USD Coin (USDC) and Dai (DAI), into a liquidity pool. If the price of USDC increases relative to DAI, the AMM will rebalance by selling USDC and buying more DAI. The liquidity provider will experience impermanent loss due to the change in the composition of their holdings.

Example 2: Volatile Token Pair

Now, imagine a liquidity provider depositing equal values of two highly volatile tokens, TokenX and TokenY. If TokenX experiences a sudden surge in price, the AMM will rebalance the pool by selling TokenX and acquiring more TokenY. The liquidity provider will incur impermanent loss as their holdings shift in response to the price dynamics.

Example: Impermanent Loss Resulting in Loss of Value

  1. Initial Deposit:
    • A liquidity provider deposits $1,000 worth of Token A and $1,000 worth of Token B into a liquidity pool.
    • Total Value of the Liquidity Pool = $2,000.
  2. Price Change:
    • Subsequently, the price of Token A decreases by 30%, while the price of Token B remains the same.
    • The new price of Token A is $0.70 (initially $1.00).
  3. Rebalancing:
    • The automated market maker (AMM) algorithm detects the price change and rebalances the pool to maintain the 50/50 ratio.
    • The AMM sells $150 worth of Token A (30% of $500, the decrease in value) and buys more Token B.
  4. New Composition of Holdings:
    • Before the price change, the liquidity provider had $1,000 worth of each token.
    • After the rebalancing, the liquidity provider now has $850 worth of Token A ($1,000 - $150) and $1,150 worth of Token B ($1,000 + $150).
  5. Impermanent Loss Calculation:
    • Impermanent Loss = (Value of Original Holdings) - (Value of Current Holdings)
    • Impermanent Loss = ($1,000 + $1,000) - ($850 + $1,150)
    • Impermanent Loss = $2,000 - $2,000
    • Impermanent Loss = $0


In this example, despite the decrease in the price of Token A, the liquidity provider experiences impermanent loss that is offset by the rebalancing mechanism. The resulting composition of holdings still has the same value as the initial deposit. It's worth noting that impermanent loss doesn't always lead to a net loss; the outcome depends on the interplay between price changes, the rebalancing process, and the overall market conditions.

Impermanent loss is a crucial consideration for liquidity providers in the DeFi space. Understanding its mechanics and implementing strategies to mitigate its impact is essential for those engaging in liquidity provision. As the DeFi ecosystem continues to evolve, staying informed about such concepts is paramount for navigating the decentralized financial landscape successfully.
