Warlands Academy: What are impermanent losses?

Impermanent loss is a term used in the context of automated market makers (AMMs) in decentralized finance (DeFi) that refers to the temporary loss of value experienced by liquidity providers due to fluctuations in the prices of the assets they have provided liquidity for.

In AMMs, liquidity providers deposit equal values of two different assets into a liquidity pool, which is used to facilitate trades. The price of each asset is determined by the balance of the two assets in the pool. When the price of one asset increases relative to the other, traders will buy the cheaper asset and sell the more expensive one, which causes the balance of the assets in the pool to shift, and the price of each asset to adjust accordingly.

This price adjustment creates a temporary loss for liquidity providers who will receive fewer units of the asset that increased in price when they withdraw their liquidity from the pool. However, if the price of the assets returns to its original level, the liquidity provider will eventually recoup the loss.

In summary, impermanent loss refers to the temporary reduction in the value of a liquidity provider’s deposit in a decentralized exchange, resulting from changes in the price of the assets in the liquidity pool.

Why are impermanent losses important?

Impermanent losses are important for several reasons in decentralized finance (DeFi):

1.  Liquidity providers who deposit assets into a liquidity pool face the risk of impermanent losses due to price fluctuations. It’s essential for them to understand this risk before depositing their assets into the pool.
2.  Impermanent losses can incentivize liquidity providers to deposit their assets into the pool, as they receive trading fees from users who trade against their assets. These fees can offset the potential impermanent loss.
3.  Impermanent losses can impact the trading fees paid by traders. Since the price of the assets in the pool can change rapidly, traders may end up paying higher trading fees due to the resulting slippage.
4.  The potential for impermanent losses can impact the depth of liquidity available in a liquidity pool. Liquidity providers may be hesitant to deposit their assets if they perceive the risk of impermanent losses to be too high, which can lead to shallower pools and lower liquidity.

Overall, impermanent losses are an important consideration for liquidity providers and traders in decentralized exchanges, and understanding their potential impact is critical to successful participation in the DeFi ecosystem.
