Impermanent loss explained

Understanding Impermanent Loss in Cryptocurrency Trading

Welcome to the world of Decentralized Finance (DeFi)! You’ve likely heard about opportunities to earn rewards by providing Liquidity to Decentralized Exchanges (DEXs). But there’s a risk involved called “Impermanent Loss”. This guide will break down what it is, how it happens, and how you can minimize it. This guide assumes you have a basic understanding of Cryptocurrency and Wallets.

What is Impermanent Loss?

Impermanent Loss (IL) isn’t actually a “loss” in the traditional sense, at least not immediately. It's the *difference* between holding your crypto and providing it to a liquidity pool. It happens when the price of your deposited tokens changes compared to when you deposited them. The bigger the price difference, the bigger the impermanent loss.

Think of it this way: you believe Bitcoin will stay around $30,000. You deposit Bitcoin (BTC) and Ether (ETH) into a liquidity pool on a DEX like Uniswap or PancakeSwap. If the price of BTC goes up to $40,000 while it’s in the pool, you've missed out on potential gains. The DEX uses an algorithm to keep the pool balanced, and to do that, it essentially “sells” some of your BTC to buy ETH. When you withdraw, you'll have less BTC (and more ETH) than if you’d just held them in your Crypto Wallet.

The name “impermanent” comes from the fact that the loss isn’t realized until you withdraw your liquidity. If the prices revert to what they were when you deposited, the loss disappears.

How Does It Work? A Simple Example

Let’s say you deposit $500 worth of BTC and $500 worth of ETH into a liquidity pool, with both tokens trading at $30,000 and $2,000 respectively. This means you deposit 0.01667 BTC and 250 ETH.

The pool is designed to maintain a 50/50 value ratio. Now, let's assume the price of BTC doubles to $60,000, while ETH stays at $2,000.

• **Arbitrage Traders:** Traders will notice the price difference between the DEX and other exchanges. They’ll buy BTC on the DEX (where it’s cheaper due to the pool's mechanism) and sell it elsewhere for a profit.
• **Pool Rebalancing:** This trading action changes the ratio of BTC and ETH in the pool. To maintain the 50/50 value, the DEX will sell some of your BTC and buy ETH.
• **Your Outcome:** When you withdraw, you'll have fewer BTC (perhaps 0.0125 BTC) and more ETH (perhaps 287.5 ETH). The value of your holdings might still be around $1000 total, but you lost out on the full gains from the BTC increase. You would have had $1000 worth of BTC if you had simply held.

This difference in value is the Impermanent Loss.

Permanent vs. Impermanent Loss

It's crucial to understand the difference:

• **Impermanent Loss:** Exists as long as the price ratio between the tokens in the pool changes. It's unrealized until you withdraw.
• **Permanent Loss:** Occurs when you withdraw your liquidity, and the price ratio has changed. The difference between what you have now and what you would have had if you just held the tokens is the permanent loss.

Comparing Holding vs. Liquidity Providing

Here's a table illustrating potential outcomes:

Scenario	Holding Only	Liquidity Providing (IL)
Initial Investment	$1000 BTC + $1000 ETH	$1000 BTC + $1000 ETH
BTC Price Doubles (ETH Stays Same)	$2000 BTC + $1000 ETH = $3000	~$2500 (Due to IL)
BTC Price Halves (ETH Stays Same)	$500 BTC + $1000 ETH = $1500	~$750 (Due to IL)

Factors Affecting Impermanent Loss

• **Volatility:** The more volatile the tokens, the higher the risk of IL. Stablecoin pairs (like USDT/USDC) have very low IL.
• **Pool Ratio:** Pools with a higher proportion of volatile assets are more susceptible to IL.
• **Fees Earned:** Liquidity providers earn fees from trades happening in the pool. These fees can sometimes offset the impermanent loss, but not always. Yield Farming is the process of earning rewards this way.
• **Token Selection:** Choosing tokens you believe will perform well together can minimize IL.

Strategies to Minimize Impermanent Loss

Here are some strategies to consider:

• **Provide Liquidity to Stablecoin Pairs:** Pairs like USDT/USDC have minimal price fluctuations, reducing IL.
• **Choose Correlated Assets:** If you believe two tokens will move in the same direction (e.g., two Layer-2 scaling solutions), IL will be lower.
• **Consider Pools with Lower Volatility:** Research pools before depositing liquidity.
• **Monitor Your Positions:** Regularly check the value of your liquidity and consider withdrawing if IL becomes too significant.
• **Diversify:** Don't put all your eggs in one basket. Spread your liquidity across multiple pools.

Practical Steps to Get Started (and Assess Risk)

1. **Choose a DEX:** Popular options include Uniswap, PancakeSwap, and SushiSwap. 2. **Select a Pool:** Look for pools with reasonable trading volume and acceptable risk. Checking Trading Volume is essential. 3. **Connect Your Wallet:** Connect your MetaMask or other compatible wallet to the DEX. 4. **Deposit Liquidity:** Provide an equal value of both tokens in the pair. 5. **Monitor Your Position:** Use tools like APY.Vision or the DEX’s interface to track your IL.

Conclusion

Impermanent Loss is a complex but crucial concept to understand before participating in DeFi. While it can reduce your potential gains, it doesn’t necessarily mean you’ll lose money. By understanding the risks and implementing strategies to minimize IL, you can make informed decisions and navigate the world of liquidity providing with more confidence.
