Impermanent Loss Explained

This lesson explains why liquidity providers can lose money—even when prices go up.

Part 1: The Core Idea

Impermanent Loss (IL)

Impermanent Loss is the difference between:

• Holding your tokens

vs

• Providing them as liquidity

Key Insight

Part 2: Why Impermanent Loss Happens

AMM Formula

What This Means

The pool must always stay balanced.

What Happens When Price Changes

Example:

ETH price goes up.

Traders buy ETH from the pool.

As a result:

• The pool loses ETH

• The pool gains USDC

Result

You now hold:

• Less ETH

• More USDC

Key Insight

Part 3: The Real Problem

If You Simply Held ETH

ETH increases → You profit fully.

If You Provide Liquidity

ETH increases → The pool continuously sells part of your ETH.

Result

You make less profit compared to simply holding.

Part 4: Simple Example

Starting Position

1 ETH = $1000

You deposit:

• 1 ETH

• $1000 USDC

ETH Price Doubles

ETH = $2000

If You Held

• 1 ETH = $2000

• $1000 USDC

Total = $3000

If You Provide Liquidity

You now hold approximately:

• 0.707 ETH

• $1414 USDC

Total ≈ $2828

Impermanent Loss

Approximate difference:

• ~$172 less than simply holding

Key Insight

Part 5: Why It’s Called “Impermanent”

It Becomes Permanent When

• You withdraw from the pool

It Can Disappear If

• Price returns to the original level

Reality

Prices rarely return perfectly to the original ratio.

Operator Insight

Most impermanent loss eventually becomes permanent.

Part 6: When Impermanent Loss Is Worst

High-Risk Situations

• Volatile token pairs (ETH/ALT)

• One token rapidly increases in price

• Low liquidity pools

Key Insight

Part 7: When Impermanent Loss Is Lower

Safer Scenarios

• Stablecoin pairs (USDC/DAI)

• Correlated assets

Examples

• ETH / stETH

• USDC / USDT

Why These Are Safer

Part 8: Fees vs. Impermanent Loss

The Real Tradeoff

As an LP:

• You earn trading fees

• You lose value from impermanent loss

Profit Condition

Fees earned must be greater than impermanent loss.

Key Insight

Part 9: Hidden Trap (Beginner Mistake)

The Mistake

“High APY means good opportunity.”

Reality

High APY often means:

• High volatility

• High impermanent loss risk

Key Insight

Part 10: How to Reduce Impermanent Loss

Strategies

• Use stablecoin pools

• Use correlated assets

• Choose high-volume pools

• Enter when volatility is low

• Exit when trends become strong

Operator Rule

Part 11: LP vs. Holding Decision

Ask Yourself

“Do I want to hold this asset long term?”

If yes, LP may reduce your upside.

Another Important Question

“Do I prefer yield instead of maximum price exposure?”

If yes, LP may make sense.

Key Insight

Part 12: Mental Model

Think of liquidity providing as running a small exchange.

You:

• Provide liquidity

• Earn fees

• Take inventory risk

Important Reality

LP is not truly passive income.

It is market making with risk.

Practice Mission

Pick a liquidity pool, such as one on Uniswap.

Analyze:

• Token pair

• Volatility

• Trading volume

Challenge

Ask yourself:

“If one token doubles in price, what happens to me?”

Then analyze:

• How your token balance changes

• How much upside you lose

• Whether fees compensate for the risk
