How Impermanent Loss Works In Plain Language
Learn how impermanent loss works, when it bites, and how written LP rules beat mood-based rebalancing. Paper first. Keys stay yours.

How impermanent loss works is simple once you strip the jargon: when you provide liquidity to a pool, your share is rebalanced as prices move, so you can end up with a different mix of assets than you deposited, often worth less than if you had just held both. The hard part is not the formula. It is the 1am urge to yank liquidity, chase a peg, or double size because the chart looks unfair. When you need to stop negotiating with yourself on every pool move, Chatito is the system: written rules, paper proof, then live size only when you mean it.
This guide explains the mechanism, the math you actually need, and the process habits that keep liquidity work from turning into another emotion loop. Not financial advice. LP positions can lose money.
How Impermanent Loss Works Step By Step
You deposit two assets into an automated market maker (AMM) pool. Traders swap against that pool. The pool keeps a pricing curve (classic constant product is the usual teaching example: reserves of token A times reserves of token B stay roughly constant, fees aside).
As one asset rises relative to the other, arbitrage and swaps pull the cheaper side out and push the richer side in. Your LP share is a claim on the pool's current mix, not on the exact coins you put in. That drift is the core of how impermanent loss works.
"Impermanent" means the gap is measured against holding the same starting stack outside the pool. If prices return to your entry ratio, that gap can shrink or vanish. If you exit while the ratio is still skewed, the gap becomes a realized shortfall versus hold. Fees and incentives can offset some of it. They do not erase the rebalancing math.
A plain checklist:
- You deposit a value-matched pair (or a range, on concentrated venues).
- Market price moves.
- The pool's inventory shifts toward the asset that underperformed in relative terms.
- Your claim tracks that new mix.
- Compare exit value to "I just held both" to see the IL gap.
DEX liquidity is an example venue here. The job is still the same as anywhere else: run a plan so you stop deciding every candle by mood.
The Hold Baseline You Keep Forgetting
People feel robbed because they compare LP exit value to the moon bag of the winner asset alone. That is the wrong baseline. The honest comparison for classic two-sided IL is hold both assets in the same starting weights, not all-in on the runner.
Rough teaching numbers (rounded, fees ignored):
| Relative price move | Approx. IL vs hold both |
|---|---|
| 1.25x on one side | About 0.6% |
| 1.5x | About 2% |
| 2x | About 5.7% |
| 3x | About 13.4% |
| 5x | About 25.5% |
Small moves barely show up. Large directional moves do. Correlated pairs (think stable-ish vs stable-ish) usually produce less IL than a volatile token paired with a stable. Highly volatile pairs can print big fee numbers and still underperform hold when the chart one-ways.
Concentrated liquidity adds another layer: if price leaves your range, you sit mostly in one asset and stop earning swap fees until you re-enter. That is not a different universe. It is the same rebalancing idea with a hard edge and more decisions to write down in advance.
Fees, Incentives, And The Story You Tell Yourself
Fees accrue when volume hits the pool. Incentives (emissions, points, seasonal programs) are extra. Neither is a promise that net LP beats hold.
Process bugs that show up around IL:
- Fee FOMO: chasing the loudest pool without a rule for pair volatility or exit.
- Range tilt: tightening range after a quiet week, then rage-widening after a wick.
- Harvest addiction: compounding rewards while ignoring that inventory risk is the main story.
- Revenge rebalance: yanking and redepositing because the dashboard looks "unfair," not because a written condition fired.
Write the job in human words: help me run liquidity with a plan so I stop negotiating every pool print. Strategies over emotions is not a poster. It is "I already decided what volatility, range width, fee threshold, and kill condition mean before the candle."
A Small Worked Example
Suppose you deposit $1,000 of ETH and $1,000 of a stable into a simple 50/50 pool. ETH doubles versus the stable while you are in range (classic full-range teaching case).
Outside the pool, hold both would be roughly $2,000 ETH + $1,000 stable = $3,000. Inside the pool, rebalancing leaves you with less ETH and more stables. Your LP claim's mark is higher than $2,000, but short of the $3,000 hold path. That gap is IL versus hold. Swap fees collected along the way reduce the gap. A violent one-way move with thin volume can leave fees too small to care.
If you exit after the double, the loss versus hold is permanent for that episode. If ETH later returns to the entry ratio and you never exited, the IL measure can compress again. That is why the word "impermanent" exists. It is not insurance. It is a reminder that path and exit timing matter.
Write Rules Before You Touch The Pool
You do not need a PhD curve. You need constraints you will still respect when the UI flashes green and red.
Useful rule types (examples, not signals):
| Rule type | What you define in advance |
|---|---|
| Pair filter | Max historical or expected relative vol you will LP |
| Size cap | Max % of liquid net worth in any one pool |
| Range policy | Width, recenter triggers, cool-down between adjusts |
| Fee gate | Minimum fee APR or volume condition to justify inventory risk |
| Time stop | Review cadence; no "just one more day" without a checklist |
| Kill | Hard exit if inventory skew, oracle stress, or drawdown hits X |
Invent and prove process before you scale live size. If the rules only exist in your head, you will renegotiate them the first time IL shows up on a dashboard.
Prove The Book On Paper First
Paper (or a dry simulation journal) is where you test whether your pair filters and range habits survive boring weeks and violent weeks. Track hold-both baseline, fee income, incentive income, and exit value under the same rules you claim you will use live.
What you are sampling is not "will this pool moon." You are sampling whether you can follow the book without mid-course hope trades. Automate once the rules are stable so you stop negotiating with yourself on every candle and every tick of the curve.
Where Process Meets Liquidity Work
DEX LP is one example of inventory risk with a public formula. The same spine applies when you move capital elsewhere: define the edge hypothesis, define failure, size small, prove behavior, then arm.
Paper First On Liquidity Too
Chatito is built for people who want to stop negotiating with themselves when markets get loud. Encode the rules. Sample them. Arm live only when the process holds. Paper first. You arm live. Keys stay yours.

How Impermanent Loss Works When You Exit Early
Exit early relative to mean reversion and you crystallize the gap versus hold. Exit after a round trip with fat fees and you may beat hold. Neither outcome is a personality test. It is path plus rules. If your only plan is "I will feel it," you already hired mood as the portfolio manager.
Run the system, not the dopamine. That means IL is a measured inventory cost inside a written strategy, not a nightly argument.
Short Risk Note
Not financial advice. Providing liquidity, trading, and prediction markets involve risk of loss, including smart contract, oracle, and market risk. Paper results are not live results. Past or simulated performance does not guarantee future outcomes. Never deposit into anything you do not understand. Keys stay yours means self-custody discipline, not a promise of profit.
When you need to stop negotiating with yourself, Chatito is the system. Prove the book. Then decide, on purpose, whether live size still makes sense.

FAQ
- What is impermanent loss in one sentence?
- Impermanent loss is the value gap between holding two assets in a wallet versus holding the same starting deposit as an LP share after the pool rebalances with price moves.
- Is impermanent loss a guaranteed loss?
- No. It is a comparison to a hold-both baseline. Fees and incentives can offset it, prices can revert, and your exit timing changes whether the gap is temporary on paper or realized when you withdraw. Nothing about LP is risk-free.
- Does concentrated liquidity remove how impermanent loss works?
- No. It changes the shape. In range you still rebalance; out of range you often sit in one asset and stop earning swap fees until you reset. You need written range and recenter rules more, not less.
- How do I practice LP rules without gambling size?
- Paper the book first: same pair filters, size caps, fee gates, and kill conditions you would use live. Compare LP mark and fees to hold-both on a schedule. Arm live only when the process holds.
- Where does Chatito fit with liquidity strategies?
- Chatito is a system so you stop deciding every candle by mood. Paper first. You arm live. Keys stay yours. Not signals. Not a vault. Liquidity venues are examples of the same process spine.
Not financial advice. Trading involves risk of loss. Paper ≠ live.
