Impermanent Loss in Concentrated Liquidity

Impermanent loss (IL) is one of the most important concepts for any liquidity provider to understand. In concentrated liquidity pools, IL behaves differently — and more intensely — than in traditional full-range AMMs. This page explains what IL is, how CL changes its mechanics, and how to manage the tradeoff between fees and IL risk.

What is impermanent loss?

When you deposit two assets into an AMM as a liquidity provider, the pool's rebalancing mechanism automatically buys and sells those assets as prices move. This means that whenever one asset appreciates against the other, the pool sells some of the appreciating asset to maintain balance — and you end up holding less of it than if you had simply held both assets in a wallet.

Impermanent loss is the difference in value between:

What your position is worth after the price moves, and
What you would have if you had held the same assets without providing liquidity.

The "impermanent" label reflects the fact that the loss only materialises if you withdraw while prices are diverged. If prices return to the level at which you entered, IL effectively disappears. However, in practice many LPs do withdraw when prices have moved — so it is a real economic cost to factor in.

The primary driver of IL is price divergence: the more an asset's price moves away from the entry price, the larger the IL. Fees earned while providing liquidity offset IL to varying degrees, which is why the fee-vs-IL tradeoff is central to LP strategy.

How concentrated liquidity amplifies IL

In a traditional full-range AMM, your liquidity is spread across the entire price curve — from zero to infinity. In a concentrated liquidity pool, you deploy capital into a specific price band. This is what makes CL so capital-efficient, but it is also what makes IL more severe within that band.

The amplification principle: a narrower price range means your capital is doing more work per dollar — but it also means a given price movement consumes a larger fraction of your range. The same price move that causes modest IL in a full-range position causes proportionally larger IL in a concentrated position.

To put it concretely:

Full-range LP on ETH/USDC: a 10% price increase causes a small, well-spread IL because your liquidity covers the full curve.
Concentrated LP on ETH/USDC in a ±5% band: a 10% price increase takes the price fully outside your range — with more severe consequence (see below).
Narrower CL range (e.g. ±2%): the same 10% move is even more severe relative to the range width.

This is the fundamental tension in CL: narrower ranges earn higher fees per dollar of capital, but they amplify IL and go out of range more often.

Going out of range — the defining CL behaviour

Going out of range is a uniquely CL concept with direct economic consequences.

When the market price exits your selected band, your position stops earning fees immediately. The pool no longer uses your capital for trading, so you receive no compensation from swap activity while you are out of range.

At the same time, the pool has already rebalanced your position into a single asset:

Price rises above the upper bound of your range: your position has been fully converted into the quote asset (e.g. USDC in an ETH/USDC pair). The pool sold all of your ETH on the way up as price moved through your range — you have already realised the loss of the appreciating asset.
Price falls below the lower bound of your range: your position has been fully converted into the base/volatile asset (e.g. ETH). The pool bought ETH with all your USDC on the way down, and you now hold only the depreciating asset.

In both cases, the loss is effectively locked in for as long as you remain out of range. You earn no fees to compensate, and you are left holding the less favourable asset. This is the worst-case outcome for a concentrated liquidity position.

Out-of-range positions earn zero fees. If the price does not return to your band, your only options are to withdraw at a loss, or actively rebalance your range to follow the market.

Worked example: ETH/USDC in a $1,900–$2,100 range

This example builds on the scenario described in the Concentrated Liquidity overview.

Suppose you provide liquidity in an ETH/USDC pool with your range set to $1,900–$2,100, with ETH currently at $2,000.

Scenario A — price rises to $2,300:

As ETH climbs from $2,000 toward $2,100, the pool progressively sells your ETH for USDC through your range.
At $2,100 your position is 100% USDC — you have sold all your ETH.
ETH continues to $2,300, but you no longer participate. You hold only USDC.
Your position is out of range: zero fees earned, and you missed the additional $200 of ETH appreciation.
The IL here is the difference between holding ETH+USDC through the rise versus what the pool left you with.

Scenario B — price falls to $1,700:

As ETH falls from $2,000 toward $1,900, the pool buys ETH with your USDC through your range.
At $1,900 your position is 100% ETH — all USDC has been spent buying a falling asset.
ETH continues to $1,700. You hold only ETH, now worth less.
Your position is out of range: zero fees earned, and you absorbed the full decline with leveraged exposure to ETH.

If price returns to $2,000: in both scenarios, IL partially or fully reverses as the price re-enters your range and the pool rebalances back toward a mix of both assets. This is why the loss is described as "impermanent."

The IL-vs-fees tradeoff

The fee revenue a position generates while in range is the primary mechanism offsetting IL. Understanding the tradeoff is the core skill for CL liquidity management.

Range preset	Range width	Fee earning rate	Out-of-range frequency	IL amplification
Full range	Infinite	Lowest (diluted)	Rarely or never	Lowest
Safe	Wide (e.g. ±15–20%)	Moderate	Infrequent	Moderate
Common	Medium (e.g. ±5–10%)	Higher	Moderate	Higher
Expert	Narrow (e.g. ±1–3%)	Highest	Frequent	Highest

These presets correspond to the options described in Manual Ranges:

Full range: Provides liquidity across the entire price spectrum. The lowest fee concentration, but also the lowest IL amplification and essentially no out-of-range risk. Best suited to passive LPs who prefer simplicity over maximum returns.
Safe range: A broader band aimed at lower risk. Offers a solid balance of uptime and fee generation without frequent rebalancing.
Common range: Targets a frequently traded price area with a balance of fee generation and manageable out-of-range risk.
Expert range: Narrowest band, highest fee density per dollar, but highest IL and the most frequent out-of-range events. Requires active monitoring and rebalancing.

Higher fee rates from a narrow range only benefit you while the position is in range. A position that earns 3x the fees but spends 80% of its time out of range may underperform a wider, lower-fee position. Uptime matters.

Managing and mitigating IL

There is no way to eliminate IL in a volatile pair — it is a structural property of how AMMs work. However, several strategies reduce its impact:

Choose an appropriate range width. Wider ranges go out of range less often and keep capital earning fees more consistently. Match the range width to your ability and willingness to monitor and rebalance.
Prefer correlated or stable pairs. IL is driven by price divergence. When both assets in a pair move similarly (e.g. two stablecoins, or two liquid staking tokens tracking the same underlying), divergence is limited and IL is naturally reduced. See Classic Liquidity for Orvex's stable pool option.
Rebalance actively. When price moves outside your range, you can withdraw, reset your range around the new price, and re-enter. This turns "locked-in" IL into a fresh position — though it costs gas and time, and crystallises the loss at that moment.
Let fees accrue over time. Swap fees accumulate while the position is in range. For a well-placed, consistently in-range position on a high-volume pair, fees can substantially offset or exceed IL over time. On Orvex, gauge oORVX emissions provide an additional return stream for staked LP positions, which contributes further to offsetting IL — though the magnitude depends on pool weight and current emission rates, which vary.
Consider full-range for passive strategies. If active management is not your goal, a full-range or very wide range position on Classic Liquidity pools eliminates out-of-range risk entirely, at the cost of lower fee concentration.

For most passive LPs in volatile pairs, starting with a Safe or Common range preset (see Manual Ranges) provides a better balance of fee uptime and IL risk than Expert or full-range extremes.

Key takeaway

Concentrated liquidity amplifies both the upside (fees) and the downside (IL) of providing liquidity. The narrower your range, the harder your capital works — and the more exposed you are when price moves beyond your band. Out-of-range positions earn zero fees and hold a single asset, making active range management essential for narrow positions. Choose your range width according to how actively you intend to manage your position, and factor in fees and any additional gauge emissions as the offset against IL.
