Concentrated Liquidity: Choosing a Price Range That Survives Volatility

Why concentrated liquidity providers earn far more than passive ones, and the single range decision that determines whether they keep it. The mechanism rewards precision and punishes ranges that drift outside the market.

How a concentrated position differs

A passive pool holds an equal value of both assets across all prices and charges a flat fee. Its liquidity is always available, so the fee tier has to stay low.

A concentrated position places liquidity inside a chosen price band. Inside the band it behaves like a normal pool, out of the band it earns nothing at all. For the same dollar of capital, the fee tier can be several times higher because capital is used far more efficiently.

The trade is direct. Concentration multiplies fee income and multiplies the cost of being wrong about the range.

Why fees accumulate when price stays inside

Fees accrue only while swaps pass through the price you supplied. If the market trades inside your band every day, your capital is working continuously, and the higher fee tier is justified.

If the market drifts to your lower bound and sits there, the position converts gradually into one asset and stops earning. That is the outcome most providers underestimate.

• Price above your upper bound: the position has fully converted into the asset you were selling into.
• Price below your lower bound: it has fully converted into the other asset, with nothing left to sell.
• Either state means the position is idle until you rebalance.

Rebalancing costs more than the fee tier suggests

Moving back into range means swapping part of the position back toward the balance it started with. That swap pays fee, pays price impact, and pays slippage on whatever depth exists at that moment.

If the range is narrow, those rebalances are frequent. If the range is wide, they are rare but the fee tier cannot be set as high. There is no setting that solves both.

A reasonable approach is a wide range and a moderate fee tier for capital you want to leave untouched, and a narrower range only where you are actively watching the position and can rebalance without panic.

Active management changes the risk profile

A range that would be reckless as a passive position can be reasonable as a managed one, because the exit is decided in advance rather than during a crash.

Three decisions have to be made before the position is opened:

• The rebalancing level, which is a rule you follow rather than a judgement you make under stress.
• The maximum loss you accept while out of range, expressed as a percentage of the deposited value.
• The condition under which you close, such as a sustained break outside the band or a fee income target.

Without those rules, the position is an unmanaged directional bet with a fee attached, and the fees are too small to compensate for a large move in either asset.

What the fee tier does and does not tell you

The tier is a commitment about volatility. A high tier assumes the pair will stay within a narrow band, and it earns well exactly when that assumption holds.

Fees are also shared across the whole range of all providers at that tier, so the tier alone says nothing about how much of the available flow you capture. Two identical positions at the same tier earn the same fee share regardless of which one was opened first.

Volume does not mean profit. A position in a pair with frequent swaps and thin depth can earn a high nominal fee while paying more in slippage and rebalance costs than it collects.

Frequently asked questions

What happens when the price leaves my range?

The position stops earning and begins converting one-sidedly, and it stays in that state until you rebalance. Nothing is lost mechanically; the fee income simply stops.

Is a narrow range always better?

No. A narrow range earns more per unit of capital while the price stays inside and drains into slippage and rebalance cost when it does not. Depth matters as much as the fee tier.

How often should I rebalance?

Often enough to keep fees accruing, and rarely enough that the cost stays below the income. That balance depends on volatility, and it is a judgement call rather than a fixed interval.
