Concentrated Liquidity: Uniswap v3 Ranges Explained

Key Takeaways

• Concentrated liquidity lets providers supply capital only within a chosen price range.
• Inside the range, capital efficiency rises sharply versus spreading it across all prices.
• A position earns no fees and sits in one asset once price leaves the range.
• The price space is split into ticks, each a step of 0.01 percent in price.

What It Is

Concentrated liquidity is the core innovation of Uniswap v3, launched in May 2021. In earlier constant-product pools, a provider's capital was spread evenly across every possible price from zero to infinity. Most of that capital sat idle at prices the asset would likely never reach.

Uniswap v3 lets a provider pick a price range and put all their capital to work only inside it. Within the chosen range, the position behaves like a constant-product pool but with much greater depth for the capital committed. That depth is what raises fee income per dollar.

The Intuition

Think about an asset that mostly trades between 1,800 and 2,200 in price. In an old-style pool, your capital also backs prices like 100 or 10,000 that almost never occur. That is wasted depth.

Concentrating liquidity moves that idle capital into the band where trading actually happens. The trade-off is that the position only earns fees while the market price stays inside your range. Step outside it and your capital converts entirely into the cheaper asset and stops earning. Concentrated liquidity turns a passive deposit into an active position that resembles a market maker quoting a band, with the returns and the risks that implies.

How Concentrated Liquidity Uniswap v3 Pools Work

The price space is divided into discrete points called ticks. Each tick is a fixed step in price:

price at tick i = 1.0001 ^ i

So moving one tick up multiplies the price by 1.0001, a step of 0.01 percent. A position is defined by a lower tick and an upper tick, which set the range boundaries. Inside the range the math uses virtual reserves: the contract simulates a constant-product curve x * y = k but only for the slice between your two ticks, which is why the effective depth is higher than the real capital alone would provide.

Your position is summarized by a single value L, the liquidity, which measures the depth your capital adds across the range. While price is inside the range, you hold a mix of both tokens and collect a share of swap fees. As price moves up through the range, the position automatically sells one token for the other. When price crosses your upper tick, you hold 100 percent of the lower-value token and earn nothing until price returns. The same happens in reverse below the lower tick.

Because positions are no longer identical, a provider's stake is recorded as a non-fungible token rather than a fungible pool token. Each position has its own range and its own accrued fees, so it cannot be pooled with everyone else's the way an earlier full-range deposit could. That is a structural change: managing liquidity becomes managing individual positions, and tooling has grown up around automating the rebalancing that tight ranges demand.

Worked Example

Suppose ETH trades at 2,000 and you provide liquidity in a range from 1,900 to 2,100. You deposit a mix of ETH and a stablecoin sized to that band.

While ETH stays between 1,900 and 2,100, your capital is concentrated in that band, so it provides far more depth than the same money spread across all prices. You earn a larger share of swap fees as traders pass through your range. A provider who spread the identical capital from zero to infinity would earn a small fraction of those fees, because their depth at 2,000 would be thin.

Now ETH rallies to 2,150, above your upper tick. The position has sold all its ETH for the stablecoin along the way, so you now hold only the stablecoin and earn no fees. If ETH falls back into the range, fee earning resumes. If it keeps rising, you are fully out of ETH and miss the upside, the active-management cost of a tight range.

Common Mistakes

1. Setting a range too tight without monitoring. A narrow band earns high fees while price stays inside, but price leaves it quickly. Once out of range, the position earns nothing and sits in one asset. Tight ranges demand active rebalancing.

2. Underestimating impermanent loss. Concentrating liquidity amplifies impermanent loss within the range. The higher fee income must be weighed against larger divergence loss, not assumed to be free yield.

3. Forgetting gas costs of rebalancing. Moving a range as price drifts costs gas each time. For small positions, those costs can eat the extra fee income that concentration was meant to capture.

4. Treating a v3 position like a passive deposit. Unlike a full-range pool, a concentrated position can stop working entirely. It needs attention, especially in volatile markets.

5. Ignoring that out-of-range capital is fully converted. When price exits the range, you are left holding the asset that fell relative to the other. That is a realized shift in your holdings, not a temporary state, unless price returns.

Frequently Asked Questions

What is concentrated liquidity Uniswap v3 in simple terms? Concentrated liquidity Uniswap v3 lets a provider supply capital only within a price range they choose. Inside that range the capital works harder and earns more fees, but it earns nothing once price moves outside.

How does concentrated liquidity affect investment decisions? It raises potential fee income for the same capital, which is attractive, but it turns a passive deposit into an active position that needs rebalancing. You should weigh the higher fees against gas costs and larger impermanent loss before choosing a tight range.

What is a real-world example of concentrated liquidity? A provider supplying ETH and a stablecoin only between prices of 1,900 and 2,100 is a typical case. They earn outsized fees while ETH trades in that band and stop earning if it breaks out.

How can investors use concentrated liquidity effectively? Pick a range wide enough to stay relevant given the asset's volatility, monitor the position, and account for gas costs before rebalancing frequently. Wider ranges trade some fee income for less maintenance.

How is concentrated liquidity different from a constant-product AMM? A constant-product AMM spreads capital across all prices, so depth at the current price is thin and management is passive. Concentrated liquidity packs capital into a chosen band for greater depth and fees, but requires active management and stops earning out of range.
