Who provides the liquidity — and for how long

Liquidity has owners. How few they are and what holds them decides whether it is still there under stress.

This lesson has had no expert review. It was written for this platform and against the evidence it cites; nobody has gone through it independently.

Learning objectives

  • You can measure the concentration of liquidity providers and put it into context.
  • You can recognize which liquidity is tied to a distribution.
  • You can ask the migration question before it happens.

Check your prior knowledge

Answer these for yourself before reading on. Wherever you hesitate is where this lesson pays off.

Core concept

Fact

Concentration is the real depth question

A pool's depth is a sum over contributions, and those contributions have owners. If the largest three addresses hold two thirds of the depth, the pool is as deep as those three are patient. The number measuring this is not depth but the share of the largest contributors — readable from the pool's balance data, not from the price display.

Interpretation

Rented liquidity is recognized by its reason

Liquidity that is present because of a distribution stays as long as the distribution runs and nowhere pays more. Liquidity present because of trading fees stays as long as there is trading. The difference is readable from the split of the quoted return: a pool whose return is mostly incentives has mostly rented liquidity.

Risk

Migration is the normal case, not the exception

Liquidity migrates to wherever pays most, and switching costs providers little. For a position this matters: the depth an exit calculation rests on can be somewhere else within days. So assessing a pool involves not only its depth today but the question of what holds the liquidity here when more is offered elsewhere.

Assessment

Two numbers that say something together

Concentration says how many decisions are needed to halve the depth. The incentive share says how likely those decisions are in the foreseeable future. Together they give a usable assessment; separately the first is a snapshot and the second a guess about motives.

Definitions

Liquidity provider in the glossary
Someone contributing assets to a pool so others can trade against them.
Rented liquidity
Provided capital whose return comes mostly from a time-limited distribution.
Liquidity migration
The relocation of provided capital to another pool or venue.

Model

  1. Total depth

  2. Share of the largest three addresses

  3. Split of the return into fees and incentive

  4. Remaining term of the incentive distribution, where stated

Four figures about a pool, in this order — The first number alone is the one quoted everywhere — and the only one of the four saying nothing about tomorrow.

Formulas

Share of the largest contributors

concentration_n = sum of the n largest contributions / total_depth
n
Number of largest addresses considered, commonly three or five
total_depth
Sum of all contributions in the pool

Limit: Addresses are not parties: one party can spread its contributions across many addresses, making measured concentration too low. The metric is therefore a lower bound on actual concentration, never an upper one.

Worked example

Same depth, different durability

Pool A — depth
USD 30m
Pool A — largest three addresses
14 % of depth
Pool A — return split
2.9 % fees, 0.4 % incentive
Pool B — depth
USD 30m
Pool B — largest three addresses
61 % of depth
Pool B — return split
0.3 % fees, 7.1 % incentive

In A many independent providers would have to withdraw at once, and the return hangs on usage. In B three decisions cover USD 18.3m, and the reason those three are present is 96 % the distribution.

The same USD 30m of depth, two entirely different statements about tomorrow.

Reading: For an exit calculation in B today's depth is the wrong basis while the timing of the exit is open. The defensible quantity there is depth less the contributions tied to the distribution — and where that attribution is impossible, it should be named as an uncertainty.

Retrieval

Two pools have the same depth. In one the largest three addresses hold 61 %. What follows?
How do you recognize rented liquidity?
