Returns depend on trading activity and pool terms, while depegs, smart-contract failures, changing liquidity and transaction costs can still produce losses. If your goal is income, compare an AMM pool’s swap-fee income with a lending market’s borrower-paid interest—and treat neither as fixed or automatically passive.
What does a stablecoin liquidity pool do?
A liquidity pool is a smart contract that holds cryptocurrency reserves so users can trade between assets. The National Institute of Standards and Technology describes a pool as a smart contract that maintains two or more cryptocurrencies and enables trading between them. People who supply assets are liquidity providers, or LPs; in return, they may receive a share of trading fees.

In a common constant-product AMM, the reserve quantities follow the relationship x × y = k. A trade changes the quantities held in the pool, which changes the implied exchange price. As a result, an LP’s position does not necessarily retain the same token mix it had at deposit. The LP’s fee share depends on its share of the relevant liquidity, and the fees earned depend on trading activity and pool terms.
Is it a good way to avoid impermanent loss and earn passive income?
It can be a way to seek fee income with less ordinary price divergence than a pair of volatile assets, but it is not a way to avoid loss altogether. Two stablecoins designed to track the same reference value may stay closer in price under ordinary conditions. If one loses its peg, however, the pool can become increasingly exposed to the impaired asset as traders exchange it for the asset they consider stronger.

“Impermanent” describes the fact that divergence loss can change if relative prices move back; it does not mean the loss is temporary or guaranteed to reverse. Uniswap’s explanation of returns for v2 notes that the result depends on the balance between trading fees earned and losses from directional price movements. Fees may offset that difference, but they may not.
Income is not necessarily passive in the everyday sense. A broad-range position may require less range adjustment than a concentrated position, but LPs still need to assess the pool, monitor material risks and account for entry, management and exit costs. Concentrated positions require particular attention because they stop earning fees when the market price leaves the chosen range.

Where does the return come from?
AMM liquidity: swap fees
An AMM LP earns a portion of eligible swap fees. The realized amount depends on trading volume, the pool’s fee structure and the LP’s share of active liquidity. A displayed annualized percentage is not a promised interest rate: it can change as trading and liquidity conditions change, and it does not by itself show whether the position’s changing token mix helped or hurt the result.

Lending markets: borrower-paid interest
A lending-market supplier deposits an asset for borrowers to use and earns the market’s supply rate under the protocol’s rules. Aave’s V3 documentation describes supplier interest and pool mechanics; it is a different activity from providing two-sided liquidity to an AMM. AMM swap fees and lending interest have different sources, so impermanent-loss analysis for a two-asset LP position should not be applied wholesale to lending.

No live APY for a named stablecoin pool is established here. A rate needs to be checked for the specific market and time, including what it counts, whether incentives are included, and what costs or conditions apply.
What risks remain even when both assets are stablecoins?
- Depeg and asset risk: A stablecoin’s name or design intent does not guarantee that its market price will stay at the target. A 2023 Xenophon Labs study examined depeg exposure in Curve StableSwap pools. In a retrospective result, its model detected the USDC depeg at 9 p.m. UTC on March 10, 2023, about five hours before USDC fell below $0.99. That historical detection is not a dependable warning system or investor protection.
- Divergence loss: When relative prices change, the pool adjusts its token composition. Your result can be worse than holding the original assets, even after accounting for fees.
- Smart-contract risk: A bug or exploit can put deposited funds at risk. Protocol documentation identifies contract risk as a concern for liquidity providers.
- Token and liquidity permissions: A permissionless pool can include tokens from untrusted teams. If a team has supplied liquidity and it is not locked, it may be able to remove that liquidity.
- Liquidity and transaction costs: Depositing, managing or exiting a position can incur network costs. Pool withdrawals can also affect the liquidity available for exchanges; NIST notes that excessive withdrawals may inhibit a pool’s exchange capacity.
- Changing rates and incentives: Trading activity, lending demand, liquidity and protocol parameters can change. A quoted or displayed yield may not represent what a depositor will realize over a different period.
How do the main options compare?
| Strategy | Main return source | What to examine | Distinctive trade-offs |
|---|---|---|---|
| AMM pool with a broad liquidity range | A share of swap fees | Fee tier, trading activity, your share of liquidity, assets, network and pool design | The token mix can change; fees vary; depeg, contract and network risks remain. |
| AMM pool with concentrated liquidity | A share of fees while liquidity is in range | Lower and upper price bounds, trading near that range, monitoring and repositioning costs | Liquidity outside the selected range earns no fees until price returns; narrower ranges require more active management. |
| Stablecoin lending market | Interest paid by borrowers | Current supply rate, borrowing demand, reserve and governance parameters, available liquidity and network | The rate varies with market conditions; smart-contract and liquidity risks remain. This is lending, not AMM liquidity provision. |
These are different sources of return, not interchangeable products that can be ranked by one APY snapshot. For context on how broad stablecoin pool markets can be, an American Finance Association-hosted study describes a research sample of 91,811 weekly observations across 1,359 pools, 194 protocols or projects, 44 blockchains and 669 token denominations, covering February 2022 through December 2024. Those are characteristics of that historical sample, not a live map of available markets or current yields.

How should you evaluate a pool or market before depositing?
- Identify the strategy. Confirm whether you are supplying assets to an AMM to earn swap fees or supplying an asset to a lending market to earn borrower-paid interest.
- Inspect the assets and peg assumptions. Understand what each stablecoin is intended to track and what could cause its market price to diverge. A pair of stablecoins is still exposed to the possibility that one performs differently from the other.
- Check what the quoted return includes. Find out whether it reflects fees or interest, token incentives, the measurement period and the relevant pool or market. Do not assume an annualized display is a fixed rate or a prediction of realized results.
- For AMMs, assess liquidity and position design. Consider the fee tier, trading activity, your share of active liquidity and, for concentrated liquidity, the selected price range and the costs of repositioning.
- For lending, inspect market conditions. Compare the current supply rate with borrowing demand, available liquidity and reserve or governance parameters; these help explain why the rate may change.
- Account for the full transaction path. Include network costs and the liquidity and conditions that could affect your ability to enter, manage and exit. A gross yield figure is not the same as a realized return.
- Decide what loss you can tolerate. Consider depeg, divergence, contract and liquidity risks in relation to the amount and duration you are considering. Do not treat historical depeg detection as a safeguard.
Protocol documents explain mechanics and categories of risk, not present-day pool conditions. Rates, incentives, liquidity, supported networks and governance parameters can change, so a decision about a particular position requires current, pool-specific information.
