Where Do Yield-Bearing Stablecoins Get Their Yield From?
The yield from yield-bearing stablecoins comes from actual interest income generated by their underlying collateral assets in the real world or within the crypto ecosystem, not from "creating money out of thin air." These stablecoins invest user-deposited funds into yield-generating channels (such as US Treasury bonds, staking, or lending) and then distribute the returns to holders. The yield is not "magic" from the stablecoin itself but the result of the underlying asset operations.
Prerequisite: Understanding Two Types of Yield-Bearing Stablecoins
The sources of yield vary by project but can be broadly divided into two categories. First, understand which type you are looking at:
RWA (Real-World Asset) yield-bearing stablecoins: Backed by real-world assets (such as US Treasury bills), with yield coming from interest in fiat markets.
Crypto-native yield-bearing stablecoins: Backed by on-chain assets (such as ETH, USDC), with yield coming from on-chain staking or lending activities.
Step 1: RWA Yield-Bearing Stablecoins — Yield Comes from Real-World Interest
What to do: Understand how the money in these stablecoins works.
How it works:
Typical examples of RWA yield-bearing stablecoins are USDM (interest-bearing stablecoin issued by Mountain Protocol), USYC (Hashnote's interest-bearing stablecoin), etc.
Mechanism: You deposit $1, and the project uses that money to purchase short-term US Treasury bills or similar low-risk bonds, earning an annualized 4%-5% interest. After deducting operating costs, the project returns the remaining interest to you.
Yield source (as of July 2026): The yield rate of yield-bearing stablecoins is linked to the US Federal Funds Rate, typically floating in the 4.5%-5.5% range.
Completion criteria: You understand that the yield from RWA yield-bearing stablecoins essentially means your money is lent to the US government (via Treasury bills), and the national credit is paying you interest.
Step 2: Crypto-Native Yield-Bearing Stablecoins — Yield Comes from On-Chain Activities
What to do: Understand how the money in these stablecoins generates yield on-chain.
How it works:
Typical examples of crypto-native yield-bearing stablecoins are sUSDe (Ethena's interest-bearing stablecoin), yieldETH, etc.
There are three main sources of yield:
Staking yield: The project deposits the stablecoin into liquid staking protocols like Lido to earn ETH staking rewards (annualized approx. 3%-4%).
Lending interest: Funds are deposited into lending protocols like Aave and Compound to earn interest paid by borrowers (annualized, fluctuates, typically 2%-10%).
Funding rate: In perpetual contract markets, gains are earned from the funding rate caused by the imbalance between long and short positions (annualized can be highly volatile, reaching 20%-30% in extreme conditions).
Composite yield: The project combines several of these yield sources and distributes them to holders of the yield-bearing stablecoin.
Completion criteria: You understand that the yield of crypto-native yield-bearing stablecoins comes from fees and interest generated by on-chain economic activities, not "created from nothing."
Step 3: Compare the Two Yield Sources with a Table
What to do: Visually compare the two types.
| Comparison Dimension | RWA Type (e.g., USDM, USYC) | Crypto-Native Type (e.g., sUSDe, yieldUSD) |
|---|---|---|
| Underlying Assets | US Treasury bills, short-term bonds | ETH staking, lending protocols, perpetual contract funding rates |
| Yield Source | Bond interest guaranteed by national credit | Yield from on-chain lending, staking, and arbitrage |
| Yield Stability | Relatively stable (linked to Fed interest rates) | Highly volatile (dependent on market activity) |
| Yield Level (Reference) | Approx. 4.5%-5.5% (as of July 2026) | Approx. 3%-20% (determined by market conditions) |
Step 4: Where Does the Yield Come From? Traceable Sources
What to do: Find the "proof of yield" for each yield-bearing stablecoin.
How to do it:
For RWA types, the project usually discloses the scale of Treasury holdings and yield rate data on its official website or in regular audits.
For crypto-native types, go to Dune Analytics or the project's official dashboard to check the protocol's revenue sources (such as specific data on lending interest and staking rewards).
Completion criteria: You have verified that a certain yield-bearing stablecoin's yield source is truly traceable and not just a "packaged" marketing pitch.
Common Reasons for Failure
Mistaking "high yield" for "risk-free yield": If the annualized yield is as high as 10%-20%, it very likely contains crypto-native risks (such as funding rate volatility, protocol vulnerability risks).
Not distinguishing between "stablecoin yield" and "stablecoin principal": The yield from holding yield-bearing stablecoins can be withdrawn, but the principal remains exposed to the risks of the underlying assets (e.g., Treasury default is extremely rare, but theoretically possible).
Ignoring fees deducted by the protocol: The project deducts a certain percentage from the total yield as operating expenses; the actual yield you receive is lower than the gross yield of the underlying assets.
Risk Reminders
The yield rate of yield-bearing stablecoins is not fixed and will fluctuate with market interest rates and on-chain activity. Do not take "annualized 5%" as a constant long-term expectation.
RWA yield-bearing stablecoins rely on the compliance of the issuer and the security of the custodian. If the custodian experiences credit problems, assets may be damaged.
In the yield composition of crypto-native yield-bearing stablecoins, funding rate income can be zero or even negative during market downturns, directly affecting overall returns.
How to Confirm You Understand the Yield Sources
Open the official documentation or audit report of your yield-bearing stablecoin and find the "Revenue Source" or "Reserves" section.
If it shows "US Treasury Bills" → Yield comes from RWA Treasury interest
If it shows "ETH Staking Yield", "Lending Interest", "Funding Rate" → Yield comes from crypto-native on-chain activities
If nothing is written or the description is vague → Be cautious, there may be a lack of transparency
Understanding where your money comes from is more important than just looking at annualized numbers. Find and read the official documentation and yield composition description of the coin you hold; this is more worth your time than paying attention to price fluctuations.
