Where Stablecoin Yield Comes From, and What Can Go Wrong
Stablecoin yield is paid by borrowers who want leverage, by issuers sharing the interest earned on their reserves, or by trading strategies, so the rate you are quoted is compensation for credit, contract, and platform risk rather than interest on a deposit.

Key takeaways
- Stablecoin yield is paid by borrowers, by issuers sharing reserve income, or by trading strategies, not by a bank paying interest.
- Ethereum.org states that strong demand to borrow stablecoins can create opportunities to earn interest rates of roughly 3 to 7 percent.
- Circle says the majority of the USDC reserve sits in an SEC-registered 2a-7 government money market fund with monthly third-party assurance from a Big Four accounting firm.
- The Financial Conduct Authority says it is highly unlikely a UK consumer would be covered by the Financial Services Compensation Scheme for crypto.
- A stablecoin holding its peg and the platform paying you yield are two separate risks that can fail independently.

Stablecoin yield is paid by borrowers who want leverage, by issuers sharing the interest earned on their reserves, or by trading strategies, so the rate you are quoted is compensation for credit, contract, and platform risk rather than interest on a deposit.
The framing matters more than the number. A quoted rate on a dollar-denominated token looks like a savings account rate, and the visual similarity is the single most misleading thing about the product. This page explains the mechanics, not whether any of it suits you, and it is not financial advice.
Three places the money actually comes from
Borrowers. This is the largest source. Someone wants dollars without selling the asset they hold, so they post collateral and borrow stablecoin against it, paying interest. Ethereum's documentation describes the effect: "strong demand to borrow stablecoins can create opportunities to earn above-average interest rates," and it puts the range at roughly "3 - 7% interest rate" for depositing into lending platforms (source: ethereum.org stablecoins documentation, September 2026). It also notes that "interest rates (APY) are determined by market activity and fluctuate based on real-time supply and demand."
That last sentence is the important one. The rate is not promised. It is the clearing price between people lending and people borrowing at that moment, and it falls when borrowing demand falls.
The issuer's reserves. A fiat-backed stablecoin is backed by assets that themselves earn interest. Circle states that "the majority of the USDC reserve is held in the Circle Reserve Fund (USDXX), an SEC-registered 2a-7 government money market fund" holding "cash, short-dated US Treasuries and overnight US Treasury repurchase agreements with leading global banks" (source: Circle transparency page, September 2026). Those assets produce income. Where a platform passes some of that income to holders, the yield is ultimately short-term government debt yield minus what the intermediaries keep, and it moves with central bank rates rather than with crypto demand.
Trading strategies. Some products pay a yield generated by a strategy: capturing the funding rate on perpetuals, market making, or arbitrage between venues. These can produce higher headline numbers and carry entirely different failure modes, because the yield depends on a position staying profitable.
| Source | Who pays | What the rate moves with |
|---|---|---|
| Borrowers | People posting collateral to borrow stablecoins rather than sell what they hold | Borrowing demand at that moment. Ethereum's documentation puts the range at roughly 3 to 7 percent for depositing into lending platforms |
| The issuer's reserves | The issuer, sharing income earned on reserve assets | Central bank rates, since the reserve holds cash, short-dated US Treasuries and overnight repurchase agreements |
| Trading strategies | A strategy that has to stay profitable | The profitability and risk of that strategy |
Two risks, not one
Holding a stablecoin and earning yield on it are separate decisions with separate ways to fail.
The peg risk belongs to the token. Ethereum's documentation describes fiat-backed stablecoins as instruments you "purchase at a 1:1 ratio with fiat and later redeem with the issuer for the original underlying currency, which is held in reserves." Its listed drawbacks are structural: they are "centralized, someone must issue the tokens," and the model "requires auditing to ensure company has sufficient reserves."
Issuers address that differently. Circle says "a Big Four accounting firm provides monthly third-party assurance that the value of USDC reserves are greater than the amount of USDC in circulation," under AICPA attestation standards, and that Deloitte & Touche LLP "has audited Circle's financials since fiscal 2022" (source: Circle, September 2026). Tether's public transparency page states that its tokens are "backed 100% by Tether's Reserves" and that "the Tether Issuer's assets exceed its liabilities," with figures published separately (source: Tether transparency page, September 2026). Compare what each issuer publishes, how often, and who signs it, and see USDC and Tether for the details we hold on each.
Ethereum's documentation also lists algorithmic designs as a separate category. The distinction that matters is whether there is an asset you can redeem against. A design that holds its peg through market incentives rather than redeemable reserves has nothing to redeem when confidence goes, and the peg and the yield tend to fail together rather than separately.
The platform risk belongs to whoever holds the position.
| Peg risk | Platform risk | |
|---|---|---|
| Belongs to | The token | Whoever holds the position |
| On a lending protocol | Whether there are redeemable reserves behind the token | The smart contract code, the oracle feeding it prices, and whether liquidations execute fast enough when collateral falls |
| On a cex | The same question about the token | The company: its solvency, its lending of customer assets, and its ability to keep withdrawals open |
| What reduces it | Redeemable reserves, published often, signed by someone independent | Nothing removes it. In defi the code is public and auditable, and it still fails |
Our guide on what happens when an exchange fails covers the exchange case, and the venues we track are at Exchanges.
There is no deposit insurance
This is the part that a percentage sign next to a dollar figure obscures.
Regulatory context differs by country, and ours is at United Kingdom and the other jurisdiction pages.
The general shape holds well beyond the United Kingdom. A stablecoin balance earning yield is a claim on a company or a contract, and government deposit guarantee schemes are built for bank deposits, not for that.
Questions worth asking before you accept a rate
| Question | Why it matters |
|---|---|
| Who is paying the yield, and why are they willing to | It identifies which of the three sources you are exposed to |
| What happens to your position if the rate goes to zero | Lending rates are a clearing price, not a promise |
| Can you withdraw immediately, or is there a lockup | Exits are most crowded exactly when you want one |
| Is the balance segregated or pooled with the platform's own funds | It decides where you stand if the platform fails |
| Does the quoted apy include a promotional component that expires | The headline may not be the steady-state rate |
| Is the yield paid in the same stablecoin or in a platform token | A platform token's value can move |
Tax does not disappear because the token is stable
Yield received is generally income at the value you received it, and disposing of a stablecoin is generally a disposal even though the price barely moved. Rules differ by country, and our guide to crypto tax basics sets out the mechanics most systems share. This page is not tax advice.
Frequently Asked Questions
Is a stablecoin yield the same as a savings account rate?
No. A savings account is a bank liability, often covered by a government guarantee scheme up to a limit. A stablecoin yield is payment for lending to borrowers or for exposure to a strategy, with no such scheme behind it.
Why do rates differ so much between platforms?
Because the underlying activity differs. A lending market rate reflects borrowing demand at that moment, an issuer-linked rate reflects short-term interest rates, and a strategy-linked rate reflects the profitability and risk of that strategy. Differences of several percentage points usually mean different risks, not better management.
Can a stablecoin lose its peg while I am earning yield?
Yes, and the two events are correlated. Stress that breaks a peg usually also stresses the platforms holding that stablecoin, so the moment you most want to exit is the moment exits are most crowded.
Does high total value locked mean a protocol is safe?
No. tvl measures how much is deposited, not how well the code, the collateral, or the oracle behaves under stress. Large protocols have failed and small ones have not.
What is the simplest way to reduce the risk?
Understand which of the three sources is paying you, keep the amount consistent with a total loss being survivable, and treat the platform and the token as two separate decisions rather than one.
