USDC and USDT Yield Offers Rely on Six Different Payment Sources

USD Coin (USDC) and Tether (USDT) yield offers draw on six sources of payment, from fund portfolios to token incentives, leaving U.S. customers with different assets and risks behind similar quoted returns.

Holding a payment stablecoin does not itself explain a return. USDC holders have no claim to interest earned on Circle’s reserves. A yield offer instead depends on a separate fund, account program, lending position or trading arrangement. Its terms determine both who pays and what the customer holds.

The distinction matters when products display an annual percentage yield. A quoted rate may combine payments from more than one source, and those components can change for different reasons. The six routes below describe where the money comes from; they do not rank expected returns or safety.

Fund Income and Borrower Interest

A tokenized money market fund can distribute income from its portfolio after expenses. The Franklin OnChain U.S. Government Money Fund holds at least 99.5% of its assets in government securities, cash and qualifying repurchase agreements. Its yield moves with short-term interest rates rather than arising from USDC itself.

Franklin Templeton announced a USDC conversion service for certain institutional wallets. The conversion leaves an investor with a fund share, which has different redemption rights from the stablecoin used to obtain it. The fund seeks a $1 share price, but a share can lose value. The announcement did not establish general retail access to the conversion service.

Lending markets have a different payer: borrowers. They pay interest on loans backed by collateral, while the rate available to depositors changes with borrowing demand. A displayed annual percentage yield therefore describes a current rate, not a fixed payment for the coming year.

A Morpho vault may add rewards in another token to the interest generated by borrowers. Separating those amounts shows how much of the displayed return depends on loan activity and how much depends on an incentive. The lending position also depends on collateral, liquidations, available withdrawal liquidity and smart contracts.

Trading Fees and Futures Funding

A provider of liquidity to a USDC–USDT pool can receive part of the fees paid when traders swap the tokens. The amount depends on trading activity and the provider’s share of active liquidity. Where a pool uses a chosen price range, a position outside that range earns no swap fees until the price returns.

The position retains exposure to both tokens. If either loses its dollar peg, the change in the position’s value may exceed the fees it collected. A fee-based return therefore depends on both the pool’s trading activity and the value of the assets remaining in it.

Futures funding is a payment between traders, not income produced by a stablecoin balance. One strategy holds a crypto asset while shorting a matching perpetual futures contract to reduce exposure to changes in that asset’s price. When the funding rate is positive, traders holding long contracts pay those holding short contracts; a negative rate reverses the flow.

That payment can diminish or become a cost. The strategy must also maintain margin and account for trading costs, exchange exposure and a hedge that may fail. A customer entering a product built around this strategy holds a different exposure from someone simply holding USDC or USDT.

Platform Rewards and Token Incentives

An account reward has yet another payer. Coinbase funds its USDC Rewards program itself; the reward is not interest that every USDC holder receives from Circle’s reserves. U.S. retail eligibility requires Coinbase One membership, and the rate can vary by account and change over time. The membership cost affects the return a customer receives after expenses.

A lending vault or liquidity pool can also pay an additional reward in a separate token. Such incentives may raise the headline yield above the interest or swap fees generated by the underlying activity. Their dollar value changes with the reward token’s price, and the additional payments depend on the campaign continuing.

These sources can appear together in a single quoted figure. For example, a lending vault can show borrower interest alongside token rewards. Treating that combined rate as one payment obscures which portion responds to borrowing demand and which portion depends on an incentive program.

The label “yield bearing” does not identify the payment source or the asset held. A token may represent exposure to fund income or proceeds from a trading strategy. Exchanging USDC or USDT for that token can change its backing, redemption rights and risks.

U.S. law makes a further distinction between a payment stablecoin and products arranged around it. The GENIUS Act prohibits permitted payment stablecoin issuers and foreign payment stablecoin issuers from paying yield solely for holding, using or retaining their tokens once the law takes effect. That issuer restriction does not make a fund share, lending position and platform reward the same product. Its effective date is the earlier of Jan. 18, 2027, or 120 days after primary federal regulators issue final implementing regulations.
