# Where does stablecoin yield come from? Stablecoin yield comes from an additional economic activity or distribution rule: borrower interest, reserve income, trading revenue, derivatives funding or incentives. The base token may pay nothing. To explain a quoted return, identify the payer, product, fees, variable rate and the risks taken to earn it.

([USDC Terms](https://www.circle.com/legal/usdc-terms)) - **Savings wrapper:** sUSDS represents a separate savings implementation for USDS. ([sUSDS: Savings USDS](https://developers.skyeco.com/protocol/tokens/susds/)) - **Variable income:** Derivatives funding can become a cost rather than revenue. ([Funding Risk](https://docs.ethena.fi/protocol-overview/risks/funding-risk)) ## Start with the activity that produces the return If a borrower pays interest, the provider earns income for supplying capital and taking the arrangement’s credit and liquidation exposure. If a reserve holds securities, its income comes from those securities. A derivatives strategy can earn funding or basis income. Promotional tokens are another category: they are a subsidy or reward, not automatically earned cash revenue. An advertised total can blend several sources. Separate the underlying-asset return from bonus tokens, points and temporary rewards. Their valuation and duration differ. A token price rising after distribution does not prove the operating strategy generated that gain.

One is a token; the other also carries the product’s rules and dependencies. Likewise, USDS and sUSDS are not identical balances. Sky documents sUSDS as an ERC-4626 savings vault in which shares represent underlying USDS. In an illustrative savings vault, 100 shares at 1.00 underlying unit per share represent 100 units. If the conversion rate becomes 1.05, the same 100 shares represent 105 units before any relevant costs or restrictions. A flat share count can therefore coexist with growth in the underlying amount.

Lending interest can change with utilization; incentive distributions can change; staking shares can have withdrawal conditions. For an illustrative 100-unit position earning two units, a five-unit principal loss leaves 97 units before other costs. Gross rewards and net outcome answer different questions. A higher share conversion measured in a stablecoin also does not guarantee a fixed value in dollars.

No. The distribution depends on the token’s terms. USDC terms do not give ordinary holders the reserve interest.

Funding costs, execution and counterparty or custody failures can affect it despite reduced directional exposure.
