Stablecoin Yield Products: Legal Status Across Major Jurisdictions

What does 'stablecoin yield' actually mean?

Yield on a stablecoin is the return a holder earns for keeping USDC, USDT, DAI, USDe, or SKY in a product rather than a wallet. It is not the same as the price of the stablecoin going up. The pegged token stays near one dollar by design; the yield is a separate income stream layered on top of custody.

That distinction matters legally. Regulators rarely police a stablecoin that holds its peg. They police the contract that pays the holder extra money on top of the peg. Different jurisdictions draw the line in different places, which is why a product can be a regulated bank deposit in one country and an alleged unregistered securities offering in another.

Three structural shapes cover most retail-facing stablecoin yield products in 2025. The first is the lending-pool wrapper, where a protocol like Aave takes USDC deposits and issues a tokenized receipt such as aUSDC that appreciates against the underlying. The second is the savings-rate model, exemplified by the Sky Savings Rate (formerly the Dai Savings Rate) on Sky Protocol, where a governance-set rate is funded by protocol revenue. The third is the synthetic-dollar carry model, used by Ethena's sUSDe, where yield comes from a long-spot, short-perp basis trade on ETH or BTC rather than from lending out user deposits.

The core legal risks for stablecoin yield products

The risks split into three buckets: regulatory risk, structural risk, and counterparty risk. Each jurisdiction amplifies them differently, but none of them disappears just because a protocol audits its smart contracts or posts a slick compliance page.

Regulatory risk. A protocol can be fully audited, fully collateralized, and still be treated as an unregistered securities offering if regulators decide its yield wrapper is an investment contract. The US SEC has signaled this view repeatedly since 2023, and enforcement actions have followed against unregistered yield products. In the EU, MiCA's Article 23 creates a hard prohibition on interest, which means the wrapper itself can become unlawful even if the underlying token is fully compliant.

Structural risk. Yield wrappers often promise returns that depend on a chain of intermediaries. sUSDe's yield depends on derivatives exchanges honoring the short leg. The Sky Savings Rate depends on Sky Protocol continuing to subsidize it from its own balance sheet. aUSDC's yield depends on Aave's borrow demand. If any link in the chain breaks, the yield can go to zero or negative. Historical examples include the USDC depeg in March 2023, when Circle revealed exposure to Silicon Valley Bank and aUSDC briefly traded below its intended peg.

Counterparty risk. Many yield products expose holders to custodians, stablecoin issuers, or centralized exchanges. USDT yield products route through Tether, which has never been audited by a Big Four firm. USDC yield products route through Circle, which is regulated in the US but still vulnerable to bank-run dynamics. Yield on centralized platforms like Coinbase or Kraken sits on top of exchange solvency, which has been tested in past blowups such as FTX in 2022.

There is also the risk of confusing 'yield' with 'rewards.' Many projects pay rewards in their own governance token rather than in stablecoins. These distributions are usually classified differently under securities law and are often the first target of enforcement when a protocol runs into trouble.

Where is stablecoin yield legal in 2025?

The short answer is: it depends on where the issuer sits, where the user sits, and how the yield is structured. A rough jurisdiction map follows, with the major regimes ranked from most restrictive to most permissive.

European Union: MiCA Article 23 ban on interest

The Markets in Crypto-Assets Regulation, in force since 2024, draws a sharp line in Article 23. Holders of asset-referenced tokens (ARTs) and e-money tokens (EMTs) issued in or marketed to the EU cannot be offered interest, defined as any remuneration paid in connection with the holding of the token for a minimum period of time. The rule applies to euro-denominated stablecoins such as EURCV and to non-euro tokens marketed to EU residents.

The carve-out is fees. MiCA permits rewards that are structured as fees for a service, such as a transaction fee rebate, a staking-style reward tied to active participation, or a discount on platform services. This is why products like Morpho's EU-facing vault and several French-registered fintech wrappers explicitly avoid the word 'interest' in their marketing and instead describe their distributions as 'service rebates' or 'loyalty rewards.'

The practical result is that a US resident earning the Sky Savings Rate through Sky Protocol's smart contracts may receive rewards that are lawful under US analysis but unlawful if the same product is marketed to an EU resident with the language of 'interest.' Jurisdictional marketing rules, not protocol rules, drive the difference.

United States: GENIUS Act and the SEC's evolving theory

The US has two overlapping layers. The first is the GENIUS Act, signed into federal law in 2025, which created a federal licensing regime for payment stablecoin issuers. Crucially, GENIUS prohibits non-bank issuers from paying yield or interest directly to holders of the licensed token. Bank issuers remain subject to existing banking-law rules on deposit interest.

GENIUS does not, however, regulate third-party yield platforms that sit on top of permitted stablecoins. Aave, Compound, Sky, and Ethena are not issuers of USDC or USDT; they are wrappers. The law's silence on wrappers is the legal gap the SEC has begun to fill through enforcement and guidance.

The SEC's theory, articulated in recent Wells notices, settled orders, and public statements from the Division of Enforcement, is that a tokenized yield wrapper can itself be an investment contract under the Howey test. The agency's argument runs as follows: (1) investors pool capital into a smart contract; (2) they expect profits derived from the efforts of others (the protocol team, governance token holders, or a centralized operator); (3) the wrapper is sold as a security; therefore (4) the wrapper must be registered or qualify for an exemption.

This theory has been applied unevenly. The SEC has so far avoided targeting fully on-chain, governance-minimized wrappers where the protocol is sufficiently decentralized, and has focused instead on products that include centralized points of control, active marketing to retail, and yield derived from off-chain assets. aUSDC on Aave's public deployment sits in a gray zone, while Ethena's sUSDe faces more scrutiny because its yield depends on centralized derivatives venues.

United Kingdom: e-money law and the fee-vs-interest split

The UK regulates fiat-backed tokens primarily under e-money rules administered by the Financial Conduct Authority. Until late 2024, the FCA's view was that any return paid to holders of e-money tokens counts as interest, which would require authorization as a deposit-taking activity. The FCA's CP25 consultation shifted this position, distinguishing between interest (prohibited for e-money issuers) and service fees (permitted).

UK-licensed fintechs can therefore offer stablecoin rewards structured as service fees, similar to the EU model, but cannot advertise a fixed or variable 'interest rate' on an e-money token. The FCA has also clarified that overseas yield wrappers accessed by UK residents fall under the same regime if the wrapper is marketed to UK consumers. Cross-border access to Aave or Compound is not, in itself, illegal, but marketing such access to UK residents without authorization is.

Singapore, Hong Kong, and the UAE: permitted with disclosure

Singapore's Monetary Authority regulates stablecoins under its Stablecoin Framework, finalized in 2023 and amended in 2024. The MAS permits yield on regulated stablecoins provided issuers disclose the source of yield, the risks, and the fact that yield is not guaranteed. Major Payment Institution licenses are required for platforms serving Singapore residents.

Hong Kong's Stablecoin Ordinance, passed in 2025, takes a similar approach: yield is permitted on HKMA-licensed stablecoins, with disclosure rules and capital requirements for issuers. The Hong Kong Securities and Futures Commission has separately taken the view that tokenized yield wrappers may be collective investment schemes, requiring SFC authorization.

The UAE, particularly the Dubai financial free zone under VARA, allows stablecoin yield products with disclosure and licensing. Abu Dhabi's ADGM has issued similar guidance. Both jurisdictions are actively courting crypto yield platforms that have exited the US or EU.

Switzerland, Liechtenstein, and other permissive regimes

Switzerland's FINMA treats stablecoins as either payment tokens or assets subject to collective investment scheme law, depending on structure. Yield-bearing stablecoins that meet certain conditions can be approved as structured products, with prospectus and risk disclosures. Sky Protocol's Swiss Foundation, which publishes the Sky Savings Rate, operates from this jurisdiction.

Liechtenstein, through its Token and Trusted Technology Service Provider Act, has approved several tokenized yield products under its regulated blockchain framework. Other smaller jurisdictions, including the British Virgin Islands, the Cayman Islands, and Panama, host protocol entities but rely on offshore structuring rather than explicit licensing.

Sky Savings Rate vs Aave aUSDC vs Ethena sUSDe: the legal differences

These three products illustrate the spectrum of legal exposure in 2025. They are often grouped together as 'stablecoin yield,' but each rests on a different legal foundation.

Sky Savings Rate (formerly Dai Savings Rate). The SSR is a governance-set rate paid to holders of SKY who lock their tokens into the Sky Protocol. Because Dai is issued by a Swiss foundation and the SSR is set by decentralized governance rather than a centralized operator, US regulators have so far declined to treat the SSR as a security. The EU position is more complicated: marketing the SSR to EU residents as 'interest' would breach MiCA Article 23, and Sky's EU-facing materials therefore describe the distribution as a 'governance reward.'

Aave aUSDC. aUSDC is a receipt token that represents a depositor's share of USDC supplied to Aave's lending pools. The yield comes from variable borrow demand. Aave Labs, the US-incorporated developer, has argued that aUSDC is not a security because it is fully collateralized, redeemable at par, and not marketed with profit expectations. The SEC has not publicly agreed, but enforcement actions against Aave have been limited. In the EU, aUSDC distributions are typically framed as 'variable service fees.'

Ethena sUSDe. sUSDe is the most legally exposed of the three. Its yield is synthetic, derived from a long-spot, short-perp basis trade executed across centralized exchanges. The SEC has reportedly opened an inquiry into whether sUSDe is an unregistered security, with the argument that (1) USDe holders pool capital, (2) the basis trade is managed by Ethena Labs, and (3) returns depend on the team's execution. Ethena has responded by restricting US access, requiring KYC for US persons, and structuring the product through a Swiss foundation. The product remains legally available in most non-US jurisdictions.

What this means for a US-based stablecoin yield user

If you are a US resident earning yield on USDC, USDT, DAI, or USDe in 2025, the practical guidance is layered.

First, the underlying stablecoin matters less than the wrapper. Holding USDC in a wallet is not a securities issue; depositing USDC into an unaudited yield wrapper is a potential one. Audit the wrapper's legal opinion, not just its smart contract.

Second, marketing matters. Many protocols restrict US persons by IP-blocking, KYC, or terms of service. Bypassing these restrictions is itself a violation of the platform's terms and can complicate any future dispute. If a product is not available to you, the regulatory system is signaling that you should not use it.

Third, tax treatment is a separate question from legality. The IRS treats most crypto yield as ordinary income at receipt and capital gain on disposition, regardless of whether the wrapper is a security. Keeping clean records is essential.

Fourth, jurisdictional shopping has limits. Swiss, Singaporean, and Cayman entities are still reachable by US regulators through anti-fraud provisions, and the SEC has used aiding-and-abetting theories against overseas platforms that solicit US customers. A protocol that says it is 'not available in the US' may still be reaching you with marketing content you see online.

How to follow stablecoin yield regulation the smart way

Stablecoin yield regulation moves on three clocks at once: MiCA implementing rules in the EU, SEC enforcement in the US, and licensing decisions in Singapore and Hong Kong. Tracking them manually, across multiple regulators and dozens of protocols, is a losing game.
