Yield-Bearing Stablecoin

What Is a Yield-Bearing Stablecoin?

A yield-bearing stablecoin is a cryptocurrency token pegged to a stable value (typically the U.S. dollar) that generates passive income for its holders. Standard stablecoins like USDC and USDT invest their reserves into Treasury bills and other instruments but keep all the revenue. Yield-bearing stablecoins route those returns back to token holders, combining price stability with an income-generating mechanism.

The concept emerged as stablecoin issuers began earning billions from reserves while holders received nothing. In 2023, Tether earned over $6 billion from its reserves. This created a market opening: stablecoins that share reserve income with holders. By mid-2026, yield-bearing stablecoins have grown to over $11 billion in total market capitalization, though they still represent roughly 4% of the broader stablecoin market.

How It Works

Yield-bearing stablecoins combine a peg mechanism with a yield engine. The issuer invests reserves into income-producing assets and distributes returns to holders. The underlying yield sources fall into three categories:

• Government securities: short-duration U.S. Treasury bills, Treasury repos, and money-market instruments (used by USDY, YLDS, and sFRAX)
• DeFi lending: deploying collateral into lending protocols like Aave, Compound, and Morpho (used by Origin Dollar)
• Derivatives-based strategies: capturing perpetual futures funding rates via delta-neutral hedging, where the protocol holds spot crypto and shorts equivalent perpetual futures positions (used by Ethena's sUSDe)

Rebasing Model

In the rebasing model, the token price stays pegged at approximately $1.00, but the number of tokens in the holder's wallet increases automatically via periodic rebases. If you hold 1,000 tokens earning 5% APY, after one year you would hold roughly 1,050 tokens, each still worth $1.

The primary example is Origin Dollar (OUSD), backed by a USDC/USDT/DAI basket deployed into DeFi lending protocols. As of mid-2026, OUSD offers approximately 5.4% APY.

The drawback of rebasing is integration complexity. Changing token balances can break smart contract logic in AMMs and DeFi protocols, since contracts often cache balance snapshots that become stale after a rebase.

Reward-Accruing Model

In the reward-accruing (or "wrapped") model, the token count in the holder's wallet stays constant, but the redemption value of each token increases over time. A token minted at $1.00 might be redeemable for $1.05 a year later. This is the dominant model as of 2026, used by sUSDS, sDAI, sUSDe, and USDY.

Many reward-accruing tokens implement the ERC-20 standard with an ERC-4626 tokenized vault interface. This standardized wrapper makes integrations predictable:

// ERC-4626 vault interface (simplified)
interface IERC4626 {
  // Deposit stablecoins, receive yield-bearing shares
  function deposit(uint256 assets, address receiver)
    external returns (uint256 shares);

  // Redeem shares for underlying stablecoins + accrued yield
  function redeem(uint256 shares, address receiver, address owner)
    external returns (uint256 assets);

  // Preview how many assets a share is currently worth
  function convertToAssets(uint256 shares)
    external view returns (uint256 assets);
}

The convertToAssets function returns an increasing value over time, reflecting yield accumulation. DeFi protocols can integrate this interface without special logic for balance changes.

Major Examples

sUSDS (Sky)

sUSDS is the primary savings product of the Sky protocol (formerly MakerDAO). Users deposit USDS into the Sky Savings Rate module and receive sUSDS shares that appreciate in value. The yield comes from Sky's protocol revenue: stability fees on overcollateralized loans and returns from real-world asset investments. The Sky Savings Rate sits at approximately 3.5% APY as of mid-2026, with sUSDS circulating supply exceeding $5.5 billion.

The predecessor token, sDAI, uses the same ERC-4626 pattern with the Dai Savings Rate (DSR). Sky governance has been guiding users toward sUSDS as the primary savings product, though sDAI remains available.

sUSDe (Ethena)

Ethena's sUSDe takes a different approach. Rather than investing in Treasuries, it uses a delta-neutral strategy: holding spot crypto as collateral while shorting equivalent perpetual futures positions. The yield comes from perpetual futures funding rates, which are historically positive because leveraged traders pay to maintain long positions. As of Q2 2026, sUSDe offers a 7-day trailing APY around 9.4%, with roughly $1.5 billion in circulating supply. Each sUSDe token has appreciated to approximately $1.24, reflecting accumulated yield since launch.

USDY (Ondo Finance)

USDY is a tokenized note issued by a bankruptcy-remote special purpose vehicle. Its reserves are approximately 98.7% U.S. Treasuries, with an overcollateralization ratio of roughly 106%. As of mid-2026, USDY offers approximately 4.65% APY and has over $2 billion in circulating supply. Each token has appreciated to about $1.14. USDY is available to non-U.S. individual and institutional investors.

YLDS (Figure Markets)

YLDS, launched in February 2025, is notable as the first SEC-registered yield-bearing stablecoin. It explicitly registers as a security under U.S. law, making it available to U.S. retail investors. YLDS offers approximately 3.8% APY, with interest accruing daily and paying out monthly. It is issued on the Stellar network.

Comparison Table

Yield vs. Traditional Savings

Understanding how stablecoin yield compares to traditional alternatives helps frame the risk-reward tradeoff. The U.S. national average savings account rate sits at approximately 0.39% APY. High-yield savings accounts offer 4% to 5% APY with FDIC insurance up to $250,000.

Treasury-backed yield-bearing stablecoins (USDY at 4.65%, YLDS at 3.8%) offer rates comparable to high-yield savings accounts because they hold similar underlying assets. The key difference: no stablecoin carries FDIC insurance. DeFi-sourced yields (OUSD at 5.4%) and derivatives-based yields (sUSDe at 9.4%) offer higher returns that reflect genuinely higher risk, not free upside.

Why It Matters

Yield-bearing stablecoins address a fundamental inefficiency in crypto markets. Billions of dollars sit in standard stablecoins earning nothing for holders while issuers collect reserve income. For users holding stablecoins as dollar-denominated savings, yield-bearing variants offer a way to preserve purchasing power against inflation without leaving the on-chain ecosystem.

In the Spark ecosystem, USDB represents a yield-bearing stablecoin that distributes returns to holders in Bitcoin, combining dollar stability with Bitcoin accumulation. This approach demonstrates how yield-bearing stablecoins can serve as building blocks for novel financial products on Bitcoin Layer 2 networks.

The broader trend toward tokenized Treasuries is accelerating: on-chain Treasury fund assets surged from roughly $750 million in early 2024 to nearly $11 billion by early 2026, underscoring institutional demand for yield-bearing digital dollar instruments.

Use Cases

• On-chain treasury management: DAOs and protocols hold yield-bearing stablecoins instead of idle USDC to earn returns on their reserves without active management
• DeFi collateral: yield-bearing stablecoins serve as collateral in lending protocols, earning yield even while locked as margin or in liquidity positions
• Dollar savings in emerging markets: users in countries with limited access to U.S. Treasury products can hold tokenized Treasury exposure through stablecoins like USDY
• Payment float optimization: businesses that hold stablecoin balances for payment operations can earn yield on funds that would otherwise sit idle between settlement cycles

Regulatory Landscape

The regulatory treatment of yield-bearing stablecoins differs sharply from standard payment stablecoins. Because they offer returns to holders, yield-bearing stablecoins generally satisfy the "expectation of profit" prong of the Howey test, making them likely securities under U.S. law.

United States

The GENIUS Act, signed into law in July 2025 as the first comprehensive U.S. stablecoin legislation, explicitly prohibits "covered stablecoin" issuers from offering any form of interest or yield to holders. This means payment stablecoins are excluded from securities classification, but they cannot offer yield. Yield-bearing tokens like YLDS must instead register as securities with the SEC.

For a detailed analysis of how these rules affect stablecoin design, see the research on GENIUS Act stablecoin regulation and the stablecoin yield prohibition debate.

European Union

MiCA categorically prohibits issuers of e-money tokens and asset-referenced tokens from granting interest or any benefit related to holding those tokens. This effectively bans yield-bearing stablecoins from EU markets under the MiCA framework.

Risks and Considerations

Smart Contract Risk

Yield-bearing stablecoins rely on smart contracts for deposit, withdrawal, and yield distribution logic. Bugs, exploits, or vulnerabilities in these contracts could result in loss of funds. Protocols using DeFi lending strategies face compounded smart contract risk across multiple integrated protocols.

Reserve Composition Risk

The safety of a yield-bearing stablecoin depends on its reserve composition. Treasury-backed tokens like USDY carry relatively low credit risk but face custody chain dependencies. DeFi-sourced yields introduce counterparty risk across lending protocols. Derivatives-based strategies (like sUSDe) face exchange counterparty risk and the possibility of sustained negative funding rates, which can erode returns.

Depeg Risk

While yield-bearing stablecoins maintain dollar exposure, their secondary market prices can deviate from fair value during stress events. Depeg risk manifests differently depending on the design: Treasury-backed tokens face redemption queue delays, while derivatives-based tokens face forced unwind risk during extreme market moves. The UST collapse in May 2022 demonstrated how quickly confidence can evaporate in yield-bearing designs with insufficient backing.

Regulatory Uncertainty

The GENIUS Act's yield prohibition and MiCA's interest ban create a fragmented regulatory landscape. Yield-bearing stablecoins operating outside explicit securities registration face enforcement risk. Issuers must navigate differing frameworks across jurisdictions, and regulatory clarity continues to evolve.

Yield Sustainability

Yields depend on underlying market conditions. Treasury rates fluctuate with monetary policy. DeFi lending rates compress as more capital enters. Funding rates (Ethena's yield source) can turn negative during bear markets. Advertised APYs are snapshots, not guarantees, and historical returns do not predict future performance. For context on the stablecoin trilemma, adding yield introduces additional tradeoffs between stability, decentralization, and capital efficiency.
