Yield-Bearing Stablecoins Compared: sDAI, sUSDe, USDY, and More

Yield-Bearing Stablecoins Overview

Yield-bearing stablecoins are tokens that passively accrue interest while maintaining a dollar peg. Unlike standard stablecoins such as USDC or USDT, which generate no return for holders, yield-bearing variants like sDAI, sUSDe, and USDY pass protocol revenue or real-world asset returns directly to token holders. The sector has grown rapidly: from roughly $1 billion in 2023 to over $19 billion by the end of 2025, with projections exceeding $50 billion in 2026.

The yield sources vary dramatically across products. Some derive returns from U.S. Treasury bills, others from DeFi lending revenue, and others from derivatives-based basis trades. These differences produce very different risk profiles, regulatory classifications, and composability characteristics. The following table provides a high-level comparison of the major yield-bearing stablecoins available today.

For a broader comparison of where to earn yield on existing stablecoins through lending and staking, see the stablecoin yield comparison tool. For background on how these mechanisms work, read our research on yield-bearing stablecoins explained.

How Yield-Bearing Stablecoins Work

Yield-bearing stablecoins generate returns through three broad categories of mechanism. Understanding the yield source is essential for assessing the risk you take on when holding these tokens.

Treasury Bill and RWA Yield

Tokens like USDY, BUIDL, and YLDS invest holder deposits directly into short-duration U.S. Treasuries and bank demand deposits. The yield closely tracks the federal funds rate, which stood at 3.50–3.75% as of Q2 2026. These products function as on-chain money market funds: low volatility, predictable returns, and relatively straightforward risk profiles. The tradeoff is that yields will compress alongside rate cuts, and holders are exposed to the issuer's custody and operational risk.

Protocol Revenue Distribution

sDAI and its successor sUSDS derive yield from Sky (formerly MakerDAO) protocol revenue. The Dai Savings Rate and Sky Savings Rate are governance-set parameters that distribute a portion of income earned from RWA allocations (primarily T-bills) and lending fees on lending protocols like Spark. The rate is not market-driven: Sky governance votes to adjust it based on protocol economics and competitive positioning.

Basis Trade Yield

Ethena's sUSDe takes a fundamentally different approach. USDe is a synthetic dollar backed by a delta-neutral position: long staked ETH (earning ~3–4% staking rewards) paired with an equivalent short position in ETH perpetual futures. When the funding rate is positive (which it typically is in bullish markets), shorts receive payments from longs. Combined with staking yield, this produces the highest APY in the category: a 90-day trailing average of 11.8% as of April 2026. The tradeoff: extended periods of negative funding rates can erode returns, and the strategy depends on centralized exchange counterparties for the derivatives leg.

Value-Accruing vs. Rebasing Tokens

Most yield-bearing stablecoins use one of two mechanisms to distribute yield. The distinction matters for DeFi composability, accounting, and tax treatment.

Value-accruing tokens (sDAI, sUSDe, USDY, sfrxUSD) maintain a constant token balance while increasing the exchange rate against their underlying asset. One sDAI redeems for progressively more DAI over time. This follows the ERC-4626 vault standard, which makes the token compatible as collateral in lending markets, LP positions, and other DeFi composability layers.

Rebasing tokens increase the holder's token balance directly. Mountain Protocol's USDM used this approach: your wallet balance grew daily while each token maintained a $1 peg. While simpler to understand, rebasing breaks compatibility with many DeFi protocols that assume static balances. USDM has since initiated an orderly wind-down, and no major yield-bearing stablecoin launched in 2025 or 2026 uses the rebasing model.

Risk Comparison

Yield-bearing stablecoins span a wide spectrum of risk. Higher yields generally correlate with higher risk, but the nature of that risk varies significantly across products.

The Ethena Risk Profile

Ethena warrants special attention because it offers the highest yield but carries the most complex risk profile. The USDe basis trade depends on perpetual futures funding rates remaining positive. During the October 2025 market crash (the largest liquidation cascade in crypto history, with $19 billion liquidated), USDe dropped to $0.65 on Binance. While this was a Binance-specific oracle failure rather than a fundamental depeg (the Curve pool price remained near peg), it triggered a confidence crisis: USDe supply shrank from $14.7 billion to roughly $6.4 billion in two months. Ethena's reserve fund stood at $61 million as of March 2026, roughly 1.1% of outstanding USDe supply.

Regulatory Risk Under the GENIUS Act

The GENIUS Act, signed in July 2025 with an effective date of January 18, 2027, explicitly prohibits permitted payment stablecoin issuers from paying yield or interest to holders. This means yield-bearing stablecoins must either register as securities (like YLDS), register as money-market funds (like BUIDL), or restrict access for US retail users (like USDY under Regulation S). The OCC's proposed implementing rules, with a comment period that closed in May 2026, would extend this prohibition to issuer affiliates and third parties. This regulatory landscape represents the single largest structural risk for the yield-bearing stablecoin sector in the US.

Yield-Bearing Stablecoins vs. Lending Yields

A common confusion is between yield-bearing stablecoins and the returns from depositing standard stablecoins into lending protocols like Aave or Compound. The mechanisms are structurally different.

Lending yields come from borrowers paying interest on loans. The rate is algorithmically set by utilization ratios: when many borrowers want USDC and few suppliers exist, rates spike. When demand drops, rates collapse. As of Q2 2026, Aave v4 pays 5–6% variable on USDC supply, Compound V3 returns 3–5%, and Morpho Blue vaults range from 4–8%. These rates can change within hours.

Yield-bearing stablecoins derive returns from protocol revenue (sDAI, sUSDS), real-world assets (USDY, BUIDL), or derivatives strategies (sUSDe). The rates are more predictable: T-bill-backed products closely track the federal funds rate, while governance-set rates like the Sky Savings Rate change only through formal proposals. The key composability advantage is that value-accruing tokens like sDAI are standard ERC-20 tokens. You can deposit sDAI as collateral in Morpho or pair it in liquidity pools, stacking the passive savings rate underneath an active DeFi strategy. Lending deposits (like Aave's aUSDC) are locked in that specific market.

How to Choose a Yield-Bearing Stablecoin

The right choice depends on your risk tolerance, jurisdiction, and intended use case.

If you prioritize safety and predictability: USDY or BUIDL offer T-bill-backed returns with straightforward risk profiles. BUIDL requires a $5 million minimum and institutional KYC. USDY is accessible to non-US retail users with lower minimums but carries a 40–50 day lock-up for smaller deposits.

If you want DeFi composability: sUSDS (the successor to sDAI) is the standard. As an ERC-4626 vault token, it integrates seamlessly with lending protocols, DEX liquidity pools, and yield aggregators across Ethereum and its L2s. The ~3.6% APY is modest but predictable, and the yield has a long track record.

If you are chasing higher yields and accept the risk: sUSDe offers 9–12% APY during favorable funding rate environments. Be prepared for significant yield compression during bearish periods and understand the CEX counterparty dependency. The October 2025 episode demonstrated how quickly confidence can erode.

If regulatory clarity matters: YLDS is the only yield-bearing stablecoin registered with the SEC as a public security, offering ~3.85% APY with clear legal standing. For Bitcoin-native stablecoin needs without yield requirements, Spark supports USDB for instant, near-zero fee dollar transfers on Bitcoin.

Redemption Mechanics Compared

How quickly you can exit a yield-bearing stablecoin matters, especially during market stress when everyone tries to redeem at once.

• sDAI / sUSDS: instant redemption via the vault contract, no lock-up period, no minimum
• sUSDe: unstaking requires a 7-day cooldown period before USDe is returned; USDe itself redeems 1:1 against collateral
• USDY: redemptions above $100,000 process immediately with a Temporary Global Certificate; smaller amounts face a 40–50 day waiting period; fiat-only redemption to non-US bank accounts
• BUIDL: daily liquidity for institutional holders through BNY Mellon
• YLDS: standard settlement through the Provenance Blockchain transfer agent
• sfrxUSD: instant redemption via the vault contract, similar to sDAI

Frequently Asked Questions

What are yield-bearing stablecoins?

Yield-bearing stablecoins are dollar-pegged tokens that automatically generate returns for holders. Unlike standard stablecoins like USDC or USDT, which sit idle in your wallet, yield-bearing variants like sDAI, sUSDe, and USDY pass through interest from Treasury bills, DeFi lending revenue, or derivatives strategies. Most use a value-accruing model where the token's exchange rate against the underlying asset increases over time rather than your balance changing.

Are yield-bearing stablecoins safe?

Safety varies significantly across products. T-bill-backed tokens like USDY and BUIDL carry relatively low risk, comparable to holding a money market fund. Protocol-revenue tokens like sDAI carry smart contract and governance risk. Basis-trade tokens like sUSDe carry additional counterparty and funding rate risk. No yield-bearing stablecoin is FDIC insured, and all carry some combination of smart contract, counterparty, and regulatory risk. Higher yields generally indicate higher risk.

How does sUSDe generate such high yields?

Ethena's sUSDe earns yield from two sources: staking rewards on the long ETH position (~3–4%) and funding rate payments on short perpetual futures positions (variable, often 5–15%+ in bullish markets). When funding rates are positive, shorts receive payments from longs. This basis trade strategy can produce 9–12% or higher during favorable conditions but compresses to low single digits or even zero during extended bear markets when funding turns negative. Ethena's reserve fund absorbs negative funding periods so sUSDe holders never see negative yield directly.

Will yield-bearing stablecoins be banned in the United States?

Not banned, but regulated. The GENIUS Act (effective January 2027) prohibits "permitted payment stablecoin" issuers from paying yield, but it does not prohibit yield-bearing tokens that register as securities or money-market funds. YLDS has already navigated this by registering with the SEC. BUIDL operates as a registered fund. Other products like USDY exclude US persons entirely under Regulation S. The regulatory framework is pushing yield-bearing tokens toward securities classification rather than outright prohibition.

What is the difference between sDAI and sUSDS?

sDAI is the legacy savings token from MakerDAO, while sUSDS is its successor under the rebranded Sky Protocol. Both are ERC-4626 vault tokens that accrue yield from protocol revenue. The key difference is the underlying rate: the Sky Savings Rate (SSR) for sUSDS sits 50–100 basis points above the Dai Savings Rate (DSR) for sDAI. As of Q2 2026, sUSDS earns 3.60–3.75% while sDAI earns roughly 2.75–3.25%. Most capital has migrated from sDAI to sUSDS, with the sUSDS pool holding approximately $4.5–5.5 billion.

Can I use yield-bearing stablecoins as collateral in DeFi?

Yes, and this is one of their primary advantages. ERC-4626 tokens like sDAI, sUSDS, and sUSDe are standard ERC-20 tokens that can be used as collateral in lending protocols (Morpho, Aave), paired in AMM liquidity pools, or deposited into yield aggregators. This lets you stack the passive savings rate underneath an active DeFi strategy. USDY can also be used as DeFi collateral on supported chains, though its non-standard token mechanics require protocol-level integration.

How do yield-bearing stablecoin yields compare to savings accounts?

As of Q2 2026, top US high-yield savings accounts offer 4.10–5.00% APY (FDIC insured), while the national average is 0.38%. T-bill-backed yield stablecoins like USDY (4.65%) and BUIDL (3.5–4%) offer comparable returns without FDIC insurance. Protocol-revenue tokens like sUSDS (3.6–3.75%) trail the best savings accounts slightly. Basis-trade tokens like sUSDe (9–12%) significantly outperform but carry correspondingly higher risk. The 10-year Treasury yield stood at 4.55% as of early June 2026 for reference.
