Stablecoin Yield Guide
Where the APY actually comes from. Custodial vs DeFi vs RWA yield compared.
Short answer
Stablecoins have no native yield. Any APY comes from somewhere — centralised lending (Nexo, Ledn, Crypto.com), DeFi lending (Aave, Compound, Morpho), RWA-backed protocols (Maker DSR/SSR), or delta-neutral strategies (Ethena sUSDe). Rule of thumb: > 12% sustained = verify carefully. Safest: tokenised US Treasuries via Ondo or Franklin Templeton. For most users: Maker DSR or Aave on USDC provides a reasonable 4-7% with transparent mechanics.
Where stablecoin yield comes from
1. Centralised lending (Nexo, Ledn, Crypto.com)
You deposit USDC/USDT. The platform lends it to institutional borrowers — market-makers, prime brokers, hedge funds borrowing stablecoins for trading strategies. Yield = borrower interest rate minus platform spread. Typical 4-10%. Risk: counterparty — if borrowers default, the platform absorbs losses (or, in Celsius's 2022 case, users absorb losses).
2. DeFi lending (Aave, Compound, Morpho)
You deposit USDC into a smart contract. Other users borrow from the pool against over-collateralised positions (typically 150-200% collateralisation with ETH/BTC/stablecoin collateral). Yield = borrower interest paid to the pool, split among depositors. Typical 3-7%. Risk: smart-contract exploit, collateral liquidation failure in extreme volatility, oracle failure.
3. Real-world-asset (RWA) backed
Protocols like Maker (DAI), Ondo (OUSG), Franklin Templeton (BENJI), BlackRock (BUIDL) hold tokenised US Treasury bills or money-market funds. Yield tracks US T-bill rates. Maker DAI Savings Rate (DSR / newer SSR via Spark) is the largest decentralised variant. Typical 4-8% depending on Fed rate environment. Risk: issuer credit risk (if Ondo fails, the T-bills remain — but access may be disrupted), regulatory risk around tokenised securities.
4. Delta-neutral protocols (Ethena sUSDe)
Ethena stakes ETH, simultaneously shorts ETH perpetual futures to hedge price exposure, captures staking yield + funding-rate yield. Result: a "stablecoin" backed by delta-neutral positions paying 10-30% in favourable conditions. Risks: funding-rate flips negative (yield crashes), perpetual-futures infrastructure risk, exchange counterparty risk (hedges on Binance, OKX, Bybit), extreme-stress depeg. Not a direct competitor to USDC; a different product class with higher risk-return.
5. LP fees (liquidity provision)
Supply USDC+USDT or USDC+DAI to a DEX pool (Curve, Uniswap V3), earn share of swap fees. Impermanent loss is minimal for stablecoin-stablecoin pairs but non-zero during depeg events. Typical 2-6%. Risk: smart-contract exploit, underlying stablecoin depeg.
Safety hierarchy
- Tokenised Treasuries (Ondo OUSG, Franklin BENJI, BlackRock BUIDL) — conservative, yield tracks T-bills.
- Maker DSR/SSR via Spark — decentralised RWA exposure, good transparency.
- Aave/Compound/Morpho on USDC — largest-TVL DeFi lending, most audited.
- Custodial platforms (Nexo, Ledn, Crypto.com) — concentrated counterparty risk but audited. Prefer platforms with explicit counterparty-book transparency.
- Ethena sUSDe — legitimate innovation, higher risk than above.
- Unknown protocols with 20%+ sustained yield — assume red until proven otherwise.
Stablecoin choice matters
| Stablecoin | Backing | MiCA EMT-compliant? | Notes |
|---|---|---|---|
| USDC | Circle, audited cash + T-bills | Yes | EU-preferred; regulated issuer |
| USDT | Tether, cash + T-bills + other | No (EU delistings) | Highest liquidity but EU-restricted |
| DAI | Maker — crypto collateral + RWAs | N/A (algorithmic) | Decentralised; depeg risk in extreme stress |
| USDe | Ethena — delta-hedged ETH | N/A | Higher yield, higher risk |
| EURC / EURe | Circle / Monerium | Yes (EMT-compliant) | Euro-denominated; lower liquidity |
Red flags
- Sustained yield > 12-15% with no clear explanation of the yield source
- "Insurance" claims without a named, verifiable underwriter
- Yield that doesn't vary with market conditions (real yield varies)
- Referral/tier systems that seem more aggressive than the underlying yield can support (Ponzi signal)
- Offshore-only operation with no regulatory status
- Lock-ups longer than the yield-source justifies
