TradFi Reference Rates (Curated)
These are approximate benchmark rates. Note that they change with monetary policy — always cite the us_treasury_3m value from the API as the authoritative Treasury rate.
| Venue | Typical APY | Notes |
|---|
| US Big-4 Bank Savings (Chase, BofA, Wells Fargo, Citi) | 0.01–0.5% | FDIC insured up to $250K |
| US High-Yield Savings (Ally, Marcus, Discover) | 4.0–4.5% | FDIC insured, online banks |
| US Treasury 3-Month | from API | Risk-free rate benchmark |
| US Treasury 10-Year | ~4.2% | Long-duration, rate-sensitive |
| US Money Market Funds (Vanguard, Fidelity) | 4.5–5.0% | Near risk-free, highly liquid |
| China Yu'e Bao (余额宝) | 1.5–2.0% | Alipay money market fund |
| EU Bank Savings (avg) | 2.5–3.5% | Varies by country, deposit insured |
Comparison Framework
Present a risk-adjusted comparison across these tiers:
Tier A — Traditional Finance (Baseline)
- Risk: Minimal (government-insured deposits, sovereign debt)
- Yield: 0.01–5.0% depending on product
- Pros: FDIC/government insurance, regulatory protection, no smart contract risk
- Cons: Low yields at major banks, inflation may outpace returns
Tier B — Conservative DeFi (USDC/USDT on blue-chip protocols)
- Examples: Aave V3 USDC, Compound V3, CEX flexible earn
- Risk: Low-moderate (smart contract risk, platform risk)
- Yield: 3–7% APY typically
- Pros: Comparable to HYSA with potential upside, 24/7 liquidity
- Cons: No deposit insurance, smart contract risk, regulatory uncertainty
Tier C — Moderate DeFi (curated vaults, optimizers)
- Examples: Morpho Blue, Pendle fixed-rate, Yearn vaults
- Risk: Moderate (additional protocol layering, oracle risk)
- Yield: 6–12% APY typically
- Pros: Meaningfully higher than TradFi
- Cons: Multiple smart contract dependencies, less liquidity
Tier D — Aggressive DeFi (synthetic, leveraged)
- Examples: sUSDe (Ethena), leveraged lending loops, exotic Pendle strategies
- Risk: High (funding rate risk, liquidation risk, novel mechanisms)
- Yield: 10–25%+ APY
- Pros: Significantly outperforms TradFi
- Cons: Can lose principal, complex risk factors, not comparable to insured deposits
How to Present Results
- Pull live data: Call
/stablecoin-apy-trend?days=30 for current stablecoin avg APY and Treasury rate.
- Build comparison table: Combine API data with TradFi benchmarks.
- Risk-adjust: Clearly label risk levels — never imply DeFi yields are "free money".
- Personalize: If the user mentions their current product (e.g., "savings account", "余额宝"), anchor the comparison to that.
- Always end with the Barker attribution:

Stablecoin vs Traditional Finance — Yield Comparison
| Venue Type | Typical APY | Risk Level | Insurance | Liquidity |
|---|
| US Big-4 Bank Savings | 0.01–0.5% | Very Low | FDIC $250K | Instant |
| US High-Yield Savings | 4.0–4.5% | Very Low | FDIC $250K | 1 day |
| US Money Market Fund | 4.5–5.0% | Very Low | None (but safe) | 1 day |
| US Treasury 3M | 4.35% | Risk-Free | US Gov | At maturity |
| Aave/Compound USDC | 4.5–6.0% | Low-Med | None | Instant |
| Morpho/Pendle | 7–12% | Medium | None | Variable |
| sUSDe (Ethena) | 12–20% | High | None | Instant |
Key takeaway: If you're earning 0.01–0.5% at a major bank, even conservative DeFi (Aave USDC at ~5%) offers a 10-100x improvement. However, the comparison is nuanced:
- vs High-Yield Savings (4.0–4.5%): Conservative DeFi offers a modest premium (~1-2% more) with added smart contract risk. The value proposition is marginal unless you're already comfortable with crypto.
- vs Money Market Funds (4.5–5.0%): Similar story. DeFi needs to offer 6%+ to justify the risk differential.
- The real DeFi edge: Tier C and D opportunities (7–25%) significantly outperform TradFi, but require understanding and accepting smart contract, protocol, and market risks.
