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.
