Staking APY (Annual Percentage Yield) is the annualized compound rate of return earned by locking cryptocurrency tokens in a staking mechanism — whether that means running or delegating to a Proof-of-Stake validator, locking tokens in a protocol’s staking contract for governance rewards, or supplying liquidity in exchange for protocol emissions — expressed as the effective annual yield after accounting for the compounding of rewards, as opposed to APR (Annual Percentage Rate), which states the simple interest rate before compounding effects. In DeFi, “staking APY” is used loosely across several meaningfully different contexts: native PoS validator rewards, liquid staking protocol yields, and protocol-incentivized “staking” that is really just liquidity mining under another name — each carrying fundamentally different risk profiles despite similar labels.
APY vs. APR
The distinction between APY and APR is critical for evaluating staking returns:
| APR | APY | |
|---|---|---|
| Definition | Simple annual rate, no compounding | Effective annual rate with compounding |
| Formula | Rate × Time | (1 + Rate/n)^n − 1 |
| When equal | Only when n = 1 (annually compounded) | — |
| Higher figure | APR is lower | APY is higher (except at very low rates) |
| Favored by | Protocols quoting borrow costs | Protocols marketing deposit yields |
Example: A 10% APR compounded daily becomes:
$$text{APY} = left(1 + frac{0.10}{365}right)^{365} – 1 approx 10.52%$$
Protocols often quote the more attractive number. A lending protocol might quote APY on supply rates (to look higher) and APR on borrow rates (to look lower) — both technically accurate, but intentionally asymmetric.
Types of Staking and Their APY Sources
1. Native Proof-of-Stake Validation
Example: Ethereum staking yields ~3–4% APY (2024–2025), funded by ETH issuance to validators and priority fees
Characteristics:
- Denominated in the native token
- Real yield component (fees) + inflationary component (issuance)
- Rate decreases as more ETH is staked (yield dilutes across more validators)
Ethereum staking APY formula:
$$text{APY} approx frac{text{Base rewards} + text{MEV} + text{Priority fees}}{text{Total staked ETH}} times text{Compounding factor}$$
2. Liquid Staking Protocol Yield
Example: stETH earns ~3.5% APY (Ethereum base yield minus Lido’s 10% cut)
Characteristics:
- Auto-compounds via rebasing (stETH) or exchange rate growth (wstETH, rETH)
- Yield is “real” in the sense it comes from actual network security work
- Slight discount to raw validator yield due to protocol fees
3. Protocol-Native Staking (Governance/Revenue Sharing)
Example: GMX stakers earn ETH/AVAX fees + esGMX emissions; Curve veCRV holders earn 3CRV fees
Characteristics:
- Fee component is “real yield” (from actual protocol usage)
- Emission component is inflationary (existing holders are diluted)
- Yield varies with protocol usage volume
4. Incentivized/Liquidity Mining “Staking”
Example: Depositing LP tokens into a farm and earning token X as reward
Characteristics:
- Not true staking — the underlying asset is earning emissions, not network rewards
- Yield is inflationary by definition (new tokens created)
- Highly variable; typically front-loaded and unsustainable long-term
- APYs of 100–10,000% in early DeFi protocols were almost entirely this category
What Drives Staking APY
For PoS Networks:
|—|—|
| More validators join | APY decreases (rewards split among more) |
| Network activity / gas fees increase | APY increases |
| Token price increases (if APY in USD) | APY increases in dollar terms |
| Inflation rate reduced (e.g., Ethereum’s EIP-1559) | Less inflationary pressure |
For Protocol Staking:
|—|—|
| More tokens staked | APY decreases (same rewards, more recipients) |
| Protocol fee revenue increases | APY increases |
| Token emissions reduced | APY decreases |
| Token price increases (for emission rewards) | APY increases in USD terms |
Real Yield vs. Inflationary Yield
One of the most important distinctions in evaluating staking APY:
Real Yield: Denominated in assets earned from actual protocol revenue (fees, spreads). If you earn 5% APY in ETH from staking ETH, that ETH came from transaction fees and block rewards — real economic activity.
Inflationary Yield: Denominated in newly created tokens. Earning 50% APY in “FARM” tokens that are being continuously minted means existing holders are diluted. The 50% APY is not additive to your real purchasing power — it reflects the rate of dilution being distributed to you rather than to others.
“`
Staking 1,000 FARM at 50% APY inflationary:
Year 1: 1,500 FARM tokens
But total supply also grew 50% — so your % ownership is unchanged
Real return ≈ 0% (minus any price impact of inflation)
“`
Real yield protocols became a major narrative in 2022 (GMX, dYdX) as a contrast to the unsustainable emission-based yields of 2021.
Compounding Frequency
Staking APY assumes reinvestment of rewards. In practice, gas costs and minimum reinvestment thresholds affect the realistic compounding frequency:
| Network | Reward Frequency | Practical Compounding |
|---|---|---|
| Ethereum (solo staking) | Every epoch (~6.4 min) | Typically monthly/quarterly |
| stETH (Lido) | Daily rebase | Continuous (automatic) |
| Cosmos chains | Per block | Typically daily via auto-compound scripts |
| Solana | Every epoch (~2.5 days) | Per epoch (automatic) |
| Protocol staking (Ethereum L2s) | Variable | Manual claim + reinvest |
Auto-compounding protocols (Yearn, Beefy, Convex) automatically reinvest rewards on behalf of depositors, converting claimed emissions into more of the underlying asset.
History
- 2020: DeFi Summer; protocols offer 100–10,000% “staking APY” — almost entirely unsustainable token emissions
- 2020–2021: Yield farming / liquidity mining becomes synonymous with “high staking APY”
- September 2022: Ethereum Merge; ~5–6% ETH staking APY drives $20B+ into staking
- 2022: Post-LUNA collapse; “real yield” narrative emerges as sustainable alternative to inflationary emissions
- 2023: Rising Fed rates (4–5% T-bill yield) create competition for on-chain staking yields; Maker’s 8% DSR briefly made DAI savings more attractive than ETH staking
- 2024–2025: ETH staking APY stabilizes ~3–4% as total staked ETH surpasses 30% of supply; real yield protocols become standard expectation
