About 94% of this 10.9% APY is decaying token emissions. The real fee yield is ~0.70%. This pool is short volatility — fees stop covering impermanent loss if WETH-USDC diverges more than ±27%.
Real fee/staking yield: 0.70% · token emissions: 94% of the headline.
Break-even fact: a ±27% move in WETH-USDC erases a full year of the fees you actually keep (~0.70%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
