About 74% of this 4.51% APY is decaying token emissions. The real fee yield is ~1.17%. This pool is short volatility — fees stop covering impermanent loss if CRVUSD-WETH-CRV diverges more than ±36%.
Real fee/staking yield: 1.17% · token emissions: 74% of the headline.
Break-even fact: a ±36% move in CRVUSD-WETH-CRV erases a full year of the fees you actually keep (~1.17%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
