About 97% of this 12.1% APY is decaying token emissions. The real fee yield is ~0.41%. This pool is short volatility — fees stop covering impermanent loss if CRV-CVXCRV diverges more than ±20%.
Real fee/staking yield: 0.41% · token emissions: 97% of the headline.
Break-even fact: a ±20% move in CRV-CVXCRV erases a full year of the fees you actually keep (~0.41%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
