About 98% of this 9.99% APY is decaying token emissions. The real fee yield is ~0.21%. This pool is short volatility — fees stop covering impermanent loss if MUSD-CRV2POOL diverges more than ±14%.
Real fee/staking yield: 0.21% · token emissions: 98% of the headline.
Break-even fact: a ±14% move in MUSD-CRV2POOL erases a full year of the fees you actually keep (~0.21%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
