You're being paid 6.45% to absorb price risk. Only ~6.45% of it is real fees — and they stop covering impermanent loss if RAY-USDC diverges more than ±109%.
Real fee/staking yield: 6.45% · token emissions: 0% of the headline.
Break-even fact: a ±109% move in RAY-USDC erases a full year of the fees you actually keep (~6.45%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
