You're being paid 15.9% to absorb price risk. Only ~15.9% of it is real fees — and they stop covering impermanent loss if UNI-USDC diverges more than ±235%.
Real fee/staking yield: 15.9% · token emissions: 0% of the headline.
Break-even fact: a ±235% move in UNI-USDC erases a full year of the fees you actually keep (~15.9%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
