You're being paid 11.3% to absorb price risk. Only ~11.3% of it is real fees — and they stop covering impermanent loss if JLP-USDC diverges more than ±171%.
Real fee/staking yield: 11.3% · token emissions: 0% of the headline.
Break-even fact: a ±171% move in JLP-USDC erases a full year of the fees you actually keep (~11.3%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
