You're being paid 14.6% to absorb price risk. Only ~14.6% of it is real fees — and they stop covering impermanent loss if GRAM-USD₮ diverges more than ±217%.
Real fee/staking yield: 14.6% · token emissions: 0% of the headline.
Break-even fact: a ±217% move in GRAM-USD₮ erases a full year of the fees you actually keep (~14.6%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
