About 97% of this 5.13% APY is decaying token emissions. The real fee yield is ~0.17%. This pool is short volatility — fees stop covering impermanent loss if USDC-USG diverges more than ±12%.
Real fee/staking yield: 0.17% · token emissions: 97% of the headline.
Break-even fact: a ±12% move in USDC-USG erases a full year of the fees you actually keep (~0.17%). Whether that move happens is up to the market — but any emissions inflating the headline will fade regardless.
