In your life

Farm share of your food dollar

11.8¢of every US consumer food dollar reaches the farm (USDA, 2024)

18.5¢ of every food-at-home dollar. That's a ceiling, not a prediction: makers and stores can absorb a corn spike, or pass on more than the corn alone.

Grade A large eggs (US)

Grade A large eggs (US) costs about $2.27 a dozen in the US (August 2026, BLS).
When corn prices jump, eggs usually follows 3–5 months later.
Last time this happened: when corn futures jumped +22.3% (Feb 2012 → Aug 2012), eggs moved Jun 2012 ($1.670/doz) → Dec 2012 ($2.007/doz, +20.2%) → Jan 2013 ($1.933/doz, +15.7%) (BLS APU0000708111).
Other forces were pushing too: Egg prices also move with holiday baking demand each December, energy and transport costs, and layer-flock size — not feed corn alone.
Eggs are the measured retail leg; soda (HFCS) stays a thin leg and is not measured here.

BLS Average Price Data — 'Eggs, grade A, large, per dozen' in U.S. city average (FRED APU0000708111) Lag basis: Leibtag (2009), USDA ERS: retail egg prices respond to commodity/input cost changes in 3–5 months.

Corn is in your everyday life as your tortillas & cereal.

An importer is “critical” here by share of world corn imports; the per-exporter dependency underneath is what makes a shock travel. 2024 vintage · annual data, 1–2y lag — annual data, 1–2y lag.
