Corn Fed, Margin Tested: The Ethanol Trade Heads Back to the Field

• 1st Topic of the Week: Corn’s rally to a 2026 high this week is offsetting nitrogen’s acreage penalty, improving 2027 economics for corn acreage, ammonia demand, and ethanol feedstock availability.
• 2nd Topic of the Week: Hydrogen projects can monetize policy, captive demand, and ammonia logistics before merchant markets deepen, making market design potentially as consequential as production cost.
• Additionally, transition markets are separating growth from value creation as delivery economics determine whether new capacity, lower carbon intensity, and better technology produce durable returns.
