US dairy markets are one of, if not the most, unique and complex commodity markets. Dairy production has unique physical characteristics not found in any other agricultural commodities, including continuous production, rapidly spoiling milk inventories, and multiple derivative products with a varying ability to store over time (i.e., fresh milk vs. cheese products).
These factors, when combined with changes in seasonal demand, the impacts of variable weather conditions that can affect both production and the ability to transport that production to processors, and changes in productive herd levels that will impact supply on any given day, result in highly volatile prices for producers and cooperatives.
