An analysis argues soybean oil prices have often led crude oil moves because vegetable oil markets are small and sensitive to shifts in crude. The key link is biofuel mandates in 64 countries, where refiners buy more or less vegetable oil depending on crude supply and demand.
Biofuel-linked demand means crude price swings transmit to vegetable oil and soymeal-linked oilseed prices, so feed buyers should watch crude as a leading indicator.
