A direct cross-commodity relationship exists between energy prices and row crops, specifically corn and soybeans.
Approximately 40% of the US corn crop is used for ethanol, producing about 15 billion gallons annually blended into the gasoline supply via the Renewable Fuel Standard.
Rising gasoline prices improve ethanol blending economics, causing refiners to compete more aggressively for corn, which directly influences CBOT corn futures prices.
Soybean oil is the dominant feedstock for the US biodiesel and rapidly expanding renewable diesel sector.
The link between soybean oil and diesel has intensified sharply in recent years, driven by major refiners pouring capital into renewable diesel capacity.
Soybean oil has effectively transitioned from a purely agricultural commodity to an energy commodity, competing directly with petroleum diesel at the refinery level.
The corn-ethanol linkage is a long-standing structural relationship, while the soy-diesel link is a more recent and accelerating dynamic.
These connections mean energy market movements now have a more immediate and consequential impact on agricultural commodity pricing and demand.
