The US agricultural belt doesn't drink Russian diesel directly. Most fuel powering tractors in the Midwest comes from domestic plants or shipments from Canada and the Gulf Coast. But the global market functions as a single pool. When Ukrainian drones disable Russian refineries, global diesel inventories dip. This spikes the 'crack spread'—the profit margin between raw crude and refined fuel.
Prices ripple outward. Farmers likely won't face empty tanks, but they will face volatile invoices. If a strike coincides with the spring planting rush, these price jumps hit harder. To hedge this, US refiners have increased throughput and diversified their sourcing. The risk isn't a total supply collapse; it's the unpredictability of the pump price. Market volatility creates a financial gamble for growers, even if the physical fuel remains available.
