Diesel prices hit record high

# Why This Matters Record diesel prices pose an immediate threat to supply chains and consumer costs across the economy. Diesel powers roughly 70 percent of freight transportation in the United States, so sustained price spikes directly increase shipping costs for groceries, manufactured goods, and raw materials—expenses that retailers and manufacturers typically pass to consumers. The Iran situation reveals how concentrated global energy production remains; disruptions to just one region's exports can cascade through markets worldwide, making economies from Europe to Asia vulnerable to further geopolitical shocks. Industries already operating on thin margins, particularly agriculture and logistics, face operational crises if prices persist, potentially triggering layoffs and reduced service capacity that could ripple through employment and availability of essential goods.
