Iran war fuel crisis threatens South Africa's maize harvest season

Global fuel prices have surged due to the Iran conflict, creating severe cost pressures for South African farmers entering their critical maize harvesting season in April 2026. Farmers report that elevated diesel and transportation costs are directly threatening crop yields and their economic viability. This supply chain disruption illustrates how Middle Eastern geopolitical instability cascades into food security risks across Africa, affecting global grain supplies and prices. With South Africa a major regional food producer, harvest failures could destabilize food access across southern Africa and push global commodity prices higher.
