The escalation of conflict in the Middle East in 2026 and the disruptions affecting major maritime chokepoints, particularly the Strait of Hormuz and the Bab el-Mandeb/Red Sea corridor, threaten global food security through higher energy, fertilizer, and shipping costs. We argue that the shock is more structural than previous crises because it simultaneously affects core agricultural inputs and trade routes, unlike the 2022 price spike in the wake of the Russian invasion of Ukraine, which primarily caused temporary supply shortages. This has specially severe consequences for import-dependent economies in the Gulf area, Africa, and other low- and middle-income countries (LMICs). While energy price shocks can be transmitted relatively quickly to food markets through immediate changes in production and transportation costs, shipping cost and fertilizer price shocks tend to operate with longer adjustment lags because they propagate through physical supply chains and agricultural production processes. Prolonged energy market disruptions stemming from conflict around the Strait of Hormuz, together with tensions affecting Bab el-Mandeb, or future disruptions from (geo)political conflicts, entail the risk of trade policy responses and further market disturbances that could exacerbate the ongoing crisis. We highlight that rising prices for energy, shipping, and food are placing an immense strain on LMICs already burdened by heavy debt, limited access to finance, and inflationary pressure, with implications for food security and hunger.
