El Niño Pushes Commodity Markets to Breaking Point – African Agriculture and Food Security Face Critical Threat
By Mpho Tumelo Modise | EZA News
Global commodity markets are registering the accumulated pressure of an El Niño weather pattern that is developing with an intensity and persistence that agricultural economists are describing in unusually stark terms – and for sub-Saharan Africa, whose food security is structurally exposed to rainfall variability in ways that more technically sophisticated agricultural systems are not, the implications are being examined with urgency.
The commodities most directly affected span the staple food basket that feeds hundreds of millions of people across the continent: maize, wheat, soybean, and the range of secondary grains and legumes that fill the nutritional gap between subsistence cultivation and market access. Price pressures in these commodities do not move in isolation – they propagate through supply chains, feed into inflation figures that central banks are already managing under pressure, and manifest at the household level as reduced meal frequency and nutritional diversity, particularly in the lower income quintiles where food expenditure constitutes the majority of household spending.
South Africa sits within this threat environment in a specific way. As both a significant regional food producer and a country with its own El Niño vulnerability – particularly in the maize belt of the Free State, North West, and Mpumalanga – the twin pressures of reduced domestic production and elevated import costs for what it cannot produce create a food security stress that moves across income levels. Middle-income households adjust their grocery baskets. Lower-income households face harder choices.
The commodity market pressure also intersects with the agricultural sector’s existing exposure to infrastructure dysfunction. Transnet’s logistics performance has been a constraint on South African agricultural exports and imports throughout 2025 and into 2026 – an additional friction cost that sits on top of the weather-driven production and price pressures now being amplified by El Niño. The combination is being watched with concern by food systems analysts across southern Africa.
Mitigation requires coordinated action on multiple fronts: social protection systems calibrated to respond to food price shocks, investment in agricultural resilience infrastructure, and the kind of regional food systems cooperation that the African Continental Free Trade Area theoretically enables but has not yet delivered at the operational level required. The window to act before the worst of the El Niño impact lands is narrowing.
