White maize market trends, 2021 to 2025

Southern Africa relies on rainfed maize, and South Africa anchors the region’s tradable surplus and its price discovery. The 2024 drought exposed that concentration: northern harvests collapsed, import needs rose and SAFEX white maize reached record territory. Procurement, production and policy decisions now have to be built around volatility rather than average conditions.

SAFEX repriced scarcity before the harvest recovered

The annual nearby white maize price rose from R3,317 a tonne in 2021 to R5,103 in 2024. It peaked near R7,000 in early 2025, then eased as South Africa’s crop recovered, but the 2025 average of R4,558 was still 37% above 2021. The forward curve now carries both local crop expectations and regional export demand.

Regional output lost its 2021/22 cushion

Combined production across South Africa, Zambia, Malawi, Mozambique and Zimbabwe peaked at 28.9 million tonnes in 2021/22. It fell to 23.8 million in 2023/24 and stayed there in 2024/25: South Africa’s rebound offset sharp drought losses in Zambia and Zimbabwe but did not rebuild the regional buffer. Availability became more dependent on South African surplus and offshore imports.

Where the shock landed

South Africa supplied roughly two-thirds of the five-country crop in 2024/25. Zambia and Zimbabwe recorded their weakest harvests of the window; Malawi’s decline was steadier; Mozambique stayed a small producer with persistently low yields.

Yield, not land, is the region’s largest structural gap

South Africa averaged 5.4 to 5.9 tonnes a hectare outside the drought year, on the back of commercial seed, mechanisation and agronomy. Zambia and Malawi clustered near 2 t/ha. Mozambique and Zimbabwe stayed mostly below 1.5 t/ha, leaving their output exposed to rainfall timing and input access.

Three producers, three market roles

South Africa (17.27 Mt, 5.85 t/ha) is the regional swing supplier: deep commercial production and SAFEX price discovery. Drought cuts its export capacity; recovery restores it. Zambia (1.51 Mt, 2.21 t/ha) lost a traditional surplus to the 2024/25 drought, and input delivery, reserve purchases and export controls can amplify uncertainty. Malawi (3.00 Mt, 2.00 t/ha) runs a dense smallholder system where limited inputs and weather quickly become food-security pressure.

Zimbabwe (0.64 Mt, 0.73 t/ha) swung from 2.72 Mt to 0.64 Mt in three seasons. Mozambique (1.40 Mt, 0.88 t/ha) is held back by certified seed, fertiliser, extension and logistics, with cyclones and dry spells on top. FEWS NET estimated a 2 million tonne negative net supply for the region in MY2024/25, and South African basis, freight and export policy are what transmit SAFEX into those markets.

Five risks recur from planting to market

• Rainfall timing, heat and drought
• Fertiliser, fuel, finance and foreign exchange
• Certified seed and mechanisation
• Fall armyworm and crop disease
• Storage, power, freight and policy

Most regional maize is rainfed and, outside South Africa, mostly grown by smallholders. That makes rainfall the first-order risk, but access to finance, seed, fertiliser, machinery, storage and predictable trade rules decides how hard a weather event lands on yield and price.

What to do before the weather turns

Hedge and procure. Stagger SAFEX cover across the season, set trigger levels against import parity, basis and FX, and pre-qualify alternative origins before regional deficits appear. Raise attainable yield. Pair drought-tolerant certified seed with soil testing, timely fertiliser placement, conservation practices and targeted irrigation where the economics allow. Strengthen corridors. Use shared early-warning signals, protect storage quality, pre-clear import protocols and push for transparency on reserve releases and export restrictions.

How to read the series

Harvests cover 2020/21 to 2024/25; prices cover calendar 2021 to 2025. Total maize is used as the comparable harvest proxy because white and yellow splits are inconsistent outside South Africa. Watch rainfall onset and NDVI, the SAFEX forward curve and basis, fertiliser and FX, export restrictions, import approvals, and South African crop estimates and silo deliveries.
