What SIMRO data reveals about onion and rice price seasonality

What SIMRO data reveals about onion and rice price seasonality

Farm prices don’t rise at random: they follow cycles. By compiling SIMRO readings on rice and onion, a clear pattern emerges — and understanding it already means selling better. Here’s what the data reveals about seasonality and regional gaps.

Onion: a wide gap between harvest and lean season

It’s the most volatile chain. At harvest (often February to April depending on the area), supply is abundant and prices drop; in the lean season (around November-December), scarcity sends them soaring. A few bulb onion readings (price per kg, FCFA):

Market High supply (Feb–Apr 2026) Lean season (Nov–Dec 2025)
Bambili (North-West) ≈ 300 ≈ 700
Bamenda Food Market ≈ 500 ≈ 1,000
Mawa-Mozogo (Far North) ≈ 100–150 ≈ 200
Indicative SIMRO readings. Wide gaps by season and region.

Reading: on urban markets, the price can double between harvest and lean season. Selling everything at harvest often means selling at the worst time.

Marked regional gaps

Geography matters as much as season. In the Far North production basins (Mawa-Mozogo…), onion stays cheap. On urban and North-West markets (Bamenda…), driven by demand and transport, it’s worth two to three times more. Hence a simple rule: the price depends on when and where.

Rice: steadier, but worth watching

Rice is less volatile than onion: the imported share and the ability to store smooth variations across the year. Gaps mostly play out between local and imported rice and between regions. The logic stays the same: follow the trend rather than react to a one-off price.

What it means in practice

  • Producers: avoid selling everything at harvest; store and stagger sales towards the lean season when possible.
  • Traders: arbitrage between markets (buy in production zones, sell in demand zones) while covering transport.
  • Processors: buy at peak supply, when raw material is at its lowest.

Frequently asked questions

When is onion cheapest?

At peak harvest (often February-April), when supply is abundant. Prices then climb until the lean season (November-December).

Why is onion pricier in Bamenda than in the Far North?

Because the main production basins are in the North; towards urban markets, transport and demand push the price up.

Does rice follow the same seasonality?

Less strongly: the imported share and storage smooth variations. Watching trends is still useful.
