El Niño and Cocoa: Drought, Disease, and Chocolate Price Shocks
Published: July 7, 2026 · 8 min read
TL;DR — Cocoa Takes a Hit Every Time
Every major El Niño since 1960 has reduced global cocoa output. West Africa — Côte d'Ivoire and Ghana, 60%+ of world cocoa — gets drier harmattan winds and reduced rainfall. Indonesia, the #3 producer, also dries out. On top of drought stress, irregular weather triggers black pod disease and swollen shoot virus. With cocoa prices already near historic highs from structural supply issues, a strong 2026-27 El Niño could push them higher still.
West Africa: Where Most Chocolate Starts
Côte d'Ivoire and Ghana produce over 60% of the world's cocoa. The crop depends on two rainy seasons — the major season (April-July) and minor season (September-November) — with the main harvest from October to March. El Niño tends to suppress the minor rainy season and intensify the December-February harmattan — the dry, dusty wind from the Sahara.
A strong harmattan during cocoa harvest is bad news. The dry winds stress trees, reduce pod size, and can interrupt the drying process for harvested beans. The 2015-16 El Niño intensified the harmattan enough to cut West African production by an estimated 5-10%, contributing to a global cocoa deficit of nearly 200,000 tonnes.
| Event | Côte d'Ivoire | Ghana | Indonesia | Global Deficit/Surplus | Price Impact |
|---|---|---|---|---|---|
| 1982–83 | -10% | -15% | -10% | -150k tonnes | Cocoa +50% |
| 1997–98 | -8% | -5% | -20% | -120k tonnes | Cocoa +30% |
| 2015–16 | -5% | -10% | -15% | -196k tonnes | Cocoa +20-30% |
| 2023–24 | -20%* | -25%* | Stable | -400k+ tonnes | Cocoa +200% (structural + weather) |
*The 2023-24 West Africa numbers reflect a combination of El Niño harmattan, swollen shoot virus, and structural issues (aging trees, low farmer incomes). El Niño wasn't the sole driver, but it amplified an already stressed system.
Disease: The El Niño Multiplier
Cocoa is vulnerable to two major diseases that El Niño conditions promote. Black pod disease (Phytophthora) thrives in the irregular wet-dry cycles that El Niño creates — too dry for too long, then sudden heavy rain, and the fungal spores explode. Swollen shoot virus, transmitted by mealybugs, also spreads more aggressively when trees are stressed. Trees weakened by drought are sitting ducks for both.
2026-2027 Outlook
Cocoa markets enter the 2026-27 El Niño already in crisis mode. Prices hit record highs in 2024-2025 due to West African production collapses (structural deficits, not just weather). A strong El Niño that further reduces West African output would compound an already severe supply shortage. Chocolate manufacturers have been drawing down stockpiles and reformulating products (smaller bars, lower cocoa content). The 2026-27 El Niño will test whether that strategy holds or whether consumers face another round of price hikes.
Global Cocoa Production: Regional Vulnerability Map
The global cocoa market is concentrated in a handful of regions — and many of them sit directly in El Niño's crosshairs. Understanding which producing regions face what risks helps explain why prices move the way they do during El Niño events.
| Region | Share of Global Production | El Niño Impact | Risk Level |
|---|---|---|---|
| Latin America | ~30–55% | Drought in north, excessive rain in south | High |
| Southeast Asia | ~20–40% | Reduced monsoon rainfall, reservoir stress | High |
| West Africa | ~15–30% | Variable; drought risk in Sahel, wetter in Gulf of Guinea | Medium |
| East Africa | ~5–15% | Flooding risk in eastern countries, drought in south | Medium |
| South Asia | ~5–20% | Monsoon weakening, irrigation-dependent crops at risk | High |
During past strong El Niño events, cocoa prices have risen 20-80% from pre-event levels, depending on the severity of production losses and the level of global stockpiles. The 2026-2027 event enters with global food prices already elevated from the 2022-2024 cycle, meaning even moderate production disruptions could trigger outsized price responses in commodity markets.
For importing countries — particularly in the Middle East and sub-Saharan Africa — higher cocoa prices translate directly into food insecurity, import bill stress, and in extreme cases, social unrest. The 2026 event is a reminder that El Niño is never just a weather phenomenon. It's an economic one.
