Cocoa: A Structural Break, Not a Bad Harvest

1What actually broke

Three slow variables, not one bad season. Cocoa swollen shoot virus - incurable, spread by mealybugs, fatal to trees over a few years - has infected large tracts of Ghanaian and Ivorian farmland. The tree stock is old: cocoa yields peak in a tree's second decade and much of West Africa's was planted in the 1990s and 2000s. And both governments set fixed farmgate prices that, through the entire pre-2023 period, paid farmers a fraction of world prices - so nobody could afford to replant.

Layer weather (El Nino stress in the 2023-24 season) and disease-hit harvests on top of that base and the market discovered the true elasticity of supply: near zero on any horizon shorter than the five years a new tree needs.

2Why it does not mean-revert quickly

Higher prices are now reaching farmers - both governments raised farmgate rates substantially - and replanting has economics for the first time in a generation. But the pipeline is biological: seedling to meaningful yield is roughly four to five years, and swollen shoot removal means cutting income-producing trees today for income in 2030. Expansion elsewhere (Ecuador, Brazil, Vietnam) is real and growing but starts from a small base.

That is the structural case for a higher trading range with violent harvest-by-harvest swings - which is what the market has printed since 2024. We flag below that we cannot verify this week's exact price; the regime, not the tick, is the claim.

3Who pays

Chocolate makers bought themselves time with hedges that have been rolling off ever since. Hershey (HSY) and Mondelez (MDLZ) have both reported the squeeze through gross margin and pricing actions; the playbook is shrinkflation, reformulation toward less cocoa, and price. Barry Callebaut, the Swiss-listed processor that makes much of the world's industrial chocolate, sits in the middle of the chain passing costs through with a lag.

The demand-side tell to watch: cocoa grind statistics (quarterly, from regional associations) - the cleanest read on whether pricing is finally destroying demand.

4The honest uncertainty

This is a commodity where the data is genuinely bad: crop forecasts from two governments with fiscal stakes in the answer, disease extent surveyed irregularly, and smuggling between the two countries distorting both sets of export numbers whenever their farmgate prices diverge. Anyone quoting West African supply to three significant figures is decorating. The falsifier for the structural case: two consecutive surplus seasons with grind holding - if that prints, this was weather after all.

Sources and method

Compiled from public filings, government and agency data and trade press, cross-checked against our desks where they overlap. Supply shares and lead times in private industrial chains are estimates, are labelled as estimates, and the ones we could not verify this week are under what we do not know rather than asserted. The lines below are the factual spine.

• Cote d'Ivoire and Ghana produce roughly 60% of world cocoa (ICCO)
• Futures traded near $2,500/t for the decade to 2023, then peaked above $12,000/t in 2024 (exchange data)
• New cocoa trees need ~4-5 years to meaningful yield; swollen shoot is incurable and requires removal (agronomy literature)

Underlying sources

• ICCO statistics and regional grind data
• Ghana Cocobod / Conseil du Cafe-Cacao farmgate price announcements
• Hershey and Mondelez earnings disclosures on cocoa costs
• Agronomy literature on cocoa swollen shoot virus and tree age-yield curves
