Cocoa shortages: what causes them
Disease, ageing trees and weather, concentrated in two countries that grow more than half the world's crop.
If you read nothing else
Two countries grow over half the world's cacao, so West African disease and ageing trees are a global supply problem — and replanting takes years to bear.
Concentration is the underlying risk
Ivory Coast and Ghana together grow well over half the world's cacao. That concentration means a problem in West Africa is a problem for global supply, with no other region large enough to absorb it.
It is a legacy of nineteenth-century transplantation rather than a natural distribution — cacao is native to the Amazon — and it is the single most important structural fact about the market.
The three current pressures
Cacao swollen shoot virus has caused sustained losses in West Africa and has no treatment once a tree is infected; control means removing trees. Black pod disease pressure rises with humidity and rainfall.
Much of the West African tree stock is ageing and past peak productivity, and replanting means several years without a crop from that land — a cost a smallholder cannot easily absorb.
Weather disruption compounds both, and climate projections suggest suitability in parts of the current growing area will decline.
What a shortage does downstream
Prices rise on the exchange first, then reach retail with a lag of months as hedges expire. Manufacturers respond by reducing pack sizes, substituting permitted vegetable fats, and reformulating toward the legal minimum cocoa content.
Craft makers are affected differently: their bean costs were already well above commodity, so the proportional rise is smaller, but they have less ability to reformulate because the bean is the product.
