(Bloomberg) — Cocoa’s stunning rise and its equally remarkable slump are beginning to shake up the longstanding way of doing business in West Africa, the region that supplies the bulk of the world’s beans.

Ghana, the No. 2 producer, kicked off a process this week to loosen the tight state regulation of domestic prices. Discontent is simmering in top grower Ivory Coast as well, with traders holding off on buying beans for the upcoming mid-crop harvest in hopes of lower costs.

Cocoa sales in the two countries — which grow more than half of global supply — have long been controlled by government regulators that fix farmer pay and market the beans. It’s a structure intended to shield growers, many of whom are smallholders, from the volatility of crop markets.

But as futures surged to an all-time high in 2024, and crashed more than 70% thereafter, the system has made it difficult both for farmers to benefit from the rally and traders to remain profitable on the decline. With warehouses and ports clogged with unsold beans, and cocoa prices still falling, that’s straining the supply chain and sparking changes that could alter the global cocoa market for years to come.

Ghana’s move “is being interpreted as a more sustainable funding solution,” said Andrew Moriarty, senior cocoa manager at crop research firm Expana. “This does potentially remove some risk from supply disruptions looking ahead.”

West Africa has long dominated the cocoa industry, with tropical climes well suited for producing the chocolate ingredient. But a mix of crop disease and increasingly extreme weather has weighed on crops, catalyzing a rally that pushed futures to nearly $13,000 a ton in 2024 — quadruple the long-term norm.

Regulators, who sell most of the crop months before it’s collected, couldn’t fulfill all the contracts in that year, rolling some to the next harvest. And chocolate manufacturers were left searching for ways to contain costs. Some tweaked recipes, adding in nuts or cookies, or swapped cocoa butter for cheaper vegetable-oil substitutes.

The cratering demand, coupled with improving production, caused the market to correct quickly. Commodities brokerage Marex Group estimates a 400,000-ton global surplus in the current season, which would be the biggest in International Cocoa Organization data going back to the 1980s.
