Four Hundred Dollars a Tonne
Cocoa in Ghana has no market price — a state board announces one figure each October and every farmer in the country is paid it. In 2019 Ghana and Côte d'Ivoire used that monopoly to impose a $400-a-tonne premium on the entire world market, and then spent years watching buyers try to subtract it again somewhere else in the price.
Cocoa in Ghana does not have a market price. It has an announced one. At the opening of the main crop each October the Ghana Cocoa Board publishes a farmgate price in cedi per 64-kilogram bag, and that is what every farmer in the country is paid — the same figure in Ashanti as in Western North, the same for a household working two hectares as for one working twenty. Licensed buying companies collect the beans at that price and deliver them to the board, which does all of the exporting itself.
COCOBOD has been doing this since 1947, when it was set up under colonial administration as the Gold Coast Cocoa Marketing Board, and independent Ghana kept it rather than dismantling it. Most of the other producers went the other way — Nigeria, Cameroon and eventually Côte d'Ivoire liberalised their cocoa sectors across the late 1980s and 1990s, under pressure from lenders who regarded a state marketing monopoly as the textbook definition of a bad idea. Ghana held on to its. Whether that was stubbornness or foresight is a live argument, and 2019 is the year it stopped being academic.
What a single seller can do
A monopoly exporter has one power that no individual farmer will ever have: it can refuse to sell. In June 2019 Ghana and Côte d'Ivoire used it jointly. The two countries, which between them grow around 60 per cent of the world's cocoa, suspended forward sales of the 2020/21 crop outright and told buyers that sales would resume only on a new term. That term was the Living Income Differential — a flat premium of US$400 a tonne, charged on top of the futures price and the origin differential, on every tonne either country sold. The alliance behind it was not improvised in a week: the two governments had signed the Abidjan Declaration in March 2018 and set up a joint body, the Côte d'Ivoire–Ghana Cocoa Initiative, to coordinate precisely this kind of move.
Where the number came from
The four hundred was not plucked out of the air, which matters, because the usual criticism of producer cartels is that the price is whatever the cartel thinks it can get away with. The LID was reverse-engineered from a living income benchmark — an estimate of what a cocoa-farming household of a given size, working a given acreage at realistic yields, would need to earn to cover food, housing, schooling and health care at a decent standard — set against what the crop actually returned. The premium was the gap. That made it defensible in public in a way that a round number never would have been, and it put the buyers in the position of having to argue that farmers should earn less than the benchmark.
A premium is only a premium if nobody can take it back somewhere else in the price. That sentence is the entire history of the Living Income Differential.
The subtraction
Cocoa is not sold at a single number. It is sold as a futures contract plus a country differential — a discount or premium reflecting bean quality, shipment terms and how badly a particular buyer wants that particular origin. The LID sat on top of both, and the country differential was the part nobody had fixed. Within a season it fell, and then it went negative and kept going. Ghana and Côte d'Ivoire said publicly that buyers were clawing the premium back through the differential, named companies, threatened to bar their sustainability staff from farms and at one point suspended their certification programmes outright. The buyers replied that the differential reflected a genuine oversupply and that nobody had promised otherwise. Both statements can be true at once, which is why the dispute ran for years rather than being settled by an audit.
The price the farmer actually gets
Then the market did something nobody had planned for. Cocoa futures went past $10,000 a tonne in 2024, several times any recent normal, and Ghana was largely unable to capture it — because a board that sells forward has, by definition, already sold. Much of the crop had gone a season or more in advance at a fraction of what it was suddenly worth, and the 2023/24 harvest came in far short even of what had been contracted. The mechanism that shelters farmers from a crash is the same mechanism that shelters them from a boom, and 2024 was the year Ghanaian farmers found out which half they were in. COCOBOD raised the farmgate price repeatedly to close the gap, and the gap that mattered was not with the world price at all but with the price across the border: when a Ghanaian farmer can get more per bag in Côte d'Ivoire or Togo, beans walk over the frontier at night, and no announced price survives contact with a footpath.
What is eating the crop
Underneath the pricing argument is a slower one about whether there will be a crop to price. Cacao swollen shoot virus disease is spread by mealybugs, has no cure, and the only treatment is cutting out infected trees and replanting — after which the new trees take years to bear anything. A great deal of Ghana's cocoa is also simply old, planted decades ago and past its productive peak, on farms whose owners are themselves ageing and whose children have largely gone to Kumasi or Accra. And in the western cocoa districts the land is competing with galamsey, unlicensed small-scale gold mining, which pays a farmer more for his plot in a week than the plot will earn him in a decade and leaves behind ground that grows nothing.
None of this is visible from the N10. What you see driving north out of Takoradi is ordinary — low trees under taller shade, beans drying on raffia mats at the roadside, turned by hand with a wooden rake, sacks stacked outside a buying company shed with a painted logo. It looks like agriculture, because it is. What it does not look like is the thing it actually is, which is a country that decided it would rather set the price of its own principal export than accept one, and has been finding out ever since exactly how far that decision can be made to hold.
