Thirteen Firms, One Agreement

Who controlled Gold Coast cocoa in 1937, according to the commission sent to investigate it, and why its two headline numbers, 98% and 94%, are so often confused.

Based on the Nowell Commission’s report, Cmd. 5845 (1938), paragraphs 28–31. Where the report is silent, this piece says so.

In the 1936/37 season almost the whole cocoa crop of the Gold Coast, today’s Ghana, left the country through thirteen European firms. In 1937 twelve of them signed a Buying Agreement that fixed the prices they would pay farmers and shared out the crop between them in quotas. Farmers answered with a hold-up that ran from October 1937 to April 1938, and London sent a commission of inquiry, chaired by William Nowell, to find out what had gone wrong.

The Commission’s report, published in September 1938 as Command Paper 5845, is still the best source for who those firms were. Ghana’s cocoa board descends from its main recommendation. This explainer sets out what the report says, and what it doesn’t.

Two numbers that are easily confused

The report gives two shares, and they measure different things.

Statement What the report says
Thirteen European firms shipped about 98% of Gold Coast cocoa exports in 1936/37 Correct
Twelve of the thirteen signed the Buying Agreement Correct
The one firm that did not sign shipped “slightly under 4 per cent” Correct
So the signatories held about 94% of exports Correct, by subtraction
“Thirteen firms controlled 94%” Wrong. Thirteen firms held 98%; the twelve signatories held 94%

The slip is small in size and large in meaning. Ninety-four per cent is the share of the crop inside the cartel. Ninety-eight per cent is the share held by the concentrated tier of buyers as a whole. The first number is about collusion; the second is about concentration. Both are worth keeping, because they support different arguments.

The thirteen firms

Merchant firms: all ten signed

Firm Nationality or group Note
United Africa Company British (Unilever) The report calls it “by far the most important shipper”, but gives no percentage
G. B. Ollivant British Listed as a separate signatory; see below on its ownership
John Holt & Co. (Liverpool) British
Paterson, Zochonis & Co. British (Manchester) Later PZ Cussons
Compagnie Française de l’Afrique Occidentale (CFAO) French
Société Commerciale de l’Ouest Africain (SCOA) French
Union Trading Company (UTC) Swiss Descended from the Basel Mission’s trading arm
Swiss African Trading Company Swiss Gold Coast only; not in the Nigerian trade
Busi & Stephenson British Gold Coast only
W. Bartholomew & Co. British Gold Coast only

Chocolate and food manufacturers: two of three signed

Firm Signed? Note
Cadbury Brothers Yes Bought “in association with Messrs. J. S. Fry and Sons”: one buying operation under two names
J. Lyons & Co. Yes
English & Scottish Joint Co-operative Wholesale Society No The only firm that stayed out, with slightly under 4% of exports

Ten merchants plus three manufacturers makes thirteen firms, and twelve signatories.

The hold-up, and what came of it

The farmers’ response was collective and long. From October 1937 to April 1938 farmers, brokers, chiefs, market women and transport workers refused to sell cocoa and boycotted European goods. It was a Gold Coast event: the Agreement also covered Nigeria, but the report records no serious agitation against it there.

The Commission recommended taking the buying of the crop out of the firms’ hands and giving it to what it called a “monopsonistic farmer’s co-operative”. The idea arrived by an indirect route. During the Second World War the West African Produce Control Board bought the crop, from 1940 to 1946. In 1947 the Gold Coast Cocoa Marketing Board replaced it, and today’s Ghana Cocoa Board (COCOBOD) descends from that board. The single state buyer exists because a handful of private buyers once controlled the crop.

Nigeria

The Nigerian trade was in the hands of the same merchant firms, except Swiss African Trading, Busi & Stephenson and W. Bartholomew, plus:

  • G. L. Gaiser (Hamburg)
  • Witt & Busch
  • C. Zard
  • Cocoa Manufacturers Ltd
  • English & Scottish Joint Co-operative Wholesale Society

The report gives no firm count or percentage shares for Nigeria. The Gold Coast figures should not be assumed to carry over.

Why “thirteen firms” understates the concentration

The list was short partly because the trade had already been consolidated. The United Africa Company was itself formed in 1929 by merging the Niger Company, which Lever Brothers had bought in 1920, with the African and Eastern Trade Corporation, which had absorbed older Gold Coast trading houses such as Miller Brothers and F. & A. Swanzy. Counting companies in 1937 counts fewer independent buying decisions than it seems to.

Then and now

The parallel with today is close in one respect and different in another. In 2026 about 20 of Ghana’s 62 registered licensed buying companies are active, and five backed by international traders account for roughly 60% of the cocoa bought inside the country. That is concentration again.

The mechanism is not the same. In 1937 the firms set the price. Today the state sets the farmgate price and buyers take it; their leverage comes from having money to finance the crop when the state and local banks don’t. The Arithmetic Doesn’t Close sets out why that matters this season.

What the report does not tell us

  1. Each firm’s share. The report names the United Africa Company as by far the largest shipper but publishes no table of shares by firm. Any claim that it held “40%” or a similar figure does not come from this source and needs its own.
  2. Who owned G. B. Ollivant in 1937. A secondary source says the United Africa Company bought Ollivant in 1933. If that is right, two of the thirteen “firms” were one group, and Unilever’s share of the 98% was larger than the list suggests. The report lists them separately without comment. I have not found a company-history source that settles it.
