This study examines the repercussions of changes in commodity markets on the economies of tropical African countries. The gradual weakening of primary commodity prices that has been noticeable since 1954 continued into the early months of 1956. While not all primary commodities showed the same downward trend in 1957, the terms of exchange between primary commodities and manufactured goods became progressively less favourable for primary producers, owing to the continuing rise of the price index of manufactures in international trade.
