In 1979, Dan Morgan, a journalist with the Washington Post, wrote Merchants of Grain, a definitive history of the international grain trade. In the 40 years since Dan's book was published the grain markets have changed almost beyond recognition. So too have the merchants of grain. Once shadowy figures, grain merchants have now come out of the shadows. Almost everything that you eat or drink today will contain something bought, stored, transported, processed, shipped, distributed or sold by one of the seven giants of the agricultural supply chain. The media often refers to them as the ABCD group of international grain-trading companies, with ABCD standing for ADM, Bunge, Cargill and Dreyfus. The acronym, though, ignores the other three giants of the food supply: Glencore, COFCO International and Wilmar. Together, they handle 50 percent of the international trade in grain and oilseeds. In this book's series of exclusive and unprecedented interviews, CEOs and senior traders from these seven giants describe in their own words how the agricultural markets are changing, and how they are adapting to those changes. Accompanying text explains how grain trading works, what grain traders do, and the journey that your food takes before arriving on your plate.This is the inside story of the grain market and of the seven companies at the centre of the world's food supply.
