Communications Forum: The Changing Nature of the World Bulk Trades Available to Purchase

Since 1962 the world trades in bulk commodities as a whole have undergone two great changes: a large increase in the volume, and a large increase in the distance of the average route. In these years, trade in the five main dry bulk commodities doubled in tonnage, and in crude oil trebled in tonnage. During the same period, the length of the average route for the former rose from 3,400 miles to 4,650 miles, and for the latter from 4,500 miles to 6,750 miles. In short, three to five times as much ship capacity was required in 1973 as in 1962.
