The modern world is built on commodities - from the oil that fuels our cars to the metals that power our smartphones.

We rarely stop to consider where they have come from. But we should.

The World for Sale lifts the lid on one of the least scrutinized corners of the world economy: the billionaire commodity traders who buy, hoard, and sell the earth's resources. It is the story of how a handful of swashbuckling businessmen became indispensable cogs in global markets, enabling an enormous expansion in international trade and connecting resource-rich countries - no matter how corrupt or war-torn - with the world's financial centers. The result is an eye-opening tour through the wildest frontiers of the global economy, as well as a revelatory guide to how capitalism really works.
