Jack Farchy

Javier Blas and Jack Farchy are two of the world's best-known journalists covering energy, commodities and trading houses. They both work for Bloomberg News, where Blas is chief energy correspondent and Farchy is a senior reporter coering natural resources. Previously, they covered commodities for the Financial Times.

Blas and Farchy have interviewed most of the key figures in the commodity trading industry - in some cases, the first time the traders had ever spoken publicly. They've published the financial accounts of many of these secretive companies for the first time. And they've reported on oil, food and war from countries as diverse as Kazakhstan, Ivory Coast, and Libya.

The pair frequently appear on TV and radio as experts on commodities. Blas has been interviewed on BBC News, CNN and Al Jazeera, and Farchy regularly appears on BBC Radio 4 Today. The World for Sale is their first book.
