This week, Bloomberg energy and commodity reporters Javier Blas and Jack Farchy join Ben Cahill (CSIS) for a discussion of their new book, The World for Sale: Money, Power and the Traders Who Barter the Earth’s Resources. Their discussion focuses on the influential role that commodity traders have played in global oil markets over the past four decades and looks ahead to how the commodities business may need to respond to new demands of the global energy economy.
