Rampant oil consumption in Middle East nations is undermining their energy export economies and subsidy reform is desperately needed, Jim Krane argues in his new book "Energy Kingdoms: Oil and Political Survival in the Persian Gulf."
On this week's Capitol Crude, Krane talks about the global oil market's shifting fundamentals, the changing role of spare capacity and US-Saudi ties in the age of shale.
Krane is an energy studies fellow at Rice University's Baker Institute for Public Policy.
