Oil prices have been floating around $90 a barrel for weeks, but now, the turmoil in Egypt has pushed the price up.

Louise Story, Wall Street and finance reporter for The New York Times explains the mechanisms behind such a rise: is it just fear? Shibley Telhami, Anwar Sadat Professor for Peace and Development at the University of Maryland helps contextualize the change in oil prices.
