The age of oil rents is over. A political and geopolitical revolution is on its way.
About twenty countries around the world are dependent on a single number: the price of oil. Some, primarily Persian Gulf states, live entirely off their oil and gas wealth. They rely on crude oil, natural gas and petroleum products for 50 percent of their Gross Domestic Product and for 70-plus percent of their budget revenue. Some 15 countries generate more than 50 percent of their export earnings from oil, gas and petroleum product sales.
