OPEC

Organization of the Petroleum Exporting Countries is an intergovernmental organization of 14 nations as of May 2017, founded in 1960 in Baghdad by the first five members (Iran, Iraq, Kuwait, Saudi Arabia, Venezuela), and headquartered since 1965 in Vienna. As of 2016, the 14 countries accounted for an estimated 44 percent of global oil production and 73 percent of the world’s “proven” oil reserves, giving OPEC a major influence on global oil prices that were previously determined by American-dominated multinational oil companies.
