About
The Organization of the Petroleum Exporting Countries (OPEC) is a permanent intergovernmental organization established in 1960 to coordinate and unify petroleum policies among its member nations. Headquartered in Vienna, Austria, OPEC operates as an international cartel that influences global oil prices by setting production targets for its members. As of 2022, OPEC accounted for 38 percent of the world's oil production and held an estimated 79.5 percent of proven global oil reserves, with the Middle East alone containing 67.2 percent of OPEC's total reserves.
OPEC's membership has evolved since its founding, with 11 current members as of the latest data: Algeria, Republic of the Congo, Equatorial Guinea, Gabon, Iran, Iraq, Kuwait, Libya, Nigeria, Saudi Arabia, and Venezuela. In 2016, the organization expanded its influence through the Declaration of Cooperation, creating the OPEC+ framework that includes additional non-OPEC producers such as Russia, Mexico, and Kazakhstan. This broader alliance has allowed OPEC to coordinate production cuts with major non-member oil states, amplifying its impact on global energy markets.
The organization has been a subject of intense scrutiny and controversy, particularly from Western governments. U.S. presidents from Gerald Ford to Donald Trump have publicly criticized OPEC as a cartel that artificially inflates oil prices, and the U.S. government has investigated potential antitrust violations. Despite these challenges, OPEC has remained a central force in the global energy landscape, adapting to shifts in supply and demand while maintaining its core mission of securing stable revenues for member states.
Mission
OPEC's mission is to coordinate and unify the petroleum policies of its member countries, ensuring the stabilization of oil markets to secure an efficient, economic, and regular supply of petroleum to consumers, a steady income to producers, and a fair return on capital for those investing in the petroleum industry. The organization also upholds the principle, enshrined in its 1968 Declaratory Statement of Petroleum Policy, that every nation has complete sovereignty over its natural resources for national enrichment and development.
History
OPEC was founded at the Baghdad Conference held in Iraq from September 10 to 14, 1960, with five founding members: Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela. The immediate trigger was the decision by major Western oil companies, the so-called Seven Sisters, to reduce posted prices for Middle Eastern crude oil in August 1960, cutting into the revenues of oil-exporting nations. The conference produced a formal statute that took effect in January 1961, establishing OPEC as a permanent intergovernmental body.
The organization's early years were marked by rapid expansion. Qatar joined in 1961, followed by Libya and Indonesia in 1962, and the United Arab Emirates in 1967. Algeria became a member in 1969, Nigeria in 1971, Ecuador in 1973, and Gabon in 1975, bringing total membership to 13 by the mid-1970s. Initially headquartered in Geneva, Switzerland, OPEC moved its offices to Vienna, Austria, on September 1, 1965, where the Secretariat remains today.
OPEC's influence grew substantially during the 1970s as member states nationalized their oil industries, shifting control away from Western multinationals. The 1973 oil embargo, led by Arab members of OPEC against countries supporting Israel during the Yom Kippur War, demonstrated the organization's ability to disrupt global markets and quadruple oil prices. However, the 1980s saw a collapse in oil prices due to increased non-OPEC production and internal disagreements over quotas, weakening OPEC's grip on the market. In response, the organization developed a system of production quotas and price bands to stabilize revenues.
A major turning point came in 2016 with the Declaration of Cooperation, which created the OPEC+ framework. This alliance brought in 11 non-OPEC producers, including Russia, to coordinate production cuts more effectively. The partnership proved critical during the 2020 COVID-19 pandemic, when OPEC+ implemented historic production reductions to counter plummeting demand. As of 2025, OPEC continues to adapt, with Secretary-General Haitham al-Ghais pushing for nuanced discussions around the role of fossil fuels in the energy transition.
