The Organization of Petroleum Exporting Countries (OPEC) is an international alliance comprised of 13 member countries.
In alphabetical order, the 13 OPEC members are Algeria, Angola, Congo, Equatorial Guinea, Gabon, Iran, Iraq, Kuwait, Libya, Nigeria, Saudi Arabia, United Arab Emirates and Venezuela.
Overall, OPEC members shipped US$421.9 billion worth of crude oil around the globe in 2021. That dollar amount represents an -8% decline from $458.8 billion in 2017, but a 23% acceleration compared to $343.1 billion during 2020.
As a cartel, OPEC countries’ ability to collude and influence oil prices has weakened noticeably over the past 5 years.
In 2017, OPEC nations collected well over half (54.7%) of revenues from globally exported crude oil. Five years later, OPEC’s percentage share of the world total had dwindled to 49.7% for 2021.
