There have been some challenges to OPEC's influence over the years, often resulting in internal divisions, and a global push towards cleaner energy sources and a move away from fossil fuels could ultimately diminish its dominance.
OPEC became OPEC Plus in 2016 after joining hands with 10 of the world's major non-OPEC members, including Russia.
OPEC+ Plus represents around 40% of world oil production and its main objective is to regulate the supply of oil to the world market. The leaders are Saudi Arabia and Russia, which produce around 10 million barrels per day (bpd) of oil each.
OPEC member states' exports make up around 60% of global petroleum trade. In 2021, OPEC estimated that its member countries accounted for more than 80% of the world's proven oil reserves.
Because of the large market share, the OPEC decisions affect oil prices. Its members meet regularly to decide how much oil to sell on global markets.
As a result, when they lower supply when demand falls, oil prices tend to rise. Prices tend to fall when the group decides to supply more oil to the market.
On April 02, 2023 OPEC Plus agreed to deepen crude oil production cuts to 3.66 million barrels per day (bpd) or 3.7% of global demand, until the end of 2023, which helped to push up oil prices by about US$9 a barrel to above US$87 per barrel over the following days, but Brent prices have since lost those gains.
During the 1973 Arab-Israeli War, Arab members of OPEC imposed an embargo against the United States in retaliation for its decision to re-supply the Israeli military, as well as other countries that supported Israel. The embargo banned petroleum exports to those nations and introduced cuts in oil production.
The oil embargo pressured an already strained US economy which had grown dependent on imported oil. Oil prices jumped, causing high fuel costs for consumers and fuel shortages in the United States. The embargo also brought the United States and other countries to the brink of a global recession.
In 2020, during COVID-19 lockdowns around the world, crude oil prices slumped. After that development, OPEC Plus slashed oil production by 10 million barrels a day, which is equivalent to around 10% of global production, to try to bolster prices.
The current members of OPEC are: Saudi Arabia, United Arab Emirates, Kuwait, Iraq, Iran, Algeria, Angola, Libya, Nigeria, Congo, Equatorial Guinea, Gabon and Venezuela.
Non-OPEC countries in the global alliance of OPEC Plus are represented by Russia, Azerbaijan, Kazakhstan, Bahrain, Brunei, Malaysia, Mexico, Oman, South Sudan and Sudan.
