The seven OPEC+ countries (Saudi Arabia, Russia, Iraq, Kuwait, Kazakhstan, Algeria, and Oman) have agreed to raise their crude oil output by 188 kb/d from the additional voluntary adjustments announced in April 2023 (OPEC+ press release, 03/05/2026).
For June 2026, the aggregate target production levels and increments for these countries are set at: Saudi Arabia (10.3 mb/d, +62 kb/d), Russia (9.8 mb/d, +62 kb/d), Iraq (4.4 mb/d, +26 kb/d), Kuwait (2.6 mb/d, +16 kb/d), Kazakhstan (1.6 mb/d, +10 kb/d), Algeria (989 kb/d, +6 kb/d), and Oman (826 kb/d, +5 kb/d).
The announcement comes after a major setback for the group with the United Arab Emirates (UAE) deciding earlier in May 2026 to withdraw from the Organisation of the Petroleum Exporting Countries (OPEC and OPEC+) after 59 years (KEI, 30/04/2026).
The UAE is the largest oil producer ever to leave OPEC, having produced about 3.4 mb/d, or roughly 3% of global crude supply, before the US–Israeli war on Iran and the resulting shipping disruptions in the Strait of Hormuz. If maritime traffic returns to pre‑war levels, the country could potentially ramp up output to its full 5 mb/d capacity for crude oil and liquids.
In April 2026, the organization had already agreed to increase its crude oil production by 206 kb/d, an adjustment that entered into force in May 2026 (KEI, 08/04/2026). Of this 206 kb/d increase, 18 kb/d were to be produced by the UAE and 188 kb/d by the other seven OPEC+ countries.
