Background

OPEC is an intergovernmental organisation through which oil-producing states coordinate petroleum policy and output decisions. It was founded in Baghdad and is headquartered in Vienna. Its ministerial agreements aim to influence global crude supply, but their effect depends on each member having spare capacity and following its allocation.

The organisation also works through OPEC+, a broader arrangement that includes Russia and other non-members. Many market-moving decisions are taken by smaller voluntary-adjustment groups inside that wider forum, so an OPEC Headline does not always mean every member changed production.

The Vienna secretariat publishes communiques, monthly market reports and production data. These documents separate formal decisions from delegate reports and from the number of barrels members actually pump. OPEC's influence therefore rests on three linked factors: its assessment of demand, agreed output policy and members' ability to deliver the promised change.

Key Issues
Production policy

OPEC depends on wider coordination

On 5 July, OPEC+ approved a fourth consecutive monthly increase, adding 188,000 barrels a day to August output. The decision continued the wider group's effort to signal more supply even though members might not pump every approved barrel.

On 2 August, OPEC's own release recorded seven countries approving the same-sized adjustment for September and set 6 September for their next meeting. It did not mention the fourth-quarter pause reported earlier from delegate sources. For OPEC, the correction shows why formal communiques and actual production matter more than market expectations about its next move.

Common Questions
What is OPEC doing about Saudi Arabia's budget deficit in 2026?
Nothing directly. Saudi Arabia's fiscal breakeven is $108-111/barrel; Brent settled at $72.91 on 30 June 2026, leaving Riyadh under extreme negative carry. OPEC+ voted successive 188,000 bpd monthly increases it structurally cannot deliver, since actual group output collapsed 9.58 mbd from February levels due to Hormuz disruption.Source: OPEC secretariat / Goldman Sachs
Why did oil prices fall 30% in Q2 2026?
Brent Crude fell roughly 30% from Q2 2026 open to settle at $72.91 by 30 June, as markets priced in the easing of Hormuz supply-risk alongside OPEC+'s successive production-increase approvals. The verbal US-Iran stand-down on 29 June added only +1.3% on the day, suggesting most of the war-risk premium had already been unwound.Source: Lowdown / Brent market data
How will the UAE leaving OPEC affect oil prices?
With the UAE's 5 million Barrels Per Day now outside OPEC+ quota discipline, Saudi Arabia faces pressure to decide whether to lift its own production to compensate or defend the cartel framework. Brent hit $123/barrel settle on 30 April — 87% above pre-war — as markets priced the supply uncertainty.Source: editorial
How many countries are in OPEC after the UAE left?
After the UAE's departure effective 1 May 2026, OPEC has 12 member states. The UAE was a founding Gulf pillar with the highest declared spare capacity of any cartel member.Source: editorial
Why did the UAE leave OPEC?
The UAE withdrew from OPEC and OPEC+ effective 1 May 2026 after years of quota disputes, citing unwillingness to subordinate its 5 million Barrels Per Day of capacity to cartel coordination. The structural backstory is the Saudi strike on a UAE convoy at Mukalla port in December 2025.Source: editorial
How much has OPEC cut its 2026 oil demand growth forecast?
OPEC's July 2026 Monthly Oil Market Report cut its 2026 global demand growth forecast for a fourth consecutive month, down to just +0.8 million barrels a day, extending a run of successive downgrades through the summer.Source: OPEC Monthly Oil Market Report, July 2026
What is the difference between OPEC and OPEC+?
OPEC is the core 12-nation cartel controlling around 30% of global crude output. OPEC+ is the broader compact including Russia and nine other non-OPEC producers, covering roughly 40% of global supply. Coordination in both depends on voluntary quota compliance.Source: editorial
When was OPEC founded and where is it based?
OPEC was founded in Baghdad in September 1960 by Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela. Its headquarters moved to Vienna, Austria in 1965, where it remains.Source: editorial
Did OPEC meet on production quotas in August 2026?
Yes. Russian Deputy Prime Minister Alexander Novak, representing OPEC+, chaired OPEC's 67th Joint Ministerial Monitoring Committee on 2 August 2026, the body that reviews members' output compliance.Source: Government of the Russian Federation
