OPEC+

What it is

OPEC+ is a coalition of 22 oil-producing nations coordinating crude production to manage world prices. It has two layers. The original OPEC, founded in Baghdad in September 1960 by Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela, counts 12 members after Angola left in January 2024. The "+" adds 10 non-OPEC producers, most importantly Russia, who joined via a Declaration of Cooperation in December 2016. Together the bloc controls roughly 48 million barrels per day (bpd), about 59% of global crude output. The Secretariat sits in Vienna, Austria.

The mechanism is quota-based: each member receives a production ceiling and monthly ministerial meetings can raise or lower aggregate targets. Overproducers file "compensation" schedules, though quotas are not legally binding. Iraq and Kazakhstan have been the chronic compliance laggards. Saudi Arabia functions as swing producer, absorbing most adjustment burden when the group needs rapid price defense.

History

OPEC's founding purpose was to shift control of oil pricing from the "Seven Sisters" Western majors to producing nations. The 1973 Arab oil embargo proved the cartel's ability to move prices dramatically. Through the 1980s, Saudi Arabia failed to enforce discipline, and a long price collapse followed.

The 2014-16 US shale boom pushed Brent below US$30 in early 2016. Saudi Arabia brokered the December 2016 Declaration of Cooperation with Russia and nine other non-members, creating OPEC+. A second stress test came in 2020, when COVID demand collapse triggered a brief Saudi-Russia price war before a record 9.7 million bpd cut in April 2020.

From 2022 through early 2026, OPEC+ maintained a cumulative reduction of 3.66 million bpd relative to a 2018 baseline to defend prices above US$80. Eight voluntary-cut members, led by Saudi Arabia, Russia, Iraq, UAE, Kuwait, Kazakhstan, Algeria, and Oman, added a further 1.65 million bpd reduction in April 2023.

Current state

As of July 2026, OPEC+ is in a deliberate unwind. Starting in April 2026, the eight voluntary-cut members began adding back output in monthly increments, initially 138,000 bpd, then a steady 188,000 bpd per month through at least August. By early July the cumulative additions total over 600,000 bpd. The strategy reflects two shifts: first, Iran's re-entry into global markets after the US-Iran June 2026 ceasefire ended the naval blockade of the Strait of Hormuz, adding millions of barrels that the group cannot offset; second, a Saudi and UAE decision to recover market share from US shale producers, who face marginal cost around US$65-68 per barrel. Brent flipped into contango on June 25 as the war premium drained. By July 2, Brent touched US$67.74, its lowest since February, as the group's fourth consecutive hike landed. Brent fell roughly 30% in Q2 2026, its worst quarter since COVID.

A July 5, 2026 ministerial meeting of the seven-country compliance group reviewed overproduction by Iraq and Kazakhstan. Both face compensation schedules through December 2026.

Relationships

Saudi Arabia and Russia are the two anchors. Saudi Arabia holds the world's largest proven reserves and lowest production cost, giving it unmatched swing capacity. Russia depends on oil revenues for budget financing and has historically overproduced against its quota. Crown Prince Mohammed bin Salman and President Vladimir Putin built a personal alignment in 2016 that has held, with friction, since.

Iraq's 4+ million bpd output makes it the group's second-largest producer, but domestic political pressure produces chronic compliance failures. Kazakhstan's Tengiz and Kashagan fields run expansion-oriented, generating recurring overruns. The UAE, after winning a higher baseline in 2021, is positioned as a low-cost expander aligned with Saudi strategy.

Iran holds observer-exempt status; sanctions and the ceasefire govern its output outside quota arithmetic. Iran's seaborne export recovery in June-July 2026 has been the single largest supply addition of the year. Saudi Aramco's Ras Tanura terminal suffered a drone strike on June 28, briefly interrupting the Gulf's largest export hub before operations resumed.

What to watch

Whether the August 2026 increment holds depends on the July 5 compliance review and Brent's price floor. At US$65-67, several members face fiscal stress. Fertilizer prices dependent on Gulf gas are a lagging supply-repricing indicator. The longer-term question is whether Saudi Arabia can sustain a market-share strategy that compresses government revenue, or whether the group reverts to price defense.
