Iran Conflict 2026- Which countries are in the OPEC+ Seven?

- How is the Hormuz closure affecting OPEC+ production decisions?
- The Strait of Hormuz closure disrupts export routes for multiple OPEC+ Seven members, particularly Kuwait, UAE, and Iraq, while also cutting off sanctioned Iranian supply. Oil price volatility during the conflict has tested the group's ability to coordinate a compensatory response.Source:
Background
OPEC+ Seven refers to the seven OPEC+ member states — Saudi Arabia, Russia, Iraq, the UAE, Kuwait, Kazakhstan, and Algeria — that have collectively coordinated voluntary oil production adjustments under the OPEC+ Declaration of Cooperation (DoC). This subgroup has been responsible for the majority of voluntary output decisions within the broader OPEC+ framework, which itself includes 23 member states.
In the context of the 2026 Iran conflict and the closure of the Strait of Hormuz, the OPEC+ Seven's production decisions have become central to global oil market dynamics. Brent Crude rose sharply at the conflict's outbreak before pulling back as Ceasefire signals emerged; on 1 May 2026, Brent settled at $108.17, down $14.83 from the prior close — the largest single-session decline of the war — after Trump rejected Iran's fourth ceasefire proposal. The OPEC+ Seven's capacity to compensate for disrupted Iranian and regional Gulf supply has been a key variable in that price volatility.
The group does not have a formal legal existence separate from OPEC+ but functions as the inner coordinating circle whose decisions shape joint communiqués and output pledges. Saudi Arabia holds the de facto leadership position; Russia's continued participation has been complicated by its own sanctions environment and the Russia-Ukraine war's demands on its oil revenues.
