OPEC+ Holds Oil Output Steady as Iran War Keeps Hormuz Flows Near a Standstill

OPEC and its allied producers agreed on Sunday to leave December oil-output targets exactly where they were in September, October and November, as a nine-month-old war between the United States and Iran continues to choke off a chokepoint that normally carries roughly a fifth of the world's traded crude. The decision, confirmed after a virtual meeting of the group's seven core members, extends a holding pattern that began in September and pushes any further policy shift into 2027.

Saudi Arabia, Russia, Iraq, Kuwait, Kazakhstan, Algeria and Oman make up the group that met Sunday; it is a subset of the broader OPEC+ coalition that also includes the United Arab Emirates and other producers bound by separate cuts. In a statement, the group said it would "maintain September 2026 required production for December 2026" and reaffirmed its "collective commitment to achieve full conformity" with the output-sharing framework known as the Declaration of Cooperation, the mechanism OPEC and non-OPEC allies have used since 2016 to coordinate supply.

The numbers

The seven members' combined required output stays at roughly 31 million barrels a day, unchanged since September. Individually, the targets are little changed from recent months: Saudi Arabia at 10.478 million barrels a day, Russia at 9.949 million, Iraq at 4.431 million, Kuwait at 2.676 million, Kazakhstan at 1.628 million, Algeria at 1.007 million and Oman at 841,000. The group finished unwinding 1.65 million barrels a day of voluntary 2023-era cuts in September but is holding a separate layer of roughly 2 million barrels a day in cuts through the end of this year.

What those targets don't capture is how much oil is actually reaching buyers. Most members are pumping well below their quotas because of the war's effect on Gulf shipping lanes. Data published by the U.S. Energy Information Administration's energy-security tracking page shows total oil flows through the Strait of Hormuz — crude, condensate and refined products combined — averaging 21.6 million barrels a day in the fourth quarter of 2025, before the fighting started. By the second quarter of 2026 that figure had collapsed to 4.9 million barrels a day, with crude and condensate alone falling from roughly 16 million to 3.7 million barrels a day over the same stretch. Liquefied natural gas flows through the strait fell just as sharply, from 10.5 billion cubic feet a day to 0.8 billion. The EIA itself cautions that ship-tracking data for the strait has been unreliable since the fighting began in late February and that its estimates are revised frequently, but the direction of the collapse is not in dispute.

Oil prices have moved accordingly. Brent crude settled Friday up 2.4% at $117.64 a barrel, touching $118 intraday and marking its highest close since late April and a fourth consecutive monthly gain, according to CNBC's report on trading ahead of the meeting. U.S. benchmark West Texas Intermediate finished the session up 2.1% at $104.12. Both benchmarks remain far above where they traded before the war: Brent was near $73 a barrel in late February, before fighting between the U.S. and Iran began.

Context: a war with no clear end

The conflict is now in its ninth month with no settlement in sight. Fighting began February 28, and the Strait of Hormuz — the narrow passage between Iran and Oman through which tankers must sail to reach the open Gulf of Oman — has been effectively unusable for normal commercial traffic since. Saudi Arabia and the United Arab Emirates have partly compensated by routing crude overland through pipelines to Red Sea terminals, but the EIA's own chokepoint analysis puts total bypass pipeline capacity at only about 4.7 million barrels a day — a fraction of the roughly 21 million barrels a day that used to move through Hormuz each quarter.

Houthi forces in Yemen have added a second front, escalating missile and drone attacks on Saudi Arabia through October; Saudi state media reported intercepting a hostile drone over Riyadh as recently as Saturday, part of a pattern of dozens of intercepted strikes on the kingdom's territory in recent weeks. October also produced the highest monthly count of attacks on commercial vessels in and around the strait this year, with at least 35 incidents reported, according to reporting from The National. Israeli media have reported preparations for a possible renewed Israeli campaign against Iran, and traders are watching for signs that Washington could resume direct military action once the U.S. midterm elections have passed, even as the White House has said the war "will be wrapped up soon."

Who is affected

The practical effect of OPEC+ standing pat is to leave the supply side of the oil market almost entirely dependent on how the war develops rather than on producer-group policy. That has several groups watching closely:

• Fuel-importing economies and households, who face a fourth straight month of rising crude costs feeding into gasoline, diesel and jet-fuel prices, with knock-on effects for shipping and airline costs.
• Gulf treasuries, which depend on oil revenue for government budgets; lost export volumes through Hormuz are only partly offset by higher per-barrel prices, and the EIA's Short-Term Energy Outlook has repeatedly revised its price forecasts this year as the disruption has proven more persistent than first assumed.
• U.S. shale producers, for whom sustained prices above $100 a barrel for WTI improve drilling economics after a stretch of lower prices earlier in the decade.
• Central banks, including the Federal Reserve, which are tracking energy costs as a factor in inflation readings even as other price pressures have eased.

Reaction and what's next

The decision to hold output steady matched what traders and analysts had expected heading into the weekend; Reuters reporting ahead of the meeting had already flagged that no change was likely and that sources inside the group described the focus shifting toward 2027 rather than any near-term adjustment. That expectation was echoed across multiple outlets covering the group's deliberations, and the muted market reaction — oil's advance on Friday reflected war risk more than any surprise from the producer group — suggests the decision itself was already priced in.

OPEC+ said it would keep holding monthly meetings to review conditions, with the next session scheduled for November 29, alongside a broader ministerial meeting of OPEC and non-OPEC members the same week. Before any new output path can be set, the group needs to complete a review of individual members' spare production capacity, a technical exercise that will determine the baselines used to calculate each country's quota starting in 2027. That process, already delayed by the disruption to normal trading and shipping patterns, is now the central item on OPEC+'s agenda for the rest of the year. Barring a ceasefire or a significant de-escalation in the Gulf, traders expect the group's December 2026 output levels — and the elevated prices that have accompanied them — to persist largely unchanged into the new year.
