Middle East Conflict to Cut Global Crude Runs by 1.4 Million bpd in Q4, Wood Mackenzie Says
Wood Mackenzie has warned that the prolonged conflict in the Middle East will reduce global crude oil processing by an estimated 1.4 million barrels per day (bpd) in the fourth quarter of 2026. The forecast highlights how geopolitical tensions are disrupting refining operations worldwide, tightening product markets, and elevating refining margins even as crude supply dynamics continue to evolve.
This projected cut in crude runs — the volume of oil processed by refineries into fuels and other products — underscores the broader impact of the crisis beyond just crude prices.
What Wood Mackenzie’s Analysis Reveals
According to the energy research firm, the Middle East conflict is reshaping oil markets by constraining refinery feedstock availability and operational capacity. Senior Vice President Alan Gelder of Wood Mackenzie’s refining, chemicals, and oil markets research noted that the scale of disruption to global crude runs is without modern precedent.
The reduction stems from a combination of factors, including limited access to certain crude grades, logistical challenges, and the need for refiners to adjust operations amid uncertainty. These effects are expected to be most pronounced in the final quarter of the year.
Compounding Factors: Russian Refinery Disruptions
The Middle East situation is being amplified by ongoing Ukrainian drone attacks on Russian refining assets. These attacks left approximately 3.5 million bpd of Russian refining capacity offline in August 2026. The dual shocks from the Middle East and Russia have created one of the tightest refining environments in recent history.
As a result, planned maintenance programs in Europe and the United States have been delayed, further supporting higher refining margins as product supply remains constrained relative to demand.
Why Crude Runs Matter More Than Crude Prices Alone
While oil price volatility often dominates headlines, reduced refining capacity poses a more immediate risk to fuel availability. Crude oil must be processed into gasoline, diesel, jet fuel, and petrochemical feedstocks before it can be used. A sustained 1.4 million bpd drop in global crude runs means fewer refined products enter the market, even if adequate crude supplies exist elsewhere.
This dynamic can lead to regional product shortages, higher retail fuel prices, and increased competition for available refined barrels.
Historical Context of Refining Disruptions
Major geopolitical events and infrastructure attacks have previously constrained refining. Past conflicts in the Middle East and sanctions-related issues have forced temporary run cuts. However, the simultaneous pressure from Middle East supply chain disruptions and Russian capacity losses marks a rare combination that is testing the resilience of the global refining system.
Refiners in Asia, Europe, and other regions that rely on Middle Eastern crude grades have been particularly exposed to feedstock and logistics challenges since the conflict intensified earlier in 2026.
Impacts on Global Oil Markets and Refining Margins
The projected run cuts are expected to keep product markets tight into the end of 2026. Higher refining margins benefit complex refineries that can process a wider range of crudes or maximize high-value product yields. Conversely, simpler facilities or those heavily dependent on disrupted supply routes face greater operational challenges.
Consumers may experience elevated prices for transportation fuels, while airlines and industrial users could face higher costs for jet fuel and other middle distillates. Petrochemical producers may also see tighter feedstock availability.
Regional Implications
Asia, with its high reliance on Middle Eastern crude, has already faced significant run adjustments earlier in the year. Europe and the United States are now dealing with delayed maintenance and the need to secure alternative feedstocks. The overall effect is a more fragmented and regionally differentiated refining landscape.
Future Outlook and Potential Scenarios
Wood Mackenzie’s forecast assumes the current level of disruption persists into the fourth quarter. If the conflict de-escalates and logistics normalize, some of the projected run cuts could be reversed. Conversely, further escalation or additional infrastructure damage would likely deepen the reductions.
Refiners are expected to continue optimizing crude slates, maximizing utilization of available capacity, and adjusting product yields to capture margin opportunities. Inventory management and strategic stock releases may also play a role in balancing product markets.

Frequently Asked Questions
What does a cut in crude runs mean?
It refers to a reduction in the volume of crude oil that refineries process into finished products such as gasoline, diesel, and jet fuel.
Why is Wood Mackenzie forecasting a 1.4 million bpd reduction in Q4?
The prolonged Middle East conflict is disrupting feedstock availability, logistics, and refinery operations on a scale not seen in recent decades.
How do Russian refinery attacks factor in?
Ukrainian drone strikes have taken about 3.5 million bpd of Russian refining capacity offline, compounding the Middle East-related pressures.
Will this lead to fuel shortages?
It increases the risk of tighter product markets and higher prices, though actual shortages depend on regional inventory levels and alternative supply sources.
What can refiners do in response?
They may delay maintenance, optimize crude selection, adjust product yields, and seek alternative feedstock sources to maintain operations.
How long could these effects last?
The Q4 forecast reflects current conditions. Resolution of the conflict or improved logistics could ease pressures, while further disruptions would extend them.
Navigating a Challenging Refining Landscape
Wood Mackenzie’s projection of a 1.4 million bpd reduction in global crude runs during the fourth quarter of 2026 highlights the far-reaching consequences of the Middle East conflict on the refining sector. Combined with ongoing Russian capacity losses, the situation has created an unusually tight environment for refined products.
As the year progresses, market participants will closely monitor geopolitical developments, refinery utilization rates, and product inventory levels. The ability of the global refining system to adapt will determine how severely these constraints translate into higher costs for consumers and industries worldwide.
