War in the Middle East recalibrates global energy markets

9 April 2026

 

The US and Israel’s war with Iran, and the disruption it is causing to oil and gas shipping, are having a deep impact on global energy markets and will have lasting effects on how decisions are made about energy production and consumption.

In March, the director of the Paris-based International Energy Agency, Fatih Birol, said the world was “facing the greatest global energy security threat in history”, eclipsing even the 1973 oil crisis triggered by Opec’s oil embargo against countries that supported Israel during the Yom Kippur War.

Iran’s effective closure of the Strait of Hormuz has highlighted the fragility of the Middle East oil and gas supply chain, and will incentivise import-dependent economies to pursue greater energy security.

There are already signs around the world that this is taking place in a range of ways, including developing domestic fossil fuel reserves, accelerating nuclear projects, and investing in renewables and battery storage.

At the same time, high oil and gas prices are spurring fossil fuel producers to increase investment in boosting output and protecting export routes, as they seek to maximise profits amid reduced global supplies.

The oil price shocks of the 1970s shaped key oil and gas partnerships between Saudi Arabia and the US, and helped drive the development of strategic petroleum reserves, energy-efficiency policies and broader efforts to diversify energy supply.

In a similar way, the current crisis is dramatically reshaping the global energy landscape, potentially eroding some of the key agreements that emerged in the 1970s and accelerating a new wave of diversification.

Unparalleled crisis

The scale of the current energy crisis is unprecedented, with global markets losing 11 million barrels a day (b/d) of oil supply due to the effective closure of the Strait of Hormuz.

On top of this, 20% of the world’s LNG production cannot be shipped.

This combined drop in available oil and gas is far larger than during the price shocks of the 1970s.

In the 1973 crisis, the world lost around 5 million b/d of oil; the same was true of the second shock in 1979, following the Iranian Revolution.

Deepening the current crisis, significant damage is being inflicted on oil and gas infrastructure across the Middle East, which is likely to take years to repair.

Refineries have been attacked across the region, including in Iran, Kuwait, Bahrain and Saudi Arabia. There have also been multiple strikes on storage facilities, oil fields, gas processing facilities and shipping terminals.

While the price shocks of the 1970s led to a global recession and had sweeping, long-term consequences for businesses and consumers worldwide, the latest crisis has the potential to be even more severe and is already causing major disruption in energy markets.

Advisory firm Oxford Economics has forecast that, if the war is prolonged and the Strait of Hormuz remains closed for between three and six months, the result would be a global recession and world GDP growth would slow to 1.4% in 2026.

Demand destruction

Experts say the war is already driving oil and gas “demand destruction”, as governments, companies and households respond to price spikes and supply-chain fragility by reducing reliance on hydrocarbon imports.

Decisions being made now to reorient away from oil and gas could have a lasting impact on future import demand worldwide.

Even though it is less than two months since the war started, choices are already being made that could reduce demand for oil and gas in the years ahead.

In Vietnam, conglomerate Vingroup has asked the government to allow it to replace a planned $6bn liquefied natural gas (LNG) power project – which would have been the country’s largest – with a renewable energy project, citing surging fuel prices linked to the Middle East conflict.

Similarly, in New Zealand, plans to develop a new LNG import terminal on the country’s North Island are becoming increasingly uncertain. On 30 March, Prime Minister Christopher Luxon said the government would only approve the project if the business case stacked up, and it has been reported that officials are considering replacing it with a large hydroelectric project.

Christopher Doleman, a gas specialist at the Institute for Energy Economics and Financial Analysis (Ieefa), said: “There were existing concerns about the high price of LNG and potential volatility and these concerns have increased significantly since the war began – leading several developers to consider other options, which in some cases include renewables projects.”

At a consumer level, demand destruction is also taking place, as high prices for oil- and gas-linked products drive increased sales of solar panels and electric vehicles.

In March, Octopus Energy, the UK’s largest supplier of domestic electricity and gas, said it had seen a sharp rise in solar panel sales during the price shock, with purchases up 54%.

Also in the UK, March set a monthly record for electric car sales, with 137,000 vehicles sold — a 14% increase on the same period in 2025. Rising electric vehicle sales were also reported in the US and the EU.

French used-car dealer Aramisauto said the share of its total sales accounted for by electric vehicles rose from 6.5% to 12.7% within three weeks of the start of the war. In Germany, the share of electric car search queries on the platform mobile.de rose from 12% to 36%, with dealers reporting 66% more enquiries for used electric cars than in February.

Some Asian countries are also seeing a shift away from gas for cooking. In India, amid an ongoing liquefied petroleum gas shortage, electric stoves have seen a surge in demand, with some retailers reporting they sold three times their usual monthly volume in just a few days.

The global shift away from fossil fuels — both in major power and import projects and at the consumer level — is likely to have significant long-term implications for energy demand.

That would fundamentally alter demand forecasts for Middle East producers and could weigh on revenues in the years ahead.

What we are seeing in the global energy sector is that there are very clear beneficiaries of the ongoing conflict … exporters that aren’t reliant on the Strait of Hormuz can take advantage of high oil prices to post profits and sanction new projects
Slava Kiryushin, HFW

Bolstered prospects

While many Middle East oil and gas producers are seeing their exports severely restricted due to attacks on infrastructure and the disruption of shipments via the Strait of Hormuz, the war is bolstering the prospects of producers in other regions.

High prices are delivering windfall profits, while investment is flowing towards projects perceived as less exposed to future attacks or a renewed blockade of the strait.

Over time, these forces could contribute to a global divergence: Middle East producers could miss market-share targets, while suppliers elsewhere outperform.

Commenting on the implications of the conflict, Slava Kiryushin, an international oil and gas lawyer and partner at London-headquartered law firm HFW, said: “There has already been a massive impact from this conflict on global energy markets. Producers in the GCC have been impacted more than others.

“The most important factors right now are the damage caused to infrastructure from strikes on energy facilities and how quickly those can be remedied,” he said. “Even if this war ends tomorrow, many will remain concerned about political tensions in the region and the potential for future disruptions.

“What we are seeing in the global energy sector is that there are very clear beneficiaries of the ongoing conflict … exporters that aren’t reliant on the Strait of Hormuz can take advantage of high oil prices to post profits and sanction new projects.”

As revenues fall, repair costs rise and projects stall for national oil and gas companies in Saudi Arabia, Qatar, Iraq, Kuwait and Bahrain, companies active in regions including the US, Australia, Russia and Africa are seeing significant benefits.

Despite Ukrainian strikes on key Russian oil infrastructure, Moscow has reported surging oil revenues as the war in Iran drives up global crude prices and boosts demand for Russian crude.

In March, Ukraine’s Kyiv School of Economics (KSE) estimated Russia was earning about $760m a day from oil exports, benefitting from high prices and US sanctions waivers.

Even if the conflict ends in the coming weeks, Russia’s annual oil and gas export revenues are projected to reach $218.5bn this year, up 63% from a scenario in which Middle East energy supplies remain uninterrupted, KSE said. That would amount to an additional $84bn in windfall revenue.

US oil companies are also seeing bumper profits and higher share prices. Even as the broader US stock market has moved lower, ExxonMobil and Chevron shares have risen by more than 20% since the start of the year.

Market research firm Rystad Energy has estimated that US oil producers could earn an additional $63bn in profit this year due to elevated prices.

As producers outside the Middle East record large profits and ramp up output, some analysts argue the region’s future standing in global energy markets could be undermined.

Commenting on the outlook for Qatari LNG, Doleman said: “Over the long term, the ongoing conflict could weaken Qatar’s bargaining position when the country is negotiating long-term gas contracts due to perceived risk associated with using the Strait of Hormuz.

“Exports from other suppliers such as producers in the US or Australia could be viewed as more reliable and this could lead to the removal of resale restrictions and other elements that customers in Asia have been pushing back against for some time now.”

Structural changes

While uncertainty remains over how the war will end and how extensive future disruptions to energy supplies may be, it is increasingly likely the crisis will bring structural changes to global energy flows.

There have already been shifts in energy relationships, with clients of GCC oil and gas producers seeking alternative suppliers and sanctions on Iranian and Russian oil being temporarily eased.

While many of the arrangements made in the short period since the war began are likely to be temporary, some could become more durable over time.

Iran has made the removal of sanctions one of its key demands to end the conflict with the US and Israel.

With oil prices remaining high, many countries hit by rising energy costs would welcome the extension of sanctions waivers beyond existing deadlines, to keep crude supplies to global markets as high as possible.

The scale and permanence of these changes will depend on how quickly the conflict can be resolved, and what assurances can be put in place to prevent it flaring up again.

If the conflict is resolved quickly, it is possible that oil and gas sectors in Iraq and the GCC could see a significant rebound, returning towards pre-war operations.

Prior to the war, low production costs in countries such as Saudi Arabia, Kuwait and Iraq made them among the most profitable exporters in the world, and analysts believe that cost advantage will support a recovery once the Strait of Hormuz reopens.

“Though a lot of damage is being done, Middle East producers still have the advantage of some of the world’s cheapest and easiest-to-produce oil and gas,” Doleman said. “This means they are likely to retain their clients and a functioning business model once the Strait of Hormuz reopens.”

However, if the conflict continues for an extended period, the prospect of a swift recovery would diminish and more dramatic structural changes to the global oil and gas industry would become more likely.

That, in turn, could make the Middle East’s future role in global energy markets significantly smaller than previously forecast.

  • Brent hits $112 a barrel following Saudi oil field attack

    22 October 2026

    Register for MEED’s 14-day trial access 

    Oil prices climbed more than 3% on 22 October after a drone targeting Saudi Aramco’s Shaybah oil field development killed two people and injured two others a day earlier, adding to concerns over energy supplies as attacks on Saudi energy infrastructure intensified.

    Global benchmark Brent crude hit $112.30 in early trading on 22 October, but later pared gains and was trading at $111.52 a barrel as of 11am GST.

    Three residents and a Saudi citizen were killed in two separate incidents in Saudi Arabia’s Eastern Province on 21 October, authorities said, as attacks on the kingdom accelerated following an escalation of hostilities with the Iran-backed Houthi group in neighbouring Yemen.

    Overnight, the Saudi-led coalition fighting the Houthis in Yemen announced that it had intercepted and destroyed four drones in the Eastern Province.

    Saudi air defences intercepted a drone attempting to target a processing facility at Saudi Aramco’s Shaybah oil field development on the morning of 21 October, the Saudi Ministry of Energy said.

    The official Saudi Press Agency (SPA) carried a statement quoting an energy ministry official as saying the attempted attack resulted in the deaths of two residents – a Filipino and a Nepali – and injuries to two others – an Indian and a Pakistani – after debris fell due to the interception.

    Following the interception, a fire broke out in a vehicle belonging to a contractor at the Shaybah oil field, outside the facility’s perimeter, with no impact on operations.

    Dammam airport attack

    Separately, a Houthi attack on King Fahd International airport in Dammam on the evening of 21 October killed an Indian resident and a Saudi citizen.

    Eight people were also injured in the attack, including a Saudi national, a Nepali, and two nationals each from India, Yemen and Bangladesh. Injuries ranged from minor to critical, the Saudi General Authority of Civil Aviation (Gaca) said the next day.

    “The attack also caused property damage, the extent of which is currently being assessed. Further updates will be provided,” Gaca said, adding that operations had since resumed at Dammam airport.

    Saudi Arabia has come under sustained attack from the Iran-aligned Houthi rebel group in October, including strikes on Riyadh’s international airport in what authorities described as the kingdom’s deadliest incidents in years, as the war with the group escalates.

    The Houthi militias also struck an administrative building at Aramco’s headquarters in Dhahran, in the Eastern Province, on 13 October, resulting in a limited fire.

    The Houthi rebels opened a new front in the regional war between Iran and the US in mid-July, when they breached a four-year truce with Saudi Arabia in Yemen’s civil war, which began in 2014, and started attacking Saudi vessels and Aramco energy assets along the Red Sea, including repeated strikes on the Jizan refinery.

    The 1,200-kilometre East-West pipeline operated by Aramco was also hit by Houthi missiles in September, and once directly by Iran in April.

    The East-West pipeline transports crude from Saudi Arabia’s Eastern Province oil fields to the Red Sea port city of Yanbu on the kingdom’s west coast. It has a pumping capacity of 7 million barrels a day.

    Saudi Arabia relies heavily on the East-West pipeline to bypass the volatile Strait of Hormuz maritime chokepoint and ship crude from its Red Sea coast. Riyadh has increasingly used the line to route exports away from Hormuz since the US-Iran conflict began on 28 February – a tactical advantage most of its Gulf neighbours lack.

    Aramco resumed crude exports via the pipeline at the start of October.

  • Nebius agrees Neom AI data centre capacity deal

    22 October 2026

    Register for MEED’s 14-day trial access 

    Saudi artificial intelligence (AI) company Humain and data centre developer DataVolt have signed a preliminary framework agreement with Netherlands-based AI cloud company Nebius for up to 50MW of data centre capacity at Oxagon, Neom’s industrial city on the kingdom's Red Sea coast.

    Under the proposed agreement, Nebius will become an anchor customer at the planned AI data centre campus.

    The contemplated capacity represents half of the initial 100MW currently under construction, which forms part of a planned 360MW first phase.

    The capacity is expected to be commissioned in stages from the fourth quarter of 2027.

    Humain, which is owned by Saudi sovereign wealth vehicle the Public Investment Fund, and DataVolt began construction on the initial 100MW facility at Oxagon in September. The wider campus is planned to reach 1.5GW of capacity.

    The agreement was signed during Nvidia’s GTC event in Berlin, held on 20-22 October. The US graphics processing unit (GPU) designer hosts the GPU Technology Conference (GTC) to showcase advances in AI and accelerated computing.

    Nebius is expected to deploy Nvidia-powered computing infrastructure at the Oxagon campus to support its AI cloud business and international customer base.

    The project combines Humain’s AI capabilities with DataVolt’s experience in developing, financing and operating digital infrastructure. It is intended to support large-scale AI and cloud workloads for Saudi and international customers.

    Oxagon is seeking to position itself as a location for energy-intensive digital infrastructure, supported by pre-zoned industrial land, power resources and subsea cable connectivity to Europe and Africa. The development is also expected to incorporate renewable energy and advanced cooling systems.

    The Oxagon campus builds on an agreement signed in February 2025 by Neom and DataVolt to develop data centre infrastructure at the site. That deal involved an investment of about $5bn and envisaged a 1.5GW development.

    In September 2025, DataVolt signed a memorandum of understanding with South Korea’s LG Electronics covering cooling systems for the Oxagon data centre project.

    DataVolt was founded in 2023 and is a wholly owned subsidiary of Saudi infrastructure developer Vision Invest. Humain was launched in May 2025 to develop capabilities across the AI value chain, including data centres, high-performance computing infrastructure, cloud platforms and AI models.

    Register for MEED’s 14-day trial access 

    The Royal Commission for Riyadh City (RCRC) has awarded an estimated SR1.13bn ($301m) contract to local firm Alomaier Trading & Contracting Company to upgrade a section of Sheikh Jaber Al-Ahmad Al-Sabah Road in the capital.

    The project covers the construction of an urban road about 3 kilometres (km) long, with a right-of-way width of about 120 metres.

    The scope of work includes the delivery of three interchanges featuring post-tensioned, voided-slab concrete bridges; a cut-and-cover tunnel; and three box culverts designated IC02, IC03 and IC04.

    The contract also encompasses pumping and lifting stations, stormwater drainage and irrigation networks, earthworks, asphalt paving, roadway lighting, power distribution systems, mechanically stabilised earth retaining walls and landscaping works.

    The award forms part of RCRC’s wider programme to upgrade Riyadh’s arterial road network, decongest critical bottlenecks and expand transportation capacity in the city ahead of Expo 2030 and the 2034 Fifa World Cup.

    The contract award follows RCRC’s appointment in May of a joint venture of Riyadh-based Al-Rashid Trading & Contracting Company and Turkiye’s IC Ictas for an estimated SR5bn ($1.3bn) contract to construct another section of Sheikh Jaber Al-Sabah Road.

    That project covers 12km from Khurais Road to Al-Thumama Road and is a component of Riyadh’s Second Eastern Ring Road scheme.

    Alomaier Trading & Contracting Company has secured several contracts in recent months.

    In August, Saudi Arabian Railways awarded the contractor an estimated SR4bn-plus ($1.1bn) contract to add a second track to the first section of the existing phosphate railway in the kingdom’s Eastern Province.

    The railway package covers about 100km between AZ1/Nariyah Yard and Ras Al-Khair. Works include track doubling, alignment modifications, utility bridges, culvert widening, hydrological structures, conversion of the AZ1 siding into a mainline track, and enabling works for signalling and telecommunications systems.

  • Dewa International signs energy and infrastructure MoUs

    22 October 2026

    Dubai Electricity & Water Authority’s (Dewa) new development arm, Dewa International, has signed four memorandums of understanding (MoUs) with international partners to explore investment and project development opportunities in the energy, water and infrastructure sectors.

    The agreements, signed during Dubai’s Water, Energy, Technology and Environment Exhibition (Wetex 2026), follow the launch of the wholly owned subsidiary in June, as reported by MEED.

    At the time, the utility said the arm would be used to export Dubai’s energy and water infrastructure model, with a focus on developing conventional and clean energy projects for global markets.

    At Wetex, Dewa International signed an MoU with France’s EDF Power Solutions to explore potential joint participation in solar, wind, battery energy storage and pumped-storage hydropower projects.

    A separate agreement with China Energy International Group explores the company’s potential role as an engineering, procurement and construction (EPC) partner for major energy, water and infrastructure projects. The MoU also covers cooperation in project development and EPC services.

    A further agreement with UK-based Capital Dynamics focuses on potential joint investments in operational clean energy assets in Europe. The parties will also explore establishing an investment vehicle for future clean energy infrastructure investments.

    Dewa International also signed a fourth agreement with Mumbai-Headquartered Tata Consultancy Services, exploring the company’s potential role as a technical consultancy partner. The scope covers technology strategy, information technology and operational technology integration, and asset performance management solutions.

    Dewa currently has almost $7bn-worth of power and water projects under execution across the UAE, according to regional projects tracker MEED Projects.

    Its flagship Mohammed Bin Rashid Al-Maktoum Solar Park is the largest single-site solar park in the world. The utility is currently advancing the project’s seventh phase, with Abu Dhabi Future Energy Company (Masdar) recently submitting the lowest bid for the project, as exclusively reported by MEED.

  • EGA’s Al-Taweelah restoration reaches 50% completion

    22 October 2026

    Register for MEED’s 14-day trial access 

    The UAE’s Emirates Global Aluminium (EGA) has announced that half of the reduction cells at its Al-Taweelah smelter in Abu Dhabi, which sustained damage from Iranian attacks in late March, have been restarted.

    On 28 March, drone and missile attacks by Iran on Khalifa Economic Zone Abu Dhabi (Kezad), where the smelter is located, led to an emergency shutdown of the facility and injured two EGA employees, who were later discharged from hospital.

    To restore hot metal production, EGA said it must progressively repair and restart each reduction cell. So far, 631 of the 1,262 reduction cells at Al-Taweelah have been restarted.

    EGA – which is jointly owned by the governments of Abu Dhabi and Dubai – is working on all three potlines at Al-Taweelah in parallel, to accelerate the rate of reduction cell start-ups. Potline 1 was energised on 26 May, followed by Potline 3 on 13 July and Potline 2 on 3 August.

    After being restarted, a reduction cell typically takes a week to stabilise and reach full production. Some hot metal is used to restart subsequent reduction cells, with the balance being delivered to EGA’s Al-Taweelah casthouse, to be cast into finished premium aluminium products.

    Following the emergency shutdown, molten aluminium froze in every reduction cell at Al-Taweelah, leaving solid metal pads weighing up to 45 tonnes, which needed to be removed. Almost 80% of the reduction cells can then be restarted. The remaining reduction cells require repairs, potlining demolition and relining, depending on how long the reduction cells had been operating before the incident.

    Periodically cutting out, repairing and relining reduction cells at the end of their operating life is routine in aluminium smelting. Compared to the normal rolling maintenance programme, EGA has more than tripled its capacity in order to safely repair and restart reduction cells at Al-Taweelah, by optimising workflows, adding equipment, strengthening employee capability and deploying industrial process innovations.

    About 1,000 employees are working on the restoration of hot metal production at the Al-Taweelah smelter, EGA said in a statement on 26 August.

    During the restoration, EGA has accelerated the deployment of a technology pilot at Al-Taweelah that would otherwise have required operating reduction cells to be shut down. The pilot E40 upgrades to 13 DX technology reduction cells will be used to prove the performance of the technology before industrialisation across all 808 DX technology cells at Al-Taweelah.  

    If applied to all DX reduction cells, EGA’s E40 technology has the potential to increase hot metal production by 67,000 tonnes a year (t/y).

    EGA’s Al-Taweelah alumina refinery is located next to the Al-Taweelah smelter.

    Alumina is the feedstock for aluminium smelters. It is transferred to storage and then into the smelter by a system of conveyor belts.

    The Al-Taweelah alumina refinery continues to produce alumina at approximately 50% capacity, EGA said. While the alumina refinery is technically ready to ramp-up further, timing will be based on supply chain dynamics and the optimisation of EGA’s alumina sourcing strategy.

    The company announced on 10 July that it had restarted alumina production at its main refinery in Al-Taweelah, adding at the time that it expected to have the technical capability to ramp up to full alumina production by the end of this year.

    The Al-Taweelah alumina refinery began production in 2019 and has a nameplate capacity of 2 million t/y. 

    EGA’s Al-Taweelah smelter consists of 1,262 reduction cells and produced 1.6 million tonnes of cast metal in 2025.

    The Al-Taweelah alumina refinery produced 2.4 million t/y of alumina in 2025, and met 46% of EGA’s alumina needs.

    EGA also said in July that its site in the Jebel Ali area of Dubai is continuing aluminium production at full capacity. Average daily inbound deliveries of all major raw materials exceed EGA’s requirements to maintain metal production at Jebel Ali and meet the demands of restoration at Al-Taweelah, with raw material stocks in the UAE increasing.

    Separately, the ramp-up of production at EGA’s new Al-Taweelah recycling plant remains on track, with full production expected by late in the fourth quarter of this year.

    EGA’s recycling plants in the US and Germany, meanwhile, have continued production throughout 2026.
