Oil companies will have to look further afield for new fossil fuel resources now that the Iran war has dented the investment allure of the energy-rich Middle East. Higher oil prices will give them that chance.
Major international oil companies, including Exxon Mobil, Chevron, TotalEnergies, Shell and BP, have long been drawn to the Middle East by its vast resources, stable fiscal terms and, until recently, relative political stability. The region accounts for roughly a fifth of global oil and liquefied natural gas (LNG) production.
That reputation, built painstakingly over decades even as wars raged in Iraq and Yemen, has now been shattered by the U.S.-Israeli war with Iran.
Now in its fifth week, the conflict has put energy infrastructure squarely in the crosshairs. Dozens of facilities across the Gulf have been damaged, including Qatar’s giant LNG hub and several major oil refineries.
The closure of the Strait of Hormuz - through which roughly 20% of the world's oil and gas normally flows - has forced producers to shut oilfields, costing the region an estimated $1 billion a day in lost export revenues, according to Reuters calculations based on pre‑war prices.
The longer‑term costs will be far higher. Restarting operations and repairing damaged facilities will likely run into the tens of billions of dollars - if not far more. QatarEnergy said an Iranian missile strike on February 18 could cost it about $20 billion a year in lost revenue and take up to five years to repair.
But no amount of money may be able to repair the region’s reputational damage – at least not in the short term – and that is likely to rapidly reshape Western energy majors’ upstream strategies.
A Steeper Risk Premium
The Middle East will clearly remain a major source of oil and gas for decades. It holds about half of the world’s proven oil reserves and 40% of gas reserves. Western companies are thus unlikely to abandon it altogether.
It currently makes up a substantial portion of many majors’ portfolios, including 41% of Exxon’s reserves, 42% of TotalEnergies’ and a quarter of Shell’s, according to consultancy Welligence.
The region attracted around $130 billion in oil and gas investment in 2025, roughly 15% of the global total, according to the International Energy Agency.
But unless the Iran war ends with a new, non-belligerent government sitting in Tehran - an outcome that currently appears remote - the conflict will leave deep scars.
Uncertainty over the safety of transit through Hormuz and the higher risk of conflagration is apt to sharply boost the cost of deploying staff, equipment, insurance and capital in the Middle East, making the region a lot less attractive for exploration.
This rising risk premium in the world’s largest energy-producing region is already being reflected in long-term oil prices.
Since the eve of the conflict, the average Brent crude price expected in 2030 0#LCOhas jumped about 10% to roughly $72 a barrel. Once the full extent of the damage from the war is known, that could rise even further.
Geographical Rebalancing
A structurally higher oil price would change the upstream calculus for the world’s energy giants.
This shift comes as the industry’s appetite for new oil and gas investment has been strengthening. Over the past year, oil companies have significantly increased spending on exploration worldwide - from West Africa and the eastern Mediterranean to Brazil and Southeast Asia.
That was a sharp break from the prior decade, when shareholder pressure and fears of a rapid demand decline driven by the energy transition reduced upstream investment. Today, companies – spurred by new outlooks suggesting fossil fuel demand won’t peak until next decade – are increasingly confident that more supply will be needed through the end of the decade.
Of course, exploration remains a high‑risk, high‑reward business requiring heavy upfront investment. Projects can also often take more than a decade to progress from the first drilling campaign to production.
Still, higher long-term prices would expand the pool of economically viable reserves worldwide. And, importantly, the spiking risk premium in the Middle East is likely to push more capital toward regions previously deemed more risky or marginal.
Venezuela offers a case in point. Its oil industry reopened to Western companies after the U.S. deposed President Nicolas Maduro in January, yet investment in the country has remained tepid given political uncertainty and concerns over the sector’s dilapidated infrastructure.
In a more bullish price environment, however, Venezuela’s vast resources could suddenly appear more appealing – particularly if the relative geopolitical risk gap between Venezuela and the Gulf shrinks.
The energy industry has been through such a geographic reshuffle before. After 2022, the Middle East gained importance when Western companies were forced to exit Russia following Moscow’s full‑scale invasion of Ukraine.
The Iran war now threatens to trigger another realignment - pushing companies to cast their investment nets wider than they have in years. But if the response this time around is to move into riskier or costlier areas, the floor on energy prices is likely going up.
