A War Viewed Through the Wrong Lens
Much of the American debate surrounding the 2026 war with Iran has been remarkably narrow. Analysis frequently becomes a referendum on Donald Trump. Supporters may interpret developments as vindication of his foreign policy, while critics interpret them as evidence of recklessness, escalation, or strategic failure. In both directions, an extraordinarily consequential geopolitical event is often reduced to another argument about a single political figure. Whatever judgment is ultimately reached about the decisions of the Trump administration, evaluating the conflict primarily through the lens of Donald Trump obscures considerably larger questions raised by the war.
Among those questions is one whose consequences may extend far beyond the Middle East: whether the conflict is fundamentally altering the structure of the global energy system. Eight months into the war, the ultimate outcome remains uncertain, but important changes in energy trade, investment priorities, and national energy strategies are already becoming visible. The question is no longer simply how long the disruption will last, but whether the adaptations it has produced will outlast the conflict itself.
To understand how this conflict could reshape the global energy system, it is worth examining the circumstances that led to the war—and how a military confrontation with Iran developed into an economic disruption extending far beyond the Middle East.

This essay examines an ongoing conflict. Events, estimates, and projections reflect the information available as of the date above and may be revised as the war develops and new data becomes available.
The Road to War
The war did not emerge in a vacuum. In December 2025, protests erupted across Iran amid a collapsing currency, worsening economic conditions, and growing opposition to the Islamic Republic. In January, the government responded with extraordinary violence. Security forces opened fire on demonstrators, killing thousands of protesters and bystanders. A United Nations special rapporteur reported at least 5,000 deaths, while warning that the toll could be considerably higher. Amnesty International described the crackdown as the deadliest period of repression it had documented in decades of research on Iran.
The Islamic Republic was also confronting mounting international pressure over its nuclear and missile programs. The International Atomic Energy Agency had documented Iranian uranium enrichment to 60 percent purity, approaching the approximately 90 percent associated with nuclear weapons. Although the agency had not established that Iran possessed a nuclear weapon, the scale of its enriched uranium stockpile raised serious proliferation concerns. An earlier assessment by the Institute for Science and International Security estimated that, before the June 2025 military strikes, Iran could have produced a crude nuclear weapon not designed for missile delivery within six months or less. Iran also maintained the largest and most diverse missile arsenal in the Middle East, providing Tehran with the ability to threaten American forces and regional adversaries.
On February 28, 2026, the United States and Israel launched a military campaign against Iran. The strikes targeted the country’s military infrastructure, including naval forces, air defenses, missile systems, and facilities associated with its nuclear program. The destruction was extensive. In a subsequent assessment by U.S. Central Command, American commanders reported that 161 Iranian naval vessels had been destroyed, approximately 82 percent of the country’s air-defense missile systems had been disabled, and more than 85 percent of its missile, drone, and naval defense industrial base had been destroyed or severely degraded.
Iran’s nuclear infrastructure had also suffered substantial damage, particularly during the June 2025 strikes against facilities at Fordow, Natanz, and Isfahan. Nevertheless, the full extent of the damage remained uncertain. The International Atomic Energy Agency has been unable to fully account for Iran’s enriched uranium stockpile or verify the condition of all its remaining nuclear capabilities.
Yet the destruction of much of Iran’s conventional military infrastructure has not eliminated its ability to disrupt the global economy. Even with its naval and missile capabilities severely degraded, Iran retains a form of leverage that military superiority alone cannot easily neutralize. That leverage comes not simply from its weapons, but from geography—and its position beside one of the world’s most important maritime chokepoints: the Strait of Hormuz.
The Strategic Power of Geography
Before the conflict, approximately 20 million barrels of petroleum liquids passed through the Strait of Hormuz every day, representing roughly one-fifth of global consumption and one-quarter of internationally traded seaborne oil. More than one-fifth of global liquefied-natural-gas trade also passed through this narrow maritime corridor, making it one of the world’s most strategically important energy chokepoints.
These figures help explain why Iran has historically possessed geopolitical influence disproportionate to the size of its economy. Iran does not control the Strait of Hormuz in the literal sense. Oman borders its southern side, international navigation rights apply, and American and allied naval forces have operated in the region for decades. Nevertheless, Iran’s geography provides it with an extraordinary capacity to threaten commercial passage through one of the world’s most important energy arteries.
That vulnerability has never been distributed evenly. In the first half of 2025, approximately 89 percent of the crude oil and condensate passing through Hormuz went to Asian markets, with China, India, Japan, and South Korea alone accounting for roughly 74 percent of the total. Europe received a much smaller share, approximately 4 percent, while liquefied natural gas passing through the strait accounted for roughly 7 percent of European LNG imports. American exposure was lower still, with petroleum imports through Hormuz representing only about 2 percent of total U.S. petroleum-liquids consumption.
For decades, this arrangement produced an unusual strategic equilibrium. Iran could threaten Hormuz, but actually closing or severely disrupting the strait appeared economically self-defeating. Not only did Iranian exports and imports depend upon it, but a prolonged disruption would also threaten the energy security of China, Iran’s most important oil customer and one of its principal international partners. The prevailing assumption was therefore that Hormuz was most valuable as a weapon that remained largely unused. The threat itself provided leverage without requiring Tehran to endure the enormous economic and diplomatic costs associated with exercising it.
The events of 2026 have challenged that assumption.
From Strategic Threat to Prolonged Disruption
The disruption of commercial traffic through Hormuz has been extraordinary. By the second quarter of 2026, petroleum flows through the strait had fallen by more than three-quarters, accompanied by an even sharper contraction in liquefied-natural-gas shipments. Although oil flows began recovering in subsequent months, renewed attacks on tankers and regional energy infrastructure have repeatedly interrupted that recovery. As of October, shipping remains severely constrained, with the U.S. Energy Information Administration expecting disruptions to Middle Eastern oil exports to persist through the remainder of 2026.
The duration of the disruption is particularly significant. Markets can absorb brief emergencies through strategic inventories, temporary rerouting, and short-term price adjustments. But when disruptions persist for months, they begin influencing long-term contracts, infrastructure planning, capital investment, and national energy strategies. What initially appears to be a temporary supply crisis can gradually become a catalyst for structural change.
That process is already taking shape beyond the Strait of Hormuz. Importers have sought alternative suppliers, tankers have been rerouted, producers outside the Persian Gulf have gained new customers, and governments have begun reconsidering whether decades of prioritizing cost and efficiency have created excessive exposure to geopolitical risk. The adaptations taking place outside the strait may ultimately prove more consequential than the disruption itself.
This creates a paradox for Tehran. The threat of disrupting Hormuz provides leverage precisely because other countries depend upon it. Actually exercising that leverage, however, gives those same countries powerful incentives to reduce their dependence. The longer the disruption continues, the stronger the economic justification becomes for investments designed to make that threat less effective in the future. Iran may therefore be gradually diminishing the very strategic advantage that made Hormuz such a powerful instrument of leverage.
The Beginning of a Global Energy Restructuring
It would be premature to claim that the world has replaced the Strait of Hormuz. Persian Gulf producers possess enormous reserves, well-developed infrastructure, and some of the world’s least expensive oil to extract. Alternative routes are also limited. Before the war, pipelines through Saudi Arabia and the United Arab Emirates could bypass Hormuz with roughly 4.7 million barrels per day of available capacity, compared with more than 20 million barrels ordinarily passing through the strait. The Strait of Hormuz will therefore remain an important part of the global energy system for the foreseeable future.
But the world doesn’t need to abandon Hormuz for its strategic importance to decline. Even a substantial reduction in dependence would make the global economy less vulnerable to disruptions. The objective is not to eliminate the strait from international energy trade, but to ensure that so much of the world’s energy no longer depends on a single narrow passage.
Asian economies have particularly strong incentives to make that adjustment. Japan and South Korea remain heavily dependent on Middle Eastern oil, while India has a more diversified network of suppliers. China benefits from additional pipeline connections, substantial oil reserves, and an increasingly electrified transportation system. Across Southeast Asia, governments are also pursuing investments in renewable energy, regional electricity connections, and strategic fuel reserves to reduce their vulnerability to imported energy. Although their circumstances differ, these countries share an interest in reducing their exposure to disruptions in the Persian Gulf.
The question is whether these adjustments remain temporary responses to the war or become permanent changes in global energy trade. Emergency purchases can end when the crisis subsides, but long-term supply contracts, new pipelines, expanded ports, and additional production capacity are much harder to reverse. A brief disruption can change oil prices; a prolonged disruption can change where countries invest and how they obtain their energy.
The Americas and the Changing Geography of Energy
The Western Hemisphere has emerged as one of the potential beneficiaries of this restructuring. The United States, Canada, Brazil, Guyana, and Argentina possess substantial or expanding production capacity, while other producers in Latin America may also benefit from growing demand for geographically diversified energy supplies.
The implications are particularly important for South America. Brazil has become a major offshore oil producer, Guyana’s petroleum industry has expanded rapidly, and Argentina possesses enormous resources in the Vaca Muerta formation. Some of the adjustment is already visible. According to the International Energy Agency, oil production in Brazil increased by approximately 470,000 barrels per day between February and August 2026, while U.S. production rose by another 520,000 barrels per day. These increases cannot be attributed entirely to the war, but they illustrate how producers outside the Persian Gulf are helping compensate for disrupted supplies. If Asian demand leads to lasting investment in production, pipelines, and export facilities, the region’s role in global energy trade could grow considerably.
The benefits should not be overstated. Oil-importing countries in Latin America can be harmed by higher world prices, and resource wealth does not automatically produce broad economic development. Poor fiscal management, corruption, currency appreciation, or excessive dependence on commodity exports can substantially diminish the benefits of an energy boom. Nevertheless, a lasting shift in Asian oil purchases toward the Americas would represent a meaningful change in international energy trade.
Over time, this shift could build momentum of its own. As Asian countries purchase more oil from the Americas, producers have greater incentives to expand production, pipelines, and export facilities. Those investments, in turn, make it easier for Asian countries to rely less on the Persian Gulf. Once new trade relationships and infrastructure are established, returning to the way things worked before the war becomes increasingly unlikely.
Energy Security Returns to the Forefront
Perhaps the most consequential change produced by the crisis is how governments think about energy security. The importance of reliable energy supplies is hardly new. The oil shocks of the 1970s prompted countries to establish strategic petroleum reserves and invest in alternative energy sources. But decades of relatively dependable international trade made it easier to prioritize lower costs over the risks of relying on distant suppliers and vulnerable shipping routes.
The Hormuz crisis has brought those risks back into focus. The International Energy Agency reported in 2026 that the conflict was already changing investment priorities, with governments and businesses placing greater emphasis on reliable supplies, alternative trade routes, and domestic energy sources. The agency also identified new energy-efficiency policies announced by approximately 20 countries in response to the crisis.
A pipeline that once seemed unnecessarily expensive becomes more attractive when a major shipping route is disrupted. The same applies to strategic reserves, renewable energy, nuclear power, and stronger electricity networks. For countries dependent on imported oil and natural gas, the crisis has strengthened the appeal of producing more electricity from domestic resources. The war hasn’t made energy security important for the first time. It has made the cost of overlooking it much harder to ignore.
Nuclear Power, Renewables, and the Changing Energy Equation
The global shift toward nuclear and renewable energy began well before the war. Countries were already investing in these technologies to reduce carbon emissions, meet growing electricity demand, and strengthen their energy systems. In 2025 alone, the world added 692 gigawatts of renewable power capacity, according to the International Renewable Energy Agency. The Hormuz crisis did not create this transition, but it may provide a powerful reason to accelerate it: energy security.
The scale of investment is already substantial. According to the International Energy Agency, renewable-power investment is expected to reach approximately $665 billion in 2026, compared with more than $80 billion for nuclear power. Spending on electricity grids is projected to approach $550 billion, an increase of nearly 20 percent from the previous year, while battery-storage investment is expected to exceed $100 billion. Much of this expansion was planned before the war, but the crisis has given governments another reason to accelerate it.
Nuclear and renewable energy offer different advantages. Nuclear plants can provide reliable electricity around the clock, while solar and wind power can often be built more quickly and make use of energy resources available within a country’s own borders. Battery storage and stronger electricity grids can help manage the changing output of wind and solar facilities. None of these technologies eliminates the need for international supply chains, but together they offer countries greater control over how their electricity is produced.
The question is whether the Hormuz crisis will cause countries to move faster than they otherwise would have. The IEA projects that renewable electricity generation will grow by more than 8 percent in 2026, overtaking coal as the world’s largest source of electricity, with solar power providing the largest share of new generation. These developments were already underway, but energy security concerns could encourage governments to bring new capacity online sooner, reducing fossil-fuel dependence while supporting further investment in electricity grids, storage, and manufacturing.
Nuclear power presents a longer-term opportunity. Building reactors generally requires more time and money, but sustained construction can help countries develop the skilled workers, manufacturing capacity, and experience needed to complete future projects more efficiently. South Korea, with its established nuclear industry and experience exporting reactors, illustrates how a sustained expansion could strengthen both domestic energy security and international markets. The significance of accelerating these investments lies not simply in adding generating capacity sooner, but in developing industries capable of supporting continued expansion.
Expanding nuclear and renewable energy, alongside electrification, can reduce dependence on imported fossil fuels while also advancing climate objectives. This creates an alignment of interests: governments seeking to reduce emissions and those concerned about energy security have different motivations, but both have reasons to invest in the same technologies.
The Climate Consequence Is Conditional
The restructuring of global energy trade could improve energy security without necessarily benefiting the climate. Replacing Saudi oil with supplies from Brazil, Guyana, Canada, or the United States reduces dependence on the Persian Gulf, but burning that petroleum still produces carbon dioxide. Longer shipping routes can also increase transportation emissions.
The greater environmental benefit comes when countries reduce their consumption of fossil fuels rather than simply changing suppliers. Electrification, renewable energy, nuclear power, and improved energy efficiency can all contribute to that transition. But the outcome is not guaranteed. Energy shortages can also encourage greater use of coal and other fossil fuels, potentially increasing emissions. Whether the crisis ultimately benefits the climate will depend on which investments endure after the war.
A Different Energy Order
The world has already demonstrated that it can adapt to a major disruption of Hormuz. The more important question is whether those adjustments will last. Emergency oil purchases, temporary shipping arrangements, and withdrawals from strategic reserves can help countries manage a crisis, but lasting change requires something more: new supply relationships, expanded energy infrastructure, and investments that reduce dependence on vulnerable shipping routes.
In the end, the war may prove to have accelerated these changes. Asian economies have new incentives to diversify their petroleum suppliers, while producers in the Americas and elsewhere have opportunities to expand into new markets. At the same time, nuclear power, renewable energy, and electrification offer countries another way to reduce their dependence on imported fossil fuels. These developments will take years, and some of the adjustments made during the crisis will undoubtedly prove temporary. The real measure of change will be whether the investments made in the coming years leave the world less dependent on Hormuz than it was before the war.
None of these potential gains would erase economic damage or instability caused by the conflict. Nevertheless, the crisis has exposed a vulnerability that governments and businesses can no longer easily dismiss. For decades, Iran’s proximity to the Strait of Hormuz gave it extraordinary influence over the global economy. By disrupting that passage on an unprecedented scale, Tehran may also have given the rest of the world a powerful incentive to diminish that influence.
If those changes endure, the war’s most consequential economic legacy may ultimately be found far beyond the Middle East: in new energy partnerships across the Americas, expanded nuclear and renewable power, increasingly electrified economies, and a global energy system less dependent on any single maritime chokepoint.
