A single well-placed missile hitting a tanker in the Strait of Hormuz could disrupt roughly one-fifth of the world’s daily oil flows, turning the Israel-Iran war into a broader global energy emergency. The narrow waterway off Iran’s southern coast carried approximately 20 million barrels of oil per day in 2024, and the International Energy Agency has reported a near-halt in tanker movements since hostilities began in March 2026. What separates this crisis from past disruptions is the speed at which reported damage to Gulf energy infrastructure has compounded the shipping freeze, threatening higher fuel costs for consumers and industries on every continent.
Twenty Million Barrels a Day at Risk
The Strait of Hormuz is the world’s most consequential oil chokepoint, and the numbers explain why. Oil flows through the strait averaged about 20 million barrels per day in 2024, representing roughly 20% of global petroleum liquids consumption. Even a temporary inability to transit the strait raises shipping costs and ripples through world energy prices, a dynamic that analysts have modeled for decades but are now watching play out in real time.
The crisis extends well beyond crude oil. About one-fifth of global liquefied natural gas trade also passed through the strait in 2024, with Qatar alone exporting approximately 9.3 billion cubic feet per day of LNG through the waterway. The majority of that gas heads to Asian buyers, meaning a prolonged closure would hit power generation and industrial output across East and South Asia hardest. Countries such as Japan, South Korea, and India have limited short-term alternatives for replacing Qatari LNG volumes if the strait stays blocked, and global gas markets were already tight before the current conflict.
Natural gas storage can buffer short-lived disruptions, but inventories are finite and unevenly distributed. Data from the U.S. Energy Information Administration’s weekly storage reports show how quickly stocks can draw down during periods of high demand. If Asian and European buyers must compete for diverted cargoes while drawing on storage, prices could spike far beyond the levels seen during previous winters, with knock-on effects for electricity bills, fertilizer costs, and heavy industry.
Attacks on Refineries and LNG Plants
Iran’s retaliatory strikes on Gulf energy assets after Israeli attacks have moved the crisis from a theoretical risk to a potential material supply shock, according to Reuters reporting on damage to key facilities. Drone and missile attacks struck refineries and LNG plants in Saudi Arabia and Kuwait, and multiple key facilities have been damaged or shut down. The physical destruction of processing capacity means that even if tanker traffic resumed tomorrow, the oil and gas those ships would carry may not be available for weeks or months, as operators assess damage, secure spare parts, and rebuild.
In a March 19, 2026 Reuters video report, analyst Viktor Zhdannikov described the attacks on Gulf energy assets as “very significant,” underscoring the risk of real supply disruptions rather than mere market jitters. What makes this round of strikes different from the 2019 attacks on Saudi Aramco’s Abqaiq facility is the breadth of targets: rather than a single complex, Iran hit infrastructure across multiple countries simultaneously. That dispersion reduces the region’s ability to reroute production through undamaged facilities and complicates efforts by Gulf producers to act as swing suppliers.
Refineries are particularly vulnerable because they sit at the chokepoint between crude extraction and final products like gasoline, diesel, and jet fuel. Damage to catalytic crackers, distillation towers, or control systems can sharply curtail output even if crude continues to flow from the fields. LNG plants face similar fragilities: liquefaction trains are capital-intensive, highly engineered systems that cannot be quickly replaced or replicated elsewhere. In this conflict, both types of facilities are now targets, magnifying the potential for prolonged shortages.
Tanker Traffic Grinds to a Halt
The International Energy Agency’s March 2026 Oil Market Report documented a near-halt in tanker movements through the Strait of Hormuz, with benchmark crude prices surging since hostilities began. The IEA also noted a coordinated emergency release totaling 400 million barrels from strategic reserves, an effort aimed at cushioning the blow and reassuring markets. That release buys time but does not solve the underlying problem: if the strait remains effectively closed, reserves will drain faster than they can be replenished, and rebuilding stocks later will itself support higher prices.
Most coverage has focused on the oil price spike, but the less visible danger lies in the insurance and shipping markets. When underwriters refuse to cover vessels transiting a war zone, or when premiums spike to prohibitive levels, tanker owners simply reroute or anchor. The result is the same as a physical blockade, even without a single mine in the water. A Congressional Research Service brief on the Hormuz chokepoint highlights the risks posed by mines and missiles alike, and notes the limited practicality of alternative routes and the constraints facing U.S. and partner naval forces trying to keep the strait open.
Alternative pipelines across Saudi Arabia and the United Arab Emirates can bypass Hormuz for a fraction of regional exports, but not at the volumes needed to replace full strait flows. Moreover, some of those lines feed into the very refineries and export terminals that have now been damaged. The combination of shipping paralysis and onshore destruction leaves producers with few options other than shutting in production, which can itself harm reservoirs and delay future supply.
A Crisis Compared to the 1970s Oil Shocks
Fatih Birol, executive director of the International Energy Agency, has drawn a stark comparison. He said the Iran war energy crisis is on par with the 1970s oil shocks and the fallout from Russia’s invasion of Ukraine, warning that the growing crisis could be seriously compounded if not properly understood by world leaders. That framing puts the current disruption in the same category as the 1973 Arab oil embargo and the 1979 Iranian Revolution, events that reshaped the global economy for a decade and left lasting scars on inflation and energy policy.
The parallels are striking. As in the 1970s, a geopolitical conflict in the Middle East has collided with tight global markets and limited spare capacity. However, the world is now more dependent on just-in-time supply chains and complex cross-border trade. Many countries have built strategic petroleum reserves since the 1970s, but they are calibrated for temporary shocks, not an open-ended conflict that simultaneously threatens extraction, processing, and transportation.
Edward Fishman, a senior fellow and director of the Maurice R. Greenberg Center at the Council on Foreign Relations, has described the conflict’s economic fallout as a “geoeconomic firestorm” engulfing shipping. That assessment points to a feature of this crisis that the 1970s precedents lacked: the modern global economy is far more interconnected, and disruptions in one shipping lane can cascade through container traffic, bulk commodities, and manufacturing supply chains worldwide. Higher bunker fuel costs translate into more expensive food, consumer goods, and industrial inputs, amplifying the initial energy shock.
Global Fallout and Policy Choices
The immediate impact of the Hormuz crisis is felt at the pump and on utility bills, but the deeper consequences will depend on how governments respond. Coordinated reserve releases and temporary fuel tax relief can soften the blow to households, yet they cannot fully offset the loss of physical supply if the conflict drags on. Major importers face hard choices between bidding up prices to secure cargoes, imposing rationing, or accelerating demand-reduction measures such as efficiency standards and work-from-home policies.
For producers outside the Gulf, the crisis presents both opportunity and risk. Higher prices incentivize investment in new fields and export infrastructure from the Americas to Africa, but long lead times and regulatory hurdles mean those barrels will not arrive in time to ease the current crunch. At the same time, a disorderly price spike could trigger recessions in key consuming regions, ultimately eroding demand and undermining those very investments.
Longer term, the shock is likely to intensify debates over energy security and the pace of the transition away from fossil fuels. Some policymakers will argue for expanding domestic oil and gas production and building more strategic storage, while others will see the crisis as proof that dependence on seaborne hydrocarbons is an enduring vulnerability. Whichever path they choose, the events in the Strait of Hormuz have made one reality unmistakable: in a world still powered by oil and gas, a single chokepoint can hold the global economy hostage.
