The US-Israeli military campaign against Iran, which began on February 28, 2026, has triggered the largest physical disruption to global energy supplies in decades. Unlike previous crises, this shock is not primarily driven by sanctions or rerouting challenges—it stems from a direct blockade and damage to critical infrastructure in the Persian Gulf. As a result, elevated oil and gas prices are likely to persist well beyond any ceasefire, reshaping energy markets, inflation, and global growth for months or even years.
A Physical Supply Outage on an Unprecedented Scale
Roughly 20% of the world’s oil and a similar share of liquefied natural gas (LNG) flows normally pass through the Strait of Hormuz. Iran’s closure of the strait—combined with mining operations and precautionary halts by shippers—has effectively removed around 20 million barrels per day of oil and significant LNG volumes from the market. Gulf producers including Saudi Arabia, the UAE, Kuwait, and Qatar have curtailed output as storage facilities filled up, creating what the International Energy Agency (IEA) has described as one of the most severe supply shocks in modern history.
This contrasts sharply with the 2022 Russia-Ukraine conflict. In that case, Russian production continued, and markets adapted through redirected shipments, alternative suppliers, and coordinated releases from strategic reserves (such as the 180 million barrels drawn down by the United States and allies). Prices spiked but largely normalized within about a year. Today, the disruption is physical and concentrated at a single chokepoint, leaving little room for quick workarounds.
Alternative pipelines through Saudi Arabia and Iraq can handle only 3.5–5.5 million barrels per day at most—far short of closing the gap. For LNG, Qatar’s exports (which account for nearly 20% of global supply) rely heavily on Hormuz routes, with limited spare capacity elsewhere. Global LNG production is already operating near maximum, and building new facilities or expanding pipelines takes years.
Even the IEA’s unprecedented release of 400 million barrels from member countries’ strategic reserves offers only partial relief. Much of this oil is stored inland in the US, Europe, Japan, and South Korea, and transporting it to Asian and European buyers requires secure tanker routes that remain constrained by ongoing security risks.
Infrastructure Damage Turns a Short-Term Shock into a Long-Term Problem
The conflict has escalated beyond a mere blockade. Iranian missiles and retaliatory strikes have damaged or forced shutdowns at key facilities, including Iran’s South Pars gas field and Qatar’s Ras Laffan LNG complex—the world’s largest LNG export hub. Qatar has reported “extensive damage” and fires at Ras Laffan, with officials indicating that full repairs could take up to five years and permanently reduce export capacity by around 17%. Similar impacts have hit sites in Saudi Arabia, the UAE, Kuwait, and Oman.
Oil and gas infrastructure is highly complex and capital-intensive. Restarting damaged plants requires careful safety protocols, specialized repairs, and time to ramp up production. Even partial outages create cascading effects across petrochemicals, fertilizers, electricity generation, and manufacturing. Buyers and traders are now pricing in a lasting risk premium: infrastructure once viewed as secure has proven vulnerable to relatively low-cost missiles and drones, a vulnerability that will not disappear overnight.
Logistical Backlogs and Lingering Threats Delay Recovery
A massive tanker backlog has accumulated on both sides of the Strait of Hormuz. Clearing it, even if shipping resumes at full capacity, will take weeks to months. Restarting shut-in production—particularly LNG trains—cannot happen instantly; facilities must undergo safety checks and gradual ramp-ups.
Moreover, the risk environment has fundamentally changed. Iran-backed groups and potential splinter militias have demonstrated the ability to target energy assets with inexpensive weapons. This means threats could persist even after a main ceasefire, keeping insurance premiums and risk surcharges elevated. Analysts, including those at Goldman Sachs and Wood Mackenzie, warn of sustained upside pressure on prices into 2027, regardless of short-term diplomatic progress.
The Path to Balance: Demand Destruction at Higher Cost
Markets will eventually rebalance, but not through effortless supply restoration. Instead, higher prices will force demand destruction—curtailed industrial activity in energy-intensive sectors like petrochemicals, steel, cement, aviation, and shipping, alongside reduced household mobility and consumption. Energy-importing regions, especially in Asia and Europe, face the brunt of this adjustment, leading to broader inflationary pressures and slower economic growth.
This dynamic echoes but exceeds the 1970s oil shocks in its structural impact. Pre-war Brent crude traded around $70–73 per barrel; prices have since climbed well above $100, with volatility persisting as the conflict enters its fourth week. A return to pre-war levels is unlikely soon because a substantial portion of global supply has been physically removed, and rebuilding or replacing it will outlast any immediate truce.
In summary, the 2026 Iran war has exposed the extreme fragility of the world’s concentrated energy chokepoints in a way that sanctions alone never could. The resulting price shock is structural, not transient. While flows may partially resume, the combination of physical damage, logistical hurdles, and heightened risk perceptions ensures that higher energy costs—and their economic ripple effects—will linger, compelling a painful adjustment across the global economy.
