How Bad Could the Iran Oil Crisis Get?

What It Covers

Energy policy expert Jason Bordoff from Columbia University's Center on Global Energy Policy analyzes the Iran-Strait of Hormuz crisis with Ezra Klein. The Strait carries 20 million barrels daily — 20% of global supply — and its closure represents the largest energy supply disruption ever recorded, exceeding the 1973 Arab oil embargo's 6-7% disruption by a significant margin.

Key Questions Answered

• •Scale of disruption: The Strait of Hormuz closure has removed approximately 10 million barrels per day from global supply — over 10% of the 100-million-barrel daily market. For comparison, the 1973 Arab oil embargo disrupted only 6-7%. Saudi Arabia's pipeline bypass capacity reaches only 4-5 million barrels daily, leaving no realistic workaround to offset the full shortfall at current crisis levels.
• •Nonlinear price risk: Current oil prices above $100 per barrel reflect trader expectations of a quick resolution, not physical market reality. As tankers already loaded pre-crisis reach their destinations over the next two weeks, physical tightness will hit markets harder. Middle distillate products — diesel, jet fuel, heating oil — are already rising faster than benchmark crude prices, signaling industrial economy stress before pump prices fully reflect the disruption.
• •Asymmetric energy weapon: Iran does not need a large military to destabilize global energy markets. Targeting one or two tankers every few days is sufficient to cancel insurance and halt traffic through the Strait. Iran secured 30-day sanctions relief from the U.S. — more than years of nuclear negotiations produced — simply by threatening regional energy infrastructure, demonstrating how low-cost, high-impact this leverage tool has become for weaker powers.
• •Demand destruction threshold: For global oil demand to fall by 10 million barrels per day — the amount needed to rebalance supply — prices must rise high enough to force airlines to idle flights, factories to shut down, and governments in Southeast Asia to mandate work-from-home days and school closures. Countries like Thailand spend 5% of GDP on oil imports alone, leaving minimal fiscal buffer before economic damage becomes severe.
• •China's strategic positioning: China holds approximately 1.5 billion barrels in strategic reserves — built deliberately while the U.S. drew down its own — and has electrified roughly half its new car sales through BYD and other domestic manufacturers. With roughly 50% of its oil and 33% of its LNG transiting the Strait, China faces short-term pain but is structurally better insulated than most economies and positioned as the dominant supplier of clean energy transition hardware globally.
• •Infrastructure damage changes the timeline: If tit-for-tat attacks damage physical energy installations — as Iran's strike on a Qatari LNG facility already demonstrated — recovery timelines shift from weeks to years. Qatar estimates three to five years to repair roughly 20% of the damaged facility. Attacks on Saudi Arabia's Abqaiq installation, Iran's Kharg Island oil terminal, or the Red Sea port of Yanbu could each remove millions of additional barrels per day with multi-year repair horizons.
