How the Hormuz Crisis Reshaped Global Oil Flows

The $63-to-$126 Story

In less than two weeks, the global energy landscape changed more dramatically than at any point since the 1973 Arab oil embargo. On February 28, 2026, joint US-Israeli air strikes on Iran — dubbed Operation Epic Fury — triggered a chain of events that sent Brent crude from a relatively stable $63/bbl to a peak of $126/bbl by March 8, before settling around $107/bbl in mid-March.

This wasn't a gradual escalation. It was a shock — the fastest oil price doubling in modern history, driven by the effective closure of the Strait of Hormuz, the narrow waterway through which roughly 20% of the world's seaborne oil trade flows every single day.

What Flows Through Hormuz

The Strait of Hormuz is not just another shipping lane. It is the single most critical chokepoint in global energy infrastructure:

~20 million barrels/day of crude oil transit — roughly 20-27% of all seaborne oil trade
3.3 million barrels/day of refined petroleum products (diesel, gasoline, jet fuel)
1.5 million barrels/day of LPG (liquefied petroleum gas)
~80 million tonnes/year of LNG (liquefied natural gas), primarily from Qatar
An average of ~45 tankers pass through the strait daily under normal conditions

The producers who depend on this route include Saudi Arabia, UAE, Iraq, Kuwait, Qatar, and Iran itself. The disruption doesn't just affect crude oil — it simultaneously hits refined fuels, cooking gas, and natural gas supplies, creating a multi-vector energy crisis.

The Crisis Timeline

| Date | Event | Oil Price | |------|-------|-----------| | Jan 2026 | US-Iran tensions escalate | Brent ~$63-65/bbl | | Feb 15-20 | Iran pre-conflict stockpiling — exports surge 3x | Market nervousness | | Feb 28 | Operation Epic Fury — US & Israel strike Iran | Immediate spike | | Mar 1 | Iran retaliates — missiles on US bases, Gulf states. IRGC warns "no ship through Hormuz" | Brent ~$80/bbl | | Mar 4 | Iran officially declares Strait of Hormuz closed | Tanker traffic drops ~70% | | Mar 8 | Brent crosses $100/bbl for first time in 4 years | $126/bbl peak | | Mar 11 | IEA unanimously agrees to release 400M barrels from SPR | Temporary relief | | Mar 12 | 21 confirmed Iranian attacks on merchant ships | Sustained disruption | | Mar 16-17 | US strikes on Kharg Island (Iran's main export terminal) | Brent $102-109/bbl | | Mar 19-21 | Ongoing volatility, Houthis resume Red Sea attacks | Brent ~$107/bbl |

Who's Most Exposed?

The impact of the Hormuz closure is not evenly distributed. Some countries face near-total disruption of their energy imports:

South Asia — The Hardest Hit

Pakistan: 99% of LNG imports come from Qatar and UAE — both transit Hormuz. Pakistan faces potential power grid collapse and industrial shutdown.
Bangladesh: 72% of LNG imports flow through the strait. Already facing chronic energy shortages.
India: 60% of oil imports come from the Middle East, and 53% of LNG imports transit Hormuz. India has pivoted aggressively to Russian crude, but pipeline capacity limits the substitution.

East Asia — The Largest Volumes

China: The world's largest crude importer. Buys 80%+ of Iranian oil exports. Has the largest strategic reserves (~1 billion barrels) but faces sustained supply chain disruption.
Japan: Heavily dependent on Middle Eastern oil and Qatari LNG. The crisis has accelerated nuclear restart discussions.
South Korea: Combined with Japan, China, and India, these four countries account for 69% of all crude flows through the strait.

Europe — Qatar LNG Vulnerability

12-14% of EU LNG comes from Qatar through Hormuz
The disruption compounds existing energy security concerns from the Russia-Ukraine war
European gas prices have spiked in sympathy with oil

Alternative Routes and Their Limits

There are only a handful of alternatives to Hormuz transit, and all have significant constraints:

Saudi East-West Pipeline (Petroline): 7 million b/d capacity connecting eastern oil fields to the Red Sea port of Yanbu. But Saudi Arabia shut in significant production due to storage overflow, and the pipeline can't handle the full volume normally transiting the strait.
Abu Dhabi Crude Oil Pipeline (Fujairah): Bypasses Hormuz by sending UAE crude to Fujairah port on the Gulf of Oman. Capacity is ~1.5 million b/d — a fraction of total transit.
Cape of Good Hope rerouting: Tankers can avoid the Persian Gulf entirely by sourcing from West Africa or redirecting via the Cape. This adds 2-3 weeks to transit time and significantly increases shipping costs.
Russian crude to Asia: India and China have accelerated purchases of Russian crude via pipeline and Pacific routes, but volumes are limited by infrastructure.

The IEA Response: Is 400M Barrels Enough?

On March 11, the International Energy Agency unanimously agreed to release 400 million barrels from member countries' strategic petroleum reserves — the largest coordinated release in IEA history.

For context:

Global oil consumption is approximately 102 million barrels/day
400M barrels covers roughly 4 days of total global consumption
Or approximately 20 days of normal Hormuz transit flows
The US Strategic Petroleum Reserve holds ~415 million barrels (down from 714M in 2020)

The SPR release provided temporary price relief — Brent dropped from $126 to the low $100s — but it's a finite resource that buys time, not a solution to sustained supply disruption.

Russia's Advantage — The Sanctions Reshuffle

The Hormuz crisis has inadvertently strengthened Russia's position in global energy markets:

India has dramatically increased Russian crude imports, with Russian oil now accounting for over 40% of India's imports — up from 2% before the Ukraine war
China has deepened Russian energy ties, with pipeline gas deliveries at record levels
Russian crude (Urals blend) trades at a narrower discount to Brent as alternative supplies become scarcer
Countries previously pressured to reduce Russian energy purchases now have little choice but to maintain or expand these flows

What This Means for the Energy Transition

The Hormuz crisis is a brutal reminder of the vulnerability inherent in fossil fuel dependence:

Energy security is not just a policy concept — it's a daily operational reality for billions of people. Countries with diversified energy sources and significant renewable capacity are better buffered against supply shocks.
Renewables are a strategic asset, not just an environmental choice. Countries with high renewable electricity shares (like Brazil at 83% or Norway at 98%) face minimal direct impact from oil price spikes on their power sector.
The "last mile" of fossil fuels will be the hardest — even countries with high renewable electricity still depend on oil for transport, petrochemicals, and heating. Electrification of transport is an energy security imperative, not just a climate one.
Strategic reserves need rethinking — the current global SPR system was designed for short disruptions, not sustained closure of a major chokepoint. The gap between reserve capacity and potential disruption duration is widening.
