What is the Strait of Hormuz?
The Strait of Hormuz is a narrow waterway — only 50 kilometers (31 miles) wide — between Iran to the north and Oman/UAE to the south. It connects the Persian Gulf to the Gulf of Oman and the wider Indian Ocean.
It is the most important oil chokepoint in the world.
Why does it matter so much?
Every day before the war, approximately:
| Resource | Share of global trade |
|---|---|
| Oil | 20% of world supply |
| Liquefied natural gas | 25% of global LNG |
| Urea (fertilizer) | 49% of global exports |
| Ammonia (fertilizer) | 30% of global exports |
| Container shipping | Major Asia-Europe route |
There is no alternative route that can handle this volume. Ships must either pass through the strait or reroute around the entire continent of Africa via the Cape of Good Hope — adding weeks and millions of dollars per voyage.
What happened?
After US and Israeli strikes on Iran began on February 28, 2026, Iran retaliated by effectively blocking the Strait of Hormuz using mines, naval vessels, and the threat of anti-ship missiles. This shut down the flow of oil, gas, and goods through the waterway.
The IEA called it the “biggest-ever oil market disruption” — worse than the 1973 oil embargo or the Gulf War.
How does this affect you personally?
The blockade creates a chain reaction that touches almost everything:
Gas prices — 20% of world oil cut off = immediate price spike ($2.98 to $3.57/gal)
Heating oil — Same petroleum supply, up 19% to $5.09/gal
Groceries — Fertilizer shortage (49% of urea blocked) threatens spring planting; shipping costs for food imports soar
Flights — Airspace closures + jet fuel costs = cancelled flights and higher fares
Online shopping — Container ships rerouted around Africa add 2-3 weeks delivery
Electricity — Natural gas supply reduced, pushing up power generation costs
Your job — Higher business costs = potential layoffs, especially in transport, retail, hospitality
Is there any way to fix this quickly?
The IEA released 400 million barrels from strategic reserves, but this only covers ~20 days of lost supply. The real solution requires either:
- Reopening the strait through military action or diplomatic agreement
- A ceasefire that includes guaranteed safe passage for commercial shipping
- Long-term rerouting of global supply chains (expensive, takes years)
Ceasefire talks have begun but no timeline has been announced.
