🚢 What Is the Strait of Hormuz?
The Strait of Hormuz is a narrow waterway between the Persian Gulf and the Gulf of Oman. It’s only about 21 miles wide at its narrowest point, but it handles 20% of the world’s oil supply—about 17.3 million barrels per day.

Fact | Value |
---|---|
Width at narrowest point | 21 miles |
Daily oil flow | 17.3 million barrels (2023 data) |
Global oil supply through it | ~20% |
Main exporters | Saudi Arabia, Iran, UAE, Iraq |
Key importers | India, China, Japan, South Korea |
🧨 Why Is the Strait Always in Danger?
The Strait of Hormuz sits in a region often hit by tensions—especially between Iran and Western powers. Threats of war, drone strikes, and tanker attacks have occurred frequently. Iran has often warned of blocking the strait in retaliation for sanctions.
This brings us to the burning question …Strait of Hormuz Disruption
📈 How Does Strait of Hormuz Disruption Affect Oil Supply?
If even one missile hits a tanker or a naval blockade occurs:
- Tankers stop moving – Insurance goes up, and so does risk.
- Supply drops suddenly – Even a 10% drop causes price surges.
- Alternative routes are expensive and longer – No quick fix.
Example: In 2019, when two tankers were attacked near the Strait, oil prices jumped by 4% in one day!
📊 Real Data: Oil Prices During Tension Periods, Strait of Hormuz Disruption
Year | Event | Oil Price Jump |
---|---|---|
2019 | Tanker attacks | +4% |
2020 | US-Iran tension (Soleimani) | +6.5% |
2023 | Drone threats near Hormuz | +3% |
🏭 What Happens Globally After a Strait of Hormuz Disruption?
The disruption of this key oil artery could trigger:
- Higher petrol, diesel, and LPG prices globally
- Inflation in energy-dependent economies
- Slower economic growth in developing nations
- Stock market volatility in oil-heavy sectors

🧠 Simple Example
Imagine if India imports 60% of its crude through this route. If prices go up by $10 per barrel, the government may have to raise fuel prices or cut subsidies—either way, you pay more.
🤝 Who Gains and Who Loses?
Let’s visualize:
Stakeholder | Gains 💰 | Loses 💸 |
---|---|---|
US shale oil companies | Higher profits | |
Russia (alternate seller) | More market share | |
Oil-importing countries | Rising fuel bills | |
Shipping companies | Higher insurance, longer routes | |
Global consumers | Expensive transportation, inflation |
A crisis in the Strait of Hormuz helps some economies and devastates many.
❗ But Why Hasn’t Iran Closed the Strait Yet?
Despite threats, Iran hasn’t closed it because:
- It exports oil through it too.
- Blockade invites military response from US/NATO.
- Global backlash and economic isolation.

🛡️ What Are Countries Doing About It?
To avoid overdependence, major oil importers are:
- Building Strategic Oil Reserves
- Importing from diverse routes (e.g., Africa, Latin America)
- Investing in renewables
Country | Strategy |
---|---|
India | 74 days of strategic reserves |
China | Expanding pipeline routes inland |
Japan | Oil diversification + solar push |
🌐 Future Outlook: Are We Still at Risk?
Yes, Strait of Hormuz disruption will always remain a global risk as long as:
- Conflicts in the Middle East persist
- Oil demand stays high globally
- No alternative route matches its scale

But global energy transition to renewables and more peaceful diplomacy could reduce this threat gradually.
🧠 Conclusion: What Should You Take Away?
We began with a simple question from a curious kid about petrol prices. The answer lies halfway across the globe in a 21-mile stretch of water that carries the world’s oil hopes.
Understanding Strait of Hormuz disruption is not just for oil experts or analysts—it impacts your wallet, fuel bill, and food prices.
The world is preparing, but risk remains. Stay aware, stay informed.
