From the latest data and news, we can estimate how much oil has risen since the Iran war began and what it means for the global economy.
1. Oil price before the Iran war vs now
Before the war (late Feb 2026):
Brent crude ≈ $70?$72 per barrel �
Databoks +1
WTI crude ≈ $65?$67 per barrel
Early days after the war (March 1?4):
Brent ≈ $77?$81 �
Databoks +1
Now (according to the screenshot / current market):
WTI ≈ $115
Brent ≈ $116
Total increase since war started
Oil Benchmark
Before War
Now
Increase
Brent
~$71
~$116
+$45
WTI
~$66
~$115
+$49
➡ ️ Oil has risen about 60?70% in a few weeks.
This is one of the largest war-driven oil spikes since the 2008 financial crisis.
2. Why oil exploded so fast
The Iran war affects oil markets because of one key location:
Strait of Hormuz
~20% of global oil supply passes through it �
AP News +1
Tankers are being blocked or delayed
Gulf countries are cutting production
Even fear of disruption pushes traders to bid oil higher.
3. Economic shock to the world
High oil acts like a global tax on the economy.
Energy cost shock
When oil rises:
Transport cost ↑
Electricity cost ↑
Food cost ↑
Manufacturing cost ↑
Example chain reaction:
Copy code
Oil ↑
Transport ↑
Food price ↑
Inflation ↑
Interest rates ↑
Economy slows
4. Impact on US and global stock markets
News already shows markets reacting strongly.
Asian markets dropped sharply
Global investors fear recession �
AP News
Some stock markets fell 4?7% in one day �
The Australian
Stocks that usually fall
Airlines
Transport
Manufacturing
Consumer companies
Technology
Stocks that rise
Oil companies
Defense companies
Commodity producers
5. Risk of global stagflation
If oil stays above $100?120 for months:
You get stagflation:
High inflation
Low economic growth
High interest rates
This happened before during:
1973 oil crisis
1979 Iran revolution
Both triggered global recessions.
6. Social impact (what ordinary people feel)
If oil stays high for long:
United States
gasoline prices surge
consumer spending drops
political anger rises
Europe
energy inflation
slower economic growth
Asia
import costs explode
weaker currencies
Countries like:
Japan
India
South Korea
Singapore
are very sensitive to oil prices because they import energy.
7. Worst-case scenario if the war expands
If the Strait of Hormuz fully closes, analysts estimate:
Possible oil price:
$150?$200 per barrel
Then we may see:
global recession
stock markets crash
central banks trapped by inflation
✅ Summary
Item
Result
Oil before war
~$70
Oil now
~$115
Increase
~60?70% surge
Economic effect
inflation shock
Market effect
volatility / stock declines
Worst risk
global stagflation
💡 If you want, I can also show you something very interesting:
Why some investors (including Warren Buffett?style investors) actually make huge money during oil shocks while the rest of the market crashes.
The strategy is quite counter-intuitive.
