Title: Petrol Prices Surge Amid Rising US‑Iran Tensions, Shaking Global Markets

Summary: US petrol prices have climbed to $4.00 per gallon (3.78 L), marking the second consecutive week of higher costs at the pump and sending ripples through energy markets worldwide.

Introduction:
The latest spike in fuel costs comes as diplomatic friction between the United States and Iran intensifies, prompting traders to reassess supply risks in the Middle East. Analysts note that even modest disruptions to oil flows from the Persian Gulf can translate into noticeable price jumps at U.S. stations, especially when inventories are already tight.

Key Developments:
- The national average for regular gasoline rose 12 cents to $4.00 per gallon on Monday, according to the U.S. Energy Information Administration.

First, geopolitical tension adds a risk premium to crude contracts, as investors price in the possibility of reduced Iranian output. Second, domestic demand remains robust heading into the summer travel season, keeping inventories below the five‑year average.
