Global oil prices settled above $100 per barrel for the first time since August 2022, driven by escalating tensions in the Persian Gulf. Iran's new leadership announced plans to maintain the closure of the crucial Strait of Hormuz while continuing attacks on neighboring countries. The International Energy Agency called the conflict the biggest supply disruption in history.

The Strait of Hormuz is a critical chokepoint for global oil shipments, with roughly 20% of the world's petroleum liquids passing through the narrow waterway. Iran's aggressive stance threatens to severely disrupt global energy supplies at a time when markets are already strained. The blockade strategy represents a dramatic shift in Iran's approach to regional conflicts.

Crude oil futures surged past the $100 threshold, marking the highest settlement prices in over 18 months. Energy markets have been volatile throughout the escalating Middle East crisis, with traders pricing in significant supply risk premiums. The price spike affects everything from gasoline costs to heating bills globally.

The sustained closure threatens to reshape global energy flows and force importers to seek alternative supply routes at higher costs. Major economies dependent on Gulf oil imports face potential energy security challenges. Market analysts warn that prolonged disruption could push prices even higher and accelerate inflation concerns worldwide.
