Iran War: Disrupting Global Energy and Commodity Supplies

Jet fuel has emerged as the primary indicator of a deepening global energy crisis triggered by the ongoing war in Iran. While broader energy markets are feeling the impact, the volatility in aviation fuel reflects a larger systemic shock to the products essential for global transportation and commerce.

The energy crisis is driven by a geopolitical shock in the Middle East following strikes on Iran by the United States and Israel. These military actions have disrupted supply chains out of the Persian Gulf, leading to a sharp increase in the prices of both oil and gas.

The Closure of the Strait of Hormuz

Central to the current supply crisis is the effective closure of the Strait of Hormuz. This corridor is a critical global energy artery, responsible for transporting approximately one-fifth of the world’s liquefied natural gas (LNG) and oil trade.

According to a report by Oxford Economics published April 1, 2026, the disruption of this channel has stranded approximately 10 million barrels of oil exports per day. While some rerouting has been attempted, it has only been partially successful in mitigating the loss.

This supply contraction has pushed the price of Brent crude above $100 per barrel. Market analysts expect prices to continue rising in the near term as the logistical constraints persist.

Shifting Commodity Outlook for 2026

At the beginning of 2026, commodity markets were projected to remain relatively stable, with modest demand growth and robust supply suggesting weaker prices. However, the conflict in Iran has reversed this outlook.

Geopolitical disruption has replaced traditional supply and demand dynamics as the dominant driver of price formation. Oxford Economics reports that more than two-thirds of all commodities are now expected to record price increases throughout 2026.

The impact extends beyond crude oil. The World Economic Forum has identified at least nine different commodities impacted by the crisis in the Strait of Hormuz, indicating a broad repricing across energy, metals, and agricultural markets.

Global Economic Consequences

The scale of the supply reduction has created what Reuters described on March 21, 2026, as a nightmare scenario for the global energy system. The war has slashed supply to a degree that is forcing nations to either pay significantly higher prices or cut their overall energy consumption.

The volatility in jet fuel is particularly significant because it serves as a harbinger for the wider transportation sector. As a refined product, its price fluctuations signal how the raw crude oil shortage is filtering through refineries and impacting the movement of goods and people globally.

The current market environment is characterized by precautionary behavior and severe logistical constraints, which are outweighing the previous expectations of a balanced energy market. This shift marks one of the most significant forecast revisions for global commodities in recent years.
