Middle East tensions disrupt oil trade, driving sharper increases in jet fuel and diesel prices than crude, tightening global energy supply chains.
Global energy markets are witnessing significant volatility as geopolitical tensions in the Middle East continue to disrupt oil flows and refining operations. The ongoing conflict involving Iran is expected to have a stronger impact on refined petroleum products such as jet fuel and diesel than on crude oil itself.
The situation, which escalated in late February and has now entered its third week, has affected the movement of oil and fuel supplies across key global trade routes. The Strait of Hormuz—a critical corridor for global energy shipments—has experienced major disruptions, leading to a halt in both crude and refined product exports. In addition, several energy installations in the region have reportedly been targeted, adding further pressure on supply chains.
These developments have forced crude producers in the Persian Gulf to cut output, while some refineries have reduced or suspended operations due to logistical and security concerns. Although crude prices have risen sharply, with Brent crude climbing above the $100 per barrel mark after gaining more than 40 percent, the increase in prices for refined products has been even more pronounced.
In parts of Asia, prices of fuels such as jet fuel and diesel have surged significantly, in some cases nearly doubling. Countries including China, Thailand, and South Korea have implemented export restrictions to protect domestic supply and stabilize local markets. While these measures aim to ensure internal availability, they have also contributed to tighter global supply conditions.
A key factor behind the sharp rise in refined fuel prices is the nature of crude oil exported from the Persian Gulf. Around 60 percent of the region’s exports consist of medium and heavy crude grades, which are particularly suitable for producing diesel, jet fuel, and fuel oil. With limited alternative sources for these grades outside the Middle East, global refining systems are facing challenges in maintaining consistent output of these fuels.
The disruption is also expected to impact the petrochemical sector. Naphtha, a crucial refining byproduct used in chemical manufacturing, is likely to face supply constraints. Asia imports nearly half of its naphtha requirements from the Persian Gulf, while Europe relies on the region for about 40 percent of its jet fuel supply. Any prolonged disruption could therefore affect manufacturing activity and transportation sectors across multiple regions.
The current situation highlights how disruptions in crude supply and refining operations can have a more immediate and amplified effect on fuel markets. The sharper rise in jet fuel and diesel prices reflects the sensitivity of downstream supply chains during periods of geopolitical instability.
