Do you expect energy costs for your household to rise due to global shipping disruptions?
Middle Eastern conflicts have caused a surge in very large crude carrier (VLCC) vessels in the Gulf of Oman as shipments are rerouted. These geopolitical disruptions have created significant vessel inefficiencies, forcing a shift in how global crude oil is transported.
Why it matters
The rerouting of crude shipments highlights the vulnerability of global energy supply chains to regional conflict. Persistent disruptions and vessel inefficiencies are expected to impact market logistics through the end of the year.
There are currently 30 VLCC vessels operating in the East Mediterranean, while repair efforts on the Saudi East-West pipeline are expected to span 5 weeks. China is considering a 20 million tonne release from its strategic petroleum reserve.
The players
Houthi
This militant group has carried out multiple attacks on maritime and pipeline assets near the Bab el-Mandeb strait.
China
As a major global market for crude imports, the nation is adjusting its refinery operations and strategic reserves in response to shifting economic demand.
The details
Houthi attacks on regional pipeline assets have necessitated a transition to ship-to-ship operations where crude is moved from shuttle vessels to modern tonnage. Simultaneously, China has reduced crude imports and refinery runs due to rising EV penetration and industrial slowing.
Timeline
Regional supply levels were recorded in January and February 2026.
The Western VLCC supply baseline was observed from mid-April to June 2026.
China eased product export controls in August 2026.
Market reports detailing these logistical shifts were published in September 2026.
Current market disruptions are expected to persist through the end of 2026.
Market Landscape
The current rerouting of crude tankers marks a significant shift in energy logistics that challenges established supply routes. This trend mirrors the historical volatility seen in past energy crises, highlighting the industry's ongoing struggle with geopolitical dependency.
Rising transport inefficiencies and potential reserve releases may influence the global price of refined petroleum products at the pump. Consumers and businesses should anticipate continued volatility in energy costs as supply chains adjust to these long-term regional disruptions.
The takeaway
Energy markets remain sensitive to physical security threats in the Middle East that impede standard maritime trade routes. Stakeholders should track pipeline repair timelines and Chinese import data as key indicators for potential stabilization.
