Refiners Adjust Sourcing as War Rattles Markets

Why It Matters

The shift safeguards Thailand’s fuel security amid geopolitical turbulence and signals a broader realignment of Asian energy supply chains away from vulnerable chokepoints.

Key Takeaways

• Crude imports drop from 70% Middle East to 30%
• Refineries add West African and US crude sources
• Floating storage expanded, raising oil stockpiles above normal
• PTT cuts LNG from Gulf of Thailand to 54%
• Imported LNG now 35% of Thailand's total supply

Pulse Analysis

The escalation of hostilities in the Middle East, highlighted by the closure of the Strait of Hormuz, has rattled global oil markets and forced import‑dependent nations to rethink supply routes. Thailand, which sources 90% of its crude abroad, historically leaned heavily on Middle Eastern shipments. The sudden disruption has underscored the vulnerability of relying on a single maritime corridor, prompting analysts to watch how regional refiners adapt to maintain stable fuel supplies.

In response, Thai refiners have rapidly diversified their feedstock portfolio. Crude purchases now flow from West African producers and U.S. exporters, reducing Middle Eastern dependence to roughly one‑third of total imports. Operators have also accelerated procurement cycles, bolstered floating storage capacity, and lifted refined‑oil inventories above typical levels. These precautionary steps create a strategic buffer, ensuring that downstream demand can be met even if geopolitical tensions persist or shipping lanes remain constrained.

The broader energy landscape in Southeast Asia is also shifting. PTT Plc, Thailand’s national oil and gas champion, is curbing LNG imports that once arrived via the Gulf of Thailand, dropping its share to 54% and boosting reliance on overseas LNG to 35% of total supply. This pivot reflects a regional trend toward supply diversification and heightened emphasis on energy security. As the conflict endures, Thailand’s proactive adjustments may serve as a template for other import‑dependent economies seeking resilience against geopolitical shocks.
