Southeast Asia & the Strait of Hormuz.
Southeast Asia is the most heterogeneous case in this set. Thailand and the Philippines are nearly as Hormuz-dependent as Japan; Malaysia and Indonesia are partial domestic producers and look more like the United States in import-share terms. Singapore's role as the world's largest bunkering hub means the price-discovery for marine fuel oil happens here first, regardless of where the disruption lands. Strategic reserves across the region are the thinnest of any importing bloc — coordination at the ASEAN level remains structural rather than operational. The double chokepoint geometry — Hormuz, then Malacca — means cargoes that have already paid the Cape detour still face a second pinch point before delivery, which compresses regional refining margins disproportionately.

Key facts
- Diverse mix: Singapore, Thailand, Philippines, and Vietnam are net importers; Malaysia and Indonesia are partial producers.
- Hormuz dependency varies sharply: Thailand and the Philippines are 60%+; Malaysia and Indonesia under 20%.
- Singapore is the world's largest bunkering hub — Hormuz disruption flows through marine fuel oil markets first.
- Strategic reserves are thin compared to OECD peers; ASEAN-level coordination remains aspirational.
- The Strait of Malacca chokepoint compounds Hormuz risk for cargoes that have already paid the Cape detour.
Vulnerabilities
- Reserve cushion is the thinnest of any major importing region.
- Singapore bunkering exposure passes through to global container freight rates.
- Refined-product imports for Vietnam and the Philippines depend on Korean and Indian refiners — second-order exposure.
- Indonesia is a major LPG importer; Qatari and Saudi cargoes are the primary source.
Mitigations
- Indigenous Malaysian and Indonesian crude provides partial regional substitution.
- Russian crude diversification has accelerated for Indonesia and Vietnam since 2022.
- Singapore-managed marine fuel pricing absorbs early-stage disruption signals.
- Long-term LNG contracts with Australia and the US (Thailand, Singapore, Philippines).
Historical context
Southeast Asia's exposure is a story of geography stacked twice. Cargoes from the Gulf cross Hormuz, then cross the Strait of Malacca, then reach refining hubs that re-export to neighbouring nations. The 1997 Asian financial crisis reset assumptions about energy import dependence; subsequent diversification has been partial and uneven across the bloc.
