Japan
4th largest oil consumer
World's most Hormuz-dependent major economy. Relies on imports for nearly all oil supply — any closure is an existential supply crisis with downstream manufacturing and power generation impacts within days.
KEY SUPPLIERS: Saudi Arabia · UAE · Kuwait · Qatar · Iran
🇰🇷
South Korea
5th largest oil importer
Imports virtually all of its oil. A Hormuz disruption poses an existential threat to energy security — petrochemicals, power generation, and transport would face critical shortfalls within weeks.
KEY SUPPLIERS: Saudi Arabia · Kuwait · Iraq · UAE · Qatar
🇮🇳
India
3rd largest oil importer
Rapidly growing energy demand with limited diversification. Mid-range dependency but enormous absolute volumes — rising Russian imports offer partial buffer, but Gulf sources remain dominant.
KEY SUPPLIERS: Iraq · Saudi Arabia · UAE · Kuwait · Russia

China
World's largest oil importer
Brings in over 10 MBpd of imports. While less dependent in percentage terms, the absolute volume makes any disruption a national security emergency with immediate strategic reserves deployment expected.
KEY SUPPLIERS: Saudi Arabia · Russia · Iraq · Angola · Iran
🇪🇺
Europe (EU-27)
Indirect exposure via price spikes
Less directly dependent than Asia, but highly exposed to global oil price spikes. Stagflation risk and energy-intensive industry shutdowns are primary concerns; diversified supply mix provides a meaningful buffer.
KEY SUPPLIERS: Norway · US · Kazakhstan · Saudi Arabia · Iraq

Australia
Critically thin strategic reserves
Low direct dependency but among the most vulnerable due to critically thin strategic reserves — mostly commercial stocks with minimal government buffer — making any extended disruption disproportionately dangerous.
KEY SUPPLIERS: Malaysia · UAE · US · Indonesia · Singapore
🇺🇸
United States
Energy independent + military role
Largely energy independent — imports minimal oil through the Strait. However, oil is priced globally, so any Hormuz disruption causes domestic price increases. Plays the central military and diplomatic role in strait security.
KEY SUPPLIERS: Canada · Mexico · Saudi Arabia · Colombia · Brazil

NET EXPORTER — REVENUE AT RISK
Gulf states are the producers most directly affected — their vulnerability is revenue loss, not supply disruption. Saudi Arabia and UAE have bypass pipelines; all others are fully trapped. A closure collapses state budgets within months.
