Strait of Hormuz at Risk: India's Oil Import Vulnerabilities After US-Israel Strikes on Iran
The US-Israel joint military operation against Iran on February 28, 2026, has raised immediate concerns over the security of oil transit through the Strait of Hormuz.
Approximately 50% of India's total crude oil imports transit through the Strait of Hormuz — roughly 2.6 million barrels per day (bpd).
Iran has threatened to close the Strait of Hormuz as a retaliatory measure in the event of any military confrontation — a threat it has made repeatedly since 2011.
An Iranian blockade or mining of the Strait would cause immediate supply tightening, oil price spikes, freight and insurance cost surges, and pressure on the Indian rupee and fiscal deficit.
Additionally, more than 13% of India's non-oil exports transit through the Strait of Hormuz region, with disruption also threatening trade routes to West Asia, Europe, and East Africa.
Indian energy security planners are assessing contingency options including alternative suppliers (Russia, US, Latin America) and strategic petroleum reserve deployment.
Strait of Hormuz: Geography and Strategic Significance
The Strait of Hormuz is a narrow waterway connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. It is approximately 167 km long, with the navigable channel only 3.2 km wide in each direction. It is flanked by Iran to the north and the Musandam Peninsula (Oman/UAE) to the south. It is classified as a maritime choke point — a narrow channel through which a disproportionate share of global trade flows. In 2024, approximately 20 million barrels per day (bpd) of oil transited the Strait, representing ~27% of global seaborne oil trade and ~20% of world petroleum liquids consumption. About one-fifth of global LNG trade also transits the Strait (primarily from Qatar).
Iran's ability to threaten the Strait of Hormuz is its most potent leverage point. For India, which depends on the Strait for half its oil imports, a closure scenario would be economically devastating — a direct GS3 energy security question.
India's Oil Import Dependency and Energy Security
India is the world's third-largest oil importer and consumer. In 2023-24, India imported approximately 4.7-5 million bpd of crude oil, with the Middle East accounting for the majority. India's Strategic Petroleum Reserves (SPR) are maintained in underground rock caverns at Visakhapatnam (1.33 MMT), Mangalore (1.5 MMT), and Padur (2.5 MMT) — with a combined capacity of ~5.33 million metric tonnes (MMT), sufficient for approximately 9-10 days of consumption. India's Hydrocarbon Vision 2030 targets reducing oil import dependence through domestic production enhancement and renewables expansion.
India's inability to quickly substitute for Gulf oil at scale makes Strait disruption an acute economic risk — this is standard GS3 energy security material, now activated by a live event.
Maritime Choke Points: Global Strategic Geography
Maritime choke points are narrow passages through which large volumes of global trade must pass — making them strategic leverage points. The world's major choke points include the Strait of Hormuz (Persian Gulf-Arabian Sea), Strait of Malacca (Pacific-Indian Ocean), Suez Canal (Red Sea-Mediterranean), Bab-el-Mandeb (Red Sea-Gulf of Aden), and the Cape of Good Hope (alternative to Suez). India's trade and energy flows are critically dependent on multiple choke points — Hormuz for oil imports, Malacca for exports to Asia, and Bab-el-Mandeb for Europe-bound trade. The Houthi attacks on Red Sea shipping (2023-2025) had already demonstrated choke point vulnerability.
Iran's threat to close the Strait invokes a fundamental UNCLOS question — can a coastal state close an international strait? The answer under UNCLOS is no, but enforcement requires naval power projection.
