What Happened
- 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).
- Location: Between Persian Gulf and Gulf of Oman
- Flanked by: Iran (north), Oman + UAE's Musandam Peninsula (south)
- Length: ~167 km; navigable channel: ~3.2 km per direction
- Oil transit (2024): ~20 million bpd — ~27% of global seaborne oil trade
- LNG transit: ~20% of global LNG trade (mainly Qatari LNG)
- Key exporters transiting: Saudi Arabia, UAE, Kuwait, Iraq, Qatar, Iran itself
- Alternative pipelines: Saudi Arabia (East-West Pipeline: 5 mbpd) and UAE (Habshan-Fujairah: 1.5 mbpd) — insufficient to compensate for full closure
Connection to this news: 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: 3rd largest oil importer globally (after US and China)
- Crude imports (2023-24): ~4.7-5 million bpd
- Middle East share: ~50-60% of total imports
- Strait of Hormuz share of India's imports: ~50% (~2.6 million bpd)
- Strategic Petroleum Reserve (SPR) locations: Visakhapatnam, Mangalore, Padur
- SPR combined capacity: ~5.33 MMT (~9-10 days of consumption)
- Major suppliers (2025): Russia (top), Iraq, Saudi Arabia, UAE
- India-Russia oil: Increased after Ukraine war (2022) — discounted Urals crude
Connection to this news: 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.
- Major maritime choke points: Strait of Hormuz, Strait of Malacca, Suez Canal, Bab-el-Mandeb, Strait of Gibraltar, Cape of Good Hope
- Bab-el-Mandeb: ~10% of global trade; disrupted by Houthi attacks 2023-2025
- Strait of Malacca: ~25% of global trade; critical for India's eastern trade routes
- UNCLOS: Governs rights of passage through international straits — transit passage rights (Article 38) apply to Hormuz
- Iran's legal argument: Claims the Strait is partly its territorial waters; UNCLOS counters with transit passage guarantee
Connection to this news: 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.
