What Happened
- Iran's newly established Persian Gulf Strait Authority (PGSA) claimed control over waters south of the Strait of Hormuz, requiring all vessels transiting the waterway to obtain prior clearance from Iranian forces.
- Since late February 2026, shipping traffic through the strait has dropped to approximately 5% of pre-conflict levels following the outbreak of an armed conflict involving the US, Israel, and Iran.
- The IRGC (Islamic Revolutionary Guard Corps) has enforced the closure by boarding merchant ships, laying sea mines, and issuing warnings prohibiting passage to vessels bound for US, Israeli, or allied ports.
- Iran coordinated the transit of 26 vessels through the strait in 24 hours as a demonstration of its claimed authority, even as diplomatic negotiations over fully resuming traffic remained stalled.
- The strait's near-closure has caused global energy supply disruptions, with refined product shortages particularly acute in Asian markets.

Strait of Hormuz — Geography and Strategic Significance
The Strait of Hormuz is a narrow maritime passage connecting the Persian Gulf to the Gulf of Oman, and onward to the Arabian Sea and Indian Ocean. It lies between Iran (north coast) and Oman's Musandam Peninsula and the UAE (south coast). At its narrowest point it is approximately 33–39 km (21 nmi) wide, with inbound and outbound shipping lanes each 3 km (2 miles) wide, separated by a 3 km buffer zone. It is classified as one of the world's foremost maritime choke points — a strategic bottleneck through which no alternative maritime route exists from the Persian Gulf to the open ocean.
- Location: between Iran (north) and Oman/UAE (south); approximately 167 km long.
- Narrowest navigable width: approximately 33 km; shipping lanes are 3 km each.
- Average daily oil flow (pre-2026): approximately 20 million barrels per day — roughly 20% of global oil consumption.
- Approximately 84% of Hormuz crude oil flows to Asian markets; China, India, Japan, and South Korea combined account for 69% of Hormuz crude flows.
- India's dependence: approximately 40% of crude oil imports transit through Hormuz; also 80–85% of LPG and 60% of LNG imports.
Connection to this news: Iran's establishment of a transit authority over the strait directly threatens global energy supply chains and India's energy security, making the crisis a major geopolitical test.
UNCLOS and the Legal Status of International Straits
The United Nations Convention on the Law of the Sea (UNCLOS), adopted in 1982 and entering into force in 1994, governs transit through international straits under Part III (Articles 34–45). Under Article 38, vessels enjoy the right of "transit passage" through straits used for international navigation — a right that cannot be suspended even in war, unlike "innocent passage" through territorial seas. The Strait of Hormuz qualifies as such an international strait because both its outer limits lie within the territorial waters of Iran and Oman (each having declared 12-nautical-mile territorial seas in the 1970s), but it constitutes the only sea route from the Persian Gulf to the open ocean.
- UNCLOS adopted: 10 December 1982; entered into force: 16 November 1994.
- "Transit passage" (Art. 38) cannot be suspended; "innocent passage" (Art. 19) can be suspended in territorial seas.
- Iran is not a party to UNCLOS (has not ratified); it argues customary international law allows it to control transit.
- Oman expanded its territorial sea to 12 nautical miles in 1972; Iran did so in 1959 — meaning the strait lies entirely within their combined territorial waters.
- The shipping lanes lie mostly in Omani territorial waters but have historically operated under the transit passage regime.
- India ratified UNCLOS in 1995.
Connection to this news: Iran's Persian Gulf Strait Authority and the requirement of prior clearance directly contravenes the transit passage regime under UNCLOS, representing one of the most significant challenges to international maritime law in recent decades.
Iran–Israel and US Conflict — India's Strategic Interests
India's "Act West" orientation, energy dependence on the Persian Gulf, and large diaspora in the Gulf Cooperation Council (GCC) states make the Iran–Israel–US conflict directly consequential for Indian interests. India imports crude oil from over 40 countries, but approximately 40% still passes through Hormuz. India has historically maintained strategic autonomy — maintaining diplomatic relations with both Iran (including the Chabahar port investment on Iran's coast) and Israel (a major defense partner), and has avoided taking sides in the conflict.
- India's crude oil import dependency: 80–85% of domestic consumption is imported.
- Share transiting Hormuz: approximately 40% of crude, 80–85% of LPG, 60% of LNG.
- Chabahar Port (Iran, Sistan-Baluchestan Province): India's strategic investment on the Gulf of Oman — a route that bypasses Pakistan and connects to Afghanistan and Central Asia.
- India–Iran relationship: governed by the 2003 New Delhi Declaration and subsequent bilateral agreements; Iran is also linked to INSTC (International North–South Transport Corridor).
- GCC diaspora: approximately 9 million Indians live in Gulf states, representing the largest Indian diaspora cluster.
Connection to this news: Iran's claim of control over Hormuz waters directly threatens India's energy supply lines, remittance flows, and diaspora welfare, making this a high-stakes geopolitical development for New Delhi.
Maritime Choke Points — UPSC Geography Concept
Maritime choke points are narrow strategic waterways through which a large proportion of global trade and energy flows pass, making them critical to energy security and global supply chains. The world's major oil transit choke points include: Strait of Hormuz (Persian Gulf → Arabian Sea), Strait of Malacca (Indian Ocean → South China Sea/Pacific), Bab-el-Mandeb (Red Sea → Gulf of Aden), Suez Canal (Mediterranean → Red Sea), and Cape of Good Hope (alternative route bypassing the above).
- Strait of Malacca: ~3.5 km at narrowest; handles ~25% of global traded goods and 80% of China's oil imports.
- Bab-el-Mandeb: connects Red Sea to Gulf of Aden; 30 km wide; Houthi attacks disrupted traffic in 2023–25.
- Suez Canal: handles ~12% of global trade; blocked by MV Ever Given in March 2021 for 6 days.
- Strait of Hormuz: ~20% of global oil supply; no alternative route from the Persian Gulf to the open ocean.
Connection to this news: The 2026 Hormuz crisis exemplifies the strategic vulnerability of choke-point-dependent global energy systems and the leverage such geography confers on Iran.
