What Happened
- The ongoing Iran-related conflict has resulted in a near-total disruption of commercial shipping through the Strait of Hormuz, with Iran having effectively closed the waterway to significant traffic following the escalation of military operations beginning in late February 2026.
- A US naval blockade, formally implemented from 13 April 2026, has compounded the closure: the US Navy is clearing mines and preventing commercial vessels without clearance from transiting the strait; Iran has accused the US of violating ceasefire terms following an incident in which a US destroyer fired on an Iranian-flagged cargo ship.
- Iran has indicated it is not prepared to attend a new round of diplomatic talks in Pakistan as of 20 April 2026, raising uncertainty about the prospects for a negotiated reopening of the waterway.
- India is among the most exposed nations: approximately 50% of India's crude oil imports and most of its LPG supplies transit the Strait of Hormuz; additionally, a US waiver on Russian crude purchases expired on 11 April, removing a key alternative supply source simultaneously.
- Two Indian-flagged vessels have been targeted or turned back in the strait, and Indian energy companies including Petronet LNG have reported significant supply chain disruptions.

The Strait of Hormuz — Strategic Geography
The Strait of Hormuz is a narrow waterway approximately 33–39 km wide at its narrowest point, connecting the Persian Gulf with the Gulf of Oman and the Arabian Sea. It is the world's most strategically significant maritime chokepoint: approximately 20–21 million barrels per day (about 20% of global oil supply) transit it in normal conditions, along with substantial volumes of LNG, petrochemicals, and fertiliser inputs.
- Location: between Iran (to the north) and Oman/UAE (to the south)
- Width at narrowest: approximately 33 km; navigable channel is two lanes of 3 km each, separated by a 3 km median
- Countries whose exports primarily route through Hormuz: Saudi Arabia, UAE, Kuwait, Iraq, Qatar, Bahrain, and Iran
- Global oil share: approximately 20% of global petroleum trade
- Global LNG share: approximately 25–30% (Qatar is the world's second-largest LNG exporter)
- Also critical for: fertilisers, petrochemicals, container shipping to South and Southeast Asia
Connection to this news: Iran's strategic location on the northern shore gives it de facto ability to threaten or interrupt transit through the strait — a capability it has periodically invoked as a deterrent. The 2026 closure is the most severe materialisation of this threat in history, triggering a global energy and commodity price shock.
UNCLOS and Freedom of Navigation Through International Straits
The United Nations Convention on the Law of the Sea (UNCLOS, 1982) governs the legal regime for international straits. Part III of UNCLOS (Articles 34–45) establishes the right of "transit passage" through straits used for international navigation.
- Article 38(1) of UNCLOS: All ships and aircraft enjoy the right of transit passage in straits used for international navigation between one part of the high seas or EEZ and another
- Transit passage: continuous and expeditious navigation; applies to commercial vessels, warships, and submarines (which may transit submerged)
- Coastal state obligations: may not suspend or hamper transit passage; may designate sea lanes and prescribe traffic separation schemes
- Coastal state rights: limited to regulating safety, pollution prevention, and customs — cannot require prior permission or notification for transit
- Iran is not a signatory to UNCLOS, but the transit passage regime is widely considered customary international law
- India signed and ratified UNCLOS; it is a foundational element of India's maritime security doctrine and "SAGAR" (Security and Growth for All in the Region) policy
Connection to this news: Iran's effective closure of the Strait of Hormuz constitutes a violation of the transit passage regime under customary international law. The US military's stated justification for blockade operations partly invokes freedom of navigation principles — the same framework India applies in the South China Sea context — creating a complex legal and diplomatic situation for India.
India's Oil Import Dependency and the Gulf
India is the world's third-largest crude oil importer, consuming approximately 5 million barrels per day. The Gulf region (Iraq, Saudi Arabia, UAE, Kuwait, Qatar, Oman) historically supplied 60–70% of India's crude oil, though diversification toward Russia raised non-Gulf shares significantly after 2022.
- Gulf share of India's crude imports: reduced from ~72% in 2017–18 to approximately 46–50% by early 2026, partially offset by Russian crude rising to ~35–36% of total imports (FY 2024–25)
- Hormuz-transiting volumes: approximately 2.6 million barrels per day from Gulf sources in January–February 2026, accounting for ~50% of total Indian crude imports
- LPG: India is the world's second-largest LPG consumer; most household LPG (cooking gas) comes from Gulf sources routed through Hormuz
- Russian oil waiver: a US waiver allowing countries to purchase Russian crude expired on 11 April 2026, removing this source simultaneously with the Hormuz blockade
- Indian-flagged vessels targeted: at least two ships, including the VLCC Sanmar Herald, were fired upon or turned back at the strait in April 2026
- Petronet LNG: reported inability to safely route LNG carriers to Ras Laffan (Qatar), cutting domestic gas supply for urea production and power generation
Connection to this news: India faces a simultaneous squeeze on two of its three major oil/gas supply sources (Gulf and Russia), with no short-term alternative at the required scale. The crisis underscores the strategic vulnerability inherent in import dependency and the importance of emergency stockpiling, alternative routing (via Cape of Good Hope), and energy demand management.
Iran's Nuclear Programme — Background
Iran's nuclear programme has been a central point of international concern since the early 2000s. The Joint Comprehensive Plan of Action (JCPOA), signed on 14 July 2015 between Iran and the P5+1 (USA, UK, France, Russia, China, and Germany), placed verifiable limits on Iran's uranium enrichment, plutonium reprocessing, and centrifuge numbers in exchange for sanctions relief. The IAEA verified Iran's compliance, and the deal was implemented on 16 January 2016.
- JCPOA signed: 14 July 2015; implemented: 16 January 2016
- Key limits: uranium enrichment capped at 3.67%; enriched uranium stockpile capped at 300 kg; Arak heavy water reactor redesigned; IAEA additional protocol inspections
- US withdrawal: announced 8 May 2018 under President Trump (first term); maximum pressure sanctions reimposed
- Post-withdrawal: Iran progressively resumed enrichment; by 2023–24, enrichment reached up to 60% (weapons-grade threshold is ~90%)
- 2026 context: Iran's nuclear programme and its military dimensions became a direct trigger for the current conflict; nuclear status remains one of three main issues in Pakistan-mediated talks (alongside Hormuz control and war reparations)
Connection to this news: The current conflict is in significant part a consequence of the failure to maintain or revive the JCPOA framework. The 2026 crisis represents the most severe outcome of the decade-long proliferation-vs-diplomacy tension over Iran's nuclear ambitions, directly impacting India's energy security and regional stability.
