The Strait of Hormuz, a narrow maritime chokepoint linking the Persian Gulf to the Gulf of Oman and Arabian Sea, remains under the de facto control of Iran. Approximately 21 million barrels per day (bpd) of crude oil—nearly 20% of the world's petroleum liquids trade—transit this strait (U.S. Energy Information Administration, 2023). Iran's strategic positioning allows it to influence global energy flows, creating persistent geopolitical tensions and economic uncertainties. Despite international calls for freedom of navigation, Iran's control complicates maritime security and trade stability, especially for energy-importing nations like India, which sources 60% of its crude oil through this route (Ministry of Petroleum and Natural Gas, India, 2023).

Legal Framework Governing Strait of Hormuz
The United Nations Convention on the Law of the Sea (UNCLOS) 1982 provides the primary legal framework for maritime zones and navigation rights. Under Part III (Territorial Sea and Contiguous Zone), coastal states exercise sovereignty up to 12 nautical miles, but Article 38 in Part III explicitly protects the right of transit passage through straits used for international navigation. The Strait of Hormuz, being an international strait, permits uninterrupted transit passage, limiting Iran's ability to impose unilateral restrictions legally.
However, enforcement mechanisms under UNCLOS are weak, and Iran’s control manifests through military presence and regulatory measures, complicating freedom of navigation. The International Maritime Organization (IMO) sets maritime security standards, but lacks enforcement power over sovereign states. India’s jurisdictional claims under the Indian Maritime Zones Act, 1976 do not extend to the Strait of Hormuz, underscoring the strait’s international status.
The United Nations Security Council (UNSC) has passed resolutions reaffirming freedom of navigation in the Persian Gulf region, but geopolitical rivalries hinder effective multilateral enforcement, leaving the strait vulnerable to coercive control.
Economic Significance and Risks Associated with Strait of Hormuz
The Strait of Hormuz is critical for global energy security. According to the U.S. Energy Information Administration (EIA), about 21 million bpd of crude oil pass through it, representing nearly 20% of global petroleum liquids trade. The International Energy Agency (IEA) estimates that disruptions in this chokepoint can spike crude oil prices by up to 20% within weeks, reflecting its systemic risk to energy markets.
- India imports over 80% of its crude oil by sea, with 60% routed via the Strait of Hormuz (MoPNG, 2023).
- Global shipping insurance premiums for vessels transiting the strait have surged 35% since 2019 due to heightened geopolitical risks (Lloyd’s Market Report, 2023).
- Approximately 30% of global liquefied natural gas (LNG) shipments also transit this chokepoint (IMO, 2023).
- Alternative infrastructure such as the UAE’s Habshan-Fujairah pipeline, with a capacity of 1.5 million bpd, aims to bypass the strait and reduce dependency (UAE Ministry of Energy, 2023).
Geopolitical Dynamics and Institutional Roles
Iran’s control over the Strait of Hormuz enables it to leverage regional influence and challenge global maritime norms. The IMO regulates maritime safety but cannot compel Iran to relinquish control. The UNSC faces diplomatic constraints in enforcing freedom of navigation due to veto powers and geopolitical alignments.
The International Energy Agency (IEA) monitors supply disruptions and advises member countries on strategic petroleum reserves and diversification. India’s Ministry of Petroleum and Natural Gas (MoPNG) actively pursues diversification of energy sources and routes to mitigate risks posed by the strait’s volatility.
Comparative Analysis: Strait of Hormuz vs. Strait of Malacca
| Aspect | Strait of Hormuz | Strait of Malacca |
|---|---|---|
| Geographical Control | De facto control by Iran, unilateral military presence | Multilateral control by Indonesia, Malaysia, Singapore |
| Security Framework | Limited enforcement, absence of binding multilateral security mechanism | Malacca Strait Patrols (MSP) since 2004, cooperative security reducing piracy by 50% |
| Trade Volume (Oil) | 21 million bpd (20% global petroleum liquids) | Approximately 15 million bpd |
| Maritime Risks | High geopolitical tension, increased insurance premiums (+35% since 2019) | Lower piracy incidents, stable shipping insurance rates |
Critical Legal and Security Gaps
UNCLOS provisions safeguard transit passage but lack enforceable mechanisms against unilateral coercion in strategic chokepoints like the Strait of Hormuz. The absence of a binding multilateral security framework leaves global trade vulnerable to geopolitical leverage by Iran. Current international law does not provide effective dispute resolution or enforcement tools to ensure uninterrupted navigation under contested control.
This legal lacuna contrasts with cooperative regional security models like the Malacca Strait Patrols, which have successfully mitigated risks through joint patrols and information sharing.
Way Forward: Enhancing Maritime Security and Energy Transit Resilience
- Establish a multilateral maritime security framework under IMO and UNSC auspices to guarantee freedom of navigation and rapid conflict de-escalation in the Strait of Hormuz.
- Accelerate development of alternative energy transit routes such as pipelines and LNG terminals to reduce dependency on the strait.
- India should expand strategic petroleum reserves and diversify suppliers to buffer against supply shocks.
- Strengthen diplomatic engagement with Gulf countries and Iran to promote adherence to UNCLOS transit passage rights.
- Enhance regional cooperation mechanisms involving littoral states to monitor and secure maritime traffic.
- The Strait of Hormuz falls entirely within Iran's territorial waters under UNCLOS.
- Article 38 of UNCLOS guarantees transit passage through international straits.
- The International Maritime Organization has enforcement powers to regulate military presence in the Strait of Hormuz.

- The UAE’s Habshan-Fujairah pipeline has a capacity of 1.5 million barrels per day.
- India currently imports 100% of its crude oil through alternative pipelines bypassing the Strait of Hormuz.
- Alternative routes reduce geopolitical risk but cannot fully replace maritime oil transit.

What is the legal status of the Strait of Hormuz under international law?
The Strait of Hormuz is classified as an international strait under UNCLOS, allowing uninterrupted transit passage for vessels of all states under Article 38. Coastal states like Iran can exercise sovereignty only within 12 nautical miles territorial sea but cannot impede transit passage.
How much of the world's oil supply passes through the Strait of Hormuz?
Approximately 21 million barrels per day, accounting for nearly 20% of global petroleum liquids trade, transit through the Strait of Hormuz (U.S. EIA, 2023).
What are the economic risks of disruptions in the Strait of Hormuz?
Disruptions can cause crude oil prices to surge by up to 20% within weeks, increase shipping insurance premiums by over 35%, and threaten energy security for import-dependent countries like India (IEA, Lloyd’s Market Report, MoPNG).
What alternative routes exist to bypass the Strait of Hormuz?
The UAE’s Habshan-Fujairah pipeline, with a capacity of 1.5 million bpd, is a key alternative. However, it cannot fully replace maritime oil transit, necessitating diversified energy strategies (UAE Ministry of Energy, 2023).
How does the security framework of the Strait of Hormuz compare with the Strait of Malacca?
The Strait of Malacca operates under a multilateral cooperative security framework (Malacca Strait Patrols), reducing piracy by 50%. In contrast, the Strait of Hormuz lacks such binding cooperation, increasing geopolitical risks (IMO, 2023).
