Introduction: Strategic Importance of the Strait of Hormuz
The Strait of Hormuz is a narrow maritime chokepoint located between Oman and Iran, linking the Persian Gulf with the Gulf of Oman and the Arabian Sea. It is approximately 21 nautical miles wide at its narrowest point, with Iran controlling about 21 nautical miles of territorial waters on its northern coast under UNCLOS 1982 provisions. As of 2023, nearly 21 million barrels per day (mbpd) of oil, representing 20% of global petroleum liquids, transit through this strait (U.S. Energy Information Administration, 2023). Iran’s continued control over this critical passage presents significant geopolitical and economic risks to global energy security and maritime trade, especially for energy-importing countries like India.

Legal Framework Governing the Strait of Hormuz
The legal status of the Strait of Hormuz is governed primarily by the United Nations Convention on the Law of the Sea (UNCLOS) 1982. Under Part II, coastal states have sovereignty over territorial seas extending up to 12 nautical miles from their baselines. Iran exercises sovereignty over its territorial waters in the strait, but under Part III of UNCLOS, ships of all states enjoy the right of transit passage through international straits used for international navigation, which cannot be impeded.
- Part II (Territorial Sea and Contiguous Zone): Defines sovereignty and rights of coastal states.
- Part V (Exclusive Economic Zone): Relevant for resource rights but less critical for navigation.
- Part VII (High Seas): Governs freedom of navigation beyond territorial seas.
- IMO regulations mandate navigation safety and pollution prevention in the strait.
- Relevant UN Security Council Resolutions uphold freedom of navigation and call for de-escalation of tensions in the region.
- India’s Merchant Shipping Act, 1958 (amended 2017) governs Indian shipping interests, emphasizing maritime security and compliance with international law.
Economic Impact of Iran’s Control on Global and Indian Energy Security
The Strait of Hormuz is a vital artery for global energy supplies. According to the U.S. Energy Information Administration (2023), approximately 21 mbpd of crude oil and petroleum products pass through this strait, accounting for one-fifth of global petroleum liquids. Any disruption caused by geopolitical tensions or unilateral Iranian actions could spike crude oil prices by 20-30%, exacerbating inflationary pressures worldwide.
- India’s crude oil import bill was $144 billion in 2023 (Ministry of Commerce & Industry, India).
- About 60% of India’s crude oil imports transit via the Strait of Hormuz (Indian Ministry of Petroleum, 2023), exposing India to supply shocks.
- Insurance premiums for tankers in the Strait region surged by 40% since 2022 (Lloyd’s List Intelligence), increasing operational costs for shipping companies.
- Price volatility in crude oil markets directly affects India’s fiscal deficit and inflation.
Institutional Roles and Stakeholder Perspectives
Several international and national institutions shape the governance and security environment of the Strait of Hormuz:
- International Maritime Organization (IMO): Sets navigation safety and environmental standards to ensure secure and efficient maritime trade.
- United Nations Security Council (UNSC): Addresses threats to international peace, including freedom of navigation in strategic straits.
- Indian Ministry of External Affairs (MEA): Formulates diplomatic policy balancing India’s energy security and regional stability.
- Indian Ministry of Petroleum and Natural Gas: Oversees diversification of energy sources and risk mitigation related to supply disruptions.
- International Energy Agency (IEA): Monitors global energy supply risks and advises on strategic petroleum reserves.
- Lloyd’s List Intelligence: Provides maritime risk assessments and insurance data critical for shipping companies.
Comparative Analysis: Strait of Hormuz vs. Malacca Strait
The Malacca Strait, controlled by Indonesia, Malaysia, and Singapore, is another key maritime chokepoint through which approximately 25% of global traded goods pass. Unlike the Strait of Hormuz, the Malacca Strait benefits from a robust multilateral security framework involving joint patrols and information sharing, which has reduced piracy and ensured uninterrupted trade.
| Aspect | Strait of Hormuz | Malacca Strait |
|---|---|---|
| Geographical Control | Unilateral control by Iran over territorial waters | Shared control by Indonesia, Malaysia, Singapore |
| Legal Status | International strait under UNCLOS with Iran’s territorial claims | International strait under UNCLOS with cooperative sovereignty |
| Security Mechanism | Lack of multilateral security framework, high geopolitical tensions | Multilateral joint patrols and cooperative maritime security |
| Economic Impact | 21 mbpd oil transit, vulnerable to disruption and price shocks | Major trade route for goods, reduced piracy risks via cooperation |
| Insurance Costs | 40% increase in tanker insurance premiums since 2022 | Relatively stable insurance premiums due to security cooperation |
Critical Gaps and Challenges
The absence of a robust multilateral security mechanism for the Strait of Hormuz leaves global shipping vulnerable to unilateral disruptions by Iran, escalating geopolitical tensions. The current legal framework under UNCLOS guarantees transit passage but lacks enforcement mechanisms to prevent coercive actions. This gap complicates India’s strategic calculus, given its heavy dependence on oil imports through this route.
- Iran’s sovereignty claims conflict with the principle of freedom of navigation.
- Geopolitical rivalries, including U.S.-Iran tensions, exacerbate risks of conflict.
- Absence of coordinated international naval presence limits deterrence against disruptions.
- Insurance and operational costs for shippers remain elevated, affecting global supply chains.
Way Forward: Strategic and Legal Responses
- Promote a multilateral maritime security framework involving Gulf littoral states, India, and global powers to ensure freedom of navigation while respecting Iran’s sovereignty.
- Strengthen implementation and enforcement of UNCLOS provisions, particularly transit passage rights, through diplomatic and legal channels.
- India should diversify its energy import routes and sources, including enhancing strategic petroleum reserves and exploring alternative corridors such as the Chabahar port.
- Enhance cooperation with IMO and IEA to monitor risks and coordinate crisis response mechanisms.
- Leverage diplomatic engagement via the UNSC to de-escalate tensions and uphold international maritime law.
- The Strait of Hormuz is governed exclusively by Iran’s national maritime laws.
- UNCLOS guarantees the right of transit passage through international straits like Hormuz.
- India imports over half of its crude oil through the Strait of Hormuz.
Which of the above statements is/are correct?
- The Malacca Strait is controlled unilaterally by Indonesia.
- The Strait of Hormuz lacks a robust multilateral security mechanism.
- Both straits have seen a similar increase in tanker insurance premiums since 2022.
