Conflict at the Strait of Hormuz: Strategic Overview
The ongoing conflict in the Middle East, particularly around the Strait of Hormuz, has exposed the vulnerability of global trade routes concentrated through a handful of maritime choke points. The Strait of Hormuz, located between Oman and Iran, channels nearly 20% of the world's oil and liquefied natural gas (LNG) trade as of early 2025 (International Energy Agency, 2025). This narrow waterway, less than 60 kilometers wide at its narrowest point, is critical for energy exports from Gulf countries to global markets, including India, which imports approximately 80% of its crude oil through such routes (Ministry of Petroleum & Natural Gas, 2023). The conflict has underscored the fragility of global energy supply chains dependent on these constrained corridors.

Legal and Constitutional Framework Governing Maritime Choke Points
India’s jurisdiction over maritime zones is governed by the Maritime Zones of India Act, 1981, which defines the territorial sea, contiguous zone, and Exclusive Economic Zone (EEZ). International navigation rights through choke points like the Strait of Hormuz fall under the United Nations Convention on the Law of the Sea (UNCLOS), 1982, particularly Part III (Territorial Sea and Contiguous Zone) and Part V (Exclusive Economic Zone). UNCLOS guarantees the right of innocent passage and transit passage through international straits, balancing coastal state sovereignty with freedom of navigation. India’s Defence of India Act, 1962 empowers the Ministry of Defence and Ministry of External Affairs to safeguard maritime security, including through naval deployments in the Indian Ocean Region (IOR).
Economic Significance of Key Maritime Choke Points
The Strait of Hormuz and the Malacca Strait are among the world’s most critical maritime choke points. The Strait of Hormuz channels roughly 20% of global oil and LNG trade, while the Malacca Strait handles 15-20 million barrels per day of oil transit, making it the busiest oil transit corridor globally (Energy Information Administration, 2024). Disruptions in these corridors have immediate global economic consequences; for instance, the 2019 blockade in the Strait of Hormuz caused Brent crude prices to spike by 4% within days (Bloomberg, 2019). The global maritime trade volume passing through such choke points exceeds 50% of total seaborne trade (UNCTAD Review of Maritime Transport, 2023). India’s heavy reliance on these routes for energy imports exposes it to price volatility and supply disruptions.
Historical Precedents Demonstrating Choke Point Vulnerabilities
Choke points have historically shaped geopolitical outcomes. During World War I, the Dardanelles campaign was pivotal due to control over the Mediterranean-Black Sea link, influencing naval dominance and supply lines (Historical Military Records, 1915). In World War II, the Battle of the Atlantic centered on maintaining open sea routes vital for Allied logistics. These historical instances highlight how control and disruption of maritime chokepoints can determine conflict outcomes and economic stability.
Comparison of India and China’s Strategic Approaches
| Aspect | India | China |
|---|---|---|
| Dependence on Choke Points | High reliance on Strait of Hormuz and Malacca Strait for energy imports (80% crude oil imports) | Reduced dependence through diversified routes |
| Strategic Initiatives | Limited integrated maritime security framework; naval presence in IOR | ‘String of Pearls’ naval bases and China-Pakistan Economic Corridor (CPEC) for alternative overland and maritime routes |
| Energy Security | Vulnerable to disruptions at key choke points | Enhanced energy security via alternative corridors and investments in port infrastructure |
| Multilateral Cooperation | Emerging but fragmented regional maritime security cooperation | Active regional partnerships and infrastructure investments to secure trade routes |
Institutional Roles in Maritime Security and Trade
- International Maritime Organization (IMO): Sets international shipping safety and environmental standards in choke points.
- International Energy Agency (IEA): Monitors global energy flows and vulnerabilities.
- Indian Navy: Conducts maritime security operations ensuring freedom of navigation in the Indian Ocean Region.
- Ministry of External Affairs (MEA), India: Handles diplomatic engagements related to maritime security and energy diplomacy.
- United Nations Conference on Trade and Development (UNCTAD): Provides data on maritime trade volumes and trends.
- Energy Information Administration (EIA): Supplies data on global oil transit volumes and chokepoint traffic.
Critical Policy Gaps and Strategic Vulnerabilities
India lacks a comprehensive, integrated maritime security framework that combines diplomatic, military, and economic strategies to safeguard its energy supply chains passing through vulnerable choke points. Investment in alternative energy corridors and overland routes remains insufficient. Regional multilateral security cooperation is nascent and fragmented, limiting collective response capabilities to disruptions. The absence of diversified supply chains exacerbates exposure to geopolitical risks in the Middle East and Southeast Asia.
Way Forward: Enhancing Resilience of Global Choke Points
- Develop alternative energy transit routes, including overland pipelines and diversified maritime corridors.
- Strengthen India’s naval capabilities and presence in the Indian Ocean Region to ensure freedom of navigation.
- Enhance multilateral maritime security cooperation with regional partners, including ASEAN, Gulf countries, and the Quad.
- Leverage diplomatic channels to promote stability and conflict resolution in the Middle East.
- Invest in energy diversification to reduce dependence on fossil fuels transported through vulnerable choke points.
- The Strait of Hormuz is governed under the United Nations Convention on the Law of the Sea (UNCLOS) provisions on transit passage.
- It handles approximately 50% of global crude oil trade as of 2025.
- India imports nearly 80% of its crude oil through the Strait of Hormuz.
Which of the above statements is/are correct?
- China’s ‘String of Pearls’ strategy aims to reduce dependence on the Malacca Strait.
- India has fully developed alternative overland energy corridors similar to China’s CPEC.
- India’s maritime security framework integrates diplomatic, military, and economic strategies comprehensively.
Which of the above statements is/are correct?
Mains Question
“The concentration of global energy trade through maritime choke points like the Strait of Hormuz exposes critical vulnerabilities in India’s energy security. Analyse the strategic challenges posed by such choke points and suggest measures India should adopt to mitigate these risks.”
What is the legal regime governing navigation through international maritime choke points?
The United Nations Convention on the Law of the Sea (UNCLOS), 1982, particularly Part III and Part V, governs navigation rights through international straits and Exclusive Economic Zones. It guarantees the right of innocent and transit passage, balancing coastal state sovereignty with freedom of navigation.
Why is the Strait of Hormuz considered a critical maritime choke point?
The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman and the Arabian Sea, carrying about 20% of global oil and LNG trade (IEA, 2025). Its narrow width and geopolitical tensions make it highly vulnerable to disruptions affecting global energy markets.
How does India’s dependence on maritime choke points impact its energy security?
India imports nearly 80% of its crude oil, much of which transits through the Strait of Hormuz and Malacca Strait. Disruptions in these routes cause price volatility and supply uncertainty, exposing India to geopolitical risks beyond its control.
What strategic initiatives has China undertaken to reduce its vulnerability to choke points?
China’s ‘String of Pearls’ strategy and the China-Pakistan Economic Corridor (CPEC) develop alternative maritime bases and overland routes, reducing dependence on the Malacca Strait and enhancing energy security (South China Morning Post, 2023).
What are the key institutions involved in regulating and monitoring maritime choke points?
Key institutions include the International Maritime Organization (IMO) for shipping safety, the International Energy Agency (IEA) for energy flows, the Indian Navy for maritime security, and UNCTAD for trade data.
