Maritime Chokepoints and India's Energy Security: Strait of Hormuz, Malacca & Beyond
How the Strait of Hormuz, Malacca, and Bab-el-Mandeb shape India's energy security — geopolitics, import dependence, and India's strategic response.
Map of maritime chokepoints affecting India’s energy routes, including Hormuz and Malacca.
When the Sea Holds Your Economy Hostage
In early 2026, escalating conflict in West Asia forced India to invoke the Natural Gas Control Order under the Essential Commodities Act — a rarely used emergency provision. The Indian crude oil basket, stable through much of FY2025-26, spiked to over $113 per barrel. Refineries scrambled for alternative cargoes. The episode was a stark reminder of a structural truth India has long acknowledged but insufficiently addressed: nearly 30% of India's crude imports pass through a single strait it does not control — the Strait of Hormuz. Disrupt it, and the entire economy feels the tremor.
This is not a hypothetical vulnerability. It is an everyday geopolitical reality.
Understanding Maritime Chokepoints
Maritime chokepoints are narrow sea passages where the bulk of global energy trade is funnelled — and where disruption can cascade into economic crisis within days. Three are critical to India's strategic calculus.
The Strait of Hormuz, a 33-km passage between Iran and Oman-UAE, is the Persian Gulf's only outlet to the open ocean. Roughly 20 million barrels of crude oil — about 20% of global supply — transit it daily. Any Iran-Gulf standoff, US-Iran military flashpoint, or asymmetric mining of the strait can disrupt supplies to India, China, Japan, and South Korea simultaneously. It is, in effect, the world's most critical energy corridor.
The Strait of Malacca is arguably even more consequential in volume terms. This 900-km corridor — just 2.8 km wide at its narrowest — links the Indian Ocean to the South China Sea and the Pacific. It handles approximately 23.2 million barrels per day, representing 29% of global maritime oil flows, surpassing even Hormuz. Nearly 80,000 ships transit it annually, carrying around $3.5 trillion in trade. India's Andaman and Nicobar Islands sit at its western entrance, giving India natural geographic proximity and strategic leverage.
The Bab-el-Mandeb (Arabic: "Gate of Tears"), between Yemen and Djibouti, is India's corridor to Europe via the Red Sea and Suez Canal. Its vulnerability was demonstrated vividly in 2023-24, when Houthi militant attacks on commercial shipping caused over 60% of Suez Canal traffic to reroute around the Cape of Good Hope — adding up to 2 weeks extra per voyage, tripling freight rates, and raising costs for Indian exporters. Beyond these three, the Lombok and Sunda Straits of Indonesia serve as vital bypass routes when Malacca is congested or unsafe, and the Suez Canal itself remains a critical artery for India's trade with Europe and the Americas.
India's Energy Import Dependency: The Numbers
India is the world's third-largest consumer of petroleum and also its fourth-largest LNG importer. The dependency is structural and deepening. Today, ~89% of India's crude oil is imported. For natural gas, imports now account for over 51% of total availability — having crossed domestic production for the first time in 2024-25. Coal imports, despite record domestic production crossing 1 billion tonnes, still stand at over 263 million tonnes annually, largely for coking coal needs of the steel sector.
Where India sources its energy:
- Crude Oil - Iraq, Saudi Arabia, Russia, UAE, Kuwait, USA
- LNG - Qatar, UAE, Australia, USA
- Coal - Indonesia, Australia, South Africa, Russia, USA
- LPG - Saudi Arabia, UAE, Kuwait
Nearly 40% of India’s crude imports and over 50% of LNG imports pass through the Strait of Hormuz. The arithmetic of India's vulnerability is not abstract — it is priced into every fuel bill.
Geopolitical Dimensions
India's geographic advantage is real. Its 7,516-km coastline spans both the Arabian Sea and Bay of Bengal. The Andaman and Nicobar Islands sit at the Malacca entrance. This positioning allows India to act as a net security provider — not just a passive transit-dependent state.
China's Malacca Dilemma defines the strategic competition. Between 75–80% of China's energy imports transit the Strait of Malacca. India's geographic position at Malacca's entrance offers it considerable leverage — a fact that drives China's alternative infrastructure bets across the region.
China's String of Pearls — a network of commercial ports, logistics hubs, and naval facilities across the IOR — is the dominant counter-strategy. These installations allow China to monitor sea lanes, project naval power, and potentially encircle India's maritime approaches. India has responded not by matching ports with ports, but through strategic doctrine and regional coalitions: the SAGAR Doctrine (Security And Growth for All in the Region) frames India as a responsible net security provider. Institutions like IONS (Indian Ocean Naval Symposium), IFC-IOR (Information Fusion Centre – Indian Ocean Region) in Gurugram, and the Quad (India, US, Japan, Australia) anchor India's maritime security posture. India's Mission-Based Naval Deployments (MBDs) now maintain round-the-clock presence across key chokepoints.
Freedom of Navigation is India's standing policy position under UNCLOS principles. India consistently advocates for open, rules-based sea lanes — a position that aligns with both its own economic interests and those of the broader Indo-Pacific community.
Organisations & Frameworks
The international architecture governing maritime trade and chokepoint security involves both legal frameworks and operational bodies that India must actively leverage.
The International Maritime Organisation (IMO) sets global standards for shipping safety, environmental regulation, and security protocols — making it the foundational regulatory body for any chokepoint governance discussion. UNCLOS (UN Convention on the Law of the Sea), ratified by India in 1995, provides the legal basis for freedom of navigation, Exclusive Economic Zones, and territorial sea rights. It is the cornerstone of the rules-based maritime order India champions.
ReCAAP (Regional Cooperation Agreement on Combating Piracy and Armed Robbery Against Ships in Asia) is the multilateral mechanism specifically designed for Malacca Strait security. It brings together 21 member states to share intelligence and coordinate anti-piracy operations — directly relevant to keeping the world's busiest lane open.
On the connectivity side, I2U2 (India, Israel, UAE, USA) and the India-Middle East-Europe Economic Corridor (IMEC), launched at the G20 New Delhi Summit in 2023, represent India's effort to build alternative energy and trade routes that reduce chokepoint dependence. IMEC envisions a rail-and-port corridor linking India to Gulf states and Europe — a structural hedge against Hormuz and Bab-el-Mandeb disruptions.
Regional Impact & India's Leadership Opportunity
Chokepoint disruptions are never contained. The 2023-24 Houthi crisis cascaded from the Red Sea to Amazon delivery timelines in the US, auto-parts shortages in Germany, and higher food prices across South Asia. Insurance premiums on vessels operating in conflict-proximate waters multiply freight costs even when physical flows remain intact. For India, higher import bills translate directly to inflation, current account pressure, and slower industrial growth.
Southeast Asian nations — Indonesia, Malaysia, Singapore — are central to Malacca's stability and are natural partners for India. Nearly 40% of India's trade involves littoral nations along the Indian Ocean Rim, making collective resilience a shared economic interest, not just a strategic preference.
This is where India's regional architecture offers an underutilised advantage. India should leverage existing institutions — IORA (Indian Ocean Rim Association, 23 member states), BIMSTEC (Bay of Bengal Initiative), the Colombo Security Conclave, and IONS — to coordinate among Rim countries, build shared maritime domain awareness, and establish common protocols for supply continuity during disruptions. Rather than reacting bilaterally to each crisis, India has the standing, geography, and diplomatic capital to lead a collective chokepoint-resilience framework across the IOR. At the global level, India must use forums like the G20, IMO, and UNCLOS review processes to raise its concerns, push for codified freedom-of-navigation guarantees, and advocate for chokepoint security as a matter of global commons governance — not just bilateral interest.
Progress Made So Far
India has not been passive. On the energy security front, the Strategic Petroleum Reserve (SPR) — managed by Indian Strategic Petroleum Reserves Limited (ISPRL) — maintains underground caverns at Visakhapatnam (Andhra Pradesh), Mangaluru, and Padur (both in Karnataka), with a combined Phase-I capacity of 5.33 MMT (million metric tonnes), equivalent to roughly 9.5 days of crude supply. Including commercial stocks held by oil marketing companies, India's total national crude and petroleum storage currently covers approximately 74 days — still well short of the 90-day International Energy Agency (IEA) benchmark. Phase-II expansion at Chandikhol (Odisha) and an additional Padur cavern has been approved, with construction at Padur awarded in October 2025.
On supply diversification, India's imports from Russia surged dramatically after 2022 — touching €5.3 billion by March 2026 — reducing Gulf concentration risk even as it created new geopolitical questions. Chabahar Port in Iran and the International North-South Transport Corridor (INSTC) offer overland and sea-rail alternatives that bypass both Pakistan and Hormuz to reach Central Asia. The Great Nicobar transhipment hub, currently under development, will strengthen India's physical presence at the Malacca entrance.
The Road Ahead: Diversification, Resilience, and Strategy
Diversification must go further than bilateral supplier deals. Corridors like IMEC (India-Middle East-Europe Economic Corridor) and the I2U2 framework extend India's approach westward — building redundant trade and energy routes linking India to Gulf states and Europe so that no single chokepoint holds a veto over supply continuity.
Resilience depends on domestic capacity. Pipelines such as Urja Ganga, Jagdishpur–Haldia Phase II, and Mundra–Panipat strengthen inland distribution, limiting the impact of coastal supply shocks. LNG regasification is set to rise from 2.1 Trillion Cubic Feet (TCF) to ~4.0 TCF, supporting a shift to 15% gas in the energy mix by 2030. Completing SPR Phase-II will move India closer to the 90-day storage benchmark, while renewables — growing from 198 GW in 2024 to a target of 500 GW by 2030 — reduce long-term fossil fuel import dependence.
Strategy aligns both. India must accelerate Great Nicobar as a forward logistics and surveillance hub near Malacca; expand its submarine fleet — including nuclear-powered assets — for persistent undersea deterrence; and scale aircraft carrier capability beyond INS Vikrant for sustained blue-water presence. Simultaneously, strengthening IORA and BIMSTEC for operational coordination, and leveraging global platforms like the G20 and UNCLOS, will help secure freedom of navigation and frame chokepoint stability as a global commons priority.
Conclusion: Geography Is Not Destiny — But It Demands Strategy
The Strait of Hormuz, Bab-el-Mandeb, and Malacca are not distant geography. They are embedded in the price of every litre of petrol, every power tariff, and every manufactured good in India. The 2026 West Asia crisis was a live rehearsal of consequences India cannot afford to ignore.
India's aspiration to be a net security provider in the Indian Ocean is not altruism — it is strategic self-interest backed by geographic advantage, a growing blue-water navy, and an expanding web of regional institutions. Converting that aspiration into durable energy security requires simultaneously securing the sea lanes, building domestic resilience, and leading the multilateral architecture that governs the global maritime commons.
