What Happened
- At least 10 foreign-flagged tankers loaded with crude oil and LPG destined for India remain stranded in the Persian Gulf as of March 30, 2026, unable to safely transit the Strait of Hormuz amid the US-Iran war.
- A broader group of approximately 22 vessels carrying crude, LPG, and liquefied natural gas had been anchored in the strait or western Persian Gulf, with transits only proceeding cautiously and intermittently.
- Two Indian-flagged LPG carriers — BW TYR and BW ELM — carrying a combined 94,000 tonnes of LPG (roughly a day's cooking gas supply for India) successfully transited the Strait earlier this week under Indian naval escort as part of Operation Sankalp.
- Between March 14-24, five Indian-flagged LPG carriers were evacuated from the Strait in three separate operations, escorted by Indian Navy warships through the Gulf of Oman.
- India's Petroleum Ministry has stated that approximately 70% of crude imports are now being rerouted through non-Hormuz channels, reflecting a diversification effort, but LPG remains the critical vulnerability: India imports 60% of its LPG consumption, of which about 90% comes through the Strait of Hormuz.
- The stranding is contributing to fuel supply concerns and price pressures, with the government monitoring the situation closely and coordinating with oil marketing companies (OMCs) on buffer stocks.

The Strait of Hormuz — The World's Most Critical Oil Chokepoint
The Strait of Hormuz is a narrow waterway approximately 33 kilometres wide at its narrowest point, connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. It lies between Iran to the north and Oman and the UAE to the south. Approximately 20 million barrels of crude oil and petroleum products per day — roughly 20% of global oil supply — pass through the strait, making any disruption of passage a global energy emergency.
- The strait operates through designated shipping lanes: a 3.2 km inbound and 3.2 km outbound lane, with a 3.2 km separation zone.
- About 40% of India's crude oil imports and 90% of its LPG imports transit the strait — among the world's highest dependency rates for any single economy.
- China, Japan, South Korea, and India are the four largest importers of crude through the Strait of Hormuz in Asia, collectively accounting for 69% of all Hormuz crude flows.
- The 1958 and 1982 UN Conventions on the Law of the Sea (UNCLOS) guarantee "transit passage" rights through international straits — but enforcement depends on practical naval control.
- Iran has previously threatened to close the strait during periods of tension with the US (2011-12, 2018-19); this is the first time active US military operations against Iran have directly disrupted transit.
Connection to this news: India's energy security is directly at risk from a Hormuz disruption. The stranding of tankers bound for India illustrates how India's import dependency on a geopolitically contested chokepoint translates immediately into domestic energy supply risk.
India's Energy Security — Structural Vulnerabilities and Policy Responses
India imports approximately 85-88% of its crude oil needs, spending over $130 billion annually on energy imports. This structural dependence makes India uniquely vulnerable to geopolitical shocks in West Asia. The government's energy security strategy includes diversification of supply sources, strategic petroleum reserves, and naval operations to protect sea lanes.
- India's Strategic Petroleum Reserve (SPR): three underground rock cavern facilities at Visakhapatnam (1.33 MMT), Mangaluru (1.5 MMT), and Padur (2.5 MMT) — totalling 5.33 million metric tonnes, roughly 9-10 days of net imports.
- Operation Urja Suraksha (Energy Security): India's ongoing effort to coordinate naval protection of energy-supply sea lanes amid the West Asia conflict.
- Operation Sankalp: The Indian Navy's escort operation for Indian-flagged tankers through the Strait of Hormuz, active since March 2026.
- India has diversified crude sources since 2022 — purchases from Russia now account for over 30% of imports, reducing Gulf dependency but not eliminating Hormuz exposure for LPG.
- The Petroleum and Natural Gas Ministry's emergency protocols include coordinating with HPCL, BPCL, and IOC on LPG buffer stocks and rationalising distribution.
Connection to this news: India's SPR and diversification efforts cushion but do not eliminate Hormuz risk — particularly for LPG, where no non-Gulf alternative exists at scale. The stranded tankers test the adequacy of India's energy security buffers in real time.
India-Iran Relations and Diplomatic Considerations
India and Iran have historically maintained warm bilateral ties rooted in civilisational links, trade, and India's access to Afghanistan and Central Asia via the Chabahar Port route. India is legally bound by UN-sanctioned international law but not by unilateral US sanctions on Iran. However, secondary sanction threats from the US have constrained India's economic engagement with Iran since 2018.
- Chabahar Port: India has invested in developing the Iranian port as a transit route to Afghanistan and Central Asia; it was partially exempted from US sanctions in 2018.
- India abstained on UN resolutions related to the Iran nuclear standoff in 2022-23, reflecting its strategic autonomy posture.
- India's oil imports from Iran peaked at approximately 10-12% of total imports before US sanctions reduced them to near zero in 2019-20.
- During the current conflict, India has engaged in back-channel diplomacy to ensure safe passage for civilian vessels while avoiding direct involvement in US military operations.
- India's position: not party to the US-Iran conflict, seeking neutral passage rights under UNCLOS.
Connection to this news: India's ability to secure safe passage for its tankers — through Operation Sankalp and diplomatic engagement — relies on Iran accepting that Indian vessels are civilian/neutral. This is a delicate balance, given India's close US ties and the operational environment near Iranian waters.
LPG Supply Chain — India's Specific Vulnerability
Liquefied Petroleum Gas (LPG) is the primary cooking fuel for over 320 million households in India, distributed via the Pradhan Mantri Ujjwala Yojana (PMUY) network and the broader DBTL (Direct Benefit Transfer for LPG) scheme. India imports 60% of its LPG needs, primarily from Qatar, Saudi Arabia, UAE, and Kuwait — all accessed via the Strait of Hormuz. Unlike crude oil, LPG has fewer alternative supply routes and requires specialised Very Large Gas Carriers (VLGCs) for transport.
- India's LPG consumption: approximately 27-28 million metric tonnes per year, making it the world's second-largest LPG importer.
- PMUY beneficiaries: over 103 million households — predominantly rural and economically weaker sections — depend on subsidised LPG cylinders.
- India's buffer stock for LPG is much thinner than for crude oil — estimated at 10-15 days under normal consumption.
- VLGC freight rates have surged since the Hormuz disruption, adding to India's import bill even for vessels that successfully transit.
- Indian state oil companies (HPCL, BPCL, IOC) are the primary LPG importers and distributors.
Connection to this news: The 10+ stranded tankers are predominantly LPG carriers — precisely India's most vulnerable import category. Any sustained disruption to LPG supply would directly affect domestic cylinder availability, particularly for PMUY beneficiaries, with political and social consequences.
