What Happened
- US President Trump and Indian Prime Minister Modi held a phone conversation focused on the security situation in West Asia, including the safety of shipping through the Strait of Hormuz
- The leaders reviewed progress in India-US bilateral cooperation, with US Ambassador Sergio Gor indicating "incredible deals" in energy and other sectors were imminent
- The context is a fragile ceasefire between the US, Israel, and Iran following military operations; the Strait of Hormuz had faced disruptions affecting global energy supplies
- India has been diplomatically active — engaging both the US and Iran — given its heavy dependence on Gulf energy imports transiting Hormuz
- US Secretary of State Marco Rubio confirmed a visit to India in May 2026, indicating elevated diplomatic engagement

Strait of Hormuz — Strategic Geography and Energy Significance
The Strait of Hormuz is a narrow waterway (minimum width approximately 33 km) between Iran to the north and Oman and the UAE to the south, connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. It is the world's most important oil chokepoint: approximately 20–21 million barrels of oil per day transit the strait, representing roughly 20% of global petroleum liquids trade.
- The strait's navigable channel is only about 3.2 km wide in each direction, separated by a 3.2 km buffer zone
- Iran controls the northern shores; Oman controls parts of the southern approach
- Countries on the Persian Gulf side that depend on Hormuz for exports: Saudi Arabia, UAE, Kuwait, Iraq, Qatar, Bahrain, and Iran itself
- Approximately 90% of India's LPG imports transit the Strait of Hormuz
- India imports about 85% of its crude oil requirement; West Asia accounts for approximately 60% of Indian crude imports
Connection to this news: Any disruption to Hormuz transit directly threatens India's energy security — making the Modi-Trump conversation a direct expression of India's strategic stakes in West Asia stability.
UNCLOS and the Legal Regime of International Straits
The United Nations Convention on the Law of the Sea (UNCLOS), adopted in 1982 and in force since 1994, establishes the legal framework for navigation through international straits. The Strait of Hormuz qualifies as an "international strait" under UNCLOS because it connects two areas of the high seas/EEZ and is used for international navigation.
- UNCLOS Part III (Articles 37–44) governs transit passage through straits used for international navigation
- Transit passage (Article 38): Ships and aircraft have the right of continuous and expeditious transit; coastal states cannot suspend it; applies to Hormuz
- Innocent passage (Article 17): applies to territorial seas of coastal states; can be suspended for security reasons — a lower-grade right compared to transit passage
- Iran has not ratified UNCLOS but has signed it; Iran contests the transit passage regime, asserting ships must coordinate with the Iranian navy
- The transit passage regime is widely regarded as customary international law binding even on non-UNCLOS parties
- Article 44 of UNCLOS: "States bordering straits shall not hamper transit passage and shall give appropriate publicity to any danger to navigation"
Connection to this news: Any US or Iranian attempt to blockade or control the Strait raises direct UNCLOS legal questions — the US position is that transit passage cannot be legally impeded, while Iran disputes the applicability of UNCLOS to itself.
India's Energy Security Architecture
India's energy security policy is shaped by its overwhelming dependence on imported hydrocarbons and the strategic vulnerability this creates. The Ministry of Petroleum and Natural Gas and the Petroleum and Natural Gas Regulatory Board (PNGRB) are the key regulatory bodies; strategic petroleum reserves are maintained by Indian Strategic Petroleum Reserves Limited (ISPRL).
- India is the world's third-largest oil importer and consumer
- Strategic Petroleum Reserve capacity: approximately 5.33 million metric tonnes at Visakhapatnam, Mangalore, and Padur (covers approximately 9.5 days of consumption)
- India's LPG import dependence on Hormuz: ~90%
- Domestic LPG production: ~13 million tonnes/year; consumption: ~31 million tonnes/year (FY2024-25)
- Government response to Hormuz disruption (March 2026): increased kerosene allocation to states by 48,000 kl/quarter; permitted biomass and coal as alternative fuels; invoked Essential Commodities Act
Connection to this news: The Modi-Trump call reflects India's immediate concern about energy supply disruption, not just geopolitical stability — India needs Hormuz open as a practical matter of domestic energy supply.
India-US Strategic Partnership — Current Trajectory
The India-US Comprehensive Global Strategic Partnership, elevated progressively since the 2016 LEMOA agreement and the 2020 BECA agreement, has deepened across defence, trade, and technology. The two countries concluded an interim trade deal in February 2026, clearing a diplomatic irritant and paving the way for further cooperation.
- Key foundational defence agreements: LEMOA (Logistics Exchange Memorandum of Agreement, 2016), COMCASA (Communications Compatibility and Security Agreement, 2018), BECA (Basic Exchange and Cooperation Agreement, 2020)
- India-US bilateral trade: approximately $190 billion (FY2025)
- India-US interim trade deal (February 2026): reduced tariffs on select Indian goods, paving way for broader FTA negotiations
- Rubio's May 2026 India visit: first by a US Secretary of State in the current Trump administration; coincides with India hosting both Quad and BRICS FM meetings
Connection to this news: The Modi-Trump conversation on Hormuz reflects both countries' shared interest in energy market stability and signals the potential for an energy security component in upcoming India-US bilateral deals.
