What Happened
- The United States expanded the theatre of its military campaign against Iran into the Indian Ocean, marking a significant escalation of the Israel-Iran conflict that began in early 2026.
- A U.S. submarine attacked an Iranian ship in waters proximate to India's strategic sphere, raising serious concerns about the war encroaching on India's maritime neighbourhood.
- The Trump administration included the destruction of Iran's navy among its stated war aims, directly impacting the Indian Ocean's security architecture.
- Washington also reportedly armed ethnic Kurdish militias in Iran's northwest to provoke internal unrest, described as a "dangerous game" with unpredictable consequences.
- India initially did not condemn the assassination of Iran's Supreme Leader Khamenei but has faced growing pressure to take a more emphatic stand against the war and work with other powers to de-escalate.

Strait of Hormuz and India's Energy Security
The Strait of Hormuz is the world's most critical oil transit chokepoint, with approximately 20 million barrels per day flowing through it -- about 20% of global petroleum liquids consumption. For India, approximately 40-50% of crude oil imports and nearly 90% of LPG imports transit through this strait. The 2026 disruptions to the Strait of Hormuz have been described as the largest energy supply disruption since the 1970s energy crisis. India has since rerouted approximately 70% of its crude imports away from the strait, but remains deeply vulnerable to prolonged closures.
- India is the world's third-largest crude oil importer, depending on imports for over 85% of its oil needs
- Top Middle Eastern suppliers: Iraq, Saudi Arabia, UAE, Kuwait
- Nearly 50% of India's crude imports historically transited via Hormuz
- India's Strategic Petroleum Reserves (SPR) at Visakhapatnam, Mangalore, and Padur provide limited buffer (approximately 9.5 days of imports)
Connection to this news: The Israeli-American war against Iran directly threatens the Strait of Hormuz, the single most important energy transit route for India, making this conflict an existential energy security concern for New Delhi.
India-Iran Bilateral Relations and Chabahar Port
India and Iran share a multifaceted relationship dating back to the establishment of diplomatic ties in 1950, anchored in civilisational, cultural, and strategic dimensions. The centrepiece of contemporary cooperation is the Chabahar Port project, for which India and Iran signed a 10-year operational contract in May 2024. Chabahar serves as India's gateway to Afghanistan and Central Asia, bypassing Pakistan. It also forms a critical node of the International North-South Transport Corridor (INSTC), linking Mumbai to Moscow via Iran, Azerbaijan, and Russia.
- INSTC agreement signed in 2000 by India, Iran, and Russia as a multi-modal transport network
- Chabahar Port development: India committed to developing the Shahid Beheshti terminal
- Chabahar-Zahedan railway line planned to connect the port with Iran's internal railway network
- India's bilateral trade with Iran includes crude oil imports, agricultural products, and connectivity projects
Connection to this news: The war against Iran puts India's strategic investments in Chabahar and the INSTC at direct risk, potentially undermining years of diplomatic engagement and connectivity planning.
India's Indian Ocean Strategy and Maritime Security Doctrine
India considers itself the "net security provider" in the Indian Ocean Region (IOR), a concept articulated in successive defence and maritime doctrines. The Indian Ocean Naval Symposium (IONS), Information Fusion Centre for the Indian Ocean Region (IFC-IOR) at Gurugram, and the SAGAR (Security and Growth for All in the Region) doctrine launched in 2015 reflect India's commitment to a free, open, and rules-based maritime order. The U.S. military action in the Indian Ocean challenges this framework by introducing great power conflict into India's primary zone of strategic interest.
- SAGAR doctrine (2015): Cooperative framework for Indian Ocean security
- IFC-IOR: Maritime domain awareness centre established in 2018
- India operates naval facilities or agreements in Mauritius (Agalega), Seychelles (Assumption Island), Oman (Duqm), and Madagascar
- Quad (India, US, Japan, Australia) partnership includes Indian Ocean maritime security cooperation
Connection to this news: The expansion of the U.S.-Iran theatre into the Indian Ocean directly challenges India's position as the primary security provider in the IOR and complicates the India-U.S. maritime partnership under the Quad framework.
