Context: India and Iran share deep civilisational ties rooted in centuries of cultural exchange and trade interactions. In the contemporary geopolitical context, their relationship is driven primarily by connectivity interests, energy security needs, and India’s strategic autonomy in West Asia. However, the partnership also faces several geopolitical and economic constraints.

Strategic Importance of Iran for India

1. Connectivity to Afghanistan and Central Asia

1. The Chabahar Port provides India with direct access to Afghanistan and Central Asia by bypassing Pakistan.
2. The port strengthens India’s regional connectivity strategy and enhances trade outreach toward Eurasia.
3. It also supports Iran’s economy by generating transit revenues under sanctions pressure.

2. Role of the International North-South Transport Corridor (INSTC)

1. The International North-South Transport Corridor connects India with Russia and Europe through Iran via a multimodal transport network.
2. It reduces transportation time and cost compared to traditional maritime routes.
3. It enhances Iran’s importance as a transit hub and supports India’s Eurasian engagement.

3. Energy Security Cooperation

1. Iran possesses one of the world’s largest oil reserves and has historically been a reliable crude supplier to India.
2. India used mechanisms such as the rupee–rial arrangement to continue oil trade during sanctions.
3. Energy cooperation helps India diversify its import basket and strengthen long-term energy security.

4. Maritime Security Cooperation

1. Stability in the Arabian Sea and the Strait of Hormuz is critical for India’s energy imports and trade flows.
2. Cooperation with Iran helps secure maritime chokepoints and shipping lanes essential for India’s economy.

5. Support for Strategic Autonomy in West Asia

1. India has maintained balanced relations with Iran alongside partnerships with the United States and Israel.
2. Under S. Jaishankar, India has followed a policy of multi-alignment in West Asia.
3. Even leaders such as Shashi Tharoor have acknowledged the professionalism of India’s diplomatic balancing strategy.

6. Trade and Humanitarian Cooperation

1. India exports essential commodities such as basmati rice, tea, sugar, and medicines to Iran during sanctions-induced shortages.
2. India’s pharmaceutical sector plays a stabilising role in Iran’s domestic health supply chain.
3. Such cooperation strengthens India’s credibility as a dependable partner.

Challenges in India–Iran Relations

1. Impact of US Sanctions on Iran

1. Economic sanctions imposed by the United States restrict India’s ability to expand trade and investment with Iran.
2. These sanctions disrupted India’s crude oil imports from Iran after 2019.
3. Financial restrictions complicate banking transactions and infrastructure cooperation.

2. Balancing Relations with the United States and Israel

1. India’s strategic partnership with the United States creates diplomatic constraints in expanding engagement with Iran.
2. India must carefully balance relations between competing geopolitical actors in West Asia.
3. This limits the pace and scale of cooperation with Iran.

3. Regional Instability in West Asia

1. Conflicts in the Red Sea region and tensions involving Iran create uncertainty in trade routes.
2. Instability affects maritime security and increases risks to Indian shipping and energy imports.

4. Slow Progress in Connectivity Projects

1. Infrastructure development at Chabahar Port and along the INSTC corridor has progressed more slowly than expected.
2. Sanctions-related uncertainties discourage private investment participation.

5. Economic Risks from Iran–US Confrontation

1. Escalation between Iran and the United States can disrupt global supply chains and energy markets.
2. Indian companies such as Reliance Industries may face export restrictions and refinery-related losses during geopolitical crises.

6. Competition from Other Regional Actors

1. China’s growing engagement with Iran under long-term strategic agreements creates competition for influence.
2. This may reduce India’s strategic space in Iran.

Way Forward

1. India should accelerate infrastructure development and operationalisation of Chabahar Port to strengthen regional connectivity.
2. India should fast-track the implementation of the International North-South Transport Corridor to enhance trade integration with Eurasia.
3. India should continue calibrated diplomatic engagement with Iran while maintaining strategic partnerships with the United States and Israel.
4. India should expand cooperation in pharmaceuticals, food security supplies, and infrastructure sectors.
5. India should strengthen maritime security coordination to safeguard shipping routes through the Strait of Hormuz.
6. India should leverage its strategic autonomy to play a constructive role in reducing tensions in West Asia.

Conclusion: India–Iran relations are shaped by mutual strategic necessity in connectivity, energy security, and regional diplomacy. Despite geopolitical constraints and sanctions-related challenges, the partnership remains vital for India’s long-term strategic interests. A balanced and pragmatic engagement with Iran will remain essential for safeguarding India’s geopolitical flexibility in West Asia.
