India Iran Relations

1. Introduction

India and Iran share a civilisational relationship spanning centuries, which has evolved into a strategic partnership based on energy security, regional connectivity and stability in West Asia. Iran occupies a crucial geopolitical position, connecting the Persian Gulf, Central Asia, the Caucasus and Afghanistan. For India, Iran is strategically important because of the Chabahar Port, the International North-South Transport Corridor (INSTC) and its potential role as an energy supplier. Despite challenges arising from US sanctions, India has continued diplomatic engagement with Tehran while balancing its expanding partnership with the United States and other Gulf countries. India Iran Relations are therefore strategically important for India’s connectivity, energy security and regional interests.

In recent years, the US–Iran conflict, sanctions and military tensions have significantly affected India Iran Relations. The conflict has complicated India’s connectivity projects, disrupted regional trade routes and increased uncertainty over the future of Chabahar Port. At the same time, instability around the Strait of Hormuz, through which a major share of India’s energy imports passes, has highlighted Iran’s strategic significance for India’s energy and maritime security. Consequently, India’s policy towards Iran is guided by strategic autonomy, balancing geopolitical interests with economic and security priorities.

2. Areas of Cooperation

Strategic Connectivity and Regional Cooperation

• Chabahar Port is the cornerstone of India Iran Relations, providing India direct access to Afghanistan, Central Asia and Eurasia while bypassing Pakistan. This makes it an important topic in India–Iran Relation BPSC Notes pdf.
• In May 2024, India and Iran signed a 10-year agreement for the operation of the Shahid Beheshti Terminal at Chabahar, reaffirming India’s long-term commitment to the project.
• Chabahar serves as India’s gateway to the International North-South Transport Corridor (INSTC), a multimodal corridor linking India–Iran–Caspian Sea–Russia–Europe, reducing transportation time and logistics costs.
• The port complements India’s Connect Central Asia Policy by facilitating trade with Kazakhstan, Uzbekistan, Turkmenistan and the Caucasus region.
• Chabahar is strategically important as a counterbalance to China’s Gwadar Port in Pakistan, strengthening India’s geopolitical presence in the Arabian Sea.
• India and Iran are also cooperating on the Chabahar–Zahedan rail link, which will integrate the port with the INSTC and enhance regional connectivity.
• During the recent US–Iran tensions, India continued diplomatic engagement with both Washington and Tehran to safeguard its strategic interests at Chabahar, underlining the port’s importance for India’s connectivity objectives.
• Despite sanctions-related uncertainties, both India and Iran have reiterated their commitment to keeping Chabahar operational as a key regional connectivity hub. India Iran Relations therefore remain closely linked with India’s connectivity strategy and are highly relevant for India–Iran Relation BPSC Notes pdf.

Energy and Economic Cooperation

• Energy security has traditionally been the backbone of India Iran Relations, with Iran once being among India’s top three crude oil suppliers before US sanctions halted imports in 2019.
• Iran possesses the world’s second-largest natural gas reserves and among the largest crude oil reserves, making it a strategically important long-term energy partner for India.
• India is interested in resuming imports of crude oil, LNG and petrochemicals as sanctions ease, which can diversify India’s energy basket and reduce transportation costs due to Iran’s geographical proximity.
• Following the recent easing of US restrictions, India and Iran have revived discussions on oil and gas cooperation during the BRICS Energy Ministers’ Meeting (2026).
• Iranian crude is attractive because it is competitively priced, suits several Indian refineries and historically offered longer credit periods.
• Beyond hydrocarbons, bilateral trade includes fertilisers, pharmaceuticals, rice, tea, engineering goods and chemicals.
• Both countries have explored alternative payment mechanisms (such as rupee-based settlements) to reduce the impact of sanctions and banking restrictions.
• Revival of normal trade relations could boost India’s energy security, reduce import costs and strengthen economic engagement with West Asia. India Iran Relations therefore remain important for India’s economic and energy interests and are a key area in India–Iran Relation BPSC Notes pdf.

Strategic, Maritime and Diplomatic Cooperation

• India and Iran cooperate to promote peace, stability and security in West Asia, recognising the region’s importance for India’s energy security and trade. India Iran Relations are therefore important to India’s wider West Asia policy.
• Iran is strategically located along the Persian Gulf and near the Strait of Hormuz, through which nearly one-fifth of global crude oil trade passes, making maritime stability vital for India.
• Both countries support greater regional connectivity through initiatives such as the International North-South Transport Corridor (INSTC) and cooperate in multilateral forums like the Shanghai Cooperation Organisation (SCO) and BRICS.
• India maintains regular diplomatic engagement with Iran while following a policy of strategic autonomy, balancing relations with Iran, the United States, Israel and Gulf countries.
• Cooperation also includes counter-terrorism, combating drug trafficking, maritime security and regional stability in Afghanistan after the Taliban’s return to power.
• During the recent US–Iran tensions, India called for dialogue, restraint and peaceful resolution, emphasising the importance of freedom of navigation, uninterrupted energy supplies and regional stability.
• Stable India–Iran relations strengthen India’s role as a responsible stakeholder in West Asia and support its long-term strategic interests in connectivity, energy and maritime security. India Iran Relations therefore form an important part of India–Iran Relation BPSC Notes pdf.

3. Challenges / Issues

US–Iran Conflict and Sanctions

• The US–Iran conflict is rooted in disputes over Iran’s nuclear programme, ballistic missile development, regional influence and US economic sanctions. India Iran Relations are directly affected by these geopolitical tensions.
• After the US withdrew from the Joint Comprehensive Plan of Action (JCPOA) in 2018, it re-imposed stringent sanctions on Iran, severely affecting Iran’s oil exports, banking system and international trade.
• Recent military confrontations between the United States and Iran have further intensified instability in West Asia, increasing the risk of a wider regional conflict and threatening global energy supplies.
• The conflict has directly affected India–Iran relations, as India must balance its strategic partnership with the United States while preserving long-term interests in Iran under its policy of strategic autonomy.
• US sanctions forced India to stop importing Iranian crude oil in 2019, despite Iran previously being one of India’s largest oil suppliers.
• Financial sanctions have disrupted banking channels, insurance services, shipping and payment mechanisms, reducing bilateral trade and investment.
• The uncertainty created by sanctions has slowed progress on the Chabahar Port and the International North-South Transport Corridor (INSTC), both critical to India’s connectivity strategy.
• Although India signed a 10-year agreement for operating the Shahid Beheshti Terminal in 2024, renewed US sanctions and recent military tensions have created uncertainty over the project’s future.
• During the latest US military strikes in Iran, reports suggested attacks near Chabahar Port. However, India’s Ministry of External Affairs (MEA) clarified that the Indian-operated Shahid Beheshti Terminal was not damaged, while continuing discussions with relevant stakeholders to safeguard India’s interests.
• The conflict has also increased geopolitical competition in West Asia, making it more difficult for India to simultaneously deepen relations with Iran, Israel, the Gulf countries and the United States.
• Despite these challenges, India has consistently called for dialogue, restraint, de-escalation and peaceful resolution of disputes, emphasising respect for international law, freedom of navigation and regional stability rather than taking sides in the conflict. India Iran Relations therefore require a careful balance between strategic interests and geopolitical constraints. This section is also important for India–Iran Relation BPSC Notes pdf.

Impact of the US–Iran Conflict on India

A. Energy Security

• India imports around 85–90% of its crude oil, with a significant share sourced from West Asia; hence any conflict in the region directly threatens India’s energy security. India Iran Relations are therefore closely linked to India’s energy security.
• The Strait of Hormuz, through which nearly 20% of global crude oil and LNG trade passes, is India’s most critical energy chokepoint. Any disruption can delay supplies and increase transportation costs.
• Rising geopolitical tensions lead to higher crude oil prices, increasing India’s import bill and dependence on costlier alternative suppliers.
• India has been compelled to diversify crude imports from countries such as Russia, the US, Brazil and African producers to reduce dependence on the Gulf region. India Iran Relations therefore have wider implications for India’s energy strategy and economic stability.

B. Economic Impact

• Higher crude oil prices widen India’s Current Account Deficit (CAD) and increase the country’s import bill. India Iran Relations are therefore closely connected with India’s economic stability.
• Rising fuel prices contribute to inflation, increasing transportation, logistics and manufacturing costs across the economy.
• The conflict puts pressure on the Indian Rupee, as higher oil imports increase demand for US dollars.
• Increased government expenditure on fuel subsidies and fertilisers may widen the fiscal deficit.
• Investor sentiment weakens during geopolitical crises, increasing volatility in the stock and foreign exchange markets. India Iran Relations therefore have wider economic implications for India.

C. Trade and Connectivity

• Maritime insecurity in the Persian Gulf and the Strait of Hormuz disrupts India’s trade with West Asia, Europe and Central Asia. India Iran Relations are therefore closely connected with India’s trade and connectivity interests.
• Shipping delays, higher freight charges and increased marine insurance premiums raise the cost of imports and exports.
• Strategic connectivity projects such as the Chabahar Port and the International North-South Transport Corridor (INSTC) face implementation delays due to sanctions and regional instability.
• Supply-chain disruptions adversely affect imports of crude oil, LNG, fertilisers and petrochemicals. India Iran Relations remain important for maintaining India’s alternative connectivity routes and regional trade.

D. Strategic and Foreign Policy Impact

• The conflict complicates India’s policy of strategic autonomy, as India seeks to maintain strong relations simultaneously with Iran, the United States, Israel and Gulf countries. India Iran Relations are therefore shaped by India’s need to balance multiple strategic partnerships.
• India must carefully balance its energy interests, security cooperation with the US, and strategic partnership with Israel, while preserving long-standing ties with Iran.
• Regional instability reduces India’s diplomatic space and complicates its broader West Asia policy. India Iran Relations therefore remain important to India’s strategic and foreign policy calculations.

E. Maritime Security

• Escalation in the Persian Gulf increases threats to Indian commercial vessels, oil tankers and merchant shipping. India Iran Relations are therefore closely linked with India’s maritime security and freedom of navigation.
• Greater deployment of naval forces by regional and global powers raises the risk of accidental escalation and disruption of sea lanes.
• India has strengthened maritime surveillance and coordinated naval deployments to safeguard its shipping and energy routes. India Iran Relations remain important for protecting India’s maritime and energy interests in the region.

F. Indian Diaspora and Consular Concerns

• Nearly 9 million Indians live and work across the Gulf region, making their safety a major foreign policy priority during regional conflicts. India Iran Relations are therefore also linked to the welfare and security of the Indian diaspora in West Asia.
• Escalating hostilities increase the possibility of evacuation operations, disruptions to employment and remittance flows.
• India has issued travel advisories, monitored the security situation closely and maintained readiness for evacuation if required. India Iran Relations remain important in this context because instability in the region can directly affect Indian citizens and India’s consular responsibilities.

G. Overall Strategic Implications

• The conflict reinforces the importance of energy diversification, Strategic Petroleum Reserves (SPR) and renewable energy development. India Iran Relations are therefore important for India’s long-term energy security.
• It highlights the need to accelerate alternative connectivity initiatives such as the INSTC and strengthen India’s maritime capabilities in the Indian Ocean.
• The crisis demonstrates that stability in West Asia remains critical for India’s energy security, economic growth, trade, diaspora welfare and national security. India Iran Relations consequently remain strategically important for India’s wider regional interests.

Other Bilateral Challenges

• Declining Bilateral Trade: Trade between India and Iran remains below its potential due to prolonged US sanctions, banking restrictions and limited private-sector investment. India Iran Relations are therefore constrained by financial and economic restrictions.
• Slow Progress of Connectivity Projects: Although the Chabahar Port and the International North-South Transport Corridor (INSTC) are strategically important, their full potential is yet to be realised because of sanctions, financing constraints and regional instability.
• China’s Growing Influence: Iran’s 25-year Comprehensive Strategic Partnership with China and its growing participation in the Belt and Road Initiative (BRI) have increased China’s economic and strategic footprint in Iran, creating competition for India’s regional interests.
• Banking and Payment Constraints: Restrictions on international banking systems and insurance services continue to hamper trade, investment and project implementation.
• Regional Instability: Conflicts involving Iran–Israel, Iran–US, and tensions involving proxy groups in West Asia create an uncertain environment for long-term economic cooperation.
• Limited Energy Cooperation: Despite Iran’s vast oil and gas reserves, India has been unable to fully utilise this potential because of sanctions and geopolitical uncertainties.
• Afghanistan Factor: Political instability in Afghanistan affects the effectiveness of Chabahar Port and the INSTC as gateways to Central Asia.
• Balancing Major Powers: India faces the challenge of maintaining strong relations with Iran, the United States, Israel and Gulf countries simultaneously without compromising its strategic interests. India Iran Relations therefore require careful diplomatic balancing.

4. Way Forward

• Expedite the operationalisation of Chabahar Port and integrate it fully with the INSTC to strengthen connectivity with Central Asia and Europe. India Iran Relations can be strengthened through reliable regional connectivity.
• Diversify energy sources while remaining prepared to resume energy cooperation with Iran whenever international conditions permit.
• Expand cooperation in fertilisers, petrochemicals, pharmaceuticals, renewable energy and digital trade to reduce dependence on crude oil.
• Strengthen alternative banking and payment mechanisms to facilitate bilateral trade within the framework of international regulations.
• Deepen maritime cooperation to ensure the security of sea lanes in the Persian Gulf and the Arabian Sea.
• Continue India’s policy of strategic autonomy, engaging constructively with Iran, the US, Israel and Gulf countries.
• Use platforms such as BRICS, SCO and the INSTC framework to enhance regional connectivity and economic cooperation.
• Support peaceful resolution of regional conflicts through dialogue and diplomacy while safeguarding India’s energy security, trade and diaspora. India Iran Relations should continue to be guided by India’s strategic interests and policy of strategic autonomy.

5. Conclusion

India–Iran relations remain strategically important despite challenges arising from US sanctions and the US–Iran conflict. Iran is indispensable for India’s energy security, regional connectivity and access to Central Asia through Chabahar Port and the INSTC. At the same time, escalating tensions in West Asia have exposed India’s vulnerability to disruptions in energy supplies, maritime trade and regional stability. Going forward, India must continue pursuing strategic autonomy, balancing relations with all major stakeholders while strengthening connectivity, energy diversification and diplomatic engagement to protect its long-term national interests. India Iran Relations will therefore remain an important component of India’s strategic, economic and foreign policy interests.
