Examine how India's strategic and economic interests in West Asia are affected by instability in Iran's institutional leadership.

Iran's decision-making core has been repeatedly reconstituted since the US-Israel war of February 2026 — the death of Supreme Leader Ali Khamenei, the elevation of Mojtaba Khamenei, and the appointment of former IRGC chief Mohsen Rezaee as Secretary of the Supreme National Security Council in August 2026 [5]. For India, whose West Asia policy rests on connectivity, energy and diaspora, this churn carries direct costs.

Nature of the instability

• Three SNSC Secretaries within five months — Larijani, Zolghadr, then Rezaee — indicates wartime institutional turnover, not routine succession [5].
• Consolidation around IRGC-aligned hardliners shifts the balance from negotiation towards deterrence, reducing policy predictability.

Strategic interests affected

• Chabahar: India's only sovereign-funded port abroad, operated under the 10-year contract signed by India Ports Global Ltd with Iran's PMO in May 2024, with about $120 million in equipment and a $250 million credit window [2]. Leadership flux and re-tightened sanctions risk stalling disbursement and the INSTC link to Central Asia [1].
• Strategic autonomy: India must sustain simultaneous ties with Iran, Israel and the GCC; a hardline Tehran narrows this manoeuvring space [1].
• Maritime security: brinkmanship over the Strait of Hormuz enlarges the Indian Navy's escort and contingency-evacuation burden.

Economic interests affected

• Hormuz carries roughly one-fifth of global petroleum liquids consumption [3]; any closure threat transmits instantly into crude prices, freight and war-risk insurance for an import-dependent economy.
• Diaspora and remittances: Gulf-based Indian workers contribute close to two-fifths of India's remittance inflows, which a wider conflict would disrupt [4].
• Trade normalisation with Iran — resumed crude purchases, rupee-based settlement — remains frozen amid uncertainty [1].

India's exposure is therefore structural rather than episodic. The prudent course is de-risking without disengagement: insulating Chabahar through continued sanctions waivers, diversifying crude sourcing and strategic reserves, pre-positioning evacuation capacity, and sustaining quiet engagement with whichever leadership consolidates in Tehran. Continuity of India's civilisational and connectivity partnership with Iran, pursued alongside Gulf and Israeli ties, best serves its long-term strategic autonomy.
