Q. Discuss the strategic significance of the Strait of Hormuz for Iran's regional deterrence posture, and examine its implications for India's energy security. (15 marks, 250-350 words)

The Strait of Hormuz, linking the Persian Gulf to the Gulf of Oman, carries about 20 million barrels per day — roughly a quarter of global seaborne oil trade [1][2]. Flanking its northern shore, Iran converts this geography into its single most potent instrument of deterrence.

Hormuz in Iran's deterrence posture - Asymmetric leverage: only Saudi Arabia's East–West pipeline (5 mb/d) and the UAE's Fujairah line (1.5 mb/d) can bypass the strait [1]. A credible closure threat therefore imposes global costs far out of proportion to Iran's conventional military weakness. - Graduated escalation: mines, fast-attack craft and anti-ship missiles held by the IRGC navy permit calibrated signalling — tanker harassment and route denial short of open war. - Coercive bargaining: disruption during the 2026 West Asia conflict pushed IEA members into a 400-million-barrel emergency stock release, the largest in the Agency's history [3] — proof that the threat buys diplomatic concessions. - Beyond oil: nearly 20% of global LNG trade, largely Qatari, transits with no alternative route [2].

Implications for India's energy security - Exposure: China and India together absorb 44% of crude exiting Hormuz [2]; supply and freight-insurance shocks feed directly into the import bill, CAD and inflation. - Sharpest residual risk is LPG: India imports about 60% of its LPG, and roughly 90% of that arrives via Hormuz [4]. - Diplomatic tightrope: balancing Iran (Chabahar), Israel and Gulf partners hosting a large Indian diaspora.

India's cushioning measures - Sourcing from about 40 countries, lifting non-Hormuz-routed crude from ~55% to about 70% [4]. - Strategic reserves, refineries running at near-full utilisation, and fast-tracked gas infrastructure [5].

Hormuz shows how a narrow waterway can substitute for hard power. For India, resilience lies not in choosing sides but in deepening supplier diversification, expanding strategic reserves, and accelerating the renewables transition — converting an inherited vulnerability into durable energy self-reliance.
