The Strait of Hormuz has become a war zone following US-Israeli attacks on Iran, disrupting 20% of global oil and 25% of LNG trade, with Iran imposing restrictive measures under UNCLOS 'Innocent Passage' clause, challenging global maritime law and energy security.

Key points

Strait of Hormuz connects the Persian Gulf to the Gulf of Oman, qualifying as an international strait under UNCLOS, with its entire navigable corridor within Iran and Oman's territorial waters, making it a critical chokepoint for global energy trade.

UNCLOS 1982 establishes two legal regimes for shipping: 'Innocent Passage' with stringent coastal state restrictions, and 'Transit Passage' for international straits, granting unimpeded navigation. Iran's application of 'Innocent Passage' contradicts UNCLOS's 'Transit Passage' provisions, designed to prevent unilateral blockades.

Maritime Chokepoints like Hormuz amplify naval power projection, historically pivotal in conflicts (e.g., Dardanelles in WWI). Control over such points is central to US-China-Russia strategic competition, exemplified by US interest in Greenland's GIUK Gap for Arctic dominance.

Economic Impact: Marine insurance premiums have surged 400-600%, and Iran demands $1 per barrel oil transit tolls, termed 'extortionate', severely disrupting global trade flows and energy markets.

[GS3-Economy] The crisis threatens India's energy security, as 70% of its crude imports transit Hormuz, necessitating diversification strategies and regional cooperation to mitigate supply shocks.

Legal Conflict: Iran's actions violate UNCLOS's 'Transit Passage' rights and UN Charter prohibitions on aggressive actions like mining or kinetic threats, setting a dangerous precedent for international maritime law.

Historical Context: 'Pax Britannica' relied on controlling chokepoints like Gibraltar and Singapore. Today, US-China rivalry mirrors this, with China eyeing Arctic routes as extensions of its Maritime Silk Road.

Way Forward: India should advocate for UN-mediated resolution under UNCLOS, diversify energy import routes via Chabahar Port, and strengthen naval capabilities to ensure freedom of navigation in critical waterways.

Key terms

Maritime Chokepoints

Strategic narrow waterways like Hormuz, Malacca, and GIUK Gap that control global shipping routes. UPSC focus: their geopolitical importance in power projection, trade security, and historical role in conflicts, linking GS2 (IR) and GS3 (Security).

UNCLOS 1982

The United Nations Convention on the Law of the Sea establishes legal frameworks for maritime boundaries, navigation rights, and resource use. For UPSC, its significance lies in governing India's EEZ, resolving disputes like South China Sea, and ensuring freedom of navigation crucial for trade and security.

Innocent Passage

A UNCLOS provision allowing ships to traverse territorial waters if non-threatening. UPSC relevance: Coastal states can suspend it, unlike 'Transit Passage', making it a tool for geopolitical leverage, as seen in Iran's Hormuz restrictions.

Transit Passage

A UNCLOS right guaranteeing unimpeded navigation through international straits like Hormuz. For UPSC, it's vital for India's energy security and global trade, as coastal states cannot block or discriminate against vessels under this regime.
