Iran's imposition of transit fees and military control over the Strait of Hormuz threatens global energy security and challenges international maritime law, with 20% of global oil trade passing through this chokepoint.
Key points
Strait of Hormuz is a critical maritime chokepoint connecting the Persian Gulf and Arabian Sea, facilitating 20 million barrels of oil daily (20% of global supply) and a third of global LNG trade, making it vital for energy security.
Iran's asymmetric strategy includes charging $2 million transit fees, deploying fast attack crafts (FACs), and leveraging anti-ship missiles to enforce its claim that passage is a privilege, not a right under UNCLOS.
UNCLOS vs. Geneva Convention: Iran exploits its non-ratification of UNCLOS (1982) to invoke the 1958 Geneva Convention's 'innocent passage' clause, allowing unilateral suspension of transit if deemed a security threat.
Historical precedent: The Kingdom of Hormuz (10th-13th centuries) similarly monetized the strait through tolls, while British colonial interests later commercialized it for spice trade, underscoring its enduring geopolitical value.
Territorial sovereignty: Iran argues navigable lanes fall within its 12-nautical-mile territorial sea, rejecting the UNCLOS 'transit passage' principle for international straits, a stance contested by global powers.
[GS3-Economy] Disruptions in Hormuz could spike global oil prices, impacting India's import bill (85% oil dependency) and inflation, necessitating diversification of energy routes like Chabahar or INSTC.
Islamic Revolutionary Guard Corps (IRGC) has militarized the strait since the 1979 Revolution, using sea mines, missile batteries, and island acquisitions (Greater/Lesser Tunb) to project power.
Way Forward: Global consensus must enforce UNCLOS transit rights, India should accelerate strategic oil reserves (currently 9.5 days cover), and multilateral naval patrols (excluding US) could de-escalate tensions while ensuring free navigation.
Key terms
- UNCLOS (1982)
- United Nations Convention on the Law of the Sea establishes 'transit passage' rights in international straits, ensuring unimpeded navigation. Iran's non-ratification creates legal grey areas relevant for GS2 (Polity) questions on treaty adherence.
- Innocent Passage (Geneva Convention 1958)
- Allows coastal states to suspend navigation if deemed threatening, unlike UNCLOS' non-suspendable transit. This distinction is pivotal for GS2 questions on maritime sovereignty vs. global commons.
- Islamic Revolutionary Guard Corps (IRGC) Navy
- Iran's parallel naval force specializing in asymmetric warfare (fast attack crafts, mines). Its role in Hormuz exemplifies non-state actors' impact on global security (GS3), with implications for India's West Asia policy.
- Strait of Hormuz
- A 33-km wide maritime chokepoint between Iran and Oman, critical for global oil transit (20% of supply). Its control allows Iran to leverage energy security as geopolitical tool, impacting GS2 (international relations) and GS3 (energy security).

Answer framework
Introduction
Briefly introduce the strategic importance of the Strait of Hormuz as a global energy chokepoint and Iran's increasing control over it.
Impact on Global Energy Security
Disruption of 20% of global oil supply and a third of LNG trade, leading to potential price volatility.
Increased energy insecurity for oil-dependent economies like India, which relies on 85% imports.
Need for alternative routes like Chabahar or INSTC to mitigate risks.
Challenges to International Maritime Law
Iran's exploitation of non-ratification of UNCLOS to enforce transit fees and military control.
Conflict between UNCLOS 'transit passage' rights and Iran's invocation of 'innocent passage' under the Geneva Convention.
Legal grey areas created by Iran's unilateral actions, undermining global maritime norms.
Geopolitical and Strategic Implications
Iran's use of asymmetric strategies (fast attack crafts, anti-ship missiles) to project power.
Role of the Islamic Revolutionary Guard Corps (IRGC) in militarizing the strait.
Potential for escalation and need for multilateral naval patrols to ensure free navigation.
Conclusion
Suggest a balanced approach involving global consensus on UNCLOS enforcement, strategic oil reserves, and diplomatic efforts to de-escalate tensions while ensuring energy security.
