Quick Revision: The Strait of Hormuz is a legally defined ‘strait used for international navigation’ under UNCLOS, through which 20-30% of global seaborne oil transits; its disruption poses systemic risks to energy security and global trade.

Why is this in the news?

The reported strike by Iran’s Revolutionary Guard Corps (IRGC) on a Togo-flagged oil tanker in the Strait of Hormuz underscores the persistent geopolitical volatility in a critical maritime chokepoint. This incident, occurring amid heightened regional tensions, highlights the fragility of global oil supply chains and the strategic importance of maritime security governance. It also prompts examination of the legal and operational frameworks governing transit through international straits, as well as the role of external powers in safeguarding commercial shipping in high-risk zones.

Background

• The Strait of Hormuz is a narrow maritime passage between the Persian Gulf and the Gulf of Oman, through which approximately 20-30% of the world’s seaborne oil passes, making it one of the most strategically vital chokepoints in global energy trade.
• The strait lies within the territorial waters of Iran and Oman, and its legal status is governed by the United Nations Convention on the Law of the Sea (UNCLOS), which provides for the right of innocent passage through straits used for international navigation.
• Tensions in the Strait of Hormuz have escalated in recent years due to geopolitical rivalries, including the US-Iran conflict, regional proxy wars, and the targeting of commercial vessels by state and non-state actors.
• Maritime security incidents in the Strait of Hormuz and adjacent waters (e.g., Gulf of Aden) have prompted nations to deploy naval assets for protection of commercial shipping, including South Korea’s Cheonghae Unit and the US-led maritime security initiatives.

What is the Strait of Hormuz and Why is it Strategically Significant?

• The Strait of Hormuz is a 39-kilometre-wide waterway connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea, serving as the sole maritime route for oil exports from several Gulf states, including Saudi Arabia, Iraq, the UAE, Kuwait, and Iran.
• Under the United Nations Convention on the Law of the Sea (UNCLOS), the strait is classified as a ‘strait used for international navigation,’ entailing the right of ‘transit passage’ for all vessels, including military ships, subject to the requirement that such passage is not prejudicial to the peace, good order, or security of the coastal states.
• Approximately 20-30% of global seaborne oil transits the Strait of Hormuz daily, with an estimated 17 million barrels passing through on average, making it a critical node in the global energy supply chain.
• The strait’s strategic importance is amplified by the concentration of oil and gas reserves in the Persian Gulf, which account for nearly one-third of the world’s proven oil reserves and one-fifth of its natural gas reserves.
• Geopolitical tensions in the region, including sanctions, military posturing, and asymmetric warfare tactics (e.g., drone strikes, limpet mine attacks), have periodically disrupted maritime traffic, raising concerns about energy security and supply chain resilience.
• The legal framework governing the strait is complemented by regional and international maritime security initiatives, such as the US-led International Maritime Security Construct (IMSC) and the European Union’s Operation Atalanta in the Gulf of Aden, aimed at safeguarding commercial shipping.
• The Strait of Hormuz is flanked by critical infrastructure, including major oil terminals (e.g., Ras Tanura in Saudi Arabia) and military bases, which are often targeted in regional conflicts, further underscoring its geopolitical salience.
• Oman, as the southern littoral state, plays a pivotal role in managing regional maritime security, including through its control of the Musandam Peninsula and participation in confidence-building measures with Iran.

Key Features

Feature	Significance
Strait of Hormuz	A critical chokepoint for global oil transit, handling approximately 20-30% of the world’s seaborne oil shipments, making its security vital for international energy markets.
Iranian Revolutionary Guard Corps (IRGC) assertion	Tehran’s claim of control over the Strait reflects its strategic posture in the Persian Gulf, influencing regional maritime security dynamics and geopolitical negotiations.

Why it Matters

Economic/Strategic

• Disruption in the Strait of Hormuz can trigger volatility in global oil prices, impacting inflation, fuel costs, and economic growth in energy-dependent nations.
• The Strait’s closure or heightened tensions could reroute oil shipments, increasing transportation costs and supply chain delays for major economies.
• South Korea’s consideration to expand naval operations reflects the economic imperative to protect its energy imports and export routes, particularly from the Middle East.
• Maritime insurance premiums for vessels transiting the region are likely to rise, reflecting elevated risk perceptions among underwriters.

Geopolitical

• Iran’s assertion of control over the Strait underscores its leverage in regional negotiations, particularly regarding nuclear diplomacy and sanctions relief.
• The involvement of external naval powers (US, South Korea) introduces complexities in balancing sovereignty, freedom of navigation, and collective security.
• The Houthis’ actions in the Gulf of Aden demonstrate the interconnectedness of conflicts in Yemen, Iran, and broader maritime security in the Indian Ocean region.

Legal/Institutional

• The principle of ‘freedom of navigation’ under the United Nations Convention on the Law of the Sea (UNCLOS) is central to resolving disputes over maritime access.
• Regional and international institutions (e.g., International Maritime Organization) play a critical role in establishing norms for safe and secure shipping in contested waters.

Challenges

1. Maritime Security Threats

• Escalation of attacks on commercial vessels risks destabilising global energy markets and supply chains.
• The proliferation of non-state actors (e.g., Houthis) complicates traditional naval deterrence strategies.
• Limited enforcement mechanisms for maritime security in the absence of a unified regional or international response.
