Strait of Hormuz as a Maritime Chokepoint

The Strait of Hormuz is a narrow sea passage at the mouth of the Persian Gulf. It links the Persian Gulf with the Gulf of Oman and, through it, the Arabian Sea and wider Indian Ocean. It is called a maritime chokepoint because a very large volume of energy trade must pass through a confined navigational space, so any disruption can affect global shipping, oil and gas prices, and energy security.

Constitutional / legal basis

No specific Indian constitutional provision applies. The relevant legal framework is international maritime law, especially UNCLOS Part III on straits used for international navigation, which recognises the regime of transit passage through such straits.

Key points

• Location: it lies between the Persian Gulf to the west/north-west and the Gulf of Oman to the east/south-east, forming the main sea exit from the Gulf region.
• Bordering states: Iran lies on the northern side; Oman’s Musandam Peninsula lies on the southern side; the United Arab Emirates is on the adjoining southern/western approaches to the strait.
• Strategic energy route: it is the principal seaborne outlet for petroleum exports from major Gulf producers such as Saudi Arabia, Iraq, Kuwait, the UAE, Qatar, Iran and others.
• Gas significance: it is also important for liquefied natural gas movements, especially from Qatar, one of the world’s major LNG exporters.
• Chokepoint character: its narrow geography and concentrated shipping lanes make traffic vulnerable to military tension, mining, blockade threats, accidents, and higher insurance or freight costs.
• Global impact: disruption in the strait can quickly affect international oil and gas markets because alternative export routes from the Gulf are limited and cannot fully substitute for seaborne flows through Hormuz.
• Relevance for India: India’s energy imports, trade with the Gulf, and maritime security interests in the western Indian Ocean make stability around the Strait of Hormuz a direct strategic concern.
