What Happened

The US administration threatened to seize Kharg Island — Iran's primary oil export terminal accounting for approximately 90% of Iranian crude exports — as part of escalating military pressure on Iran.
A US naval blockade of Iran has been in effect since mid-April 2026, encompassing Iran's coastline and intercepting vessels suspected of violating the blockade.
Iran's Parliament Speaker warned that any attack on Kharg Island would trigger retaliatory strikes on regional energy infrastructure and markets.
US airstrikes on Iran entered a second consecutive day, targeting Iranian military surveillance capabilities, communication systems, and air defense sites across the country.
The US administration indicated it seeks "total control" of Iran's oil and gas sector, drawing comparisons to earlier actions against Venezuela.

Kharg Island — Iran's Singular Oil Export Node

Kharg Island is a continental island located approximately 25 kilometres off Iran's southwest coast in the Persian Gulf, and roughly 660 kilometres northwest of the Strait of Hormuz. It functions as the nerve centre of Iran's oil export infrastructure: approximately 90% of Iran's crude oil exports pass through its terminals, which can simultaneously load up to 10 supertankers and store up to 30 million barrels of crude. Iran's deep-water coastline is rare in the Gulf; Kharg's deep surrounding waters enable long jetties for supertanker mooring, a geographic advantage unavailable along most of the Iranian littoral. No other major oil-producing country is comparably dependent on a single export node — Saudi Arabia, Kuwait, and the UAE each maintain distributed export infrastructure.

Location: Persian Gulf, ~25 km off Iran's southwest coast; ~8 km long, 4–5 km wide
Handles ~90% of Iranian crude exports and tens of billions of dollars in annual government revenue
Storage capacity: up to 30 million barrels
Can load 10 supertankers simultaneously; exports include crude oil, LPG, and fertilisers
Targeted during the Iran-Iraq War (1980–88) in repeated strikes; survived and resumed operations

Connection to this news: A seizure or destruction of Kharg Island would effectively halt Iranian oil exports and could trigger immediate global energy price spikes, directly connecting this military development to global macroeconomic stability.

The Strait of Hormuz — Critical Maritime Chokepoint

The Strait of Hormuz is a narrow waterway connecting the Persian Gulf to the Gulf of Oman and the wider Indian Ocean. At its narrowest, the Strait is approximately 38 kilometres wide. Roughly 20% of the world's oil supply — and a historically higher share of seaborne traded oil (~35%) — transits through it daily, making it the world's most strategically significant maritime chokepoint. Countries bordering the Strait include Iran, Oman, and the UAE. India, the world's third-largest crude oil importer, historically sourced approximately 45% of its crude oil imports through this corridor.

Width at narrowest point: ~38 km
~20% of global oil supply transits the Strait daily
Countries on the littoral: Iran (north), Oman and UAE (south)
India's crude oil dependence through Hormuz (pre-crisis baseline): ~45%; reduced to ~30% through diversification by mid-2026
India's LPG imports through Hormuz: ~90%; LNG imports: >50%

Connection to this news: A US seizure of Kharg Island would sever Iran's oil export capacity entirely, potentially triggering Iranian retaliation by closing the Strait of Hormuz, which would disrupt global energy markets and pose acute energy security risks to oil-importing nations including India.

US Naval Blockade and International Maritime Law (UNCLOS)

The United Nations Convention on the Law of the Sea (UNCLOS, 1982) enshrines the right of "transit passage" for all ships through international straits used for navigation between two parts of the high seas or EEZs (Article 38). The Strait of Hormuz qualifies as such an international strait. Under UNCLOS, transit passage is continuous and expeditious and cannot be suspended by coastal states. The US, notably, has not ratified UNCLOS (though it treats most provisions as customary international law), while Iran is a party to UNCLOS. A naval blockade is recognised under the laws of armed conflict as a lawful belligerent measure, but must be formally declared, enforced impartially, and must not cut off neutral states' access to essential goods.

UNCLOS adopted: 1982; entered into force: 1994; 168 parties (US is a non-party but accepts most provisions as customary law)
UNCLOS Article 38: right of transit passage through international straits
UNCLOS Article 110: warships may board foreign vessels on high seas only for piracy, slave trade, unauthorised broadcasting, statelessness, or same-nationality vessels — sanctions evasion is not listed
US blockade declared: mid-April 2026, encompassing the entirety of Iran's coastline
Contested legality: critics argue the blockade violates freedom of navigation principles

Connection to this news: The US blockade and threat to seize Kharg Island raise acute questions under international maritime law about the legality of interdicting neutral commercial vessels and the right of transit passage through the Strait of Hormuz.

Global Oil Markets and Energy Security Interdependence

Iran's oil production before the current conflict stood at approximately 3.4 million barrels per day (mb/d), accounting for roughly 3–4% of global supply. However, given Iran's geographic position astride the Strait of Hormuz, its ability to threaten traffic through the Strait gives it leverage far beyond its own production share. Approximately 20 mb/d of oil and petroleum products transit the Strait daily. The threat to Kharg Island, combined with the active blockade, has direct implications for global crude oil prices, inflation, and the current account positions of oil-importing nations.

Iran's pre-crisis oil production: ~3.4 mb/d (~3–4% of global supply)
Daily oil transit through Hormuz: ~20 mb/d (~20% of global oil supply)
Global oil price benchmark: Brent Crude
India is the world's third-largest oil importer; energy import bill is a key driver of current account deficit
Iran also possesses the world's second-largest natural gas reserves and fourth-largest proven oil reserves

Connection to this news: Destruction of Kharg Island would eliminate Iran's oil export capacity, removing ~3–4% of global supply from markets and potentially triggering a crisis across the Strait that would imperil the other 17% of global oil transiting nearby.
