What Happened
- Saudi Arabia's Defence Ministry reported intercepting more than 60 drones since midnight on March 16, in the context of the expanding Iran war affecting the entire Gulf region.
- Iran has kept the Strait of Hormuz closed to ships from the US, Israel, and their Western allies since March 2, 2026, with the new Supreme Leader Mojtaba Khamenei vowing to maintain the blockade as a "tool of pressure."
- President Trump pressured NATO members and China — as major consumers of Gulf oil — to contribute warships to a coalition force aimed at securing passage through the strait.
- Trump stated that countries receiving oil through the Hormuz Strait "must take care of that passage," framing it as a collective responsibility.
- Analysts have noted that Trump's coalition call appears to mask the absence of a comprehensive US plan for a closure scenario.
- Global crude oil prices have risen more than 10% since the war began on February 28, with Brent crude trading above $120 per barrel.

The Strait of Hormuz: World's Most Critical Oil Chokepoint
The Strait of Hormuz is a narrow waterway between Iran to the north and Oman's Musandam exclave to the south, connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. It is classified by the US Energy Information Administration (EIA) as the world's most important oil transit chokepoint.
- Approximately 20 million barrels per day (mb/d) of crude oil and petroleum products transited the strait in 2025 — about one-fifth of global oil consumption
- Flows represent more than one-quarter of total global seaborne oil trade
- The strait is about 30 miles (50 km) wide at its narrowest navigable point; shipping uses two 2-mile-wide lanes designated by the International Maritime Organization (IMO)
- Qatar exports approximately 93% of its LNG and the UAE 96% of its LNG through the strait
- China and India combined received 44% of all oil exports through the strait
- Alternative routes — the Suez Canal, the East-West Pipeline in Saudi Arabia (IPSA), the UAE's Habshan-Fujairah pipeline — can substitute only a fraction of the diverted flow
Connection to this news: Iran's closure of the strait to US and allied ships is the biggest weaponisation of this chokepoint in history. Even a partial closure sends oil prices soaring and creates physical shortages — directly impacting India, which imports 85% of its crude oil, a significant share of which transits through or is sourced from the Persian Gulf region.
India's Energy Security and the Hormuz Dependence
India is the world's third-largest oil consumer and imports approximately 85% of its crude oil needs. A significant portion of India's oil imports — including from Iraq (its largest supplier), Saudi Arabia, UAE, and Kuwait — passes through or originates near the Strait of Hormuz. The closure therefore has direct, severe consequences for Indian energy security.
- India's oil import basket in recent years: Iraq (~20%), Russia (~20%), Saudi Arabia (~17%), UAE (~5%), Kuwait (~5%)
- Iraq, Saudi Arabia, and UAE exports all transit the Strait of Hormuz
- India has strategic petroleum reserves (SPR) managed by Indian Strategic Petroleum Reserves Limited (ISPRL) with a total capacity of approximately 5.33 million metric tonnes at Visakhapatnam, Mangaluru, and Padur — roughly 9.5 days of import cover
- The IEA recommends 90 days of import cover; India is significantly below this benchmark
- The Iran war has accelerated pressure on India to diversify energy supply chains and increase SPR capacity
Connection to this news: The Strait of Hormuz closure translates directly into India's immediate energy cost — Brent above $120/barrel affects everything from petrol prices to inflation and the current account deficit. India's limited SPR cover makes rapid diversification (including the US-granted waiver to continue Russian oil imports) a matter of economic necessity.
Maritime Security Law and Freedom of Navigation
Under the United Nations Convention on the Law of the Sea (UNCLOS, 1982), all ships — including warships — enjoy the right of "transit passage" through international straits used for international navigation. The Strait of Hormuz qualifies as such an international strait. Iran's attempt to restrict transit passage is legally contested under UNCLOS.
- UNCLOS Article 38 grants all ships and aircraft the right of transit passage through international straits in the normal mode of continuous and expeditious transit
- Iran has historically contested UNCLOS interpretations and has not ratified the convention (it signed but not ratified)
- The US Freedom of Navigation Operations (FONOPs) programme regularly challenges excessive maritime claims by coastal states, including in the South China Sea and the Persian Gulf
- India ratified UNCLOS in 1995 and supports its provisions on freedom of navigation, though it has its own interpretive positions on certain archipelagic waters
- NATO's maritime force and the Combined Maritime Forces (CMF), a 44-nation naval coalition, have historically secured Gulf shipping lanes
Connection to this news: Trump's pressure on NATO and China to join a Hormuz escort coalition is effectively a call to collectively enforce UNCLOS transit passage rights against Iran's unilateral blockade — a scenario that could draw additional powers into the conflict and test the limits of collective maritime security frameworks.
