What Happened
- US President Donald Trump indicated the United States would assist in clearing "traffic buildup" in the Strait of Hormuz following the US-Iran two-week ceasefire agreed on April 7–8, 2026.
- Despite the ceasefire, Iran's Islamic Revolutionary Guard Corps (IRGC) continued to exercise control over the strait, with Iran announcing safe passage would be possible "via coordination with Iran's Armed Forces and with due consideration of technical limitations."
- Trump stated the US's key red line: the Strait of Hormuz must be opened "completely, immediately, and safely" — without limitations or tolls.
- Iran's position implied the strait would remain under its "smart management," suggesting continued IRGC oversight and potential transit fees for vessels.
- Shipping traffic through the strait remained more than 90% below normal levels even after the ceasefire, with bulk carriers beginning to transit while oil tankers sought clarity.

Strait of Hormuz: Strategic Geography and International Law
The Strait of Hormuz is a narrow waterway between Iran (to the north) and Oman and the UAE (to the south), connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. It is the world's most critical maritime chokepoint for energy trade. In 2024, approximately 20 million barrels per day (b/d) of oil — about 20% of global petroleum consumption — transited the strait. Around one-fifth of global LNG trade also passes through it.
Under the United Nations Convention on the Law of the Sea (UNCLOS), Article 38 guarantees ships the right of "transit passage" through international straits used for international navigation — a right that cannot be suspended, unlike "innocent passage" in territorial waters.
- Location: Between Iran (north) and Oman/UAE (south)
- Narrowest navigable width: approximately 33 km (21 miles)
- Oil flow: ~20 million barrels/day (~20% of global petroleum consumption) in 2024
- LNG trade: ~19% of global LNG trade passes through (primarily Qatari and UAE LNG)
- UNCLOS Article 38: guarantees right of transit passage through international straits
- Iran is NOT a signatory to UNCLOS
Connection to this news: Iran's continued "smart management" of the strait after the ceasefire directly challenges the international law principle of unimpeded transit passage, creating a new flashpoint even as hostilities paused.
IRGC and Iran's Maritime Strategy
The Islamic Revolutionary Guard Corps (IRGC) controls Iran's maritime forces in the Persian Gulf and Strait of Hormuz through its Naval branch. Iran has periodically used the threat of Hormuz closure as a strategic lever against the US and Gulf states. During the 2019–2020 US-Iran tensions following Trump's withdrawal from the JCPOA, Iran seized multiple tankers in the strait.
- IRGC Naval branch (IRGCN) patrols the Persian Gulf and Strait of Hormuz
- The US designated the IRGC as a Foreign Terrorist Organisation (FTO) in April 2019
- Iran periodically uses tanker seizures and strait threats as coercive diplomacy
- In 2019, Iran seized the British tanker Stena Impero
Connection to this news: The IRGC's continued operational control of the strait — even during the ceasefire — signals Iran intends to retain the strait as a strategic bargaining chip in ongoing negotiations.
India's Energy Exposure to Hormuz
India is among the most exposed major economies to Strait of Hormuz disruptions. India's oil import dependence is approximately 85%, with ~55% sourced from West Asia. The 2026 Hormuz closure forced many Indian refiners to seek costlier alternative supplies from West Africa and the Americas, contributing to inflationary pressures and a widening current account deficit.
- India imports ~85% of crude oil requirements
- ~55% of India's crude oil comes from West Asian sources
- Strait of Hormuz closure affected shipping costs and availability for India's east and west coast refineries
- Key buyers of Gulf crude: Indian Oil Corporation (IOC), Bharat Petroleum (BPCL), HPCL
Connection to this news: Any continued Iranian "management" of the strait — including tolls or coordination requirements — will increase shipping costs for Indian refiners and delay normalisation of energy supply.
