Latest news on the Strait of Hormuz: Iran blockade, tanker attacks, oil crisis, shipping disruption, Persian Gulf chokepoint, and global energy security.

The Strait of Hormuz is the only sea passage linking the oil-rich Persian Gulf to the Gulf of Oman and the Arabian Sea. Just 34 kilometres wide at its narrowest point, it handles roughly 20% of global oil and liquefied natural gas (LNG) trade — around 20 million barrels of crude per day. Saudi Arabia, Iraq, Kuwait, Iran, the UAE, and Qatar all depend on this narrow shipping lane to export energy to world markets, with around 84% of flows typically destined for Asia.

In early 2026, the Strait of Hormuz became the centre of the most serious disruption to global energy flows in decades. Following US and Israeli airstrikes on Iran in late February, Iran's Islamic Revolutionary Guard Corps (IRGC) declared the waterway closed to international shipping, launched multiple attacks on merchant vessels, and reportedly laid sea mines in the strait. A US-brokered ceasefire provided brief relief, with the strait momentarily reopening in April 2026, but Iran reimposed restrictions within hours, citing an ongoing blockade of its ports by the United States. Hundreds of tankers and cargo ships were left stranded in the Gulf, with ship tracking data showing daily transits reduced to single figures.

The economic consequences of the disruption have been far-reaching. Oil prices surged sharply as markets priced in the uncertainty, while Asian nations — which receive the bulk of Persian Gulf crude — drew on strategic reserves. Countries such as Pakistan sought emergency alternative supply routes, and the disruption to Qatar's LNG exports posed challenges for European gas markets already sensitive to supply shocks. The Persian Gulf's role as a hub for global fertiliser exports — accounting for a significant share of internationally traded urea and ammonia — further amplified the economic stakes.

The strait has a long history as both a vital trade artery and a geopolitical flashpoint. The 1980s Tanker War — in which Iran and Iraq attacked oil tankers during the Iran-Iraq War, prompting US naval intervention under Operation Praying Mantis — established the precedent of international forces protecting freedom of navigation here. Iran has repeatedly threatened closure during nuclear negotiations and in response to Western sanctions, using the chokepoint as leverage without carrying out a full blockade until 2026. The UAE and Saudi Arabia have developed bypass pipelines — including the Abu Dhabi Crude Oil Pipeline and the Saudi East-West Pipeline via Yanbu — but their combined capacity covers only a fraction of normal strait volumes.

The strait falls primarily within the territorial waters of Iran and Oman, giving Iran a significant strategic advantage in controlling or disrupting transit. The IRGC navy has a history of seizing tankers and harassing commercial vessels in the waters around the strait, and the 2026 crisis has intensified debate about international maritime law, the limits of naval deterrence, and the role of the US Fifth Fleet based in Bahrain. For energy-importing nations worldwide, the crisis has renewed pressure to diversify supply routes and reduce dependence on a single chokepoint.
