Iran announces closure of Strait of Hormuz amid regional military escalation

Iran announced the closure of the Strait of Hormuz, a critical global oil transport route, amid escalating regional military tensions following attacks by the US and Israel against Iranian centers of power. The move has raised alarms in international energy markets and shipping.

Key points

• The closure was announced by Iran's Islamic Revolutionary Guard Corps (IRGC) via the Tasnim News Agency, citing strategic importance.
• The UK Maritime Trade Operations (UKMTO) received multiple reports from ships about the closure warning, allegedly from the IRGC.
• The EU naval mission 'Aspides' confirmed receiving VHF radio messages from the IRGC stating no vessel is permitted to cross the Strait.
• The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman and is vital for transporting about 20% of global oil consumption.
• The US government urged commercial vessels to avoid the Middle East region following the recent military actions.

Why it matters

The Strait of Hormuz is the world's most important oil export channel, and any prolonged disruption could immediately increase crude oil prices and risk energy supply interruptions in Asia and Europe.
