Iran Threatens to Close Major US Oil Route: 20 Million Barrels at Risk? Amid escalating Middle East tensions, speculation is resurfacing about Iran blocking the Strait of Hormuz, a critical oil chokepoint. The commander of Iran's Revolution Guard's navy said on Tuesday that Iran could close the major oil shipping route known as the Strait of Hormuz if necessary. This statement has reignited concerns about potential disruptions to global oil supplies. The Strait of Hormuz remains a key lane for Middle Eastern oil and gas shipments from the Persian Gulf.

Is Closure Likely? The possibility of Iran shutting down the Strait of Hormuz appears remote, despite the threats. Here's why. While Iran seems to be moving towards the potential closure of the Strait of Hormuz, several factors suggest this is unlikely to occur imminently. For now, it is important to assess the context and potential consequences.

Oil Supply at Stake: The Strait of Hormuz is a critical waterway, facilitating a significant portion of global oil transport. Disruption would have a dramatic global economic impact. Though it produced an average of 2.9 million barrels a day in 2025 of crude oil, according to the Energy Information Administration, the implications extend far beyond Iran's own production.

US Response and International Presence: The U.S. and European naval presence in the Strait of Hormuz is substantial, acting as a deterrent and safeguarding international shipping lanes. 3:19 Iran reacts after Trump warns of any actions that could destabilize the region. Any attempt to close the Strait would likely face strong opposition.
