The Strait of Hormuz plays a critical role in the global oil supply, with 20% of oil and gas transiting through this vital route. If Iran were to close the strait, it would trigger significant economic disruptions worldwide, impacting major economies like China, India, and Japan, while raising oil prices and triggering inflation. Experts discuss the feasibility and implications of such an act, noting potential responses from the U.S. and the development of alternative routes.

Speculations arise as Iran may consider blocking the Strait of Hormuz in retaliation for U.S. actions against its nuclear facilities, causing global economic uncertainties.
The Strait of Hormuz is a significant geopolitical focal point, with around 20% of global oil and gas traversing this narrow passage. Recent speculation suggests that Iran may consider closing this critical shipping lane in retaliation against U.S. strikes on its nuclear sites, a move that could have substantial repercussions for both regional and global economies. As approximately 20 million barrels of oil flow through the strait daily, the blockade could dramatically disrupt international trade, elevate oil prices, and increase costs for goods and services worldwide.
The Strait is geographically positioned between Iran to the north and Oman and the United Arab Emirates (UAE) to the south. Its limited width—barely 50 kilometers at its entrance and only 33 kilometers at its most constricted points—adds to its strategic importance, enabling it to accommodate large crude oil tankers operated by major oil producers in the Middle East. In 2023, oil transported through the Strait has been valued at nearly $600 billion annually.
Should Iran decide to close the strait, experts suggest that the action would create "uncharted terrain" for the global economy. Sir Alex Younger, former head of MI6, emphasized the economic challenges that would arise from such a closure, particularly regarding oil prices and stock market reactions.
Countries such as Saudi Arabia—who depend heavily on this route to export around six million barrels per day—would be adversely affected, as would Asian nations like China, which sources about 90% of its imported Iranian oil through the strait. With the economic stability at stake, rising oil prices could lead to an increase in manufacturing costs in China, potentially triggering inflation worldwide as production costs ripple through supply chains.
Experts highlight several scenarios where Iran could block the strait, including using fast attack boats and submarines to lay mines or initiate military engagements against commercial vessels. Despite these capabilities, analysts believe that the U.S. and its allies could promptly restore shipping operations through robust military actions. Historical precedents, such as the tanker wars of the late 1980s during the Iran-Iraq war, could serve as a guide in managing potential conflicts in this strategic waterway.
Interestingly, while Iran has threatened to close the strait in past conflicts, such actions were never fully realized. U.S. Secretary of State Marco Rubio argues that doing so would equate to "economic suicide" for Iran and has called upon China to intervene and discourage such a blockade. Analysts warn that disrupting the flow of oil through the Strait of Hormuz could alienate Iran's Gulf neighbors and provoke significant backlash from critical trade partners like China.
To mitigate risks associated with the Strait, Gulf countries have increasingly invested in alternative routes for oil exportation. For example, Saudi Arabia’s East-West pipeline and the United Arab Emirates’ pipeline connecting to the Gulf of Oman are designed to facilitate oil transport independent of Hormuz. These alternative routes could collectively handle about 3.5 million barrels daily, yet they still represent only a portion of current shipments through the strait.
In conclusion, while the prospect of Iran closing the Strait of Hormuz looms as a severe threat to the global oil supply, the complexity of geopolitical relationships and economic interdependence may deter such drastic measures. The situation remains fluid, requiring monitoring as tensions evolve and global energy policies adapt.
