What Would Happen If Iran Closes the Strait of Hormuz Oil Corridor?

Understanding the Implications of a Potential Closure of the Strait of Hormuz

The prospect of Iran retaliating against U.S. strikes on its nuclear facilities by blocking the Strait of Hormuz is a significant concern for global economies. This narrow shipping lane is not just a mere waterway; it is a critical artery for the world’s oil and gas supply, with approximately 20% of global oil and gas passing through it. Closing this vital route would have far-reaching consequences, not only disrupting international trade but also inflating oil prices and impacting the cost of goods and services around the globe. This article delves into the geopolitical significance of the Strait of Hormuz, the potential fallout from its closure, and the strategic measures that might be taken in response.

The Geopolitical Importance of the Strait of Hormuz

Situated between Iran to the north and Oman and the United Arab Emirates (UAE) to the south, the Strait of Hormuz is one of the world's most crucial shipping channels. It serves as the only sea route for oil from the Persian Gulf to international markets. Spanning about 50 kilometers at its entrance and exit, and narrowing to around 33 kilometers at its most constricted point, this strait is deep enough to accommodate the largest crude oil tankers.

Daily Oil Flow through the Strait

As of the first half of 2023, an estimated 20 million barrels of oil traversed the Strait of Hormuz each day, which translates to nearly $600 billion in energy trade annually. This oil supply does not solely originate from Iran; it also includes contributions from other Gulf states such as Iraq, Kuwait, Qatar, Saudi Arabia, and the UAE. The closure of this strait would, therefore, represent a significant risk not just to Iran but to the entire region’s economies that heavily rely on oil exports.

Potential Economic Consequences of a Closure

Experts have expressed grave concerns regarding the economic ramifications of a potential blockade of the Strait of Hormuz. Sir Alex Younger, the former head of the UK's intelligence agency MI6, has stated that closing the strait would pose an "incredible economic problem," significantly impacting oil prices. The effects of such a blockade would ripple through global markets, inflating costs and causing stock market instability.

Effects on Major Economies

Countries like China, India, and Japan, which are among the largest importers of crude oil that passes through the strait, would be hit particularly hard. Specific impacts may include:

• Increased Oil Prices: With reduced supply, oil prices would likely skyrocket, affecting consumers and industries that depend on petroleum products.
• Inflationary Pressures: Rising fuel and production costs could lead to higher prices for goods and services across the board, further exacerbating inflation globally.
• Economic Slowdown: Key economies, especially in Asia, could face economic slowdowns as energy costs rise, impacting their manufacturing and export capabilities.

Specific Impacts on Asian Economies

Asia, in particular, would feel the brunt of a closure of the Strait of Hormuz. In 2022, around 82% of crude oil and condensates leaving the strait were destined for Asian countries. Here are some specifics:

• China: Estimated to purchase approximately 90% of Iran's oil exports, any disruption would significantly impact its energy needs.
• India: Nearly half of India's crude oil and 60% of its natural gas imports traverse the strait.
• South Korea and Japan: These countries rely on the strait for 60% and nearly three-quarters of their crude oil imports, respectively.

Strategic Military Implications

The potential for military engagement escalates with the threat of closing the Strait of Hormuz. According to experts, Iran could employ various tactics, such as laying mines or using fast attack boats and submarines, to block maritime traffic. However, this could provoke a military response from the U.S. and its allies, who have a vested interest in maintaining open shipping routes. Historical precedents, such as the "tanker war" during the late 1980s, illustrate how such conflicts can unfold.

Historical Context: The Tanker War

During the Iran-Iraq war in the late 1980s, both nations targeted neutral vessels to exert economic pressure. The U.S. eventually intervened by escorting Kuwaiti tankers through the Gulf, marking one of the largest naval operations since World War II. While Iran has consistently threatened to close the Strait of Hormuz, it has never fully executed these threats, leading some to believe that the current situation might be different.

Alternative Routes and Future Considerations

The ongoing threat of closure has prompted Gulf nations to explore alternative routes for oil exportation. According to the U.S. Energy Information Administration (EIA), several pipelines have been activated to mitigate the risk:

• Saudi Arabia's East–West Pipeline: A 1,200-kilometer pipeline capable of transporting up to 5 million barrels of crude oil per day.
• UAE's Fujairah Pipeline: This pipeline connects inland oilfields to the port of Fujairah on the Gulf of Oman, with a capacity of 1.5 million barrels per day.
• Iran's Goreh–Jask Pipeline: Designed to transport crude oil to the Gulf of Oman, currently capable of handling around 350,000 barrels per day.

Collectively, these alternative routes could accommodate approximately 3.5 million barrels of oil per day, roughly 15% of the crude currently shipped through the Strait of Hormuz. However, the effectiveness of these alternative routes in meeting global demand remains to be seen.

Conclusion

The potential closure of the Strait of Hormuz poses a serious threat to global economies, particularly for major oil-importing nations in Asia. The intricate web of geopolitical tensions, economic dependencies, and military responses creates a precarious situation that demands careful navigation. While alternative routes are being developed, the immediate fallout from a blockade would likely disrupt markets and inflate costs worldwide.

As we monitor the evolving situation, it is crucial to consider how geopolitical maneuvers can impact the daily lives of individuals and the broader global economy.
