Hormuz Strait Control: Iran's Post-War Maritime Ambitions and Global Repercussions

Iran's Post-Conflict Vision for Hormuz: Asserting Control Amidst Legal and Economic Hurdles

In a move that has garnered significant international attention, Iran has articulated its intention to continue overseeing maritime transit through the critical Strait of Hormuz, even after the conclusion of any potential hostilities. Officials, including Deputy Foreign Minister for Legal and International Affairs, Kazem Gharibabadi, have stated that such supervision would not entail restrictions, but rather aims to facilitate safe passage and enhance services for vessels traversing this vital waterway. This assertion comes amidst Iran's escalating claims of jurisdiction over the Strait, recently compounded by proposals to levy transit fees on passing ships.

The Strait's Current Reality: Stalled Commerce and Prohibitive Costs

The on-the-ground scenario paints a stark picture. Tankers, container ships, and bulk carriers form dense lines on the horizon, trapped within the Persian Gulf since the commencement of hostilities against Iran over a month ago. In contrast, the deep blue waters a mere 40 miles off the Iranian coast remain conspicuously empty. Prior to the conflict, the Strait averaged over a hundred vessel transits daily; now, only a handful manage to navigate it. These passage often necessitate deviations into Iranian territorial waters and frequent payment of substantial "transit fees" to the regime.

Hormuz: Iran's Economic and Strategic Chess Piece

The Strait of Hormuz, once responsible for one-fifth of global oil supply, has evolved into Iran's most potent leverage against the United States, its Gulf neighbors, and even the global economy. Iran's success in enduring the current conflict and its post-war standing are intrinsically linked to its ability to maintain control over the Strait, thereby holding the key to global energy markets. Scholars like Vali Nasr, a professor at Johns Hopkins University and former U.S. State Department official, argue that the Strait has superseded Iran's nuclear program in strategic importance, serving as its sole deterrent and primary revenue source.

Tehran's Ambitious Agenda: Tolls and a New Maritime Order

Iran's ambitious plans include the advancement of legislation within its parliament, mandating transit fees for all vessels and prohibiting passage for ships from "unfriendly" nations into the Persian Gulf. The objective is to compel countries like European nations and Japan to lift economic sanctions and to permanently expel the U.S. Navy from Gulf waters. Ebrahim Azizi, chairman of the parliamentary committee on national security, has stated that while the Strait will reopen, it will be "only for those who comply with Iran's new law."

A Legal Discrepancy: Hormuz vs. Suez

Iranian officials have drawn parallels between their proposed toll system and the Suez Canal, which generates billions for Egypt annually. However, international maritime law experts, such as Professor James D. Fry of the University of Hong Kong, highlight fundamental differences. The Strait of Hormuz is a natural passage, unlike an artificial canal cutting through sovereign territory. Iran controls only one coastline, with the other belonging to Oman's Musandam exclave. Fry asserts that "no legal rationale justifies Iran's right to regulate maritime shipping on Oman's side."

Conflicting Signals from Washington: Threats and Contradictions

U.S. President Donald Trump's public statements have presented a contradictory stance. On one occasion, he suggested that European and Asian nations, reliant on Gulf oil, should take responsibility for reopening the Strait. Hours later, he tweeted about potentially "blasting Iran into oblivion" until the Strait was "completely free and open." The deployment of thousands of additional U.S. Marines and Army soldiers to the Middle East, potentially for ground operations to force the Strait open, underscores the escalating tensions and risks of significant casualties, given Iran's use of drones, missiles, and fast boats.

Geopolitical Catastrophe: A Looming Threat to Regional and Global Stability

Hasan Alhasan, a senior fellow at the International Institute for Strategic Studies and former national security official in Bahrain, warns that if Iran retains control of the Strait post-conflict, it would represent a geopolitical disaster for U.S. allies in the Middle East and globally. He elaborates that Iran could impose selective sanctions at will, jeopardizing shipping whenever it desires, effectively holding Gulf nations' economies and global energy security hostage. This scenario would leave Iran "wounded but still threatening, resentful, and hostile to most regional states."

Mitigation Efforts and Regional/International Dynamics

Gulf states have actively sought to mitigate the impact of potential Strait blockades. Saudi Arabia has rerouted some oil exports via pipelines to Red Sea ports, while the UAE has directed its oil to Fujairah on the Gulf of Oman, a major oil and gas hub that continues loading operations despite an early drone-induced fire. In the neighboring Khor Fakkan port, miles-long queues of trucks await cargo unable to reach Dubai. In the UAE town of Al-Ghayl near the Strait, posters depict rulers surrounded by military might, with slogans expressing national resilience.

European and Asian nations have shown little interest in joining any U.S. military action to reopen the Strait. French President Emmanuel Macron stated that a military solution is unrealistic and that freedom of navigation must be restored through coordination with Iran. While GCC states possess considerable naval and air power, diplomats and officials indicate they are unlikely to wage war with Iran over the Strait without significant U.S. involvement.

However, with the participation of regional powers like Turkey, Egypt, and Pakistan, and broad international support, these Gulf states could exert substantial political and economic pressure on Tehran to ensure free passage. Even Iran's closest ally, Russia, has indicated that any arrangements for the Strait must have the unanimous consent of all its littoral states.

Piracy and Global Interdependence: The Consequences of Control

Mehran Haghirian, research director at the Bourse & Bazaar think tank, describes Iran's potential forceful control of the Strait post-conflict as akin to piracy, predicting it would lead to Iran's complete isolation. He questions how GCC states could passively accept Iran controlling their lifeline, stating, "The conflict would not be confined to the GCC states but would extend to the entire international community, from Indonesia and Burkina Faso to Colombia—every country depends on the Strait of Hormuz in one way or another."

The Sanctions Conundrum: A Financial Minefield

A more immediate practical challenge arises from the designation of Iran's Islamic Revolutionary Guard Corps (IRGC) as a terrorist organization by numerous countries, including the U.S. and EU members. Financial transactions with Iran, including any potential transit fee payments, are subject to U.S. sanctions, making it a prohibitive risk for major global shipping companies. Professor Jason Chuah, a maritime law expert at City, University of London, notes, "In this absurd era of maritime 'protection money,' shipowners face peril if they don't pay, but risk their future in the global financial system if they do. Iran is demanding not just a toll, but a loyalty test – a test no commercial entity can pass."

In essence, Iran's aspirations for control over the Strait of Hormuz present a complex geopolitical and economic challenge. While Tehran seeks to leverage its position, it confronts significant international opposition and legal, financial hurdles that could result in deeper isolation rather than the realization of its objectives.
