Trump's Proposed Toll on Strait of Hormuz Could Cost Supertankers $34 Million

Riyadh, Saudi Arabia Jul 14, 2026 ALN: US President Donald Trump's recent proposal to impose a 20 percent fee on ships transiting the Strait of Hormuz has sparked significant debate and concern within the international shipping community and among oil-producing nations. The Strait of Hormuz is a critical maritime chokepoint, through which approximately 20 percent of the world's oil and gas flows, making it a strategic waterway for global energy supplies. Given its importance, any changes to the operational framework surrounding this strait can have far-reaching consequences for international trade and energy security.

By suggesting that the United States should be reimbursed for its role as the "guardian of the Hormuz Strait," Trump has positioned the US military presence in the region as a service that warrants compensation from vessels using the strait. This proposal, however, raises serious questions about the legality and practicality of such a toll system, as well as its potential economic implications for both shipping companies and oil-exporting nations. The concept of charging for passage through a natural waterway is unprecedented and could lead to significant shifts in how international maritime law is interpreted and enforced.

To understand the financial impact of the proposed fee, it is essential to consider the economics of oil transportation. A Very Large Crude Carrier (VLCC) typically carries around two million barrels of crude oil. With Brent crude oil prices hovering around $85 per barrel, the value of a single cargo can reach approximately $170 million. Thus, a 20 percent levy translates to about $34 million per voyage, a significant cost that could disrupt the economics of oil transport and, by extension, global oil markets. The increase in transportation costs could lead to higher prices for consumers and potentially affect the overall demand for oil if producers decide to absorb these costs or pass them on to end-users.

Experts have expressed concern over the implications of such a high fee. Amena Bakr, a maritime data analyst, highlighted that a 20 percent charge is unprecedented and excessive. She noted that no country has the authority to impose tolls on a natural waterway like the Strait of Hormuz. This sentiment is echoed by the UN International Maritime Organization, which has firmly opposed any fees for passage through straits utilized for international navigation, asserting that there is no legal foundation for mandatory tolls in such contexts. The potential for the US to unilaterally impose a toll could lead to significant backlash from other nations and could undermine the principles that govern international maritime law.

Historically, tolls have been applied to man-made waterways such as the Suez and Panama Canals, where transit fees have been established and regulated. In contrast, the Strait of Hormuz is a natural strait, and the introduction of a toll system could set a concerning precedent for international maritime law and navigation rights. The implications of this precedent could extend beyond the Strait of Hormuz, potentially encouraging other nations to seek similar arrangements in their own waters, thereby complicating global shipping routes and increasing costs across the board.

In fact, Iran had previously attempted to implement a toll system, colloquially referred to as the "Tehran tollbooth" system, which sought to charge about $2 per barrel for vessels transiting the strait. However, this system faced significant challenges, and few ship owners reportedly complied with the fees. The Iranian toll system was managed by an entity linked to the Islamic Revolutionary Guard Corps, which vetted vessels and collected fees, often in cryptocurrencies or Chinese yuan, further complicating the financial landscape for shipping companies operating in the region. The failure of this system underscores the difficulties in enforcing tolls on natural waterways and the potential resistance from shipping companies and nations dependent on these routes.

In response to Trump's proposal, Iranian Foreign Minister Abbas Araghchi acknowledged the need for compensation for safe passage through the Strait of Hormuz but criticized the proposed 20 percent fee as excessive. This response highlights the contentious nature of maritime security in the region, where geopolitical tensions frequently influence shipping operations and safety. The Iranian perspective is particularly relevant given the country's strategic interests in the Gulf and its historical role as a regional power.

One of the most pressing concerns surrounding Trump's toll proposal is the lack of clarity regarding its enforcement mechanisms. Analysts have pointed out that the White House has not provided details on how the United States would calculate, collect, or enforce the proposed transit fee. Questions remain about whether payment would be required prior to entering the strait, whether it would be tied to naval escorts, and how it would be enforced through shipping companies, insurers, banks, and port authorities. The potential for increased costs associated with compliance could ultimately be passed down the supply chain, affecting producers, refiners, and consumers alike. The uncertainty surrounding enforcement could lead to confusion and operational challenges for shipping companies, potentially resulting in delays and increased costs throughout the maritime industry.

Moreover, Trump's assertion that countries using the strait should contribute to the costs of US protection has raised eyebrows among Gulf states, particularly the UAE, which have traditionally opposed toll systems in the waterway. Just weeks prior to Trump's announcement, US Secretary of State Marco Rubio had publicly supported the position that no country should charge tolls or fees on international waterways, underscoring the shifting dynamics of US foreign policy in the region. This inconsistency may lead to a loss of credibility for the US among its allies and partners in the region, as they may question the reliability of US commitments to uphold the principles of free navigation.

As the situation unfolds, Gulf states such as Saudi Arabia and the UAE, which have alternative export routes that bypass the Strait of Hormuz, have remained relatively silent on Trump's proposal. However, countries like Kuwait and Iraq, which are more geographically constrained and heavily reliant on the strait for energy exports, may find themselves in a difficult position, potentially compelled to comply with any new regulations or fees that could arise from the proposal. The economic ramifications for these nations could be severe, as increased transportation costs could impact their revenues and economic stability.

The implications of Trump's toll proposal extend beyond the immediate financial burden on shipping companies. The introduction of such a fee could exacerbate existing tensions in the region, leading to increased naval presence and potential confrontations in one of the world's most strategically significant maritime corridors. The potential for retaliation from Iran or other regional actors could further destabilize the situation, affecting global oil prices and supply chains. The interplay between economic interests and geopolitical tensions in this context is complex and could lead to unforeseen consequences for both regional and global stability.

In conclusion, Trump's proposal to impose a toll on vessels crossing the Strait of Hormuz raises significant legal, economic, and geopolitical questions. As the international community grapples with the implications of this proposal, it remains to be seen how it will impact maritime operations in the region and the broader dynamics of global energy markets. The situation underscores the delicate balance between maritime security and the principles of free navigation that have long governed international waters. The potential for this proposal to reshape the landscape of international maritime law and the economic relationships between nations that rely on these critical shipping routes cannot be understated, and careful consideration will be needed to navigate the complexities of this evolving issue.
