Oman walks a diplomatic tightrope over Strait of Hormuz fees, creating a ‘blind spot’ for markets

MUSCAT, Oman – Oman, long celebrated as the "Switzerland of the Middle East" for its deft neutrality, is now at the center of a high-stakes geopolitical contest that could reshape the economics of global energy transport. The sultanate is employing a deliberately opaque strategy in sensitive talks with Iran over a new maritime security framework for the Strait of Hormuz, a move that analysts warn is creating a dangerous "blind spot" for financial markets.

The discussions, which follow a wartime blockade of the strait that sent shockwaves through the global economy, reportedly include the possibility of imposing transit fees on the world's most critical oil chokepoint. This has placed Oman in a perilous position, caught between its powerful neighbor Iran and its key security partner, the United States, which has threatened to "aggressively" impose sanctions over any such plan.

As commercial vessels once again anchor off Port Sultan Qaboos, the quiet diplomatic maneuvering in Muscat carries profound implications for the 20% of the world's oil that typically transits the narrow waterway.

A Question of Governance

Following the devastating energy crunch triggered by the strait's closure, Oman has reprised its role as a crucial intermediary between Tehran and Washington. Its unique position as a trusted interlocutor for both sides has been central to negotiations aimed at restoring the free flow of commerce.

However, joint talks with Iran on a "new maritime security order" have raised alarms. The core of the issue lies in Iran's long-held ambition to gain international recognition of its control over the strait, which, according to senior Iranian sources cited by Reuters, includes the ability to levy fees on all ships entering or leaving the Gulf.

• The Legal Hurdle: International maritime law, specifically the principle of "transit passage," governs straits used for international navigation. This principle ensures the right of free and unimpeded passage and does not permit coastal states to charge tolls simply for transit.

• The Proposed Workaround: Analysts suggest that Iran and Oman may be exploring a way to circumvent this legal barrier by introducing "service fees" rather than "tolls." These fees could ostensibly be for services such as vessel traffic management, security escorts, or environmental protection, creating a legal gray area that could be tested on the international stage.

Oman has publicly stated that any agreement will comply with international law, but the ambiguity has done little to calm nerves in Washington and other global capitals.

The Market's 'Blind Spot'

While markets are adept at pricing in the risk of physical disruptions like blockades or military conflict, the current situation presents a different, more nuanced challenge.

"Markets tend to price disruption risk but pay less attention to governance risk. That creates a blind spot," Neil Quilliam, an associate fellow at the Chatham House think tank, told CNBC.

This governance risk—the potential for a fundamental change in how the strait is managed and paid for—is not being fully factored into oil prices or shipping costs. Dania Thafer, executive director of the Gulf International Forum, noted that Oman's unclear position is a calculated diplomatic strategy.

"You have a regional power, such as Iran, and then you have a global power, the U.S., putting pressure on Oman," Thafer said. "So, they're trying to use a degree of strategic ambiguity to try to stay out of the conflict as much as possible and not undermine these very strong players."

A High-Stakes Triangle: Oman, Iran, and the U.S.

The diplomatic pressure on Oman is immense, with the U.S. and Iran holding diametrically opposed positions.

• Iran's Ambition: Tehran is fixated on winning the right to charge fees. This would not only provide a new revenue stream but also serve as a powerful symbol of its regional sovereignty and influence.

• Washington's Red Line: The U.S. has unequivocally rejected the idea. U.S. President Donald Trump's administration has previously threatened sanctions against Oman if it facilitates an Iranian tolling system. Treasury Secretary Scott Bessent reiterated this stance in a May 28 post on X, stating, "All nations should reject outright any efforts by Iran to disrupt the free flow of commerce." A memorandum of understanding signed on June 17 between the U.S. and Iran explicitly forbids Tehran from imposing tolls during a 60-day negotiation period for a permanent settlement.

• Oman's Predicament: "Oman's reputation as a mediator has left it increasingly trapped," said Andrew Leber, a non-resident scholar at the Carnegie Middle East Program. He noted that Omani diplomats have been seen "tacking back and forth between insisting no toll will be charged, and suggesting that ships might be asked to pay a fee which will be called something other than a toll."

Oman is not a disinterested party. Its geography gives it a direct stake in the strait's security and governance. According to Leber, the sultanate has both security and financial incentives to either support Iran's plan or implement its own fee structure, provided it receives a share of the revenue.

What Happens Next

The path forward remains uncertain. While the prospect of fees is a political disappointment for many international actors, Thafer suggests that if a system is implemented that guarantees safe passage, markets would likely "respond accordingly" and adapt to the new cost. The key for traders and shippers is predictability and safety, even if it comes at a price.

As of June 21, several Chinese-owned vessels have reportedly been able to transit the strait, a sign of tentative progress following President Trump's announcement that Iran would allow an initial 20 ships to pass.

For now, the world is watching Muscat. Oman's next move will determine whether it can successfully broker a lasting peace that satisfies all parties or if its diplomatic tightrope act will snap, plunging the world's most vital energy artery back into crisis. The "blind spot" analysts have identified could soon come into sharp focus, with significant consequences for the global economy. A spokesperson for Oman's Foreign Ministry was not available to comment.
