Oman Proposes Hormuz Toll Plan After U.S.-Iran Conflict

A Bold Proposal in the Wake of Conflict

In the turbulent aftermath of U.S.-Iran military confrontations that sent shockwaves across global energy markets and international shipping lanes, the Sultanate of Oman has emerged as an unlikely but pivotal diplomatic broker. According to senior officials and diplomats with direct knowledge of the matter, Oman has put forward a proposal that would allow both Iran and Oman to collect transit fees from commercial vessels navigating the Strait of Hormuz — one of the world's most strategically vital maritime chokepoints.

The proposal, if adopted, would mark a historic and deeply controversial shift in the legal and commercial framework governing one of the busiest shipping lanes on the planet. Approximately 20 to 21 million barrels of oil pass through the strait daily, representing nearly 20 percent of the world's total petroleum liquids consumption. Any change to the rules of navigation through this narrow passage between Iran and the Arabian Peninsula would have immediate and far-reaching implications for global energy prices, international trade, and the balance of naval power in the Persian Gulf.

The Strait of Hormuz: Geography and Geopolitical Weight

The Strait of Hormuz, at its narrowest point only about 33 kilometers wide, separates Iran to the north from Oman and the United Arab Emirates to the south. Its strategic importance has been recognized for centuries, but in the modern era it has become synonymous with energy security for the entire world. The strait is the only sea passage from the Persian Gulf to the open ocean, making it the lifeblood of oil exports from Saudi Arabia, the UAE, Iraq, Kuwait, and Iran itself.

Iran has periodically threatened to close the strait during periods of heightened tensions with the United States and its allies. In 2012, during the height of Western sanctions pressure, Iranian naval commanders warned of blockading the waterway if further economic pressure was applied. More recently, during tensions in 2019, a series of tanker seizures and attacks near the strait raised global alarm. Each time, U.S. naval forces in the region — centered around the Fifth Fleet headquartered in Bahrain — have served as the primary guarantor of freedom of navigation.

Oman's Unique Diplomatic Role

Oman has long cultivated a distinctive foreign policy posture in the Middle East: neutral, pragmatic, and often quietly indispensable. Unlike most of its Gulf Cooperation Council neighbors, Oman maintained diplomatic ties with Iran even during periods of maximum regional hostility and served as a back-channel for the negotiations that led to the 2015 Joint Comprehensive Plan of Action (JCPOA), the landmark nuclear deal between Iran and world powers.

It was in Muscat that American and Iranian officials met secretly for preliminary discussions before those negotiations went multilateral. Oman's Sultan, first Qaboos bin Said and now Haitham bin Tariq, has consistently positioned the sultanate as a bridge between Iran and the Arab world, between the Gulf states and Tehran, and between Washington and its adversaries.

Now, following what officials describe as a significant escalation between U.S. and Iranian forces — the details of which continue to emerge — Oman appears to be leveraging its unique position once again. The Hormuz fee plan is described by sources as part of a broader diplomatic package aimed at stabilizing the region and providing Iran with economic relief without requiring a full normalization of relations with the United States.

The Economics of the Proposal

The mechanics of the proposed fee system remain unclear from what has been disclosed publicly, but officials familiar with the plan suggest it would involve a structured toll mechanism whereby commercial vessels — particularly oil tankers and liquefied natural gas carriers — would pay a fee upon transiting the strait. Iran and Oman would split the revenue, providing Tehran with a significant income stream that could help offset the impact of ongoing U.S. sanctions.

The economic incentive for Iran is substantial. Even a modest per-vessel transit fee, applied to the thousands of ships that traverse the strait annually, could generate billions of dollars per year for the Iranian government. For Oman, which has been working to diversify its own economy away from oil revenues, the proposal offers both financial benefit and enhanced geopolitical relevance.

However, legal experts and maritime law scholars have immediately raised red flags. Under the United Nations Convention on the Law of the Sea (UNCLOS), ships enjoy the right of transit passage through international straits, a right that explicitly precludes coastal states from imposing fees or levies on transiting vessels. Iran, notably, is not a signatory to UNCLOS, which complicates the legal picture considerably.

International Reactions and the Risk of Escalation

The proposal has already prompted cautious but pointed responses from major maritime powers. The United States, European Union member states, Japan, South Korea, China, and India — all of which depend heavily on unimpeded oil flows through Hormuz — are watching the development closely. Washington has historically treated freedom of navigation through international straits as a near-inviolable principle, one it has been willing to defend with military force.

China, which has deepened its strategic partnership with Iran through a 25-year cooperation agreement signed in 2021, faces a particularly complex calculation. Beijing imports a significant share of its oil through the strait and has no interest in seeing transit costs rise, yet it also has an interest in seeing Iran economically stabilized and politically engaged with its neighbors rather than in open conflict with the United States.

Gulf Arab states, particularly Saudi Arabia and the UAE, have reacted with significant unease. Any arrangement that legitimizes Iranian co-sovereignty over the strait — even in an economic rather than military sense — is seen as a dangerous precedent that could embolden Tehran's broader regional ambitions. Riyadh has reportedly conveyed its concerns directly to Muscat.

What Comes Next

Diplomats caution that the Oman proposal is in its early stages and faces substantial hurdles before it could be implemented. International legal challenges, the opposition of major maritime powers, and the internal political dynamics of Iran — where hardliners may see the proposal as insufficient and moderates may see it as an opportunity — all represent significant obstacles.

Nevertheless, the very fact that the proposal has been floated signals that a new phase of post-conflict diplomacy is underway in the Persian Gulf. Whether it leads to a durable arrangement or collapses under the weight of competing interests, the Hormuz fee plan illustrates the degree to which the recent U.S.-Iran confrontation has reshuffled the geopolitical deck in one of the world's most volatile regions.
