TEHRAN/MUSCAT — Iran has issued a stark warning to Oman, its most strategically vital Arab partner, over its shifting stance on the Strait of Hormuz, a critical chokepoint for global energy supplies. The escalating dispute comes as European officials weigh proposals to impose navigation fees in the waterway, a move Tehran has condemned as a U.S.-backed attempt to “internationalize” control of the strait. The tensions underscore Iran’s growing isolation in the Gulf and raise concerns about potential disruptions to oil flows that could reverberate across global markets, including India’s energy-dependent economy.
What Happened
Iranian Foreign Minister Hossein Amir-Abdollahian on Tuesday accused the United States of exerting “overt and covert pressures” on Oman to abandon its neutral posture on Hormuz security, according to statements carried by Iranian state-linked media. The remarks followed Oman’s participation in Western-backed maritime initiatives, including the U.S.-led International Maritime Security Construct (IMSC), which Tehran views as a departure from Muscat’s traditional mediation role between Iran and the West.
The dispute intensified after reports emerged that the European Union was exploring proposals to levy fees on ships transiting the Strait of Hormuz. The plan, still in preliminary stages, aims to fund enhanced security measures in the waterway, which handles roughly one-fifth of the world’s oil trade. The Guardian reported that the proposal would require approval from Gulf Cooperation Council (GCC) states, including Oman, which shares jurisdiction over the strait’s southern approach.
Iran’s foreign ministry dismissed the European plan as “ridiculous,” with Amir-Abdollahian mocking former U.S. President Donald Trump’s 2018 suggestion that ships passing through Hormuz should pay tolls to Washington. “The strait is not a toll road,” he declared, framing the proposal as part of a broader U.S. strategy to undermine Iran’s influence in the region.
Oman has not publicly endorsed the navigation fee plan but has quietly expanded security cooperation with Western powers. In 2023, Muscat joined the IMSC, a coalition aimed at deterring Iranian interference in Gulf shipping—a move that analysts say reflects Oman’s balancing act between its Western security partners and Iran, its neighbor and key economic ally.
Why It Matters
The Strait of Hormuz is one of the world’s most strategically sensitive waterways, with nearly 21 million barrels of oil passing through it daily. Any disruption—whether through military action, blockades, or regulatory changes—could trigger price spikes and supply shortages, with severe consequences for energy-importing nations like India, China, and Japan.
For Iran, the strait is both a geopolitical lever and a vulnerability. Tehran has repeatedly threatened to close the waterway in response to Western sanctions, though it has stopped short of doing so, likely due to the economic blowback on its own trade. The European proposal to impose navigation fees, if implemented, could provide Iran with a pretext to escalate its own measures, including increased harassment of commercial vessels or unilateral regulatory actions.
Oman’s role in the dispute is particularly significant. As the only Gulf state with strong ties to both Iran and the West, Muscat has historically served as a diplomatic bridge, facilitating negotiations on issues ranging from nuclear talks to prisoner swaps. However, Oman’s growing security cooperation with the U.S. and Europe—including hosting American military bases—suggests a shift in its foreign policy calculus, one that Iran views as a betrayal.
Background and Context
The Strait of Hormuz has been a flashpoint in Iran’s regional rivalry with the U.S. and its Gulf allies for decades. Under international law, the strait is considered an international waterway, with transit passage guaranteed under the United Nations Convention on the Law of the Sea (UNCLOS). However, Iran has long asserted the right to regulate traffic in the waterway, citing its territorial waters and security concerns.
Tensions have flared repeatedly in recent years, with the U.S. accusing Iran of seizing commercial vessels and conducting drone attacks on tankers. In 2019, Iran shot down a U.S. surveillance drone near the strait, bringing the two countries to the brink of conflict. Tehran has denied targeting civilian shipping, framing its actions as defensive responses to Western provocations, including sanctions and military deployments in the Gulf.
Oman’s relationship with Iran is rooted in economic and geopolitical pragmatism. The two countries share a maritime border and have cooperated on issues ranging from trade to counterterrorism. Oman was a key facilitator of the 2015 Iran nuclear deal (JCPOA) and has resisted pressure from Saudi Arabia and the UAE to join their anti-Iran bloc. However, Muscat’s deepening ties with the U.S., including a 2023 defense cooperation agreement, have strained its neutrality.
Competing Claims and Uncertainty
The dispute over the Strait of Hormuz is marked by competing narratives and unresolved legal questions.
– Iran’s Position: Tehran insists it has the right to regulate traffic in the strait, citing its territorial waters and security concerns. It has dismissed Western accusations of interference as propaganda and framed the European navigation fee proposal as a U.S.-backed plot to “internationalize” control of the waterway. Iran has also accused Oman of abandoning its neutral stance under U.S. pressure, though Muscat has not publicly confirmed any shift in policy.
– Western Position: The U.S. and its European allies argue that the Strait of Hormuz is an international waterway under UNCLOS, meaning no single country can unilaterally regulate or tax traffic. The proposed navigation fees are framed as a security measure to deter Iranian interference, though critics argue they could set a dangerous precedent for other strategic waterways. The U.S. has also accused Iran of using the strait as a tool of coercion, pointing to its history of vessel seizures and drone attacks.
– Oman’s Dilemma: Muscat has not publicly taken sides in the dispute but has quietly expanded security cooperation with the West. Oman’s foreign ministry has emphasized its commitment to “regional stability” and “freedom of navigation,” language that aligns with Western priorities but stops short of endorsing the navigation fee plan. Analysts say Oman’s balancing act is becoming increasingly difficult as Iran’s patience wears thin.
– Legal Ambiguities: While UNCLOS guarantees transit passage through international straits, Iran’s territorial waters extend into parts of the Hormuz waterway, creating legal gray areas. Tehran has previously argued that its regulations apply to ships passing through its waters, though international law does not recognize its right to impose fees or block transit. The European proposal, if implemented, could test these legal boundaries.
What to Watch Next
1. Oman’s Response: Muscat’s next steps will be critical in determining whether the dispute escalates. If Oman publicly endorses the European navigation fee plan or deepens its security cooperation with the U.S., Iran may retaliate through economic or diplomatic measures, such as restricting Omani access to Iranian ports or reducing trade ties.
2. European Union’s Decision: The EU’s internal deliberations on the navigation fee proposal will be closely watched. If the plan moves forward, it could provoke a strong reaction from Iran, including threats to close the strait or increase harassment of commercial vessels. The EU may also face pressure from energy-importing nations, including India, to avoid actions that could disrupt oil flows.
3. U.S. Military Posture: The U.S. has maintained a significant military presence in the Gulf to deter Iranian interference in shipping. Any escalation in tensions could lead to increased U.S. patrols in the strait or even direct confrontations with Iranian forces. The U.S. has also warned that it will hold Iran accountable for attacks on commercial vessels, raising the risk of retaliatory strikes.
4. India’s Diplomatic Role: India, which relies on the Strait of Hormuz for nearly 60% of its oil imports, has traditionally avoided taking sides in Gulf disputes. However, its growing energy dependence on the region may force it to adopt a more active diplomatic role. New Delhi could seek to mediate between Iran and Oman or coordinate with other energy-importing nations to ensure the strait remains open.
5. Iran’s Economic Leverage: Tehran has previously used its control over the Strait of Hormuz as a bargaining chip in negotiations with the West. If the European navigation fee plan moves forward, Iran may respond by increasing its own regulatory measures, such as requiring ships to obtain Iranian permits or pay “security fees.” Such actions could trigger a tit-for-tat escalation with the U.S. and its allies.
Conclusion
The dispute over the Strait of Hormuz is a microcosm of the broader geopolitical tensions shaping the Gulf. Iran’s warning to Oman reflects its growing anxiety about losing influence in the region as traditional allies like Muscat deepen ties with the West. The European proposal to impose navigation fees, while still in its early stages, has already sharpened divisions and raised the stakes for all parties involved.
For energy-importing nations like India, the stakes could not be higher. Any disruption to oil flows through the strait would have immediate and severe economic consequences, underscoring the need for diplomatic efforts to de-escalate tensions. However, with Iran’s regional isolation deepening and Western powers unwilling to cede control of the waterway, the path to a resolution remains fraught with uncertainty.
The coming months will test Oman’s ability to maintain its delicate balancing act, Iran’s willingness to tolerate Western encroachment on its perceived sphere of influence, and the international community’s capacity to prevent a crisis that could send shockwaves through global energy markets.
