Oman Navigates Perilous Waters Amidst US-Iran Tensions

Muscat, Oman – The Sultanate of Oman, long a beacon of diplomatic neutrality in a volatile Middle East, has found itself increasingly ensnared in the escalating tensions between the United States and Iran. With its strategic location bordering the critical Strait of Hormuz, Oman's traditional role as a discreet intermediary has been tested by the Trump administration's "maximum pressure" campaign against Tehran and recent direct warnings from the U.S. president. This precarious balancing act highlights Oman's unique foreign policy approach, its significant economic and security vulnerabilities, and the broader implications for regional stability.

The Strategic Chokepoint: Strait of Hormuz at the Epicenter

Oman’s geopolitical significance is inextricably linked to the Strait of Hormuz, a narrow maritime passage shared with Iran that connects the Persian Gulf to the Gulf of Oman and the Arabian Sea. This waterway is one of the world's most vital chokepoints, through which approximately 20% to 25% of the globe's oil and liquefied natural gas (LNG) supplies transit annually, making it indispensable for international energy security and trade. The Omani Musandam Peninsula, a non-contiguous exclave, directly abuts the Strait, giving Muscat a direct stake in its unimpeded flow. Disruptions in this strategic corridor carry the potential for severe global economic consequences, impacting oil prices and supply chains worldwide. The ongoing tensions have underscored the fragility of this critical artery, with concerns rising over its potential closure, which occurred for a period since late February.

A Legacy of Neutrality and Quiet Diplomacy

For decades, Oman has cultivated a foreign policy characterized by "active neutrality" and a philosophy of being "friends to all, enemies to none". This approach, largely shaped under the late Sultan Qaboos bin Said al-Said, has allowed Oman to maintain constructive relationships with a diverse array of international actors, including both Western powers and Iran. Unlike many of its Gulf Cooperation Council (GCC) neighbors, Oman notably refused to join the boycott of Qatar and maintained diplomatic ties with Iran even when other states severed them following regional incidents.

This unique position has enabled Oman to serve as a crucial, often unacknowledged, mediator in regional and international disputes. The Sultanate played a pivotal role in facilitating backchannel talks between the United States and Iran that ultimately led to the 2015 Joint Comprehensive Plan of Action (JCPOA), commonly known as the Iran nuclear deal. Oman has also mediated rapprochements between Saudi Arabia and Iran, and between Saudi Arabia and the Iran-backed Houthi rebels in Yemen, hosting meetings that were appreciated by the United Nations and the United States. Prior to the current conflict, Oman had hosted pre-war negotiations between the United States and Iran. This consistent commitment to dialogue has earned Muscat a reputation as a trusted interlocutor for both Washington and Tehran.

Caught in the Crosscurrents: Maximum Pressure and Direct Threats

The re-escalation of U.S.-Iran tensions under the Trump administration, particularly following the U.S. withdrawal from the JCPOA in 2018 and the subsequent implementation of a "maximum pressure" campaign, placed immense strain on Oman's diplomatic tightrope. The campaign aimed to impose intensified sanctions on Iran, seeking to constrain its nuclear program and regional activities. This pressure culminated in a "US-Israeli war on Iran" which commenced on February 28, 2026, further destabilizing the region.

In a striking development, U.S. President Donald Trump issued a direct threat to Oman on May 27, 2026, stating that the Sultanate would have to "behave" or face being "blown up" by the United States. These remarks came amidst reports that Iran and Oman were discussing a potential mechanism to jointly charge a toll for vessels transiting the Strait of Hormuz, an idea vehemently rejected by the U.S. President who insisted the Strait constituted international waters that no entity would control. This strong language from Washington signaled a significant escalation in U.S. frustration with Muscat's perceived closeness to Tehran and any potential arrangements that could grant Iran indirect influence over the strategic waterway. The U.S. Treasury Secretary Scott Bessent later affirmed that Oman had assured Washington it had no plans for such a toll, and warned against any cooperation with Iran's proposed "Strait Authority".

Omani officials have not shied away from voicing their concerns regarding the trajectory of the conflict. Foreign Minister Sayyid Badr Albusaidi penned an opinion piece in March criticizing the United States for acting against its own interests by following Israel, which he suggested sought the overthrow of the Islamic Republic. Albusaidi stated that the U.S. had "lost control of its own foreign policy" and asserted that the war was not of Iran's making, directly contradicting the Trump administration's rationale.

Economic Realities and Security Concerns

Oman's commitment to neutrality is also driven by pragmatic economic and security considerations. The country, with one of the lowest GDPs per capita within the GCC, is not an economic powerhouse like Saudi Arabia or the UAE. It has robust economic ties with Iran, including a long-standing agreement for Iran to export natural gas to Oman, with plans for a pipeline project. Bilateral trade between the two nations has prospered, with intentions to significantly increase its value. Iran views Oman as a crucial gateway to international markets for its gas exports.

However, regional instability and the U.S.-Iran conflict pose significant risks. Oman has experienced drone strikes on its port cities, and its territory has been described as being "physically situated in the crossfire". This precarious position puts its neutrality under severe strain, with some analysts suggesting that Iran views Omani territory as a legitimate target due to the U.S. military presence. While Oman's diplomatic and trade ties with the United States date back to 1833, its strategic relationship with Washington developed decades ago, yet the U.S. does not have permanent bases in Oman as it does in other Gulf states, though the U.S. Navy has access to Duqm Port.

The pressure on Oman has led to shifts in mediation efforts, with Muscat sensing its role was being exploited at times. As a result, other nations like Pakistan and Qatar have taken on more prominent mediation roles.

Conclusion: A Delicate Balance in a Shifting Landscape

Oman's traditional role as a neutral mediator between the United States and Iran has been severely tested by the heightened tensions and direct confrontations of recent times. Its strategic location on the Strait of Hormuz, coupled with its long-standing diplomatic ties to both opposing powers, places it in an unenviable position. While Muscat continues to advocate for dialogue and de-escalation, its ability to maintain its unique diplomatic posture and shield itself from the repercussions of regional conflicts remains a critical challenge. The delicate balance Oman strives to maintain is not merely a foreign policy choice but a necessity for its own security and economic stability in an increasingly unpredictable Middle East.
