The State Department says the United States is using economic pressure against Iran's shadow banking, money laundering, and sanctions evasion networks. The release is part of actions targeting entities linked to Iranian financial and shipping activity.

The United States is imposing sanctions on dozens of entities and vessels involved in Iran’s ‘shadow oil’ network, which helps the regime generate billions of dollars in illicit revenue. The fact sheet details involvement of actors in the People’s Republic of China, the UAE, Hong Kong, and other locations in moving Iranian oil and concealing its origin. It does not allege that the government of Oman is participating in or facilitating sanctions evasion on Iran’s behalf.

OFAC’s Sanctions List Search tool allows users to search the Specially Designated Nationals and Blocked Persons (SDN) List and other sanctions lists for individuals, entities, or vessels. As of late May 2026, searches for terms related to the Government of Oman or Omani state institutions do not return designations tied to Iran sanctions evasion. Existing entries involving Oman relate to private companies or individuals rather than the Omani government itself.

The United States is designating a sanctions evasion network providing support to Hizballah and the Islamic Revolutionary Guard Corps-Qods Force (IRGC-QF) by facilitating the sale of Iranian oil to foreign customers, including in East Asia. The fact sheet lists individuals and companies in Iran, the UAE, and elsewhere. It does not mention the Omani government as part of this network or otherwise accuse Oman’s authorities of assisting Iran in evading sanctions.

The EU Sanctions Map lists restrictive measures imposed on Iran, including asset freezes, travel bans, and sectoral restrictions in response to Iran’s nuclear programme, human rights violations, and military support to Russia’s war against Ukraine. The country entry for Oman lists EU measures applied to Oman (if any), but the map does not describe Oman as a target of EU sanctions for assisting Iran, nor as being under EU investigation for systematically helping Iran evade sanctions.

The State Department’s bilateral relations fact sheet describes Oman as a longstanding U.S. partner that maintains diplomatic and economic ties with Iran while also cooperating with the United States on regional security and maritime issues. It notes that Oman has played a mediating role between Iran and Western countries and participates in efforts to ensure freedom of navigation in the Strait of Hormuz. The fact sheet does not state that the Omani government is involved in or supports Iranian sanctions evasion.

A May 2026 State Department fact sheet details U.S. sanctions targeting Iran’s “shadow oil economy,” including designations on shipping firms, front companies, and individuals that facilitate sanctions evasion. The document lists multiple jurisdictions where shell or front entities operate and mentions maritime routes such as the Gulf of Oman, but it does not state that the government of Oman is officially assisting Iran in evading international sanctions or that Oman itself is a sanctions target in this context.

This 2020 study for the European Parliament analyses U.S. extraterritorial sanctions, including those on Iran, and their impact on EU trade. It discusses how third-country firms and financial intermediaries may become involved in sanctions evasion, and it mentions the Gulf region as a transit point for Iranian trade. The study does not identify Oman’s government as a sanctioned party or as an officially recognized facilitator of Iranian sanctions evasion, nor does it describe EU sanctions specifically targeting Oman for such conduct.

The January 2026 sanctions and export controls report surveys global enforcement actions, including EU and U.S. measures on Russia and Iran. It describes investigations into complex shipping and ownership schemes in regions such as the Gulf and Indian Ocean. The report does not describe any EU decision to sanction Oman for helping Iran evade sanctions, nor does it cite an EU investigation directly accusing the Omani government of facilitating Iranian sanctions evasion.

Washington describes this network as instrumental in transporting Iranian oil to China, circumventing sanctions, and financing entities connected to Iran. The report says firms in Oman were among those sanctioned in the action.

Iran International reports that "a small port on Oman’s Musandam Peninsula has become part of Iran’s workaround to the maritime blockade in the Strait of Hormuz, traders say." The article describes how, with main passages in the Strait closed to Iranian ships, "Khasab has shifted from a local secondary route into one of several alternatives for moving goods into Iran," where cargo is carried from UAE ports to Khasab on vessels with non-Iranian flags and then transshipped onto Iranian vessels. It notes that traders and social media accounts "present the route as proof that imports into Iran are continuing despite the war and maritime restrictions" but does not document explicit, official involvement by the Omani government in sanction evasion, instead focusing on commercial and logistical practices at the port.

U.S. Treasury Secretary Scott Bessent warned Oman of sanctions if it supports any Iran-linked tolling system in the Strait of Hormuz. The article quotes Bessent saying the Treasury would aggressively target actors involved, directly or indirectly, in facilitating tolls.

The report says Iran has held talks with Oman about charging fees for services provided to vessels passing through the Strait of Hormuz. It also says Oman initially dismissed the idea but later saw potential benefit, according to the New York Times' reporting cited in the article.

Oman has long maintained pragmatic economic and diplomatic ties with Iran and has often served as a mediator, but that relationship is not itself proof of sanctions evasion. In fact, when claims involve sanctions-busting, the strongest evidence usually comes from named U.S. designations, court records, or shipping/finance tracing rather than diplomatic reporting alone.
