US Warns Oman Against Strait of Hormuz Tolls Amid Iran Tensions

The United States, on May 28, 2026, issued a clear and forceful warning to Oman, cautioning the Gulf nation against any direct or indirect involvement in establishing a tolling system in the strategically vital Strait of Hormuz. U.S. Treasury Secretary Scott Bessent publicly stated that Washington would 'aggressively target' any actors facilitating such tolls, signaling a firm stance against any attempts to disrupt the free flow of commerce through the waterway. This warning from Secretary Bessent underscored the U.S. government's resolve, asserting that it would 'not tolerate any effort to impose a tolling system in the Strait of Hormuz' and that 'any willing partners will be penalized'. The development comes amidst escalating tensions in the Middle East, particularly concerning Iran's intentions regarding the Strait of Hormuz. The Strait, a narrow maritime chokepoint between the Persian Gulf and the Gulf of Oman, is globally recognized as a critical artery for international oil and gas shipments, with nearly a fifth of the world's oil trade passing through it. The possibility of tolls or new management structures in this waterway has significant implications for global energy markets and economic stability. Adding to the gravity of the situation, the U.S. warning followed earlier, more direct threats from President Donald Trump. On May 27, 2026, President Trump reportedly threatened to 'blow up' Oman if it cooperated with Iran in any arrangement to jointly control the Strait of Hormuz. This aggressive rhetoric from the U.S. President further amplified the diplomatic pressure on Oman, a long-standing U.S. ally that has historically played a mediating role in regional disputes, including those involving Washington and Tehran. The White House, however, did not immediately clarify if President Trump had intended his threat to be directed at Iran rather than Oman. Iranian state media had previously claimed that a draft proposal was under discussion between Tehran and Muscat for joint management of maritime traffic and potential revenue sharing from the Strait of Hormuz. Iran's foreign ministry spokesperson, Esmaeil Baghaei, condemned President Trump's threats, describing them as 'another dangerous sign of the normalisation of lawlessness and bullying in international relations'. This proposal, if implemented, would have involved a system where ships would enter the Persian Gulf via an Iranian-controlled route and exit through an Omani-controlled route, with the collection of transit or service fees being a contentious point. However, in a significant follow-up development reported on September 4, 2026, Oman reportedly rejected the Iranian proposal to impose fees on commercial vessels using the Strait of Hormuz. A senior regional official, cited by the New York Post, indicated that Oman had declined to approve the proposed charges, including those for environmental and security services. This rejection by Oman appears to contradict earlier claims by Iran's Islamic Revolutionary Guard Corps (IRGC) that an agreement had been reached on revenue sharing from the strategic waterway. Oman's decision helps it avert a direct confrontation with the U.S. and align with international pressure against such tolls. The legal justification for imposing such fees is a complex issue. While international law grants ships the right of 'innocent passage' through territorial waters, making simple transit tolls illegal, some analyses suggest that charging fees for specific navigational and security services might be permissible. JPMorgan, a U.S. investment bank, even suggested in a memo that Iran and Oman's strategy of imposing mandatory 'navigational safety' fees could be legally justified, citing precedents where countries like Denmark, Sweden, and Turkiye charge for services in their narrow straits. These fees are typically for services like mandatory pilotage for vessels carrying hazardous cargo. However, the U.S. maintains that any such system would be a 'mafia protection scheme' and has shown no tolerance for it. Geopolitical tensions around the Strait have been heightened by a broader conflict between Iran and the U.S. in early 2026, which saw the U.S. enforcing a blockade on Iranian ports and accusations of Iran laying mines and attacking tankers in the waterway. These actions led to a near halt in shipping and a surge in global energy prices. U.S. officials, despite imposing fresh sanctions on Iran's financial networks, have also indicated progress towards a deal with Tehran over the Strait of Hormuz, with talks focusing on restoring commercial shipping without impediments. The potential for a ceasefire agreement and reopening of the Strait has been linked to hopes of bringing down energy prices. For India, a major importer of crude oil, the stability of shipping through the Strait of Hormuz is paramount. Any disruption, increased transit fees, or heightened security risks in the waterway directly impact India's energy security and can lead to significant economic ramifications through higher oil prices. Therefore, developments concerning the Strait are of critical importance to India and the global economy.
