Oman's voluntary fee plan for Hormuz risks 3-way standoff
Oman has proposed a voluntary service fee model for ships transiting the Strait of Hormuz, breaking with Iran's demand for mandatory tolls and setting up a three-way dispute with Washington as US envoys arrived in Doha for nuclear talks.
"Fees and tolls are the same thing to me. There isn't a nation on Earth that supports having to pay money to go through the Strait," Secretary of State Marco Rubio said, underscoring US opposition to any payment regime.
Iran insists every vessel passing through must pay transit fees, while Oman's counterproposal — modeled on the Malacca Strait's voluntary mechanism — would let ships that decline to pay continue unimpeded, according to two Western diplomats. The Strait handles about 21 percent of global oil trade, or roughly 17 million barrels per day, making any disruption a direct threat to energy markets.
If Oman and Iran fail to agree on a joint governance framework within Tehran's 60-day negotiation window, Iran has threatened to implement its own toll plan independently — a move that could trigger military escalation, spike crude prices, and redraw the insurance and shipping economics for every tanker crossing the Gulf.
Iranian Deputy Foreign Minister Kazem Gharibabadi warned Monday that if Muscat declines to establish a joint framework under the Islamabad Memorandum of Understanding, "the Islamic Republic will proceed with implementing its own plan independently." The warning followed the inaugural meeting of the Iran-Oman joint committee on Strait management.
The dispute has already drawn military responses. The Islamic Revolutionary Guard Corps deployed naval assets to the area last week and launched at least six drones per day in recent days, a source familiar with the matter said. Two vessels were reportedly struck, prompting the US military to carry out strikes against Iranian military targets along the Strait.
A precedent from Malacca
Oman's voluntary fee structure mirrors the Malacca Strait's Ship Traffic Separation Scheme, where vessels contribute to navigational safety and environmental protection on a non-mandatory basis. That model has operated for decades without escalating into a sovereignty dispute. But the Strait of Hormuz differs in one critical respect: Iran controls the northern coastline and has repeatedly threatened to close the waterway during past confrontations with the West.
The last time Iran directly challenged freedom of navigation in the Strait was in 2019, when it seized tankers and attacked Saudi Aramco facilities. Brent crude spiked 15 percent in the week following those incidents, and war risk insurance premiums for Gulf transits jumped fivefold.
What happens next
Trump envoys Jared Kushner and Steve Witkoff arrived in Doha on Tuesday for talks with Qatari mediators. US and Iranian technical teams are expected to meet separately with Qatari and Pakistani mediators on Wednesday to discuss both the Strait's governance and Iran's nuclear program. The 60-day negotiation period gives all parties until late August to reach a framework — or risk a unilateral Iranian implementation that could push Brent above $100 a barrel, according to analysts tracking the region.
