The Toll Booth at the End of the World

Iran, Oman, and the Battle for the Strait of Hormuz

Published May 22, 2026

The Strait of Hormuz is twelve miles wide at its narrowest point. Through it flows roughly one fifth of all the oil that moves by sea in the world — approximately 135 ships per day before the war, carrying the energy that heats homes, runs factories, and fuels militaries from Europe to Asia. Whoever controls that twelve-mile passage controls a lever of the global economy that no amount of financial engineering can fully replace. Iran has spent the last three months making clear it understands this. Today, it is moving to make that control permanent.

Iran confirmed this week that it has collected its first toll payment from ships transiting the Strait of Hormuz, and is now in active discussions with Oman to establish a formal, permanent toll system that would institutionalize its authority over one of the world's most critical maritime chokepoints. Iran's ambassador to France told Bloomberg that "those who wish to benefit from this traffic must also pay their share," adding that the system will be transparent. The structure Iran's National Security Committee has already approved charges oil tankers approximately $1 per barrel, with payment required in yuan or stablecoins — explicitly bypassing the U.S. dollar.

To understand why this matters, you have to go back to February 28, when the United States and Israel launched their air campaign against Iran and assassinated Supreme Leader Ali Khamenei. In retaliation, Iran largely shut the strait down. The Iranian Revolutionary Guard issued warnings forbidding passage, boarded and attacked merchant ships, and laid sea mines in the waterway. At least 17 merchant ships have been damaged, seven abandoned, two captured, and twelve seafarers killed or missing. A tugboat was sunk. The global fuel crisis that followed has reverberated through energy markets, insurance rates, and supply chains across every continent.

Since April, the United States has maintained a naval blockade of Iranian ports, and a fragile ceasefire has done little to restore normal shipping. Iran claims — without providing evidence — that 26 tankers transited the strait in a recent 24-hour period with IRGC assistance. That number, even if accurate, is a fraction of pre-war levels. Most shipping companies say they will not send vessels through until the threat of missile attacks, drone strikes, and sea mines is resolved. Insurance costs for vessels willing to attempt the passage have become prohibitive.

Iran's position on reopening is unambiguous: it will not do so until the United States lifts its naval blockade of Iranian ports. Trump's position is equally unambiguous: the strait should be open, free, and toll-free. The gap between those two positions is where the global economy currently sits.

Into that gap steps Oman, playing the diplomatic role it has quietly occupied for decades. No other Gulf state maintains the kind of dual relationship with both Tehran and Washington that Muscat does — it was Oman that served as the secret back-channel for the original Iran nuclear deal negotiations under Obama, and it hosts U.S. military facilities while simultaneously sitting across the table from Iranian deputy foreign ministers. The talks between Oman and Iran have now reached the level of formalizing not just a ceasefire arrangement but a permanent maritime governance structure, with Iranian parliamentary committees already voting to impose tolls and ban U.S. and Israeli vessels from the strait entirely.

The yuan and stablecoin payment requirement is the most consequential detail in the entire arrangement, and it is not accidental. Requiring payment in a currency other than the dollar for passage through one of the world's most critical energy chokepoints is a direct challenge to dollar dominance in global energy markets — a pillar of American financial power in place since the 1970s. China, which has pursued for years the goal of denominating more global trade in yuan, benefits from this arrangement whether or not it had any hand in designing it. Every tanker that pays Iran in yuan for passage through the strait is a small but concrete step toward a world in which the dollar's role as the universal currency of energy trade is no longer guaranteed.

During the brief ceasefire in April, Iran and Oman jointly imposed tolls on ships transiting the strait, with Iran directing the funds toward reconstruction — establishing the precedent and the infrastructure before any peace deal was reached. That sequencing is deliberate. Iran is not waiting for a negotiated settlement to establish facts on the water. A permanent toll system administered with Oman, paid in non-dollar currencies, would transform a temporary wartime disruption into a permanent revenue stream and a durable instrument of geopolitical leverage. By the time any agreement is reached, the architecture of control may already be too embedded to dismantle.

This is a different kind of victory than winning the war. Wars end. Toll booths, once built, tend to stay.
