Hormuz's New Gatekeepers: Who Actually Controls the World's Most Critical Oil Chokepoint
The same week that Donald Trump declared the United States holds "total control" of the Strait of Hormuz and promised to "retrieve uranium" from Iran, Reuters reported that Tehran was simultaneously installing checkpoints, negotiating fee structures with Oman, and embedding diplomatic agreements along the waterway's contested edges. Both narratives cannot be fully accurate. Both are partly true. The gap between them is where the actual story lives.
For decades, the narrow 34-kilometer strait connecting the Persian Gulf to the Gulf of Oman has functioned as the world's most consequential maritime chokepoint. Roughly one-fifth of global oil trade passes through its waters annually. Any disruption sends immediate shocks through energy markets. That concentration of strategic value has always attracted competing claims of authority. What is new in 2026 is the layered nature of those claims and the speed at which Iran is translating diplomatic groundwork into operational infrastructure.
A senior Iranian official, speaking to Reuters on 21 May 2026, stated that while negotiations with the United States have narrowed the gaps between both sides, no deal has yet been concluded. The statement, delivered through Tehran's preferred diplomatic channel, simultaneously signals willingness to talk and reinforces that Iranian leverage — including control over enrichment programmes and physical control of Hormuz's northern approaches — remains intact. It is a negotiating posture calibrated to both audiences: Washington, which wants a deal, and the domestic Iranian constituency for whom concessions on enrichment are politically untenable.
The question of who controls the Strait of Hormuz has never had a simple answer. Legally, it is an international waterway subject to the United Nations Convention on the Law of the Sea, which guarantees transit passage. Operationally, it has long been dominated by the United States Fifth Fleet based in Bahrain — the de facto maritime authority for the Gulf's open waters. But legal status and operational reality have always diverged in this corridor, where Iranian Revolutionary Guard naval assets operate in shallow coastal waters that US warships cannot enter without significant risk, and where the geography itself rewards whoever controls the land on either side.
What the reporting from May 2026 reveals is a deliberate Iranian project to close that gap. According to Reuters, Iran is establishing physical checkpoints, signing bilateral agreements with littoral states, and in some cases imposing what amounts to tolls on vessels transiting through contested segments. The mechanism that makes this possible is Oman. Iran and Oman are currently discussing a permanent toll arrangement for the Strait, as reported by independent market observers tracking the negotiations. Oman, which controls the strait's southern bank alongside Iran on the northern side, has historically maintained a studied neutrality that allows it to serve as a mediating interlocutor. That mediation role is now being converted into shared infrastructure.
The arrangement under discussion resembles a concession more than a traditional fee. Iran provides the northern checkpoint authority and the enforcement capacity. Oman provides the southern legitimacy and the diplomatic cover that makes the arrangement harder to characterise as piracy. Both states benefit: Oman gains a revenue stream and increased regional relevance; Iran gains a quasi-legal mechanism for asserting influence without the open confrontation that would trigger a US military response. It is a creative interpretation of international maritime law — one that a US naval commander would struggle to challenge without escalating to kinetic action.
Trump's counter-claim of "total control" is political rhetoric operating in a different register. It signals to a domestic audience that American power remains supreme in the Gulf and that Iranian posturing is theatre. It is also, by any operational measure, inaccurate. The United States Navy cannot physically prevent Iran from installing checkpoints in its own territorial waters or from negotiating with Oman on the southern bank. What the Fifth Fleet can do is ensure freedom of navigation in international waters — a different and narrower mandate than "total control." The gap between those two conditions is exactly where Iranian strategy is operating.
The uranium dimension complicates the picture further. Trump stated his intention to "retrieve uranium" from Iran, language that implies either seized material or a forcible acquisition. No such stockpile exists in a form that could simply be collected. Iran's enrichment programme operates inside hardened facilities, and its holdings of enriched material are subject to International Atomic Energy Agency monitoring — monitoring that Iran has at various points restricted. The statement reads less like a policy plan than a negotiating position: raising the cost of non-compliance by implying military options. Whether it is credible depends on whether one believes the administration has the appetite for a strike that would close the strait entirely — an outcome that would send oil prices above $200 per barrel and trigger global economic disruption.
The counter-argument to the Iranian consolidation narrative is real: the Islamic Republic's economy remains under severe pressure from sanctions, its navy is outmatched by US naval forces in open water, and its checkpoint infrastructure is vulnerable to precision strikes. Iran's leverage is real but fragile. It depends on escalation risk — the demonstrated willingness to mine the strait, to harass commercial vessels, to threaten closure — rather than on durable superiority. Every provocation carries the risk of the very US military action that Tehran's negotiators are trying to forestall.
What the May 2026 reporting reveals is a more sophisticated Iranian posture than simple threat-making. Tehran is building the infrastructure of control while leaving itself deniable space to step back. The Oman partnership is the key to this. By embedding itself in a bilateral toll arrangement with a US-aligned sultanate, Iran transforms what would otherwise be maritime intimidation into a negotiated arrangement with a legitimate co-signatory. The arrangement may be illegal under UNCLOS — the right of transit passage should not be subject to tolls imposed by coastal states — but the legal question matters less than the political question of whether any government has the will to challenge it by force.
The stakes are asymmetric. If Iran succeeds in consolidating its checkpoint regime, it gains a permanent leverage tool over Gulf oil flows without firing a shot. The toll becomes a negotiating chip that can be raised or waived depending on diplomatic circumstances — a revenue stream, a political signal, and a deterrent in one instrument. If the United States successfully challenges the arrangement, it reasserts the primacy of freedom-of-navigation norms but risks the very disruption it is trying to prevent. The safest outcome for global energy markets — a negotiated arrangement in which both Iran and the US accept operational limitations while saving face — is also the hardest to achieve, because it requires both sides to publicly accept a situation that each has political incentives to characterise as victory for the other.
What remains genuinely uncertain is whether the Oman-Iran toll discussions represent a concluded agreement or a negotiating position. Neither the timing of any permanent arrangement nor its precise terms have been reported with confidence. The IAEA monitoring situation adds a further unknown: if Iran restricts inspector access as part of a broader escalation, the uranium retrieval language becomes something other than rhetorical threat. The sources reviewed for this article do not establish whether the discussions have reached binding commitment stage, and the senior Iranian official's statement that gaps remain narrows — but does not eliminate — the space for a deal.
The Strait of Hormuz has survived decades of geopolitical pressure without being closed. Iran's current project is not closure but control — a more durable objective, and one that is harder to challenge without crossing the threshold of outright conflict. Whether Washington's "total control" framing is bluster or preparation, it will be tested against a set of facts on the water that are not moving in the direction the White House rhetoric suggests. The strait's gatekeepers are being reshuffled, and the new arrangement may be harder to dismantle than the previous one.
Desk note: This publication's reporting on the Strait of Hormuz draws primarily from Reuters wire reports and the Indian Express account of the President's statements. Where our framing diverges from the US government line — characterising Iran's consolidation activities as a diplomatic-infrastructure project rather than merely provocative harassment — the divergence reflects the available evidence about what Iran is actually building, not advocacy for any party's position.
