Trump Says Hormuz Will Stay Open as Iran Bars 'Hostile' Vessels
President Trump told reporters at the White House on 27 May 2026 that the Strait of Hormuz would be open to all traffic, pushing back against any arrangement that would grant Iran and Oman joint control over the world's most critical oil chokepoint. His remarks, delivered during a cabinet meeting, came hours after Iran's Islamic Revolutionary Guard Corps Navy announced it would bar vessels from "hostile countries" from transiting the strait. The duelling assertions sent oil prices to one-month lows while lifting US equities to fresh records and knocking bitcoin below the $75,000 mark.
The competing narratives over a waterway through which roughly a fifth of global oil shipments pass expose the fragility beneath the headline optimism of ongoing US-Iran nuclear talks. Markets priced for a breakthrough; the reality on the water suggests the negotiating teams face more fundamental disagreements than a deal sheet would indicate.
A Deal Premium, Then a Reality Check
Bitcoin fell below $75,000 on 27 May as traders reassessed the probability of a quick US-Iran agreement, CoinTelegraph reported. The cryptocurrency had rallied in anticipation of sanctions relief that would reintegrate Iranian crude into global markets and ease geopolitical risk premiums across energy commodities. US stocks, meanwhile, touched new all-time highs on the same Hormuz de-escalation hopes, reflecting investor confidence that a diplomatic resolution would remove a key source of energy price volatility.
Oil markets told a more cautionary story. Prices shed roughly three percent intraday to settle at one-month lows, a move that typically signals reduced risk rather than resolved risk. The Strait of Hormuz handles approximately 21 million barrels of oil per day, according to industry reference estimates. Any credible threat to that flow — or even sustained ambiguity about access — translates directly into a risk premium embedded in every tanker rate and refinery contract.
The Polymarket market on Iran surrendering its enriched uranium stockpile placed the probability of a deal by the end of June at 33 percent as of the morning of 27 May, a reading that suggests genuine uncertainty rather than the near-certainty that was briefly priced into markets earlier this month.
What Iran's IRGC Navy Actually Said
The IRGC Navy's statement on 27 May that vessels from "hostile countries" would be barred from Hormuz requires careful reading. The announcement did not constitute a blockade or an act of force — it articulated a political position about which flag-states the Islamic Republic would recognise as legitimate actors in waters Tehran considers within its sphere of influence.
Western naval assessments have long maintained that the IRGC Navy lacks the conventional surface fleet to enforce a choke-hold on the strait comparable to wartime scenarios. Its capabilities are asymmetric: small boats, mines, anti-ship missiles, and drones optimised for denial rather than control. A blanket exclusion of "hostile" vessels is, in operational terms, a messaging exercise as much as a force posture. The statement's timing, however — concurrent with the cabinet-meeting exchange in Washington — suggests it was calibrated to reach the same audience watching the same news cycle.
The Omani Angle
Neither Washington nor Tehran appears to have formally consulted Muscat on any joint-control arrangement, despite the question being put to President Trump at the cabinet meeting. Oman has historically occupied a mediating position in Gulf security architecture, maintaining working relationships with both the United States — which hosts a significant naval presence at its Duqm port — and Iran, with which it shares a maritime border. The Sultanate has neither the capacity nor, by all available signals, the intention to serve as a co-enforcer of Hormuz access rules.
Trump's answer — "it's going to be open to everybody" and "nobody" will control it — reflects the legal and diplomatic baseline the US has maintained since the 1980s tanker-escort era. It is also a statement of intent rather than a description of current capability. The gap between those two things is precisely where the negotiating teams must find agreement before any formal framework can claim to settle the question.
Energy Markets and the Forward View
If a nuclear deal does materialise — whether by end of June or later — the most immediate consequence would be the phased removal of sanctions that currently restrict Iran's oil exports. The International Energy Agency has previously estimated Iranian crude output could return to pre-2018 levels of roughly 3.8 million barrels per day within twelve to eighteen months of credible sanctions relief. That volume, hitting a market already dealing with OPEC+ production discipline and uncertain demand trajectories, would represent a structural rather than cyclical shift in the global oil balance.
For Asian refiners — particularly in China, India, and South Korea — the prospect of restored Iranian supply would complicate existing relationships with Gulf Arab producers and, in the case of China, introduce additional complexity into the already intricate web of US secondary sanctions enforcement. The EU would regain a significant gas supplier via Iranian condensate exports, easing the pressure on spot LNG markets that have been volatile since the Russia-Ukraine disruption.
The bitcoin move on 27 May underscores how thoroughly digital asset markets have become tethered to traditional geopolitical risk. A chokepoint dispute that would historically have moved only gold and oil futures now reaches into every leveraged crypto position held overnight. That contagion reflects the broader financialisaton of energy geopolitics, and it means the stakes of a Hormuz misunderstanding extend well beyond tanker rates.
What remains uncertain is whether the gap between Washington's "open to everybody" and Tehran's "hostile countries excluded" represents negotiating room or irreconcilable positions. The Polymarket odds suggest markets think a deal is still more likely than not — but the gap between 33 percent and certainty is wide enough to drive significant price volatility in both directions.
