The crisis in the Persian Gulf, why the U.S. Navy is still unable to escort oil tankers

A convoy of tankers anchored off Dubai, engines idling and navigation lights on to avoid disappearing into the Gulf's haze: this is the image that, in recent hours, best illustrates the fragility of global energy security better than any press conference. The Strait of Hormuz, the valve through which about 20% of the world's oil passes, has become a funnel. On the docks, the families of seafarers await news, shipowners are grappling with "crazy" insurance rates, and in Washington, every word is measured. After a post that was later deleted, Secretary of Energy Chris Wright clarified: the United States "is not yet ready" to escort tankers through the bottleneck between Iran and Oman; the priority, he explained, remains "to destroy Tehran's offensive capabilities." No theatrical moves, then. For naval supplies, the talk is — at best — of late March or early April. In the meantime, the route remains uncertain.

A necessary clarification after hours of confusion

On Tuesday, March 10, 2026, a social media message from Wright's office suggested that a first escort of a tanker had already occurred "successfully" in the Strait of Hormuz. The White House, a few hours later, denied this: "The US Navy has not escorted any ships at this time," said spokesperson Karoline Leavitt, urging everyone to exercise caution on a day already marked by significant fluctuations in crude oil prices. The Department of Energy later stated that the post was "improperly labeled" and that any escorts remain "an option," not a fact.

The clarification comes amid a rapidly evolving operational context: within the same 48 hours, US Central Command (CENTCOM) announced that it had neutralized 16 Iranian units intended for mine laying, while analysts and industry sources report that commercial traffic is "almost zeroed out" in the planet's most sensitive maritime corridor. Mines are the "low-cost, high-impact" weapon that makes the Strait a treacherous labyrinth: just a few devices are enough to halt hundreds of thousands of barrels.

Why supplies are not leaving immediately

Behind the "not yet" lies a risk assessment that intertwines geography, tactics, and politics. The Strait of Hormuz is a narrow waterway, flanked by Iranian shores dense with anti-ship missiles, drones, and coastal batteries, where the use of mines and explosive boats can turn tankers and escort ships into slow and predictable targets. It is not the Red Sea, where the experience gained in countering Houthi missiles and drones has allowed for the protection of convoys in wider waters: here the margin for error is minimal and the saturation of threats much higher. Former naval commanders and analysts warn: attempting a protected corridor without adequate "clearing" of the theater would be "very, very dangerous."

To this is added the political-strategic component: according to Wright, the American operational priority today is to "destroy Iran's offensive capabilities and the industry that supports them." Translated: strike missile launchers, drones, logistics, and shipyards that enable Tehran to threaten shipping. As long as this pressure does not reduce the density of fire possible from the Iranian shore, inserting destroyers and frigates alongside commercial vessels would risk concentrating valuable forces in a single point, exposing them to salvos of missiles and barrages of mines.

Timing: the "late March, early April" window

On the organizational front, an analysis circulated among operators and marine insurers indicates that the establishment of a true naval protection system will take time. The most cautious estimate suggests waiting at least until the end of March or even the beginning of April to see structured supplies, with clear rules of engagement, transit corridors, and reactivated insurance coverage. In the meantime, despite political announcements, the United States has not yet initiated escort missions, and even European partners are evaluating how to integrate into a potential arrangement.

What is blocking the resumption of tankers

Multi-level threat. The Strait can be blocked with a combination of naval mines, anti-ship missiles launched from the coast and from mobile platforms, drones, and explosive boats. Even "hit-and-run" operations with fast boats are difficult to prevent in such narrow waters.

Mine clearance difficulties. Mine clearance requires specialized means, continuous air coverage, and time. As long as Iranian offensive activity persists, mine countermeasure assets operate in a "contested" environment, with high risks.

Insurance and liability. Insurance premiums have skyrocketed to "unsustainable" levels, deterring shipowners even if they are willing to take risks. Without a framework of government guarantees and a perimeter of risk sharing, flows remain constrained.

Logistics of supplies. Rules of engagement, interoperable command and control systems, supplies at sea, support bases, and — not least — the availability of warships for extended rotations are needed. It is a puzzle that cannot be solved in 24 or 48 hours.

The White House's position and the communicative "step back"

The clarification from Karoline Leavitt on March 10-11 has frozen any excessive interpretation: "At the moment, there have been no supplies," she said, while leaving the option open for the future "if and when necessary." A cautious message, consistent with the operational line. The incident of the deleted post from Chris Wright's account — described as the result of a staff error — showed how a single phrase can move markets, fuel expectations, and complicate the work of those at sea who must determine if, when, and how to restart.

What the US Navy is doing now

While the diplomatic and operational groundwork for potential supplies is being laid, the US Navy is focusing efforts on reducing risk at the source: intercepting naval threats in preparation, neutralizing minelaying assets, and intensively surveilling approaches to the Strait. According to official sources, on Tuesday, March 11, 16 Iranian boats intended for mine laying were destroyed; a move that slows but does not eliminate the possibility of ordnance drifting along the routes. In parallel, work is underway on option plans to establish protected corridors "when conditions allow."

The debate among allies: towards a broader mission?

Within the Euro-Atlantic perimeter, the idea of a support coalition is growing — following the example of what was done in the Red Sea against the attacks from the Houthis — capable of sharing burdens and responsibilities. Operational assessments are also circulating among European navies and Middle Eastern partners, with scenarios ranging from punctual escorts "at time windows" to the creation of a convoy corridor with air cover and electronic warfare. Experts, however, insist: the difference in scenario compared to the Red Sea is substantial, and any mission in the Gulf of Oman and the Strait of Hormuz would require robust informational superiority and continuous monitoring against missiles, drones, and mines.

The ships: why many remain anchored

Inertia is not just fear. It is calculation. With insurance premiums at record levels and freight rates unable, in the immediate term, to offset the risk, shipowners are suspending or postponing. According to estimates shared by industry operators, hundreds of tankers would be idle in the Gulf, waiting for a credible signal that the risk is subsiding. An announced but not yet deployed naval escort is not enough to convince those who must put assets worth tens of millions of dollars to sea with crews of 20-30 people. Protocols, transit rules, escort slots, and — above all — proof that "those who enter, exit" are needed.

The energy market and the announcement effect

Every operational update in the Strait immediately reflects on crude oil prices and derivatives. The subsequently deleted post from the Department of Energy produced a brief relief in prices, only to reverse on official clarifications. In parallel, the potential use of strategic reserves and the push to increase flows from alternative routes only partially alleviate market anxiety. The lesson of these days is clear: as long as the Strait of Hormuz does not reopen safely, every announcement is worth little if not accompanied by operational evidence — convoys departed, ships arrived — and a sustainable insurance framework.
