Tankers are moving through the strategic waterway, but every passage still depends on risk, coordination and fragile diplomacy.
Muscat, June 2026
Commercial vessels continue crossing the Strait of Hormuz despite renewed Iranian warnings and a recent attack that again exposed the vulnerability of one of the world’s most important maritime routes. Tankers carrying crude oil, Iranian exports and other strategic cargoes entered or left the Persian Gulf on Friday, although overall traffic remained well below normal levels.
Ship-tracking data showed that at least four tankers entered the Gulf to load oil, including three very large crude carriers capable of transporting up to two million barrels each. Two additional supertankers reportedly entered the strait to collect Iranian crude, while another vessel exited through waters near Oman carrying approximately two million barrels.
The movements demonstrate that shipping has not stopped, even as companies, captains and insurers continue evaluating the danger of each transit. The strait remains economically indispensable, and buyers seeking supplies after months of disruption have strong incentives to accept risks that would normally be considered unacceptable.
Traffic nevertheless slowed after a Taiwanese-operated vessel was attacked near the Omani side of the waterway. The incident damaged the ship and forced maritime authorities to reassess temporary transit arrangements intended to help vessels trapped inside the Gulf. The United Nations shipping agency subsequently suspended a voluntary evacuation program until stronger safety guarantees could be obtained.
Iran has insisted that vessels must coordinate their passage with authorities in Tehran. Iranian officials have rejected routes developed without their authorization and warned that ships using alternative corridors may place themselves in danger. That position has intensified the dispute over who controls navigation through a strait recognized internationally as a route for global transit.
The disagreement is not merely technical. Iran is attempting to establish greater authority over movements through the waterway after months of conflict and maritime disruption. The United States and several Gulf governments, by contrast, maintain that international shipping cannot depend on prior Iranian approval or politically conditioned access.
The recent attack has placed additional pressure on a fragile understanding between Washington and Tehran. A ceasefire arrangement had raised expectations that normal shipping could gradually resume, but the incident demonstrated that the military and political conditions surrounding the strait remain unsettled.
Iranian forces have warned that safe transit requires coordination, while the United States has reaffirmed its commitment to freedom of navigation. Between those positions are hundreds of commercial vessels whose operators must decide whether political assurances are reliable enough to justify entering a narrow and heavily monitored passage.
Traffic figures reflect that uncertainty. Tanker crossings fell to 13 on Friday after reaching 24 on Thursday and 27 on Wednesday. Total ship movements earlier in the week were approximately half the level recorded during the same period a year earlier, indicating that activity is continuing without approaching a full return to normal.
Before the crisis, the Strait of Hormuz handled a substantial share of the world’s seaborne oil and liquefied natural gas. Its narrow geography connects producers including Saudi Arabia, the United Arab Emirates, Kuwait, Qatar, Iraq and Iran with international markets. Few practical alternatives can replace the route at comparable scale.
That dependence explains why vessels continue moving despite the warnings. Oil buyers are attempting to rebuild inventories after months of interrupted trade, while exporters need to restore revenue and clear accumulated cargoes. Every successful transit increases confidence, but every attack can reverse that progress immediately.
The movement of Iranian oil adds another layer of complexity. Iran retains an interest in demonstrating that it can protect or authorize shipments connected to its own economy while influencing the conditions faced by other vessels. This creates an environment in which passage may appear selective rather than universally secure.
Insurance remains one of the principal barriers to normalization. Shipowners may be willing to navigate the strait, but coverage for war, damage and crew risk has become more expensive and difficult to obtain. A single attack can increase premiums, lead underwriters to suspend coverage or force operators to renegotiate contracts.
Captains also retain responsibility for the safety of crews. Even when companies approve a transit, commanders must consider intelligence reports, naval activity, mines, drones and the reliability of proposed routes. The final decision is therefore shaped by commercial necessity and personal responsibility at the same time.
The temporary suspension of the United Nations-supported evacuation program illustrates the limits of international coordination. The initiative was designed to help stranded ships and thousands of seafarers leave the Gulf through designated corridors. Its interruption leaves many vessels facing longer waits and uncertain departure schedules.
Fertilizer shipments have also begun moving through Hormuz again, offering some relief to agricultural markets. The strait previously carried large volumes of urea and sulphur used in fertilizer production, and prolonged disruption raised fears of higher costs for farmers and food producers.
Recent shipments indicate a partial recovery, but analysts caution that much of the activity involves delayed contracts rather than a complete return of new commercial business. Companies remain reluctant to commit vessels when security conditions can change within hours.
Oil markets have reacted with similar uncertainty. Crude prices declined as tanker movements resumed and fears of immediate shortages eased, but traders remain aware that another serious incident could produce a rapid reversal. The market is no longer responding only to supply figures; it is interpreting military signals, diplomatic statements and ship-tracking data almost simultaneously.
Saudi Arabia and other Gulf producers have resumed some loadings, strengthening expectations that exports can gradually increase. Yet the region’s energy infrastructure and maritime routes remain vulnerable after months of conflict. Restoring production is easier than restoring confidence.
The United Arab Emirates has urged Iran to protect maritime security and guarantee the free flow of traffic. The diplomatic message reflects a broader Gulf concern that continued instability could damage trade, investment and the reputation of regional hubs as secure places for business.
For Iran, control over Hormuz remains an instrument of strategic leverage. The ability to threaten, delay or condition passage gives Tehran influence far beyond its conventional military and economic weight. It also creates the risk that tactical actions could trigger wider confrontation.
The current traffic therefore should not be confused with normalization. Ships are moving, but at reduced levels and under exceptional conditions. Routes are being adjusted, crews are operating under heightened alert and every transit is treated as an individual security calculation.
A durable reopening would require more than a decline in attacks. Shipping companies need clear rules, stable insurance coverage, credible guarantees and confidence that political disputes will not suddenly become military operations at sea.
The Strait of Hormuz remains open enough for trade to continue but dangerous enough to influence every decision surrounding it. Its traffic is proof of economic necessity, not evidence that the crisis has ended.
El comercio puede desafiar al miedo, pero no puede navegar indefinidamente sin confianza. / Trade can defy fear, but it cannot sail indefinitely without trust.
