Commercial shipping through the Strait of Hormuz has stabilized following the US-Iran memorandum of understanding signed last month, British maritime authorities reported on Monday, but traffic volumes remain well below pre-war levels and the pace of recovery shows little sign of accelerating given persistent security threats that continue to warrant heightened vigilance.
The United Kingdom Maritime Trade Operations center, operated by the British Royal Navy, described vessel movements through the strait in a July 5 update as steady in recent days, with commercial ships continuing to use both the southern shipping corridor through Omani waters and the northern route that passes through Iran-controlled waters. The assessment characterized current risk as lower than during the period before the memorandum was signed while stopping well short of declaring the environment normalized.
Stranded vessels finally clear the strait
The update came alongside the reported exit of a fleet of ten Japan-linked commercial vessels, including six very large crude carriers loaded with approximately 12 million barrels of Middle Eastern crude oil, that had been stranded in the Persian Gulf for months during the height of the Iran conflict when the strait was effectively closed to commercial traffic.
The departure of those vessels, carrying a significant combined cargo of crude, represents one of the more concrete signs that the memorandum has produced tangible results for the shipping industry, while also illustrating the scale of the backlog that built up during the period of disruption. Twelve million barrels of crude held in place for months represents a substantial commercial and logistical cost that accumulated across the industry while the strait remained inaccessible.
What the British assessment actually says
The language used by the maritime authority in its July 5 update is carefully calibrated and avoids any suggestion that normal conditions have returned. The center noted the absence of a sustained increase in traffic along the US-supported southern corridor, which would be the clearest signal that the shipping rebound was gaining momentum. Without that acceleration, the current stability represents a floor rather than a recovery trajectory.
More significantly, the center flagged three ongoing threat factors. Navigation interference in the waterway continues to be reported, meaning electronic or physical disruption to vessel guidance systems remains an active concern. The threat from naval mines laid by Iranian forces during the conflict was described as still relevant, implying that mine clearance has not been completed to the point where the risk can be considered resolved. And Iranian military capability and intent to conduct hostile action were characterized as persisting despite the absence of recent escalation.
The gap between stability and normalization
The overall threat level for the strait was labeled substantial, a designation that sits several steps below the kind of assessment that would indicate a return to routine commercial operations. Shipping companies, insurers, and charterers operating in the region are likely to continue applying war risk premiums and requiring specific routing protocols until the threat assessment improves materially.
The 60-day negotiating window established by the memorandum is still active, with technical discussions between the parties continuing in Doha aimed at producing a permanent agreement. The maritime situation will track closely with developments in those negotiations, since any deterioration in the diplomatic process would immediately raise the prospect of further disruption to shipping in a waterway through which a significant share of global energy supplies must pass.
For now, ships are moving and the strait is technically open. Whether that status holds and whether volumes return to pre-war levels depends on whether the peace process produces durable results over the weeks ahead.
