Gulf shipping surge masks deepening Iran-US control dispute over Hormuz strait

Vessel traffic through a US-backed southern corridor has surged roughly 400 percent over the past two weeks, reaching nearly 200 ships per week, even as Iran insists it controls the Strait of Hormuz. That operational contradiction sits at the heart of a rapidly shifting landscape across the Gulf, where the Washington-Tehran standoff is now directly disrupting commerce, aviation and daily life in the Emirates.

The UAE moved swiftly on the trade front, suspending all commercial activities, trade exchanges and financial transactions with Iran, effectively halting a major regional corridor. Air defence systems remain on high alert across the Emirates, positioned to intercept threats entering territorial airspace or waters. Residents are advised to follow official civil defence guidance and disregard unverified security rumours.

Aviation services reflect the disruption in granular detail. Emirates cancelled two Dubai-Bahrain flights, EK835 and EK837, while EK839 was scheduled to operate as planned. Dubai-Kuwait services were scheduled to continue. Etihad’s Abu Dhabi-Bahrain and Abu Dhabi-Kuwait routes were largely operating, though flydubai reported cancellations on some schedules, including flight FZ8504 to Bahrain, while maintaining services to Kuwait, Saudi Arabia and Bahrain on other departures. Air Arabia also reported cancellations and pending departures on select UAE-Kuwait-Bahrain routes. Passengers should verify status directly with their carrier before heading to the airport.

The maritime picture is more severe. Iran has declared it will keep the Strait of Hormuz closed until the US lifts sanctions and its naval blockade, complicating commercial navigation through one of the world’s most critical oil-shipping routes. US Central Command has redirected 70 vessels amid the blockade, disabled three and boarded two, citing compliance requirements. The surge in southern-corridor traffic signals a weakening grip by Tehran over global energy flows, whatever the official Iranian position.

Meanwhile, Washington is expected to announce additional sanctions on Monday. US Treasury Secretary Scott Bessent has characterised the planned measures as the “toughest sanctions in history.” Those measures compound existing economic pressure on Iran, where the currency has collapsed to historic lows. The dollar crossed 200,000 tomans (equivalent to 2 million rials) in Iran’s open market, intensifying pressure on import costs, inflation and household purchasing power.

Iran’s newly appointed national security adviser, Mohsen Rezaie, has warned Gulf neighbours that continuing participation in US sanctions will be treated as “an act of war,” threatening that no oil will be exported through the Strait of Hormuz or anywhere in the Gulf if economic pressures persist. The Iran Gulf Strait Authority issued new maritime protocol restrictions targeting shipping traffic. Vessels violating Iranian protocols or interacting with blacklisted ships face potential fines, detention, seizure or inclusion on a non-compliant vessels blacklist.

Tehran is simultaneously promoting a regional security bloc and alternative trade arrangements designed to reduce the bite of financial and shipping restrictions. Inside Iran, however, the economic strain is generating its own operational crisis. Senior Iranian energy management official Esmail Saqab Esfahani disclosed that politically connected members across major political factions are actively involved in fuel-smuggling networks draining 20 to 30 million litres of subsidised fuel daily. Leaked reports from an IRGC-Basij meeting and public warnings from former Economy Minister Ehsan Khandoozi indicate the regime is bracing for internal unrest during Shahrivar and Mehr, the period spanning late August to late October, driven by hyperinflation and rising prices.

The conflict is also accelerating procurement decisions in the defence sector. Interest in low-cost counter-drone systems, including so-called $5,000 “drone killers,” is growing as militaries seek cheaper ways to intercept inexpensive one-way attack drones. US forces have actively redirected dozens of vessels while deploying these new defence measures against asymmetric threats.

As of Monday, there were no confirmed new exchanges of fire. Whether the southern shipping corridor can absorb continued pressure, and whether the aviation network stabilises or contracts further, will depend on how quickly the diplomatic and sanctions picture shifts in the days ahead.
