Hormuz Traffic Collapses to 17% of Normal as ADNOC Vessels Hit and Iran Route Becomes the Only Visible Path

Estimated reading time: 4 minutes

Two vessels owned by Abu Dhabi National Oil Company (ADNOC) were attacked on 14 August while transiting the Strait of Hormuz, the latest in a string of kinetic strikes that has driven commercial traffic through the chokepoint to roughly 17% of pre-conflict levels and forced remaining operators to choose between an Iran-controlled northern corridor and a southern route where attacks have concentrated.

The UAE attributed the 14 August incidents to Iran. No injuries were reported on the ADNOC vessels, and the company said the situation was brought under control. A day later, the United Kingdom Maritime Trade Operations (UKMTO) reported that an unknown projectile struck the hull of a bulk carrier in the strait; the crew was safe, and a damage assessment was pending. The UAE’s Ministry of Foreign Affairs described the attacks as a flagrant violation of UN Security Council resolution 2817 and called on Tehran to halt the strikes and reopen the waterway unconditionally.

The collapse in Hormuz traffic is quantifiable and stark. UKMTO data for the seven days to 14 August recorded only 151 full transits, split into 75 outbound and 76 inbound movements. That is roughly 17% of the pre-conflict benchmark, when more than 130 vessels a day typically used the strait. The Joint Maritime Information Center (JMIC) maintains a SEVERE threat assessment for the area, citing persistent IRGC hailing, UAV overflights, surveillance, and kinetic activity, especially along the southern Omani approaches. Mine-related hazards also remain relevant near the traditional IMO Traffic Separation Scheme (TSS), which has seen negligible use in recent data.

The routing picture has bifurcated. Of the 151 weekly transits recorded by UKMTO, 45 used the northern, Iran-directed corridor (19 outbound, 26 inbound), while only 13 used the southern, Omani-side passage (8 outbound, 5 inbound). Just two vessels transited the traditional TSS outbound, and none inbound. Earlier reporting from 12 August found that all seven inbound vessels observed on that day used the Iranian route. The pattern is clear: operators willing to transit are gravitating toward the northern corridor, even though that means accepting Iranian direction, potential compliance requirements, and associated flag, ownership, and charter-party exposure.

The southern corridor, by contrast, has become the focal point of Iranian kinetic activity. Maritime intelligence sources indicate that projectile and drone incidents have concentrated along the Omani coast, where vessels avoiding Iran’s traffic system have been passing. The result is a constrained risk-management decision for charterers, forwarders, and project-cargo operators: the northern route may offer a higher probability of completing a transit, but it is not a “safe route” in any absolute sense, and overall traffic remains deeply depressed.

Kpler-based tracking showed only five commodity vessels moving through the strait on Saturday, 16 August, and none on Sunday. The firm recorded 31 commodity-vessel movements for the preceding week. These figures are not directly comparable to UKMTO’s weekly AIS and dark-derived totals, but they reinforce the same conclusion: for bulk, tanker, and energy-cargo operators, Hormuz passage is now exceptional rather than routine.

The operational implications extend well beyond the strait itself. Before the conflict, roughly a fifth of globally traded crude oil and natural gas passed through Hormuz. The current bottleneck is forcing exporters to draw down stockpiles, reroute via longer alternatives, or delay shipments. For project-cargo and heavy-lift operators, the strait’s closure or near-closure disrupts supply chains for energy infrastructure, industrial components, and construction materials moving between the Gulf, South Asia, and East Asia.

Iran and Oman are reportedly discussing potential shipping arrangements, but no confirmed operational agreement has restored normal commercial passage. The U.S. has warned Iran it will step up economic pressure following the latest attacks, and President Donald Trump has insisted the strait is “open” and under American control. Tehran, for its part, has not publicly accepted responsibility for the ADNOC incidents, though Iranian state media has previously framed attacks on vessels as responses to warnings ignored by ships using non-Iranian routes.

For the maritime industry, the immediate planning assumption is that Hormuz passage requires voyage-specific war-risk and P&I confirmation, pre-transit screening of vessels and beneficial cargo interests, updated AIS and security communications protocols, and built-in contractual provisions for delay, deviation, and cargo substitution. The strait is not closed in a legal sense, but in practical terms it is operating as a high-risk, low-volume corridor where the only visible path runs through Iranian-controlled waters.
