Hormuz Traffic Splits as Ceasefire Collapses — 11 July 2026

The collapse of the June US-Iran ceasefire, declared over by President Trump on 10 July, has re-ignited attacks on commercial traffic in the Strait of Hormuz and forced a rapid re-pricing of risk for every owner still carrying crude or products through the 21-mile-wide chokepoint.

Southern Route Tanker Counts Drop to Single Digits

INTERTANKO guidance issued after the latest exchanges shows south-bound VLCC and Suezmax transits via the deeper, less exposed lanes have fallen to single digits per day. Owners who can accept longer ballast legs are diverting around the southern tip of Oman rather than risk the narrow inbound lane where Iranian fast-attack craft have concentrated. The move adds roughly four days and $180,000 in fuel and time-charter costs on a typical Middle East Gulf-to-Asia voyage.

New Treasury Designations Hit Financiers and Exchange Houses

US sanctions announced the same day target a financier linked to senior Iranian leadership plus several exchange houses that have facilitated payments for fuel and spare parts. P&I clubs are already circulating updated war-risk questionnaires; any vessel that has called an Iranian port since 1 June or used a sanctioned entity for bunkers now faces potential cover withdrawal within 48 hours of notice.

UN Shipping Agency Rejects Iranian Traffic-Control Plan

The IMO governing council on 10 July formally rejected Tehran’s unilateral creation of a new Hormuz traffic authority and reaffirmed that coastal states may not impose sovereignty over the strait beyond the limits of the 1982 Law of the Sea. Flag states with tonnage in the Gulf are being urged to issue fresh navigation warnings citing the council’s statement as the legal baseline for any future insurance or charter-party disputes.

June Transit Data Shows Partial Resilience

Lloyd’s List Intelligence recorded 576 Hormuz transits in June, more than double May’s 233, yet still only 18 percent of the 3,131 movements logged in June 2025. Non-Iranian flagged vessels accounted for 70 percent of the total, indicating that many owners have already accepted higher war-risk premiums rather than exit the Gulf entirely. The data also shows a clear split: laden crude carriers have thinned fastest, while product and chemical tankers continue to move when charter rates justify the exposure.

Tanker Indices Firm as Risk Premia Return

The Baltic Dirty Tanker Index and TD3C Middle East Gulf-to-China route both reversed their post-ceasefire decline within 48 hours of the first new attack. Charterers seeking July liftings are now quoting 20–25 percent war-risk surcharges on top of the base rate, with most owners insisting on 50/50 sharing rather than the 100 percent owner-borne terms that prevailed in early June.

Container and Dry-Bulk Markets Largely Unaffected

Transpacific and Asia-Europe container spot rates posted modest single-digit gains driven by peak-season demand, not Hormuz risk. The Baltic Dry Index rose 1.2 percent to 2,944 points on capesize strength unrelated to the strait. These segments remain insulated because their principal routes avoid the Persian Gulf altogether.

The Questions Worth Asking Today

For an owner with a VLCC fixed to load at Ras Tanura on 15 July, what is the realistic war-risk premium today?

Most clubs are quoting an additional 0.35–0.45 percent of hull value for a single Hormuz transit; some London syndicates have already withdrawn quotes and are waiting for the next 72-hour assessment cycle.

For a charterer considering a spot clean-products fixture from Jubail to Singapore, will the southern route remain viable if attacks continue?

The southern diversion adds four days and roughly $180,000; at current freight levels the cargo can absorb the cost, but any further spike in bunker prices would tip the economics back toward the strait.

For a P&I club that has already issued a 48-hour notice on Iranian-linked calls, what triggers automatic cover suspension?

A single call at an Iranian port after 1 June or any payment routed through a newly sanctioned exchange house is enough to activate the suspension clause without further notice.

For a master whose vessel is currently anchored off Fujairah awaiting orders, what routing instruction should the owner expect within the next 24 hours?

Most managers are instructing masters to remain at anchor until a revised war-risk certificate and updated charter-party addendum are received; south-bound departures are being held pending daylight confirmation of clear lanes.

For a manning agency with Filipino ratings on a tanker due to transit Hormuz next week, what additional insurance or compensation clauses are now standard?

Owners are adding a one-off $5,000 high-risk bonus per seafarer plus double war-risk death-and-injury cover for the duration of the strait passage.

Triggers to Watch Before 14 July

Any fresh Iranian fast-attack craft movement reported inside the 12-mile territorial sea between 48 and 72 hours from now will trigger automatic 0.5 percent premium increases. A US Treasury designation naming additional exchange houses will force clubs to issue fresh questionnaires within 24 hours. The next scheduled INTERTANKO Hormuz advisory update, expected 13 July, will either confirm the single-digit southern-route figure or show a rebound that signals owners are testing the strait again.
