Hormuz Transits Resume Under US-Iran Ceasefire; IMO-Oman Coordination Manages Backlog

Vessel traffic through the Strait of Hormuz is increasing following the US-Iran memorandum of understanding signed June 22-23, with international coordination through the IMO and Oman managing the phased reopening of the waterway. Allied Shipbroking reports transits have 'begun to breathe again, but only just,' with completed passages rising as stranded ships move through the corridor.

The logistics reopening is the hard test of the ceasefire's durability. Diplomatic agreements can survive on ambiguity; shipping schedules cannot.

If vessel transits remain depressed through early July despite the agreement, it signals one of three things: (1) Iran is quietly maintaining chokepoint pressure to extract concessions in the 60-day negotiation window; (2) shipping insurers haven't actually repriced Hormuz risk downward and are routing around the strait anyway; or (3) the Suez/Port Said congestion is the binding constraint, not Hormuz.

Any of these would indicate the ceasefire is theater.

WHY IT MATTERS

The reopening signals that the 60-day ceasefire framework is operationalizing at the logistics level — not just diplomatically.

Shipping insurers, energy traders, and regional logistics operators (Maersk, MSC, major Middle East port operators) can now price Hormuz transit risk down from war-premium levels, which directly reduces the cost of moving 21% of global traded oil and LNG through the strait.

The constraint is not capacity but coordination: IMO and Oman are managing the backlog of stranded vessels, implying a bottleneck at Port Said (Suez) or regional hub congestion rather than Hormuz itself. Watch the weekly AIS transit counts through mid-July — if they stabilize above 2,000 transits/week (pre-June baseline was ~2,400), the ceasefire is holding at the operational level.

If they stall or spike downward again, either Iran or the US has signaled intent to resume pressure.

WHAT THIS DOESN’T TELL US

What is the actual current backlog of stranded vessels waiting for Hormuz passage, and what is the estimated time-to-clear? The article says transits are 'picking up' but provides no baseline count or timeline for full normalization.
