Hormuz Closure Keeps Ocean Freight Firm as Lumber Peaks

Do not read the late-July freight dip as relief. The Strait of Hormuz has been effectively closed to commercial shipping since US and Iranian forces resumed fighting in July, with traffic down roughly 90% year on year and almost no tanker transits in the final week of the month, per Lloyd's List Intelligence and UN News. Container spot rates eased slightly in the same stretch, but the bigger force sitting under Asia-to-Europe and Asia-to-US freight is a live geopolitical shock. For plywood buyers pricing fourth-quarter orders, the working assumption should be firm-to-higher landed costs, not a discount.

Why the freight dip won't hold

The Drewry World Container Index did slip, from a 22-month high of $4,639 per 40-foot container on 9 July to $4,374 by 23 July, on figures compiled by IndexBox. That is a small move in a stretched market. It still sits about 61% above the same week last year. Transpacific lanes stayed pricey, with Shanghai to New York near $7,904 and Shanghai to Los Angeles around $6,482, while Shanghai to Genoa held near $6,463. Carriers are not behaving like a market that is topping out. Peak-season surcharges are stacking through the third quarter, with CMA CGM adding $1,400 per TEU on Far East to Mediterranean cargo from 1 July, and blank sailings are being used to defend those levels. The Hormuz disruption reroutes and lengthens voyages that touch the Gulf and the Red Sea, and that keeps upward pressure on rates and bunker costs into August. From a Vietnamese mill's desk, we are not budgeting Q4 around a dip that one quiet week produced.

The cost line you won't see quoted

The freight rate is not the whole bill. War-risk insurance premiums for Strait of Hormuz transits have climbed from around 1% of hull value before the fighting to a range of 7.5% to 10% as of 22 July, according to figures reported by The National and IndexBox. On a large tanker that works out to several million dollars per voyage against roughly a quarter of a million before hostilities. Box carriers do not sail the same hulls, but the same risk repricing feeds war-risk and bunker adjustment surcharges on any service that touches the Gulf or the Red Sea. A buyer can see a flat container rate and still pay more at the door once those surcharges settle. It is worth asking a forwarder to break out the war-risk and bunker lines on Europe-bound and US-East-Coast quotes rather than reading the base rate alone.

Lumber's wildfire premium

The raw-material side is pushing the same way. Global Wood Markets Info reported on 22 July that lumber reached a one-year high as wildfires spread across Canada, tightening a supply base that was already thin. British Columbia has closed 21 mills since 2023, and North American sawmill capacity has fallen about 6% year on year after a run of shutdowns led by West Fraser. Trading Economics data put lumber near $640 per thousand board feet in mid-to-late July, the strongest since August 2025. Forecasts compiled by FastBull see prices staying volatile in a $580 to $650 band through year-end. Softwood does not set the price of plantation-grown hardwood plywood, but a wildfire premium on competing structural panels lifts the floor under the whole category.

Squeezed from both sides

Put the two together and the delivered-cost stack is firming from both directions at once. Shipping is elevated and exposed to a geopolitical shock, and raw wood is at a one-year high. That is a different picture from a normal peak season, where one leg usually offsets the other. Buyers who deferred through the summer expecting a Q4 pullback are now facing a market where waiting carries real cost. The practical read is to cover known fourth-quarter needs against current prices rather than bet on a correction that the freight and lumber data do not support.

Beating the freight bill: load smarter

When freight is the volatile line, the lever buyers control is how much product rides in each box. Panel weight drives it. Lighter plantation-grown cores such as Acacia load more sheets into a 40-foot container than denser eucalyptus-core panels of the same specification, which trims the freight cost carried by every cubic metre delivered. In a market where a single lane can move double digits in a week, that packing efficiency is a durable saving rather than a one-off. It is worth running the numbers on core species and pallet configuration before booking, especially for Europe-bound and US-East-Coast orders exposed to the Hormuz and Red Sea routings. Our film-faced plywood range spans several core options for exactly this reason.

Demand and policy backdrop

Western demand still splits by building type. US single-family starts slipped to 895,000 in June, a third straight monthly decline and 3.2% below a year earlier, as mortgage rates kept buyers cautious, per the Census Bureau. Europe reads warmer, with ING and Euroconstruct expecting EU construction output to rise about 1.5% in 2026 after a flat 2025, led by civil engineering. On policy, the US Department of Commerce published its final antidumping and countervailing determinations on hardwood and decorative plywood from China, Indonesia and Vietnam in late July, cutting Vietnam's dumping margin sharply. Scope is the detail worth reading twice. The case targets hardwood and decorative plywood, and formwork, film-faced and structural panels are classified differently and sit outside it. A separate new US tariff on Brazilian wood products took effect on 22 July.

Outlook

Into August, the cost side has the upper hand. Freight will take its cue from the Gulf rather than from a single week of softer spot prints, and carriers are defending peak-season levels with capacity discipline. Lumber's wildfire premium will not clear quickly. Demand offers only a partial offset, with Europe's slow recovery and Asian restocking leaning against soft US single-family building. For buyers, the sensible move is to lock fourth-quarter volume now and treat any freight softness as a chance to book, not a trend to wait on.
