Supply Chain Action Points
Read this first — the conclusion, and the moves to make:
- By 31 July, convert every July and August shipment into a confirmed booking with a named vessel and a container pickup date; nothing inside a 21-day sailing window should still be waiting for a quote.
- Measure days-to-full on your two main lanes every Monday; below 14 days is the signal to buy allocation for the next four weeks, not to renegotiate price.
- Do not sign a fourth-quarter contract benchmarked to the July 9 print as an all-in: use index-linked pricing with a collar of roughly plus or minus 15 percent around it, my suggested band, plus a routing clause that resets the rate at the first monthly print after any return to Suez.
- Stress the committed book at a 25 percent decline in the print, my assumption rather than a forecast; if losing competitiveness against spot buyers costs more than the gross margin on those SKUs, move that volume to floating price now and keep only the allocation fixed.
- Audit door cost against the print once a quarter; if your all-in door rate runs more than 20 percent above the port-to-port print on a comparable lane, the gap is charges and positioning rather than carrier pricing, and you are negotiating the wrong line.
Global container demand rose about 4% year-to-date through early July 2026, with year-on-year growth back near 3%, according to the latest ocean freight market update. Persistent Red Sea diversions around the Cape of Good Hope, longer voyage cycles and selective carrier capacity management kept the Drewry World Container Index near $4,639 per 40ft in the July 9 reading, well above historical averages. Space remains tight on Asia–Europe and transpacific lanes, with advance bookings recommended for July–August shipments.
The Analysis
Drewry's July 9 reading puts the World Container Index near 4,639 dollars per 40ft. Behind that print: global container demand up about 4 percent year to date through early July, year-on-year growth back near 3 percent, Red Sea diversions around the Cape of Good Hope still in place, voyage cycles longer, and carriers managing capacity selectively. Space is tight on Asia-Europe and the transpacific. Book early for July and August.
4,639 is a useful number and a dangerous one. Useful, because it is one of the few figures in this market you can independently check. Dangerous, because it is an average across a basket of lanes, quoted port-to-port, before the charges that make up your actual door cost, and because the thing holding it up is not demand. It is distance.
Here is what that distinction is worth, in dollars you can count and in a timing risk that stays invisible until the routing changes.
Run the two numbers against each other first, because they do not fit. Demand is up about 4 percent year to date and about 3 percent year on year. That is ordinary growth, close to the long-run trend for container trade. Ordinary demand growth does not produce a rate level well above historical averages. Something on the supply side has to be carrying the rest of it, and the source names it without dwelling on it: diversions around the Cape of Good Hope, longer voyage cycles, selective capacity management. Two of those three are the same mechanism in different clothes.
The unit that clears cargo is not a slot, it is a slot-day. A ship diverted around the Cape spends more days at sea for the same round trip. Same fleet, same nominal capacity, fewer round trips per year. Effective capacity falls without a single vessel being idled and without a single sailing being cancelled. That is how a market adds nominal capacity and still prints a firm rate. Selective capacity management is the second layer: with the routing already absorbing vessel-days, a carrier does not need to blank many sailings to hold the balance. Discipline is cheaper when geography does half the work.
Here are the numbers that matter, and they all come from that one print. Take 10 percent of 4,639 and you get 464 dollars per box; that is your unit of account for every argument in this piece. Suppose an importer moves 100 forty-foot containers a month, which is my assumption and not a figure from the source. A 10 percent move is 46,400 dollars a month. If the routing normalises and the print gives back 25 percent, also my assumption rather than a forecast, that is 1,160 dollars per box and 116,000 dollars a month on those 100 containers. Whether that is fatal depends on what is inside the box. On consumer electronics it is noise. On furniture, on seasonal apparel at the end of a season, on anything carrying a 15 percent gross margin, it is the margin.
Watch the basis, too, because it is where most comparisons go wrong. 4,639 is port-to-port, before origin and destination charges. If those charges are 20 to 40 percent of your door cost, that range is my assumption and not a published figure, then benchmarking your door rate against the print produces a gap that is partly charges and positioning, not carrier pricing. You will argue about the wrong line and lose the argument you should have won.
Now the part the coverage leaves out, and it is the part that decides how you sign. The reported line is that diversions keep rates elevated. The unstated corollary is that the elevated part is a freight-days premium, and a freight-days premium is refundable in full, without notice, at a moment nobody schedules. When the routing changes, the same ships complete more round trips within one voyage cycle. Effective capacity does not drift back, it snaps back, and it snaps back into a market that has been adding nominal capacity the whole time. The downside, when it comes, will therefore be faster than the upside was. Companies plan against an average. There is no average here. There are two regimes and a switch, and the switch is a routing decision rather than a market decision.
Who feels it first is a question about contract structure, not about size. Spot importers on Asia-Europe and the transpacific pay the print plus whatever premium the booking desk adds that week. A shipper with an annual contract and a fixed allocation is insulated until renewal, and the renewal date is the transmission date, which is why the pain arrives in a wave of identical contract conversations rather than gradually. Small importers without an allocation feel it in space before they feel it in price, and a lost booking costs more than a rate increase because the cargo misses a season that does not wait. Exporters on the backhaul see far less of the number; their binding constraint is equipment at inland depots, not the headhaul print. An exporter selling FOB is insulated on price and still competes for the same peak-season slots as everyone else.
Timing is where the index misleads by design, because it is an average of the last week and an average is a lagging thing. The leading indicator on your own account is days-to-full: how many days before sailing your lane closes. When that falls under 14 days, a threshold I set rather than one the source gives, you are in a tight window whatever the print says. The source's advice to book early for July and August is the same signal written in prose.
Take the counterfactual seriously, because it is the only way to see what you are actually paying for. If the Red Sea routing had normalised in the second quarter, the same fleet would have produced more voyages straight into peak season and the print would have fallen hard; what reads as peak-season momentum would have been revealed as a supply-side artefact. If the diversion persists through the fourth quarter, peak becomes a longer, flatter plateau, which is worse for planning than a spike, because you can see neither the top nor the turn.
The trap is signing an annual all-in at the July print with no routing clause. That trade buys the freight-days premium and hands the carrier a free option on normalisation: you pay 4,639 for twelve months while the market reprices below you, and the diversion that justified the number ends on a date you do not control. The index is a good thermometer and a bad clock. So buy the thing that is actually scarce. If days-to-full is under 14 and your fourth-quarter margin cannot absorb a 25 percent decline in the print on the volume you have already committed, lock the allocation and leave the price floating. In a market where the premium is refundable, space is the scarce good and price is the thing that gets handed back.
