Supply Chain Action Points
Read this first — the conclusion, and the moves to make:
- By Monday 28 September, rebuild the lane sheet with only the four lanes in this release, printing this week's rate, the week-on-week change, the leading indicator and the trigger level for each; no plan is built off the composite.
- Freeze the European booking calendar at seven days for flexible cargo: hold Genoa and Rotterdam shipments that can wait one weekly cycle while weekly Suez transits stay at 48 or above, and release them the week the count stalls.
- Move every transpacific booking to confirmed space rather than confirmed rate: with announced blanks at 15 and up 67% week on week, require a slot confirmation before any supplier handoff or warehouse slot is committed.
- Write European contracts as index-linked with a plus or minus 5% collar reset monthly, and transpacific contracts as space-first with the rate secondary; both signed before the Q1 bid window closes.
- Set an automatic reversal rule: if weekly Suez transits fall back below 41, lock European capacity within 48 hours, cancel the deferral instruction, and accept the rate you get rather than the rate you wanted.
The Drewry World Container Index slipped 1% in the final week of September to $4,468 per 40ft box, dragged down by Asia-Europe where Shanghai-Genoa fell 5% to $3,835 and Shanghai-Rotterdam dropped 4% to $3,485. Vessels transiting the Suez Canal rose from 41 in week 37 to 48 in week 38, restoring effective capacity on the corridor. Transpacific held firmer: Shanghai-Los Angeles rose 2% to $7,838 while Shanghai-New York held at $10,373, with blank sailings announced for the coming week rising from 9 to 15.
The Analysis
Four thousand four hundred and sixty-eight dollars per forty-foot box, down one per cent. That is the number most of the coverage led with this week, and on its own it is the least useful number in the release. One per cent is forty-five dollars a box. Nobody runs a procurement calendar on forty-five dollars.
The parts moved much further than the average. Shanghai-Genoa fell 5% to $3,835. Shanghai-Rotterdam fell 4% to $3,485. Shanghai-Los Angeles rose 2% to $7,838. Shanghai-New York held at $10,373. Suez transits went from 41 in week 37 to 48 in week 38. Blank sailings announced for the coming week went from 9 to 15. Two corridors, two directions, one index.
A composite that prints minus one while its components print minus five and plus two is not describing a market. It is averaging two markets that happen to share a publication date. If you book both coasts, this is the week the average starts costing you money, because the average is the only number in the file that tells you to do the same thing on both.
Let us do the arithmetic the headline skipped. One per cent of $4,468 is $44.68 a box. A forty-five dollar move is inside the normal dispersion of FAK quotes on a single lane in a single week, and it is smaller than the gap between two forwarders quoting the same sailing. Meanwhile the spread inside the index is $4,353, the distance between Rotterdam at $3,485 and Los Angeles at $7,838, which is 125% of the Rotterdam number. You are being asked to react to 1% of the index. The thing that should change your behaviour is 125% of it.
Back out last week's levels and every move becomes a cheque. Genoa at $3,835 after a 5% fall implies $4,037 the week before, so $202 a box left that lane in seven days. Rotterdam at $3,485 after 4% implies $3,630, so $145 left. Los Angeles at $7,838 after 2% implies $7,684, so $154 arrived. New York did not move at all, and a flat print on the most expensive lane in the index is itself information: the top of the transpacific has stopped rising, but it has not started falling. On the composite the week was worth $45. On a Genoa booking it was worth $202. Same seven days.
Now the capacity number, because it explains the rest. Forty-one to forty-eight transits is seven vessels, a 17% increase week on week. Seven ships is not a fleet; it is one string and a partial. But rate sensitivity on a corridor is not linear in vessel count, because this corridor had been running below its effective capacity and the first vessels back do more damage to price than the tenth. That is the mechanism behind a 4% to 5% fall on two European legs in the same week the transit count rose 17%.
The chain runs in one direction and it is not demand. Security conditions improve enough for a handful of operators to accept the routing. Each returning string adds capacity on Asia-Europe without adding a single container of demand. The marginal box on that corridor clears lower. The index prints minus four and minus five on the European legs. European demand did not fall this week. What fell was the freight rate, because supply on the corridor rose. That distinction decides how you treat the discount. A demand-led fall is a warning about your order book. A supply-led fall is a gift with an expiry date, and the expiry date is set by whoever is shooting at ships, not by you.
The transpacific ran the opposite mechanism, and the tell is in the blank count. Nine to fifteen is six sailings, a 67% increase, announced on a lane where the spot rate still rose 2%. Carriers do not withdraw capacity from a lane they expect to defend on price alone. Blanks are what defending looks like: you remove the sailing rather than discount the box. That is how Los Angeles adds $154 while the composite loses $45. The same carriers are managing two corridors in opposite directions in the same week, and on the US side the tool is withdrawal, not price.
Here is where I stop agreeing with the standard read. The comfortable story is that Suez is reopening, Europe is softening, and the US is holding. The correct story is that those are two ends of one capacity decision. A carrier has a fixed fleet and two contested corridors. The marginal vessel goes where the rate is defending. This week the Pacific defended and Europe did not, and the European legs were allowed to clear 4% to 5% lower precisely because the capacity arriving through Suez had to be employed somewhere. Tonnage returning to the Red Sea corridor is tonnage that does not have to be pushed into the Pacific at full strength. The two prints are not independent observations. They are one allocation, reported twice.
A number that needs a warning label is the fifteen. Fifteen is announced blank sailings, not cancelled ones. Announcement is a price signal before it is an operational fact. Carriers publish blanks to test whether the market will absorb the withdrawal, and a portion get reinstated when the bookings arrive. So the 9 to 15 move is strong evidence of intent and weak evidence of capacity. That cuts both ways operationally. Buy space against the announcement and the sailing returns, and you have paid a premium for capacity that was never scarce. Ignore the announcement and it holds, and your cargo waits for the next available vessel, which in a fifteen-blank week is not next week.
One more thing about the forty-eight, because it is the number most likely to be misused. Forty-eight is a level, not a trend. One week of transit data is a point, and a point cannot tell you whether the corridor is normalising or whether seven operators made one cautious bet together. Drewry's own language is that the European slide will continue, which is directional and says nothing about the rate of change. Build a plan on the assumption that 41 to 48 is the start of a curve and you are forecasting from a sample of one. Treat 48 as a threshold to be re-read next Monday, not as a trajectory.
Transmission comes in three waves and they arrive on different clocks. The first wave is spot, and it is already here. Book FAK on the Mediterranean this week and the $202 is on the table today. Nothing to negotiate, nothing to model. The only question is whether the cargo can wait seven days, and for most industrial, furniture and packaging volumes the answer is yes.
Contracts are the second wave, and they land over the next four to eight weeks as Q4 top-ups and Q1 bids get priced. This is where the asymmetry bites. A carrier bidding the Pacific will quote you the composite, down 1%, as evidence of a calm market, and then price the Pacific at plus 2% with fifteen blanks behind it. Both statements are true, and that is the problem. Your counter is not an opinion, it is the component table: the lane you are buying printed plus 2% and the capacity behind it is being withdrawn at 67% week on week. Ask for the space commitment in the same document as the rate, and ask for it in writing.
Structure is the third wave, one to two quarters out. If Suez transits keep climbing, the European legs have room to keep falling and the next service rotation will reflect it. If the Pacific blanks persist, the alliance redeploys at the next change and the capacity you cannot get this month becomes the capacity that does not exist next quarter. Neither is visible in this week's print, and both are decided by the same allocation logic that produced this week's divergence.
Scale changes what the divergence is worth, and it changes it in an uncomfortable way. Assume a book of 200 FEU a month, split 120 to Europe and 80 to the US, which is a mid-size importer with two sourcing regions. On the European leg the week is worth $24,240 if the gateway is Genoa and $17,400 if it is Rotterdam. On the US leg it costs $12,320. Net, the month moves $5,080 to $11,920 in your favour. Direction right, magnitude is not a budget event. Note also the $57 a box gap between the two European moves, which is the number that decides whether your gateway choice was worth making.
Halve the book and the arithmetic halves with it. Assume 40 FEU a month, 24 Europe and 16 US. Europe is worth $4,848 on Genoa or $3,480 on Rotterdam. The US leg costs $2,464. Net saving: $1,016 to $2,384 a month. Under $2,400. At this size the value of reading the components is not the money, it is the mistake you avoid: deferring US cargo because the composite fell, then buying air freight in October to save a launch date. The avoided air bill is bigger than the captured rate saving, and it does not appear in any index.
Quarter the book again. Assume 8 FEU a month, 5 Europe and 3 US. Europe is worth $1,010 on Genoa or $725 on Rotterdam, the US leg costs $462, so the net is $263 to $548. You cannot trade an index at this size. What you can do is stop being wrong about which lane you are on, and the only lever worth management time is the booking date on those three US boxes. Move them earlier, not cheaper.
Direction changes the sign. An importer into Europe is on the right side of this: the ocean leg of the next container is 4% to 5% cheaper, and if the slide continues it will be cheaper again next month. An exporter selling into Europe is on the wrong side of the same number, because the customer can see it too and will ask for the difference inside one contract cycle. My advice to exporters is to get ahead of it and offer a rate-review clause tied to the index instead of a flat price, so the conversation happens on your schedule in a review rather than on theirs at renewal. On the US leg the sign flips: the importer's ocean cost rose 2% and the space behind it is being withdrawn, which is a worse combination than either number alone.
Category decides whether the window is usable at all. Fast fashion, seasonal launches, new product introductions and anything with a dated shelf life cannot use a two-week deferral; the markdown from a late landing is a multiple of $202 a box, and the freight difference is rounding error against it. Furniture, DIY, industrial components, packaging and replenishment stock can use it, because their demand does not expire on a date. The error I see most often is a category manager applying a lane-level rate conclusion to a SKU-level calendar. The rate is lane-level. The permission to wait is SKU-level. Those are not the same decision and they should not be taken in the same meeting.
The gateway question contains a piece of arithmetic most people skip. Genoa at $3,835 is $350 above Rotterdam at $3,485, which is 10% more on the ocean leg. But Genoa fell 5% and Rotterdam fell 4%, so the Med is closing the gap. If both speeds persisted for two weeks, which is an assumption and not a forecast, Genoa would print around $3,461 and Rotterdam around $3,212, and the gap would narrow from $350 to roughly $249. Fifty dollars a week of convergence, at those speeds. That does not justify switching a gateway, because the inland leg and the transit difference are not in the number. It does justify checking whether your Med routing is still priced off a stale Rotterdam benchmark.
The discount is a rental, not a purchase. Three things can end it inside a month. A security incident on the corridor reverses the transit count in days, and the seven vessels that came back go back out. A disruption at a North European gateway, the kind of industrial action that removes berth capacity overnight, spikes the North European rate while the ships are already at sea and makes the $350 Med premium look cheap. A carrier decision to stop defending the Pacific moves the blanks onto the Atlantic instead. None of that is in the index this week. All of it is one news cycle away.
Run the counterfactual the other way. If transits go 48 to 55 to 60 over the next month, the European legs keep falling and the correct move flips: stop committing forward, buy spot week to week, and do not sign a fixed Q1 at today's number. At the current weekly pace, and this is an assumption about persistence rather than a forecast, Rotterdam would print near $2,960 in four weeks, 15% below today. A fixed contract signed this week at $3,485 is then 15% above the market it was priced against. That is the cost of reading one print as a floor.
If blanks go from 15 to 20 and stay there, space becomes the binding constraint before price does, and the order of operations inverts. Book capacity first and negotiate price second, because a good rate on a sailing you cannot get onto is a number with no cargo attached. In that world the KPI is not dollars per FEU, it is confirmed slots per week against plan, and the person who owns it is whoever owns the booking desk, not whoever owns the budget.
A demand shock breaks the whole read. If a tariff deadline or a retail destock pulls volume out, blanks rise for a different reason, both corridors fall, and the divergence collapses into one direction. The discipline there is simpler and harsher: buy spot everywhere, shorten commitments, sign nothing longer than a quarter. The signal that you are in that world rather than this one is a pair: blanks rising on the Pacific while the Pacific spot rate stops rising.
The instrument that makes all of this delegable is a one-page lane sheet, reviewed every Monday after the index prints. Five columns per lane: this week's number, week-on-week change, the leading indicator, the trigger level, the action if the trigger fires. For Asia-Europe the indicator is weekly Suez transits and the level is 48. For the transpacific the indicator is announced blanks and the level is 15. A coordinator can run that sheet. It requires nobody to interpret an index, and it removes the most expensive habit in freight procurement, which is reacting to the composite.
On European contracts, the structure I would write this week is an index-linked rate with a collar, reset monthly. Assume a band of plus or minus 5% around the print. You give up the last 5% of a continued fall in exchange for not being exposed if the corridor reverses mid-quarter. On a lane falling 4% to 5% a week, that collar is not free, and I would still take it, because the reversal risk on this corridor is priced nowhere and a collar is the cheapest way to buy it.
On US contracts, do the opposite. Do not index-link into a firm market. Lock the rate and the space in one agreement and make the space commitment the primary term with the rate secondary. In a week with fifteen announced blanks, a rate-only agreement is a promise to be rolled, and a roll in the transpacific is a two-week delay plus an air freight decision, not a service hiccup.
The downstream trap is where the money actually goes. Warehouse slots, launch dates, supplier handoffs and retail booking windows all get committed against a sailing that may be on the announced blank list. Internal rule: no downstream commitment against a sailing on that list until the reinstatement deadline has passed. Two days of waiting costs nothing. A committed launch date behind a rolled sailing costs the air freight you buy to save it, and that bill is priced by somebody else.
One more use for the component table, and this one is for the negotiating room. The composite at minus 1% will be quoted at you as evidence of a stable market, usually in the same conversation as a Q1 increase on the Pacific. The reply is not an opinion. The Pacific printed plus 2%, the capacity behind it was withdrawn 67% week on week, and New York went flat at the top of the range. A market managed through withdrawal is not a stable market. It is a market where space is the scarce good, and you should be buying the scarce good.
Things I would not do this week. I would not switch a gateway to chase 4% to 5%, because the inland leg is not in that number and the re-qualification cost is real. I would not read one print as a trend; three consecutive prints in the same direction is a trend, one is a print. And I would not let a European conclusion leak into a Pacific booking, which is the specific error this week's composite invites.
One line for the file: the index fell 1%, the Mediterranean fell 5%, the Pacific rose 2%, and the only people who had a calm week were the ones who do not ship anything. If your book is 80% transpacific, this week's headline was a rumour about somebody else's cargo.
