Blanked sailings have stopped being an emergency measure. New analysis from Sea-Intelligence covering the first half of 2026 shows carriers routinely withdrawing between 10% and 14% of scheduled capacity on the four main east-west trades, month after month, in ordinary market conditions. If you book ocean freight out of Asia, that is roughly one in eight slots you thought existed and never got. The pandemic-era chaos has faded. The capacity discipline it taught the carriers has not.
What Happened
Sea-Intelligence reviewed blanked sailing activity across Asia-North Europe, Asia-Mediterranean, Asia-US east coast and Asia-US west coast for January through June 2026. Across all four trades, the consultancy found a persistent withdrawal band of 10% to 14% of advertised capacity. That is not a spike tied to Chinese New Year or a single Red Sea event. It is the baseline.
Compare that with the pre-2020 pattern, when blanking outside the Lunar New Year lull was unusual enough to make headlines. Carriers have kept the tool and normalised it. Alliance reshuffles, slower steaming and longer Cape of Good Hope rotations all absorb ships, and what is left gets managed week by week against demand. The result is a schedule that reads as a plan rather than a promise.
Impact on Freight Rates and Operations
Structurally tight supply puts a floor under spot rates. When 12% of a trade lane disappears at short notice, carriers do not need a demand surge to hold pricing. They only need to withhold enough boxes. For you that means fewer sharp rate troughs to buy into, and a narrower gap between contract and spot than the nominal overcapacity in the global fleet would suggest.
The operational hit is bigger than the rate hit. A blanked sailing pushes your container to the next vessel, which is usually seven days later and often already full, so rolled cargo compounds. Transit reliability degrades even when the ship that finally carries your box arrives on time. Warehouse labour booked for a Tuesday discharge, a retail promotion date, a production line waiting on components: all of it moves. Buffer stock that used to cover a three-day slip now needs to cover two weeks.
There is a documentation cost too. Rolled cargo means amended bills of lading, revised customs filings and renegotiated demurrage clocks at destination. Each of those is small on its own. Across a few hundred containers a quarter, they add up to real headcount.
What Shippers Should Do
- Plan to a 12% capacity haircut, not the published schedule. Take the carrier proforma, cut 10-14% from the sailings you actually count on, and see whether your inventory cover still holds.
- Split volume across two carriers in different alliances. Blanking decisions are made at alliance level, so a single-carrier programme concentrates your exposure into one set of choices you do not control.
- Push for written rolling protection in tenders. Ask for a named maximum roll period and a fallback commitment, then track performance against it monthly. Carriers concede this more readily on committed annual volume than on spot.
- Consolidate earlier and load denser. If you are getting fewer slots, each slot has to carry more. Cartonisation and pallet pattern work that saves half a container per booking is worth more now than it was two years ago.
Key Takeaway
Treat 10-14% blanked capacity as a permanent feature of east-west ocean freight and build your booking lead times, safety stock and carrier mix around it.
