Ocean Freight Trends 2026: Blank Sailings Hide a Capacity Crunch

Ocean carriers are adding ships, but ecommerce importers should not assume that means more space—or cheaper freight. The latest data shows carriers are canceling sailings faster than scheduled vessel capacity is growing. In practical terms, the market can look oversupplied on paper while the space available on the sailing you need becomes tighter, less reliable, and more expensive.

That shift is already showing up in prices. On August 20, 2026, Drewry’s World Container Index rose 4% to $4,526 per 40-foot container, its third consecutive weekly increase. Shanghai-to-Los Angeles and Shanghai-to-New York spot rates both jumped 9% in one week. For brands planning holiday inventory, the lesson is clear: fleet growth does not protect you from a capacity crunch when carriers can selectively remove sailings.

More Ships Do Not Automatically Mean More Bookable Capacity

A blank sailing occurs when an ocean carrier cancels a scheduled voyage or withdraws that voyage’s capacity from the market. The ship may still exist, and the carrier’s global fleet may still be growing, but importers cannot book space on a sailing that does not operate.

A new Supply Chain Dive report, based on Sea-Intelligence research, shows how sharply the two measures diverged when comparing the first half of 2026 with the first half of 2019:

• On the Asia–North America East Coast trade lane, scheduled capacity grew 46%, while blanked capacity surged 215%.
• On the Asia–North America West Coast trade lane, scheduled capacity grew 16%, while blanked capacity increased 62%.

This does not mean every trade lane has less total capacity than it did in 2019. It means the headline growth in fleet and scheduled capacity overstates the capacity importers can actually use. Carriers can add vessels while still controlling the supply offered on specific routes through cancellations, vessel redeployment, slower sailing speeds, and service changes.

The Freight Rate Story Has Reversed

In 2025, importers could point to a steep drop in transpacific spot rates and treat cheaper ocean freight as a margin opportunity. That is no longer a safe description of the current market.

According to Drewry’s August 20, 2026 assessment:

• The composite World Container Index rose 4% to $4,526 per 40-foot container.
• Shanghai-to-Los Angeles spot rates rose 9% to $6,802.
• Shanghai-to-New York spot rates rose 9% to $9,507.
• August capacity fell 9% month over month from Asia to the U.S. East Coast and 0.4% to the U.S. West Coast.

Drewry also reported seven blank sailings for the following week and expected transpacific rates to remain stable because of tightened capacity. The key point is not that rates will rise every week. It is that carriers have shown they can withdraw enough supply to interrupt the normal assumption that a larger fleet must push prices down.

The cancellations are concentrated, too. Drewry counted 49 blank sailings across major East–West routes between August 17 and September 20, equal to 7% of scheduled sailings. Nearly 60% of those cancellations were on the eastbound transpacific trade. A global cancellation rate can therefore look manageable while a specific Asia-to-U.S. service experiences much tighter conditions.

Demand Is Not Collapsing—The Peak Moved Earlier

The capacity cuts are not occurring in a simple demand collapse. The National Retail Federation’s August Global Port Tracker said U.S. ports handled 12.7 million TEU in the first half of 2026, up 1.1% from the same period in 2025. It expects full-year volume of 25.5 million TEU, essentially flat at 0.1% growth.

What changed is the timing. Importers pulled inventory forward to reduce exposure to tariffs and other disruptions, producing an earlier and smoother peak season. NRF projected July imports at 2.21 million TEU, down 7.6% year over year, and August at 2.22 million TEU, down 4.2%.

That combination—roughly flat annual demand, a peak that arrived early, and a softer late-summer booking curve—gives carriers room to cancel sailings without abandoning pricing discipline. Sellers should not interpret lower monthly import forecasts as proof that space will be readily available when they need it.

Why Ecommerce Sellers Should Care

A freight quote is only one component of the true inventory cost. A lower rate does not create savings if a cancelled sailing causes the shipment to roll, inventory arrives after a promotion begins, or the brand has to replenish by air.

Blank sailings can create four downstream costs that never appear in the initial ocean quote:

• Rolled cargo: Containers are pushed to a later sailing, extending the replenishment cycle.
• Longer and less predictable lead times: A missed weekly sailing can add days before the vessel even departs.
• Stockouts or emergency freight: Brands may lose sales or replace delayed ocean inventory with expensive air shipments.
• Receiving disruption: Delayed containers can arrive in bunches, creating drayage, appointment, labor, and storage pressure at the destination warehouse.

The right question is no longer simply, “What is the cheapest rate?” It is, “What is the lowest landed cost after accounting for the probability and consequence of delay?”

Tariffs Still Matter, but This Is Not a Tariff-Free Window

The United States has suspended the heightened reciprocal tariff rate on Chinese imports until November 10, 2026. But the current 10% reciprocal tariff remains in effect, and other applicable U.S. tariff measures remain separate. Importers should therefore avoid describing the suspension as a tariff holiday.

The timing still matters. Inventory arriving before or after a tariff change can carry a different landed cost, but rushing cargo onto a fragile sailing schedule creates its own risk. The better approach is to model tariff exposure and transportation reliability together rather than treating the freight rate as an automatic offset to duties.

A Practical Playbook for the Next 60–90 Days

• Track offered capacity by service, not fleet growth.
  Monitor blank sailing announcements for the exact carrier, alliance, origin port, destination port, and service string you use. A global capacity number will not tell you whether your preferred departure will operate.
• Add at least one sailing cycle to critical-item planning.
  If a product cannot tolerate a one-week roll, move the booking cutoff earlier or hold more buffer inventory. Do not use the same safety stock for a stable service and a frequently blanked one.
• Diversify the route, not just the carrier name.
  Two carrier brands may share the same alliance service or vessel. Ask whether alternative bookings actually use a different service string, gateway, or sailing day.
• Prioritize margin and availability.
  Reserve the most reliable capacity for high-margin, fast-moving, and promotion-critical SKUs. Slow-moving products can tolerate a cheaper, less certain service more easily.
• Model the total landed-cost range.
  Compare base freight, tariffs, canal or fuel surcharges, demurrage risk, inventory carrying cost, and the cost of a one- or two-week delay. Use best-case, expected, and disruption scenarios.
• Keep receiving plans flexible.
  Share revised ETAs with drayage providers and fulfillment partners early. When blank sailings cause vessels to bunch, pre-arranged receiving capacity can prevent an ocean delay from becoming a warehouse delay.
• Avoid overcommitting at the top of the market.
  Rates have risen sharply, but carrier capacity management can change quickly. Balance committed volume with enough flexibility to benefit if additional sailings return or demand softens.

What to Look for in a Fulfillment Partner

Ocean schedule volatility does not stop when the container reaches port. The receiving network has to absorb inventory that may arrive late, early, or in a surge. When evaluating a 3PL or fulfillment network, ask:

• Can it adjust receiving appointments when vessel ETAs change?
• Can it rapidly make newly received inventory available for sale?
• Can it distribute inventory across multiple fulfillment nodes based on current demand?
• Can it handle short-term receiving and order-volume spikes without creating a second bottleneck?
• Does it provide visibility into inventory by location so merchandising and operations teams can make the same decisions?

A flexible, multi-node fulfillment strategy cannot prevent a blank sailing. It can reduce the damage once inventory arrives by helping brands position products closer to customers, restore availability faster, and avoid concentrating all inventory and receiving risk in one facility.

The Bottom Line

The ocean freight market is sending two signals at once: the global fleet is larger, but carriers are withdrawing more of the capacity that importers expected to use. That is why prices can rise and cargo can roll even when the industry appears oversupplied.

For ecommerce brands, the winning strategy is not to predict the lowest possible spot rate. It is to protect the availability and margin of the inventory that matters most while preserving flexibility for everything else.

Key takeaways:

• Measure bookable capacity, not just vessel capacity.
• Plan critical inventory around the risk of one missed sailing.
• Evaluate freight rates together with tariffs, delay risk, and inventory cost.
• Coordinate ocean ETAs with drayage, receiving, and multi-node inventory plans.

Frequently Asked Questions

What is a blank sailing?

A blank sailing is a scheduled ocean voyage that a carrier cancels or withdraws. Cargo booked on the service may be moved to a later vessel, creating longer lead times and possible receiving disruption at the destination.

Why can freight capacity feel tight when carriers are adding ships?

Fleet capacity measures the ships carriers own or deploy, while bookable capacity measures the space actually offered on a specific trade lane and sailing. Carriers can reduce bookable capacity through blank sailings, vessel redeployment, slower speeds, or service changes even while the global fleet grows.

Are transpacific ocean freight rates rising or falling?

They were rising as of August 20, 2026. Drewry reported 9% weekly increases on both Shanghai-to-Los Angeles and Shanghai-to-New York, with the composite World Container Index up 4%. Rates remain volatile, so importers should monitor the exact lane and service rather than rely on a global average.

How should importers prepare for blank sailings?

Monitor cancellations by service string, book critical inventory earlier, maintain genuinely independent route options, and add at least one missed-sailing scenario to inventory planning. Brands should also update drayage and warehouse receiving plans when vessel ETAs change.

Does the China tariff suspension mean Chinese imports are tariff-free?

No. The heightened reciprocal tariff rate is suspended until November 10, 2026, but the current 10% reciprocal tariff remains in effect, along with other applicable tariff measures. Importers should calculate duties at the product and country level.

How can a multi-node fulfillment network reduce ocean freight risk?

It cannot prevent an ocean carrier from cancelling a sailing, but it can help a brand recover faster after inventory arrives. Flexible receiving and distributed inventory can reduce replenishment time, shorten customer delivery distances, and prevent all inbound and fulfillment risk from accumulating at one warehouse.
