If your supply chain depends on ocean freight, you already know things have been rough. But here's a number that puts it in stark perspective: 49.9%.
That's the global container shipping schedule reliability reading for August 2026, according to Sea-Intelligence. In plain terms, it means more than half of all container ships worldwide arrived late last month. This is the second consecutive monthly decline-and the lowest reading since September 2022. Late-arriving ships averaged 6.81 days behind schedule, the highest since March 2022 and nearly two full days worse than the same time last year.
For shippers, this isn't a statistic. It's a delayed production line. A missed delivery window. A warehouse running on empty.
This Is What "Operational Reality" Looks Like
The deterioration is not evenly spread. Asia–North America west coast reliability fell 8.8 percentage points to 60.6%. Asia–North America east coast dropped 9.6 points to 61.7%. Asia–North Europe slipped 2.4 points to 62.3%, while Asia–Mediterranean fell 3.7 points to 61.8%.
Across the 34 tradelanes tracked, only three recorded any month-on-month improvement. And among the 13 largest carriers, not a single one improved its reliability over the month. Year on year, all 13 recorded worse performance. Maersk managed the smallest year-on-year decline at 8.9 percentage points; PIL suffered the largest at 31.1 points, one of 12 carriers to post a double-digit annual drop.
The Real Story: It's No Longer a Phase
Here's where DP World's perspective changes the conversation. The terminal operator's latest white paper, released to mark World Maritime Day 2026, makes a point that shippers need to hear clearly: disruption is no longer episodic. It has become a structural feature of global trade.
The white paper points to a convergence of forces reshaping how cargo moves: geopolitical tensions, evolving trade policies, climate-related disruption, and shifting manufacturing footprints. "These are not isolated challenges," DP World notes. "Together, they represent a structural shift in the way global trade is organised."
The Red Sea crisis is the clearest example. Suez Canal traffic fell to roughly half its 2024 level last year, while vessel capacity rerouted around the Cape of Good Hope increased 89%. Longer journeys meant longer transit times, higher costs, higher emissions-and yes, worse schedule reliability.
What This Means for Your Cargo
Shippers need to stop planning around "things getting back to normal." The data says otherwise. What's happening now is the environment you need to operate in-not wait out.
That reality puts a premium on the things that actually help when schedules slip: real carrier relationships, genuine routing flexibility, and visibility that tells you what's happening before you find out the hard way.
The Kind of Partner This Market Demands
This is precisely where Xiamen AE Global comes in.
We've been moving freight through exactly this kind of market since 2018. We are a government-licensed company with IATA, FIATA, FMC, and NVOCC approvals-credentials that mean we operate with direct carrier access, not through layers of middlemen who disappear when things get difficult.
We work with over 100 overseas agents worldwide. That's not a networking list. It's a live system of partners on the ground at ports across Asia, Europe, and beyond. When reliability drops on a major east-west lane, we are already talking to our partners about alternative routings, feeder connections, and contingency plans-before our clients' cargo becomes a statistic.
Our multimodal capability is another layer of protection. When ocean schedules are unreliable, we can pivot to air freight through our IATA-certified operations or shift to rail where the geography allows. For time-sensitive or high-value cargo, that flexibility is the difference between meeting a deadline and missing it.
We've invested heavily in real-time visibility tools that give our clients genuine transparency-actionable insight into where their containers are and what's happening next, not a tracking number that just sits there. And because we handle LCL consolidation ourselves rather than outsourcing it, we maintain tighter control over space allocation and container availability even when schedules are in disarray.
The Takeaway
Reliability below 50% is not a temporary glitch. It is the operational reality DP World is telling the industry to plan around. The shippers who navigate this successfully will be the ones who stop waiting for a return to "normal" and start building supply chains designed for volatility.
At Xiamen AE Global, we don't just move boxes. We help clients operate in the market as it actually is-with the relationships, technology, and multimodal reach to keep cargo moving even when the schedules don't.
If your supply chain needs a partner built for volatile markets, contact Xiamen AE Global. Let's talk about what reliable logistics looks like when reliability itself is in short supply.
