What was the global schedule reliability rate in Q2 2026 and how does it compare to pre-pandemic levels?

Global liner schedule reliability reached 63.1% in Q2 2026, representing a 2.2 percentage point improvement from Q1. However, this remains well below the 70-80% reliability band that was standard during pre-pandemic Q2 quarters from 2013 to 2020, indicating the industry has not yet recovered to historical norms.

Why are carriers prioritizing core trade lanes at the expense of regional services?

Geopolitical tensions are forcing carriers to concentrate their limited capacity and resources on the highest-volume, most profitable core trade lanes to maintain performance metrics and revenue. Regional services, which are typically lower-margin, are receiving less investment and operational focus, resulting in fragmented reliability across the global network.

What should supply chain teams do if they rely on regional or secondary shipping routes?

Companies dependent on regional trade lanes should implement more aggressive schedule buffers, increase inventory safety stock, diversify carrier relationships where possible, and adjust customer lead time commitments upward. Closer coordination with freight forwarders and real-time shipment tracking becomes critical to manage schedule variability.

How long is this fragmentation likely to persist?

The article does not specify a timeline, but the structural nature of geopolitical constraints suggests this two-tier reliability model could persist for months or longer. Recovery to pre-pandemic reliability levels across all trade lanes will likely require stabilization of underlying geopolitical tensions and normalization of carrier capacity constraints.

Which trade lanes and regions are most affected by declining reliability?

The article identifies this as a global fragmentation trend but does not specify which particular trade lanes or regions see the worst performance. The implication is that core intercontinental lanes (Asia-Europe, Asia-North America) are being prioritized, suggesting secondary routes including intra-regional services are experiencing the most degradation.

The signal

Global container shipping is experiencing a bifurcated operational landscape where schedule reliability improvements mask a troubling underlying trend: carriers are strategically abandoning regional service consistency to protect performance on high-volume core trade lanes. 2 percentage points from Q1—this headline figure obscures a fragmentation problem that threatens smaller shippers and regional economies. The fundamental issue stems from geopolitical pressures forcing carriers to concentrate resources on the most profitable, strategically important routes while allowing reliability to deteriorate on secondary and regional services.

This represents a structural departure from pre-pandemic norms, when the industry maintained 70-80% reliability across most services. Supply chain professionals now face a two-tier shipping environment where access to consistent, reliable service depends heavily on which trade lanes their business uses. For shippers and freight forwarders, this trend demands immediate strategy reassessment.

Companies relying on regional or secondary trade lanes should anticipate longer, more variable transit times and plan inventory and customer commitments accordingly. The gap between core-route and regional-route performance is likely to persist as long as geopolitical factors constrain carrier capacity and routing flexibility, making schedule cushioning and contingency planning essential components of regional supply chains.

Frequently Asked Questions

What This Means for Your Supply Chain

Simulation Suggestion

this month

What if regional shipping transit times increase by 20-30% due to continued carrier capacity prioritization?

Simulate the impact of reduced frequency and increased schedule variability on secondary and regional trade lanes over the next 6 months. Assume core routes maintain current reliability levels while regional services degrade further due to carriers reallocating capacity to high-volume corridors. Model effects on inventory buffers, lead times, and customer service levels for shippers dependent on these routes.

What if you shift sourcing from a regional supplier to a core-route supplier to gain schedule reliability?

Model the total cost of ownership impact if a company switches sourcing from a regionally-served supplier to one located on a major core trade lane. Compare landed costs, inventory carrying costs, lead time variability, working capital effects, and customer service improvements against supplier pricing differences and minimum order quantity changes.

Simulation Suggestion

What if you increase safety stock by 15% for regional shipments to absorb schedule variability?

Simulate the carrying cost and working capital impact of increasing safety stock levels by 15% across all products sourced via regional and secondary trade lanes. Calculate the tradeoff between improved service level consistency and increased inventory holding costs, obsolescence risk, and warehouse space requirements over a 12-month horizon.
