What does it mean that 4.3 million TEUs are 'out of circulation'?

TEUs out of circulation are containers trapped in port queues, warehouses, or intermediate storage, unable to be repositioned for the next shipment. Instead of cycling rapidly between origin and destination, they remain stalled, effectively shrinking the operational container pool and forcing shippers to use alternatives (air freight, smaller shipments, or other vessels). This reduces overall supply chain capacity.

How does port congestion drive shipping costs higher?

When ports are congested, vessels wait longer at berth (demurrage charges), containers incur storage fees, and truckers face detention costs. Shippers pay premium rates to prioritize their loads, and congestion allows carriers to maintain pricing power. With fewer containers available for circulation, competition for capacity intensifies, pushing rates upward across affected lanes.

Which industries are most vulnerable to this congestion?

High-volume, time-sensitive sectors are most exposed: retail (back-to-school and holiday seasons require predictable inbound flows), automotive (just-in-time parts), electronics (short product lifecycles), and perishables (cold chain dependent on rapid transit). Manufacturing sectors relying on imported raw materials or components also face extended lead times and inventory risk.

Is this congestion temporary or a structural problem?

The scale (4.3 million TEUs) and characterization as 'all-time highs' suggest structural challenges beyond seasonal fluctuations. Port capacity expansion is slow, vessel right-sizing is ongoing, and hinterland logistics infrastructure in many regions remains constrained. This points to multi-quarter or longer-term pressure, not a near-term resolution.

What actions should companies take to mitigate this impact?

Consider diversifying ports of entry, shifting to alternative trade lanes with less congestion, negotiating longer lead times with suppliers, building safety stock for critical materials, exploring nearshoring to reduce maritime dependency, and using predictive visibility tools to track container positions. Air freight premiums may be justified for high-value or time-critical SKUs.

The signal

Global container port congestion has reached unprecedented levels, with over 4.3 million twenty-foot equivalent units (TEUs) currently out of circulation. This represents a structural challenge to supply chain fluidity, as containers remain stuck in port bottlenecks rather than cycling back to origins for reload. The congestion is driving up transportation costs, extending transit times, and forcing companies across industries to reassess inventory strategies and supplier networks.

For supply chain professionals, this situation signals a fundamental shift in operational planning. When containers cannot cycle efficiently, the effective global container fleet shrinks, reducing capacity and pushing costs upward across all trade lanes. Companies relying on just-in-time inventory models face particular risk, as predictable transit windows narrow and variability increases.

The congestion is likely structural rather than temporary, pointing to systemic port infrastructure challenges that cannot be resolved quickly.

What This Means for Your Supply Chain

Simulation Suggestion

immediate

What if transit times increase by 3-4 weeks due to port delays?

Simulate a scenario where ocean transit times from Asia to Europe extend by 3-4 weeks beyond baseline due to port queue times and vessel congestion. Model impact on inventory levels, safety stock requirements, and demand forecast accuracy for time-sensitive products.

What if container availability forces a 15-20% freight cost increase?

Model the financial impact of elevated shipping rates across key inbound routes due to scarce container capacity. Assess cost absorption versus price-passing strategy, margin pressure, and competitiveness for different product categories.

What if we shift 30% of volume to alternative ports or modes?

Scenario: redirect a portion of container volume to less-congested ports (feeder ports, alternate gateways) or accelerate adoption of air freight for high-value items. Model cost trade-offs, service level improvements, and supply chain resilience gains.
