CAx displays container availability at major ports worldwide. It indicates whether more loaded containers are imported or exported, revealing container shortages or oversupplies.
Use the index to make informed trading and leasing decisions.
How to interpret the CAx
A CAx of 50 means that the same number of containers enter and exit a port in the same week. A CAx above 50 indicates more containers are entering, while a CAx below 50 indicates more containers are exiting.

Become a pro at analyzing the CAx
0 – 45
- More demand for loaded container exports than for imports
- Likely increase in container rental fees
- Possible delays in cargo acceptance
- Could indicate a rise in cargo production if CAx is significantly below the long-term average
Extended periods below 45 suggest
- Insufficient container imports to handle export demands
- Container shortage
- Possible importation of empty containers to ease the shortage
45 – 55
- Balanced demand for export containers and full imports
Extended periods between 45 and 55 suggest
- Decrease in empty container movements
- Stable cargo production output
55 – 100
- Less demand for container exports than imports
- Likely decrease in container rental fees
- Could indicate a decline in cargo production if CAx is significantly above the long-term average
Extended periods above 55 suggest
- If during a shortage, it may signal that the shortage is easing
- Without a shortage, it indicates:
- Insufficient export demand to reduce the surplus
- Surplus may result from previously exported empty containers now returning as full imports
Frequently asked questions

What is the CAx?
The CAx (Container Availability Index) is a tool that allows you to monitor the import and export movements of full containers at major ports. A CAx value of 50 means the same number of containers enter and leave a port in the same week. CAx values above 50 indicate more containers entering, while values below 50 indicate more containers leaving a specific port.

Which equipment types are included in the CAx?
The CAx index is based on a large sample of our tracking data. However, it should be considered a rough segmentation as the percentages might change slightly with each update.
- 20ft containers:
- 98% are 20DC (20ft Dry Containers)
- 2% are a mix of different other equipment types (20HC, 20OT, 20RF, etc.)
- 40ft containers:
- 55% are 40HC (40ft High Cube Containers)
- 33% are 40DC (40ft Dry Containers)
- 7% are 40HC RF (40ft High Cube Reefer Containers)
- 5% are a mix of other equipment types (40RF, 40DC, 40FR, etc.)
- 20ft containers:
-
Why is the CAx higher than 50 while the port is currently experiencing a shortage?
The CAx indicates how many full containers were imported versus exported. It serves as a tool to understand the imbalance of container movements in a specific location during a particular week.
A high CAx value does not mean all those containers are available. The high number of imports could result from shipping companies trying to alleviate the shortage by sending more containers to that port.
Overall, the CAx reflects the ratio of incoming to outgoing containers. Its implications depend on the specific circumstances of each port.
