Container traffic gives us an idea about the volume of goods being exported and imported - and usually some hints about the trade report since LA area ports handle about 40% of the nation's container port traffic.
The following graphs are for inbound and outbound traffic at the ports of Los Angeles and Long Beach in TEUs (TEUs: 20-foot equivalent units or 20-foot-long cargo container).
To remove the strong seasonal component for inbound traffic, the first graph shows the rolling 12-month average.
On a rolling 12-month basis, inbound traffic was up 0.3% in February compared to the rolling 12 months ending in January. Outbound traffic was down 0.3% compared to the rolling 12 months ending the previous month.
The 2nd graph is the monthly data (with a strong seasonal pattern for imports).
As expected, there wasn't a dip in February this year with ships still backed up waiting to unload.
Imports were up 4% YoY in February, and exports were down 3% YoY.
This was record inbound traffic for the month of February.
