Container traffic gives us an idea about the volume of goods being exported and imported - and possibly some hints about the trade report for December 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 unchanged compared to the rolling 12 months ending in November. Outbound traffic was down 1.0% compared to 12 months ending in November.
Inbound traffic has been increasing, and outbound traffic has been mostly moving sideways (down a little recently).
The 2nd graph is the monthly data (with a strong seasonal pattern for imports).
Imports were unchanged year-over-year in December, exports were down 11% year-over-year.
Exports suggest a slowdown in Asia, but import traffic was decent considering the ongoing labor negotiations. Hopefully the negotiations will be settled soon.
