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 3.7% in May compared to the rolling 12 months ending in April. Outbound traffic was up 0.2% compared to the rolling 12 months ending the previous month.
The 2nd graph is the monthly data (with a strong seasonal pattern for imports).
2021 has started off incredibly strong for imports.
Imports were up 58% YoY in May (collapsed last year due to pandemic), and exports were up 2.6% YoY.
