While North America West Coast port volumes have started to contract sharply in Q32022 (both Y/Y and on an annualised basis compared to 2019), the same is not the case for the North America East Coast ports.

"As shown in Fig 1, the Y/Y laden inbound growth in Q32022 was between 4-11 percent, and the annualised growth was between 7-10 percent," says Sea-Intelligence in its latest update.

"Total handling volumes also exhibited a similar growth trend, albeit shifted slightly downwards. There is also an increase in the laden export volumes, growing Y/Y for four consecutive months in September, which shows that the carriers are starting to clear out the laden export backlog a little more.

"That said, empty exports are still growing at a rate of 17-20 percent Y/Y when annualised against 2019."

Another key takeaway - there is a continuing volume shift from the West Coast to the East Coast ports where handling volumes on either coast are closer to parity while in the past decade, North America West Coast ports have handled considerably more volumes than the East Coast ports.

"This is shown in figure 2 where a figure greater than 1 means more volumes are handled in the West Coast ports, and vice versa."
