Port Data, Green Shoot or a Weed?
If you have been following port data you no doubt saw the large spike in March of both inbound and outbound volume, and then a bit of continuation in April and May. A lot of people, both mainstream media as well as bloggers, came out saying that this was a huge green shoot and a sign that things were improving for the global economy. The Macro Trader came out with this post (click here) where we explained that there is a lot of seasonal influence in shipping and without looking at it you are missing a huge part of the picture.
Looking at the data below is the chart for the month of March from 1995-2009 (click to enlarge). As you can see March is a historically strong month, in fact it is historically the strongest month of the year. So while we had a strong rebound in month to month data that was to be expected in March. What many commentators forgot to mention was the year over year numbers which were anything but impressive, being down -17.21% that same month, not exactly the definition of a green shoot.
March Data
So where are we now? Well after March we had slight increases in both April and May. Historically April is the second best month of the year, so again not very unexpected. In June we had a decline of -6.02%, and a year over year decline of -19.31% in total loaded volume. Looking at the chart below (click to enlarge) you can see that seasonality is easily seen in the data and that we are a ways off from a new move higher.

We looked in the dictionary of overused terms and negative numbers were not under the term “Green Shoots”, however when we looked under weeds the exact definition was “negative numbers.” OK, maybe that was a sad attempt at being funny but still the numbers are not pointing to a current increase in global shipping. To help smooth out the data and show the long term trend of shipping data here is a chart of total loaded along with a 12-month moving average (click to enlarge). As you can see we are still in a downtrend and it will take more then a few months of increased activity to show real improvement.
