The Baltic Dry Index measures cost for cargoes of raw materials by sea. It was around 2,000 points in the beginning of 2006. It jumped to 12,000 in mid 2008. Since then it fell to 925. That is an unprecedented collapse of freight rates.
But its not only raw material transport which slumped. Yesterday I took this picture of a usually empty part of Hamburg harbor.

These are five perfectly good feeder ships, normally used to distribute oversea containers coming from China to the Baltics and up to the UK, Sweden and Norway. Now they are moored to dolphins in the middle of the river.
I pass the place quite often and I never saw more than one ship laying there except during Christmas week. But I used to have a book with a harbor picture taken at the same place during the Great Depression. It showed some 15 out-of-work ships moored there.
These feeder ship are owned by small investors through private closed funds sold by local banks here. While Greece and Japan own the big bulker fleets, German private funds dominate the worldwide container ship market with ownership of some 3,000+ ships.
Having these out of work, will hit the income of a lot of normal folks around me.
Those ships are the first big locally visible sign of the downturn I noticed here.
