BDI takes up cliff diving

I hadn't looked at the Baltic Dry Index (BDI) for several weeks, and not posted anything on it for several months, but just like the sea if you turn your back on it you will likely get smacked in the back of the head. Anyway it seems like it has fallen by over 50% in the last 3 weeks! Whilst some of this fall might be seasonal with global trade falling after ramping up prior to the year end holiday period, but any forward looking indicator halving in under a month can never be a good thing.
