The Indicator is Baltic Dry Index.
The Baltic Dry Index (BDI) is a number issued daily by the London-based Baltic Exchange. The index provides an assessment of the price of moving the major raw materials by sea. It is an indicator that tells you the current state of Global trade.
Here's the Weekly Chart
As you can see in the chart above: Baltic Dry Index used to trade above 11000 in 2008 and it crashed to 650 post Lehman crisis. But when Global markets recovered, Baltic Dry Index did not recover much. It has been five years now and not much improvement has been seen. This year has been very bad for the index. It's down 50% YTD.
One question everyone seems to be asking: If there has been improvement in Global economic scenario, then why this indicator, which is not speculative, crashed this year. Something to think about 🙁
