The Baltic Dry Index (BDI), is issued daily by the London-based Baltic Exchange. The BDI is a composite of the Capesize, Panamax and Supramax Timecharter Averages. It is reported around the world as a proxy for dry bulk shipping stocks as well as a general shipping market bellwether.
The BDI is the successor to the Baltic Freight Index (BFI) and came into operation on 1 November 1999. The BDI continues the established time series of the BFI, however, the voyages and vessels covered by the index have changed over time so caution should be exercised in assuming long term constancy of the data.
