Baltic Dry Index, Daily Update:
The Baltic Dry Index (BDI) is a shipping and trade index created by the London-based Baltic Exchange that measures changes in the cost to transport various raw materials. The exchange directly contacts shipping brokers to assess price levels for a given route, product to transport and time to delivery, or speed. The Baltic Dry Index is a composite of three subindices that measure different sizes of dry bulk carriers, or merchant ships: Capesize, Panamax and Supramax.
