Dry Bulk Freight Index
A composite index tracking the average cost of moving major dry-bulk cargoes by sea — a barometer of dry-bulk demand.
A dry-bulk freight index aggregates assessed freight rates across the main dry-bulk vessel classes (such as Capesize, Panamax and Supramax) into a single composite that tracks how expensive it is to move raw materials — iron ore, coal, grain — by sea.
Because dry-bulk shipping moves the inputs of heavy industry, the index is widely read as a real-economy demand signal. On TheMaritime we publish daily dry-bulk and tanker freight series under our own generic names.
