The Baltic Exchange’s dry bulk freight index, which tracks shipping rates for vessels transporting dry bulk commodities, declined for a second consecutive session on Tuesday, slipping about 1.8% to 2,670 points, pressured by weakness in the larger vessel segments. The capesize index, covering vessels that typically carry 150,000-ton cargoes such as iron ore and coal, fell around 3.5% to 3,911 points, while the panamax index, which reflects rates for ships transporting roughly 60,000 to 70,000 tons of coal or grain, decreased 1.1% to 2,266 points. In contrast, the supramax index rose 1.3% to 1,685 points.
