The Baltic Exchange's dry bulk sea freight index, which monitors the shipping rates for vessels transporting dry commodities, declined by approximately 5.7% to settle at 2,022 points on Tuesday. This drop followed a significant 10.7% surge in the previous session, spurred by expectations of increased shipping costs due to forthcoming reciprocal US-China port fees. Specifically, the capesize index, associated with vessels that typically carry around 150,000-ton cargoes such as iron ore and coal, ended its three-day upwards trend, tumbling by about 11.4% to 3,007 points. This descent occurred just a day after marking its most substantial gain since July 11. Conversely, the panamax index, which represents carriers of 60,000-70,000 tons of coal or grain, rose slightly by 0.5% to 1,815 points, while the supramax index edged higher by 0.6% to reach 1,408 points.
