Drewry WCI dropped 2.70 per cent to $3,273 per FEU as of February 6, influenced by slow economic activity in China and higher shipping capacity.
Freight rates across various routes also saw reductions.
The index remains 68 per cent below its 2021 peak but is significantly higher than pre-pandemic levels.
Drewry anticipates a slight decrease in spot rates next week due to increased capacity.
