Drewry World Container Index fell 3.22 per cent to $2,192 per FEU on April 17 due to weak demand and trade uncertainty from tariff tensions.
Freight rates dropped across major routes, notably Shanghai to New York and Los Angeles.
YTD rates averaged $2,897, slightly above the 10-year average.
Drewry anticipates further declines amid reduced capacity and ongoing disruptions from US trade policy.
