Freight rates and charter durations for feeder containerships are coming under pressure following recent record levels, brokers report.

Clarksons Platou Securities said the sub-3,000-teu segment was the last of the containership segments to surge and see healthy term charter interest, and now it is the first to experience some elements of softness.

"Our container desk assesses six to 12-month charter rates for 2,500-teu vessels at $68,500 per day, down from last week's $70,000-per-day level and the peak in October of $73,000 per day," analysts Frode Morkedal and Omar Nokta said.
