Container freight rates for voyages from Asia to the US have been on the rise over the past three weeks, thanks mostly due to better seasonal demand and reduced liner capacity, according to an analyst.

Rates for containers getting shipped from Asia to the US West Coast have improved 27.3% since 3 July to $1,539 per feu on Monday, while rates for boxes headed from Asia to the US East Coast have risen 10% to $2,609 per feu, according to the Baltic Exchange’s Freightos Baltic Index.
