Drewry’s composite World Container Index rose 2% this week to $4,639 per 40foot container. Rates on major lanes including Shanghai–Rotterdam, Shanghai–Genoa and Shanghai–Los Angeles increased by 2%–5%, while some return routes were flat or slightly lower, according to Drewry Supply Chain Advisors. The data points to continued increases in global ocean shipping costs. That trend adds upward pressure on import costs for primary commodities that rely on sea freight.
