Rate assessment increased by 42 percent to $1,674 per 40-foot container on the Shanghai-Los Angeles route, by 19 percent to $2,151 on the Shanghai-New York route and by 39 percent to $1,826 on the Shanghai-Rotterdam route.

"Unpredictable freight rates are not a new phenomenon in the container industry; however, a major upheaval of supply like this is likely to cause extreme short-term price volatility. Shippers should expect increasing freight costs and tight allocation for several weeks at least," said Richard Heath, general manager of WCI.

"The Hanjin bankruptcy means a shock to the market – some of our shipper customers are making contingency plans and asked us to assess the impact of this on their supply chains," said Philip Damas, director at Drewry, which jointly owns WCI alongside Cleartrade Exchange.

The World Container Index assessed by Drewry tracks and documents the weekly changes in spot rates on 11 East-West routes.

The World Container Index is a weekly container pricing index based on actual agreed freight assessments reported by industry players in Asia, Europe and the U.S. and is not financed or backed by either shipper or carrier interests.
