Spot rates from Shanghai Containerised Freight Index (SCFI) fell 8.3 percent to US$1,057 per TEU on the Asia-North Europe route on Friday, making it the second straight week of declines, Reuters reports.

Asia-Mediterranean rates fell 3.8 percent, but increased 13.3 percent to the US west coast and rose 6.2 percent to the US east coast, rising to $4,978 per FEU, a level not seen in more than a year.

After reporting a 13 percent increase in box volumes, Georgia Ports Authority executive director Curtis Foltz said: "Quite a bit of that is diverted."

Spot rates on the Shanghai-US west coast routes also showed solid increases during the week, adding $263 to reach $2,242 per FEU.
