Spot rates for shipping 40-foot containers from China to the North American east coast jumped 23% this past week, pushing the cost over $9,000 for the first time since the index was created. The big takeaway here is that capacity is probably tapped out into the west.

The Freightos Baltic Exchange Daily Index (FBXD) measures the average spot rates from China to the North American east and west coasts in the chart. The difference between the two rates — called the Panama Spread (FBXD.PANA) — gets its name from the canal most of the ships traverse to get to the eastern ports.The Panama Spread rarely gets above $1,500; this week it is close to $3,000.

The sharp increase in the rate differential was caused by the disproportionate rise of the price for shipping containers to the east coast ports compared to the west coast. Rates increased as well to the west last week, but by a much smaller amount — only 10%.

Shipping freight into the ports of Long Beach and Los Angeles is traditionally the fastest way of getting goods from China into the U.S. Most of those goods either hopped onto the rail or were transloaded into a warehouse in pre-pandemic times.

With demand continuing to make it difficult for companies to restore their inventory levels, a lot of the freight is bypassing the stop at the western warehouses and transloading to a domestic intermodal container or a 53-foot trailer to move inland via truck. Conditions in both of these modes support the idea that the limit has been reached on the amount of freight that can be handled from the west.

Intermodal spot rates are showing a cost around $11,000 to ship containers by rail from Los Angeles to New Jersey when in June of 2019 it cost around $3,200. Keep in mind these are spot rates and represent the most volatile sample of shipment rates, but are representative of the underlying market conditions.

Trucking capacity has seen some easing over the past few months as national tender rejection rates have slowly receded, but remain historically high. Rejection rates for loads moving more than 800 miles originating in Los Angeles increased back to just below 30% last week.
