US agricultural exports (corn soyabeans, grains, frozen pork, oilseeds etc) have surged 20% by weight in the 6 months ending Feb 29 according to the Dept of Agriculture. But facts on the ground, at railyards and ports suggest that without the shortage of containers the exports would be much higher. Ports are already congested and one shipping line based in Singapore is divering 10 of its 120 ships away from US ports. One agricultural commodities trader pays truckers to spend the night at railyards in the hope of picking up empty containers. And containers have to be sent hundreds of miles to where they are needed instead of being right nearby as used to be the case. Shipments of lentils and peas are being delayed by months. And in this situation cargo ship operators are raising prices.
