The linked China polyethylene headline highlights a possible risk for US producers, as we link much of what is happening in China to logistic challenges. China has high production costs in a high oil environment, which is driving some of the cutbacks, but a portion is likely driven by an inability to move product and a huge disincentive to build inventory at break-even or negative margins. If the current shipping challenges in China roll over more aggressively into the rest of the world and container and vessel availability fall again, the US may face more challenges exporting polymers. As warehouse space fills, especially on the Gulf Coast, we may see some need to cut back rates, even if all of the material in storage currently has an agreed home and an agreed price. The US can afford to build inventory, as production costs still remain attractive relative to international prices, but if the supply chain is full there could be nowhere to put more material. One of Union Pacific's issues highlighted last week was too much inventory in rail cars, snarling up the system.
