US rail data for chemicals remain at the 5-year highs and have been there for almost 2 months. This is working its way into the supply chain and we are seeing weakness in US polymer prices across the board, except for PVC. US spot polymer prices are in a bit of a “no man's land” right now as they would need to drop significantly to find incremental demand offshore, given US premiums to the rest of the world. We believe that most of the volume leaving the US is doing so within company-specific businesses – ExxonMobil supplying ExxonMobil customers, Dow supplying Dow customers, etc, and consequently, these shipments do not show up in the spot market.
The concerns about supply chain inflation hurting chemical demand are likely very end-use specific. While the packagers and consumer goods sellers are seeing significant inflation in all raw materials, not just polymers, the packaging is a minor component of the cost and value of what they are selling and while it may hurt their earnings, it is unlikely to stifle demand – none of us is likely to stop buying milk, orange juice or cookies if the prices rise a couple of cents because the manufacturers are trying to cover some of their higher costs.
