The polypropylene chart below, shows just how much of an impact the polymer has on the “average” in Exhibit 1 from today's daily report. Polypropylene is the only large volume polymer that can afford the freight rates to move surpluses from Asia to the US today and while some material is moving, volumes remain limited by the high cost of shipping and some of the additional logistic hurdles getting truck-based materials to US consumers that generally take the product by rail. The very high polypropylene margin in the US is a function not only of very strong demand but also demand that is likely growing faster than expected, giving buyers little negotiating room to get materially lower pricing. A year-end inventory correction from polymer buyers might send prices lower more quickly, but we have yet to see much evidence. We remain surprised by the apparent demand for polypropylene in the US given the lower automotive throughputs in 2021.
The ICIS polypropylene analysis in the linked headline is interesting in that it shows the vulnerability of the traditional exporters of polypropylene to China if China goes ahead with the longer-term capacity announcements that local producers have made to date. The analysis suggests that this development will move China moves from deficit to surplus in PP.. Where the analysis may be wrong in our view is that the current high price of propane, low ethylene margins, and low local polypropylene margins could put portions of the planned capacity on hold, and while it may come eventually, the phasing of additions may be different. Current economics make any ethylene (and associated propylene) investments hard to justify and the same with PDH. In the past, we have seen China pull back investments when economics have not worked – most notably in the early part of the last decade when oil prices were very high. At that time China moved to projects based on coal, and while that may re-emerge, local oversupply, in general, will slow things down in our view, and pushing back towards coal may not fit with whatever carbon emission targets China will set ahead of the COP26 meeting.
The much higher polypropylene margins in the US come despite very high propylene pricing, and the whole chain did well in the first half of the year. Demand for polypropylene has been significantly stronger than most expected year to date, although production outages have helped the market, and what we had expected to be a surplus in the US in 2021, precipitated by the Braskem start-up has turned out to be production coming online just in time and prices might have been higher still had the Braskem plant not been there. We see some of the demand as cyclical - in response to consumer durables, though there has been lower use in the auto industry because of the production cutbacks. See more in today's daily report.
