For those who are too young to remember, OxyChems’ 30-year comment is because the company owned ethylene capacity in the late 80s and early 90s and would have made more during that extreme ethylene peak. This is likely the most money that the stand-alone vinyls business has made. The strength in the PVC could see some reversal if the inflation pressure remains high and housing-related spending slows, but the strength in the caustic market could persist, regardless of economic growth because of structural shortages and the challenges with imports.
We note the polyethylene price nominations in the US, timed by some to coincide with earnings releases this week and next, and would remind clients that there is always price momentum in commodities, one way or another. In our view, the price increase moves aim to maintain directional momentum (upwards) while giving the polymer producers some cover should natural gas prices spike further. US ethane prices are now tracking natural gas more closely and have moved up meaningfully over the last few weeks, and US ethane-based ethylene margins have fallen around 80% since the start of the year, with at least half of that coming from cost increases. All polyethylene producers are integrated back to ethylene, and the price nominations will be attempts to recoup some of the cost increases. This is against a backdrop of still very strong polyethylene margins in the US, which although way off their 2021 highs remain much higher than in 2019 and 2020 and the longer-term average. This is covered in our Weekly Catalyst report each Monday. Ethylene margins are summarized in exhibit below and the chart shows the impact of higher costs in the US and falling spot ethylene prices as the US now has more surplus ethylene capacity and is looking for export homes for ethylene and easy to ship derivatives. As we have noted before, the jump in margins in Europe and Asia is because of extreme volatility in naphtha markets over the last couple of weeks. We would expect margins to be lower next week based on naphtha moves this week.
We noted in today's daily report the number of shutdowns that are taking place in Asia and in Europe as feedstock costs become unmanageable, and the assumption is that these units will restart when economics recover. This may not be the case as companies factor in the costs of operating smaller units in an emission-constrained world, and the decision to shut down for economic reasons today may be the final nail in the coffin for some older and generally less economic base chemical units. Many smaller facilities in China were built in the 80s and 90s and these might not come back online if there is no easy way to lower emissions, but the harder decisions will likely be in Europe.
With the rapid jump in international natural gas and oil prices, we would see very concerted efforts to raise basic chemicals and polymer prices in Europe and Asia and will have a positive knock-on effect for the US. In our weekly catalyst report on Monday, we showed that ethylene producers outside the US were all losing money, especially in Europe and Asia. Some European demand will already be lower, because of curtailed product exports to Russia and Ukraine, but producers will want to cover costs at a very minimum and consequently, will be trying to match price increases with cost increases and if possible do a bit better than that. All of this will create a greater margin umbrella for the US, and US exporters selling directly into international markets will see export margins step up and may see incremental opportunities to export more, assuming that the freight rates are not too onerous for incremental containers.
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 drop in US benzene pricing is likely a function of lower crude oil pricing and the overall impact this is having on oil product values. As the US has moved to much lighter ethylene feedstocks, the proportion of benzene that is coming from refining is overwhelming and alternative values for benzene or reformate in the gasoline pool are a strong driver of US and international pricing. Lower naphtha pricing for ethylene units outside the US will also hurt benzene values. By contrast, the stronger natural gas market – through the end of last week - supported ethane pricing in the US and we saw a step up in propane pricing – which have provided support for ethylene and propylene – also note that the analysis we published yesterday in the weekly catalyst suggests that the US can export ethylene to Asia at current prices – delivering ethylene into the region below current local costs. This should keep a floor under US ethylene pricing although any further decline in crude oil prices relative to US natural gas and NGLs will close this arbitrage.
We talk about the US producer’s pressure to keep polyethylene contract prices flat in October earlier in today's daily report but the exhibit below helps to show some of the potential longer-term consequences of that behavior. The desire to keep pricing high by the producers is obvious as they will continue to make outsized margins if they do and carry some of the good 3Q profitability into 4Q – it will still not be as good as 3Q as costs are up for ethylene and every polyethylene producer is integrated back to ethylene in the US. The large gap in pricing with Asia is declining, in part because Asia prices are at costs and costs as rising as crude oil prices strengthen.
The crack in US polypropylene prices is probably worth some comments as the polymer has shown extraordinary strength since the middle of last year, in the face of new capacity that was expected to push the US market into surplus. In the chart below we show that the spread over propylene has not fallen, but this is because propylene is falling lock-step with polypropylene for the most part. Those companies integrated back to PDH economics will see a significant margins squeeze as polymer prices fall while propane prices increase. We have written recently about a concern that lower auto production rates in the US will back up into parts and that this will impact materials. In the early days of the auto cutbacks, we assumed that the automakers and their suppliers would simply build inventory, with the expectation of a bounce-back in demand once the chip shortage was over. As the chip shortage has dragged on and become more significant, we have likely hit any limit of inventory build, and we are concerned that polypropylene pricing could collapse if auto-related demand does not recover quickly. While autos are not a dominant demand category for polypropylene the sector is certainly large enough to swing the polymer market from shortage to surplus. With the rise in propane prices and other ethylene feedstocks, polypropylene profits could fall meaningfully. See today's daily for more comments on the propane markets.
The chasm between US and Asia polyolefins prices remains wide, close to a 5-year high for polyethylene and setting new highs for polypropylene. The polyethylene arbitrage is not large enough to encourage US imports – first Exhibit below – largely because of the very high container rates from China.
The ACC May production data shows the very strong year on year production growth globally, with the US gains more muted than the rest of the world as the COVID production impact in May of 2020 was less severe in the US than in many other parts of the world, and the China growth has been further assisted by significant capacity additions since this time last year. It is interesting to note that on a year to date basis the US is still down year-on-year, which is the lingering impact of the winter storm on production and it reflects that there is not much space capacity in the US, given both the strong demand and the export economic advantage of lower feedstock costs. Despite the collapse in prices in Asia – very well reflected in Exhibit 1 in today's daily report – the US has enough margin to continue its derivative and ethylene exports.
