It is interesting to note the rapid rise in US propylene (and benzene) values as they follow propane and crude prices (propane is following crude because of its heating value and export opportunities). Ethylene is not moving as US natural gas is in surplus and is not following international natural gas prices. The US is surplus ethylene and derivatives, but we would expect to see ethylene and ethylene derivative prices jump up in the US if Europe is physically unable to make ethylene and derivatives or if the costs in Europe become so high that supplying incremental volumes from the US becomes even more compelling. For more see today's report titled "Into The Mystic – Ex-US Energy Price Surge Favors US Producers; Low Visibility Keeps Capex In Check".
The Navigator Gas announcement should not be a surprise as the ethylene export arbitrage reopened in the US in September (Exhibit below) and since the terminal opened there has been a demand for ethylene exports each time the numbers have made sense. There are ethylene consumers in Asia that are net short and will buy incremental volumes from the US when the price is right relative to local suppliers and there is incremental demand in countries and regions that appear to be in surplus, including Europe, where a buyer can leverage an import to try to push local prices lower. In China, some of the facilities that require either propane or ethane imports might be better off buying ethylene versus making it today, and this is certainly the case for naphtha importers, as we highlighted in our Weekly Catalyst report on Monday. Today a US exporter can buy spot ethylene in the US and deliver it to China for less than the cost of manufacture in China, before the cost of getting the local ethylene to any consumer that is not on site.
The US ethylene market strengthened slightly in early July, most likely because of supply disruptions as it is hard to see how domestic demand could improve from here. There is not much room to increase prices further if the export market is the balancing mechanism through July and August, as prices remain depressed in Asia and any arbitrage would close quickly if prices in the US moved any higher. Despite the rising NGL prices discussed in today's daily report and on Sunday, the US has plenty of margin left in ethylene, and prices could go lower if that is necessary to move additional volume. While we talk in the opening paragraph about increased inventories of finished goods in anticipation of the year-end holiday season and continued supply constraints, and how this is leading to a shortage of warehouse space, we suspect that everyone upstream of the finished good suppliers is also looking at adding or maintaining a larger inventory cushion than they have in recent years. We still believe that it is a tough call today as to whether you should sell surplus ethylene or store it as we head into hurricane season in the US.
The chart below focus on the ethylene cost curve and show that the US currently retains a distinct cost advantage despite escalating domestic feedstock costs. The current cost advantage in the US is sufficient to move ethylene derivatives into most markets profitably and while US spot prices for ethylene may not quite reflect the levels needed to stimulate exports today – US ethylene costs certainly do. The restart of the Nova unit in Louisiana may put some further downward on US ethylene prices but as we discussed yesterday, given the weather risks in 3Q it is an interesting dilemma today over whether you sell surplus ethylene or store it on the basis that spot prices will rise because of production outages – this time last year the “store it” decision would have been the right one as spot prices rose through 3Q.
The Baystar polyethylene start-up date is consistent with the guidance that the company has been providing for a while, but it still leaves the venture with an ethylene surplus until that time and while the ethylene has been placed, according to the company, the ethylene that it has displaced will likely keep some downward pressure on US ethylene pricing until the polymer plant starts up (all things being equal). Even when the polymer plant starts, the US is expected to have a net ethylene surplus and we would expect exports to continue and prices to reflect levels to make the exports possible.
