It's back to 2012/2013 for polyethylene, but with a potential twist. As we noted in today's daily report, international prices for polyethylene are being pushed up by oil prices, and even with higher prices in Asia, margins are still negative locally, which suggests that they will go higher. This margin umbrella is what generated windfall profits for US and Middle East producers in 2012, 2013, and half of 2014. The upward pressure remains high for international polyethylene prices because producers are not covering costs locally and in theory, the US should continue to benefit and we see domestic polyethylene prices rising again, both contract and spot. The risk for the US is local overcapacity of polyethylene and potential export challenges. The pricing arbitrage to export US polyethylene is huge and rising, but we are in a constrained trade world and we understand that export terminals are at capacity and warehouses are full. It is possible that the sharply lower US ethylene price is not just a function of new ethylene capacity, but also a function of integrated polyethylene producers choosing to limit production and looking for homes for the extra ethylene. If the polyethylene producers in the US try to push more volume domestically we could see local prices fall well below their export alternative – this is possible, but unlikely, in our view. Polypropylene does not have the same significant net export and the two plant closure in the US are likely enough to drive the price support that we are seeing this week.
We discuss recent historic highs reached in China to US container freight rates in our daily research today, and (absent Ida) we note that freight charges remain a major component in favor of US polymer price support. With current container rates so high, it is difficult for US consumers to get access to cheaper material from Asia, even if they are willing to try the untested grades in their equipment. Absent the freight extremes today, we would be much more definitive in declaring that the US's record spot/contract polyethylene price difference was unsustainable and would be corrected quickly. While there appear to be some surpluses of US polyethylene today, such that producers are testing the incremental export market, the same producers can hide behind the freight barrier as they make arguments to support domestic pricing. Some US buyers may be getting pricing relief because they have price mechanisms that partly reflect the spot price. It is also possible that large buyer discounts have risen through this period of very high pricing (this has happened before).
To put some perspective around the shipping container costs shown in Exhibit 1 of our daily report today, $20,000 per container equates to roughly 34 cents per pound of cargo assuming that the container is filled to maximum weight. If we also add in loading inefficiencies and assume 500 miles of road transport in the US or Europe, we can add another 5-10 cents per pound. Using ethylene costs in Asia at roughly 43 cents per pound as a basic benchmark (see our most recent weekly catalyst report), we thus estimate that it would cost around 90 cents per pound to get Asia polyethylene into the US. This does not include any working capital cost assumptions around ownership of the cargo from point of production to point of use. US spot PE prices are currently below 80 cents per pound for the more commodity grades of polyethylene, which is the market that could most easily be targeted by imports from Asia. When container rates were closer to $3000 per unit, the all-in import costs would have been roughly 30 cents per pound lower and the arbitrage would have been worth exploring. Of course, if the freight rate was only $3000 per container US polymer prices would likely be lower.
