If this commodity cycle has the same drivers as prior cycles, producers like LyondellBasell and others will make comments like “stronger of longer” until prices turn, and if history is any guide, that turn will catch everyone by surprise, and even if it does not, there is no upside for any producer in predicting its end. As with all commodities, markets are tight until they are not, and markets are long until they are not. If you look at the ethylene and propylene price movements in the exhibit below you can see the speed of change that is possible and while the slope may be less severe for polymers in both directions, it can still be abrupt. The worst-case for the US industry would be a step down in demand coincident with the rising natural gas trend. There is no evidence of demand weakness today, but there will not be until it is happening. The extraordinary incremental freight rates shown in Exhibit 1 of today's daily report, make it increasingly unlikely that anyone sitting on surplus polyethylene or polypropylene in Asia can exploit the regional price difference. When demand and sentiment around supply chains turn, we would expect this spot shipping rate to collapse also – but there is no sign of that today.

The exhibit above shows incremental price strength for both propylene and ethylene in the US to start the week. Both monomers are trading well above costs, and this suggests that the incremental buyers either have high value-added derivative sales opportunities or that the incremental buyer is a producer either trying to supplement production or to repay product that is owed to others.
