US ethylene prices have bounced off a low this week largely, in our view on the steep rise in natural gas and ethane. The drop in ethylene prices over the last couple of weeks signals an imbalance whereby production is more than enough to satisfy domestic demand and export demand. Export demand is limited by terminal capacity, and we have seen some domestic demand issues for polyethylene, not because of demand weakness, but because of export logistic bottlenecks, that are resulting in product (with homes to go to) backing up in the US ports. Given the timing of this build-up, we may see some higher end-quarter working capital from some of the chemical companies with sizeable export footprints for 1Q 2022. The sharp increase in US natural gas prices and the catch up that ethane has made to natural gas, should keep some upward pressure on spot ethylene prices if gas prices remain high. Propylene remains very supported by high propane prices.
One of the key messages from the World Petrochemical Conference is that it is not an oil shortage, it is a commodity shortage, and we show our key metals index (updated through February) again in the chart below. We will update this again at the end of March (when consistent data is available) and given what has happened to both lithium and nickel prices we would expect a jump in the March index.
