Supply dislocations are unwinding and Chinese demand is weak, pointing to more downside for ethylene and polypropylene prices before new capacity adds to the glut.
Analysts expect petrochemical prices to keep falling as supply disruptions that drove a sharp rally begin to reverse and demand from China disappoints.
The run-up that pushed ethylene and propylene to multi-year highs was fuelled by plant outages in Europe and Asia and sanctions that rerouted Russian feedstock flows. Red Sea shipping delays added to the squeeze, stretching lead times and lifting freight costs. Those dislocations are unwinding. Idled crackers in South Korea and Taiwan have restarted. European buyers who paid a premium for alternative supply now see shorter lead times, and spot freight rates have come down. A trader at a Singapore-based petrochemical broker said the ethylene spot market has loosened noticeably over the past four weeks.
Demand from China, the world's largest consumer of basic petrochemicals, has not lived up to expectations. Construction and automotive sectors, two big end-users of polyethylene and polypropylene, show sluggish offtake. Chinese independent refineries have cut run rates, reducing output of petrochemical byproducts. One analyst at a consultancy covering the region said the second-quarter recovery many had expected never materialised.
New capacity is adding to the supply overhang. Saudi Arabia and the United States are both starting large integrated crackers and derivative units. US Gulf Coast expansions, tied to cheap ethane from shale gas, put downward pressure on export prices. In the Middle East, new propane dehydrogenation and polypropylene units are coming online into an already well-supplied market.
Feedstock costs have also weakened. Crude oil has traded in a narrower range this quarter, and naphtha prices in Asia have fallen more than 10% from their April peak. Cracker operators running on naphtha see thinner margins, though that has not yet triggered the kind of production cuts that would tighten supply. For context on feedstock costs, see the crude oil profile.
The margin squeeze is most acute in Europe, where gas-based costs remain higher than in the US or the Middle East. A European industry group said last week that operating rates at regional crackers had dipped below 80%.
