Polyethylene, the world’s most common plastic, surged to a near four-year high in March as the war in Iran pushed oil prices toward $100 a barrel, tightening feedstock supply and squeezing industrial users.
“This is different than anything we’ve seen for the world, for the North American market,” said Joel Morales, vice president of polyolefins Americas at Chemical Market Analytics, describing the market as “historic.”
The price of polyethylene has risen about twice as much as historical trends relative to oil would predict since the conflict began. While a typical $10 rise in oil adds about five cents per pound to polyethylene, the geopolitical risk premium has widened that spread. S&P Global analysts expect Brent crude to remain around $100 a barrel for the rest of the year.
The sustained high costs are creating a sharp divergence in the market, boosting profits for low-cost producers while threatening the solvency of smaller plastic converters. For consumer giants like Procter & Gamble, the new environment could erase its expected annual earnings growth, representing a potential $1 billion after-tax headwind.
The fallout from soaring plastic resin costs is rippling through the consumer goods sector, where packaging is an immediate and significant expense. Companies that rely heavily on polyethylene for products and packaging are facing significant margin compression. Since the start of the Iran war, the Vanguard Consumer Staples ETF (VDC) has fallen 5.7 percent, sharply underperforming the S&P 500’s 7.6 percent gain over the same period.
This pressure is particularly acute for private plastic converters, the companies that transform raw resin into finished products like bottles and packaging. These firms often lack the scale to absorb higher input costs or pass them on to large customers. According to James Gellert, executive chairman of financial analytics firm RapidRatings International, many are turning to credit to bridge the gap, increasing default risk in private credit portfolios. An analysis by investment bank advisor Lincoln International found that “shadow defaults,” which include distressed restructurings, have more than doubled in recent years.
North American Producers Gain Advantage
While users of plastic are struggling, North American producers that use ethane from cheap natural gas as a feedstock are seeing a significant financial benefit. Companies like Dow Inc. and LyondellBasell Industries NV have seen their shares mark 52-week highs since the war began.
“The model is, you let the guy in Asia, Europe and South America who has to use oil to make plastics, they set the price,” Morales said. “And then, if you’re a low-cost producer, you just sell at that price and make money.” For these producers, the combination of lower feedstock costs and globally elevated prices driven by oil means that recent price increases are translating directly into pure margin.
The dynamic is expected to continue as long as geopolitical tensions keep oil prices elevated. While the potential for demand destruction could eventually place a ceiling on how high plastic prices can go, the current supply-demand imbalance makes it difficult for most companies to avoid the higher costs.
