According to a recent research report from KeyBanc Capital Markets, conflicts involving Iran could provide short-term advantages for US petrochemical producers, leading to a tightening of global supply and improving profit margins in key chemical markets. KeyBanc Securities research analyst Aleksey Yefremov stated that supply disruptions related to the conflict could impact a significant portion of global production capacity. This may drive up prices for polyethylene and related products in the coming months.
Yefremov wrote in a March 3rd report, "With approximately 11%–15% of global ethylene/polyethylene (PE) capacity directly affected by the US/Israel-Iran conflict, we are upgrading Dow Chemical and LyondellBasell to 'Overweight'." The analyst noted that rising crude oil prices are also shifting the global cost curve in favor of US producers reliant on natural gas feedstocks. As oil prices increase, the production costs for Asian naphtha-based facilities become more expensive, thereby widening the cost advantage for US ethane-based production plants.
KeyBanc anticipates that disruptions linked to Middle East tensions could temporarily reduce global polyethylene supply by approximately 5% to 10%. The generally low inventory levels across the petrochemical supply chain may amplify this effect as buyers rebuild their safety stocks. The firm's base-case scenario suggests US polyethylene prices could rise by about $0.10 per pound in the coming months. Under a more constrained supply scenario, the increase could exceed $0.15 per pound. The report indicates that spot export prices have already moved higher, with recent increases of about $0.12 to $0.15 per pound. If disruptions persist beyond a few weeks, the resulting supply tightness could last for several quarters before additional capacity comes online.
KeyBanc upgraded both Dow Chemical and LyondellBasell to "Overweight," citing their strong positions in the ethylene and polyethylene markets. The firm also raised earnings forecasts for both companies. For LyondellBasell, analysts now project 2026 EBITDA of approximately $3.78 billion, up from a previous forecast of $2.57 billion. Under the revised forecast, Dow Chemical is expected to generate about $4.09 billion in EBITDA for 2026, higher than the prior estimate of approximately $3.68 billion.
Other companies may experience mixed effects. Celanese could benefit from tightening in the methanol market, while Olin might gain from rising caustic soda and related chemical prices. Meanwhile, KeyBanc downgraded Avient to "Sector Weight." Analysts suggested that rising raw material costs could squeeze margins, as approximately 35% of the company's raw materials are hydrocarbon-based.
Geopolitical conflicts are also driving broader energy market volatility. Crude oil prices have climbed significantly in recent weeks. Higher oil prices tend to elevate the global ethylene cost curve, which benefits US producers using cheaper natural gas feedstocks. Simultaneously, transportation costs are rising due to war-related insurance premiums and supply chain disruptions. Container freight rates have increased, with some carriers announcing additional charges of $900 to $1,400 per 40-foot container on key Asia-to-Europe routes. If the conflict persists and shipping disruptions continue, freight rates may remain elevated, further tightening global petrochemical supply flows.
Despite price increases, KeyBanc does not anticipate a sharp decline in petrochemical demand. Many applications, including packaging, are considered essential and tend to be relatively insensitive to price hikes. Instead, analysts expect near-term market dynamics to be driven primarily by supply constraints rather than demand growth. As Yefremov noted, the current tightness in ethylene, polyethylene, and methanol markets is "supply-driven, not demand-driven," reflecting disruptions in production and logistics rather than a sudden surge in consumption.
