Commodity chemical stocks plunged on Wednesday after the U.S. and Iran agreed to a two-week cease-fire, unwinding a rally built on geopolitical tensions. LyondellBasell Industries slumped 7.5%, Dow fell 5.1%, and CF Industries dropped 5.7% as the S&P 500 rose 2.5%.
Despite a recent surge in analyst upgrades, Wall Street remains cautious on the sector. None of the three companies have more than 32% of analysts covering them with a Buy rating, according to FactSet data, well below the 55% to 60% average for S&P 500 stocks.
The sell-off came after the stocks posted their best quarter ever, with Dow, Lyondell, and CF surging 78%, 86%, and 68%, respectively, in the first three months of 2026. The cease-fire news sent benchmark oil prices down 12% to below $97 a barrel, erasing a key driver of the chemical stocks' recent outperformance.
The de-escalation paves the way for the commodity chemical trade to unwind. The conflict had provided a temporary boost to an industry struggling with oversupply, by driving up oil prices and taking Middle Eastern chemical capacity offline. Reopening the Strait of Hormuz is expected to increase global fertilizer and chemical supply, putting further pressure on prices.
The recent conflict had given the chemical business a much-needed tailwind after years of weak demand and severe oversupply. The war drove up oil prices, giving producers like Dow and Lyondell a cost advantage as they use lower-cost natural gas for a majority of their products.
For fertilizer maker CF Industries, the disruption to the Strait of Hormuz was a direct benefit. With 25% to 35% of global fertilizer materials passing through the waterway, the conflict sparked a surge in fertilizer prices.
While President Trump's agreement to a cease-fire and assistance with traffic in the strait signals a return to normal, benchmark crude oil prices are still up roughly 25% from before the conflict began, which may cushion the blow for these companies.
