Friday saw a sharp selloff in chemical commodity stocks after Iran signaled the reopening of the Strait of Hormuz, increasing hopes for a ceasefire and the easing of supply disruptions. Dow Inc. (DOW) fell about 10%, LyondellBasell Industries (LYB) dropped 12%, and CF Industries (CF) lost 9%. Many viewed this as a straightforward unwind of the supply-shock premium, but the fundamentals for these companies may not shift as quickly as the headline move implies.
Strait Reopening Doesn't Instantly Restore Production
The Middle East remains the largest exporter of commodity chemicals globally, and much of the world's plastics supply is connected to this region. According to Trading Economics, polyethylene prices — the most commonly produced type of plastic — have risen 24% since late February, as the regional conflict intensified. This built a significant risk premium into the plastics market. While the reopening of the Strait could allow inventory at Persian Gulf ports to move, a Morningstar note from analyst Seth Goldstein explains that a large portion of Middle Eastern production capacity will remain offline in the near term. He wrote, “we still think a lot of production capacity in the Middle East will remain offline over the near term as liquid natural gas production, the feedstock for the building blocks ethylene and propylene, remains down. This should leave the global market undersupplied and near-term prices higher.”
This distinction — between moving inventory and full production recovery — is key. Even with ports accessible, actual chemical output from the region is likely to remain impaired while feedstock production remains constrained. Thus, the market's assumption of immediate normalization may not hold up, and prices could stay elevated for longer than a single market reaction implies.
Stocks365 Take: Dow's Feedstock Advantage Still Matters
Both Dow Inc. (DOW) and LyondellBasell have been seen by analysts as relative beneficiaries during the energy shock, due in part to their reliance on lower-cost North American natural gas liquids rather than Middle Eastern LNG feedstock. So even as the supply situation normalizes only gradually, these companies may retain certain cost advantages.
Key Variables to Watch for Chemical Commodities
Looking ahead to Monday, the main factors for chemical stocks are on-the-ground updates regarding LNG production capacity in the Persian Gulf. If production capacity does not recover promptly, the sharp selloff in Dow and LyondellBasell could appear overdone. On the other hand, an accelerated ceasefire agreement that enables a swift ramp-up in regional output could justify the market's response. For Dow in particular, with plastics accounting for over half of its business, ongoing supply tightness could continue to provide earnings support even as the initial shock fades.
The conclusion is that Friday's market reaction may have oversimplified what remains a complex regional supply situation. Investors should monitor physical production data closely, as the pace of actual recovery will likely determine how these names trade from here.
