Polymer Global Analysis

Resin To Riches: Weekly Plastic Market Insights

• General Thoughts: Polymer markets are shifting toward supply security economics amid logistics disruptions, feedstock shocks, and precautionary buying, which are shifting global trade flows and tightening global spot market liquidity.  
• Polyethylene (PE): An unpredictable Middle East conflict has already shifted global PE market fundamentals, positioning US producers for stronger 1H26 margins than consensus expected after likely bottom-of-the-cycle conditions in 4Q25.
• Polypropylene (PP): Hormuz disruption and propylene inflation are tightening PP availability and driving near-term price spikes, while PP-to-PGP spread compression is likely to pressure non-integrated production globally through 2026.
• Polyvinyl Chloride (PVC): Energy shocks, geopolitics, and policy shifts are steepening PVC cost curves globally, strengthening integrated US exporters while accelerating margin pressure and rationalization across higher-cost regions.
• Other Sector Developments: Middle East disruptions, rising global LPG and naphtha costs, and fragile feedstock logistics are steepening global polymer cost curves and forcing operating rate adjustments across high-cost regions globally.

Exhibit 1 – Chart of the Day: Global PP spot prices track crude cycles, though feedstock cost shocks amplify volatility.
