US Gulf Coast polymer-grade propylene prices increased significantly by 14.3% in January 2026, following rising costs for crude oil feedstock, supply interruptions, and strong downstream demand for polypropylene. The rise in oil prices, fuelled further by geopolitical tensions in the Strait of Hormuz, ratcheted up production costs and held shipping availability hostage. Added pressure came from late-month propane prices further inflating the propylene economics. On the demand side, solid automotive consumption, making up almost 29% of polypropylene consumption, lent support to domestic buyers, while PP spot prices advanced. Supply was constrained by numerous scheduled and unscheduled plant outages nationwide, along with disruptions at Bayport Polymers, BASF, Chevron Phillips, Enterprise Products Partners and prolonged maintenance at Eastman Chemical鈥檚 Longview site. Logistics delays at Houston Port dampen prompt spot availability.
Key Highlights
-
US Gulf polymer-grade propylene prices increased **.** MoM in January ****.
-
Rising crude oil and propane prices significantly lifted production costs of propylene.
-
Multiple plant disruptions tightened effective propylene supply across the US.
-
Steady automotive-led polypropylene demand supported higher spot prices.
-
Port congestion and tariff uncertainties reduced spot propylene availability and exports.
Polymer-grade propylene (PGP) prices in the US Gulf Coast were sharply higher (DEL) in January ****, up **.** month-on-month as a since higher feedstock costs, tightening supply, logistics鈥俤isruptions, and resilient downstream polypropylene (PP) demand investigated new market dynamics. The price hike mirrored increasing cost strains throughout the petrochemical value chain and a squeeze on the availability鈥俰n coastal market.
One of鈥倀he main reasons for the bullish trade in propylene was the steady increase in crude oil prices during January that greatly increased the costs of producing...
