Polymer-grade propylene (PGP) prices in the United States began the week on a weaker footing, easing lower as market activity remained sluggish. Spot PGP delivered to the US Gulf was assessed on Monday at 31.50–32.00 cents per pound, marking a decline of one cent per pound from last Friday’s levels.
An industry source in the US, speaking on condition of anonymity, attributed the dip to lackluster buying interest and thin trading volumes. “Spot PGP prices fell due to a weak trading momentum and subdued demand conditions,” the source explained, noting that downstream buyers were content to wait for clearer signals before re-entering the market.
In contrast, refinery-grade propylene held steady, with spot delivered prices assessed unchanged at 28.50–29.00 cents per pound FD US Gulf, reflecting balanced supply and demand at the lower end of the value chain.
The mild pullback in polymer-grade values highlights the cautious sentiment shaping the US olefins market as participants monitor feedstock trends and downstream production rates while moving into the final quarter of 2025.
