WTI crude surged over 5% last week, peaked just shy of $84 a barrel on Strait of Hormuz shipping disruptions, then pulled back to $81 by Thursday. The reversal was real.
But the August benzene contract had already settled before the relief came. For polystyrene, ABS, polycarbonate, PA66, and PA6 buyers, the aftershock landed mid-week and it doesn't go backwards because crude came off its highs.
In this episode, Michael Workman walks through every major resin market — where supply is long and leverage is real, where the benzene settlement changed the cost picture, and the one active price increase in the market right now and why caprolactam is the data point every PA6 buyer needs before responding to anything.
What's covered this episode:
The crude oil and benzene story — WTI peaked just shy of $84/bbl on Strait of Hormuz disruptions before pulling back to $81 by Thursday on weak demand data and a large U.S. domestic stockpile build. Why the partial crude reversal didn't undo the August benzene settlement — and what that means for buyers in benzene-linked resins.
The two-track market — PE, PP, PVC, and PET buyers remain in a supply-long environment with no August price increase initiatives. Benzene-linked resin buyers woke up to a different cost conversation mid-week.
PE — ResinSmart is tracking a fourth consecutive monthly inventory build. Producers seeking 5 cents per pound for August to recover a portion of July's 10-cent decline. The supply data doesn't support it.
PP — No August initiatives announced. August pricing will follow the PGP settlement. Brief PDH flaring at Invista resolved by week's end — noise, not a signal.
PVC — Third consecutive monthly inventory build. No August initiatives. Construction demand still soft. Buyers hold the leverage.
PET — No announced increases. PX and PTA costs expected to provide a firmer floor following July's 3-cent decline. Seasonal bottle demand below expectations. Gulf Coast weather remains the watch point through end of summer.
PS — Where the aftershock hit hardest. Producers have a cost foundation for 5–11 cents per pound increase initiatives that they didn't have last month. Material availability remains comfortable, so full implementation isn't guaranteed — but the window to use July contract data as the primary reference is now, not later in August.
ABS and PC — No announced initiatives despite higher benzene. Higher costs are creating a floor against additional downward movement. Activity expected in Q4.
PA66 — Higher benzene partially offset by a lower August butadiene contract. No new initiatives. Mixed feedstock signals point toward status quo near-term.
PA6 — The one active increase in the market. One supplier announced 12 cents per pound citing higher benzene and sulfur costs. Caprolactam — the direct PA6 precursor — moved lower this week while benzene moved higher. A producer citing benzene as the cost driver needs to explain the caprolactam direction. That divergence is the buyer's negotiating lever.
Key market data referenced:
- WTI Crude: Peaked just shy of $84/bbl intraweek; settled near $81/bbl
- August benzene contract: Settled substantially higher vs. July
- PE: Fourth consecutive monthly inventory build; producer ask of 5¢/lb for August
- PP: No August initiatives; PGP as primary contract driver
- PVC: Third consecutive monthly inventory build; no August initiatives
- PA6: One supplier announced 12¢/lb August increase
- Caprolactam: Moved lower this week despite benzene gains
