Three signals converged in the resin market this week — and they all point in the same direction for buyers. 

WTI crude dropped 9%+ on the U.S.-Iran peace agreement. Polyethylene posted its biggest inventory build in 11 years. And benzene, the key feedstock for PA6, PA66, ABS, and PC, settled at a multi-year high for June — but spot has already reverted to the $3s, setting up a July inflection point. 

In this live AMA session, ResinSmart's Michael Workman is joined by Directors of Procurement Tyler Wheeler (engineered resins) and Kevin Mekaru (commodity resins) for an unscripted, data-first breakdown of what moved and what to do about it. 

What they covered: 

• PE inventory up HUGE — the biggest 11-year build. Producer asks have no data support. 
• PP: PGP softening into the mid-30s. 3-cent June ask is not legitimate. 
• PS: The one commodity resin where modest increases ARE warranted. Here's the benzene math. 
• PVC: 4-cent ask vs. an 8-month low in housing starts. How to use construction data in negotiations. 
• Engineered resins: How to read the benzene-to-resin price lag — and when July settlement triggers the rollback conversation. 
• POM/Acetal: Why this market is producer-channel-managed, and what that means for your pricing. 
• Live Q&A: PA66 supply risk from Celanese capacity cuts. 

Fuel surcharge timing. EPR legislation and PET. Additive market outlook. 

Kevin's closing note: "The signals are on the downward side. Understand what's signal and what's noise." Tyler's closing: "Relief is on the way. If you've been keeping score, you're about to have a healthy procurement pipeline."
