What is driving the rapid price surge in PGMEA and how long will it last?
PGMEA prices have spiked due to triple pressure: surging downstream demand from wafer fab expansions and AI-driven advanced packaging, rising feedstock costs from Middle East energy volatility, and geopolitical supply disruptions. Brent crude averaged USD 107/barrel in May 2026, pushing up naphtha and propylene oxide costs. Energy-intensive production in overseas plants adds further upward pressure. Domestic Chinese producers benefit from lower electricity costs, creating a cost advantage. The price rally from RMB 7,600 to 14,200/ton within months reflects genuine supply tightness rather than speculation. With Shin-Etsu withdrawing its full-year earnings forecast and logistics costs up 30-50% via Red Sea diversions, the cost push is broad-based and likely to persist through 2026.
