The latest daily chemical price update from GuideTrends highlights continued volatility across Basic Chemicals, Fine Chemicals, Energy, Plastics, and Rubber. Today's market saw sharp rebounds in selected fine chemical intermediates including Lauric acid, Oleic acid, and Trichloroethylene, while several bulk chemicals and energy products faced renewed downward pressure. Products such as Anthracite, Hydrogen peroxide, and WTI Crude Oil posted notable declines during the session. This report summarizes daily, weekly, and monthly price movements to help chemical buyers, distributors, and manufacturers monitor short-term fluctuations and identify broader market pricing trends.

Basic chemical markets remained generally weak on May 28, with solvents, alcohols, and peroxide-related products continuing to face downward pressure amid cautious downstream purchasing activity. Acetone, Hydrogen peroxide, and Propylene glycol recorded relatively sharp declines, while Zinc oxide and Phosphoric Acid maintained stronger upward momentum. Despite softer short-term sentiment, several products including PET and Urea still showed stable medium-term fundamentals supported by selective replenishment demand.

Fine chemical markets displayed significantly stronger volatility compared with bulk chemicals. Lauric acid and Oleic acid both surged more than 12% amid tightening supply circulation and stronger feedstock costs, while Trichloroethylene also rebounded sharply following active downstream replenishment. PTMEG-linked products stabilized moderately after recent fluctuations, suggesting short-term market sentiment may gradually improve across selected specialty chemical chains.

Energy markets weakened during today’s session. WTI crude oil declined 5.32% amid renewed concerns over slowing global fuel demand and softer macroeconomic sentiment, while Anthracite prices corrected sharply after recent gains. Refined products including Kerosene and Asphalt also remained under pressure, reflecting cautious downstream purchasing activity and weaker transportation fuel consumption trends.
Plastic markets remained relatively stable overall, though mainstream engineering resins continued to face mild downward pressure. ABS and POM both extended recent declines due to cautious downstream manufacturing demand and weaker spot trading activity. HDPE prices remained comparatively stable with limited short-term volatility across the broader plastics market.

The above pricing data is compiled from multiple market channels including domestic ex-works quotations, distributor transaction references, port prices, and mainstream spot market assessments. All data was updated on May 28, 2026, based on the latest available trading activity and market feedback collected by GuideTrends market analysts.
