The latest daily chemical price update from GuideTrends highlights significant market movements across Basic Chemicals, Fine Chemicals, Energy, Plastics, and Rubber. Today's market showed renewed volatility in solvents, petrochemical feedstocks, and selected fine chemical intermediates. Products including Petroleum Jelly, Dichloromethane, WTI Crude Oil, and Hydrochloric Acid posted notable gains, while aromatics and several bulk solvents remained under pressure. This report summarizes daily, weekly, and monthly price changes to help procurement teams, traders, and chemical manufacturers monitor short-term fluctuations and identify broader market pricing trends.

Basic chemicals remained generally weak on May 27, with aromatics, alcohols, and solvent products continuing to face downward pressure amid cautious downstream purchasing activity. Acetone, Benzene, Ethyl acetate, and Phenol all recorded notable declines, while Hydrochloric acid and Hexane showed relatively strong rebounds. Despite weaker short-term trading sentiment, products including Lithium carbonate and Sulfur still maintained solid monthly gains, indicating that several upstream industrial chains remain supported by medium-term supply tightness.

Fine chemical markets displayed higher volatility compared with bulk chemicals. Petroleum jelly surged more than 10% as supply availability tightened, while Lauric acid also maintained firm upward momentum supported by feedstock cost strength. On the downside, Stearic acid experienced a sharp correction after previous gains, and Melamine continued to weaken amid sluggish downstream demand. PTMEG-linked products stabilized slightly after recent extreme volatility, suggesting short-term market sentiment may gradually normalize.

Energy markets rebounded moderately during today’s session. WTI crude oil climbed 4.44% following renewed concerns over global supply stability, while Anthracite prices remained elevated due to stronger regional demand. However, refined oil products such as Gasoline and Asphalt continued to show weaker short-term performance, reflecting cautious downstream consumption and fluctuating transportation fuel demand.

Plastic and rubber markets remained relatively stable overall, though most mainstream resins continued to face mild downward pressure. ABS and EVA both extended their weekly declines due to weaker downstream manufacturing demand. In contrast, POM recorded a moderate rebound, supported by improved spot transactions and tighter supply circulation. Silica prices remained largely stable with limited short-term volatility across the rubber additives 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 27, 2026, based on the latest available trading activity and market feedback collected by GuideTrends market analysts.
