Founder Securities pointed out that current oil and gas prices remain high, significantly transmitting cost effects to coal chemical industries, with chemical product prices driven up by oil prices. Coal chemical profits are expected to accelerate, and 2026 may be a year of performance rebound for the coal chemical industry. At the same time, under the logic of energy security, the alternative demand for coal as a &#34;ballast&#34; is increasing, coupled with the recovery of thermal power and the promotion of collaborative policies for electricity calculation, enhancing the interconnectivity between coal chemical and petrochemical downstream sectors. The rigid rise in energy costs is forcing optimization of industry chain efficiency and upgrading of asset structures.
