Recent Market Dynamics

• Benzene and Oil Prices

Intense competition arose from a significant capacity expansion in China’s petrochemical industry, leading oil and benzene prices to hit historical lows in Q4 2025.

Driven by the escalating conflict involving the U.S., Israel, and Iran, oil prices saw a sharp reversal. Benzene prices subsequently rebounded, supported by rising oil costs and strengthening downstream demand for styrene.

• Carbon Materials

China’s severe anode material overcapacity and rising economic uncertainty continue to dampen market conditions.

Benefiting from market opportunities in AI server BBUs and SiC semiconductors, we will see the growth potential for its advanced carbon materials and isotropic graphite blocks.
