Report Industry Investment Rating - Not provided Core Viewpoints - Due to the high supply of pure benzene both domestically and overseas, the inventory at East China ports has increased, and the profit of pure benzene is lower than the same period in previous years.

Although the recent rise in international oil prices may support the cost side, in the short term, the spot price of pure benzene is expected to fluctuate at a low level, and the upward space of BZ2603 futures may be restricted by the supply - demand contradiction [2].
