2. This week's market recap

Figure 1: 2023-2025 PS Daily East China Market Price Trend Chart (Unit: Yuan/Ton)

In the current cycle, domestic PS market prices have fallen by 40-150 yuan/ton, mainly influenced by the decline in styrene and market price reductions for sales. On the cost side, the continued drop in pure benzene and high inventory levels have led to a weak trend in styrene. On the supply and demand side, the restart and increased production capacity of some manufacturers in Shandong and Anhui have led to higher industry output, keeping supply at a high level. However, the overall recovery of downstream demand has fallen short of expectations, resulting in continued inventory accumulation. According to Longzhong Information data, on March 27, 2025, the transparent PS in the East China market fell by 150 to 8,400 yuan/ton, while the modified PS fell by 150 to 9,700 yuan/ton.

3. Next Week Market Forecast

The short-term PS market is expected to show weak fluctuations. On the cost side, there are still weak expectations for pure benzene, and the maintenance of styrene and the progress of inventory reduction are both slow, which may provide little support for costs. On the supply and demand side, industry supply continues to operate at high levels and has reached a historical high. The marginal effect of the "old-for-new" policy on domestic demand is weakening, export demand continues to be affected by tariffs, and overall downstream performance is below expectations, indicating a prevailing trend of loosening supply and demand.
