氯碱日报：PVC驱动不足，关注宏观情绪-20250903

1. Report Industry Investment Rating - Not provided 2. Core Viewpoints of the Report - For PVC, the market has a weak supply - demand situation, with long - term supply pressure and low - level downstream demand. Attention should be paid to macro and cost - end impacts, and there is still room for profit compression in the chlor - alkali industry [3]. - For caustic soda, the spot price is stable with a slight increase. Although there are short - term transportation restrictions, the overall order situation in Shandong is acceptable. The cost support remains, and the chlor - alkali profit is at a medium level compared to the same period [4]. 3.

Market Analysis PVC - The PVC futures price stops falling and rebounds. Attention should be paid to the impacts from the macro and cost ends. The supply side has increased maintenance, and the operation rate has decreased month - on - month. However, many maintenance enterprises will resume this week, and the output may increase slightly. In the long - term, the supply - side pressure is still large. The downstream demand remains at a low level, and enterprises maintain just - in - time procurement. The export signing and delivery volume have decreased month - on - month. Affected by India's PVC import policy, the export is expected to be strong before September and weaken in the fourth quarter. The PVC social inventory continues to accumulate, and the absolute inventory value is high. The 09 contract has a large warehouse receipt pressure. The chlor - alkali profit still has room for compression, and the supply - demand situation remains weak [3]. Caustic Soda - The spot price of caustic soda is stable with a slight increase. In September 2025, the delivered price of liquid caustic soda orders of alumina enterprises in Guangxi has increased by 100 yuan/ton compared with last month. The chlor - alkali enterprises have increased maintenance, and the operation rate has decreased but is still at a high level in the same period. Affected by transportation restrictions during the parade, orders from other provinces in Shandong have stopped, and the in - province delivery volume may increase. The receiving price of the main downstream alumina factories in Shandong is mainly stable. Non - aluminum downstream has a fear of high - priced goods. As the peak season is approaching, the overall order backlog in Shandong is acceptable, but the external - province delivery has been suspended in the short - term due to transportation. Attention should be paid to the restocking rhythm of downstream during the "Golden September and Silver October" peak season and the production start - up rhythm of alumina in Guangxi. The electricity price in Shandong has increased slightly in September, the price of liquid chlorine is weak, and the cost support remains. The chlor - alkali profit is at a medium level in the same period [4]. Strategy PVC - Unilateral: Pay attention to macro sentiment. With weak supply - demand, be cautious about shorting at high levels [5]. - Inter - delivery: Reverse arbitrage for V01 - 05 at high levels [5]. - Inter - commodity: None [5]. Caustic Soda - Unilateral: Be cautiously bullish [5]. - Inter - delivery: Positive arbitrage for SH10 - 01 at low levels [5]. - Inter - commodity: None [5].
