PriceSeek analysis of caustic soda, long-short score: -1. The article indicates that the spot price of 32% ion-membrane caustic soda at Shandong Luxi Chemical was lowered to 600 yuan/ton, and the 400,000-ton/year chlor-alkali plant operated normally, suggesting sufficient and potentially increasing market supply, which exerts downward pressure on the spot price of caustic soda. Combined with caustic soda futures data, recent contracts such as 2605 closed at 2,219 yuan/ton (up 38 yuan), indicating a short-term upward trend. However, the spot price reduction may signal bearish sentiment, affecting futures market expectations and putting future prices under pressure. Score: -1 (generally bearish), as the spot price reduction directly reflects loose supply and demand. Although futures data show short-term positive signals, the news reinforces the risk of oversupply.
