On January 15, the bidding and sales situation of some domestic butadiene enterprises: Shenghong Refining & Chemical executed at 9,200 yuan/ton; Yantai Wanhua started bidding for 196 tons at 9,200 yuan/ton; Satellite Chemical raised by 200 yuan/ton, executing at 9,400 yuan/ton. Recently, both domestic and international butadiene prices have surged, with the main downstream synthetic rubber market also strengthening, forming an upstream-downstream linkage upward pattern. Although some downstream sectors have seen their profit margins continuously narrow due to the rapid rise in raw material costs, leading to cautious procurement, the core support logic of butadiene's short-term supply and demand fundamentals remains solid. PriceSeek analysis of butadiene, bullish-bearish score: 1.5. The article shows that butadiene spot prices continue to rise, with Shenghong Refining & Chemical and Yantai Wanhua bidding at 9,200 yuan/ton, and Satellite Chemical raising by 200 yuan/ton to 9,400 yuan/ton. Both domestic and international prices have surged. The downstream synthetic rubber market has strengthened simultaneously, forming an upstream-downstream linkage pattern. Although some downstream sectors have narrowed profit margins, leading to cautious procurement, the short-term supply and demand fundamentals of butadiene remain solid, with tight supply and resilient demand driving prices upward. This is favorable for spot prices, with a score of 1.5 indicating a generally positive outlook, as the upward price trend is clear, but downstream caution may bring short-term fluctuations. Synthetic rubber, bullish-bearish score: 1. As the main downstream product of butadiene, the article points out that the synthetic rubber market has strengthened simultaneously, forming a linkage upward pattern with upstream butadiene prices. Although the rising cost of butadiene has narrowed the profit margins of some downstream sectors and led to cautious procurement, the demand for synthetic rubber itself supports the market's strength, indicating a robust industry fundamental. This is favorable for spot prices, with a score of 1 indicating a generally positive outlook, as the market's upward trend is driven by upstream costs, but profit pressure may limit the extent of the increase.
