On January 9, the bidding and sales situation of some domestic butadiene enterprises: Shenghong Refining executed 9,300 yuan/ton; Yantai Wanhua sold 140 tons externally, with a starting bid of 9,200 yuan/ton; Satellite Chemical reduced by 100 yuan/ton, executing 9,200 yuan/ton. Domestic butadiene is expected to maintain a strong trend in the short term, with recent synchronized strength in both upstream and downstream products in the industrial chain. The futures and spot performance of downstream synthetic rubber has provided a significant boost to the butadiene market. Although some downstream players are cautious about high-priced inquiries, as domestic supply-side and international prices rise, it is difficult to supplement the market with low-priced sources. It is expected that the domestic butadiene market will maintain a strong trend in the short term, with close attention needed on downstream transaction conditions. PriceSeek analysis of butadiene, bullish-bearish score: +1.5. Butadiene spot prices are supported by the futures and spot performance of downstream synthetic rubber, with enterprise execution prices at a high range of 9,200–9,300 yuan/ton (e.g., Shenghong Refining at 9,300 yuan/ton, Satellite Chemical at 9,200 yuan/ton), and Yantai Wanhua's starting bid at 9,200 yuan/ton. The synchronized strength in both upstream and downstream of the industrial chain, coupled with scarce low-priced sources due to rising supply-side and international prices, suggests a short-term continuation of the strong trend. Although some downstream players are cautious about high-priced inquiries, requiring close attention to transaction conditions, overall favorable factors dominate, resulting in a score of +1.5 (between generally favorable and significantly favorable).
