News on December 31st: On December 31st, the bidding and sales situation of some domestic butadiene enterprises: Shenghong Refining reduced by 100 yuan/ton, executing 8400 yuan/ton; Yantai Wanhua started bidding with 84 tons at a price of 8200 yuan/ton, with transactions at 8340-8360 yuan/ton; Satellite Chemical executed 8400 yuan/ton. Supported by favorable fundamentals, the short-term trend of butadiene is relatively strong, and it is necessary to focus on downstream procurement. Chempricehub's analysis of butadiene, with a bullish-bearish score: 1.5. The article shows that Shenghong Refining reduced the butadiene price by 100 yuan/ton to 8400 yuan/ton, which may reflect adjustments in the company's sales strategy. However, Yantai Wanhua's starting bid of 8200 yuan/ton resulted in transactions at 8340-8360 yuan/ton, higher than the starting bid, and Satellite Chemical executed 8400 yuan/ton, indicating active market buying interest and strong demand. Supported by favorable fundamentals, if downstream procurement increases or supply tightens, the short-term trend will be relatively strong. This situation constitutes a strong positive for spot butadiene prices, and it is expected that short-term prices may rise or remain stable. Continuous attention to downstream procurement dynamics is needed to confirm the sustainability of the trend.
