Chempricehub Analysis of Butadiene, Bull-Bear Score: +1.5 Sinopec raised the butadiene execution price by 200 yuan/ton to 8,300 yuan/ton, directly reflecting tight supply in the spot market and support from rigid demand. The three major factors—tight supply, stable downstream rigid demand, and external price linkage—continue to dominate. It is expected that prices will maintain a strong and volatile trend in the short term, benefiting the spot market. The score is +1.5 (neutral to significant positive), as the price increase is significant and short-term fundamentals provide strong support. However, close attention should be paid to downstream procurement conditions to confirm the sustainability of the upward trend.
