Based on the delivery price in the central Shandong region, today’s closing price was 14,175 yuan/ton, up 475 yuan/ton week-on-week. Domestic butadiene market prices rose today. In the morning session, market sentiment strengthened as major downstream synthetic rubber prices trended upward, supporting firm quoting intentions among traders. The bullish atmosphere continued into the afternoon, with traders raising their quotes and actual transaction prices increasing. However, downstream buyers’ willingness to chase high-priced butadiene remained moderate, creating resistance to transactions at elevated levels. Delivery prices in central Shandong ranged from 14,100 to 14,250 yuan/ton, while self-pickup prices for tank trucks in East China referenced 13,850 to 13,950 yuan/ton.

On October 8, the domestic butadiene industry capacity utilization rate was 69.97%, a slight decrease of 0.58 percentage points from the previous business day. Regarding theoretical production margins, on October 7, Japanese naphtha prices rose, while Sinopec maintained its butadiene price at 13,500 yuan/ton. Consequently, the theoretical production margin for butadiene via C4 extraction declined, calculated at 3,999.73 yuan/ton for the C4 extraction process.

4. Price Forecast

In the short term, Yangzi Petrochemical’s butadiene unit has resumed normal operation, and there are expectations for the restart of the Hainan Refining & Chemical unit. This suggests a potential increase in domestic supply, though its impact on market direction is limited. With crude oil and naphtha prices remaining at high levels, cost-side support for butadiene remains strong, reducing traders’ willingness to sell at low prices. Meanwhile, downstream enterprises maintain cautious buying sentiment, which may exert some pressure on market trends. The domestic butadiene market is expected to fluctuate within a range.
