On June 4, the auction and sales situation of some domestic butadiene enterprises is as follows: Dongming Petrochemical offered 280 tons for external sale at a reserve price of 11,600 yuan/ton; Satellite Chemical offered 420 tons for external sale with a starting price of 11,600 yuan/ton. Downstream buyers are showing strong price suppression sentiment, leading to generally weak market transaction volumes. Spot supply at low prices remains scarce, while holders' quotations tend to be firm. Affected by the tug-of-war between bullish and bearish factors, butadiene prices experienced minor fluctuations. Given that the supply-demand fundamentals are unlikely to change significantly in the short term, the market is expected to maintain a range-bound fluctuation trend.
