The main contract for synthetic rubber BR2509 closed at 11,785 yuan/ton, an increase of 2.48% compared to the previous day's settlement price. On the cost side, the Maoming Petrochemical butadiene unit is restarting, and Fushun Petrochemical plans maintenance, while Jilin Petrochemical is in the commissioning phase, indicating a potentially ample domestic supply. Additionally, port inventories remain relatively low, with expected concentrated imports arriving in late August, limiting the downside for butadiene in the short term. Supply-side dynamics show a mix of unit restarts and maintenance, with a slight expected increase in styrene-butadiene rubber supply and limited inventory depletion. Demand-side pressures persist, particularly for semi-steel tires, which maintain high inventory levels, complicating production rate increases. Overall, while the cost side has limited downside, the supply-demand balance for BR remains loose, suggesting a wide fluctuation in prices [5]
