Report Summary 1. Investment Rating - No investment rating is provided in the report. 2. Core View - The cost recently supports the offer price of butadiene rubber, but the supply will increase after the restart of maintenance devices. The negotiation focus of spot - end traders and downstream is divergent. The inventory of butadiene rubber sample enterprises increased slightly last week. Although some production devices were shut down for short - term maintenance, the price center of the spot end is low due to the downstream's wait - and - see sentiment and arbitrage resources. This week, with the co - existence of device maintenance and restart, the supply is expected to change little. Under the shipping pressure, the inventory of production enterprises is expected to decline slightly, while the inventory of trading enterprises is expected to increase. In terms of demand, the capacity utilization rate of domestic tire enterprises fluctuated slightly last week. The production capacity utilization rate of domestic tire enterprises may be slightly adjusted in the short term, with limited overall fluctuation space. The BR2509 contract is expected to fluctuate in the range of 11,680 - 12,200 [2]. 3.

Raw Materials and Spot Prices - As of August 11, the market price of butadiene in Shandong is 9500 yuan/ton, an increase of 125 yuan/ton; CIF price for butadiene in China is 1070 USD/ton, unchanged; the market price for styrene-butadiene rubber (BR9000) in Shandong Qilu Petrochemical is 11700 yuan/ton, with a price difference of -2880 yuan/ton and a basis of -85 yuan/ton [1] Production and Operating Rates - In July, China's butadiene production was 453,600 tons, a month-on-month increase of 3%; styrene-butadiene rubber production was 129,200 tons, a month-on-month increase of 5.5%; semi-steel tire production was 56.97 million units, a month-on-month decrease of 1.1%, but a year-on-year increase of 7.8%; full-steel tire production was 12.75 million units, a month-on-month increase of 1% and a year-on-year increase of 5.1% [2] - As of August 7, the operating rates in the styrene-butadiene rubber industry showed differentiation, with butadiene industry operating rate at 69.8%, a decrease of 0.3%; high-styrene butadiene rubber industry operating rate at 68.2%, a decrease of 5.9%; semi-steel tire sample manufacturers' operating rate at 69.7%, a decrease of 0.4%; full-steel tire sample manufacturers' operating rate at 60.1%, an increase of 1.3% [2] Inventory Levels - As of August 6, butadiene port inventory was 14,700 tons, an increase of 4,300 tons; styrene-butadiene rubber factory inventory was 24,150 tons, an increase of 350 tons, a month-on-month increase of 1.5%; traders' inventory was 7,290 tons, a decrease of 230 tons, a month-on-month decrease of 3.1% [3] Industry News - According to Longzhong Information on August 11, Qixiang Tengda's 90,000 tons/year high-styrene butadiene rubber unit has been shut down for maintenance since August 1 and is expected to restart soon; China National Petroleum Corporation's Jilin Petrochemical Company is currently in the commissioning phase of its 200,000 tons/year butadiene unit [4] Market Analysis - On August 11, commodity prices rose, with natural rubber strengthening, boosting BR prices. 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]
