Report Industry Investment Rating - The investment rating for the synthetic rubber industry is "Bearish Oscillation" [3] Core Viewpoint of the Report - International crude oil prices have been declining, and the price of BR (Butadiene Rubber) has been consolidating. The supply of butadiene is affected by various factors such as device shutdowns and restarts, and the demand for rubber tires is relatively stable. The inventory of butadiene and BR has increased, and the profit of the rubber industry is under pressure. Geopolitical factors also have a negative impact on the market. Overall, the market for butadiene rubber is expected to be bearish with oscillations [3] Summary by Relevant Catalogs 1. Market Review - The price of high - cis butadiene rubber of Sinopec and PetroChina sales companies decreased by 300 - 400 yuan/ton this period. As of August 7, 2025, the mainstream ex - factory price of high - cis butadiene rubber in China was 11,500 - 11,600 yuan/ton [4] 2. Supply Analysis - **Butadiene**: Last week, the domestic butadiene production was 102,500 tons (-0.87%), with a capacity utilization rate of 69.76%. Some devices such as Nanjing Chengzhi, Sierbang, Yanshan Petrochemical, and Dongming Petrochemical were shut down, while some devices were restarted. The overall production decreased [3] - **Butadiene Rubber**: In July, some butadiene rubber devices were shut down, and some were restarted. It is expected that the production of butadiene rubber will continue to increase in August [3] 3. Demand Analysis - **Semi - steel Tires**: The replacement market price has no obvious adjustment this period. Some brands launched special - price patterns at the beginning of the month, and the actual market price is stable [3] - **All - steel Tires**: In August, the market price is mostly stable. Some brands planned to raise prices, but other enterprises did not follow up. The economic tire specifications are in short supply, and the inventory of mid - to high - end products is relatively sufficient [3] 4. Inventory Analysis - **Butadiene**: Last week, the port inventory of butadiene was 14,700 tons, a month - on - month increase of 41.35%. The overall inventory of enterprises has little fluctuation, and there is no obvious inventory pressure recently [3] - **Butadiene Rubber**: The inventory of sample production enterprises increased, and the inventory of sample trading enterprises decreased slightly this period [3] 5. Basis, Spread/Price Ratio, and Profit Analysis - **Basis**: The basis of butadiene rubber in North China is - 115 yuan/ton, in East China is 35 yuan/ton, and in South China is 35 yuan/ton [3] - **Spread/Price Ratio**: The RU - BR spread is 4,035 yuan/ton (41.33%), the NR - BR spread is 890 yuan/ton (23.61%), and the BR - SC price ratio is 0.97% [3] - **Profit**: The production profit of butadiene oxidation dehydrogenation and carbon four extraction, as well as the production profit and gross profit margin of butadiene rubber, are all under pressure [3] 6. Geopolitical and Macroeconomic Factors - OPEC + plans to increase production by 547,000 barrels per day in September, which leads to a loose supply of crude oil and a weak demand in the refined oil market. International oil and gas prices are oscillating downward. Trump signed an executive order to increase tariffs on Indian goods exported to the US, and the Sino - US tariff negotiation is approaching [3] 7. Investment and Trading Strategies - **Investment Viewpoint**: The maintenance of devices in Shandong and South China has a positive impact on the supply price of butadiene, but the short - term price change is small. The fundamentals of butadiene rubber remain the same, with traders reducing inventory and factories increasing inventory. The overall inventory level changes little, and the market trading volume is average [3] - **Trading Strategy**: For unilateral trading, it is expected to be oscillating. For arbitrage, pay attention to the strategy of going long on BR and short on NR/RU. Risks to be concerned about include downstream demand, cost changes, device maintenance, and geopolitical factors [3]
