1. Report Industry Investment Rating - The investment view of the synthetic rubber industry is "oscillating bearish" [2] 2. Core View of the Report - The domestic butadiene market has weakened slightly. Butadiene rubber is affected by macro - sentiment, and the market's attempt to support prices has been hindered. Under the pressure of high inventory and high production, the synthetic rubber market is viewed with a bearish attitude in the short - term. In terms of valuation, the correlation between the BR futures and NR has increased, showing stronger rubber - related attributes [2] 3. Summary According to Relevant Catalogs 3.1 Market Review - During the reporting period, the prices of high - cis butadiene rubber of Sinopec Chemical Marketing and major sales companies of PetroChina remained stable. As of September 25, 2025, the mainstream ex - factory price of high - cis butadiene rubber in China was between 11,700 - 11,800 yuan/ton. The temporary shutdown of Shandong Yihua's butadiene rubber plant due to a malfunction did not boost the supply in the short - term as the overall supply of private spot resources was sufficient, and there was an expectation of concentrated restart of maintenance plants at the end of September. The increase in external supply of butadiene led to a decline in the transaction center, and the cost side also lacked driving force. Although the mainstream supply price of butadiene rubber was lowered at the end of the previous period, the price centers of arbitrage resources and private resources in the first and middle of the week were still significantly lower than the spot cost of the two - oil resources. Some industry players were still waiting for a further decline in the mainstream supply price. In the middle and late weeks, the supply of low - priced arbitrage resources decreased, and the price gap between high - end and low - end spot narrowed slightly. As the pre - holiday stocking was coming to an end, downstream buyers continued to purchase on dips [3] 3.2 Supply and Demand Analysis 3.2.1 Supply - **Butadiene**: Last week, the domestic butadiene production was 103,000 tons (-1.91%), and the capacity utilization rate was 66.3%. Devices such as Nanjing Chengzhi, Sierbang, Yanshan Petrochemical, Dongming Petrochemical, Jilin Petrochemical Phase I, Fushun Petrochemical, and Fujian Refining & Petrochemical's No.1 unit remained shut down, and production continued to decline [2] - **Butadiene Rubber**: The butadiene rubber plants of Shandong Weite, Taiyo - Yuubu, and Haopu New Materials continued maintenance. Shandong Yihua's plant was shut down temporarily due to a malfunction. The production and capacity utilization rate of high - cis butadiene rubber decreased [2] 3.2.2 Demand - **Semi - steel Tires**: During the period, the market trading was dull. In some regions, the sales of all - season tires were weak, the social inventory was sufficient and the consumption was slow, so agents were not active in purchasing. For the snow - tire market, product promotion meetings of various brands were held one after another, and the channel inventory was relatively sufficient. Future attention should be paid to the terminal demand [2] - **All - steel Tires**: During the period, the market trading was average, mainly for regular sales, and the transaction price was stable. There was no obvious pre - holiday stocking, and the inventory was mainly consumed during the period. It is expected that the market stocking volume will increase significantly in the next period [2] 3.3 Inventory Analysis - **Butadiene**: Last week, the butadiene port inventory was 277,500 tons, a week - on - week increase of 20.13%. Some devices continued to operate at reduced capacity, the refinery inventory decreased, and the suppliers sold more goods before the holiday, so the inventory remained at a relatively low level. The port inventory increased significantly due to the arrival of ocean - going vessels during the week, but there was no obvious short - term inventory pressure [2] - **Butadiene Rubber**: The inventory of high - cis butadiene rubber enterprises + traders was 32,300 tons, a week - on - week decrease of 4.21%. The inventory of sample production enterprises increased slightly, while the inventory of sample trading enterprises decreased [2] 3.4 Price and Spread Analysis - **Price**: The prices of high - cis butadiene rubber of major enterprises remained stable during the period, but most prices showed a week - on - week downward trend. For example, the ex - factory price of Sinopec's North China Qilu, North China Yanshan, East China Yangzi, and South China Maoming decreased by 200 yuan/ton week - on - week [7][8] - **Spread/Price Ratio**: The RU - BR spread was 4,040 yuan/ton (-1.22%); the NR - BR spread was 1,005 yuan/ton (+17.54%); the BR - SC price ratio was - 0.12% [2] 3.5 Profit Analysis - The production profit of butadiene through oxidative dehydrogenation of butene was 186 yuan/ton, and the production profit through C4 extraction was 1,861.1 yuan/ton. The production profit of butadiene rubber was - 225 yuan/ton, and the gross profit rate was - 1.89% [2] 3.6 Geopolitical and Macroeconomic Factors - On September 25 local time, US President Trump announced on his social media platform that a 25% tariff would be imposed on all imported heavy - duty trucks starting from October 1. The crude oil market is in a range - bound game due to geopolitical factors, sanctions, and the expected oversupply in the fundamentals caused by OPEC+ production increases. The US non - farm payroll data for August was lower than market expectations, and the Federal Reserve cut interest rates by 25bp as expected, with two more interest rate cuts expected within the year, with a total cut of 50bp or more. Geopolitical situations in Russia - Ukraine, US - Venezuela, and the Middle East are frequently disturbed in the short - term and show a tense trend [2] 3.7 Trading Strategy - **Single - side Trading**: Oscillating upward - **Arbitrage**: Pay attention to the strategy of going long on BR and short on NR/RU. Key risks to monitor include downstream demand, cost changes, device maintenance, and geopolitical factors [2]
