1. Report Industry Investment Rating - The investment view on butadiene rubber is "oscillation", and the trading strategy suggests a unilateral "oscillatory upward" trend and an arbitrage strategy of "long BR, short NR/RU" [3]. 2. Core View of the Report - The fundamentals of butadiene provide some support, and the profit has improved. The valuation of cis - butadiene rubber has recently been repaired. However, attention should still be paid to the impact of changes in production start - up and inventory clearance progress on the spot trading rhythm [3]. 3. Summary by Relevant Catalogs 3.1 Market Review - This cycle, Sinopec's high - cis butadiene rubber price was cumulatively reduced by 300 yuan/ton, and PetroChina's main sales companies reduced the price by 500 yuan/ton. The cost situation of cis - butadiene rubber has slightly improved. Due to device maintenance, Sinopec's short - and medium - term circulation resources are expected to decrease. Affected by macro news and downstream price - pressing purchases, the spot negotiation price has declined. At the end of the cycle, the price of the cis - butadiene rubber futures and spot markets rebounded rapidly [7]. 3.2 Supply and Demand Analysis 3.2.1 Supply - Last week, China's butadiene production was 102,200 tons (-2.36%), with a capacity utilization rate of 65.79%; high - cis butadiene rubber production was 30,000 tons (0.18%), with a capacity utilization rate of 74.82%. Multiple butadiene and butadiene rubber plants were in a state of maintenance, shutdown, or restart, affecting production volume [3]. 3.2.2 Demand - The capacity utilization rate of China's semi - steel tire sample enterprises was 71.07%, a month - on - month increase of 28.92 percentage points and a year - on - year decrease of 8.57 percentage points; the capacity utilization rate of full - steel tire sample enterprises was 63.96%, a month - on - month increase of 22.43 percentage points and a year - on - year increase of 4.98 percentage points. Most enterprises' capacity utilization rates have returned to pre - holiday levels, but there are differences in shipment performance [3]. 3.3 Inventory Analysis - Last week, the butadiene port inventory was 308,000 tons, a month - on - month increase of 10.99%; the inventory of high - cis butadiene rubber enterprises and traders was 32,760 tons, a month - on - month increase of 1.42%. There is concern about the inventory increase due to the arrival of ocean - going vessels and sufficient expected imports in October [3]. 3.4 Price and Spread Analysis - The BR cross - variety spread and month - to - month spread, as well as the seasonality analysis of RU - BR, NR - BR, and BR - SC, are presented in the report. The RU - BR spread was 3,770 yuan/ton (-7.94%), the NR - BR spread was 1,300 yuan/ton (15.04%), and the BR - SC ratio was 0.52% [3][12]. 3.5 Cost and Profit Analysis - The production gross profit of butadiene by oxidative dehydrogenation was - 124 yuan/ton, and by C4 extraction was 1,816.55 yuan/ton. The production gross profit of cis - butadiene rubber was - 158 yuan/ton, with a gross profit margin of - 1.39% [3]. 3.6 Device Operation Analysis - Multiple butadiene and butadiene rubber plants are in different states of operation, maintenance, or shutdown. For example, many butadiene plants such as Nanjing Chengzhi and Sierbang are in a shutdown state, and some butadiene rubber plants like Qilu Petrochemical and Yangzi Petrochemical are under maintenance [3][11].

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]

Report Industry Investment Rating - The investment view on the synthetic rubber industry is "oscillating bearish" [3] Core Viewpoints of the Report - The domestic butadiene market has weakened, and the list price of cis - butadiene rubber has been lowered. Although downstream demand is recovering, attention should be paid to the support of macro - policies for demand. In terms of valuation, the correlation between BR and NR on the futures market has increased, and the rubber attribute is relatively strong [3] Summary by Relevant Catalogs Market Review - This cycle, Sinopec and PetroChina's major sales companies have cumulatively lowered the price of high - cis cis - butadiene rubber by 200 yuan/ton. As of September 18, 2025, the mainstream ex - factory price of high - cis cis - butadiene rubber in China is between 11,700 - 11,800 yuan/ton [6] - The prices of butadiene, cis - butadiene rubber, and styrene - butadiene rubber have generally declined. For example, the ex - factory price of Dalian Hengli's butadiene has decreased by 100 yuan/ton compared to September 10, with a week - on - week decline of 1.10% [8] Device Status - **Butadiene Devices**: Many devices such as Nanjing Chengzhi, Sierbang, and Yanshan Petrochemical are in a shutdown state. Some devices in Central China have reduced their loads, and some in South China have temporarily shut down, resulting in a continuous decline in production [3] - **Cis - Butadiene Rubber Devices**: Shandong Weite, Taixiang Yubu, and Haopu New Materials' cis - butadiene rubber devices are under maintenance. High - cis cis - butadiene rubber production and capacity utilization are generally stable [3] Market Influencing Factors - **Supply**: The supply of butadiene and cis - butadiene rubber is affected by device shutdowns and maintenance, showing a neutral driving force [3] - **Demand**: In the semi - steel tire market, channel sales have increased, especially in the snow tire market. In the all - steel tire market, the market price is stable, but the replacement market demand has not significantly increased, and some enterprises face export pressure [3] - **Inventory**: Butadiene port inventory and high - cis cis - butadiene rubber enterprise + trader inventory have decreased. However, there is still an expectation of future vessel arrivals for butadiene [3] - **Basis**: The basis of cis - butadiene rubber in North, East, and South China shows a neutral state [3] - **Spread/Price Ratio**: The spreads of RU - BR, NR - BR, and the price ratio of BR - SC are in a bullish state [3] - **Profit**: The production profit of butadiene and cis - butadiene rubber shows a neutral state [3] - **Geopolitical and Macroeconomic Factors**: OPEC+ has started the second - round production increase cycle, the US economic data is weak, the Federal Reserve has cut interest rates, and geopolitical tensions in some regions still exist [3] Trading Strategies - **Single - sided Trading**: Oscillating upward [3] - **Arbitrage Trading**: Pay attention to going long on BR and short on NR/RU [3]

1. Report Industry Investment Rating No information provided regarding the report industry investment rating. 2. Core Viewpoints of the Report - The price of BR rubber shows wide - range volatile movement. The impact of device maintenance on supply is limited, while demand has mixed factors, and inventory has a negative influence. Fundamentals are relatively strong, but trading volume has weakened. In the short - term, the market is expected to remain in a wide - range volatile state [4]. - The trading strategy suggests a unilateral upward trend in volatility. For arbitrage, it is advisable to pay attention to going long on BR and shorting NR/RU. Key factors to watch include downstream demand, cost changes, device maintenance, and geopolitical situations [4]. 3. Summary by Relevant Catalogs 3.1 Market Review - The prices of high - cis butadiene rubber of Sinopec and PetroChina's major sales companies have been reduced by 200 yuan/ton. As of September 11, 2025, the mainstream ex - factory price of high - cis butadiene rubber in China is between 11,900 - 12,000 yuan/ton [7]. - The suspension of several butadiene rubber devices has led to a slight decline in domestic production and capacity utilization. However, the sufficient supply of most brands limits the price increase. Weakening demand for raw material butadiene and price softening, along with downstream purchasing behavior, have put pressure on prices [7]. 3.2 Refinery Device Maintenance Plan - In 2025, many refineries of Sinopec, PetroChina, and CNOOC have device maintenance plans, involving various regions and different types of devices, with a wide range of maintenance capacities and time spans [12]. 3.3 Butadiene and Butadiene Rubber Device Maintenance Data Statistics - Many butadiene production enterprises have experienced device shutdowns, affecting production capacity. For butadiene rubber, some devices are in normal operation, while others are under maintenance, and some have future shutdown plans [13]. 3.4 Butadiene and Butadiene Rubber Market Data - **Supply**: Butadiene production and high - cis butadiene rubber production and capacity utilization have declined due to device shutdowns [4]. - **Demand**: In the semi - steel tire market, the replacement market is stable, with increased production of winter tires and some shortages in all - season tires. In the all - steel tire market, the replacement market price is stable, with a slight improvement in trading volume [4]. - **Inventory**: Butadiene port inventory has decreased, while butadiene rubber enterprise and trader inventories have increased [4]. - **Basis**: The basis of butadiene rubber in North China is - 165 yuan/ton, in East China is - 65 yuan/ton, and in South China is 35 yuan/ton [4]. - **Spread/Price Ratio**: The RU - BR spread is 4,205 yuan/ton (2.19%), the NR - BR spread is 940 yuan/ton (6.82%), and the BR - SC price ratio is - 0.36% [4]. - **Profit**: The production profit of butadiene through oxidative dehydrogenation is 36 yuan/ton, and through C4 extraction is 1,997.21 yuan/ton. The production profit of butadiene rubber is - 128 yuan/ton, with a gross profit margin of - 1.06% [4].

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]

Report Industry Investment Rating - The investment view on butadiene rubber is a bearish oscillation, indicating that the price of butadiene rubber is expected to fluctuate at a low level in the short term [4]. Core View of the Report - The sentiment has declined, and there are negative factors on the cost side. The price of butadiene rubber (BR) is oscillating at a low level. The supply of butadiene rubber is expected to increase in August, while the demand shows a neutral trend. The inventory and basis show a positive trend, and the profit and geopolitical - macro factors are negative [4]. Summary According to Relevant Catalogs Market Review - This week, the price of high - cis butadiene rubber of Sinopec Chemical Sales has been reduced by 400 yuan/ton in total, and that of major sales companies of PetroChina has been reduced by 100 yuan/ton in total. As of July 24, 2025, the mainstream ex - factory price of high - cis butadiene rubber in China is between 11,800 and 12,100 yuan/ton. The market sentiment has changed, and the prices of butadiene rubber, raw material butadiene, and related natural rubber have gradually declined [7]. Supply and Demand Analysis Supply - Last week, the domestic butadiene production was 1.034 million tons, with a capacity utilization rate of 69.97%. The production of high - cis butadiene rubber was 910,000 tons, with a capacity utilization rate of 72.46%. Some butadiene devices were shut down or under maintenance, and the production of butadiene rubber is expected to continue to increase in August [4]. Demand - For semi - steel tires, the replacement market's sales performance has continued the weak trend of last week, and the terminal demand has not improved significantly. For all - steel tires, the market transactions have increased slightly compared with last week, and some brands may raise prices next month [4].
