合成橡胶投资周报：宏观情绪推波助澜，BR维持宽幅震荡-20260202

1. Report Industry Investment Rating - The investment rating for butadiene rubber is "oscillating with a bullish bias" [4] 2. Core Viewpoints of the Report - Butadiene has strong fundamental support, while cis - butadiene rubber faces profit and inventory pressures, and the number of warehouse receipts is increasing. With high bullish sentiment from macro and capital factors, both futures and spot prices are rising. Before the Spring Festival, there is an expectation of reduced production at cis - butadiene plants, and trading volume among traders and downstream users is decreasing. In the short - term, the futures price is expected to oscillate widely in the range of 12,800 - 13,300 yuan/ton, and in the long - term, the price of synthetic rubber is expected to rise further [4] 3. Summary According to Relevant Catalogs 3.1 Market Review - This week, the price of cis - butadiene rubber in the Shandong market rose significantly and then oscillated at a high level, with the spot price ranging from 12,300 to 13,100 yuan/ton. The increase was mainly due to the tight supply and rising prices of overseas butadiene resources, as well as the positive commodity market atmosphere. However, downstream users showed resistance to high prices, and the production of some northern private cis - butadiene rubber plants was reduced due to losses. Overall, the domestic production volume changed little [6] 3.2 Influence Factors of Butadiene Rubber 3.2.1 Supply - Last week, the domestic butadiene production was [unspecified] tons, with a capacity utilization rate of [unspecified]%; the production of high - cis butadiene rubber was [unspecified] tons, with a capacity utilization rate of [unspecified]%. Some butadiene plants remained shut down, while some restarted, and the weekly production increased. For cis - butadiene rubber, the plant of Maoming Petrochemical restarted, but attention should be paid to the operating load of private plants in North China due to poor profitability [4] 3.2.2 Demand - For semi - steel tires, agents made small - scale purchases at the end of the month, but the sales in the distribution channels and at the terminal were weak, inventory consumption was slow, and social inventory increased. For all - steel tires, the market remained sluggish in the second half of the month, with weak sales in distribution channels and at the terminal. Merchants focused on collecting payments, and the promotional policies of some brands were ineffective. Downstream users were cautious about purchasing and mostly postponed their procurement until after the festival [4] 3.2.3 Inventory - Last week, the port inventory of butadiene was 40,500 tons, a 17.39% increase from the previous week; the inventory of high - cis butadiene rubber among enterprises and traders was 34,430 tons, a 2.74% decrease from the previous week. The port inventory of butadiene increased due to the arrival of imported ships, while the inventory of cis - butadiene rubber at production enterprises decreased due to production losses and reduced operating loads, and the inventory of trading enterprises increased slightly [4] 3.2.4 Basis - The basis of cis - butadiene rubber in North China was - 890 yuan/ton, in East China was - 790 yuan/ton, and in South China was - 790 yuan/ton [4] 3.2.5 Spread/Price Ratio - The spread between RU and BR was 2,970 yuan/ton; the spread between NR and BR was - 155 yuan/ton; the price ratio of BR to SC was - 0.41% [4] 3.2.6 Profit - The production profit of butadiene through oxidative dehydrogenation was 1,918 yuan/ton, and through C4 extraction was 3,512.64 yuan/ton. The production profit of cis - butadiene rubber was - 418 yuan/ton, with a gross profit margin of - 3.12% [4] 3.2.7 Geopolitical and Macroeconomic Factors - Last week, the EIA crude oil inventory in the US increased by 3.6 million barrels more than expected, and the IEA maintained its expectation of a loose crude oil supply in 2026. Sinopec and China National Aviation Fuel Group were restructured. Tensions in the Middle East and the Russia - Ukraine region escalated due to the US's attack on Iran. The natural gas price soared by 60% due to the cold wave, and oil and gas prices rose in the short - term. Incidents such as the Trump administration's attempt to occupy Greenland and seize Russian oil tankers also increased market panic about geopolitics [4] 3.3 Trading Strategies - For single - sided trading, the strategy is mainly to buy on dips and follow the market and capital trends. For arbitrage, the strategy is to go long on BR and short on NR/RU [4] 3.4 Correlation Analysis of Related Varieties of Synthetic Rubber - The report provides correlation coefficient heat maps of price trends for crude oil, synthetic rubber, and natural rubber - related varieties over 1 - month and 3 - month periods, showing the relationships between different varieties [11] 3.5 Device Status - The report lists the maintenance and shutdown status of butadiene plants and high - cis butadiene rubber plants in China in 2026, including production enterprises, maintenance capacity, shutdown time, and expected startup time [12][13]
