1. Report Industry Investment Rating No information provided in the document. 2. Core Viewpoints of the Report - The rise in butadiene rubber prices may be due to factors such as macro - capital allocation to chemical commodities, the implementation of naphtha consumption tax, geopolitical risks affecting international crude oil prices, overseas device maintenance, and supply - demand imbalances in butadiene [10]. - The market logic for rubber is that the bulls are mainly driven by China's winter storage expectations and positive policy expectations, while the bears are mainly concerned about weak demand and the expected negative impact of tariff policies [12]. - The price of butadiene rubber is mainly affected by the price of raw material butadiene, and its own supply - demand driving factors are not significant. During the 14th Five - Year Plan period, China's ethylene industry will enter a new cycle of capacity expansion, and butadiene capacity will increase passively as a supporting project for refining projects [119][122]. 3. Summary According to Relevant Catalogs 3.1. Weekly Assessment and Strategy Recommendation - Reasons for the rise in butadiene rubber: macro - capital allocation to chemical commodities, naphtha consumption tax, geopolitical risks and cold snaps affecting crude oil prices, overseas device maintenance, and supply - demand imbalances in butadiene [10]. - Rubber RU summary: macro - capital allocation to chemicals drives the rise of butadiene and rubber [11]. - Market logic: bulls focus on China's winter storage and policy expectations, while bears are concerned about weak demand and tariff policies. Short - term rubber prices are strongly affected by macro - capital and are currently neutral. It is recommended to consider a hedging strategy of going long on NR main contract and shorting RU2609 [12]. - Trading strategy: a hedging strategy of going long on NR main contract and shorting RU2609 with a profit - loss ratio of 1.5:1, recommended for an indefinite period. Build positions gradually when the price difference is above 3150 and conduct repeated band operations [14]. 3.2. Spot and Futures Market - Rubber maintains its seasonal pattern, with prices more likely to fall in the first half of the year. The ratio of rubber to other commodities such as crude oil, copper, and stocks shows certain trends, and overseas demand for rubber is expected to weaken marginally while Chinese demand remains stable [21][26][29]. 3.3. Profit and Price Ratio - The ratios of rubber to copper, Brent crude oil, rebar, iron ore, Shanghai Composite Index, and ChiNext Index are generally normal, showing no special values or points of concern [36][39][43]. 3.4. Cost Side - The cost of Thai cup rubber is generally considered to be 30 - 35 Thai baht. The cost of Hainan full - latex in China is around 13,500 yuan, and that of Yunnan full - latex is around 12,500 - 13,000 yuan. Rubber maintenance costs are dynamic and related to rubber prices [47]. 3.5. Demand Side - The operating rates of full - steel and semi - steel tire factories are 62.62% (-0.31%) and show certain trends. The prosperity of trucks and commercial vehicles is slowly improving, and the export of truck tires is booming but expected to decline slightly in the future [50][55][58]. 3.6. Supply Side - Rubber import data has limited availability for analysis. The supply of rubber in major producing countries is generally normal, with no special values or points of concern. In November 2025, rubber production, exports, and consumption showed certain year - on - year and month - on - month changes [62][66][97]. - There are many new butadiene and ethylene production capacity projects. The supply of butadiene is expected to increase, and its processing profit is expected to decline. The price of butadiene rubber is mainly affected by the price of butadiene, and the balance of supply and demand depends on the progress of downstream supporting projects [116][117][122].
