Report Industry Investment Rating - No relevant content provided Core Views of the Report - This week, the natural rubber market showed a trend of rising first and then falling under the combined influence of fundamentals and macro - sentiment. In the first half, strong raw material prices, continuous inventory reduction, and positive macro - expectations supported the rise of rubber prices; in the second half, after the macro - positive factors materialized, the market sentiment turned cautious, and rubber prices declined. In the future, heavy rainfall in major producing areas will limit rubber tapping, and raw material prices are expected to remain firm. On the demand side, tire companies still face shipment pressure, and foreign trade orders are under - performing. Some companies plan to reduce production or conduct maintenance in November, which will restrict the improvement of overall production capacity utilization. Overall, raw material prices will provide short - term support, but there is a lack of substantial positive factors on the demand side. Therefore, rubber prices are expected to fluctuate next week [3] Summary According to Relevant Catalogs Natural Rubber Price Data - As of October 30, the mainstream price of domestic full - latex in the Shanghai market was 14,800 yuan/ton, up 200 yuan/ton from last week. The US dollar price of Thai - produced 20 - standard rubber in the Qingdao Free Trade Zone was 1,870 US dollars/ton, up 10 US dollars/ton from last week [3] Main - producing Countries' Rubber Output and China's Natural Rubber Imports - No specific data analysis in the text, only historical data charts of ANRPC member countries' natural rubber output and China's natural rubber imports are presented [10][11][12] Tire Output - No specific data analysis in the text, only historical data charts of tire output are presented [13][14] Tire Enterprise Operating Rates - This week, the capacity utilization rate of semi - steel tire sample enterprises was 72.12%, a month - on - month decrease of 0.72% and a year - on - year decrease of 7.61%.

1. Report Industry Investment Rating - The investment rating for the natural rubber industry is "oscillating" [3] 2. Core Viewpoints of the Report - The natural rubber market showed a trend of rising first and then falling this week. With the reduction of precipitation in domestic production areas, the supply increased significantly. Overseas production areas were affected by rain, leading to high raw material prices. The production scheduling of downstream enterprises was better than expected, and the capacity utilization rate increased significantly. The inventory in the middle - stream continued to decline. However, the overall sentiment in the commodity market weakened, causing rubber prices to fall from high levels. In the short term, due to factors such as the weakening of precipitation in production areas, strong cost support, a slight decline in middle - stream inventory, an increase in downstream operating rates, and weakening commodity market sentiment, the market is expected to maintain an oscillating performance [3][6] 3. Summary According to Relevant Catalogs 3.1 Main Viewpoints and Strategy Overview - **Supply**: It is bearish. In domestic production areas, the weather in Yunnan improved, and the supply - side pressure eased, but the strong demand for raw materials from processing plants supported a slight increase in raw material prices. In Hainan, the weather was good, and raw material output increased seasonally. In Thailand, continuous rain affected rubber tapping, leading to a shortage of raw material supply and rising prices. In Vietnam, the weather improvement was limited, and the shortage of raw materials continued [3] - **Demand**: It is neutral. This week, the capacity utilization rates of China's all - steel and semi - steel tire sample enterprises increased. It is expected that most enterprises will maintain their current production schedules in the next period, with only small fluctuations in overall capacity utilization [3] - **Inventory**: It is neutral. As of September 7, 2025, China's natural rubber social inventory decreased. The warehouse receipt inventories of RU and 20 - numbered rubber on the futures exchanges also decreased [3] - **Basis/Spread**: It is neutral. The RU - mixed spread narrowed slightly, and the spread between the RU and NR main contracts widened [3] - **Profit**: It is bullish. The theoretical production profit of Thai standard rubber was in a loss state, the theoretical production loss of domestic concentrated latex in Hainan narrowed, and the delivery profit of Yunnan whole milk was still in a loss range [3] - **Valuation**: It is bearish. The current absolute price is at a moderately high level, and the overall valuation is still moderately high [3] - **Commodity Market**: It is neutral. The expectation of the Fed's interest rate cut increased, the yield of US Treasury bonds decreased, and the risk appetite in the financial market increased. However, the domestic commodity market temporarily lacked driving forces, and the market sentiment was weak [3] - **Investment Viewpoint**: It is oscillating. Considering various factors, the market is expected to maintain an oscillating performance in the short term [3] - **Trading Strategy**: For unilateral trading, buy RU on dips; for arbitrage, go long on BR and short on NR [3] 3.2 Futures and Spot Market Review - **Market Sentiment and Price Trend**: The market sentiment cooled down, and rubber returned to a weak state. This week, natural rubber rose first and then fell. As of September 12, the RU main contract closed at 15,820 yuan/ton, down 3.09% week - on - week, and the 20 - numbered rubber main contract closed at 12,555 yuan/ton, down 4.09% week - on - week [6] - **Spot Market**: Spot prices fell slightly [9] - **Position on the Futures Board**: The position of the RU2601 contract decreased significantly, and the total position of NR decreased slightly [16][23] - **Spread on the Futures Board**: The RU - NR spread widened slightly [30] 3.3 Rubber Supply and Demand Fundamental Data - **Production Area Weather**: The rainfall in production areas decreased [37] - **Production and Export of Main Producing Countries**: In July, the cumulative export volume of ANRPC was 5.443 million tons, a year - on - year increase of 5.54%. From January to July, China imported 3.6005 million tons of natural rubber, a year - on - year increase of 21.82%. In August 2025, China imported 664,000 tons of natural and synthetic rubber (including latex), a year - on - year increase of 7.8%. From January to August, the total import volume was 5.373 million tons, a year - on - year increase of 19% [72][85][92] - **Middle - Stream Inventory**: China's natural rubber social inventory decreased slightly. As of September 7, 2025, the social inventory was 1.258 million tons, a week - on - week decrease of 0.7 million tons, or 0.57% [100][107] - **Downstream Tire Demand**: The capacity utilization rate of tires increased. This week, the capacity utilization rates of all - steel and semi - steel tire sample enterprises increased. It is expected that the overall capacity utilization rate will fluctuate slightly in the next period [108][117] - **Automobile and Heavy - Truck Market**: In July, the growth rate of automobile sales expanded. In August, the sales volume of heavy - trucks increased significantly year - on - year [123] - **Tire Export**: From January to July, the export volume of tires was 5.34 million tons, a year - on - year increase of 4.9% [132] - **Cost and Profit**: The production profit of Thai standard rubber was in a loss state, and the profit of Thai latex decreased [141]

Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core View The global natural rubber producing areas are in the tapping season. Supply in Yunnan is increasing, while in Hainan, rainfall has disrupted tapping and slowed the seasonal increase in raw materials. Some factories are competing to buy raw materials, and the purchase price of latex has been raised. Recently, the inventory at Qingdao Port has continued to decline, and the destocking rate has increased month - on - month. However, the destocking rate of general trade inventory may narrow. In terms of demand, the overall capacity utilization rate will increase this week as some enterprises resume production after maintenance, but the increase in production may be limited due to some enterprises' production control plans. The ru2601 contract is expected to fluctuate between 15,800 - 16,500 yuan/ton in the short - term, and the nr2511 contract is expected to fluctuate between 12,550 - 13,200 yuan/ton in the short - term [2]. 3.

Report Summary 1) Report Industry Investment Rating No information provided. 2) Core Viewpoints - The global natural rubber producing areas are in the tapping season. The supply in Yunnan is gradually increasing, and the raw material purchase price is firm. The raw material output in Hainan is seasonally increasing, but the factories are not willing to replenish high - priced raw materials, and the purchase price of latex is lowered. Recently, the inventory at Qingdao Port has continued to decline, and the de - stocking rate has increased month - on - month. However, as tire factories become more risk - averse, the de - stocking rate of general trade inventory may narrow month - on - month. In terms of demand, the overall capacity utilization rate will increase this week as the production of maintenance enterprises resumes, but the increase in the start - up rate may be limited due to the general shipment of some enterprises and production control plans within the month.
