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.

Report Summary 1. Industry Investment Rating No specific industry investment rating is provided in the report. 2. Core Viewpoints - **Short - term**: RU is neutral - biased long, NR is neutral. As of August 29, RU and NR prices rose, the RU - NR spread widened, and the RU09 - 01 spread widened. RU's recent frequent rainfall in production areas hindered tapping, leading to tight raw material supply and strong glue prices, with a slight reduction in light - colored rubber inventory. NR was affected by typhoons in Vietnam, with slow supply increase in overseas main production areas, stronger Thai cup - lump prices, and a slight reduction in dark - colored rubber inventory. However, tire开工率 declined, semi - steel tire inventory digestion was slow, and tire exports over - drafted subsequent demand, and domestic demand awaited verification during the "Golden September and Silver October" peak season. It is judged that RU prices will fluctuate widely this week, and NR prices will fluctuate with a slight upward trend [4]. - **Medium - to long - term**: RU is neutral - biased short, NR is neutral - biased short. The factors affecting long - term trends are similar to short - term ones, mainly considering the supply - demand relationship in the tire market and the impact of weather on rubber production [4]. 3. Summary by Related Catalogs **Market Data** - **Prices**: As of August 29, Thai cup - lump price was 50.5 Thai baht/kg, up 1 Thai baht/kg from last week; Thai glue price was 55.45 Thai baht/kg, up 0.45 Thai baht/kg from last week. Shanghai state - owned whole milk price was 14,900 yuan/ton, up 250 yuan/ton from last week; Shanghai Vietnam 3L price was 15,100 yuan/ton, up 300 yuan/ton from last week; Shanghai RSS3 price was 19,900 yuan/ton, up 200 yuan/ton from last week.

The RU09 - 01 spread was - 975 yuan/ton, down 20 yuan/ton from last week; the RU01 - 05 spread was - 80 yuan/ton, up 20 yuan/ton from last week; the NR consecutive one - consecutive two spread was - 30 yuan/ton, down 5 yuan/ton from last week; the NR consecutive two - consecutive three spread was - 30 yuan/ton, up 20 yuan/ton from last week [4][94][109]. **Supply - related** - **Production Areas Weather**: During the period from August 26 to September 2, Vietnam was affected by typhoons "Jianyu" and "Lanhu". The estimated rubber production loss due to heavy rainfall was about 0.29 - 0.48 tons, which will be released after the weather improves. Yunnan's rainfall gradually subsided, while Hainan was more significantly affected by typhoon "Lanhu", with expected increased rainfall that would hinder tapping [10][31]. - **Thai Supply**: Thai weather was normal, raw material prices increased marginally, and production was stable. The Thai Rubber Authority (RAOT) launched a plan to export rubber to China via the Mekong River with zero import tax, aiming to increase prices. The first batch of 400 tons of cup - shaped rubber will be shipped in September this year, and commercial shipments are planned to start in October 2025, with production increasing to 2,400 tons [4][21]. - **Ivory Coast Exports**: In July 2025, Ivory Coast exported 2.85 tons of natural rubber to China, a decrease of 0.55 tons from the previous month, a month - on - month decrease of 16.29% and a year - on - year increase of 92.59%. From January to July 2025, Ivory Coast's total exports of natural rubber to China were 27.84 tons, a decrease of 9.61 tons compared to the same period, with a total year - on - year increase of 52.73% [26]. **Demand - related** - **Tire Industry**: As of August 29, the semi - steel tire开工率 was 72.77%, down 0.36% from last week.

Due to anti - dumping measures in the EU, there was a rush to export, over - drafting subsequent orders, and downstream tire factories were pessimistic, making short - term inventory digestion difficult. As of August 28, the whole - steel tire开工率 was 63.84%, down 0.92% from last week. In July 2025, the export volume of Chinese whole - steel tires was 45.44 tons, a decrease of 4.72 tons from the previous month, a month - on - month increase of 11.6% and a year - on - year increase of 13%. Enterprises' exports remained active, domestic sales were stable, and it is expected that the开工率 will improve in September [55][61]. - **Inventory**: As of August 24, the total social inventory of light - colored rubber was 47.3 tons, a month - on - month decrease of 1.25%; the total social inventory of dark - colored rubber was 79.7 tons, a month - on - month decrease of 1.12%. As of August 29, the combined inventory of bonded and general trade of natural rubber in Qingdao was 60.23 tons, a decrease of 0.4 tons from the previous period, a decrease of 0.6%. The bonded area inventory was 7.32 tons, a decrease of 0.14%; the general trade inventory was 52.91 tons, a decrease of 0.7%. It is expected that the inventory in Qingdao Port will continue to decline slightly in the next period [4][48][94].

1. Report Industry Investment Rating - No relevant information provided 2. Core View of the Report - The inventory at Qingdao Port continued to decline, with a slightly reduced decline rate. The inbound volume increased month - on - month, but the outbound volume increase was average. Downstream tire enterprises' procurement was relatively moderate, and it is expected that the inventory at Qingdao Port will continue to decline slightly in the short term. In terms of demand, most semi - steel tire enterprises' equipment operated stably last week, while some enterprises had maintenance due to high shipment pressure, dragging down the overall capacity utilization rate. All - steel tire enterprises' equipment also operated stably, mostly continuing the previous production control state. Some enterprises had maintenance plans at the beginning of this month, which may still have a certain impact on short - term capacity utilization. The ru2601 contract is expected to fluctuate in the range of 15,650 - 16,200 in the short term, and the nr2510 contract is expected to fluctuate in the range of 12,520 - 13,000 in the short term [2] 3.

Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints - Global natural rubber production areas are gradually opening for tapping. In Yunnan, heavy rainfall restricts glue output, and with strong competition from latex factories, raw material prices remain firm. In Hainan, rainfall disrupts local areas, limiting the increase in raw material supply. Local factories generally increase prices for raw material procurement. - Recently, the total spot inventory at Qingdao Port has continued to accumulate, with both bonded and general trade warehouses showing inventory growth. Overseas shipments arriving at the port for storage have increased, but downstream tire companies are mainly replenishing stocks in moderation and observing, which suppresses the port's shipping rate, resulting in continued inventory accumulation at Qingdao Port. - In terms of demand, last week, the capacity utilization rates of domestic tire companies varied. The production schedules of semi - steel tire companies that had maintenance at the beginning of the month gradually resumed, which boosted the overall capacity utilization rate of tire companies. The maintenance of individual all - steel tire companies slightly dragged down the all - steel tire capacity utilization rate. This week, the production schedules of maintenance companies will return to normal levels, and there is still room for the capacity utilization rate to recover, which will drive the overall capacity utilization rate of tire companies. - The ru2509 contract is expected to fluctuate in the range of 14,000 - 14,500 yuan/ton in the short term, and the nr2509 contract is expected to fluctuate in the range of 12,150 - 12,500 yuan/ton in the short term.
