Group 1 - The domestic futures market for rubber is experiencing a downward trend, with the main contract for 20 rubber futures opening at 12,550.00 CNY/ton and showing a decline of approximately 3.10% [1] - The market sentiment is influenced by seasonal factors, with expectations for improved terminal consumption during the "Golden September and Silver October" period, despite the current weak performance of rubber prices [1] - Supply constraints are noted due to adverse weather conditions affecting rubber tapping operations in both domestic and overseas production areas, leading to a tightening of raw material availability [2] Group 2 - The macro market sentiment is recovering, and supply disruptions are continuing, leading to a stabilization and potential upward movement in rubber prices [2] - Inventory levels for natural rubber are decreasing, particularly in the Qingdao region, indicating a tightening supply situation [2] - The return of the La Niña phenomenon may impact global weather patterns, although many regions are still expected to experience above-average temperatures [2]

Report Industry Investment Rating - RU and NR are rated neutral; BR is rated neutral [6] Core View of the Report - For RU and NR, in the next one to two weeks, domestic rainfall is expected to decrease, but overseas main production areas like Thailand are still affected by rainfall, keeping overseas raw material prices firm and providing strong cost - side support. Domestic arrivals are slightly recovering, but downstream concentrated purchasing has led to a significant reduction in Qingdao port inventory. After maintenance, downstream tire开工率 has rebounded, and overall downstream demand is improving seasonally. In the short term, there may still be a slight reduction in inventory, and rubber prices are expected to remain firm. However, there will be pressure for port inventory to rise after downstream stocking ends. - For BR, there are concerns about cost - side drag recently. The weakening of crude oil prices may lead to an adjustment in butadiene prices, and butadiene inventory is gradually rising, which may cause pressure after downstream restocking ends. However, the fundamentals of BR itself are still good, with several production facilities having maintenance plans, expected to lead to a phased decline in supply. Downstream tire demand is in a peak season, and the large price difference with natural rubber supports BR prices [6] Summary by Related Catalogs Market News and Data - Futures: The closing price of the RU main contract was 15,880 yuan/ton, down 160 yuan/ton from the previous day; the NR main contract was 12,590 yuan/ton, down 125 yuan/ton; the BR main contract was 11,590 yuan/ton, down 85 yuan/ton. - Spot: The price of Yunnan - produced whole latex in the Shanghai market was 15,100 yuan/ton, down 100 yuan/ton; Qingdao Free Trade Zone Thai mixed rubber was 15,000 yuan/ton, down 150 yuan/ton; Thai 20 - grade standard rubber in Qingdao Free Trade Zone was 1,860 US dollars/ton, down 10 US dollars/ton; Indonesian 20 - grade standard rubber in Qingdao Free Trade Zone was 1,780 US dollars/ton, down 10 US dollars/ton; the ex - factory price of BR9000 of PetroChina Qilu Petrochemical was 11,900 yuan/ton, unchanged; the market price of BR9000 in Zhejiang Transfar was 11,550 yuan/ton, unchanged [1] Market Information - Import: In August 2025, China imported 664,000 tons of natural and synthetic rubber (including latex), a 7.8% increase from the same period in 2024.

As the seasonal peak season may be approaching, the raw material inventory for agricultural films has started to build up, and the overall operating rate has stabilized at a low level [18] Polypropylene - **Market Quotes**: Futures prices rose. There is still 145 tons of planned production capacity, resulting in high supply pressure. The downstream operating rate has rebounded from a seasonal low [19] - **Fundamentals**: In a context of weak supply and demand, the overall inventory pressure is high, and there is no obvious short - term contradiction.

Core Viewpoint - The domestic natural rubber market is experiencing a strong upward trend due to a temporary tightening of supply, steady demand growth, and favorable macroeconomic factors [1] Demand Side Expectations - Internationally, expectations for a Federal Reserve interest rate cut have increased, providing support for the commodity market. August non-farm payrolls added 22,000 jobs, significantly below the market expectation of 75,000, which has enhanced market expectations for the probability and extent of rate cuts. The upcoming Federal Reserve meeting on September 16-17 will be crucial [2] - Domestically, multiple policies are working together to boost consumer confidence and improve market development expectations. The reintroduction of national subsidies in September, focusing on the automotive sector, is expected to increase vehicle sales by 10%, directly benefiting downstream demand for natural rubber. In August, domestic automobile production reached 2.815 million units, a month-on-month increase of 223,900 units, with a growth rate of 8.64%. The inventory warning index for automobile dealers decreased by 0.2 percentage points month-on-month, indicating a clear trend of increased production and reduced inventory [2] - With the arrival of the "Golden September and Silver October" consumption peak season, coupled with the national subsidy policy, tire manufacturers' operating rates are expected to further rise. As of September 12, the operating rate of domestic all-steel tires rose to 66.31%, a weekly increase of 5.57 percentage points, while the operating rate of semi-steel tires reached 72.61%, a weekly increase of 5.69 percentage points. Although the inventory days in Shandong remain at a high level compared to the past five years, they have decreased by 1.69% from the previous month, indicating a marginal alleviation of inventory pressure [2] Supply Side Conditions - As rainfall decreases and weather improves in major production areas, the efficiency of rubber tapping has increased, leading to a weakening of support for rubber prices from the raw material side. Although Thailand and Hainan are still experiencing peak rainfall, the weekly rainfall in Thailand has decreased by 1.08%, while Hainan's rainfall has increased by 133.02%. The peak rainfall season in Yunnan has ended, with a recent weekly decrease of 21.21% in rainfall, significantly improving tapping conditions [3] - Raw material prices are stabilizing domestically while showing slight declines internationally. As of September 15, the price of Yunnan rubber remained at 14,800 yuan per ton, stable in recent times. The FOB price of Thai cup rubber has dropped to 51 Thai baht per kilogram, down 1.7 Thai baht per kilogram from the previous week, while the FOB price of cup rubber has slightly increased by 0.2 Thai baht per kilogram compared to last week [3] Potential Risks - On September 10, Mexico proposed to raise tariffs on cars from Asia to a maximum of 50% to protect local jobs. If this policy is implemented, it may impact domestic automobile exports and subsequently affect natural rubber demand. However, there has not yet been a substantial impact [4] - Previously, OPEC+ maintained its production increase strategy, leading to expectations of falling oil prices, which in turn dragged down synthetic rubber prices and affected natural rubber trends. Future international geopolitical conflicts may boost oil prices, causing fluctuations in synthetic rubber prices. As a major substitute for natural rubber, the price trends of synthetic rubber will continue to influence market sentiment for natural rubber [4] - Overall, the current domestic natural rubber market's growth in demand, tightening inventory, and favorable macroeconomic fundamentals remain unchanged. Although the marginal supply from production areas has weakened raw material support, the resilience of demand and macroeconomic support still dominate the market [4]
