Report Industry Investment Rating - The investment rating for RU and NR is neutral, and the same for BR [7] Core Viewpoints - The price of raw materials remains strong, providing cost support for rubber. In the short term, the domestic supply pressure is not obvious, and the overall demand has rigid support. The valuations of RU and NR are low, with potential for a low - level rebound. The supply of BR may decrease in the future, and its price is likely to rise but the high inventory may limit the rebound space [1][7] Summary by Related Catalogs Market News and Data - **Futures Prices**: On the previous trading day's close, the RU main contract was at 15,150 yuan/ton, up 340 yuan/ton; the NR main contract was at 12,365 yuan/ton, up 185 yuan/ton; the BR main contract was at 11,040 yuan/ton, up 200 yuan/ton [1] - **Spot Prices**: The Shanghai market price of Yunnan - produced whole latex was 14,400 yuan/ton, up 200 yuan/ton.

The basis continues to strengthen. Currently, rainfall in domestic producing areas has decreased significantly, and raw material prices are falling. However, there is still a lot of rain in northern Thailand, and the price of cup lump remains strong, supporting the rubber price. The operating rate of downstream tire factories has rebounded, and exports show certain resilience, with overall demand having rigid support. Before the domestic arrivals increase, the domestic supply pressure is not obvious. Currently, the valuations of RU and NR in China are low, and there may be a demand for a low - level rebound [7] - **BR**: In late October, the maintenance of domestic upstream butadiene rubber plants will increase, and the supply may decrease, which may support the price of butadiene rubber. The operating rate of downstream tire factories has rebounded, and exports show certain resilience, with overall demand having rigid support. Supply and demand may improve to some extent. The price of upstream butadiene raw materials is expected to be stable, and the surrounding natural rubber price also provides bottom support for the butadiene rubber price. It is expected that the price of butadiene rubber will be more likely to rise than fall this week. However, the current high inventory of butadiene rubber may limit the rebound space [7]

Report Industry Investment Rating - The investment ratings for RU and NR are neutral, and the rating for BR is also neutral [6] Core Viewpoints - For natural rubber, the overall domestic supply - demand is gradually turning to a loose pattern, with expected slower inventory reduction or restocking, but the low valuation limits the downside. For BR, the supply - demand is expected to be strong in the later period, and the high inventory may lead to a slight decline following the upstream butadiene price [6] Market News and Data Futures - On the previous trading day's close, the RU main contract was at 14,895 yuan/ton, up 50 yuan/ton from the previous day; the NR main contract was at 12,235 yuan/ton, up 245 yuan/ton; the BR main contract was at 10,895 yuan/ton, up 115 yuan/ton [1] Spot - The Shanghai market price of Yunnan - produced whole latex was 14,300 yuan/ton, up 50 yuan/ton.

The STR20 was quoted at 1,850 US dollars/ton (up 30), the spread between the whole latex and 3L was - 700 yuan/ton (unchanged); the spread between the mixed rubber and styrene - butadiene rubber was 3,300 yuan/ton (up 350) [3] Raw Materials - Thai smoked sheet was 57.19 Thai baht/kg (down 0.46), Thai latex was 54.10 Thai baht/kg (unchanged), Thai cup lump was 49.65 Thai baht/kg (down 0.30), and the spread between Thai latex and cup lump was 4.45 Thai baht/kg (up 0.30) [4] 开工率 - The operating rate of all - steel tires was 41.53% (down 13.83%), and the operating rate of semi - steel tires was 42.15% (down 17.50%) [5] Inventory - The social inventory of natural rubber was 1,112,557 tons (down 122,953), the natural rubber inventory at Qingdao Port was 461,188 tons (down 125,451), the RU futures inventory was 144,390 tons (down 5,420), and the NR futures inventory was 41,329 tons (down 705) [5] 顺丁橡胶 Spot and Spreads - On October 15, 2025, the BR basis was - 145 yuan/ton (down 115), the ex - factory price of butadiene from Sinopec was 8,600 yuan/ton (unchanged), the price of BR9000 from Qilu Petrochemical was 11,200 yuan/ton (unchanged), the price of BR9000 in Zhejiang Transfar was 10,800 yuan/ton (unchanged), the price of private - owned cis - butadiene rubber in Shandong was 10,620 yuan/ton (down 30), and the import profit of cis - butadiene rubber in Northeast Asia was - 2,258 yuan/ton (down 63) [5] 开工率 - The operating rate of high - cis cis - butadiene rubber was 74.69% (up 4.15%) [5] Inventory - The inventory of cis - butadiene rubber traders was 4,860 tons (down 840), and the inventory of cis - butadiene rubber enterprises was 27,900 tons (up 1,300) [5] Strategy - For RU and NR, maintain a neutral view. Currently, NR is relatively undervalued overseas, and its price performance is significantly stronger than RU, causing the spread between RU and NR to narrow recently. After the rainfall in the main production areas at home and abroad decreases, production gradually recovers, and domestic raw material prices decline. Thai raw material prices remain firm, mainly due to more rain in northern Thailand, but with less rain in southern Thailand, the latex price has loosened. The cost - side support for rubber has no obvious change. In the peak season with reduced rain, the supply is expected to recover. After the downstream tire factories stocked up intensively before the festival, the raw material demand will slow down this week, but the operating rate of tire factories is rising, and the rigid demand remains. The domestic arrival volume is likely to continue to rise, and the overall domestic supply - demand is gradually turning to a loose pattern, with expected slower inventory reduction or restocking. However, the current valuations of domestic RU and NR are low, and the downside is expected to be limited. - For BR, maintain a neutral view. In October, there are still maintenance plans for domestic cis - butadiene rubber plants, and the scale of maintenance may be the same as in September, providing support on the supply side. After the downstream tire factories stocked up intensively before the festival, the raw material demand will slow down this week, but the operating rate of tire factories is rising, and the rigid demand remains. The overall operating rate of cis - butadiene rubber this year is still at a high level compared to the same period, and the pattern of abundant supply remains unchanged. It is expected that the downstream will continue to show peak - season characteristics, and the supply - demand of cis - butadiene rubber will be strong. The current high inventory may lead to a slight decline following the upstream butadiene price [6]

1. Report Industry Investment Rating - RU and NR are rated neutral [7] - BR is rated neutral [7] 2. Core View of the Report - The cost - side support for rubber remains. The news of state reserve sales has narrowed the price difference between RU and NR, suppressing futures prices in the short term. Before the end of September, rainfall in major producing areas may support rubber costs and limit the decline of rubber prices. The concentrated replenishment of downstream tire factories is over, and with a slight increase in domestic arrivals, the domestic inventory reduction is expected to slow down. The demand for downstream tires is in a seasonal peak, with an increase in tire factory operating rates and continuous raw material consumption, resulting in limited supply - demand contradictions. After the downstream purchasing demand subsides, rubber prices are expected to weaken, but the overall decline will be limited. For BR, the restart of maintenance devices will increase supply, and although the demand is in a peak season, the raw material demand has decreased after the concentrated restocking of tire factories. There are concerns about cost - side drag, but the large price difference with natural rubber still supports the price. Attention should be paid to the impact of geopolitical factors on the price of upstream butadiene raw materials [5][7] 3.

Strategy - For RU and NR, due to the narrowing of the price difference caused by the news of state reserve sales and the short - term suppression of futures prices, the cost - side support may limit the decline of rubber prices. After the end of the concentrated replenishment of downstream tire factories and with a slight increase in arrivals, the inventory reduction will slow down. Although the demand is in a peak season, after the purchasing demand subsides, rubber prices are expected to weaken, but the decline is limited [7] - For BR, the restart of maintenance devices will increase supply. Although the demand is in a peak season, the raw material demand has decreased after the concentrated restocking of tire factories. There are concerns about cost - side drag, but the large price difference with natural rubber still supports the price. Attention should be paid to the impact of geopolitical factors on the price of upstream butadiene raw materials [7]

Report Industry Investment Rating - The rating for RU and NR is neutral, and the rating for BR is also neutral [6] Core Viewpoints - For natural rubber, before the end of September, rainfall in the main producing areas may still cause disruptions, supporting the cost of rubber and limiting the decline of rubber prices. The concentrated restocking of downstream tire factories may be over, and with the slight increase in recent domestic arrivals, the domestic inventory reduction is expected to slow down. The demand for downstream tires has entered the seasonal peak season, the recent tire factory operating rate has rebounded, and the rigid consumption of raw materials continues, so the supply - demand contradiction is still not significant. After the downstream purchasing demand subsides, the rubber price is expected to weaken, but the overall decline space will be limited [6] - For BR, recently, the overhauled devices will be restarted one after another, and it is expected that the upstream operating rate will rise again, and the supply of BR will increase month - on - month. The demand side currently shows peak - season characteristics, and the tire factory operating rate has rebounded to the normal level. However, after the concentrated restocking of tire factories ends, the raw material demand has declined. The supply - demand situation shows signs of loosening month - on - month. Recently, there are concerns about cost - side drag on BR. Mainly, the weakening of crude oil prices may lead to an adjustment of butadiene prices. At the same time, the recent inventory of butadiene is at a moderately high level, and there may be pressure after the downstream restocking ends. It is expected that BR will show a weak pattern, but the large price difference with natural rubber still supports the lower price limit of BR [6] Market News and Data Futures - The closing price of the RU main contract was 15,620 yuan/ton, up 95 yuan/ton from the previous day; the NR main contract was 12,465 yuan/ton, up 70 yuan/ton; the BR main contract was 11,520 yuan/ton, up 90 yuan/ton [1] Spot - The price of Yunnan - produced whole latex in the Shanghai market was 14,800 yuan/ton, up 50 yuan/ton.

Report Industry Investment Rating - The investment ratings for RU and NR are neutral, and the rating for BR is also neutral [7] Core Viewpoints - For natural rubber (RU and NR), until the end of September, rainfall in major producing areas will continue to support rubber costs, limiting the downside of rubber prices. The concentrated replenishment of downstream tire factories may be over, and with a slight increase in recent domestic arrivals, the domestic inventory reduction is expected to slow down. Tire demand is in a seasonal peak, with recent increases in tire factory operating rates and ongoing raw material consumption, resulting in limited supply - demand contradictions. After the downstream purchasing demand subsides, rubber prices are expected to weaken, but the overall decline will be limited [7] - For cis - 1,4 - polybutadiene rubber (BR), recently shut - down plants will gradually restart, increasing the supply. The demand side shows peak - season characteristics, but raw material demand has declined after the concentrated replenishment of tire factories. Supply - demand is becoming more relaxed. There are concerns about cost drag, mainly due to the weakening of crude oil prices and high inventories of butadiene. BR prices are expected to weaken, but the large price difference with natural rubber will still support the downside [7] Market News and Data Futures - The closing price of the RU main contract was 15,525 yuan/ton, down 90 yuan/ton from the previous day; the NR main contract was 12,395 yuan/ton, down 30 yuan/ton; the BR main contract was 11,430 yuan/ton, down 75 yuan/ton [2] Spot - The price of Yunnan - produced whole latex in the Shanghai market was 14,750 yuan/ton, unchanged from the previous day.

Report Industry Investment Rating - RU and NR are rated neutral; BR is also rated neutral [6] Core View of the Report - The Fed's rate cut is in line with expectations, leading to an adjustment in commodities and relatively weak rubber prices this week. In the next one to two weeks, domestic rainfall is expected to decrease, but overseas production areas, mainly Thailand, are still affected by rainfall. It is expected that overseas raw material prices will remain firm, and the cost - side support for rubber may still be strong. The domestic arrival volume has slightly recovered, but the recent concentrated purchasing by downstream has led to a continuous decline in Qingdao port inventory in the past week. After the end of maintenance, the downstream tire operating rate has rebounded again, and the overall downstream demand shows a pattern of seasonal improvement. However, after the downstream restocking is completed, it is expected that there will still be pressure for the domestic port inventory to rise. For BR, there are concerns about cost - side drag recently, mainly due to the weakening of crude oil prices, which may lead to an adjustment in butadiene prices. At the same time, the butadiene inventory has gradually increased recently, and there may be pressure after the downstream restocking is completed. The fundamentals of BR itself still show a good pattern, and there are maintenance plans for several BR production facilities, which are expected to lead to a phased decline in supply. The downstream tire demand is in a peak season, with increased purchasing by tire factories, and the operating rate has rebounded after the end of maintenance. The large price difference with natural rubber also supports the BR price [6] Summary According to Related Catalogs Market News and Data - Futures: On the previous trading day's close, the RU main contract was at 15,570 yuan/ton, down 310 yuan/ton from the previous day; the NR main contract was at 12,300 yuan/ton, down 290 yuan/ton; the BR main contract was at 11,415 yuan/ton, down 175 yuan/ton. - Spot: The price of Yunnan - produced whole latex in the Shanghai market was 14,750 yuan/ton, down 350 yuan/ton from the previous day.
