Report Industry Investment Rating - The investment rating for RU and NR is neutral [11]. - The investment rating for BR is neutral [11]. Report's Core View - The support for natural rubber is still at the cost - end. The conflict in Thailand and Cambodia and the rain in southern Thailand may support the raw material prices, but the overall supply is increasing. Domestic port inventory is expected to rise further, and downstream tire orders are in the off - season, resulting in weak supply - demand drivers [11]. - For cis - butadiene rubber, supply remains abundant. Downstream tire orders are in the off - season, with weak supply - demand drivers. The stable price of upstream butadiene raw materials provides some cost support [11].

Strategy - For RU and NR, maintain a neutral view. The support for natural rubber comes from the cost - end. The conflict in Thailand and Cambodia and the rain in southern Thailand are expected to keep the raw material prices in Thailand firm this week. However, the overall supply is increasing, and the domestic port inventory is expected to rise. The downstream tire orders are in the off - season, so the supply - demand drivers are weak [11]. - For BR, maintain a neutral view. Yulong Petrochemical has restarted, and only Maoming Petrochemical is under maintenance, which is expected to restart in mid - January. The supply of cis - butadiene rubber remains abundant. The downstream tire orders are in the off - season, with weak supply - demand drivers. The stable price of upstream butadiene raw materials provides some cost support [11].

Report Industry Investment Rating - The rating for RU and NR is neutral, and the rating for BR is also neutral [10] Core Viewpoints - For natural rubber, recent cooling in China may accelerate the end of the tapping season in Yunnan, reducing the output of RU deliverable products. Hainan has good weather with expected raw material growth. Thailand's northern region is in the peak production season, but the south is affected by rainfall, limiting glue output. Cup - rubber production may increase. Domestic dark - colored rubber may continue to accumulate inventory. Downstream demand lacks highlights, and the upside potential of tire factory operating rates is limited. The supply - demand structure may favor the widening of the spread between RU and NR and the reverse - arbitrage logic of NR, with prices moving in a range [10] - For cis - butadiene rubber, some upstream devices have changes such as restarts and shutdowns for maintenance. The supply is expected to remain abundant as private enterprises' production profits improve and operating rates rise. Downstream demand lacks highlights, and the upside potential of tire factory operating rates is limited. The price of upstream butadiene is expected to be weak due to inventory pressure [10] Summary by Related Catalogs Market News and Data - Futures: On the previous trading day, the closing price of the RU main contract was 15,320 yuan/ton, up 80 yuan/ton from the previous day; the NR main contract was 12,275 yuan/ton, down 10 yuan/ton; the BR main contract was 10,395 yuan/ton, up 10 yuan/ton [1] - Spot: The price of Yunnan - produced whole latex in the Shanghai market was 14,900 yuan/ton, up 100 yuan/ton.
