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.

Report Summary 1. Report Industry Investment Rating No information provided. 2. Core Views - Global natural rubber producing areas are in the tapping season. In Yunnan, improved weather and continuous raw material supply pressure support a slight price increase. In Hainan, with better weather, tapping operations resume, and raw material supply shows a seasonal increase. Some processors' raw material replenishment enthusiasm increases due to improved profits and orders [2]. - Recently, Qingdao port's natural rubber inventory continues to decline, though the decline rate slows. The inflow increases while the outflow increase is moderate. Downstream tire enterprises' procurement is relatively mild, and they continue the on - demand procurement rhythm. Short - term Qingdao port inventory is expected to continue a slight decline [2]. - In terms of demand, most semi - steel tire enterprises' equipment ran stably last week, but some had maintenance due to high shipment pressure, dragging down overall capacity utilization. All - steel tire enterprises' equipment ran stably, mostly continuing the previous production control state. Some enterprises had maintenance plans at the beginning of this month, which may still affect short - term capacity utilization. The ru2601 contract is expected to fluctuate in the 15650 - 16200 range, and the nr2510 contract is expected to fluctuate in the 12520 - 13000 range [2]. 3.

Report Summary 1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints - The utilization rate of domestic tire production capacity fluctuated slightly last week. Some large semi-steel tire enterprises had about one - week maintenance, dragging down the overall enterprise production capacity utilization rate. The full - steel tire maintenance enterprises resumed work, driving up the full - steel tire production capacity utilization rate. There is still a slight upward space for the production capacity utilization rate as the maintenance enterprises gradually resume work, but the overall order performance is average, and enterprises will continue to control production, which will limit the increase in the overall production capacity utilization rate.
