1. Report Industry Investment Rating No relevant content provided. 2. Report's Core View - The current oil price has been relatively undervalued, and its static fundamentals and dynamic forecasts remain favorable. It is a good opportunity for left - side layout. If the geopolitical premium re - emerges, the oil price will have more upside potential [3]. - For methanol, the valuation is still high, downstream demand is weak, and the price is under pressure. It is recommended to wait and see or short it within the sector when the price is high [5]. - For urea, although the current domestic demand is weak, the overall valuation is low, and the room for further decline is limited. It is advisable to go long at low prices and wait for potential positive factors [7]. - For rubber, a neutral approach is recommended for the short - term high - rising rubber price, with quick in - and - out operations. One can also consider a band - trading strategy of going long on RU2601 and shorting on RU2509 [11]. - For PVC, the supply is strong, demand is weak, and the valuation is high. The fundamentals are poor, and it is necessary to observe whether exports can reverse the domestic inventory build - up situation. The price may decline significantly after the anti - involution sentiment fades [11]. - For styrene, the BZN spread is expected to repair in the short term. After the high - level port inventory is reduced, the styrene price may oscillate upwards following the cost side [13][14]. - For polyethylene, the short - term price will be determined by the game between the cost side and the supply side. It is recommended to hold short positions [16]. - For polypropylene, the cost side will likely dominate the market, and the price is expected to follow the oil price and oscillate upwards [17]. - For PX, the load remains high, and it is expected to continue de - stocking. The valuation has support at the bottom but limited upside in the short term. One can consider going long following the oil price when the peak season arrives [19][20]. - For PTA, the supply is expected to continue building up inventory, and the processing fee has limited room for operation. One can consider going long following PX when the downstream performance improves in the peak season [21]. - For ethylene glycol, the fundamentals will turn from strong to weak, and the short - term valuation may decline [22]. 3.

1. Report Industry Investment Rating - Not mentioned in the provided content 2. Core Viewpoints of the Report - The rubber sector continued to strengthen with the macro - environment this week, showing a pattern of widespread simultaneous rises and falls among commodities. The volatility of the rubber sector reached a 5 - year high under the dual drive of the macro - environment and events. Attention can be paid to the strategy of shorting volatility. The market may return to the fundamentals of limited improvement after the macro - sentiment fades [3][5]. - The supply of synthetic rubber has become slightly looser, with a slight increase in the production of butadiene rubber and a slight decrease in the production of semi - steel tires [4]. - Some macro data, such as the CSI 1000 Index and the Citi G10 Economic Surprise Index, are favorable for the unilateral trend of RU, while the supply data of natural rubber shows that only the price of smoked sheet rubber has slightly stabilized and rebounded, and the fundamentals for a recovery are not solid [5]. - The conflict between Thailand and Cambodia has affected the market, but the market mainly followed the macro - strengthening logic after a short - term reaction to the potential supply tightening. If the domestic macro - drive weakens next week and the conflict escalates, it may become the main contradiction again [5]. - The mixed basis is bearish and has not been affected by the macro - warming. The supply of natural and synthetic rubber has certain changes, which has an impact on the trend of RU [27][37]. 3. Summary by Related Catalogs 3.1 Macro - related Data - The CSI 1000 Index closed at 6476 points, reaching a new high since January 2016. The average value in the past 6 months increased by +19.9% year - on - year, with the increase expanding for 12 consecutive months, which is favorable for the unilateral trend of RU [5][18]. - The Citi G10 Economic Surprise Index reported +12.4 points, with the average value in the past 6 months increasing by +6.6 points year - on - year, and the increase expanding for 2 consecutive months, which is also favorable for the unilateral trend of RU [5][18]. 3.2 Impact of the Thailand - Cambodia Border Conflict - Four Thai provinces affected by the conflict account for about 7% of Thailand's total rubber production. In 2024, the total rubber production of these four provinces was 34.1 tons, accounting for 7.1% of Thailand's total production of 478.9 tons. Cambodia's total production in 2024 was 40.7 tons [20][22]. - The RU - NR spread is a good indicator to reflect the impact of the Thailand - Cambodia border conflict. Currently, NR is relatively weak compared to RU, but the conflict is expected to suppress the supply of 20 - grade rubber and make NR relatively stronger. The spread started to move before the unilateral increase on July 24, confirming the supply logic in advance [25][26]. 3.3 Mixed Basis and Supply - demand Factors - In May, the total import volume of standard and mixed rubber from Thailand, Malaysia, and Indonesia decreased for 2 consecutive months, but the average import volume in the past 6 months increased by +10.1% year - on - year, with the marginal increase for 10 consecutive months, which is bearish for the mixed rubber [28]. - In June, the total import volume of natural and synthetic rubber in China decreased for 3 consecutive months, reaching 60.0 tons. The production of synthetic rubber increased month - on - month, reaching 70.3 tons, and the production of natural rubber increased for 3 consecutive months in May, reaching 9.7 tons. The total of these is 140.0 tons, with the cumulative volume in the past 3 months increasing by +9.3% year - on - year, and the increase narrowing for 2 consecutive months, which is favorable for the unilateral trend of RU [37]. 3.4 Synthetic Rubber Supply - The capacity utilization rate of domestic butadiene increased to 70.0%, with the average capacity utilization rate in the past 5 weeks increasing by +2.3% year - on - year, and the marginal decrease for 4 consecutive weeks. The capacity utilization rate of domestic high - cis butadiene rubber increased to 67.6%, with the average capacity utilization rate in the past 5 weeks increasing by +9.4% year - on - year, showing a marginal increase [49]. - The port inventory of domestic butadiene decreased for 2 consecutive weeks, reaching 1.57 tons, with the average inventory in the past 5 weeks increasing by +0.21 tons year - on - year, and the marginal decrease for 4 consecutive weeks. The total inventory of domestic butadiene rubber in traders and factories is 3.23 tons, with the average inventory in 5 weeks increasing by +0.90 tons year - on - year, and the marginal decrease for 4 consecutive weeks [49]. 3.5 Tire Consumption - The production line operating rate of domestic all - steel tires decreased to 65.0%, with the average operating rate in the past 12 weeks increasing by +3.9% year - on - year, and the marginal increase for 9 consecutive weeks. The finished product inventory of all - steel tires remained unchanged at 41 days, with the average inventory in 24 weeks decreasing by - 2.7% year - on - year, and the marginal decrease for 53 consecutive weeks [60]. - The production line operating rate of domestic semi - steel tires decreased to 75.9%, with the average operating rate in the past 24 weeks increasing by +3.4% year - on - year, showing a marginal decrease. The product inventory of semi - steel tires increased by 1 day to 47 days, with the average inventory in the past 24 weeks increasing by +36.5% year - on - year, and the marginal decrease for 9 consecutive weeks [60]. 3.6 NR Month - spread - The daily average open interest of the NR contract is equivalent to 115.90 tons, the warehouse receipt volume is 3.48 tons, and the virtual - to - real ratio is 32.30 times. Since the virtual - to - real ratio lags behind the month - spread, it is expected that the decline in the open interest of the NR contract will be greater than the reduction in warehouse receipts in the later period [65]. - From a long - term perspective, the NR month - spread may strengthen until September, and there is a large expectation of weakening after that (the near - month contract weakens). Attention can be paid to the opportunity of reverse arbitrage when the month - spread weakens [65].

Group 1 - The core viewpoint indicates that the domestic rubber market is experiencing a rebound in sentiment due to expectations of interest rate cuts by the Federal Reserve and domestic "anti-involution" policies, with natural rubber prices rising to 14,400 yuan per ton as of July 11, an increase of 400 yuan since July 8 [1] - The current price increase is primarily driven by "anti-involution" sentiment, which may continue to boost market sentiment in the short term; however, due to expectations of increased supply both domestically and internationally, and high current inventory levels, the fundamental weakness may prevent sustained price increases [1][2] - The rubber production areas are seeing normal harvesting conditions this year, with improved weather in Hainan and increased output expected from Thailand and Vietnam, contributing to a more relaxed supply outlook [2] Group 2 - In June, the estimated import volume of natural rubber was 481,500 tons, an increase of 28,000 tons month-on-month; meanwhile, domestic inventory levels showed a slight decrease, continuing a trend of shallow declines and deep increases [3] - The demand seasonality is evident, with a notable decline in the operating rate of semi-steel tires, which fell by 3.28 percentage points year-on-year to 75.49% in Q2; some tire manufacturers are planning maintenance or reducing output due to inventory pressures [4] - The foam industry is also experiencing weak demand, with many factories operating at low capacity and cautious raw material procurement due to downgraded consumer sentiment [5] Group 3 - The profit margins in the natural rubber industry are under pressure due to multiple factors including increased supply, weak demand, and rising inventory levels, particularly affecting processors and traders [6] - As of July 10, the theoretical production cost of Hainan's natural rubber was 13,720 yuan, up 280 yuan from the previous week; however, due to weak demand, the high-price procurement sentiment has cooled, leading to a decline in purchase prices and profits [7] - The compression of profit margins is likely to weaken procurement willingness among enterprises, resulting in downward pressure on raw material prices, with the contradiction between lack of cost support and weak demand further pushing the market into narrow fluctuations [7]
