Report Summary 1. Report Industry Investment Rating No information provided. 2. Core Viewpoints - For PTA, short - term geopolitical situation dominates the phased fluctuations of the energy - chemical sector. With crude oil supply disruptions leading to PX unit load reduction, cost support and expected supply decrease, while the demand side is cautious due to high costs. It is expected that the short - term PTA price will fluctuate widely following the cost side [3]. - For MEG, a large number of oil cracking units at home and abroad have reduced their loads, and the import of MEG to ports has sharply decreased due to restricted passage in the Strait of Hormuz. Supply has rapidly declined, and the main port inventory is expected to turn into de - stocking before the end of the month. The supply - demand situation will improve in the second quarter. Attention should be paid to overseas situations and unit changes [4]. 3.

Report Industry Investment Rating - Not mentioned in the report Core Viewpoints - The rubber market is influenced by macro - sentiment and supply - demand factors, with the price expected to maintain a wide - range oscillation pattern in the future. In the long - term, the market is regarded neutrally, and short - term drives from policies and events should be focused on [1]. - The Fed's rate - cut cycle is beneficial to the overall valuation of commodities. In December, the Fed cut interest rates by 25 basis points as expected, and the Fed Chairman's statement and weak US employment are favorable for future rate - cut expectations. China's monetary policy is stable, and there are few concerns about market liquidity. In the "15th Five - Year Plan" year, a series of policies may be introduced to promote investment, expand domestic demand, stabilize finance, and "combat involution", which will support the rubber valuation [1]. - The global total production capacity cycle has not fully peaked. Although the overall production growth rate is gradually slowing down, the supply in each production area still has elasticity. The increase in raw materials and imports has increased the supply pressure. Stable domestic demand growth requires continuous macro - incentives and actual implementation to build a stable demand expectation, and the export growth with high resilience still faces risks and challenges such as international situations and trade barriers [1]. Summary by Directory Chapter 1: Core Contradictions and Strategy Recommendations 1.1 Core Contradictions - Macro - sentiment is warm, driving up the overall performance of commodities, especially the non - ferrous metal sector. The financial attribute of RU is strong. With the approaching of the full - scale suspension of domestic production areas and the small number of warehouse receipts, it may be more significantly driven by the "catch - up" logic of valuation. The improvement of expectations has promoted the rise of the main contract, and the RU1 - 5 spread has回调 accordingly [1]. - The marginal reduction of natural rubber imports from Thailand has alleviated the supply - side pressure and supported the natural rubber price. The spot price is stable but the trading is dull, and the increase in rubber futures has led to a decline in the basis [1]. - The overall fundamentals of rubber are still under pressure. The dry storage of natural rubber has been continuously accumulating, and the supply pressure remains high. The contango structure of NR has deepened. The old full - latex is slowly de - stocking, and the ratio of light to dark inventory has been continuously rising [1]. - The supporting demand for automobiles is strong, but it is affected by the "trade - in" subsidy and the withdrawal of new - energy subsidies, which has led to retail promotions and demand front - loading. The subsequent growth may be under pressure. The tire start - up rate has declined, the downstream inventory pressure is high, and the trading sentiment is weak [1]. - Heavy trucks and construction machinery are boosted by new - old replacement and exports, but long - term fixed - asset investment and real - estate investment may continue to decline. Domestic demand growth is under pressure, and there is still uncertainty in exports, so long - term demand is suppressed [1]. 1.2 Trading - Type Strategy Recommendations - **Price Range**: The short - term reference oscillation range for RU2605 is 15,000 - 16,000, and for NR2602 it is 12,400 - 13,000 [22]. - **Trend Judgment**: Currently, the downstream demand is flat, and the upstream supply is neutral to loose. There are still supports and pressures in the range. With limited changes in fundamentals, the rubber price is greatly affected by macro - sentiment fluctuations. In the short - term, the bullish sentiment is strong, and the price is expected to maintain a wide - range oscillation pattern in the future [22]. - **Unilateral Strategy**: There are large differences between bulls and bears. It is advisable to wait and see at the current price, avoid chasing the rise, and pay attention to the upper pressure points [22]. - **Hedging Strategy**: It is expected that the volatility will be large. Unilateral trading can be combined with protective options or use spread strategies. It is advisable to sell options that are deeply out - of - the - money [22]. - **Basis Strategy**: The RU basis is at a high level, and the room for further increase may be limited. The valuation of full - latex may continue the seasonal repair trend, but the futures side may be affected by weak expectations [22]. - **Spread Arbitrage Strategy**: The far - month expectation of RU has improved, and the 1 - 5 spread turned negative last week. Currently, the small number of warehouse receipts is beneficial to the positive - spread arbitrage market under the near - month long position. However, the rubber price is under great pressure. During the suspension of domestic production in the first quarter of next year, the increase in the spread may be limited. Pay attention to the spread - regression arbitrage space [23]. - **Variety Arbitrage Strategy**: Pay attention to the opportunity to widen the RU - BR spread [23]. 1.3 Industrial Customer Operation Recommendations - **Price Range Forecast**: The price range forecast for rubber RU in the next two weeks is 15,000 - 16,000, with a current volatility (20 - day rolling) of 26.95% and a volatility historical percentile (3 - year) of 13.23%. For 20 - grade rubber NR, the price range is 12,000 - 13,000, with a current volatility of 13.13% and a volatility historical percentile of 68.66% [32]. - **Risk Management Strategy Recommendations**: For inventory management, when the inventory is high and there are concerns about price decline, short rubber futures (RU2605) can be used to lock in sales profits, with a hedging ratio of 50% and an advisable entry range of 16,000 - 16,200. Other strategies include buying out - of - the - money put options, selling call options, buying far - month rubber futures to lock in procurement costs, buying out - of - the - money call options, and selling put options according to different scenarios [32][33]. Chapter 2: Important Information and Concerned Events 2.1 Last Week's Important Information - **Positive Information**: The US GDP in the third quarter was 4.3% (+1.3%), and the core PCE price index annualized quarterly rate was 2.6%. The US economic growth exceeded expectations, which is beneficial to domestic demand. Thailand's natural rubber exports in November 2025 decreased, with a month - on - month decrease of 3.36 tons, a decline of 8.24%, and a year - on - year decrease of 3.4%. The EU's passenger - car market sales in November 2025 increased by 2.1%, and the cumulative sales from January to November increased by 1.4%. ANRPC predicted that the global natural rubber production in November 2025 would decrease by 2.6% to 147.4 tons, and consumption would decrease by 1.4% to 124.8 tons. Yunnan has stopped tapping, and Hainan is expected to stop tapping completely by the end of the month. There is still rain in southern Thailand, and the rainfall in Malaysia and Indonesia is continuously high, affecting raw material supply [35][36][37]. - **Negative Information**: The Chinese central bank kept the LPR unchanged in December. The US consumer confidence index in December was 89.1, slightly lower than expected. As of December 21, 2025, China's natural rubber social inventory was 118.2 tons, a month - on - month increase of 3 tons, an increase of 2.5%. The global light - vehicle sales in November 2025 decreased by 2.2% year - on - year. China's imports of natural rubber (including mixed rubber) in November 2025 increased by 13% year - on - year [38][39]. 2.2 This Week's Concerned Focus - Pay attention to the suspension progress of Hainan and overseas high - latitude production areas and the impact of winter phenology on production areas. Also, pay attention to the later rainfall in Malaysia and Indonesia [39]. - Focus on the progress of the new delivery standard's premium and discount rules for NR [5]. - Monitor the import and export of dry rubber and changes in social inventory, as well as the registration of full - latex warehouse receipts and the spot digestion progress [40]. - Keep an eye on downstream tire export data and tire start - up conditions [40]. - In terms of macro - aspects, pay attention to the overall sentiment of commodities, especially the change in the industrial product atmosphere. Pay attention to the official PMI data in China at the end of the month and the impact of the US initial jobless claims data on the interest - rate cut at the beginning of next year [40]. Chapter 3: Disk Interpretation 3.1 Price - Volume and Capital Interpretation - **Unilateral Trend**: Last week, due to the overall warm sentiment in the sector, the industrial product valuation was repaired. Rubber led the rise, reached a high point, and then maintained a narrow - range consolidation. However, it was still suppressed by fundamentals, resulting in increased differences between bulls and bears and increased positions [42]. - **Capital Movement**: From the perspective of profitable seats on the disk, the net short positions of Shanghai rubber and 20 - grade rubber increased significantly last week, indicating increased differences between bulls and bears in the market [45]. 3.2 Spot Market and Spread Analysis - **Spot Price Changes**: The prices of domestic full - latex, Thai RSS3, Vietnamese 3L, etc. all increased to varying degrees last week [48][49]. - **Delivery Product Price Trends**: The price difference between Thai and Malaysian standard rubbers and Indonesian standard rubbers has slightly narrowed. Currently, the rainfall in Malaysia and Indonesia has increased, and the northeastern part of Thailand may enter the winter suspension period in early 2026. It is expected that the spread will narrow in the short - term and then widen. NR is currently anchored to Indonesian standard rubber, but the revision of the delivery standard may lead to re - pricing [5]. - **Term Structure Analysis**: The basis of full - latex is maintaining the regression trend, and its performance is stronger than the historical level. However, last week, the futures expectation improved, and the basis of full - latex and smoked sheets to RU both回调. Due to strong weather disturbances in Indonesia, NR is anchored to the valuation of Indonesian standard rubber, and the futures have strengthened, resulting in a decline in the basis. As of last Friday, the forward premium of Thai - mixed rubber over Chinese - mixed rubber was about 65 yuan/ton [52]. - **Outer - Market Quotes**: The Japanese yen's strength due to Japan's interest - rate hike has suppressed the price of Japanese rubber, and the spread between RU and the Japanese smoked - sheet rubber futures 05 contract has widened. The price range of NR and Singapore standard rubber has oscillated [71]. - **Virtual - to - Physical Ratio and Sentiment Index**: Currently, the warehouse receipts of RU have increased, and the sentiment is warm, so the virtual - to - physical ratio has increased. The virtual - to - physical ratio of NR has remained stable, and the virtual - to - physical ratio of continuous contracts has changed little. Last week, the rubber sentiment was flat, and the downstream tire demand sentiment turned cold [78]. - **Variety Spread Analysis**: The relative valuation of full - latex spot has been continuously repaired, and the spread between it and Vietnamese 3L and Thai - mixed rubber has returned to the historical five - year range. Currently, the deep - colored rubber inventory is accumulating, while the light - colored rubber inventory is accumulating slightly slower. The ratio of light to dark inventory has been continuously rising, and the growth of RU warehouse receipts is slow, with less warehouse - receipt pressure. However, the spread between light and dark has回调. In the future, with the full - scale suspension of domestic production, the increase in overseas deep - colored rubber supply may drive the spread to widen [82]. Chapter 4: Valuation and Profit Analysis 4.1 Industry Chain Profit Tracking - **Raw Material Cost**: The prices of glue and cup - glue in Hainan increased last week. Yunnan has generally stopped tapping, and the price of available rubber blocks has remained stable. The weather in northeastern Thailand is relatively good, and the rainfall in southern Thailand has decreased, resulting in a decrease in the prices of glue and raw sheets [101]. - **Processing Profit - Domestic Rubber**: Yunnan has stopped tapping. Recently, the selling price of rubber blocks has remained stable, and the production profit of tire rubber increased last week [108]. - **Processing Profit - Imported Rubber**: With the increase in rubber prices last week, the profit of Thai smoked sheets increased slightly, and the profits of Thai standard and Thai - mixed rubbers increased significantly [110]. Chapter 5: Supply - Demand and Inventory Deduction 5.1 Supply Side - **Production in Major Producing Countries**: The production of natural rubber in major producing countries such as Thailand, Indonesia, Malaysia, and Vietnam shows certain seasonal characteristics [113]. - **Domestic Import Situation**: In November 2025, China imported 79 tons of natural and synthetic rubber in total, a month - on - month increase of 12.3 tons, an increase of 18%, and a year - on - year increase of 7.8 tons, an increase of 11%. From January to November this year, China imported 757.2 tons of natural and synthetic rubber (including latex), a year - on - year increase of 107.2 tons, an increase of 16.5% [114]. 5.2 Demand Side - **Total Demand in Major Producing Countries**: China's demand in November rebounded month - on - month, while the total demand in overseas major producing countries decreased month - on - month in October, and Malaysia remained flat [126]. - **Tire Production and Sales Situation**: The start - up rate of all - steel tires decreased last week, while that of semi - steel tire enterprises remained flat. Recently, the downstream trading has been dull, the inventory of all - steel tires has been accumulating rapidly, and the semi - steel tires are at a high - inventory level, with high inventory pressure. In November, the domestic tire production rebounded month - on - month but decreased slightly year - on - year. The exports of domestic tires rebounded month - on - month in November, with all - steel tires performing well and semi - steel tires showing an obvious seasonal decline, lower than the same period [128]. - **Replacement Demand**: The domestic logistics industry has been performing steadily this year. In November, the China Logistics Prosperity Index was 50.9%, a month - on - month increase of 0.2 percentage points. The domestic road freight rate index has remained stable, lower than the end - of - 2024 level. The road freight turnover has rebounded, with the year - on - year growth rate remaining flat, and the passenger turnover has slightly declined, slightly lower than the same period. The Shenwan Road Freight Industry Index shows that road freight has rebounded compared with last week and is generally at a high level. The long - term slowdown of domestic fixed - asset investment and the further decline of real - estate investment may suppress the growth of total replacement demand in freight logistics [133]. - **Supporting Demand - Automobiles**: With the multiple stimuli of government subsidies, automobile - enterprise discounts, and interest - subsidy policies, the domestic supporting demand may maintain resilience. In November, the sales of domestic passenger cars decreased month - on - month but were higher than the same period in 2024. The sales of commercial vehicles were strong, with six consecutive months of year - on - year growth, and the growth rate in November increased month - on - month. The exports of automobiles reached a new high, with both passenger cars and commercial vehicles maintaining a year - on - year growth trend. The inventory pressure of automobile dealers has increased, and the inventory of passenger cars has increased significantly, higher than the same period and the historical average, indicating a decrease in the inventory turnover rate of passenger cars and a significant increase in the inventory coefficient, with high terminal inventory pressure [141]. - **Supporting Demand - Heavy Trucks and Construction Machinery**: The production of heavy trucks has maintained high growth this year, and the sales in November further increased month - on - month, reaching a five - year high. The sales of new - energy heavy trucks declined in October, leading to a slowdown in the overall growth rate. The cumulative year - on - year growth of the domestic and export sales of construction machinery in November increased to 11.6%, with exports maintaining stable growth and domestic sales maintaining high growth. In the long - term, the weak performance of domestic fixed - asset investment and the slowdown of domestic real - estate and infrastructure construction may limit the growth of new demand for trucks, and the tire - supporting demand brought by them is expected to have limited growth. In 2026, the replacement demand will remain at a high level, and industry - standard policies such as national - standard updates and trade - ins may stimulate the accelerated replacement of trucks, especially pure - electric trucks [144]. - **Overseas Tire Production**: Japan's tire production has been generally stable this year, with all - steel tires performing strongly, semi - steel tires showing a slight year - on - year increase. Thailand's tire shipment index has shown year - on - year growth this year, but it was affected by holidays and tariff wars in April. The strong international demand and the effect of rush - exporting have promoted a seasonal increase. The performance in the third and fourth quarters was weak, and it declined significantly in October, lower than the same period, and is expected to maintain a seasonal trend in the future [146]. - **Overseas Tire Demand**: The year - on - year performance of US automobile sales is weak, but tire imports have increased against the trend. Due to the unsmooth reshoring of US manufacturing and the improvement of international trade relations, it is expected that the US tire import demand will not decrease, and the resistance to China's tire exports to the US may decrease, but sudden trade barriers still need to be vigilant. The production and sales of European passenger cars have been performing steadily, with an obvious rebound in the peak season. The registration volume in October maintained year -

A 300,000 - ton/year synthetic gas - to - ethylene glycol device in Shanxi is restarting, and a cracking device in Singapore has an unexpected delay in restart. The demand improvement brings positive support, and the supply has shrunk due to device overhauls. The prices of PX and TA follow cost fluctuations, and the ethylene glycol price is favorable due to reduced imports and lower inventory [4][5] - **Rubber**: On Wednesday, RU2601 fell 125 yuan/ton to 15760 yuan/ton, NR fell 175 yuan/ton to 12615 yuan/ton, and BR fell 135 yuan/ton to 11710 yuan/ton. From January to July, Vietnam's total exports of natural rubber and mixed rubber decreased by 0.8% year - on - year, but exports to China increased by 5% year - on - year. The supply - side prices of cup rubber and latex are relatively firm, and the demand - side tire exports have increased, supporting the short - term price to oscillate [5] - **Methanol**: The spot price in Taicang is 2250 yuan/ton. Recently, there have been many domestic device overhauls, and the supply is at a phased low. Overseas, Iranian device loads are high, and short - term arrivals will remain high. However, with the increase in the price difference between Europe, India, and China, the arrival volume will decrease in the long - term. The MTO device load in East China is not high, and the port inventory will increase in the short - term. The price is expected to oscillate [5][7] - **Polyolefins**: The mainstream price of East China wire - drawing PP is 6910 - 7080 yuan/ton. The production profit of different raw material - based PP varies.
