Core Viewpoint - The overall production load of soda ash manufacturers is low due to maintenance activities, leading to a mixed performance between light and heavy soda ash prices [1] Group 1: Production and Maintenance - Several manufacturers, including Fengcheng Salt Chemical, Xiangyu Salt Chemical, and China Salt Kunshan, are undergoing maintenance, resulting in reduced production capacity [1] - Key soda ash production facilities in Henan, Tianjin, Shaanxi, Hunan, and Huainan are also experiencing maintenance, contributing to the overall low operational load [1] Group 2: Market Demand and Pricing - The demand for light soda ash remains stable, with tight supply in the central and eastern regions, leading to a strong pricing sentiment among manufacturers [1] - Most manufacturers have filled their orders for the month, indicating a robust market for light soda ash [1] - In contrast, the demand for heavy soda ash is weak, with futures prices declining and a noticeable price advantage for futures sources, resulting in increased transaction volumes for heavy soda ash [1] - The transaction price focus for heavy soda ash has shifted downward due to these market dynamics [1]

1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views of the Reports Polyolefins - PP shows a pattern of both supply and demand growth, with reduced maintenance leading to increased supply and a slight accumulation of inventory under the pressure of new production capacity. PE shows increased supply and decreased demand. Although unplanned maintenance eases some supply pressure, imported goods are abundant, and demand is generally weak except for agricultural films. The inventory of hedging merchants is gradually decreasing, the basis is strengthening, and inventory is being cleared. When the price is below 6800, the downstream's willingness to buy increases. The cost side is affected by the shock of crude oil and the strength of coal, and the PDH profit has continued to weaken this week. [2] Methanol - In the domestic market, Baofeng continues to purchase externally, and Jiutai has an unexpected maintenance. The domestic production will continue to increase. Currently, the marginal devices in the domestic market have suffered losses. In the port market, the gas restriction in Iran has been postponed, and the shipment has accelerated. As of November 19, Iran has shipped 885,000 tons, putting significant pressure on the port methanol market. With high inventory and the profit of imported methanol from Iran, the willingness to hold goods has weakened, and the price has declined while the basis remains stable. The demand side is based on rigid procurement. The market is currently trading on the logic of "weak reality", and the core contradiction lies in the high inventory in the port. The inventory contradiction of the 01 contract cannot be resolved, and the weak reality will continue to be traded before the gas restriction in Iran. [4] Glass and Soda Ash - Soda ash: The market has returned to a weak state, and the overall pattern of oversupply is still prominent. Fundamentally, the weekly production remains at a high level of around 750,000 tons, and the oversupply is obvious compared with the current rigid demand. The inventory of manufacturers has been transferred to the middle and lower reaches, and the trade inventory has continued to rise. In the medium term, there is no expectation of a significant increase in downstream production capacity, so the overall demand for soda ash will continue the previous rigid demand pattern. If there is no actual production capacity exit or load reduction in the future, the supply - demand situation will be further pressured. - Glass: The spot sales have strengthened, and the high sales rate in some regions has continued to be above 100%. Consecutive price cuts have driven the middle and lower reaches to purchase. Although 4 production lines in the Shahe area were cold - repaired last week, there will be production lines restarting and igniting in the future, which will put pressure on the supply side. The latest deep - processing order days have improved slightly, and there is still some rigid demand support in the short term as November is the peak season for year - end rush work. However, in the medium and long term, at the end of the peak season, the market is worried about the sustainability of future demand. As the temperature in the north drops, outdoor construction will gradually stop, and the demand side will shrink after December, putting pressure on the glass price. The real estate is still in the bottom cycle, and the completion volume has decreased significantly. Therefore, in the oversupply pattern, the glass industry still needs to clear production capacity to solve the oversupply dilemma. [7] PVC and Caustic Soda - Caustic soda: The supply - demand situation of the caustic soda industry still faces certain pressure. The purchasing enthusiasm of the main downstream alumina has decreased, so the support from the main demand side of caustic soda is weak, which suppresses the caustic soda price upwards. During the northern environmental protection control period, some alumina plants may have production reduction expectations. There is an overhaul expectation in the East China region, and the supply will decrease slightly. The price in this region may be relatively stable due to certain rigid demand support, but in the long term, the supply - demand still has pressure. The non - aluminum market is still sluggish, and overall, the supply - demand pressure is still relatively large. It is expected that the caustic soda price will fluctuate weakly. - PVC: The PVC spot market continues to fluctuate weakly. This week, maintenance and partial device load reduction have led to a decrease in production on a month - on - month basis, but it is still at a high level. Affected by local logistics, the market arrivals have decreased, and the social inventory has decreased on a month - on - month basis. Next week, the supply - side operating rate will increase. The demand side is in the traditional off - season from November to January of the next year. As the outdoor construction in the north gradually decreases in winter, the overall real estate demand reduction still has a negative impact. In terms of exports, India has officially cancelled the BIS certification for imported PVC issued in 2024, which is beneficial for domestic PVC to enter the Indian market. However, there is an expectation of anti - dumping duties, and the Asian contract price for December is still to be observed next week. It is expected that the external demand will be difficult to increase. The overall demand side has limited support for PVC. The supply - demand is still in an oversupply pattern, and it is difficult for the price to form an upward drive. It is expected to continue the weak pattern at the bottom. [8] Natural Rubber - The supply side: Yunnan has encountered cold weather, which has accelerated the end of the tapping season in Yunnan. The rainy season in southern Thailand continues, and the price of overseas raw materials is high, which strongly supports the rubber price. The demand side: Currently, the overall demand is weak. Channels are cautious in purchasing and mainly focus on digesting inventory. Next week, the purchasing enthusiasm of some agents on an as - needed basis may increase slightly, which will drive the overall sales volume. However, the overall demand is weakening, and the actual increase in purchasing volume is limited. The market still mainly focuses on digesting inventory. In conclusion, the natural rubber inventory has entered the seasonal inventory accumulation period, and the terminal demand support is insufficient. There is an expectation that the operating rate of downstream enterprises will further decline. It is expected that the natural rubber market will enter a range - bound consolidation. In the future, attention should be paid to the raw material output in the peak production season of the main producing areas and macro - level changes. If the raw material supply is smooth, the rubber price is expected to decline. If the raw material supply is not smooth, the rubber price is expected to operate in the range of 15,000 - 15,500. [9] Pure Benzene and Styrene - Pure benzene: Recently, many sets of pure benzene devices have overhaul expectations, but the import expectation remains high, and the overall supply may still be relatively loose. On the demand side, the load of downstream styrene has increased due to the restart of some devices, but some loss - making varieties have reduced production to maintain prices, and the domestic demand side has limited support. The port inventory has increased, and there are still many arrivals in the future, so the supply pressure of pure benzene is relatively large. After the overhaul of the disproportionation device in the US Gulf ends, the support from blending oil may weaken, but South Korea's aromatics have an export expectation to the US, and the US dollar price of pure benzene has increased. Overall, the supply - demand expectation of pure benzene is still relatively loose, and the limited support from the cost side may limit the upward space. It may fluctuate and consolidate. However, since the current valuation of pure benzene is low, future attention should be paid to device changes. In the short term, it is advisable to wait and see for BZ2603. - Styrene: After the overhaul of the disproportionation device in the US Gulf ends, the blending oil demand may weaken. However, in November, the supply - demand situation of styrene has further improved. With the South Korean mixed aromatics trading, styrene has an export transaction expectation, and the port inventory has decreased. There are positive factors supporting styrene, and it will mainly fluctuate and repair in the short term. However, as the profit of styrene is repaired, the overhaul of some factories may be delayed. Coupled with the trial operation of new devices and the expected weakening of downstream EPS demand, it is expected that the upward space of styrene will be limited. In the short term, the price of EB01 may mainly fluctuate and consolidate. [10] Polyester Industry Chain - PX: Recently, the operating loads of Asian and domestic PX have decreased. However, the supply of Asian MX is abundant, and some factories rely on MX to supplement PX production, so the PX supply still remains at a relatively high level. On the demand side, the PTA price still has certain support this week. However, the spot floating price and monthly spread of PX are still weak, and the overall support from oil prices is limited. It is expected that the rebound space of PX is limited. Strategically, PX should be regarded as a short - term high - level shock. - PTA: As two PTA devices in East China are gradually under maintenance, the basis has slightly strengthened. According to the balance sheet, the supply - demand of PTA is in a tight balance in November, but the supply - demand of PTA is expected to be relatively loose from December to the first quarter of next year, and the upward drive of the basis is limited. In terms of absolute price, recently, the absolute price of PTA is relatively strong due to the support of blending oil demand and India's cancellation of BIS certification. However, the overall support from oil prices is limited, and the rebound space of PTA is still limited. Strategically, TA should be regarded as a short - term high - level shock, and TA1 - 5 should be treated as a rolling reverse spread. - Ethylene glycol: The operating load of ethylene glycol is at a high level. The arrival of overseas ethylene glycol shipments is relatively concentrated in November, and the port inventory will continue to increase recently, and the basis will weaken. In addition, the inventory accumulation amplitude of ethylene glycol from November to December is expected to be relatively high, and the upward pressure on ethylene glycol is significant. Strategically, the seller of the out - of - the - money call option with an exercise price of no less than 4100 for EG2601 should hold, and EG1 - 5 should be reversely spread at high levels. - Short - fiber: Although the spot processing margin of short - fiber has been significantly compressed recently, there is still profit at present, and the inventory pressure of short - fiber factories is not large, so the short - fiber supply remains at a high level. On the demand side, the terminal demand has seasonally weakened in November. In addition, the cancellation of India's BIS certification has certain benefits for PTA and filament, but has relatively little impact on short - fiber. Therefore, under the short - term weak supply - demand expectation and cost - side support, it is expected that the absolute price of short - fiber will be under pressure, and the processing margin still has room for compression. Strategically, the unilateral strategy is the same as that of PTA; the processing margin on the disk should be shorted at high levels. - Bottle - grade polyester: In mid - November, the Huarun device has both maintenance and restart. In addition, according to Longzhong Information, the commissioning of the new device of Dongying Fuhai has been postponed, and the domestic supply has not changed much. Considering that November is in the off - season of demand and the window period between the Spring Festival stocking, the demand side has insufficient support for bottle - grade polyester. The supply - demand of bottle - grade polyester remains in a loose pattern. Therefore, the social inventory of bottle - grade polyester will probably enter the seasonal inventory accumulation channel, and PR will mainly fluctuate with the cost side. The processing margin of PR is limitedly boosted by supply - demand and will change dynamically with the raw material cost. Strategically, the unilateral strategy of PR is the same as that of PTA; the processing margin of the main contract of PR is expected to fluctuate in the range of 300 - 450 yuan/ton. [12] Crude Oil - Overnight, affected by the news that Russia and Ukraine may restart peace talks, the geopolitical premium has declined, and the oil price has declined under pressure. However, EIA data shows that the US crude oil inventory has decreased more than expected, and the decline of the oil price has been slightly narrowed. Recently, attacks or sanctions caused by the Russia - Ukraine issue have had a short - term impact on the oil price. However, under the pressure of continuous production increase by OPEC+ and the record - high US crude oil production, the supply - demand pattern of crude oil is still weak, and the upward pressure on the oil price is significant. In the short term, attention should be paid to the support of Brent crude oil at $60 per barrel and the geopolitical dynamics between Russia and Ukraine. [14] 3.

Report Industry Investment Rating No relevant content provided. Core Viewpoints - Overall, finished steel products are supported by raw material costs at the lower end, but their upward drive is suppressed by inventory and demand. They are expected to trade in a range, with rebar likely between 2900 - 3200 and hot - rolled coil between 3100 - 3400. Attention should be paid to the de - stocking speed and downstream consumption, and the risk lies in the possible negative feedback caused by the decline in steel enterprise profitability [3]. - The iron ore fundamentals show a pattern of strong supply and weak demand, with total inventory continuously increasing, but a structural shortage of deliverable products. The price lacks a strong trend driver. The port inventory is accumulating above the seasonal level, but the inventory of deliverable brand coarse powder is decreasing, supporting the basis to strengthen. The coking coal price decline provides a seesaw support for the ore price, but the subsequent recovery of coking coal valuation may squeeze the iron ore [21]. - In the short term, the coal - coke futures and spot prices may face adjustment pressure due to factors such as the high spot price increase, weak downstream acceptance, and seasonal weakening of demand. In the long - term, the supply elasticity of coking coal will be restricted by policies, and the winter storage demand is expected to limit the downward space of coking coal prices [31]. - Ferroalloys face a fundamental situation of high inventory and weak demand. Although the cost center may shift down due to the impact of energy supply - guarantee policies on coking coal prices, the downward space is limited, and they are expected to fluctuate weakly [44]. - Soda ash is mainly priced by cost. Without production cuts, its valuation has limited upward elasticity. The medium - and long - term supply is expected to remain high, and the upper - and middle - stream inventory is high, restricting the price, but there is cost support at the lower end [53]. - The glass market has weak production and sales recently, and the high inventory in the middle stream brings significant spot pressure. The 01 contract may decline towards the delivery date, but there is cost support and policy expectations in the long - term [77]. Summary by Directory Steel - **Price Data**: On November 19, 2025, the closing prices of rebar 01, 05, and 10 contracts were 3070, 3116, and 3162 respectively; those of hot - rolled coil 01, 05, and 10 contracts were 3277, 3281, and 3298 respectively.

Group 1: Polyolefin Industry Core View PP shows a pattern of both supply and demand growth, with reduced maintenance driving supply recovery and inventory slightly accumulating under new - capacity pressure; PE shows increased supply and decreased demand. The market is in an oversupply situation, and it is recommended to gradually stop losses and reduce positions on previous short positions near the previous low, with limited expected rebound space [2]. Summary by Catalog - **Price and Spread**: On November 18, compared with November 17, L2601, L2605, PP2601, and PP2605 closing prices all declined, with L15 and PP15 spreads also decreasing. Spot prices of some products like East China PP filament and North China LDPE decreased, while North China LL basis and East China pp basis increased [2]. - **Inventory and开工率**: PE downstream weighted开工率 decreased by 0.80%, PE enterprise inventory increased by 7.96%, and social inventory decreased by 1.86%. PP装置开工率 increased by 2.28%, and downstream weighted开工率 increased by 0.3% [2]. Group 2: Methanol Industry Core View The inland market has increasing output, and marginal devices are in loss. The port methanol market is under pressure due to high inventory and increased Iranian shipments. The market is trading on the "weak reality" logic, and the inventory contradiction of the 01 contract cannot be resolved before Iranian gas restrictions [4]. Summary by Catalog - **Price and Spread**: On November 18, compared with November 17, MA2601 and MA2605 closing prices increased slightly, while MA15 spread decreased. Some regional spot prices changed slightly, and regional spreads also changed [4]. - **Inventory and开工率**: Methanol enterprise inventory decreased by 4.44%, port inventory increased by 3.80%, and social inventory increased by 2.10%. Upstream domestic and overseas enterprise开工率 increased slightly, while downstream - outer - purchased MTO装置开工率 decreased by 2.38% [4]. Group 3: Ester Industry Chain Core View PX supply remains at a relatively high level, and demand support is weak. PTA supply - demand is expected to be loose in the future, and its rebound space is limited. Ethylene glycol will see inventory accumulation, and its price is under pressure. Short - fiber supply is high, and demand is weak. Bottle - chip supply - demand is in a loose pattern [7]. Summary by Catalog - **Price and Spread**: On November 18, compared with November 17, prices of some upstream products like Brent crude oil increased, while prices of some downstream polyester products decreased. PX - related spreads and PTA - related spreads also changed [7]. - **Inventory and开工率**: MEG port inventory increased by 10.7%. Asian and Chinese PX开工率 decreased, PTA开工率 decreased slightly, and polyester综合开工率 decreased by 0.9% [7]. Group 4: Crude Oil Industry Core View The continuous attacks on Russian refineries and sanctions have increased concerns about crude oil supply, which has boosted oil prices in the short term. However, under the pressure of OPEC + continuous production increase and high US crude oil production, the crude oil supply - demand pattern is still weak, and the rebound space of oil prices is limited. Short - term Brent crude oil may fluctuate in the range of $60 - 66 per barrel [9]. Summary by Catalog - **Price and Spread**: On November 18, compared with November 17, Brent, WTI, and SC prices increased. Spreads such as Brent M1 - M3, WTI M1 - M3, and SC M1 - M3 also changed [9]. - **Product Price and Spread**: Prices of NYM RBOB, NYM ULSD, and ICE Gasoil increased, and their M1 - M3 spreads also increased [9]. - **Crack Spread**: Some crack spreads such as US gasoline and European gasoline changed, with US diesel and Singapore diesel crack spreads increasing significantly [9]. Group 5: Natural Rubber Industry Core View Supply - side factors support rubber prices, but overall demand is weak. The market is expected to enter range - bound consolidation, and attention should be paid to raw material output in the peak - production season of major producing areas and macro - level changes [10]. Summary by Catalog - **Price and Spread**: On November 18, compared with November 17, the price of Yunnan state - owned full - latex increased slightly, and the full - latex basis increased. Some raw material prices changed slightly [10]. - **Fundamental Data**: September production in Thailand, Indonesia, etc. changed. Tire开工率 of semi - steel and full - steel decreased slightly, and October domestic tire production decreased [10]. - **Inventory Change**: Bonded - area inventory and natural rubber factory - warehouse futures inventory increased, while the出库 rate of dry rubber in Qingdao changed [10].

Report Industry Investment Rating - The mid - term outlook for the industry is "oscillation" [9] Report's Core View - The performance of furnace materials is differentiated, and the upward momentum of finished products is weak. Iron ore prices are strong due to the expected release of restocking demand, while coking coal and coke prices are weak. The fundamentals of finished products in the off - season have limited highlights, and the futures prices have limited upward momentum. If there are still positive releases from the macro and policy fronts later, the phased upward opportunities can still be concerned [3][4][8] Summary by Related Catalogs 1. Overall Industry Situation - The supply and demand of the industry are marginally weakening, in line with off - season characteristics. The price is expected to oscillate in the short term. If there are positive macro and policy factors, there may be phased upward opportunities [5][8] 2. Different Product Analysis 2.1 Iron Element Products - **Iron Ore**: Overseas mine shipments have increased, and the arrival volume has declined. The port inventory has slightly decreased. The daily average hot metal has recovered, but there is a seasonal weakening expectation. The short - term price is expected to oscillate strongly. For example, the port transaction volume is 60.6(-15.2) million tons, the swap main contract is 104.4(+0.01) US dollars/ton, and the PB powder is 795(+3) yuan/ton [13][14] - **Scrap Steel**: The supply and demand are both weak. The arrival volume is low, and the total daily consumption has slightly decreased. The inventory of steel enterprises has slightly increased. It is expected that the price will oscillate with the finished products. The average price of East China crushed scrap is 2147(+1) yuan/ton, and the screw - scrap price difference in East China is 996(+8) yuan/ton [15] 2.2 Carbon Element Products - **Coke**: The supply is stable, the demand is supported, and the inventory is low. The cost support has weakened, and the price is temporarily in a dilemma. The futures price is expected to oscillate with coking coal. The quasi - first - grade coke at Rizhao Port is quoted at 1490 yuan/ton (-30) [16] - **Coking Coal**: The supply is slowly recovering, the import is at a high level, and the demand has slowed down. The market sentiment has cooled down, and the price is expected to oscillate. The medium - sulfur main coking coal in Jiexiu is 1430 yuan/ton (0), and the Mongolian No. 5 clean coal in Wubulangkou Jinquan Industrial Park is 1378 yuan/ton (0) [17] 2.3 Alloy Products - **Manganese Silicon**: The cost support is strengthened, but the supply - demand is loose, and the upward pressure is large. It is expected to operate at a low level around the cost. The ex - factory price of Inner Mongolia 6517 is 5600 yuan/ton (0) [21] - **Silicon Iron**: The cost valuation is firm, but the supply - demand is loose, and the upward driving force is insufficient. It is expected to operate at a low level around the cost. The ex - factory price of Ningxia 72 silicon iron is 5150 yuan/ton (0) [22] 2.4 Glass and Soda Ash - **Glass**: The supply is disturbed, and the inventory is high. If there is no more cold - repair before the end of the year, the price is expected to oscillate weakly; otherwise, it will rise. The mainstream large - plate price in North China is 1090 yuan/ton (-10), and the national average price is 1114 yuan/ton (-7) [18] - **Soda Ash**: The cost has increased, but the supply - demand is in excess. The short - term price is expected to oscillate, and the long - term price center will decline. The delivered price of heavy - quality soda ash in Shahe is 1170 yuan/ton (-) [20] 3. Steel Products - The third - round and fifth - batch of central ecological and environmental protection inspections may affect steel production in North China. The spot market transactions are weak, the steel mill profits are poor, the production has decreased, the demand has declined, and the inventory is still high year - on - year. It is expected that the futures price will oscillate widely. For example, the price of Hangzhou rebar is 3180 (0) yuan/ton, and the price of Shanghai hot - rolled coil is 3260 (-30) yuan/ton [12] 4. Commodity Index - On November 18, 2025, the comprehensive index of CITIC Futures commodities decreased by 0.86% to 2234.87, the commodities 20 index decreased by 0.83% to 2534.70, and the industrial products index decreased by 0.88% to 2208.90.
