1. Report Industry Investment Ratings - No specific industry - wide investment ratings are provided in the report. 2. Core Views PTA - The PTA balance shows less - than - expected destocking month - on - month. It maintains a tight balance in September, with minor current supply - demand contradictions. Attention should be paid to the lower support [5][50]. PX - PX is in a tight - balance state for the polyester industry. There are few changes in maintenance, and the balance pressure is low. It should be operated with low - level oscillations, and its elasticity comes from PXN [6][72]. Ethylene Glycol - Ethylene glycol has a record - low port inventory, and it is difficult to accumulate inventory in the short term. The existing supply is high. With new device commissioning plans, the short - term outlook is cautiously bullish, and it should be treated as a low - buying opportunity during oscillations [7][107]. 3. Summaries by Related Catalogs Attention to the Peak Demand Season Expectation - Terminal orders have shown partial improvement, and the weaving operation rate has slightly increased. The operation rates of texturing, weaving, and dyeing are 79% (+7%), 68% (+5%), and 72% (+5%) respectively. Downstream raw material inventory is 10 - 20 days, and orders have slightly improved. The market anticipates a seasonal improvement in the peak season [9]. PTA Tight Balance - **Device Changes**: PTA device maintenance is less than expected. Hengli has one line under maintenance, and the other is undetermined. Dushan Energy is under maintenance, Fuhai Chuang's restart is postponed to mid - September, and new lines of Sanfangxiang are operating stably while the old line will stop after the new one stabilizes. YS Hainan and YS Dahua are under planned maintenance [43][50]. - **Inventory**: As of August 22, PTA social inventory remained stable, with a decrease of 8.3 tons to 212 tons (excluding credit warehouse receipts). The balance in September is tight [44]. - **Supply - Demand**: The PTA balance destocking is slightly less than expected. It maintains a tight balance from August to September. The supply side has device maintenance, and the demand side has stable polyester load and slightly improved weaving orders [50]. PX with Elasticity - **Supply**: The domestic PX load changes little, with a domestic load of 83.3% and an Asian load of 75.6%. Jinling Petrochemical slightly reduced its load, Fuhai Chuang will restart in early September, and Daxie plans to increase its load in September. Overseas, Idemitsu restarted, and Saudi Arabia slightly increased its load [72]. - **Balance**: The PX balance is acceptable, with PXN compressed to around $250 +. It should be operated with short - term oscillations [72]. EG Low Inventory and General Expectation - **Device Changes**: The overall domestic ethylene glycol load is 75%, and the coal - based load is 77%. Satellite's one - line maintenance is postponed to early October. Coal - chemical maintenance slightly increases in September. Overseas, Singapore's 900,000 - ton device's restart is postponed for several months [84][107]. - **Inventory**: As of September 1, the ethylene glycol port inventory in the East China main port area was about 44.9 tons, a month - on - month decrease of 5.1 tons, reaching a record low. The arrival volume is expected to be neutral in the short term, and the port inventory is expected to remain stable or slightly decrease [102]. - **Supply - Demand**: The ethylene glycol market has a strong reality of low inventory. The inventory is difficult to accumulate in the short term. The supply is high, and the demand has stable polyester load. It should be operated with short - term oscillations [107]. Spread Structure - No specific analysis of the spread structure is summarized in the report other than showing some price charts of different products such as PX, PTA, ethylene glycol, etc.

1. Report Industry Investment Rating - Core view: Neutral [3] - Month spread: Neutral [3] - Steel mill profit: Bearish [3] - Scrap steel: Neutral [3] - Finished product inventory: Neutral [3] 2. Core View of the Report - Last week, the market fluctuated downward. Hot metal production decreased slightly but remained in positive year-on-year growth. It is expected that hot metal production will decline significantly next week. Last week, rebar production increased significantly, inventory accumulated substantially, and apparent demand recovered. Hot-rolled coil production decreased slightly, inventory accumulated marginally, and apparent demand declined. The total output of five finished steel products increased slightly week-on-week, inventory accumulated overall, and demand recovered slightly. In terms of valuation, the profits of long-process steel mills continued to narrow, and short-process steel mills had a slight loss during off-peak hours. The eighth round of coke price increase failed, and the market reported expectations of a price cut in the future. Attention should be paid to the subsequent changes in hot metal production and the recovery of exports. The month spread structure is in contango, showing a continuous reverse spread trend. The market reported that there will be significant pressure on rebar warehouse receipts in the future, and attention should be paid to the delivery situation. This week, the profitability rate of 247 steel enterprises was 63.64%, continuing to decline slightly week-on-week. According to calculations, the current loss per ton of steel produced by electric arc furnaces in East China is 158 yuan/ton during peak hours and 30 yuan/ton during off-peak hours. The inventory of five finished steel products is accumulating, and the overall inventory is still at a low level. The billet inventory is accumulating. Attention should be paid to the subsequent changes in overall inventory [3]. 3. Summary by Relevant Catalog Market Review - As of August 29, 2025, the average daily pig iron output was 2.4013 million tons, a slight decrease of 0.62 million tons week-on-week, and continued positive year-on-year growth.

Report Summary 1. Industry Investment Rating No specific industry investment rating is provided in the report. 2. Core Viewpoints - **Short - term**: RU is neutral - biased long, NR is neutral. As of August 29, RU and NR prices rose, the RU - NR spread widened, and the RU09 - 01 spread widened. RU's recent frequent rainfall in production areas hindered tapping, leading to tight raw material supply and strong glue prices, with a slight reduction in light - colored rubber inventory. NR was affected by typhoons in Vietnam, with slow supply increase in overseas main production areas, stronger Thai cup - lump prices, and a slight reduction in dark - colored rubber inventory. However, tire开工率 declined, semi - steel tire inventory digestion was slow, and tire exports over - drafted subsequent demand, and domestic demand awaited verification during the "Golden September and Silver October" peak season. It is judged that RU prices will fluctuate widely this week, and NR prices will fluctuate with a slight upward trend [4]. - **Medium - to long - term**: RU is neutral - biased short, NR is neutral - biased short. The factors affecting long - term trends are similar to short - term ones, mainly considering the supply - demand relationship in the tire market and the impact of weather on rubber production [4]. 3. Summary by Related Catalogs **Market Data** - **Prices**: As of August 29, Thai cup - lump price was 50.5 Thai baht/kg, up 1 Thai baht/kg from last week; Thai glue price was 55.45 Thai baht/kg, up 0.45 Thai baht/kg from last week. Shanghai state - owned whole milk price was 14,900 yuan/ton, up 250 yuan/ton from last week; Shanghai Vietnam 3L price was 15,100 yuan/ton, up 300 yuan/ton from last week; Shanghai RSS3 price was 19,900 yuan/ton, up 200 yuan/ton from last week. International prices: Thai standard price was 1,850 US dollars/ton, up 40 US dollars/ton from last week; Indian standard price was 1,730 US dollars/ton, up 20 US dollars/ton from last week; Thai mixed price was 1,840 US dollars/ton, up 40 US dollars/ton from last week; Malaysian mixed price was 1,830 US dollars/ton, up 40 US dollars/ton from last week [21][71][82]. - **Spreads**: As of August 29, the RU - NR spread was 3,165 yuan/ton, up 50 yuan/ton from last week, and it is expected to continue widening. The Thai mixed spot - RU main contract spread was - 1,060 yuan/ton, down 35 yuan/ton from last week. The Thai standard spot - NR main contract spread was 409.7 yuan/ton, up 11.5 yuan/ton from last week; the Thai mixed spot - NR main contract spread was 454.65 yuan/ton, down 9.05 yuan/ton from last week. The RU09 - 01 spread was - 975 yuan/ton, down 20 yuan/ton from last week; the RU01 - 05 spread was - 80 yuan/ton, up 20 yuan/ton from last week; the NR consecutive one - consecutive two spread was - 30 yuan/ton, down 5 yuan/ton from last week; the NR consecutive two - consecutive three spread was - 30 yuan/ton, up 20 yuan/ton from last week [4][94][109]. **Supply - related** - **Production Areas Weather**: During the period from August 26 to September 2, Vietnam was affected by typhoons "Jianyu" and "Lanhu". The estimated rubber production loss due to heavy rainfall was about 0.29 - 0.48 tons, which will be released after the weather improves. Yunnan's rainfall gradually subsided, while Hainan was more significantly affected by typhoon "Lanhu", with expected increased rainfall that would hinder tapping [10][31]. - **Thai Supply**: Thai weather was normal, raw material prices increased marginally, and production was stable. The Thai Rubber Authority (RAOT) launched a plan to export rubber to China via the Mekong River with zero import tax, aiming to increase prices. The first batch of 400 tons of cup - shaped rubber will be shipped in September this year, and commercial shipments are planned to start in October 2025, with production increasing to 2,400 tons [4][21]. - **Ivory Coast Exports**: In July 2025, Ivory Coast exported 2.85 tons of natural rubber to China, a decrease of 0.55 tons from the previous month, a month - on - month decrease of 16.29% and a year - on - year increase of 92.59%. From January to July 2025, Ivory Coast's total exports of natural rubber to China were 27.84 tons, a decrease of 9.61 tons compared to the same period, with a total year - on - year increase of 52.73% [26]. **Demand - related** - **Tire Industry**: As of August 29, the semi - steel tire开工率 was 72.77%, down 0.36% from last week.

Due to anti - dumping measures in the EU, there was a rush to export, over - drafting subsequent orders, and downstream tire factories were pessimistic, making short - term inventory digestion difficult. As of August 28, the whole - steel tire开工率 was 63.84%, down 0.92% from last week. In July 2025, the export volume of Chinese whole - steel tires was 45.44 tons, a decrease of 4.72 tons from the previous month, a month - on - month increase of 11.6% and a year - on - year increase of 13%. Enterprises' exports remained active, domestic sales were stable, and it is expected that the开工率 will improve in September [55][61]. - **Inventory**: As of August 24, the total social inventory of light - colored rubber was 47.3 tons, a month - on - month decrease of 1.25%; the total social inventory of dark - colored rubber was 79.7 tons, a month - on - month decrease of 1.12%. As of August 29, the combined inventory of bonded and general trade of natural rubber in Qingdao was 60.23 tons, a decrease of 0.4 tons from the previous period, a decrease of 0.6%. The bonded area inventory was 7.32 tons, a decrease of 0.14%; the general trade inventory was 52.91 tons, a decrease of 0.7%. It is expected that the inventory in Qingdao Port will continue to decline slightly in the next period [4][48][94].

From August 25 - 31, the expected arrival is about 5.4 tons, and the port is expected to slightly reduce inventory in the short term. Polyester factories' ethylene glycol raw material inventory days are 12 days [96] - Ethylene glycol has a strong current situation but weak expectations. The near - end low inventory has little pressure to accumulate, the coal - based load is at a high level. It is expected that existing devices will restart and new ones will be put into production in the fourth quarter. There is support from anti - involution and coal. Pay attention to reverse - spread opportunities [101]

1. Report Industry Investment Rating - The report gives a neutral rating for the industry [4] 2. Core Viewpoints - Market rumors of domestic procurement of Australian rapeseed have been confirmed with cumulative deals of 5 cargoes, which can make up for the shortage of rapeseed arrivals in the fourth quarter [4] - With increasing far - month exports of domestic soybean oil, downstream buyers are actively purchasing the basis of soybean oil from October to January, but be wary of reserve soybeans and Sino - US negotiations [6] - As India's peak procurement season is approaching its end, the bullish drivers for palm oil will be more on the supply side. However, even with supply - side drivers, the upside of the futures market may be limited, and there could be downward pressure if inventory accumulation exceeds expectations [6] 3. Summary by Related Catalogs Palm Oil Market - In the GAPKI June report, palm oil production in Indonesia increased by 15.99% month - on - month. In early July, the market expected a production cut in June. Due to tax cuts in June, exports increased by 35.56% month - on - month. With lower biodiesel subsidy costs and high consumption, the inventory at the end of August dropped to 253 million tons, a historical low. Most expect July production to be flat or slightly lower, and inventory accumulation at the end of July may be limited [4] - MPOA estimates that Malaysia's palm oil production in the first 20 days of August increased by 3.03%, lower than the historical average. However, according to shipping inspection agency data, export growth is slowing down, and inventory may continue to accumulate at the end of August unless consumption continues to exceed expectations [4] - After 8 cargoes of palm oil were traded in China last week, the origin's quotes weakened this week, and the import loss for the domestic futures market narrowed. Cargoes for the November shipment continued to be traded [5] - India's procurement of Malaysian and Indonesian palm oil has slowed down due to the narrowing of the soybean - palm oil price spread at Indian ports and news of India's procurement of South American palm oil [5] Price Movements - As of August 22, 2025, French rapeseed had the largest weekly increase, while price adjustments of rapeseed and soybeans in most regions were small [8] - As of August 25, 2025, except for a slight decline in the prices of Malaysian and Indonesian palm oil, other vegetable oil prices rose, especially the prices of North and South American soybean oil [13] - The weekly price difference between refined palm oil in Malaysia and Indonesia was $10/ton, compared to $0/ton the previous week, lower than the historical average of $11.7/ton.

Without Chinese purchases, it has to find other markets [24] - As of August 22, the price difference between crude soybean oil and crude palm oil at Indian ports was $30/ton, higher than $15/ton the previous week; the price difference between crude sunflower oil and crude palm oil was $115/ton, compared to $95/ton the previous week; the price difference between refined soybean oil and refined palm oil was $0/ton, compared to - $6/ton the previous week [30] Transaction Volume - Last week, 8 cargoes of palm oil for the October shipment, 2 for the September shipment, 1 for the October shipment, and 5 for the November shipment were traded. One cargo of Dubai rapeseed oil was also traded in China last week [39] - The far - month basis of soybean oil had a large number of transactions again [132] Basis and Spread - The spot basis of 24 - degree palm oil in Guangdong weakened again, the spot basis of first - grade soybean oil in Jiangsu was raised, and the basis of third - grade rapeseed oil in Guangxi remained stable [136] - On August 25, 2025, the spot price difference between first - grade soybean oil and 24 - degree palm oil in Guangdong was - $900.0; the spot price difference between third - grade rapeseed oil and first - grade soybean oil in Jiangsu was $1320; and the spot price difference between third - grade rapeseed oil and first - grade soybean oil was $1540 [148] Bio - diesel - Weekly processing profit and loss remained stable, subsidies decreased, and blending losses increased [127] - The price of European RME was stable, and the processing profit was at the historical average level [128] Demand - The far - month basis of soybean oil had a large number of transactions again [132] Monthly Balance Sheet - The monthly balance sheets for palm oil, rapeseed oil, and soybean oil show the changes in inventory, production, import, demand, and other indicators from 2024 to 2025 [155]

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The nickel market is expected to oscillate. Although refined nickel imports exceeded expectations last month, part of the inventory became hidden, causing no significant impact on domestic supply. The nickel ore price is relatively firm, with no further downward drivers in the future. Despite the expectation of peak - season stockpiling in September, which may support the demand for primary nickel, the supply side remains at a high level, and the fundamentals are unlikely to improve significantly. Attention should be paid to changes in macro - expectations [3][4]. - The stainless - steel market is currently in a situation of weak supply and demand. Weak demand dominates short - term price adjustments, while the peak - season expectations of "Golden September and Silver October" may provide bottom support for prices [4]. 3.

Report Industry Investment Rating - The overall investment rating for the pure benzene and styrene industry is neutral [3] Core Viewpoints - Pure benzene: Last week, the operating load of pure benzene increased, with no new maintenance capacity and the restart of multiple maintenance devices, leading to a continuous increase in overall supply. With maintenance mostly completed, supply is expected to remain stable in September, still at a relatively high level. In terms of imports, South Korea's exports to China in the first ten days of August decreased significantly month-on-month, and China's imports in August are expected to decline substantially. Downstream demand is at a relatively high level for the same period, but overall downstream profits have declined significantly. In the short term, supply and demand for pure benzene are expected to be strong, but in the long run, poor downstream profits may lead to weakening demand. Particular attention should be paid to the stability of styrene demand. Port inventory of pure benzene has increased, and subsequent destocking is expected, with an upward driving force. In terms of valuation, the BZN spread is neutral, and the valuation is also relatively neutral [3] - Styrene: Last week, Fushun Petrochemical carried out maintenance on its styrene unit. Supply is expected to be high in August but may tighten in September due to an increase in maintenance. In terms of demand, multiple PS units increased their loads, and EPS had good sales at low prices, alleviating some inventory pressure. Overall, the comprehensive operating rate of the three downstream S products has rebounded, but current demand remains weak, mainly driven by rigid needs, and raw material inventories are high. In terms of terminal inventory, port inventory remained stable last week, and there is still pressure to accumulate inventory in August, with a downward driving force. In terms of valuation, the BZ - SM spread has declined significantly, and the styrene valuation is neutral [3] Summary by Relevant Catalogs Pure Benzene Supply - There are no new maintenance plans for pure benzene units, and the current operating rate is at a high level. Supply is expected to continue increasing [3] - Last week, there were no new maintenance devices for pure benzene, and supply is expected to increase. The maintenance of hydrogenated benzene is basically over, and supply is expected to remain at a high level [7][10] - After the peak of pure benzene maintenance has passed, with the commissioning of new devices, supply in August is expected to increase month-on-month [47] Pure Benzene Demand - Downstream overall operating rates are high and are expected to remain stable in the short term. However, downstream profit margins are poor, limiting demand potential. As the "Golden September and Silver October" period approaches, the situation of end - users should be observed [3] Pure Benzene Month - Spread - Pure benzene is expected to undergo destocking, and the paper futures month - spread structure is close to flat [3] Styrene Supply - Current supply is high, but may contract in September due to an increase in maintenance [3] - Last week, the styrene operating rate increased. Although Fushun Petrochemical's unit was under maintenance, overall supply remains high. Maintenance will increase in September, and supply may tighten [52] - With the commissioning of new devices, styrene supply is expected to continue to rise [87] Styrene Demand - The operating rate of the three downstream S products remains stable but is weak. Overall downstream profits are good, and demand is expected to remain stable [3] - Currently, the three S products are in the off - season. Overall demand shows some resilience, but inventories of the three S products are high, and subsequent demand may weaken. Attention should be paid to the destocking situation of the three S products during the "Golden September and Silver October" period [87] Styrene Month - Spread - Given the pattern of strong supply and weak demand combined with improved long - term expectations, the C structure is expected to be maintained [3] External Market Support - The arbitrage window between the US and Asia remains closed. In the first ten days of August, China imported 38,725 tons of pure benzene from South Korea, a significant month - on - month decrease and lower than the same period last year [3]
