Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - Nickel prices are expected to oscillate within a narrow range. The support logic at the ore end is weakening, and the smelting logic restricts the price elasticity. The global refined nickel inventory is gradually increasing, which puts downward pressure on nickel prices. In the short term, it is difficult for nickel prices to drop significantly, but there is also an upper limit. The inventory at the ferronickel link has slightly decreased, which slightly boosts the upside space of nickel prices, but the increase is limited. The fundamentals lack obvious contradictions, and the price movement is mainly influenced by the macro - sentiment of the sector. There are also some uncertainties in the news, such as Indonesia's possible adjustment of the RKAB approval cycle and the APNI's proposal to re - evaluate the nickel ore HPM formula [1]. - In the stainless - steel market, the tug - of - war between bulls and bears is intensifying, and steel prices are expected to fluctuate. The bulls focus on the decline in high - level inventories and potential supply - side production cuts, while the bears are concerned about the actual supply - demand situation, such as the profit from warehousing and the still - high inventory levels. Overall, steel prices are likely to move in a volatile manner [2]. Summary According to Related Catalogs Nickel and Stainless - Steel Fundamentals - **Nickel fundamentals**: The support from the ore end has weakened, and the smelting logic restricts price fluctuations. The global refined nickel inventory is gradually rising, which suppresses nickel prices. In the short term, it's hard for nickel prices to fall sharply, but there is an upper ceiling. The inventory at the ferronickel link has slightly decreased, slightly boosting the upside potential of nickel prices, but the increase is limited. The news about Indonesia's possible adjustment of the RKAB approval cycle and the APNI's proposal to re - evaluate the nickel ore HPM formula adds uncertainties [1]. - **Stainless - steel fundamentals**: The bulls are concerned about the decline in high - level inventories and potential supply - side production cuts, such as the maintenance of a Shandong steel mill and the phased production cuts in Guangxi. The bears focus on the actual supply - demand situation, including the profit from warehousing and the still - high inventory levels. Overall, steel prices are expected to fluctuate [2]. Inventory Changes - China's refined nickel social inventory decreased by 536 tons to 38,578 tons, with warehouse receipt inventory down 573 tons to 21,374 tons, spot inventory up 437 tons to 12,014 tons, and bonded area inventory down 400 tons to 5,190 tons.

Report Industry Investment Rating No relevant content provided. Core Viewpoints - For PTA, although it remains in a state of inventory accumulation, the absolute inventory level is not high. With the current low processing fees for spot goods persisting for some time, and considering the limited inventory pressure of filament and the continuous inventory reduction of bottle - grade chips at low operation rates, the polyester operation rate is expected to gradually stabilize and has upward potential. It is advisable to look for opportunities to expand processing fees by buying at low prices [2]. - For MEG, the short - term inventory accumulation pressure is not significant, and the port inventory is expected to remain at a low level. The situation is favorable and the profit margin is decent. However, in the far - term, there is an expectation of inventory accumulation due to the restart of overseas plants and the further increase of coal - based operation rates. The valuation is greatly affected by the subsequent evolution of the cost side, and it should be regarded as a wide - range fluctuation. Attention should be paid to the restart progress of satellite plants [2]. - For polyester staple fiber, as the finished - product inventory of the polyester yarn end is reduced, the downstream operation rate may increase. Although the supply of staple fiber itself may also increase, considering that the processing fees on the futures market are still in a relatively low range, opportunities to expand processing fees by buying at low prices can be considered [2]. - For natural rubber and 20 - grade rubber, the national explicit inventory remains stable at a relatively low level but does not show seasonal reduction. The price of Thai cup - lump rubber has rebounded due to rainfall affecting rubber tapping. The strategy is to wait and see [2]. Summary by Related Catalogs PTA - **Price and Margin Changes**: From August 1 to August 7, crude oil prices dropped from $69.7 to $66.4, PTA internal - market spot prices decreased from 4750 to 4690, and PTA processing fees decreased from 121 to 101.

Report Industry Investment Rating No relevant content provided. Core Views - The long - term view on oil prices is bearish, with Brent expected to trade in the range of $66.5 - 68 per barrel in the short term. The overall supply - demand pressure for plastics and PP remains large, and their prices are expected to be weak and volatile. PVC and caustic soda also face supply - demand pressure, and short positions are recommended. For some products like fuel oil, a wait - and - see approach is advised, while for others, different trading strategies such as short - selling at high prices are proposed according to their supply - demand situations [2][22][24] Summary by Directory 1. Crude Oil - **Market Review**: WTI2509 contract closed at $64.35, down $0.81 per barrel (-1.24%); Brent2510 contract closed at $66.89, down $0.75 per barrel (-1.11%); SC main contract 2509 fell 4.9 to 504.2 yuan per barrel, and dropped 6.2 to 498 yuan per barrel in the night session. The Brent main - second line spread was $0.61 per barrel [1] - **Related News**: US - Russia negotiations are progressing, and there is uncertainty in geopolitical conflicts. Trump may meet with Putin next week, and the US plans to impose secondary sanctions on countries buying Russian oil. Trump also announced a 25% tariff on Indian goods and may impose further tariffs on China. Some Fed officials believe in interest rate cuts due to economic and labor market conditions. EIA data shows a decline in US crude and refined product inventories [1][2] - **Logic Analysis**: Long - term bearish view on oil prices due to increasing risk of US economic weakness and sufficient supply elasticity, with an expectation of future supply - demand surplus. Brent is expected to trade in the $66.5 - 68 per barrel range in the short term [2] - **Trading Strategy**: Unilateral: Weak and volatile; Arbitrage: Gasoline crack spread is weak, diesel crack spread is stable; Options: Wait - and - see [3] 2. Asphalt - **Market Review**: BU2510 closed at 3543 points (+0.40%) in the night session, BU2512 closed at 3448 points (+0.207%).

Group 1: Core View - The growth of US soybeans is in good condition, and the trade policies between the US and other countries show no obvious signs of easing, putting pressure on the US market, but the downside space is expected to be limited. The current trade situation between China and the US may keep the Brazilian premium strong. The domestic market presents a situation of weak reality and strong expectation, with the NO1 contract expected to fluctuate strongly, but the short - term strong performance of soybean oil suppresses the performance of soybean meal. Follow - up attention should be paid to whether the USDA August supply - demand report will raise the US soybean yield per unit and the domestic import situation of Argentine soybean meal [6][7] - In terms of supply, the good - rate of US soybeans has risen to 70% this week. Although the rainfall in the production areas will be slightly less in the next two weeks without obvious high - temperature, the expected impact is limited. Under the pressure of the concentrated arrival of Brazilian soybeans, the domestic soybean crushing in August is expected to exceed 10 million tons, and soybean meal is expected to continue to be abundant. The purchase of ships from October to January is progressing slowly, and there is an expectation of inventory reduction in the far - month under the current China - US trade policy [6] - In terms of demand, the breeding cycles of pigs and poultry are expected to maintain high inventory, supporting feed demand. However, the policy aims to control the inventory and weight of pigs, which is expected to affect the far - month pig supply. Soybean meal has a high cost - performance ratio, and the pick - up volume is at a high level. In some areas, wheat replaces corn, reducing the demand for protein. The trading volume of soybean meal has increased this week [7] - In terms of inventory, the domestic soybean inventory has increased to a high level; soybean meal has a small inventory reduction but is still in the inventory accumulation cycle; the inventory days of soybean meal in feed enterprises have decreased [7] Group 2: Data Summary Basis Data - The basis data of soybean meal and rapeseed meal in different regions and time periods are presented, including the basis of soybean meal main contract in Zhangjiagang on August 6, the basis of 43% soybean meal spot, the basis of rapeseed meal spot, etc. For example, the basis of soybean meal main contract in Zhangjiagang on August 6 is - 23 [5] Spread Data - The spread data include the M9 - 1, M9 - RM9, RM9 - 1 spreads, the spot spread and the main - contract spread of soybean meal - rapeseed meal. For example, the M9 - 1 spread is - 46, and the spot spread of soybean meal - rapeseed meal in Guangdong is 281 [6] Other Data - The data also involve the US dollar - RMB exchange rate, the soybean CNF premium, the import soybean gross profit, the inventory of soybeans in Chinese ports and major oil mills, the inventory days of soybean meal in feed enterprises, the inventory of soybean meal in major oil mills, the start - up rate and the soybean crushing volume of major oil mills [6]

Group 1: Report's Core View - The port accelerated inventory accumulation this week. Overseas methanol production remained at a high level, increasing the pressure of arrivals in August. The Xingxing MTO device in the port area started a one - month maintenance at the end of July. In the inland area, there will still be some maintenance in the northwest in August, and the production will not fully recover until late August. The traditional downstream demand showed certain resilience, and the inventory of inland methanol factories decreased further. Overall, the inland market was stronger than the port market [3] Group 2: Market Data Inland Market - Q5500 Ordos thermal coal was 470 yuan/ton (unchanged), and the production profit of coal - based methanol in Inner Mongolia was 695 yuan/ton (+25). The inland methanol prices varied by region: Inner Mongolia North Line was 2110 yuan/ton (+25), Inner Mongolia South Line was 2100 yuan/ton (unchanged), Shandong Linyi was 2383 yuan/ton (+10), Henan was 2250 yuan/ton (unchanged), and Hebei was 2275 yuan/ton (+25). The inland factory inventory was 293,688 tons (-30,832), and the northwest factory inventory was 185,500 tons (-30,500). The inland factory's pending orders were 240,800 tons (+10,075), and the northwest factory's pending orders were 122,800 tons (+10,800) [1] Port Market - The methanol price in Taicang was 2388 yuan/ton (+15), the basis was - 8 yuan/ton (+16), CFR China was 268 US dollars/ton (+1), and the import price difference in East China was 13 yuan/ton (-3).

Strategy - **Unilateral**: Cautiously bearish [6]. - **Arbitrage**: Neutral [6].

1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views Steel - The steel market shows signs of stabilizing. The recent decline in steel prices was mainly affected by the drop in coking coal prices. In the off - season, the supply and demand of steel are basically balanced, with a small increase in inventory. Steel prices rose in July, and inventory shifted from steel mills to traders. Steel mills have over - sold recently, and forward orders have been received for 20 - 30 days later. In the short term, steel inventory pressure is low, and as demand transitions from the off - season to the peak season, steel prices are expected to be supported. The main risk is the interference from the expected supply of coking coal. It is recommended to take a long - biased approach on price pullbacks and lightly test long positions at the current level [1]. Iron Ore - The iron ore 09 contract showed a volatile upward trend. Globally, the iron ore shipping volume decreased month - on - month, while the arrival volume at 45 ports increased. Based on recent shipping data, the average future arrival volume is expected to decline. On the demand side, steel mills' profit margins are at a relatively high level, with a slight increase in maintenance volume and a slight decline in molten iron production, which remains at around 240,000 tons per day. Currently, steel exports remain strong, and the short - term resilience of molten iron is maintained. Terminal demand shows a strong performance during the off - season but weakens month - on - month. In terms of inventory, port inventory decreased slightly, the shipping volume decreased month - on - month, and steel mills' equity ore inventory increased month - on - month. In the future, molten iron production in August will remain high, with an average expected to be around 236,000 tons per day. The improvement in steel mills' profits will support raw materials, and there is a seesaw effect between coking coal and iron ore. The Ministry of Industry and Information Technology plans to introduce a stable growth plan for ten key industries, and there are expectations of production restrictions for Hebei steel mills before the September 3rd parade, which may lead to an increase in steel prices and iron ore prices will follow. It is recommended to go long on dips for single - side trading and long iron ore and short steel for arbitrage [4]. Coke - The coking coal futures rebounded after hitting the bottom, with significant price fluctuations recently. The fifth round of coke price increase was officially implemented, and port trade quotes remained stable. On the supply side, coal mine复产 is below expectations, and although coking production restrictions have been lifted, production is difficult to increase due to some enterprises' losses. On the demand side, blast furnace molten iron production decreased slightly from a high level, and downstream demand provides support. It is expected that molten iron production will continue to decline slightly in August. In terms of inventory, coking plants' inventory continued to decrease, port inventory increased slightly, and steel mills' inventory decreased. The overall inventory is at a medium level. As steel mills increase inventory replenishment at low prices, it is beneficial for future coke price increases. There is room for hedging due to the premium of coke futures over the spot. In August, there are positive drivers from production restrictions in Shanxi and Hebei for coking and steel industries. There are expectations of a sixth - round price increase in the short term. It is recommended to go long on coke 2601 for speculation and conduct a 9 - 1 reverse spread for arbitrage, while being cautious of increased market volatility [5]. Coking Coal - The coking coal futures rebounded after hitting the bottom, with significant price fluctuations. The spot auction prices were stable with a slight upward trend, Mongolian coal quotes stabilized, and large - mine long - term contract prices increased. On the supply side, coal mine operations decreased month - on - month. Due to good sales, coal mines mainly held firm on prices, and the market remained in short supply. In terms of imported coal, Mongolian coal prices stabilized this week after following the futures decline last week, and downstream users continued to replenish inventory. On the demand side, coking operations remained stable, and downstream blast furnace molten iron production decreased slightly from a high level, with continuous downstream inventory replenishment demand. In August, molten iron production is expected to remain at around 236,000 tons per day. In terms of inventory, coal mines continued to rapidly reduce inventory, ports and borders also saw inventory reduction, and downstream actively replenished inventory, with the overall inventory at a medium level. Although the spot fundamentals are under pressure due to the futures market, there are still expectations of coal mine production restrictions in August. It is recommended to go long on coking coal 2601 for speculation and conduct a 9 - 1 reverse spread for arbitrage, while being cautious of increased market volatility [5]. 3.
