Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - The fundamentals still support copper prices, and Shanghai copper is expected to maintain a volatile pattern before the holiday [1]. - Aluminum prices are expected to fluctuate in the short - term due to factors such as inventory changes and export incentives [2]. - Nickel is expected to oscillate weakly in the medium - to - long term due to supply surplus, although cost support limits the downside [3][4]. - Tin prices are expected to have greater volatility, and range trading is recommended, with attention to supply and demand changes [5]. Summary by Related Catalogs 1. Basic Metals Copper - As of May 26, the Shanghai copper main 06 contract rose 0.57% to 78,270 yuan/ton. Macro disturbances are weakening, but Sino - US trade uncertainties remain. Mine - end disruptions continue, and the cost pressure of smelters limits price decline. Consumption in May weakened compared to April but is better than the same period. Social inventory is at a low level, and there may be some restocking sentiment before the Dragon Boat Festival [1]. Aluminum - As of May 26, the Shanghai aluminum main 07 contract fell 0.05% to 20,155 yuan/ton. The revocation of mining licenses in Guinea has escalated. Alumina operating capacity is expected to gradually recover, and electrolytic aluminum operating capacity is increasing. The downstream开工率 is declining, but aluminum inventory has been unexpectedly depleted, and short - term aluminum prices are expected to fluctuate [2]. Nickel - As of May 26, the Shanghai nickel main 06 contract fell 0.08% to 122,780 yuan/ton. The nickel ore market in Indonesia is tight, and the downstream nickel - iron industry has losses. The pure nickel is in surplus, and stainless steel demand is average. The cost of nickel is firm, but there is a long - term supply surplus, and prices are expected to oscillate weakly [3][4]. Tin - As of May 26, the Shanghai tin main 06 contract fell 0.24% to 264,050 yuan/ton. Supply has recovered, and prices are oscillating. Production and imports have increased, and the semiconductor industry is showing signs of recovery. The supply of tin ore is tight, but there are strong expectations of mine - end resumption. Prices are expected to fluctuate more, and range trading is recommended [5]. 2. Spot Transaction Summary Copper - Domestic spot copper prices rose. Due to limited restocking demand before the Dragon Boat Festival, downstream procurement was cautious, and only low - priced goods were purchased, with a slight increase in premiums [6]. Aluminum - The spot aluminum market was stable with a slight upward trend. Tight arrivals and inventory depletion supported sellers' price - holding sentiment, but some sellers increased shipments, and overall trading remained active [7]. Other Metals - For zinc, the spot market trading was mediocre, with high premiums due to pre - holiday restocking. For lead, the spot market trading was light. For nickel, the spot market trading was light due to the weekly effect. For tin, the spot market trading was average, and merchants were mainly in a wait - and - see mode [9][11][12][13]. 3. Warehouse Receipt and Inventory Report - SHFE copper, aluminum, nickel, and tin futures warehouse receipts decreased, while lead futures warehouse receipts increased, and zinc futures warehouse receipts remained unchanged. LME copper, lead, zinc, aluminum, and nickel inventories decreased, and tin inventory remained unchanged [15].

Report Industry Investment Rating No relevant content provided. Core Viewpoints - The expected increase in production by OPEC+ has led to a decline in crude oil prices, dragging down the center of gravity of the aromatic hydrocarbon system from the valuation side. The recent rebound of styrene was mainly driven by tariff relaxation and the strengthening of spot goods under low inventory. However, this week, the spot market has shown some weakness, with prices starting to fall. Fundamentally, the high inventory of styrene's downstream 3S products may indicate an unsmooth transmission to the end - market. Coupled with ongoing profit challenges and the lack of a significant increase in orders during the export rush, there is a negative feedback expectation for high - priced styrene in the future. Additionally, the supply - demand situation of pure benzene, a raw material, has not improved significantly. With the return of domestic maintenance and increased supply from South Korea, there is significant pressure to reduce inventory, and the price center of pure benzene may decline. Therefore, styrene is expected to be bearish in the medium term, and attention should be paid to the resistance above 7800 - 7900 for the near - term contract. In terms of arbitrage, opportunities for the widening of the EB - BZ spread can be explored [4]. Summary by Related Catalogs Pure Benzene - **2025 Production Plan**: Multiple companies in different provinces have plans to put new capacity into production for pure benzene, its downstream products (excluding styrene), styrene, and styrene downstream products in 2025. For example, Yulong Petrochemical in Shandong plans to add 100 tons of pure benzene production capacity from 2024Q4 - 2025 using multiple processes [7]. - **May - July 2025 Device Dynamics**: Many companies' pure benzene - related devices have planned maintenance or production stops during May - July 2025. As of now, it is estimated that the planned new capacity for pure benzene from May - July is 1.33 million tons/year, with about 400,000 tons/year of new downstream capacity. The planned shutdown of pure benzene involves 4.46 million tons/year of capacity, and the downstream shutdown capacity is about 5.89 million tons/year. Overall, the net supply of pure benzene will decrease by about 239,000 tons, and the net demand will decrease by about 341,000 tons, resulting in inventory accumulation [9][10]. - **Catalytic Cracking and Related Spreads**: The toluene disproportionation profit is relatively low, and various spreads such as the ethylene - naphtha spread, pure benzene - naphtha spread, etc., show different trends over time [16]. - **Price and Supply - Demand**: The price of pure benzene in East China and its international quotes show different trends. South Korea's exports of pure benzene to China have remained at a high level. Although there are more maintenance activities, high production and imports have led to inventory accumulation. The weighted operating rate of pure benzene's downstream has recently declined slightly, and except for styrene, the profits of other downstream products are still weak [21][27][32]. Styrene and Its Downstream - **Styrene Futures and Spot**: The styrene spot price and its basis, monthly spreads, and registered warehouse receipts show different trends over time [54]. - **Styrene Supply**: Styrene's monthly and weekly production, operating rate, non - integrated and integrated profits, and the styrene - pure benzene spread are presented. China is gradually changing from a net importer of styrene to a net exporter, and it has maintained export performance from April - May [59][71]. - **Styrene Inventory**: The port inventory of styrene is at a relatively low level compared to the same period last year, while the factory inventory is accelerating inventory reduction but is still high compared to the same period [72]. - **Styrene Downstream**: The 3S products (PS, EPS, ABS) have high production capacity growth rates, which have intensified industry competition. As of May 22, the capacity utilization rates of EPS, PS, and ABS have changed. The estimated weekly consumption of styrene converted from 3S production has slightly decreased. The prices of 3S products have weakened, and their profits are under pressure. High production has led to relatively high inventory, indicating resistance in demand transmission. In the terminal market, exports are likely to be restricted after the implementation of tariffs, and domestic demand depends on subsidy incentives [77][80][90].

Report Industry Investment Rating No relevant content provided. Core Viewpoints - The overseas risk appetite has decreased, and attention should be paid to the impact of economic data releases on market sentiment. There is still a need to be aware of the long - term economic decline risk under US tariff policies. The copper raw material supply remains in a tight pattern, with strong price support, but the price center is expected to move down due to reduced consumption intensity [1]. - The domestic commodity sentiment is marginally stable, while the overseas risk appetite has weakened. High tariff levels lead to concerns about long - term demand. The high processing fees of aluminum rods are conducive to further inventory reduction of aluminum ingots, with strong price support, but the seasonal weak consumption will limit the upward space of aluminum prices, and the short - term price is expected to be volatile [3]. - The inventory of recycled raw materials is limited, and the profit of recycled lead enterprises is under pressure, with the operating rate continuously declining. After the battery enterprises' holidays, the operating rate has returned to a relatively high level. In the medium term, the Shanghai lead index is expected to fluctuate within a range of 16300 - 17800, and the short - term lead price shows a strong upward trend [5]. - In April, China's exports of unforged zinc alloys increased significantly. From a fundamental perspective, the port inventory of zinc concentrates continues to rise, and the processing fees of zinc concentrates increase again. The zinc ore surplus expectation remains unchanged. With the accumulation of zinc ingot inventory, the zinc price still has a certain downward risk in the medium term [7]. - The supply of tin is currently tight in the short term but is expected to loosen. The terminal orders in industries such as home appliances and electronics have not significantly increased, and the tin price center may move down under the drag of demand [8][9]. - The cost of nickel is expected to loosen, and the spot demand is weak. The inventory may return to the accumulation trend, and the nickel price maintains a bearish outlook [10]. - The supply and demand side of lithium carbonate lacks strong driving forces, and the futures price is in the cost - intensive area. If the demand does not weaken further, there is significant resistance to downward movement, and it is likely to fluctuate at the bottom [12]. - There are continuous disturbances in the ore and supply sides of alumina. The short - term impact of the mine shutdown in Guinea is large, and local policy uncertainty is high. It is recommended to wait and see in the short term [15]. - The nickel - iron market is in a game situation, and the high - carbon ferrochrome market is waiting for the June tender of steel mills. The stainless - steel market is expected to maintain a weak and volatile pattern in the short term [17].

In April, China's exports of unforged zinc alloys increased significantly. The zinc price still has a downward risk in the medium term [7]. Tin - On May 21, 2025, the Shanghai tin main contract closed at 267730 yuan/ton, up 1.13%. The domestic Shanghai Futures Exchange registered warehouse receipts increased by 45 tons to 8070 tons, and the LME inventory increased by 15 tons to 2670 tons. The upstream tin concentrate price rose. The tin ore supply is expected to loosen, and the tin price center may move down. The expected operating range of the domestic main contract is 250000 - 270000 yuan/ton, and that of overseas LME tin is 30000 - 33000 dollars/ton [8][9].

1. Report Industry Investment Ratings No relevant information provided. 2. Core Views - Soybean oil 2509 contract may fluctuate within a range in the short - term [1] - Soybean meal may oscillate with a slight upward trend in the short - term [1] - Corn futures prices may oscillate weakly in the short - term, and mid - term investors should watch for band - buying opportunities [1][2] - Copper prices have not completely shaken off the influence of moving averages, with the upper limit of the moving average system as the overall defense line [3] - The lithium carbonate 2507 contract may oscillate weakly, and investors can short at high prices [5][6] - For black commodities, negative feedback is gradually reflected in the market, and investors can take a long position at low levels [7] - Coking coal and coke may oscillate weakly at low levels due to ample supply [8] - Iron ore 2509 may oscillate in the short - term, and traders are advised to be cautious [9] - WTI crude oil may oscillate between $55 and $65 per barrel [10] - Rubber may oscillate, with an overall supply exceeding demand [11][12] - PVC futures prices may oscillate at low levels due to weak fundamentals [13][14] - Soda ash futures may continue to oscillate widely in the short - term [15] 3. Summary by Related Catalogs 3.1 Soybean Oil - **Spot Market**: The price of first - grade soybean oil in Zhangjiagang Yijiang is 8310 yuan/ton, unchanged from the previous trading day [1] - **International Soybeans**: In the current time frame, it is the season for US soybean sowing and growth and South American soybean harvesting and export. Brazil's soybean harvest is almost complete, and the new South American soybean crop is likely to be a bumper harvest. The USDA May 2025 report shows that the estimated soybean yield per acre in the 2025/26 season is 52.5 bushels, compared to 50.7 bushels in the 2024/25 season [1] - **Domestic Industry**: The medium - term de - stocking cycle of soybean oil may be ending. After the arrival of imported South American soybeans and customs clearance, soybean oil inventory may rebound from a low level [1] 3.2 Soybean Meal - **Spot Information**: The spot prices of 43% soybean meal in Zhangjiagang, Tianjin, and Dongguan are 2830 yuan/ton (- 20), 2930 yuan/ton (- 10), and 2890 yuan/ton (+ 20) respectively [1] - **Market Analysis**: Macroscopically, China and the US have reached a phased trade agreement, but long - term contradictions remain. Internationally, US soybean prices have risen due to weather speculation caused by rainfall in the producing areas. Domestically, soybean supply is gradually recovering, oil mill operating rates are increasing, and the supply of soybean meal is expected to shift from tight to loose. As downstream enterprises build safety stocks, they will switch to a just - in - time procurement and rolling replenishment model. Oil mill soybean inventories have risen to a high level, and the speed of soybean meal inventory accumulation is slow in the short term [1] 3.3 Corn - **Spot Information**: The average purchase price of new corn in key deep - processing enterprises in the three northeastern provinces and Inner Mongolia is 2195 yuan/ton; in key enterprises in North China and the Huanghuai region, it is 2414 yuan/ton. The purchase prices in Jinzhou Port (15% moisture/content 680 - 720) and Bayuquan (content 680 - 730/15% moisture) are 2260 - 2270 yuan/ton [1] - **Market Analysis**: Externally, the China - US joint statement on tariff reduction has led to expectations of looser long - term corn imports, which affects short - term prices emotionally but has limited negative impact on domestic futures prices. The May USDA report has raised US corn production and ending stocks, which is negative for US corn futures. Domestically, as the weather warms and the planting season approaches, the remaining grain in the producing areas has basically been sold. The north - south ports have started the de - stocking process, reducing short - term supply pressure. Downstream demand is weak, with cautious purchasing by downstream enterprises, low breeding profits leading to on - demand procurement by breeding enterprises, and low operating rates of corn deep - processing enterprises due to losses. Under the influence of the easing of China - US relations and the news of policy grain release, futures prices have declined periodically [1][2] 3.4 Copper - **Spot Information**: The price of Shanghai 1 electrolytic copper is 78290 - 78630 yuan/ton, up 230 yuan/ton, with a premium of 200 - 350 yuan/ton. The imported copper ore index is - 43.05, up 0.06 [3] - **Market Analysis**: Globally, the gradual easing of tariff confrontations is conducive to a positive outlook for the commodity market, in line with the international background and the possible end of the interest - rate cut cycle in 2025. Domestically, continuous policy support from the central bank, the CSRC, and the finance department has boosted market sentiment. However, raw material shocks are intensifying, and the mining problem has not been completely resolved. With the rapid decline of domestic copper inventories, the game between reality and expectation, as well as between the domestic and foreign markets, has intensified, complicating market analysis [3] 3.5 Lithium Carbonate - **Spot Information**: The market price of battery - grade lithium carbonate (99.5%) is 63000 yuan/ton (- 300), and that of industrial - grade lithium carbonate (99.2%) is 60850 yuan/ton (- 450). The price difference between battery - grade and industrial - grade lithium carbonate is 2150 yuan/ton (+ 100) [4] - **Market Analysis**: Fundamentally, the prices of various ores in the cost side have dropped significantly. Although the production cost of lithium carbonate has decreased, the profit margin has not expanded due to the rapid decline in lithium salt prices. In terms of supply, the weekly operating rate of the lithium carbonate industry has slightly decreased, but the overall output remains high. As the temperature rises, the production capacity of salt - lake lithium extraction will further increase, and the supply of low - cost lithium salt will increase, potentially suppressing market prices. In terms of demand, the production of cathode materials is stable, and the power battery market is growing steadily. The terminal consumer market has potential due to the launch of new technology models and policy incentives, but it is not strong enough to drive prices up. In terms of inventory, the weekly inventory has continued to accumulate. As of May 16, the weekly inventory is 131920 (+ 351) physical tons, including 56522 (+ 1670) physical tons in smelters, 41428 (- 728) physical tons in downstream enterprises, and 33970 (- 591) physical tons in other sectors. The monthly inventory in April is 96202 physical tons, a year - on - year increase of 51% and a month - on - month increase of 7%, with downstream inventory at 45169 (+ 5876) physical tons and smelter inventory at 51033 (+ 256) physical tons. Overall, due to the weakening cost support and macro - disturbances, both spot and futures prices have declined, and the subsequent focus is on the 60,000 yuan/ton integer support level [5] 3.6 Steel - **Spot Information**: The price of Shanghai rebar is 3170 yuan/ton, the operating rate in Tangshan is 83.56%, the social inventory of rebar is 532.76 million tons, and the inventory in rebar steel mills is 200.4 million tons [7] - **Market Analysis**: The fundamentals of the steel industry are gradually improving, with a weaker near - term and stronger long - term outlook, and the contango structure has weakened. The current valuation of steel is moderately low. In terms of cost and inventory, policy support for the real estate industry is helping it to stabilize. The apparent demand for steel has decreased year - on - year, and raw material prices have oscillated weakly this week. The cost center of steel is dynamically changing. Both social and steel mill inventories of steel are decreasing, and the overall inventory level is low. In the short term, macro - policy expectations dominate the market, and the fundamentals are also improving, showing a situation of strong supply and demand. Attention should be paid to the switching rhythm between macro - policy expectations and fundamental data [7] 3.7 Coking Coal and Coke - **Spot Information**: The price of main coking coal (clean coal, Mongolia 5) is 1205 yuan/ton; the price of metallurgical coke (quasi - first - grade) at Rizhao Port is 1340 yuan/ton; the inventory of imported coking coal at ports is 337.38 million tons; and the inventory of coke at ports is 246.10 million tons [8] - **Market Analysis**: In terms of supply, domestic production capacity is steadily recovering, and the capacity utilization rate of coking plants is stable. Although there are some disturbances in Mongolian coal imports, the overall volume remains high. In terms of demand, steel mills are reducing production, and there is an expectation of a decline in hot metal production, resulting in weak overall demand. In terms of inventory, independent coking enterprises maintain a low - inventory strategy for raw materials, and the overall inventory is slightly increasing. In terms of profit, the average profit per ton of coke is stable and approaching the break - even point [8] 3.8 Iron Ore - **Spot Information**: The Platts iron ore index is 100.1, the price of Qingdao PB (61.5%) powder is 763 yuan/ton, and the price of Australian iron ore powder (62% Fe) is 765 yuan/ton [9] - **Market Analysis**: The iron ore market is currently influenced by both positive and negative factors. On the supply side, Australian shipments have decreased after the end of the quarterly rush, while Brazilian shipments have continued to increase, and the global total shipments have slightly decreased. The port inventory has decreased by 112.39 million tons to 1.48 billion tons, indicating a short - term reduction in arrival pressure. On the demand side, the domestic steel mill's hot metal production has increased to 240.22 million tons per day, and the resumption of blast furnaces has led to a 2.46 - million - ton increase in the daily consumption of imported ore. However, steel mills are still cautious in raw material procurement and mainly replenish inventory as needed. Overseas demand is divided, with increased production in Indian steel mills supporting some demand, but the substitution effect of Southeast Asian electric arc furnaces is strengthening, reducing the dependence on iron ore. In addition, the repeated adjustment of US tariff policies has intensified the volatility of global commodity prices, and market concerns about the trade war have limited the upward space for iron ore prices [9] 3.9 Crude Oil - **Market Analysis**: The resurgence of波折 in the US - Iran negotiations has reduced the expectation of increased supply, supporting oil prices. However, the downgrade of the US sovereign credit rating by institutions has led to continued oscillation in crude oil prices. In the medium - to - long - term, the upside of oil prices is restricted. In terms of supply and demand, OPEC+ will increase production by 411,000 barrels per day in June, and the market expects an oversupply. In the long - term, the price center of crude oil will shift downward, but the WTI main contract has technical support at $55 per barrel and may oscillate around this level. OPEC has significantly lowered the global demand growth rate for the next two years. The escalation of the US trade war and the unpredictable policies of the Trump administration have raised concerns about global demand. The repeated delays in the Russia - Ukraine peace talks and the resurgence of波折 in the US - Iran negotiations have increased uncertainty [10] 3.10 Rubber - **Market Analysis**: Attention should be paid to overseas orders and domestic demand. The limited improvement in the fundamentals and the repeated situation after the positive news of the easing of the China - US trade war have restricted the rebound of rubber prices, which are mainly in a weak oscillation. Fundamentally, the tapping of domestic whole - latex has started, with 70% of the areas in Yunnan tapped and the supply of glue in Hainan increasing. In Southeast Asian producing areas, the tapping in northeastern Thailand has started, and the southern part will start tapping after May, resulting in an overall loose supply. Currently, the global supply and demand of rubber are both loose. Market speculation about the trade war and other macro - narratives, as well as the possible US automobile tariff, may seriously suppress global rubber demand, and rubber prices are generally weak. Attention should be paid to factors such as domestic rubber imports and inventory changes [11][12] 3.11 PVC - **Spot Information**: The mainstream price of East China 5 - type PVC is 4830 yuan/ton, unchanged from the previous period; the mainstream price of ethylene - based PVC is 5000 yuan/ton, down 50 yuan/ton; the price difference between ethylene - based and calcium - carbide - based PVC is 170 yuan/ton, up 50 yuan/ton [13] - **Market Analysis**: In terms of supply, the operating rate of PVC production enterprises last week was 77.70%, a week - on - week decrease of 2.64% and a year - on - year decrease of 0.85%. Among them, the operating rate of calcium - carbide - based PVC was 77.69%, a week - on - week decrease of 3.64% and a year - on - year increase of 0.18%, and the operating rate of ethylene - based PVC was 77.73%, a week - on - week decrease of 0.02% and a year - on - year decrease of 3.87%. In terms of demand, there has been no significant improvement in domestic downstream product enterprises, and transactions are mainly based on rigid demand. In terms of inventory, as of May 15, the PVC social inventory (47 samples) decreased by 3.07% week - on - week to 64.15 million tons, a year - on - year decrease of 26.96%. Among them, the inventory in East China was 58.39 million tons, a week - on - week decrease of 4.11% and a year - on - year decrease of 26.84%, and the inventory in South China was 5.77 million tons, a week - on - week increase of 8.86% and a year - on - year decrease of 28.09%. On May 21, the futures price rebounded. Previously, affected by macro - sentiment, the PVC futures price rebounded significantly, but there has been no obvious improvement in the fundamentals, and the upward space may be limited, with the futures price oscillating at a low level [13] 3.12 Soda Ash - **Spot Information**: The national mainstream price of heavy soda ash is 1421.25 yuan/ton, unchanged from the previous period. The mainstream prices in East China, North China, and Central China are 1450 yuan/ton, 1500 yuan/ton, and 1400 yuan/ton respectively, all unchanged from the previous period [15] - **Market Analysis**: In terms of supply, the overall operating rate of soda ash last week was 80.27%, a week - on - week decrease of 7.47%. The soda ash production was 67.77 million tons, a week - on - week decrease of 6.31 million tons, a decline of 8.52%. The scheduled maintenance has led to a decrease in supply. In terms of inventory, the manufacturer's inventory last week was 171.20 million tons, a week - on - week decrease of 1.07 million tons, a decline of 0.63%, and the enterprise inventory has not fluctuated much. It is understood that the social inventory is on a downward trend, with a decline of more than 1 million tons and a total of more than 36 million tons. The demand is average, and downstream enterprises replenish inventory for low - priced goods on a rigid - demand basis but still resist high - priced goods. Overall, due to the combination of plant maintenance and the realization of new production capacity, the futures market is expected to continue to oscillate widely in the short term. Attention should be paid to plant maintenance dynamics and unexpected events [15]

1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core Views - **LLDPE & PP**: The overall trading was weak on Monday, and market sentiment deteriorated. For plastics, maintenance increased and some production shifted before early June, with low imports. Demand improved in the short - term due to tariff cuts, and there was an expectation of inventory reduction. For PP, the maintenance peak was in late May, and subsequent supply pressure would increase. Demand had short - term benefits but mid - term concerns. The static fundamentals were okay. For single - side trading, it was advisable to go short on rallies, and the LP spread was expected to widen [4]. - **PVC & Caustic Soda**: For caustic soda, in the short - term, supply pressure was limited during the concentrated maintenance period. Demand was supported by the potential resumption of some alumina production and new production lines. The purchase price of mainstream Shandong factories increased, and the futures price might rise further, but there were risks. It was recommended to stay on the sidelines, and aggressive investors could try positive spreads cautiously. For PVC, the short - term rebound was supported by macro - stimulation, export, and supply - demand factors, but there was an over - supply pressure in the long - term. It was expected to fluctuate in the short - term, with a resistance level of around 5100 for the 09 contract [26]. - **Polyester Industry Chain**: For PX, short - term supply was tight, and demand was supported, but the upside was limited. PX09 was expected to fluctuate in the range of 6600 - 7000, and PX9 - 1 was in a short - term positive spread situation. For PTA, the supply - demand situation was expected to weaken. TA09 was expected to fluctuate in the range of 4600 - 5000, and TA9 - 1 was short - term positive spread and medium - term negative spread. For MEG, there was an expectation of inventory reduction, and short - term support was strong. It was advisable to sell put options on EG2509 - P - 4300 and go for positive spreads on EG9 - 1. For short - fiber, the absolute price was expected to adjust, and attention could be paid to the opportunity to widen the processing margin. For bottle - chips, the absolute price followed the raw materials, and attention could be paid to the opportunity to widen the processing margin at the lower end of the range [30]. - **Crude Oil**: Oil prices were oscillating, and the future logic would shift from macro to fundamental factors. If OPEC's actual production increase was as expected, the market would be under pressure; otherwise, the pressure would be relieved. There was still a short - term geopolitical premium. Oil prices were likely to fluctuate within a certain range. The recommended trading strategy was a band - trading approach, with the WTI range at [59, 69], Brent at [61, 71], and SC at [450, 510]. It was advisable to buy volatility in options trading [34]. - **Methanol**: The port inventory showed an inflection point, and the expected increase in imports would lead to inventory accumulation and a weaker basis. The 09 contract was expected to decline in the short - term, and it was advisable to add positions at 2350, targeting 2050 - 2100. It was also advisable to reduce short - positions on the 69 reverse spread [37]. - **Styrene**: Styrene rebounded strongly. Tariff cuts improved demand expectations, and the inventory was at a low level. However, there were risks, including high inventory in the 3S products and weak pure - benzene supply - demand. It was expected to fluctuate in the short - term and be bearish in the medium - term. Attention could be paid to the resistance level of 7800 - 7900 for the near - month contract, and the opportunity for the EB - BZ spread to widen [42]. 3.

1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views Steel Industry - The steel industry presents a structure of high production, low inventory, weak cost support, and expected demand recovery. It is about to face the seasonal off - season and the possibility of weakening manufacturing demand (exports). The price is expected to oscillate at a low level, and it is recommended to wait and see for now [1]. Iron Ore Industry - This week, the daily average iron ore production has peaked and declined, while the port clearance volume has slightly increased. It is expected that the iron ore production will remain at a high level in the short term. The iron ore is slightly de - stocked under high iron ore production, and the steel mill inventory remains low. The terminal demand of finished products determines the sustainability of high - level iron ore production. It is expected that the iron ore will oscillate in the short term [4]. Silicon and Manganese Industry - For silicon iron, the daily production has declined, the supply pressure has been gradually relieved, and the factory inventory has gradually decreased, but the overall inventory is still at a medium - high level. For silicon manganese, the production is accelerating to decline, the supply and demand contradiction is limited, and the price is expected to oscillate, stabilize, and rebound [5]. Coke and Coking Coal Industry - The coke and coking coal futures showed a weak oscillating trend last week. The supply - demand pattern is still loose in the short term. It is recommended to short the 2509 contracts of coke and coking coal at high prices and continue to hold the arbitrage strategy of long hot - rolled coils and short coke/coking coal [6]. 3. Summary by Directory Steel Industry - **Prices and Spreads**: The prices of most steel products decreased.

The start - up rates of both decreased [5]. - **Demand**: The demand for silicon iron and silicon manganese remained relatively stable [5]. - **Inventory**: The inventory of 60 sample silicon iron enterprises decreased by 1.0 tons (- 11.8%), and the inventory of 63 sample silicon manganese enterprises increased by 2.5 tons (13.9%) [5]. Coke and Coking Coal Industry - **Prices and Spreads**: The prices of coke and coking coal decreased. For example, the price of first - class wet - quenched coke in Shanxi decreased by 50 yuan/ton (- 3.84%), and the price of coking coal (Shanxi warehouse - receipt) decreased by 20 yuan/ton (- 1.9%) [6]. - **Supply**: The coke production increased slightly, and the coking coal production remained at a relatively high level. The domestic coal mines continued to resume production, and the Mongolian customs clearance volume increased from a low level [6]. - **Demand**: The iron ore production showed signs of peaking and declining, and the downstream users' replenishment was mainly on - demand [6]. - **Inventory**: The coke inventory in coking plants continued to decline, the port inventory decreased slightly, and the steel mill inventory was low. The coking coal inventory in mines continued to accumulate, and the downstream inventory was at a low level [6].
