1. Report Industry Investment Rating No information provided in the report. 2. Core Views of the Report Protein Meal - South American soybeans' impact on the market is gradually weakening. Brazilian soybeans mainly affect the market through the trend of Brazilian basis. In June, the high - temperature weather in the US continues, with excessive rainfall in the east and significantly lower - than - normal rainfall in the western part of the Midwest, which may damage soybean growth. CBOT soybeans will fluctuate between 950 - 1150 before variables change and may rise if variables occur. In June, domestic imported soybeans will arrive at ports intensively, oil mills will operate at a high level, and soybean meal inventory accumulation may accelerate, causing spot and basis prices to decline. Dalian soybean meal may follow the trend of US soybeans [1][124]. Oils - In June, there is a high possibility that US soybean oil will oscillate and decline from a high level due to the uncertainty of the US biodiesel policy. Malaysian palm oil may continue to accumulate inventory in May, and there is a high risk of a market decline in June. Domestic oils have an obvious oversupply situation in June, with soybean oil inventory accumulating faster, and palm oil and rapeseed oil inventories remaining stable. Domestic oil demand is weak, and the market may follow international oils. Lianpalmoil may continue to oscillate weakly, Zheng rapeseed oil may be supported by policies and oscillate strongly, and the soybean - palm oil spread is expected to continue to widen [2][125][126]. 3. Summary by Relevant Catalogs Part One: Market Review - In May, CBOT soybeans oscillated and closed higher. At the beginning of May, they showed a low - level oscillation trend. Later, positive factors such as the improvement of US soybean export prospects, the tightening of new - year supply, and the increase in US biodiesel blending ratio pushed up the price. Domestic soybean meal was significantly weaker than the external market. International oils showed differentiated trends, with US soybean oil reaching a high and then falling, and Malaysian palm oil oscillating downwards. Domestic oils followed international oils but did not break out of the previous oscillation range [4][5]. Part Two: Protein Meal - **Global Soybean Production Forecast**: USDA's May report shows that the global soybean production is expected to increase for the fourth consecutive year in the 25/26 season, with heavy supply pressure from South America. The supply pressure is most significant during the concentrated listing period of South American soybeans from May to June [9]. - **South American Soybean Situation**: Argentina was affected by rainfall during the harvest period, which may reduce production. Brazilian soybean production is a foregone conclusion, and its impact on the market is mainly reflected in the Brazilian basis. The decline of Brazilian basis may slow down in June and may stop falling and stabilize [10][15][19]. - **US Soybean Situation**: In the 25/26 season, US soybean supply is tight, with low tolerance for yield reduction. The planting progress in 2025 is ahead of schedule, but the weather may be characterized by "flood in the east and drought in the west", which may damage soybean growth. US soybean exports and crushing demand in the 25/26 season have great uncertainties. Before variables change, CBOT soybeans will oscillate between 950 - 1150 and may rise if variables occur [26][29][40]. - **Domestic Protein Meal Situation**: In June, domestic imported soybeans will arrive at ports intensively, oil mills will operate at a high level, and soybean meal inventory accumulation may accelerate, causing spot and basis prices to decline. Dalian soybean meal may follow the trend of US soybeans [64]. Part Three: Oils - **US Soybean Oil**: USDA estimates that the production and demand of US soybean oil will increase in the 25/26 season, but the market sentiment has changed from optimism to pessimism due to the uncertainty of the biodiesel policy. In June, US soybean oil may oscillate and decline from a high level [66][69][74]. - **Malaysian Palm Oil**: Since March, Malaysian palm oil production has been increasing. In May, production may exceed demand, leading to inventory accumulation. In June, production may slightly decline, and exports may increase. The market has a high risk of decline and needs export demand and biodiesel policies to boost [75][79][84]. - **Canadian Rapeseed**: USDA estimates that the global rapeseed production will increase by 5% in the 25/26 season, and the supply will be better than that in the 24/25 season. Canadian rapeseed production is expected to increase by nearly 4%, but the inventory is still at a low level, with limited tolerance for yield reduction [90][93]. - **Domestic Oils**: In June, domestic oils have an obvious oversupply situation, with soybean oil inventory accumulating faster, and palm oil and rapeseed oil inventories remaining stable. Domestic oil demand is weak, and the market may follow international oils. Lianpalmoil may continue to oscillate weakly, Zheng rapeseed oil may be supported by policies and oscillate strongly, and the soybean - palm oil spread is expected to continue to widen [123]. Part Four: Conclusions and Operational Suggestions - **Protein Meal**: South American soybeans' impact on the market is weakening. In June, US weather may affect soybean growth, and there are uncertainties in US soybean exports and crushing demand. CBOT soybeans will oscillate in a range and may rise if variables occur. Domestic soybean meal inventory may accumulate faster, and spot and basis prices may decline. Dalian soybean meal may follow US soybeans [124]. - **Oils**: US soybean oil may oscillate and decline from a high level in June. Malaysian palm oil has a high risk of decline. Domestic oils have an oversupply situation, with soybean oil inventory accumulating faster, and palm oil and rapeseed oil inventories remaining stable. Lianpalmoil may oscillate weakly, Zheng rapeseed oil may oscillate strongly, and the soybean - palm oil spread is expected to widen [125][126]. - **Operations**: For soybean meal, adopt low - level buying or selling put options. For palm oil, short at the upper limit of the range or sell call options. In arbitrage, go long on the soybean - palm oil spread and short on the oil - meal ratio [127][128][129].

Report Industry Investment Rating - Not provided in the document Core Viewpoints - The domestic methanol supply remains high as some previously overhauled methanol plants resumed stable operation in May. Although the short - term available supply in coastal areas is scarce, the significant increase in imported cargoes at coastal public terminals is expected, with an estimated arrival volume of 930,000 tons in mid - to - late May, leading to limited upward potential in prices [44]. Summary by Directory 1. Market Review - The closing price of the methanol main contract MA2509 was 2,284 yuan/ton, with a weekly increase of 2.42%. It shed 50,000 lots, and the open interest was 710,000 lots. The port basis continued to weaken [6]. - Inland methanol prices first declined and then rose. The weekly average price in Inner Mongolia was 2,116 yuan/ton, up 0.76% from last week. Some olefin enterprises continued to make external purchases, and the overall transaction center moved upward. The coastal methanol market rebounded from the low level. The weekly average price in Taicang was 2,429 yuan/ton, up 1.07% from last week. With the improvement of macro - sentiment and the restart expectation of coastal downstream, the negotiation and transaction center of coastal methanol moved slightly upward [9]. - In the overseas market, the reference negotiation price of non - Iranian methanol cargoes arriving in the far - month was 265 - 268 US dollars/ton, and that of Iranian cargoes arriving in the far - month was +0.7 - 1.5%. A 1.75 - million - ton methanol plant in Southeast Asia was under maintenance. As of now, two methanol plants in Southeast Asia with a total capacity of 3.45 million tons were shut down, and the CFR Southeast Asia price was 335 - 340 US dollars/ton [12]. 2. Methanol Fundamental Analysis - **Methanol Operating Rate**: As of May 15, the overall domestic methanol plant operating rate was 75.50%, down 0.15 percentage points from last week but up 10.36 percentage points from the same period last year. The operating rate in the northwest region was 82.42%, down 1.15 percentage points from last week but up 13.11 percentage points from the same period last year [16]. - **Methanol Imports and Exports**: The import arbitrage window was open, and the re - export profit remained relatively high [18]. - **Methanol Port Inventory**: The coastal methanol inventory this week was 629,000 tons, a week - on - week increase of 10,000 tons. The overall coastal inventory increased steadily, and the raw material inventory of downstream factories also rose. The estimated tradable methanol supply in the coastal area was 254,000 tons, and the short - term available supply was scarce. It is expected that the volume of imported methanol vessels arriving in China in mid - to - late May will be 930,000 tons [22]. - **Crude Oil and Natural Gas**: The international natural gas price slightly declined to around 3.7 US dollars/MMBtu, and the import cost of natural - gas - based methanol increased to around 1,780 yuan/ton [25]. - **Methanol Upstream - Coal**: The domestic thermal coal market remained weak this week, with coal prices continuing to decline. The theoretical profit of coal - based methanol production in Inner Mongolia increased slightly [28]. - **Methanol Downstream Price and Operating Rate**: The overall weighted operating rate of methanol downstream was about 72.2%, a week - on - week increase of 1%. The weighted operating rate of traditional downstream was about 58.8%, a week - on - week decrease of 2% [30]. - **Methanol Downstream - Traditional Downstream**: Not elaborated in detail in the text. - **Methanol Downstream - MTO**: The average operating rate of methanol - to - olefin plants this week was 77.52%, up 1.53 percentage points from last week. The average load of externally - purchased MTO plants was 75.68%, up 8.51 percentage points from last week. Inner Mongolia Baofeng (Phase I) resumed production, Zhongmei Yulin entered maintenance on May 10, Ningxia Baofeng (Phase II) shut down this week for a planned one - month maintenance. Zhongmei Mengda has a maintenance plan in late June, and Sierbang plans to restart in late May [41]. 3. Future Outlook - The domestic methanol supply remains high. Although the short - term available supply in coastal areas is scarce, the expected increase in imported cargoes will limit the upward potential of prices [44].

Report Industry Investment Rating - Not provided Core View of the Report - The better - than - expected result of the China - US negotiation led to a significant drop in tariffs, which repaired market sentiment and drove the rebound of hot - rolled coils. This week, the demand for hot - rolled coils increased slightly, and the demand for building materials, cold - rolled coils, and medium - thick plates all rose, with inventory continuing to decline. The better - than - expected result of the China - US trade negotiation falsified the pessimistic expectation on the export side, and the market re - examined the supply - demand situation and expectations, resulting in a short - term corrective rebound. However, from the perspective of the steel supply - demand situation, future demand still has great uncertainty, and hot - rolled coils face significant pressure. In terms of trends, there is a short - term rebound but significant resistance above. The operating strategy is to participate in the short - term [10][52]. Summary According to the Directory 1. Trend Review - The better - than - expected result of the China - US negotiation led to a significant drop in tariffs, which repaired market sentiment and drove the rebound of hot - rolled coils [10]. 2. Basis and Spread - **Hot - rolled coil basis**: The 01 basis is 28, the 05 basis is 38, and the 10 basis is 40 [17]. 3. Supply - Demand Analysis - **Hot - rolled coil profit**: The 01 contract's on - disk profit is 430, the 05 contract's on - disk profit is 212, the 10 contract's on - disk profit is 360, and the production profit is 191 [31]. - **Output**: The hot - rolled coil output is 311.98, the cold - rolled coil output is 87.86, the rebar output is 226.53, and the output of the five major steel products is 868.35 [33]. - **Inventory**: The hot - rolled coil inventory is 347.57, the cold - rolled coil inventory is 169.2, the rebar inventory is 619.87, and the inventory of the five major steel products is 1430.66 [38]. - **Export**: Exports remain strong [47]. 4.
