Report Industry Investment Ratings No specific industry investment ratings are provided in the given content. Core Views of the Report - The overall global risk appetite has increased as the US Treasury yield first soared and then declined. Domestically, the central bank's interest - rate cuts and commercial banks' reduction of deposit rates have further loosened monetary policy, which is conducive to boosting domestic risk appetite in the short term [2]. - Different asset classes have different trends and operation suggestions. For example, the stock index may fluctuate in the short term, and it is advisable to be cautiously long; the bond market may remain high - level volatile in the short term, and it is recommended to observe carefully; various commodity sectors also have their own characteristics and operation strategies [2]. Summary by Related Catalogs Macro - finance - Overseas: The deterioration of the US fiscal outlook initially led to concerns about US Treasury demand, causing a sharp rise in Treasury yields. Subsequently, the passage of Trump's comprehensive tax - cut bill by the US House of Representatives and its submission to the Senate for review led to a decline in Treasury yields from recent highs, boosting market sentiment [2]. - Domestic: In April, domestic domestic demand slowed down and was lower than expected, while exports far exceeded expectations, and the role of exports in driving the economy remained strong. The central bank cut the 1 - year and 5 - year LPR rates by 10BP, and commercial banks reduced deposit rates, further loosening monetary policy, which helps boost domestic risk appetite in the short term [2][3]. Stock Index - Affected by sectors such as non - metallic materials, batteries, and semiconductor materials, the domestic stock market continued to decline slightly. Given the current economic situation and loose monetary policy, it is advisable to be cautiously long in the short term [3]. Precious Metals - Gold: After the continuous decline of the US dollar, it rebounded, and the gold market rose and then fell on Thursday. Moody's downgrading of the US credit rating promoted safe - haven demand. The passage of Trump's large - scale tax and spending cut bill reduced policy uncertainty. The long - term global de - dollarization trend provides long - term support for gold. For silver, due to the weak manufacturing industry and supply - chain impacts, it is advisable to maintain a wait - and - see attitude in the short term [3]. Black Metals Steel - The domestic steel spot and futures markets weakened on Thursday, with low trading volumes. Real - world demand continued to decline, and the apparent consumption of the five major steel products decreased by 9.2 tons week - on - week. Although steel production increased, considering the high profitability of steel mills, short - term supply may remain high. The short - term steel market may be treated with an interval - oscillation mindset [4][5]. Iron Ore - On Thursday, the spot and futures prices of iron ore declined slightly. With high steel - mill profitability, the probability of short - term high iron - water production is high. Although the global iron - ore shipment volume increased by 318.8 tons week - on - week, the arrival volume decreased by 289.6 tons. The port inventory decreased by 119.36 tons on Monday. Iron ore is still strong in the short term, and the strategy of shorting on rallies can be continued in the medium term [5]. Silicon Manganese/Silicon Iron - On Thursday, the spot prices of silicon iron and silicon manganese declined slightly, while the futures prices rebounded significantly. The main reasons were the inclusion of manganese ore in high - critical minerals by the South African government and the market rumor of a port workers' strike. However, the impact of these two news remains at the expected level. The fundamentals of silicon manganese are still weak, and its price increase is not expected to be sustainable, and it may fluctuate in the bottom - interval later [6]. Energy and Chemicals Crude Oil - OPEC+ may increase daily production by 411,000 barrels starting in July, mainly from Saudi Arabia. Coupled with concerns about economic growth slowdown and weakening energy demand caused by the US - led trade war, the market is worried about oversupply, and the price will remain weakly volatile [7]. Asphalt - The price of asphalt fluctuates weakly following crude oil. Current demand is average, and the basis in major consumption areas has declined significantly. With the increase in production after profit recovery and the stagnation of inventory reduction, it will continue to fluctuate at a high level following crude oil in the short term [7]. PX - PX has declined slightly recently, and the short - term profit is still high, so the later supply will not decrease significantly. With the reduction of PTA maintenance and the increase in demand, PX will remain in a tight - balance situation, and the upstream profit will expand again. However, if downstream production cuts occur, PX may face a risk of decline [7]. Other Chemical Products - Each chemical product such as PTA, ethylene glycol, short - fiber, methanol, PP, LLDPE, and urea has its own supply - demand situation and price trends. For example, PTA may be in a weakly - oscillating pattern; ethylene glycol is expected to remain high - level and weakly volatile; short - fiber will continue to oscillate; methanol prices are still under pressure; the fundamentals of PP are not optimistic; LLDPE price increase is limited; and urea prices are strongly volatile in the short - and medium - term and under pressure in the long - term [8][9][10]. Non - ferrous Metals Copper - The passage of a tax and spending bill by the US House of Representatives and the manufacturing and service PMI data in the euro area have certain impacts. The social inventory of copper has increased, and the processing fee of copper ore is at a historical low. As it is about to enter the off - season of demand, the reduction of Sino - US tariffs may boost demand. The copper price will oscillate in the short term, and opportunities for shorting can be sought in the medium term [11]. Aluminum - The global primary aluminum supply was in surplus in March and from January to March. China's primary aluminum imports increased in April. The market generally has a bearish view, but it is advisable to be cautious about shorting in the short term and wait for a better entry point [13]. Tin - The resumption of tin production in Myanmar and Congo is in progress, but the supply constraint still exists, and the processing fee of tin concentrate remains at a historical low. The demand is about to enter the off - season, and the downstream mainly conducts rigid - demand purchases. The short - term tin price will oscillate, supported by the tight supply of mines and low smelting start - up rates [14]. Agricultural Products US Soybeans - The overnight CBOT soybean futures closed higher. The export sales of US soybeans increased in the week ending May 15. The early - stage planting conditions in US soybean - producing areas are mild, and the drought - affected area has decreased [15]. Soybean Meal - The national dynamic full - sample oil - mill operating rate declined slightly. The basis trading volume of domestic soybean meal has increased significantly. The soybean meal futures price rebounded after testing the 2800 - 2850 range, and the support for the horizontal - range of M09 has been strengthened in the short term [15]. Palm Oil - US policies have caused greater fluctuations in the US soybean - oil market. The price of Malaysian palm oil is expected to fluctuate between 3,750 and 4,050 ringgit per ton in May. The production of Malaysian palm oil increased from May 1 - 20, and the export also increased [15][16]. Live Pigs - After the May holiday, the terminal demand was weak, and the slaughtering enterprises faced difficulties in selling white - striped pigs. The supply was stable, but as the consumption off - season becomes more prominent, the spot price is under pressure. Attention should be paid to the risk of accelerated slaughter by large - scale farms and the pressure of selling large - sized pigs in late May or early June [16]. Corn - The futures price of corn has declined significantly recently, and the spot price has also been affected. With the listing of new - season wheat, the market's bullish sentiment has weakened. The deep - processing profit has been in continuous losses, and the operating rate has remained stable. The purchase of wheat as a substitute for corn by downstream feed enterprises has increased [16].

Group 1: Investment Ratings and General Market Outlook - No explicit report industry investment rating provided [1] - The core view is that various commodities show different trends based on factors such as national policies, trade negotiation results, and supply - demand fundamentals. Market sentiment has been affected by factors like China - US trade talks and inflation data [1] Group 2: Macro - Financial Sector - **Stock Index**: Since April, with the support of national policies and Central Huijin's funds, the stock index has recovered the technical gap formed by the tariff shock on April 2. The current risk - return ratio of chasing the rise is not high. Holders of long positions can consider reducing positions on rallies [1] - **Treasury Bonds**: Asset shortage and weak economy are favorable for bond futures, but the central bank's short - term reminder of interest - rate risks suppresses the upward space [1] - **Gold**: Short - term market risk appetite has recovered, and the gold price may enter a consolidation phase, but the medium - to - long - term upward logic remains unchanged [1] - **Silver**: Overall, it follows gold, but an unexpected tariff result will benefit the commodity attribute of silver, so the short - term resilience of the silver price may be stronger than that of gold [1] Group 3: Non - Ferrous Metals Sector - **Copper**: The result of China - US trade negotiations exceeded expectations, and short - term market sentiment has improved. However, the copper price has significantly rebounded and may fluctuate [1] - **Aluminum and Alumina**: The aluminum electrolysis industry has no obvious contradictions. With the unexpected result of China - US trade negotiations, the aluminum price continues to rebound. Supply disturbances of bauxite and alumina have increased, and the supply - demand pattern of alumina has improved. The short - term price may further rebound [1] - **Zinc**: Although the macro sentiment has improved, the terminal demand has weakened significantly in the off - season, and with the inflow of imported goods, the zinc price remains weak [1] - **Nickel and Stainless Steel**: US inflation has cooled more than expected, and the result of China - US talks has exceeded market expectations. The export order expectation of terminals has improved, and market risk appetite is expected to recover. The Indonesian resource tax policy has been implemented, and the premium of nickel ore is high. There are rumors of a mining ban in the Philippines, but the implementation is difficult. The nickel price fluctuates in the short term, and there is still pressure from the surplus of primary nickel in the medium - to - long term. The short - term stainless steel futures fluctuate and rebound, but there is still supply pressure in the medium - to - long term [1] - **Tin**: With the unexpected result of China - US talks and improved macro sentiment, the tin price is expected to rebound. The resumption of production in Wa State needs to be continuously monitored [1] - **Industrial Silicon**: Supply is strong, demand is weak, it has entered the low - valuation range, demand has not improved, inventory pressure has not been relieved, and the China - US tariff negotiation result is unexpected [1] - **Polycrystalline Silicon**: The number of registered warehouse receipts is extremely small, the first delivery is approaching, the futures price is at a discount to the spot price, and the willingness to register warehouse receipts is low, and the China - US tariff negotiation result is unexpected [1] - **Lithium Carbonate**: Supply has not further shrunk, the visible inventory has continued to accumulate, the downstream raw material inventory is at a high level, downstream still maintains rigid - demand purchases at low prices, and the China - US tariff negotiation result is unexpected [1] Group 4: Ferrous Metals Sector - **Steel Products (Rebar, Hot - Rolled Coil)**: The trade turmoil has intensified the pressure on the export chain. The short - term risk appetite is slightly poor, and the opening price dives downward [1] - **Iron Ore**: The tariff policy affects market sentiment, and the iron ore with strong financial attributes is under short - term pressure [1] - **Manganese Silicon**: There is still an expectation of decline under the expectation of manganese ore surplus, and the variety has heavy warehouse - receipt pressure [1] - **Silicon Iron**: The cost is dragged down by thermal coal, but the production reduction in the production area is large, and the supply - demand situation has become tight [1] - **Glass**: The situation of weak supply and demand continues. With the arrival of the rainy season, there are concerns about weakening demand, and the price continues to be weak [1] - **Soda Ash**: There are many overhauls in May, and the direct demand is okay, but there is medium - term supply surplus, and the price is under pressure [1] - **Coking Coal and Coke**: The supply and demand of coking coal and coke are relatively surplus and are short - positioned in the sector. It is recommended that industrial customers actively seize the opportunities of cash - and - carry arbitrage and selling hedging when the market rebounds to a premium. Consider participating in the JM9 - 1 calendar spread arbitrage [1] Group 5: Agricultural Products Sector - **Palm Oil**: The rise in crude oil will drive the rebound of palm oil, and the China - US talks will drag down the soybean - palm oil price spread. It is recommended to short after the crude oil price falls [1] - **Soybean Oil**: China - US talks are expected to have a negative impact on soybean oil sentiment in the short term, dragging down the soybean - palm oil price spread. It is recommended to wait and see [1] - **Rapeseed Oil**: The northern rapeseed - producing areas in Europe are still dry, which is not conducive to the formation of rapeseed yield per unit in the bolting stage. The China - Canada relationship is still uncertain. If Canada cancels the additional tariffs on China, it is expected to cause a large decline. Consider long - volatility strategies [1] - **Cotton**: In the short term, there are disturbances such as trade negotiations and weather premiums for US cotton. In the long term, macro uncertainties are still strong. The domestic cotton - spinning industry has entered the consumption off - season, and there are signs of inventory accumulation in downstream finished products. It is expected that the domestic cotton price will maintain a weak and fluctuating trend [1] - **Sugar**: According to the latest forecast of the Brazilian National Supply Company, Brazil's sugarcane production in the 2025/26 season is expected to be 663.4 million tons, a 2% decline from the previous year. The sugar production is expected to reach a record 4.59 million tons, a 4% increase from the previous year. If the crude oil price continues to be weak, it may affect the sugar - making ratio in Brazil's new crushing season and lead to an unexpected increase in sugar production [1] - **Corn**: The overall situation of deep - processing in the Northeast has stabilized, the decline in Shandong's deep - processing has slowed down. The import corn auction policy and China - US economic and trade talks have a negative impact on sentiment. The market回调 in the short term. It is recommended to buy on dips and pay attention to the C07 - C01 calendar spread arbitrage [1] - **Soybean Meal**: There is no driving force for speculation in US soybean planting. The domestic market continues to digest the negative factors of spot pressure and Brazilian selling pressure, and the market is expected to fluctuate [1] - **Pulp**: After the positive impact of the unexpected China - US trade negotiation on pulp futures is realized, the fundamentals still lack upward momentum, and it is expected to fluctuate [1] - **Logs**: The arrival volume of logs remains high, the overall inventory is high, and the price of terminal products has declined. There is no short - term positive factor, and it is expected to fluctuate at a low level [1] - **Pigs**: With the continuous repair of the pig inventory, the slaughter weight continues to increase. The market expectation is obvious, the futures price is at a large discount to the spot price, and there are no bright spots in the downstream [1] Group 6: Energy and Chemical Sector - **Crude Oil - Related (Fuel Oil, Palm Oil)**: The result of China - US trade negotiations far exceeds market expectations, reducing concerns about weakening demand. After a sharp decline, there is a demand for rebound and repair [1] - **BR Rubber**: The result of China - US trade negotiations is unexpected. In the short term, the raw material cost support is strengthened due to rainfall in the production area. In the medium - to - long term, the fundamentals are loose, and demand is weak, and the price is expected to decline [1] - **PTA, Short - Fiber, and Related Products**: The upstream PX device is under intensive maintenance, and the internal - external price difference of PX has been significantly repaired. The demand for PTA is supported by the high load of polyester. The PTA shortage strengthens the cost support for short - fiber, and short - fiber performs strongly under the high basis [1] - **Ethylene Glycol**: Ethylene glycol devices are under maintenance, large - scale devices in Jiangsu and Zhejiang have reduced their loads, and coal - based devices have started to be overhauled [1] - **Pure Benzene and Styrene**: The improvement of China - US tariff policies stimulates market speculative demand, the pure benzene price gradually strengthens, the profit of the reforming device declines, and the downstream demand for styrene is expected to pick up [1] - **Methanol**: The basis strengthens, the trading volume is average. In the short term, the methanol price fluctuates in a range and is slightly strong. In the medium - to - long term, the methanol spot market may change from strong to weak and fluctuate [1] - **PE, PP, PVC, and Caustic Soda**: For PE, the basis strengthens, and the trading volume is general. It fluctuates slightly strongly in the short term and may change from strong to weak in the medium - to - long term.

1. Report Industry Investment Ratings No specific industry investment ratings are provided in the report. 2. Core Views of the Report - The global risk appetite has significantly increased due to the US releasing signals of trade relaxation. The short - term risk preference of the domestic market is strongly supported by factors such as the Chinese foreign exchange regulator's measures to prevent RMB exchange - rate overshooting, strengthened domestic policy support, and the US - China trade relaxation signals. Different asset classes have different trends: the stock index will rebound with short - term fluctuations, treasury bonds will fluctuate at a high level, and different commodity sectors also show different trends [1]. 3. Summary by Related Catalogs 3.1 Macro - finance - Overseas: The IMF has significantly downgraded the global economic outlook due to the impact of Trump's high tariffs. The US Treasury Secretary said that the trade tension between the US and China will ease, and Trump has no intention of firing Fed Chairman Powell but hopes for a rate cut, leading to a sharp rebound in the US dollar and a significant decline in global risk appetite. Domestic: The Chinese foreign exchange regulator's measures have relieved the RMB exchange - rate pressure, and the short - term risk preference of the domestic market is strongly supported [1]. 3.2 Stock Index - Driven by sectors such as logistics trade, cross - border payment, and port shipping, the domestic stock market has risen slightly. With the relief of RMB exchange - rate pressure and strengthened policy support, short - term cautious long positions are recommended [2]. 3.3 Precious Metals - The precious metals market continued to rise on Tuesday. The US government's credit damage, trade policy uncertainty, geopolitical risks, and other factors will support the short - term strength of gold.

Silver follows gold but has greater correction pressure [2][3]. 3.4 Black Metals 3.4.1 Steel - The steel futures and spot markets rose and then fell on Tuesday, with a significant decline in trading volume. The real demand recovery lacks sustainability, and the supply remains high. The short - term steel market is recommended to be treated with an interval - oscillation mindset [4]. 3.4.2 Iron Ore - The iron ore futures and spot prices fell slightly on Tuesday. The ore fundamentals are still good, but if the steel prices remain low, iron ore may experience a supplementary decline [5]. 3.4.3 Silicon Manganese/Silicon Iron - The spot prices of silicon iron and silicon manganese remained flat on Tuesday.

The short - term ferroalloy prices are recommended to be treated with an interval - oscillation mindset [6]. 3.5 Energy and Chemicals 3.5.1 Methanol - The methanol price in Taicang fluctuated slightly. The supply and demand pressure is expected to be small. The 05 contract price will mainly oscillate, and the 09 contract has a large supply - expectation pressure, waiting for a short - selling opportunity on a rebound [7]. 3.5.2 PP - The domestic PP market quotation was slightly adjusted. Although there is new production capacity, the supply reduction on the supply side will relieve the overall pressure, and the price is expected to oscillate and recover [8]. 3.5.3 LLDPE - The PE market price was adjusted. The near - month price has limited downward space due to low - inventory support. The 09 contract's supply and demand situation needs to be tracked, and the long - term price is still under pressure due to new production capacity release [9]. 3.6 Non - ferrous Metals 3.6.1 Copper - The copper price rose due to the weakening of the US dollar.
