1. Report Industry Investment Rating No information provided. 2. Core Viewpoints of the Report - The US corn report has lowered the yield per unit, but the production remains at a high level. The price of US corn has declined and is expected to trade in a narrow range. China has imposed a 15% tariff on US corn, with a total of 26% tariff within the quota, and a 22% tariff on US sorghum. The import profit of foreign corn is relatively high, with the December import price from Brazil at 2,135 yuan. The spot price of corn in the Northeast and North China is falling, and the price difference between the two regions is widening. The domestic breeding demand is still weak, and the inventory of downstream feed enterprises is low. The corn spot price is expected to be relatively stable in the short term. With the large - scale listing of new - season corn at the end of September, the spot price of corn is likely to continue to fall [5][6]. - The number of trucks arriving at deep - processing plants in Shandong has increased, and the spot price of corn in Shandong is weak. The spot price of starch in Shandong and the Northeast is also weak. This week, the inventory of corn starch has decreased. The current starch price mainly depends on the corn price and downstream stocking. The price of by - products is still strong. In the medium to long term, due to weak demand, starch enterprises will be in a long - term loss state. The 01 starch contract is expected to trade in a narrow range at the bottom in the short term [7]. 3.

China's tariff policies on US corn and sorghum have been adjusted. The import profit of foreign corn is high. The spot price of corn in the North is stable, while that in the Northeast and North China is falling. The price difference between Northeast and North China corn is widening, and the price difference between wheat and corn is also widening. The domestic breeding demand is weak, and the inventory of downstream feed enterprises is low. With the large - scale listing of new - season corn at the end of September, the spot price of corn is expected to continue to fall [5][6]. 3.2.2 Starch - The spot price of corn in Shandong is weak, and the spot price of starch in Shandong and the Northeast is also weak. This week, the inventory of corn starch has decreased. The current starch price depends on the corn price and downstream stocking. The price of by - products is strong.

The 01 starch contract is expected to trade in a narrow range at the bottom in the short term [7]. 3.3 Trading Strategies - Unilateral: US corn has support at 400 cents per bushel. Consider a light - position long on the 01 contract with a stop - loss set [9]. - Arbitrage: Hold a wait - and - see attitude [10]. 3.4 Corn Options - Option strategy: Adopt a short - term strategy of accumulating puts and calls with rolling operations [11]. 3.5 Relevant Attachments - The attachments include charts showing the spot price of corn in various regions, the basis of the corn 01 contract, the 1 - 5 spread of corn, the 1 - 5 spread of corn starch, the basis of the corn starch 01 contract, and the spread of the corn starch 01 contract, which help to visually analyze the price trends and relationships of corn and corn starch [14][15][18][20].

Report Summary 1. Investment Rating The report does not mention the industry investment rating. 2. Core Viewpoints - The domestic economic "weak reality" continues, and the economic indicators in Q4 face the unfavorable impact of the higher base after September 24 last year. The central bank's attitude of caring for liquidity remains unchanged, which supports the bond market. However, the "anti-involution" policy and the high prosperity of some technology industries, along with the easing of geopolitical disturbances and the Fed's interest rate cut, make the "strong expectation" the dominant force in the macro narrative. The potential adjustment of public bond fund redemption fees and tax policies exacerbates bond market volatility. In the short term, bond market sentiment is still sluggish, but treasury bonds have an irreplaceable role in hedging potential expectation differences [3][57]. - In terms of operations, in the short term, investors are advised to be cautious about the TL contract and hold a small amount of long positions in bond futures. The TF contract may be the best option. For arbitrage, if the market expectation is revised or extreme sentiment causes an over - adjustment in the bond market, the TL contract can be considered for flattening the curve and reverse arbitrage operations, but the timing needs to be observed [4][59]. 3. Summary by Directory 3.1 Market Trend Review - In September, the bond market performance was somewhat differentiated. The short - and medium - term bonds were generally in a volatile range, while the long - term bonds adjusted significantly under the influence of "strong expectations" and bond fund redemption pressure, and the yield curve became steeper. As of September 29, the monthly returns of the TS, TF, T, and TL main contracts were - 0.09%, - 0.03%, - 0.15%, and - 2.44% respectively. The overall weak bond market sentiment made the market valuation slightly low, and the IRR of the main contracts of bond futures at all maturities was around 1.3 - 1.4% [6]. 3.2 "Weak Reality" Continues, "Strong Expectation" Dominates the Narrative - The domestic economic data in August released in September continued to weaken marginally, with both supply and demand falling short of expectations. Investment, consumption, and foreign trade all showed different degrees of decline. The market believes that the "stall" of the investment end is a phased weakening driven by "anti - involution" and a policy choice. With the Fed's interest rate cut in September, the potential spill - over effect of overseas monetary policy and the high prosperity of domestic high - tech industries make the "strong expectation" the dominant force in the macro narrative, which is reflected in the bond yield curve [11][18][22]. 3.3 Price Repair is Differentiated, Downward Transmission Needs Observation - In August, the CPI was - 0.4% year - on - year and 0.0% month - on - month, both lower than expected. The decline in the year - on - year CPI was mainly due to weak food prices, while the month - on - month decline was more affected by seasonal factors. The core CPI reached a new high this year, but its repair momentum still needs to be improved. The PPI showed signs of bottom - up repair, but the performance of upstream production materials and downstream living materials was still differentiated. The profit of industrial enterprises increased significantly in August, but it was mainly due to the low base last year, and the improvement in demand was not obvious. In the future, the PPI may continue to rise year - on - year, but the price transmission and the base effect need to be observed [23][24][30]. 3.4 Social Financing Growth Peaked and Declined, M1 Growth Slowed - In August, new RMB loans were lower than expected, and the social financing growth showed signs of peaking. Although the real estate sales data in September showed marginal improvement, considering the high base last year and the front - loaded fiscal efforts this year, it is likely that the social financing growth has peaked this year. The slowdown in social financing affected deposit creation and money supply. The M1 growth continued to rise but is expected to have limited upward space [32][36][43]. 3.5 The Central Bank Cares for Liquidity, but Further Easing is Difficult in the Short Term - In September, the market capital tightened slightly. The central bank took measures to maintain market liquidity, but the current capital price is within the central bank's acceptable range, and further significant decline requires a significant increase in market interest rate cut expectations. The central bank's attitude towards the economic situation is more optimistic, and it emphasizes the implementation of existing policies and the prevention of capital idling [46][47][48]. 3.6 Bond Fund Fees May be Adjusted, Preventive Redemption Increases Market Volatility - In September, the CSRC revised the regulations on public bond fund sales fees, which may affect the stability of bond fund liabilities. As the quarter - end approached, preventive redemptions increased, exacerbating market volatility. If the final regulations are similar to the draft, the bond market may experience a phased over - adjustment; otherwise, the market sentiment may stabilize [55][56]. 3.7 Future Outlook - The "weak reality" of the domestic economy continues, and the bond market is supported by the central bank's liquidity care. However, the "strong expectation" dominates the macro narrative, and the potential adjustment of bond fund fees and tax policies increases market volatility. Treasury bonds can hedge potential expectation differences. In the short term, investors are advised to be cautious about the TL contract and hold a small amount of long positions in bond futures. For arbitrage, the timing needs to be observed [57][59].

Group 1: Report Industry Investment Rating - No industry investment rating information is provided in the report. Group 2: Core Viewpoints of the Report - In October, the coal price is expected to continue its downward trend, and the coal - to - methanol profit will remain high. The domestic methanol operating rate will continue to reach new highs, and the overall domestic supply will be relatively abundant. The import volume is expected to drop to 125 - 130 tons, and the port inventory accumulation will slow down. The overall demand in October has no increment, and it is difficult for traditional demand to show bright spots under the mediocre macro - background [5][91]. - The methanol market is expected to oscillate at the bottom in October. Attention should be paid to the impact of gas restrictions in Iran, with a support level around 2300 yuan/ton [6][91]. Group 3: Summary by Directory 1. Foreword Summary - In October, on the supply side, after the peak summer coal - using season ends, the coal price is expected to decline, and the coal - to - methanol profit will remain high. The domestic methanol operating rate will continue to rise, and the overall supply will be abundant. The import volume will decrease, and the port inventory accumulation will slow down. On the demand side, there is no increment in overall demand, and traditional demand lacks bright spots [5]. - The recommended strategies include unilateral trading (oscillating at the bottom, paying attention to the impact of Iranian gas restrictions with a support level around 2300 yuan/ton), arbitrage (long - term attention to reverse arbitrage opportunities in inter - period arbitrage and repair opportunities in PP - 3MA cross - variety arbitrage), and options trading (selling put options around the lower margin of 2300) [6][7][91]. 2. Fundamental Situation (1) Market Review - In September 2025, the spot price of methanol in mainstream domestic regions showed an overall oscillating and weakening trend. The macro - environment had some support for domestic commodities, but the methanol futures returned to the fundamentals due to factors such as the high port inventory, showing a weak downward trend [11][12]. - On the supply side, the coal - to - methanol profit was high, and the supply in the inland market was loose. In the port area, the MTO device operating rate was stable. The international device operating rate declined from a high level, and the methanol price was weakly operating [17][23][29]. (2) Supply Analysis - From the end of this year to the first half of next year, there will still be some new methanol production capacities put into operation. In 2025, the domestic methanol planned new capacity is 1010 tons, but the actual new capacity for external sales is only 190 tons [31][37]. - In September, the new domestic methanol device production was limited. The coal price first rose and then fell, and the coal - to - methanol profit remained high. The coal - to - methanol operating rate was high, and the domestic supply was loose. In October, the coal price is expected to continue to decline, and the coal - to - methanol profit will still be high. The domestic supply will remain loose, and the enterprise inventory is expected to gradually accumulate [34][41][51]. (3) October Import Forecast - From January to September 2025, the domestic cumulative imported methanol is expected to be about 9.7 million tons. In 2024, the international new methanol capacity was 3.83 million tons, and there will still be a large amount of new international capacity in 2025 [54][62]. - Due to some Iranian devices being shut down, the daily output decreased from 40,000 tons to around 30,000 tons. The October import volume is expected to be maintained at 1.25 million tons. The port inventory accumulation may end [64][67]. (4) October Demand Slightly Increases, but the Macro - level Pressure Remains High - The macro - economic recovery is slow. The manufacturing PMI in August showed some improvement, but trade and geopolitical conflicts still interfere with the domestic macro - situation [73]. - In October, there is no new MTO device put into operation. Some MTO devices are under the pressure of being eliminated. The traditional downstream demand in September is difficult to increase, and the fundamental situation of each sector is differentiated [78][80][88]. 3. Future Outlook and Strategy Recommendation - In October, on the supply side, the coal price will decline, the coal - to - methanol profit will remain high, and the domestic supply will be abundant. The import volume will decrease, and the port inventory accumulation will slow down. On the demand side, there is no increment in overall demand, and traditional demand lacks bright spots [91]. - The recommended strategies include unilateral trading (oscillating at the bottom, paying attention to the impact of Iranian gas restrictions with a support level around 2300 yuan/ton), arbitrage (long - term attention to reverse arbitrage opportunities in inter - period arbitrage and repair opportunities in PP - 3MA cross - variety arbitrage), and options trading (selling put options around the lower margin of 2300) [91].

For trading strategies, it's suggested to hold a wait - and - see attitude for arbitrage and options, and expect a stable - to - strong price trend for the single - side trade [16] - For glass, it's expected to show an oscillating trend before the holiday. The single - side trade may see price oscillations, and it's recommended to hold a wait - and - see attitude for arbitrage and options. There's also a suggestion of a long - glass and short - soda - ash strategy [25] Group 3: Summary According to the Directory 1. Core Logic Analysis 1.1 Soda Ash Supply - This week's soda ash production was 74.6 tons, a week - on - week decrease of 1.5 tons (-2%). Both heavy and light soda decreased. The daily production was 10.6 - 10.8 tons. Supply decreased due to equipment maintenance in some companies and increased with the recovery of others. Boyuan Phase II was ignited on Friday. Juhua has a maintenance plan in October. Seasonal maintenance is rare, and supply is at a high level. Some manufacturers raised prices this week. The cost increased slightly due to rising coal prices. The theoretical profits of both the soda - ammonia method and the combined - alkali method decreased [8] 1.2 Soda Ash Demand - This week's apparent demand for soda ash was 78.8 tons, a 0.2% week - on - week increase. Heavy - soda demand decreased by 2.8%, and light - soda demand increased by 4.6%.

Group 1: Report Industry Investment Rating - Not provided in the content Group 2: Core Viewpoints of the Report - The expectation of the Fed's interest rate cut has increased, and copper prices are consolidating at a high level. Supply - side disturbances have increased, and the center of copper prices has shifted upward. The copper smelting industry's "anti - involution" is expected to unfold, with bullish sentiment fermenting. Although downstream demand for high prices is insufficient and demand is marginally weakening, it will not collapse. The Grasberg accident has strengthened the bullish trend, and prices are expected to continue to be strong [3][4][6] - The global copper market is facing a situation where supply is difficult to ease and demand is showing a differentiated trend. The growth rate of supply and demand has declined compared to last year. It is expected that the global copper market will have a certain amount of surplus in 2025 [123][131] Group 3: Summary According to the Directory 1. Copper Market Overview (1) Market Review - In September, copper prices broke through the pressure level of $10,160/ton. On September 8, the lowest price of Shanghai copper reached 79,400 yuan/ton, or LME copper at $9,860/ton. On September 26, it reached a maximum of 83,090 yuan/ton, or LME copper at $10,485/ton. The Fed cut interest rates by 25 basis points in September, but there were differences among policymakers regarding further rate cuts, and the dovish stance was less than expected. The Grasberg accident led to a 35% decline in the 2026 output forecast, intensifying the tightness of copper mines. The downstream demand for high - priced copper was insufficient, and the destocking speed was slow [11] (2) Market Outlook - In terms of supply, it is expected that the global copper concentrate increment in 2025 will be adjusted down to 200,000 metal tons, with a year - on - year growth of 0.87%. The growth rate of refined copper production is expected to be 3.53%, lower than 4.3% in 2024. In terms of demand, the global consumption growth rate is expected to drop to 3.4%, with China's consumption growth rate falling from 4.5% to 3.8% and overseas demand growth rate rising from 1.8% to 2.7%. In terms of price, the long - term preventive interest rate cuts in the US are expected to drive up inflation, and copper prices are expected to mainly operate in the range of 81,000 - 85,000 yuan/ton [12] (3) Strategy Recommendation - Unilateral: Purchase on dips. Arbitrage: Hold long - short positions across markets. Options: Wait and see [7] 2. Increasing Disturbances in Copper Mines, Difficult to Ease the Tight Supply Situation (1) Sharp Decline in the Increment of Copper Concentrate Supply - It is expected that the global copper concentrate increment in 2025 will be about 200,000 tons, with a year - on - year growth of 0.87%, lower than the increment of 665,500 tons in 2024. Many major mining companies have reduced their production plans, such as Freeport, Ivanhoe, Teck, etc., with a total reduction of 239,000 tons. However, the output of Kazakhmys is expected to increase from 520,000 tons to 600,000 tons [28][29] (2) Mismatch in Global Scrap Copper Supply, Tight Domestic Scrap Copper Supply - In August 2025, China's scrap copper imports reached 179,400 physical tons, with a year - on - year increase of 5.93%. The cumulative import from January to August was 1.5148 million physical tons, with a cumulative year - on - year increase of 0.12%. The import from the US has decreased, but it is imported through countries like Japan and Thailand. The EU is facing a reduction in scrap supply, and it is expected that the import of scrap copper from EU countries will decrease in the future [41] (3) Accelerated Transmission of Insufficient Raw Material Supply to the Smelting End - It is expected that the global refined copper production will increase by 950,000 tons in 2025, with a year - on - year growth of 3.53%. Overseas smelters are facing losses and increasing production cuts, such as Pasar, Altonorte, etc. In China, in August, the electrolytic copper production was 1.1715 million tons, a month - on - month decrease of 0.24%. The domestic raw material supply is supplemented by the inflow of overseas long - term contracts and increased scrap copper procurement [48][50] 3. Consumption Analysis (1) Domestic Demand Differentiation - **Real Estate Market**: From January to August, the national new commercial housing sales area decreased by 4.7% year - on - year. The real estate market is in the off - season, and the decline in construction completion will continue to drag down copper consumption [60] - **Power Grid and Power Supply Projects**: From January to July, the cumulative investment in the power grid was 331.5 billion yuan, a year - on - year increase of 12.5%. The investment in power supply projects increased by 3.4%. In August, the operating rate of wire and cable improved month - on - month but decreased year - on - year. The export of wire and cable maintained growth, but the export to the US decreased due to tariff increases [68][70] - **Household Air - Conditioners**: From January to August, the cumulative sales of household air - conditioners were 152.57 million units, a year - on - year increase of 6.91%. In August, the total sales were 13.023 million units, a slight year - on - year decline. The consumption growth rate of air - conditioners is expected to drop to 5%, and the copper consumption will increase from 1.57 million tons to 1.65 million tons [78][79] - **Automobiles**: In August, automobile production and sales increased month - on - month and year - on - year. However, due to the structural differentiation of the automobile market and the impact of subsidy policies, the growth rate of automobile consumption is expected to gradually slow down [87] (2) The Marginal Weakening of the Driving Force of New Energy on Global Consumption - **New Energy Vehicles**: From January to July 2025, the global new energy vehicle sales increased by 24.57% year - on - year. China led the market, with production and sales from January to August increasing by 37.3% and 36.7% respectively. The global new energy vehicle copper consumption is expected to increase from 1.2208 million tons in 2024 to 1.3524 million tons in 2025 [93][94] - **Wind and Solar Power Generation**: From January to July 2025, China's new photovoltaic installed capacity increased by 80.73% year - on - year, and the new wind power installed capacity increased by 79.44% year - on - year. The global new wind power installed capacity is expected to increase to 138GW in 2025. The contribution of wind and solar power to global consumption growth is declining [105][117] (3) Consumption Summary - It is expected that the global consumption growth rate will drop to 3.4%, lower than 3.76% last year. China's consumption growth rate will drop from 4.5% to 3.8%. Overseas demand remains stable, while domestic demand is marginally weakening in the second half of the year [123] 4. Supply - Demand Balance Sheet - In 2025, the supply gap of copper concentrate is expected to widen to 943,000 tons, and the refined copper surplus is expected to be 377,000 tons, concentrated in the US. In China, the consumption growth rate is expected to decline significantly from October to December [131]
