南华期货玉米、淀粉产业周报：主动卖压减小引发玉米价格上行-20251117

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - This year, China's corn production is expected to reach 300 million tons for the first time in history. With the harvest almost complete, the supply - demand structure is gradually moving towards balance. In the long - term, there is a tight supply expectation under mild production increase pressure, weakening import pressure, and stable demand [1]. - In the short - term, the corn market has shown a strong performance due to reduced supply and downstream price - raising purchases. However, the price may face intermittent pressure as the selling peak at the end of the year tests its resilience [1]. - The corn starch market has also run strongly this week, supported by rising raw material prices, good order shipments, and tight local supply [1]. - The CBOT corn futures rose more than 1% this week, but the bearish November supply - demand data led to a sharp decline on Friday, erasing most of the gains from Monday to Thursday [1]. 3. Summary by Relevant Catalogs 3.1 Core Contradictions and Strategy Recommendations 3.1.1 Core Contradictions - Near - term trading logic: In the Northeast, state reserve purchases support the market, and in North China, the reluctance to sell has reduced short - term supply. The downstream's price - raising purchases have supported the weekly strength of the corn market. China's corn production increase is certain, and the market is still digesting the price pressure from the production increase. The corn price is mainly oscillating at the bottom [7]. - Long - term trading expectations: China's corn supply - demand contradiction is not prominent. With a sharp reduction in corn and substitute grain imports and a possible decrease in high - quality corn production in North China, the medium - term supply - demand structure may tighten. The price is likely to form an important bottom in the fourth - quarter supply peak, and buyers should pay attention to the participation opportunities at the price bottom [7]. 3.1.2 Trading Strategy Recommendations - Trend judgment: The sign of the end of the pull - back is more obvious, and the probability of finding the bottom continues to increase. Technically, the 01 contract is supported at the 2100 - yuan mark and rebounds along the 5 - day moving average [8]. - Strategy suggestions: Mid - and downstream enterprises should be aware of the risk of rising long - term procurement costs. Grain - holding entities with low - cost inventory can consider partial inventory hedging at high prices to avoid pull - back risks [8]. - Basis, monthly spread, and hedging arbitrage strategies: - Basis strategy: The spot and futures prices are moving in sync, with a weaker increase in the production area. The port basis fluctuates narrowly, and no strategy is recommended [8]. - Monthly spread strategy: The decrease in spot supply has led the near - month 01 contract to perform strongly, narrowing the spread between near - and far - month contracts. The "sell near, buy far" strategy is temporarily withdrawn for observation [8]. - Hedging arbitrage strategy: Due to the fundamentals of soybeans and corn, it is not suitable for inter - variety arbitrage. The wheat - corn spread has narrowed but is still outside the substitution range. The starch - corn spread has little change, and the "buy starch, sell corn" arbitrage is not recommended for now. The pig - grain ratio's rebound space is uncertain, and arbitrage is on hold [11][12]. 3.1.3 Industrial Customer Operation Suggestions - Price range forecast: The predicted monthly price range for corn is 2050 - 2200 yuan, with a current volatility of 8.25% and a volatility percentile of 38.4%. For starch, it is 2350 - 2550 yuan, with a volatility of 7.81% and a volatility percentile of 15.39% [18]. - Risk strategies for the fourth quarter: Different strategies are recommended for inventory management and procurement management, including shorting corn futures, selling call options, selling put options, and buying far - month contracts, with corresponding scenarios, hedging tools, trading directions, and suggested entry intervals [18]. 3.2 This Week's Important Information and Next Week's Key Events 3.2.1 This Week's Important Information - Positive information: State reserve purchases continue to support the market, the early sales progress is fast, and farmers' reluctance to sell has reduced the effective circulating grain sources. Terminal enterprises have to raise prices to increase arrivals [19]. - Negative information: The increase in U.S. corn supply pressure due to the bearish USDA supply - demand report, and the possible increase in selling pressure after the price rises [20]. 3.2.2 Next Week's Key Events - Monitor whether the price increase stimulates an increase in selling pressure [20]. 3.3 Disk Interpretation 3.3.1 Price - Volume and Capital Interpretation - Domestic market: The corn futures market has continued to strengthen this week. The main 01 contract rose 1.68% to 2185 yuan/ton, with a decrease in open interest, a slight increase in trading volume, and an increase in registered positions. The starch market has also strengthened in sync with corn, with a similar increase rate [20][21]. - International market: The CBOT corn futures rose more than 1% this week but fell sharply on Friday due to bearish supply - demand data, and the rebound trend has weakened [53]. 3.3.2 Basis, Monthly Spread, and Starch - Corn Spread - Basis structure: After the new season started, the basis between the mainstream price at Jinzhou Port and the main contract is in a reasonable range, with little change. However, the basis in the production areas has weakened [25]. - Monthly spread structure: The spread between near - and far - month corn contracts has weakened this week, and the term structure has flattened. The starch basis in the main production areas has also weakened [35]. - Starch - corn spread: The spread has fluctuated slightly this week, and the "buy starch, sell corn" arbitrage is not recommended for now [49]. 3.4 Valuation and Profit Analysis 3.4.1 Upstream and Downstream Industry Chain Profit Tracking - Planting profit: It is better than last year, especially in the Northeast production area [57]. - Trading profit: The stable and strengthening corn price is conducive to trading enterprises' purchasing and sales activities, and the inventory profit is improving [57]. - Deep - processing profit: The profit from corn - to - starch has slightly declined due to the rebound in corn prices and limited follow - up of starch spot prices. The profit from the corn - to - ethanol industry has continued to decline [57]. - Disk profit: The basis at Jinzhou Port is neutral, and the disk profit is not obvious. There is hedging profit for far - month contracts, but considering the bottom of the spot price, it is not advisable to enter the market for hedging [57]. 3.4.2 Import - Export Profit Tracking The import profit of corn has increased as the domestic price has risen more strongly than the international price [59]. 3.5 Supply - Demand and Inventory Projection 3.5.1 Supply - Demand Balance Sheet Projection - China's corn: The supply - demand balance sheet shows changes in planting area, production, import, consumption, and inventory in different years. The annual surplus is expected to be 3.55 million tons in 2025/26 [63]. - Global corn: The world's corn supply - demand balance sheet shows changes in beginning inventory, production, import, consumption, export, and ending inventory in different years. The stock - to - use ratio is expected to be 21.97% in 2025/26 [64]. 3.5.2 Supply - Side and Projection - Domestic supply: In November, the corn supply is gradually decreasing from the peak. The selling pressure will be reduced as the temperature drops in the Northeast. The proportion of high - quality corn in North China has decreased due to rainfall. Although the overall supply is still high, there may be a shortage of high - quality corn [65]. - Import: From January to September 2025, China's cumulative import of corn and corn flour was 930,000 tons, a year - on - year decrease of 92.7%. In September, the import was 60,000 tons, a year - on - year decrease of 81.9%. It is expected that the import volume will remain low in the fourth quarter [65]. - Inventory: The port corn inventory has not increased significantly, and the overall inventory is still at a low level, providing space for future corn purchasing and sales [67]. - Foreign corn: The U.S. corn harvest is nearing completion, and the supply pressure is high. The bearish USDA supply - demand report on the 14th has increased the supply pressure [69]. 3.5.3 Demand - Side and Projection - Consumption: The operating rates of major products have continued to rise. The feed demand is supported by the peak slaughter season and secondary fattening, and the overall demand in the fourth quarter remains good [71]. - Feed demand: It is expected to remain at a high level in the fourth quarter. The feed production is high, and the feed enterprise inventory has rebounded but is still at a low level. The pig - raising profit has changed little this week, and the reduction of pig production capacity may affect the corn feed demand in 2026 [71]. - Deep - processing demand: The fourth quarter is the traditional peak season for corn deep - processing products. The low - price corn has attracted downstream enterprises to increase their operating rates, driving up corn consumption. However, the growth trend has slowed down due to rising raw material prices and insufficient price increases for terminal products [74].
